centos7使用let’s Encrypt配置nginx的ht

1.安装certbot##

yum install certbot

2.生成证书##

cd letsencrypt
./letsencrypt-auto certonly --standalone --email 邮箱@***.com -d 域名.com -d *.域名.com
执行证书命令时先关闭nginx

3.添加txt解析##

按照提示，前往域名后台添加对应的DNS TXT记录，不要着急按回车！！！

成功后证书存放在/etc/letsencrypt/live/xxx.com/里面
cert.pem 服务器证书文件

privkey.pem 服务器证书的私钥

chain.pem 除服务器证书外，浏览器解析所需的其他全部证书

fullchain.pem 服务器证书的全部证书链文件

4.配置nginx 代理tomcat##

http {
include mime.types;
default_type application/octet-stream;

#log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
#                  '$status $body_bytes_sent "$http_referer" '
#                  '"$http_user_agent" "$http_x_forwarded_for"';

#access_log  logs/access.log  main;

sendfile        on;
#tcp_nopush     on;

#keepalive_timeout  0;
keepalive_timeout  65;

#gzip  on;

server {
    listen       80;
    server_name  ****.com;
    rewrite ^ https://$http_host$request_uri? permanent;    # force redirect http to https
    return 301 https://$http_host$request_uri;
}

#    }
#}

    server_name *****.com;
    ssl_certificate /etc/letsencrypt/live/****.com/fullchain.pem;
