如何编译安装PHP-FPM?

PHP

1 前言

一个问题,一篇文章,一出故事。
PHP-FPM可以跟Nginx配合使Nginx环境具备运行解析PHP脚本的能力。
PHP-FPM常见环境有LNMP即Linux+Ngingx+MySQL+PHP。

2 安装PHP-FPM

2.1 环境配置

2.1.1 准备操作系统

OS = Oracle Linux Server release 9.0
IP Address= any
Host Name = any.cmdschool.org

2.1.2 配置编译环境

yum -y install gcc gcc-c++ make expat-devel yum autoconf

2.1.3 下载php二进制安装包

cd ~
wget https://www.php.net/distributions/php-8.1.12.tar.bz2

2.1.4 创建运行用户

groupadd  -g 48 apache
useradd -u 48 -g 48 -d /usr/share/httpd -s /sbin/nologin apache

2.1.5 预建目录

mkdir /var/log/php-fpm/
mkdir /run/php-fpm/

2.1.6 配置防火墙(可选)

firewall-cmd --permanent --add-port 9000/tcp
firewall-cmd --reload
firewall-cmd --list-all

2.2 编译安装

2.2.1 解压安装包

cd ~/
tar -xf php-8.1.12.tar.bz2

2.2.2 安装前构建

cd ~/php-8.1.12
./configure --bindir=/usr/sbin/ \
            --sbindir=/usr/sbin/ \
            --sysconfdir=/etc/ \
            --libdir=/usr/lib64/  \
            --mandir=/usr/share/man/ \
            --includedir=/usr/include/ \
            --with-fpm-user=apache \
            --with-fpm-group=apache \
            --enable-fpm \
            --with-fpm-systemd \
            --with-mysqli \
            --enable-mbstring

如果遇到如下错误,

configure: error: Package requirements (libxml-2.0 >= 2.9.0) were not met:

可通过如下命令解决依赖关系,

dnf install -y libxml2-devel

如果遇到如下错误,

configure: error: Package requirements (sqlite3 >= 3.7.7) were not met:

可通过如下命令解决依赖关系,

dnf install -y sqlite-devel

如果遇到如下错误,

configure: error: Package requirements (oniguruma) were not met:

install -y oniguruma-devel

如果遇到如下错误,

configure: error: Package requirements (libsystemd >= 209) were not met:

可通过如下命令解决依赖关系,

dnf install -y systemd-devel

2.2.3 编译并安装

make
make install | tee install.log

2.3 配置PHP-FPM

2.3.1 配置php.ini

cp php.ini-development /etc/php.ini
ln -s /etc/php.ini /usr/lib64/php.ini

2.3.2 防止空文件递给PHP-FPM后端

vim /etc/php.ini

修改以下参数,

cgi.fix_pathinfo = 0

注:可防任意脚本注入

2.3.3 创建配置

cp ./sapi/fpm/php-fpm.conf /etc/php-fpm.conf
vim /etc/php-fpm.conf

配置修改如下,

;;;;;;;;;;;;;;;;;;;;;
; FPM Configuration ;
;;;;;;;;;;;;;;;;;;;;;

; All relative paths in this configuration file are relative to PHP's install
; prefix (/usr/local). This prefix can be dynamically changed by using the
; '-p' argument from the command line.

;;;;;;;;;;;;;;;;;;
; Global Options ;
;;;;;;;;;;;;;;;;;;

[global]
; Pid file
; Note: the default prefix is /usr/local/var
; Default Value: none
pid = /run/php-fpm/php-fpm.pid

; Error log file
; If it's set to "syslog", log is sent to syslogd instead of being written
; into a local file.
; Note: the default prefix is /usr/local/var
; Default Value: log/php-fpm.log
error_log = /var/log/php-fpm/error.log

; syslog_facility is used to specify what type of program is logging the
; message. This lets syslogd specify that messages from different facilities
; will be handled differently.
; See syslog(3) for possible values (ex daemon equiv LOG_DAEMON)
; Default Value: daemon
;syslog.facility = daemon

; syslog_ident is prepended to every message. If you have multiple FPM
; instances running on the same server, you can change the default value
; which must suit common needs.
; Default Value: php-fpm
;syslog.ident = php-fpm

; Log level
; Possible Values: alert, error, warning, notice, debug
; Default Value: notice
;log_level = notice

; Log limit on number of characters in the single line (log entry). If the
; line is over the limit, it is wrapped on multiple lines. The limit is for
; all logged characters including message prefix and suffix if present. However
; the new line character does not count into it as it is present only when
; logging to a file descriptor. It means the new line character is not present
; when logging to syslog.
; Default Value: 1024
;log_limit = 4096

; Log buffering specifies if the log line is buffered which means that the
; line is written in a single write operation. If the value is false, then the
; data is written directly into the file descriptor. It is an experimental
; option that can potentially improve logging performance and memory usage
; for some heavy logging scenarios. This option is ignored if logging to syslog
; as it has to be always buffered.
; Default value: yes
;log_buffering = no

; If this number of child processes exit with SIGSEGV or SIGBUS within the time
; interval set by emergency_restart_interval then FPM will restart. A value
; of '0' means 'Off'.
; Default Value: 0
;emergency_restart_threshold = 0

; Interval of time used by emergency_restart_interval to determine when
; a graceful restart will be initiated.  This can be useful to work around
; accidental corruptions in an accelerator's shared memory.
; Available Units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value: 0
;emergency_restart_interval = 0

; Time limit for child processes to wait for a reaction on signals from master.
; Available units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value: 0
;process_control_timeout = 0

; The maximum number of processes FPM will fork. This has been designed to control
; the global number of processes when using dynamic PM within a lot of pools.
; Use it with caution.
; Note: A value of 0 indicates no limit
; Default Value: 0
; process.max = 128

; Specify the nice(2) priority to apply to the master process (only if set)
; The value can vary from -19 (highest priority) to 20 (lowest priority)
; Note: - It will only work if the FPM master process is launched as root
;       - The pool process will inherit the master process priority
;         unless specified otherwise
; Default Value: no set
; process.priority = -19

; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging.
; Default Value: yes
;daemonize = yes

; Set open file descriptor rlimit for the master process.
; Default Value: system defined value
;rlimit_files = 1024

; Set max core size rlimit for the master process.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; Specify the event mechanism FPM will use. The following is available:
; - select     (any POSIX os)
; - poll       (any POSIX os)
; - epoll      (linux >= 2.5.44)
; - kqueue     (FreeBSD >= 4.1, OpenBSD >= 2.9, NetBSD >= 2.0)
; - /dev/poll  (Solaris >= 7)
; - port       (Solaris >= 10)
; Default Value: not set (auto detection)
;events.mechanism = epoll

; When FPM is built with systemd integration, specify the interval,
; in seconds, between health report notification to systemd.
; Set to 0 to disable.
; Available Units: s(econds), m(inutes), h(ours)
; Default Unit: seconds
; Default value: 10
;systemd_interval = 10

;;;;;;;;;;;;;;;;;;;;
; Pool Definitions ;
;;;;;;;;;;;;;;;;;;;;

; Multiple pools of child processes may be started with different listening
; ports and different management options.  The name of the pool will be
; used in logs and stats. There is no limitation on the number of pools which
; FPM can handle. Your system will tell you anyway :)

; Include one or more files. If glob(3) exists, it is used to include a bunch of
; files from a glob(3) pattern. This directive can be used everywhere in the
; file.
; Relative path can also be used. They will be prefixed by:
;  - the global prefix if it's been set (-p argument)
;  - /usr/local otherwise
include=/etc/php-fpm.d/*.conf

根据配置的需求,你需要创建如下夹,

mkdir -p /etc/php-fpm.d/

且创建以下配置文件,

cp ./sapi/fpm/www.conf /etc/php-fpm.d/www.conf
vim /etc/php-fpm.d/www.conf

配置修改如下,

; Start a new pool named 'www'.
; the variable $pool can be used in any directive and will be replaced by the
; pool name ('www' here)
[www]

; Per pool prefix
; It only applies on the following directives:
; - 'access.log'
; - 'slowlog'
; - 'listen' (unixsocket)
; - 'chroot'
; - 'chdir'
; - 'php_values'
; - 'php_admin_values'
; When not set, the global prefix (or NONE) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
user = apache
group = apache

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
;                            a specific port;
;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all addresses
;                            (IPv6 and IPv4-mapped) on a specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = 127.0.0.1:9000

; Set listen(2) backlog.
; Default Value: 511 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 511

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions. The owner
; and group can be specified either by name or by their numeric IDs.
; Default Values: user and group are set as the running user
;                 mode is set to 0660
;listen.owner = apache
;listen.group = apache
;listen.mode = 0660
; When POSIX Access Control Lists are supported you can set them using
; these options, value is a comma separated list of user/group names.
; When set, listen.owner and listen.group are ignored
;listen.acl_users =
;listen.acl_groups =

; List of addresses (IPv4/IPv6) of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.
; Default Value: any
;listen.allowed_clients = 127.0.0.1

; Specify the nice(2) priority to apply to the pool processes (only if set)
; The value can vary from -19 (highest priority) to 20 (lower priority)
; Note: - It will only work if the FPM master process is launched as root
;       - The pool processes will inherit the master process priority
;         unless it specified otherwise
; Default Value: no set
; process.priority = -19

; Set the process dumpable flag (PR_SET_DUMPABLE prctl) even if the process user
; or group is different than the master process user. It allows to create process
; core dump and ptrace the process for the pool user.
; Default Value: no
; process.dumpable = yes

; Choose how the process manager will control the number of child processes.
; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;
;   dynamic - the number of child processes are set dynamically based on the
;             following directives. With this process management, there will be
;             always at least 1 children.
;             pm.max_children      - the maximum number of children that can
;                                    be alive at the same time.
;             pm.start_servers     - the number of children created on startup.
;             pm.min_spare_servers - the minimum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is less than this
;                                    number then some children will be created.
;             pm.max_spare_servers - the maximum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is greater than this
;                                    number then some children will be killed.
;             pm.max_spawn_rate    - the maximum number of rate to spawn child
;                                    processes at once.
;  ondemand - no children are created at startup. Children will be forked when
;             new requests will connect. The following parameter are used:
;             pm.max_children           - the maximum number of children that
;                                         can be alive at the same time.
;             pm.process_idle_timeout   - The number of seconds after which
;                                         an idle process will be killed.
; Note: This value is mandatory.
pm = dynamic

; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI. The below defaults are based on a server without much resources. Don't
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
; Note: This value is mandatory.
pm.max_children = 50

; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'

; The number of seconds after which an idle process will be killed.
; Note: Used only when pm is set to 'ondemand'
; Default Value: 10s
;pm.process_idle_timeout = 10s;

; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
;pm.max_requests = 500

; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. It shows the following information:
;   pool                 - the name of the pool;
;   process manager      - static, dynamic or ondemand;
;   start time           - the date and time FPM has started;

;   http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the

;   http://www.foo.bar/status?full
;   http://www.foo.bar/status?json&full
;   http://www.foo.bar/status?html&full
;   http://www.foo.bar/status?xml&full

;   user                 - the user (PHP_AUTH_USER) (or '-' if not set);
;   script               - the main script called (or '-' if not set);
;   last request cpu     - the %cpu the last request consumed
;                          it's always 0 if the process is not in Idle state
;                          because CPU calculation is done when the request

; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
slowlog = /var/log/php-fpm/www-slow.log

; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_slowlog_timeout = 0

; Depth of slow log stack trace.
; Default Value: 20
;request_slowlog_trace_depth = 20

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the 'max_execution_time' ini option
; does not stop script execution for some reason. A value of '0' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_terminate_timeout = 0

; The timeout set by 'request_terminate_timeout' ini option is not engaged after
; application calls 'fastcgi_finish_request' or when application has finished and
; shutdown functions are being called (registered via register_shutdown_function).
; This option will enable timeout limit to be applied unconditionally
; even in such cases.
; Default Value: no
;request_terminate_timeout_track_finished = no

; Set open file descriptor rlimit.
; Default Value: system defined value
;rlimit_files = 1024

; Set max core size rlimit.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: you can prefix with '$prefix' to chroot to the pool prefix or one
; of its subdirectories. If the pool prefix is not set, the global prefix
; will be used instead.
; Note: chrooting is a great security feature and should be used whenever
;       possible. However, all PHP paths will be relative to the chroot
;       (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =

; Chdir to this directory at the start.
; Note: relative path can be used.
; Default Value: current directory or / when chroot
;chdir = /var/www

; Redirect worker stdout and stderr into main error log. If not set, stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Note: on highloaded environment, this can cause some delay in the page
; process time (several ms).
; Default Value: no
;catch_workers_output = yes

; Decorate worker output with prefix and suffix containing information about
; the child that writes to the log and if stdout or stderr is used as well as
; log level and time. This options is used only if catch_workers_output is yes.
; Settings to "no" will output data as written to the stdout or stderr.
; Default value: yes
;decorate_workers_output = no

; Clear environment in FPM workers
; Prevents arbitrary environment variables from reaching FPM worker processes
; by clearing the environment in workers before env vars specified in this
; pool configuration are added.
; Setting to "no" will make all environment variables available to PHP code
; via getenv(), $_ENV and $_SERVER.
; Default Value: yes
;clear_env = no

; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; execute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
;security.limit_extensions = .php .php3 .php4 .php5 .php7

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp

; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
;   php_value/php_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call 'ini_set'.
;   php_admin_value/php_admin_flag - these directives won't be overwritten by
;                                     PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite previously defined php.ini values, but will append the new value
; instead.

; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr/local)

; Default Value: nothing is defined by default except the values in php.ini and
;                specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
;php_flag[display_errors] = off
php_admin_value[error_log] = /var/log/php-fpm/www-error.log
php_admin_flag[log_errors] = on
;php_admin_value[memory_limit] = 32M

; Set session path to a directory owned by process user
php_value[session.save_handler] = files
php_value[session.save_path] = /var/lib/php/session

根据以上配置的需求,你需要手动建立如下目录,

mkdir -p /var/lib/php/session/
chown -R apache: /var/lib/php/session/

2.3.5 测试fpm启动

/usr/sbin/php-fpm &

2.3.6 查询服务状态

kill 2 `pgrep -u root php-fpm`

2.4 配置服务启动

2.4.1 配置启动脚本

cp ./sapi/fpm/php-fpm.service /usr/lib/systemd/system/php-fpm.service
vim /usr/lib/systemd/system/php-fpm.service

加入如下配置,

# It's not recommended to modify this file in-place, because it
# will be overwritten during upgrades.  If you want to customize,
# the best way is to use the "systemctl edit" command.

[Unit]
Description=The PHP FastCGI Process Manager
After=network.target

[Service]
Type=notify
PIDFile=/run/php-fpm/php-fpm.pid
ExecStart=/usr/sbin/php-fpm --nodaemonize --fpm-config /etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID

# Set up a new file system namespace and mounts private /tmp and /var/tmp directories
# so this service cannot access the global directories and other processes cannot
# access this service's directories.
PrivateTmp=true

# Mounts the /usr, /boot, and /etc directories read-only for processes invoked by this unit.
ProtectSystem=full

# Sets up a new /dev namespace for the executed processes and only adds API pseudo devices
# such as /dev/null, /dev/zero or /dev/random (as well as the pseudo TTY subsystem) to it,
# but no physical devices such as /dev/sda.
PrivateDevices=true

# Explicit module loading will be denied. This allows to turn off module load and unload
# operations on modular kernels. It is recommended to turn this on for most services that
# do not need special file systems or extra kernel modules to work.
ProtectKernelModules=true

# Kernel variables accessible through /proc/sys, /sys, /proc/sysrq-trigger, /proc/latency_stats,
# /proc/acpi, /proc/timer_stats, /proc/fs and /proc/irq will be made read-only to all processes
# of the unit. Usually, tunable kernel variables should only be written at boot-time, with the
# sysctl.d(5) mechanism. Almost no services need to write to these at runtime; it is hence
# recommended to turn this on for most services.
ProtectKernelTunables=true

# The Linux Control Groups (cgroups(7)) hierarchies accessible through /sys/fs/cgroup will be
# made read-only to all processes of the unit. Except for container managers no services should
# require write access to the control groups hierarchies; it is hence recommended to turn this on
# for most services
ProtectControlGroups=true

# Any attempts to enable realtime scheduling in a process of the unit are refused.
RestrictRealtime=true

# Restricts the set of socket address families accessible to the processes of this unit.
# Protects against vulnerabilities such as CVE-2016-8655
RestrictAddressFamilies=AF_INET AF_INET6 AF_NETLINK AF_UNIX

# Takes away the ability to create or manage any kind of namespace
RestrictNamespaces=true

[Install]
WantedBy=multi-user.target
