看见 hostloc 上有人求黑群怎么自动更新 ssl 证书

[yinaqu]

没有 hostloc 帐号，所以不能回复，贴上自己写的自动更新 ssl 证书脚本，以便帮助有需要的人。 ps：

1. 这个脚本工作于我的 dsm6.2 ，如果是 dsm7 ，你可能需要更改下证书存放路径和服务重启方式（自己找找相关信息，思路是一样的）
2. 由于运营商封 80 端口，所以不能使用 http challenge ，只能使用 dns challeng 。这个脚本使用的是 acme.sh 的 cloudflare 的 api ，如果要改成其它提供商如阿里云，请参考 acme.sh 相关文档，切换应该也很简单

#!/bin/bash

# Automatically update certs for Synology DSM6
# 1. Migrate your domain to Cloudflare, and create an A type record.
# 2. Generate a token with zone view authority and dns edit authority.
# 3. Install acme.sh on DSM6, no need crontabs: ./acme.sh --install --force -m [email protected]
# 4. Put this script into user defined task scheduler, executes per one month or two.
# 5. Make sure this script will be exectuted once immediately by your schedule task, or just execute it once mannually.

# Modify these as your own.

你自己代码里密钥没删

[Masoud2023]

10 分钟还没过，赶紧编辑掉，过了就去后台重新生成

[yinaqu]

@Masoud2023 已删。cf 的密钥也删了，谢谢

用 npm ，方便点，也自带续费

[Junichi]

https://github.com/andyzhshg/syno-acme

黑裙 7.2 一直在用这个续签证书

[skiy]

用 acme.sh 别名方式续签，域名在不同的 DNS 都可以集中到一个
https://github.com/acmesh-official/acme.sh/wiki/DNS-alias-mode#1-first-set-domain-cname

用 acme.sh 自带的 --install-cert 命令行，可以直接安装到不同的目录
用 acme.sh 自带的 --reloadcmd 命令行，可以在证书更新后执行相关命令或脚本（只需要封装一下 restart_services 这个就行）
https://github.com/acmesh-official/acme.sh/wiki/Using-pre-hook-post-hook-renew-hook-reloadcmd
```bash
# 比如
acme.sh --install-cert --ecc -d a.com --key-file /usr/local/nginx/conf/ssl/a.com.key --fullchain-file /usr/local/nginx/conf/ssl/a.com.fullchain.cer --reloadcmd "systemctl reload nginx"
```

还可以加个续签通知：
https://github.com/acmesh-official/acme.sh/wiki/notify

[emberzhang]

https://github.com/certd/certd 最近用这个，感觉还挺方便

[yinaqu]

@Junichi 这个写的还不错。他只重启了 nginx 和 apache ，我倒不是很清楚是不是只重启 apache 就可以把 webdav 和 sync 什么的全部重启了

[yinaqu]

@skiy 这个`install-cert`貌似并不能安装到多个目录去吧，reloadcmd 就是个钩子而已，没有把我的重启命令那么长一截放他钩子里

[yinaqu]

@emberzhang 好东西， 我以前也是没怎么去发掘这些就自己写了个，这个支持自定义服务重启吗

[emberzhang]

@yinaqu 每个 “上传证书到主机” 任务后面增加一个“执行远程主机脚本命令”就行了
