centos6.5 安装nginx
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：
view plaincopy
[*]# 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：
view plaincopy
[*]# 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
注：http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-7.noarch.rpm 该源提示错误请用下面的源进行下载安装 =>http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

如果你想在系统启动时自动运行php-fpm，输入下列命令：
view plaincopy
[*]# 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：
view plaincopy
[*]# 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：
view plaincopy
[*]# /etc/init.d/php-fpm restart
输出样例
view plaincopy
[*]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：
view plaincopy
[*]# vi /etc/nginx/nginx.conf
像下面这样编辑取消注释：
view plaincopy
[*] ...
[*]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
view plaincopy
[*]# /etc/init.d/nginx reload
现在在document root目录下建立下列PHP文件
view plaincopy
[*]# vi /usr/share/nginx/html/info.php
文件内容如下：
view plaincopy
[*]<?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
view plaincopy
[*]# useradd www
创建必要的目录
view plaincopy
[*]# 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
view plaincopy
[*]# cd /etc/nginx/conf.d/
[*]# cp virtual.conf www.conf
输入下面命令打开www.conf文件
view plaincopy
[*]# vi /etc/nginx/conf.d/www.conf
增加以下配置
view plaincopy
[*]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
view plaincopy
[*]# /etc/init.d/nginx configtest
输出样例
view plaincopy
[*]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
view plaincopy
[*]# vi /etc/php-fpm.d/www.conf
找到“group of processes”，编辑成下面的样子：
view plaincopy
[*]; 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
view plaincopy
[*]# /etc/init.d/nginx restart
[*]# /etc/init.d/php-fpm restart
