springboot+nginx+https+linux实现负载均衡加域名访问简单测试

1. 把springboot项目打包成三个jar包，并指定端口为

   14341，14342，14343

2. 下载腾讯云免费ssl证书，解压后会出现如下图文件夹

   

3. 把nginx文件夹下的 .crt 和 .key文件复制到服务器，例如复制到

   /home/ssl/xxx.crt
   /home/ssl/xxx.key

4. 安装好nginx默认配置文件在

   /usr/local/nginx/conf/nginx.conf

5. 修改nginx.conf配置文件实现https+负载均衡的简单测试（此测试是在一台服务器上面进行）

   worker_processes  1;
   
   events {
       worker_connections  1024;
   }
   
   http {
       include       mime.types;
       default_type  application/octet-stream;
   
       sendfile        on;
       keepalive_timeout  65;
   
       upstream paint {
           server 127.0.0.1:14341 weight=2;
   	    server 127.0.0.1:14342 weight=1;
   	    server 127.0.0.1:14343 weight=1;
       }
   
       server {
           listen       443 ssl;
           server_name  www.xxx.com xxx.com;
           ssl_certificate /home/ssl/xxx.crt;
           ssl_certificate_key /home/ssl/xxx.key;
           ssl_session_timeout 5m;
           ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
           ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
           ssl_prefer_server_ciphers on;
           location / {
               proxy_pass http://paint;
           }
       }
   
       server {
           listen       80;
           server_name  www.xxx.com xxx.com;
           rewrite  ^(.*)$  https://${server_name}$1  permanent;
       }
   }

6. 以上nginx.conf配置文件即可实现，理论上来说weight设置的数值越大，访问到的机率就会越大
7. 在linux上后台运行第一步准备的jar包

   nohup java -jar xx01-0.0.1-SNAPSHOT.jar >/home/log/logs1.txt &
   nohup java -jar xx02-0.0.1-SNAPSHOT.jar >/home/log/logs2.txt &
   nohup java -jar xx03-0.0.1-SNAPSHOT.jar >/home/log/logs3.txt &

8. 查看后台运行的任务
