如何在CentOS 6上通过YUM安装Nginx和PHP-FPM

开始安装Nginx和PHP-FPM之前,你必须卸载系统中以前安装的Apache和PHP。用root登录输入下面的命令：

# yum remove httpd* php*

增加额外资源库

    默认情况下，CentOS的官方资源是没有php-fpm的, 但我们可以从Remi的RPM资源中获得，它依赖于EPEL资源。我们可以这样增加两个资源库：

# yum install yum-priorities -y
# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-7.noarch.rpm
# rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

如果你想在系统启动时自动运行php-fpm，输入下列命令：

# chkconfig --level 345 php-fpm on

PHP仅安装了核心模块，你很可能需要安装其他的模块，比如MySQL、 XML、 GD等等，你可以输入下列命令：

# yum --enablerepo=remi install php-gd php-mysql php-mbstring php-xml php-mcrypt

第一次启动php-fpm，输入下列命令：

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

输出样例

Starting php-fpm:                                          [ OK ]

配置PHP-FPM和Nginx，让他们一起工作

nginx的配置文件在/etc/nginx/nginx.conf，输入下列命令编辑这个文件：

# vi /etc/nginx/nginx.conf

像下面这样编辑取消注释：

       ...
location / {
           root   /usr/share/nginx/html;
           index  index.html index.htm index.php;
       }
       ...
location ~ \.php$ {
           root           html;
           fastcgi_pass   127.0.0.1:9000;
           fastcgi_index  index.php;
           fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
           include        fastcgi_params;
       }
       ...

重启Nginx会重新读取配置文件，输入

# /etc/init.d/nginx reload

现在在 document root目录下建立下列PHP文件

# vi /usr/share/nginx/html/info.php

文件内容如下：

phpinfo();
?>

访问 http://YOUR-SERVER-IP

Nginx虚拟主机设置

设置例子

IP: 192.168.1.113
Domain: domain.local
Hosted at: /home/www/domain.local

输入下列命令新建名叫“www”的用户

# useradd www

创建必要的目录

# mkdir -p /home/www/domain.local/public_html
# mkdir -p /home/www/domain.local/log
# chown -R www.www /home/www/
# chmod 755 /home/www/

创建虚拟主机配置文件

# cd /etc/nginx/conf.d/
# cp virtual.conf www.conf

输入下面命令打开www.conf文件

# vi /etc/nginx/conf.d/www.conf

增加以下配置

server {
        server_name  domain.local;
        root /home/www/domain.local/public_html;
        access_log /home/www/domain.local/log/domain.local-access.log;
        error_log /home/www/domain.local/log/domain.local-error.log;

        location / {
                index  index.html index.htm index.php;
        }
        location ~ \.php$ {
                include /etc/nginx/fastcgi_params;
                fastcgi_pass  127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }
}

你可以用下列方法检查配置文件是否有语法错误

# /etc/init.d/nginx configtest

输出样例

the configuration file /etc/nginx/nginx.conf syntax is ok
configuration file /etc/nginx/nginx.conf test is successful

现在编辑 /etc/php-fpm.d/www.conf文件，将运行php-fpm进程的用户改为“www”，输入

# vi /etc/php-fpm.d/www.conf

找到“ group of processes”，编辑成下面的样子：

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = www
; RPM: Keep a group allowed to write in log dir.
group = www

最后重启nginx

# /etc/init.d/nginx restart
# /etc/init.d/php-fpm restart
