关于搭建一台负载均衡lb01机器

1.在web01和wenb02两台页面上搭建新的业务

键入网站：www.static.com
[web01]192.168.10.100
web01....
[web02]:19.168.10.110
web02....

2.配置static.conf界面

vim /etc/nginx/conf.d/static.conf

server {
        listen 80;
        server_name www.static.com;

        location / {
        root /code/test;
        index index.html;
        }

}

3.[lb01]上的配置

IP:192.168.10.130

1.安装nginx服务
2.配置反向代理服务
3.为负载均衡业务写配置文件
[root@lb01 nginx]# ls
conf.d  fastcgi_params  mime.types  modules  nginx.conf  proxy_params  scgi_params  uwsgi_params
[root@lb01 nginx]# cd conf.d/
[root@lb01 conf.d]# cat static.conf
upstream webs {
    server 192.168.10.100;
    server 192.168.10.110;
}
server {
    listen 80;
    server_name www.static.com;

    location / {
        proxy_pass http://webs;
        include proxy_params;
    }
}
[root@lb01 conf.d]# cd ..
[root@lb01 nginx]# cat proxy_params
proxy_set_header Host $http_host;
proxy_http_version 1.1;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_connect_timeout 30;
proxy_send_timeout 60;
proxy_read_timeout 60;

proxy_buffering on;
proxy_buffer_size 32k;
proxy_buffers 4 128k;

4.重启nginx生效

客户端（浏览器/测试机）需要将域名 [www.static.com](https://www.static.com) 解析到负载均衡这台机器的外网/访问 IP（通过本地 hosts 文件绑定或公共 DNS 解析），而不是直接解析到后端的 192.168.10.130。
