nginx 一端口多网站代理

Posted 2021-08-14 长虹剑

起因：服务器只留了一个端口可以访问，想搭建多个网站

nginx配置多个域名使用同一个端口 # 该方法没有仔细尝试，不知道适不适合我的情况

Nginx代理proxy pass配置去除前缀

安装配置

conda install -c anaconda nginx
nginx -t
# anaconda3/etc/nginx/nginx.conf

#apt-get install psmisc
killall nginx
nginx
# 或者使用 service nginx xxx

killall nginx && nginx

proxy_set_header: 给上游服务器发的
add_header: 给浏览器看的

rewrite 修改请求url，然后决定干什么
具体 last: 再次location; break: 本次直接往下走; redirect, permanent 重定向.
但是后两者会导致响应的location改变，最终自动加上了端口
