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 = RHEL 9.x x86_64
IP Address= any
Host Name = any.cmdschool.org
2.1.2 安装常用工具
yum install -y vim bzip2 wget net-tools
2.1.3 配置编译环境
yum install -y gcc gcc-c++ make expat-devel autoconf
2.1.4 下载php二进制安装包
cd ~ wget --no-check-certificate https://www.php.net/distributions/php-8.2.11.tar.bz2
如果需要其他版本或者下载异常，请从以下连接下载，
https://www.php.net/releases/
2.1.5 创建运行用户
groupadd -g 48 apache useradd -u 48 -g 48 -d /usr/share/httpd -s /sbin/nologin apache

注：可防任意脚本注入
2.3.3 修改时区
sed -i 's/;date.timezone =/date.timezone = Asia\/Shanghai/g' /etc/php.ini
2.3.4 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 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.

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'

; - '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 the child processes. This can be used only if the master
; process running user is root. It is set after the child process is created.
; The user and group can be specified either by their name or by their numeric
; IDs.
; Note: If the user is root, the executable needs to be started with
; --allow-to-run-as-root option to work.
; Default Values: The user is set to master process running user by default.
; If the group is not set, the user's group is used.
user = apache
group = apache
; The address on which to accept FastCGI requests.
; Valid syntaxes are:

; '/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 Linux, 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: Owner is set to the master process running user. If the group
; is not set, the owner's group is used. Mode is set to 0660.
;listen.owner = apache
;listen.group = apache

; 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

; Set the associated the route table (FIB). FreeBSD only
; Default Value: -1
;listen.setfib = 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

; unless it specified otherwise
; Default Value: no set
; process.priority = -19
; Set the process dumpable flag (PR_SET_DUMPABLE prctl for Linux or

; 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;

; 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 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;
; start since - number of seconds since FPM has started;
; accepted conn - the number of request accepted by the pool;
; listen queue - the number of request in the queue of pending
; connections (see backlog in listen(2));
; max listen queue - the maximum number of requests in the queue
; of pending connections since FPM has started;
; listen queue len - the size of the socket queue of pending connections;
; idle processes - the number of idle processes;
; active processes - the number of active processes;
; total processes - the number of idle + active processes;
; max active processes - the maximum number of active processes since FPM
; has started;
; max children reached - number of times, the process limit has been reached,
; when pm tries to start more children (works only for
; pm 'dynamic' and 'ondemand');
; Value are updated in real time.
; Example output:
; pool: www
; process manager: static
; start time: 01/Jul/2011:17:53:49 +0200
; start since: 62636
; accepted conn: 190460

; max listen queue: 1
; listen queue len: 42
; idle processes: 4
; active processes: 11
; total processes: 15
; max active processes: 12
; max children reached: 0
;
; By default the status page output is formatted as text/plain. Passing either
; 'html', 'xml' or 'json' in the query string will return the corresponding
; output syntax. Example:
; http://www.foo.bar/status
; http://www.foo.bar/status?json
; http://www.foo.bar/status?html
; http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the
; query string will also return status for each pool process.
; Example:
; 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
; The Full status returns for each process:
; pid - the PID of the process;
; state - the state of the process (Idle, Running, ...);
; start time - the date and time the process has started;
; start since - the number of seconds since the process has started;
; requests - the number of requests the process has served;
; request duration - the duration in µs of the requests;
; request method - the request method (GET, POST, ...);
; request URI - the request URI with the query string;
; content length - the content length of the request (only with POST);
; 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
; processing has terminated;
; last request memory - the max amount of memory the last request consumed
; it's always 0 if the process is not in Idle state
; because memory calculation is done when the request
; processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related to
; the current request being served.
; Example output:

; 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
pgrep -u apache php-fpm -a netstat -antp | grep php-fpm
2.3.7 手动关闭服务
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 ExecStartPre=/bin/bash -c "mkdir -p /run/php-fpm" 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.

配置环境文件，
echo '# Additional environment file for php-fpm' > /etc/sysconfig/php-fpm
重载控制脚本
systemctl daemon-reload
2.4.2 启动服务并配置默认启动
systemctl start php-fpm systemctl enable php-fpm
2.4.3 服务其他控制命令
systemctl start php-fpm systemctl restart php-fpm systemctl stop php-fpm systemctl status php-fpm
3 加载PHP-FPM模块
