Nginx

Nginx多項目部署

系統學習推薦https://mp.weixin.qq.com/s/hafErlto-1N6ypYfOVIGBQ

1. 環境：阿里雲服務器
2. 添加域名映射
   在阿里雲中添加多個主機記錄project1，project2等，然后去ping一個project1.qifengle1412.cn看下能否ping通
3. 啟動多個項目

   upstream blog {
   server 127.0.0.1:端口號;
   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. 報nginx: [emerg] host not found in upstream "xx.cn"錯誤
   

   nginx配置語法上沒有錯誤的,只是系統無法解析這個域名,所以報錯.
   解決辦法就是添加dns到/etc/resolv.conf 或者是/etc/hosts,讓其能夠解析到IP。具體步驟如下：
   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
   

   檢查配置是否有誤 
   sudo nginx -t  
   重載 Nginx 配置
   sudo nginx -s reload
