Nginx-SLB部署

准备工作：

LB01：172.14.106.15

web01 ：172.14.106.19

web02:172.14.106.23

安装nginx
```
yum install -y nginx
```

配置代理服务器LB01

[root@172-16-104-15 conf.d]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.104.15  hongmi.slb.com
[root@172-16-104-15 conf.d]# pwd
/etc/nginx/conf.d
[root@172-16-104-15 conf.d]# cat slb.conf 
upstream slb01 {
       server 172.16.104.19;
 server 172.16.104.23;
}
server {
listen 80;
server_name hongmi.slb.com;

location / {
proxy_pass   http://slb01;
include /etc/nginx/proxy_params;
}
}
[root@172-16-104-15 nginx]# cat nginx.conf

user  root;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;

events {
   worker_connections  1024;
}

http {
   include       /etc/nginx/mime.types;
   default_type  application/octet-stream;

   log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                     '$status $body_bytes_sent "$http_referer" '
                     '"$http_user_agent" "$http_x_forwarded_for"';

   access_log  /var/log/nginx/access.log  main;

   sendfile        on;
   #tcp_nopush     on;

   keepalive_timeout  65;

   gzip  on;
   include /etc/nginx/conf.d/*.conf;
}

配置后端服务器web01

[root@172-16-104-180 conf.d]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.104.15  hongmi.slb.com    #本地域名解析
[root@172-16-104-180 conf.d]# cat xiaoniaoff.conf 
server {
   listen       80;
   server_name  hongmi.slb.com;

   location / {
       root   /code/xiaoniaofeifei;    #访问小鸟飞飞
       index  index.html index.htm;
   }

}
[root@172-16-104-180 conf.d]# pwd
/etc/nginx/conf.d
[root@172-16-104-180 conf.d]# ls /code/xiaoniaofeifei/    #小鸟飞飞的项目位置
