使用Let's Encrypt + Nginx生成免费HTTPS证书

Let’s Encrypt简介

官网:https://letsencrypt.org/

Let’s Encrypt作为一个公共且免费SSL的项目逐渐被广大用户传播和使用,是由Mozilla、Cisco、Akamai、IdenTrust、EFF等组织人员发起,主要的目的也是为了推进网站从HTTP向HTTPS过度的进程,目前已经有越来越多的商家加入和赞助支持。

certbot简介

官方客户端 CertbotCertBot提供了很多命令来管理证书的获取,更新,与撤销,详情可参阅官网。

操作步骤

1.克隆certbot仓库

sudo git clone 

https://github.com/certbot/certbot/opt/letsencrypt/opt/letsencrypt/letsencrypt-auto

2. Nginx server配置域名验证

location ^~ /.well-known/acme-challenge/ {

     default_type "text/plain";

    root  /opt/JAVA1024/CERT;

}

 

location = /.well-known/acme-challenge/ {

   return 404;

}

  

3.使用certbot生成证书

export DOMAINS="java1024.club,m.java1024.club"export DIR=/opt/JAVA1024/CERT

/opt/letsencrypt/letsencrypt-auto certonly --server https://acme-v01.api.letsencrypt.org/directory -a webroot --webroot-path=$DIR -d $DOMAINS

  

4.使用证书, Nginx server配置

listen 443;#let's encrypt

ssl_certificate /etc/letsencrypt/live/java1024.club/fullchain.pem;

ssl_certificate_key  /etc/letsencrypt/live/java1024.club/privkey.pem;

  

5.创建自动检查更新脚本,并加入crontab

crontab 是用来定期检查证书有效期。

 

#!/bin/sh# This script renews all the Let's Encrypt certificates with a validity < 30 days

if ! /opt/letsencrypt/letsencrypt-auto renew > /var/log/letsencrypt/renew.log 2>&1 ; then

    echo Automated renewal failed:

    cat /var/log/letsencrypt/renew.log

    exit 1fi

nginx -t && nginx -s reload

加入定时任务

sudo crontab -e

@daily /mnt/crontab_scrpit/renew_certs.sh

6.更改域名信息

export DOMAINS="java1024.club,m.java1024.club,java1024.com"

export DIR=/opt/JAVA1024/CERT

/opt/letsencrypt/letsencrypt-auto certonly --server https://acme-v01.api.letsencrypt.org/directory -a webroot --webroot-path=$DIR -d $DOMAINS

7. 重启服务器

nginx -s reload

访问域名,效果展示:
