简单配置 nginx 反向代理

# Nginx 域名反向代理配置
# 安装nginx
yum install nginx -y
# 修改配置文件
进入配置文件目录 cd /etc/nginx/conf.d
新建配置文件以.conf结尾 vim test.conf
输入一下内容：
server {
listen 80;
server_name a.domain.com;
access_log /var/node/log/host.access.log main;
location / {
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-Ip $remote_addr;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://192.168.2.2:7789;
# 支持websocket
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
##
proxy_redirect off;
}
}
server_name a.domain.com # 配置二级域名
proxy_pass http://42.159.191.244:7789 # 配置指向web服务
重启 service nginx restart
访问 http://a.domain.com 即可访问到 http://192.168.2.2:7789 服务
如果配置多个代理 即 新建配置文件 test1.conf、test2.conf（必须在/etc/nginx/conf.d 目录下建立）
server {
listen 80;
server_name b.domain.com;
access_log /var/node/log/host.access.log main;
location / {
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-Ip $remote_addr;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://192.168.88.2:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_redirect off;
}
}
输入配置内容 更改 server_name 与 proxy_pass 即可。
