Zimbra SSL证书一键安装和续期脚本
上篇我们讲述了使用 Let's Encrypt 为Zimbra 安装可信任的SSL证书,但是是手动方式,由于Let's Encrypt 证书有效期只有3个月,所以每3个月需要再次进行续期,每次都手动做一下的话很麻烦,于是我这里把步骤都整理成一个脚本,当需要续期的时候直接运行脚本即可,同时也可以用于首次安装证书。
说是一键安装脚本,实际上由于生成证书的时候有交互,且首次安装证书与续期的时候交互不一样,所以脚本里不好控制,就没有实现完全的一键安装,但已经大大的节省了时间成本,每3个月运行一次,一年就运行4次,有何不可呢。
系统环境:CentOS7.7 64位
Zimbra版本:Zimbra-8.8.15
说明:本脚本仅支持 Zimbra8.7及以上版本,Zimbra8.6及以下版本请访问zimbra wiki原文进行操作:https://wiki.zimbra.com/wiki/Installing_a_LetsEncrypt_SSL_Certificate
脚本内容如下:
cat zimbra-ssl-install-and-renew.sh
