查看“最简单的upstream”的源代码




== pre: ==

现在的php哥 厉害了word的哥 居然叫帮忙搞负载均衡什么的，我和我的小伴伴都惊呆了，看来我们运维要下岗了呢！ 但是也只好百忙之中抽空帮忙写个最简单的教程！ 自己看吧 我只能帮忙到这里，毕竟这东西还是比较偏向运维的，哥是建议程序哥好好学程序，运维哥好好搞运维! &nbsp;所谓术业有专攻！

== 角色及IP ==

entry 192.168.1.8

server1 192.168.1.11<br/> server2 192.168.1.12

&nbsp;

== 1. 在入口节点下添加upstream节点相关信息 ==
<pre>upstream yag.com {
&nbsp; &nbsp; &nbsp; &nbsp;ip_hash;
&nbsp; &nbsp; &nbsp; &nbsp;server 192.168.1.11:80;
&nbsp; &nbsp; &nbsp; &nbsp;server 192.168.1.12:80;
}

server{&nbsp;
&nbsp; &nbsp; listen 80;&nbsp;
&nbsp; &nbsp; server_name yag.com;&nbsp;
&nbsp; &nbsp; location / {&nbsp;
&nbsp; &nbsp; &nbsp; &nbsp; proxy_pass &nbsp; &nbsp; &nbsp; &nbsp; http://yag.com;&nbsp;
&nbsp; &nbsp; &nbsp; &nbsp; proxy_set_header &nbsp; Host &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $host;&nbsp;
&nbsp; &nbsp; &nbsp; &nbsp; proxy_set_header &nbsp; X-Real-IP &nbsp; &nbsp; &nbsp; &nbsp;$remote_addr;&nbsp;
&nbsp; &nbsp; &nbsp; &nbsp; proxy_set_header &nbsp; X-Forwarded-For &nbsp;$proxy_add_x_forwarded_for;&nbsp;
&nbsp; &nbsp; }&nbsp;
}</pre>

== 2.nginx1 nginx2 ==

服务器nginx.conf设置<br/> 打开nginx.config，在http段加入以下代码 #这些只是举例个格式而已记得自己改
<pre>server{&nbsp;
&nbsp; &nbsp; listen 80;&nbsp;
&nbsp; &nbsp; server_name yag.com;&nbsp;
&nbsp; &nbsp; index index.html;&nbsp;
&nbsp; &nbsp; root /data/www;&nbsp;
}</pre>

<br/> 保存重启nginx
