准备三台虚拟机来做这个实验:
PA 负载均衡服务器 www.mydomain.com
PA1 192.168.2.3 web服务器
PA2 192.168.2.4 web服务器1、导入外部软件库
rpm -Uvh http://dl.iuscommunity.org/pub/ius/stable/Redhat/6/i386/epel-release-6-5.noarch.rpm rpm -Uvh http://dl.iuscommunity.org/pub/ius/stable/Redhat/6/i386/ius-release-1.0-10.ius.el6.noarch.rpm rpm -Uvh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm 以下添加注释 mirrorlist=http://dmirr.iuscommunity.org/mirrorlist?repo=ius-el6&arch=$basearch 以下删除注释 #baseurl=http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/$basearch
yum install nginx
1. 装完之后哈,我们先找到 PA 的nginx.conf配置文件: 在http段加入以下代码:
upstream servers.mydomain.com { server 192.168.2.3:80; server 192.168.2.4:80; }servers.mydomain.com随便取的。
那么PA的server配置如下: 在http段加入以下代码:
server{ listen 80; server_name www.mydomain.com; location / { proxy_pass http://servers.mydomain.com; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } }那么PA1、PA2 的配置如下:
server{ listen 80; server_name www.mydomain.com; index index.html; root /data/htdocs/www; }用其它端口行不行啊,当然也是可以的,假设PA的nginx.conf配置文件:
upstream servers2.mydomain.com { server 192.168.2.3:8080; server 192.168.2.4:8081; } server{ listen 80; server_name www.mydomain.com; location / { proxy_pass http://servers2.mydomain.com; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } }那么PA1的配置如下:
server{ listen 8080; server_name www.mydomain.com; index index.html; root /data/htdocs/www; }
PA2配置:
server{ listen 8081; server_name www.mydomain.com; index index.html; root /data/htdocs/www; } 配置完成
