Ubuntu搭建Nginx反向代理服务器

Ubuntu搭建Nginx反向代理服务器

安装

sudo apt-get install nginx

验证是否安装成功

nginx -v

---

配置

nginx配置文件位置

cd /etc/nginx/conf.d/

编辑配置文件

upstream ssrtest {
    server 127.0.0.1;
}
server {
    listen 11334;
    server_name 111.112.133.144;

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Nginx-Proxy true;
        proxy_pass http://ssrtest;
        proxy_redirect off;
    }
}

以上配置实现的功能是将127.0.0.1的80端口映射到了111.112.133.144主机的11334端口上（已成功验证）

测试Nginx配置文件是否正确

nginx -t

Nginx相关信息

默认安装位置：
/usr/sbin/nginx：主程序
/etc/nginx：存放配置文件
/usr/share/nginx：存放静态文件
/var/log/nginx：存放日志

Nginx常用命令

nginx常用命令 
    nginx -c /usr/local/nginx/conf/nginx.conf  启动nginx(windows下start nginx); 
    nginx -s quit       停止ngix 
    nginx -s reload     重新载入nginx(当配置信息发生修改时) 
    nginx -s reopen     打开日志文件 
    nginx -v            查看版本 
    nginx -t            查看nginx的配置文件的目录 
    nginx -h            查看帮助信息 

Nginx默认端口修改

Nginx默认工作在80端口上，这个和上面的修改反响代理的配置文件之间是没有影响的

Nginx默认端口生效的原由

查看配置文件cat /etc/nginx/nginx.conf

上面的配置文件中包含include /etc/nginx/sites-enabled/*; ，跟进这个文件cat /etc/nginx/sites-enabled/default

显然的在这份配置文件中我们能够找到默认的Nginx是监听80端口的，因此修改之前的反向代理的配置文件的时候，只填写127.0.0.1,便可以访问到Nginx的初始欢迎页面
