nginx,docker反向代理

proxy_busy_buffers_size 64k; #高负荷下缓冲大小（proxy_buffers*2）
proxy_temp_file_write_size 64k; #设定缓存文件夹大小，大于这个值，将从upstream服务器传递请求，而不缓冲到磁盘
proxy_ignore_client_abort on; #不允许代理端主动关闭连接
upstream exchange {
#ip_hash;
server 192.168.10.54:8080 weight=1 max_fails=2 fail_timeout=10s;
server 192.168.10.57:8080 weight=1 max_fails=2 fail_timeout=10s;
}

upstream filter {

server 192.168.10.54:8056 weight=1 max_fails=2 fail_timeout=10s;
server 192.168.10.57:8056 weight=1 max_fails=2 fail_timeout=10s;
}

upstream message {

}

}

server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}

2.

[root@javanginx ~]# cat /etc/nginx/conf.d/exchange.conf
server{
listen 8080;
server_name 192.168.10.53;
location / {
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;
proxy_pass http://exchange;
}
}

完成！
