nginx 反向代理

# 反向代理 Apache

nginx.conf

server
{
            listen       80;
            server_name  www.sui.cn lucky.sui.cn;

   location / {            
            proxy_pass              http://127.0.0.1:8080;              
            proxy_redirect          off;        
            proxy_set_header Host $host;       
            proxy_set_header X-Real-IP $remote_addr;       
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;           
            } 
}

httpd.conf

#在httpd.conf中 添加 (/etc/httpd/conf/httpd.conf)

<virtualhost *:8080>
    ServerName  www.sui.cn
    ServerAlias  www.sui.cn lucky.sui.cn
    DocumentRoot  /www/one
    DirectoryIndex index.php index.html
    <Directory /www/one>
    Options +Includes +FollowSymLinks -Indexes
    AllowOverride All
    Order Deny,Allow
    Allow from All
    </Directory>
</virtualhost>

 

经过域名反向代理:

upstream myapp {
    # server www.sui6666.com:8888 weight=1; # 应用服务器1
    # server 121.65.111.236:8888 weight=3;
     server www.test.com;
}

server
{
            listen       80;
            server_name  sui1.lucky.com;
 
   location / {           
             proxy_pass  http://myapp;
             proxy_set_header Host  www.test.com;       
            }
}

proxy_pass http://www.test.com;

nginx会把 www.test.com;转换成IP, 跟用IP直接访问网站的效果同样. 当网站设置了禁用IP访问或一个IP有多个网站时, 访问就会出错.

这时候就要设置 proxy_set_header的Host:

proxy_set_header Host www.test.com;;

这样才能经过域名解析到具体的网站, nginx反向代理同一ip多nginx反向代理同一ip多个域名，给header加上host就能够了个域名，给header加上host就能够了

 

反向代理gitlab

nginx.conf

 server {
         listen      80;
     
         server_name  git.sui.net;

        location / {
            proxy_pass http://127.0.0.1:8080;
        }

       
    }

gitlab 修改默认ssh端口为2222 ,使用git修改默认的ssh端口号(vim ~/.ssh/config)

        Host git.sui.net
    HostName git.sui.net
    User 28456049@qq.com
    port 2222
    IdentityFile ~/.ssh/git.sui.net_rsa    

 # 反向搭理wss

upstream wss_svr {
server 127.0.0.1:2346 weight=1;  #这里能够是多个服务端IP（分多行），设置权重就能够实现负载均衡了(websocket 服务的端口,swoole,nodejs.go服务的websocket均可以)
