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
