一、安装acme脚本
curl  https://get.acme.sh | sh

 DNS方式
 
 acme.sh --issue -d *.clsn.io -d clsn.io --dns --yes-I-know-dns-manual-mode-enough-go-ahead-please

 dns添加2条txt记录
 第二次申请证书
 acme.sh --renew  -d *.clsn.io -d clsn.io --dns --yes-I-know-dns-manual-mode-enough-go-ahead-please
 nginx 安装到指定目录中把证书
acme.sh  --installcert  -d  kuailaizhiying.com \
 --key-file   /etc/nginx/ssl/kuailaizhiying.com.key \
 --fullchain-file /etc/nginx/ssl/fullchain.cer \
 --reloadcmd  "service nginx force-reload"
 
yum install epel-release -y
yum install nginx -y


server {
        listen 443 ssl;
        server_name kuailaizhiying.com;

        #ssl on;
        index index.html index.htm;
        ssl_certificate  /etc/nginx/ssl/fullchain.cer;
        ssl_certificate_key  /etc/nginx/ssl/kuailaizhiying.com.key;
        ssl_session_timeout 5m;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;

       location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }
    }
