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

把springboot项目打包成三个jar包，并指定端口为
```
14341，14342，14343
```
下载腾讯云免费ssl证书，解压后会出现如下图文件夹
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
```
安装好nginx默认配置文件在
```
/usr/local/nginx/conf/nginx.conf
```

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;

    }

}

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

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 &

查看后台运行的任务
