一个快速获取/更新 Let's encrypt 证书的 shell script
|
|
------------
|
|
|
|
调用 acme_tiny.py 认证、获取、更新证书，不需要额外的依赖。
|
|
|
|
**下载到本地**
|
|
```
|
|
wget https://raw.githubusercontent.com/xdtianyu/scripts/master/lets-encrypt/letsencrypt.conf
|
|
wget https://raw.githubusercontent.com/xdtianyu/scripts/master/lets-encrypt/letsencrypt.sh
|
|
chmod +x letsencrypt.sh
|
|
```
|
|
**配置文件**
|
|
只需要修改 DOMAIN_KEY DOMAIN_DIR DOMAINS 为你自己的信息
|
|
|
|
```
|
|
ACCOUNT_KEY="letsencrypt-account.key"
|
|
DOMAIN_KEY="example.com.key"
|
|
DOMAIN_DIR="/var/www/example.com"
|
|
DOMAINS="DNS:example.com,DNS:whatever.example.com"
|
|
```
|
|
|
|
执行过程中会自动生成需要的 key 文件。
|
|
|
|
**运行**
|
|
|
|
```
|
|
./letsencrypt.sh letsencrypt.conf
|
|
```
|
|
|
|
**注意**
|
|
需要已经绑定域名到 `/var/www/example.com` 目录，即通过 `http://example.com` `http://whatever.example.com` 可以访问到 `/var/www/example.com` 目录，用于域名的验证
|
|
|
|
**cron 定时任务**
|
|
|
|
每个月自动更新一次证书，可以在脚本最后加入 service nginx reload等重新加载服务。
|
|
|
|
```
|
|
0 0 1 * * /etc/nginx/certs/letsencrypt.sh /etc/nginx/certs/letsencrypt.conf >> /var/log/lets-encrypt.log 2>&1
|
|
```
