Nginx多项目部署

系统学习推荐https://mp.weixin.qq.com/s/hafErlto-1N6ypYfOVIGBQ

1. 环境：阿里云服务器
2. 添加域名映射
   在阿里云中添加多个主机记录project1，project2等，然后去ping一个project1.qifengle1412.cn看下能否ping通
3. 启动多个项目

   upstream blog {
   server 127.0.0.1:端口号;
   keepalive 64;
   }

   server {
   listen 80;
   server_name a.demo.com;
   rewrite ^(.*)$ https://$host$1 permanent;
   }

   server {
   listen 443 ssl;
   server_name a.demo.com;

   ssl_certificate /home/ssl/demo.pem;
   ssl_certificate_key /home/ssl/demo.key;
   ssl_session_timeout 5m;

   location / {
   proxy_http_version 1.1;
   proxy_set_header Upgrade $http_upgrade;
   proxy_set_header Connection "upgrade";
   proxy_set_header Host $host;
   proxy_set_header X-Nginx-Proxy true;
   proxy_cache_bypass $http_upgrade;
   proxy_set_header X-Real-IP $remote_addr;
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   proxy_pass http://a; #反向代理
   }

   }

4. 报nginx: [emerg] host not found in upstream "xx.cn"错误
   

   nginx配置语法上没有错误的,只是系统无法解析这个域名,所以报错.
   解决办法就是添加dns到/etc/resolv.conf 或者是/etc/hosts,让其能够解析到IP。具体步骤如下：
   vim /etc/hosts
   修改hosts文件，在hosts文件里面加上一句
   127.0.0.1       localhost.localdomain   xx.cn

5. nginx常用命令
   

   检查配置是否有误 
   sudo nginx -t  
   重载 Nginx 配置
   sudo nginx -s reload
