如何部署laravel框架的运行环境?

Laravel

1 理论部分

Laravel是一套简洁、优雅的PHP Web开发框架(PHP Web Framework)。它可以让你从面条一样杂乱的代码中解脱出来;它可以帮你构建一个完美的网络APP,而且每行代码都可以简洁、富于表达力。

2 实验部分

2.1 实验环境

lfSer:
hostname=laravel-fastCGI
ipaddress=10.168.0.177

client:
hostnmae=client
ipaddress=10.168.0.8

2.2 yum源的安装

In lfSer

yum install -y https://mirror.webtatic.com/yum/el6/latest.rpm 
yum install -y httpd php56w php56w-fpm php56w-mysql php56w-pdo php56w-mbstring php56w-mcrypt php56w-pear
yum install -y mysql mysql-server
yum -y install wget unzip

2.3 配置部分

In lfSer

2.3.1 step1

1)检查是否引入php模块(默认开启),主配置文件:

grep ^Include /etc/httpd/conf/httpd.conf

包含如下内容:

Include conf.d/*.conf

查看PHP支持模块配置文件:

less /etc/httpd/conf.d/php.conf

包含如下内容:

<IfModule prefork.c>
 LoadModule php5_module modules/libphp5.so
</IfModule>
<IfModule worker.c>
 LoadModule php5_module modules/libphp5-zts.so
</IfModule>
 
AddHandler php5-script .php
AddType text/html .php
 
DirectoryIndex index.php

2)关闭apache的php模块

mv /etc/httpd/conf.d/php.conf /etc/httpd/conf.d/php.conf.default

2.3.2 step2

启动httpd&mysqld服务:

/etc/init.d/php-fpm start
chkconfig php-fpm on
/etc/init.d/httpd start
chkconfig httpd on
/etc/init.d/mysqld start
chkconfig mysqld on

注:关于MySQL的安全配置请运行,这里不再详述!

mysql_secure_installation

2.3.3 step3

配置httpd服务:

vim /etc/httpd/conf/httpd.conf

修改如下配置:

ServerName www.cmdschool.org:80
NameVirtualHost *:80

2.3.4 step4(可选)

1)下载composer并全局安装

curl -sS https://getcomposer.org/installer | php

2)查看全局命令目录

echo $PATH

显示如下:

/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

3)移动composer执行文件到全局命令目录(选择分隔符”:”的一段路径)

mv composer.phar /usr/local/bin/composer

2.3.5 step5

安装框架
1)下载框架

wget http://down.golaravel.com/laravel/laravel-master.zip

2)解压框架

unzip laravel-master.zip

3)拷贝框架到指定目录

mkdir /var/www/www.cmdschool.org
cp -rf laravel-master/* www.cmdschool.org/

2.3.6 step6

权限设置
1)目录权限设置

chown :apache -R www.cmdschool.org
chmod 770 -R www.cmdschool.org

2)确保selinux是Enforcing状态:

getenforce

3)恢复预设的selinux type:

restorecon -RFvv /var/www/www.cmdschool.org/

4)检查当前的selinux type:

ll -dZ /var/www/www.cmdschool.org/

2.3.7 step7

设置虚拟目录:

vim /etc/httpd/conf.d/www.cmdschool.org.conf

加入如下配置:

<VirtualHost *:80>
 ServerName www.cmdschool.org
 
 DocumentRoot /var/www/www.cmdschool.org/public/
 <Directory /var/www/www.cmdschool.org/public/>
 Options FollowSymlinks
 DirectoryIndex index.php
 AllowOverride All
 Order allow,deny
 Allow from all
 </Directory>
 
 <LocationMatch "^(.*\.php)$">
 ProxyPassMatch fcgi://127.0.0.1:9000/var/www/www.cmdschool.org/public/
 </LocationMatch>
 
 LogLevel debug
 ErrorLog /var/log/apache2/www.cmdschool.org.error.log
 CustomLog /var/log/apache2/www.cmdschool.org.access.log combined
</VirtualHost>

8)重启httpd服务:

/etc/init.d/php-fpm restart
/etc/init.d/httpd restart

2.3.8 step8

设置防火墙:

vim /etc/sysconfig/iptables

加入如下行:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

重启防火墙:

/etc/init.d/iptables restart

2.3.9 step9

In Client:
以下在windows客户端下测试:
1)修改本机的hosts(相当于dns解析)

notepad %SystemRoot%\System32\drivers\etc\hosts

增加如下内容:

10.168.0.177 www.cmdschool.org

2)浏览器测试
浏览器测试你可以看到如下提示:

3)日志的排查方法
In lfSer:
参阅如下日志可知属于代码级别的错误,排查方法如下:
配置文件日志:

tail -f /var/log/apache2/www.cmdschool.org.error.log


监看以上信息表明PHP代码已经完成送到fastCGI网关

tail -f /var/log/php-fpm/error.log


监看以上日志无任何反应,证明php-fpm解析php代码无任何异常。

tail -f /var/www/www.cmdschool.org/storage/logs/laravel.log


监看以上信息发现错误,可见这种错误是框架已经预见的,应该由php程序员处理,与运维无关。
