CentOS 7虚拟机下模拟实现nginx负载均衡

以CentOS 7为例,我们模拟实现nginx来处理静态资源，apache来处理php

1.首先我们来安装nginx

  # wget  http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2.建立YUM仓库

# rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm

3.安装nginx

yum install nginx

4.启动nginx并设置为开机启动

nginx    启动nginx      如果机器上面已经安装了apache此次会报错。我们需要修改端口 

systemctl enable nginx    开机启动

5.修改nginx的配置文件，设置一个新端口

        cd /etc/nginx            --进入nginx目录

         vi nginx.conf            --修改配置

  #  include /etc/nginx/conf.d/*.conf;       注释掉此行，为了避免载入conf.d目录下的配置




    server {
    listen 88 ;                              重新设置端口
    # server_name test.com;
    location /
{
  root /usr/share/nginx/html;                默认目录
  index index.html index.htm;                
}
 

location ~ .php$ {                          PHP路由转向规则
        proxy_pass   http://192.168.0.101:80;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ .php$ {                                 PHP处理文件及目录（本机apache）
        root           /var/www/html;
        fastcgi_pass   192.168.0.101:80;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        include        fastcgi_params;
    }

 这样html资源就留在了localhost:88，php资源就转向192.168.0.101
