HTTPS实现及自动续期

安装certbot

进行安装目录，如：/data1/server （根据实际情况输入）
git clone https://github.com/certbot/certbot

配置nginx

见下面的完整示例
注意首次配置时需要只开放80端口，完成证书申请后再配置443端口

申请证书

支持一次性申请多个域名（多个域名共用一份证书）

示例

/data1/server/certbot/letsencrypt-auto --no-self-upgrade certonly  --webroot -w /data1/webroot/gitlab/certbot/hostname.com  -d qy.xzdjjd.com  -d wx.xzdjjd.com  -d sp.xzdjjd.com  -d svc.xzdjjd.com

成功后证书一般会位于该目录 /etc/letsencrypt/live/

更新nginx，强制走https

见下面完整示例
更新后重启nginx，并访问网址，检查是https是否正常

自动续期

通过crontab添加定时更新任务

crontab -e

0 3 * * * /data1/tools/certbot/letsencrypt-auto renew --no-self-upgrade --post-hook "/data1/cron/certbot_renew.sh" > /dev/null 2>&1 &

其中certbot_renew.sh为更新证书后，重启nginx让证书生效的脚本，如：

#!/bin/bash
set -xe
#source /etc/profile

# 每天定期重启Nginx，避免ssl证书过期
# 只有测试通过才重启nginx
/data1/server/nginx/1.15.7/bin/sbin/nginx -t 
if [ $? -eq 0 ]; then 
    # 重新启动nginx
    /data1/server/nginx/1.15.7/bin/sbin/nginx -s reload
fi

exit $?

加密算法（ssl_ciphers）根据实际情况配置，本示例中的算法对CPU消耗较高
