原文地址：http://www.lifelinux.com/how-to-install-nginx-and-php-fpm-on-centos-6-via-yum/
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
输出样例

如果你想在系统启动时自动运行nginx，输入下列命令：
# chkconfig --level 345 nginx on
第一次启动nginx，输入下列命令：
# /etc/init.d/nginx start
输出样例
Starting nginx: [ OK ]
安装PHP-FPM

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：
<?php
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
