云服务器搭建zimbra邮箱、配置证书

如果使用云服务器搭建邮箱服务器的话，根据相关规定。需要申请开通25端口，阿里云管控很严格，所以我使用的是自己的IDC机房服务器搭建，如果使用电信的网络需要申请开通25端口

1、关闭防火墙

2、关闭selinux

3、内网IP ：192.168.2.222 公网IP 221.12.155.245

开始安装

yum -y update

安装zimbra所需要的包和库

yum -y install perl perl-core nmap sudo libidn gmp libaio libstdc++ unzip sysstat sqlite nc

关闭安装的MTA服务

systemctl stop postfix.service
systemctl disable postfix.service

安装bind

yum -y install bind bind-utils

修改主机名

修改 /etc/hosts

修改/etc/resolv.conf

chown -R named.named /var/named/

修改 /etc/named.conf

配置证书：

安装使用阿里云免费ssl证书脚本

https://www.itgeeker.net/zimbra-8-x安装使用阿里云免费ssl证书脚本/

首先当然要去阿里云申请的ssl证书下载其他类型证书，解压缩后有两个文件上传到相应目录，这里是/opt/zimbra/ssl/aliyunssl/，文件名类似18131-domain.key和.pem

对比Let’s Encrypt和Wosign的证书，这里会涉及到转换阿里云的RSA密钥到PKCS#8的格式，两者的区别，在于开头和结尾的内容。zimbra是不能验证RSA秘钥的

我们可以通过openssl命令把阿里云的私钥转成zimbra能接受的格式。

openssl pkcs8 -topk8 -inform PEM -in 18131XXXXXXXXX.key -outform PEM -nocrypt -out privkey.pem

完整脚本如下：

#!/bin/bash

# Note: create by itgeeker

domain=mail.itgeeker.net

su - zimbra -c 'zmproxyctl stop'

su - zimbra -c 'zmmailboxdctl stop'

mkdir /opt/zimbra/ssl/aliyunssl/

echo "up load aliyun ssl other to this folder first !!!!!!!"

cd /opt/zimbra/ssl/aliyunssl/

openssl pkcs8 -topk8 -inform PEM -in 18131XXXXXXXXX.key -outform PEM -nocrypt -out privkey.pem

mv 1813131_mail.geekerconsulting.com.pem cert.pem

chown zimbra:zimbra /opt/zimbra/ssl/aliyunssl/*

su - zimbra -c 'cd /opt/zimbra/ssl/aliyunssl/ && /opt/zimbra/bin/zmcertmgr verifycrt comm privkey.pem cert.pem '

echo "Backup Zimbra SSL directory"

cp -a /opt/zimbra/ssl/zimbra /opt/zimbra/ssl/zimbra.$(date "+%Y%m%d")

echo "Copy the private key under Zimbra SSL path"

cp /opt/zimbra/ssl/aliyunssl/privkey.pem /opt/zimbra/ssl/zimbra/commercial/commercial.key

echo "Final SSL deployment"

su - zimbra  -c 'cd /opt/zimbra/ssl/aliyunssl/ /opt/zimbra/bin/zmcertmgr deploycrt comm cert.pem'

echo "restart zimbra"

su - zimbra -c 'zmcontrol restart'

gist link:

https://gist.github.com/alanljj/2f90ca543dc2f2e45319ac13c30bbf72

验证zimbra ssl证书命令：

su - zimbra -c '/opt/zimbra/bin/zmcertmgr viewdeployedcrt'

更新

通过上面的方法虽然没有提示任何错误，但可能无法更新证书，使用验证命令，仍然会显示老的证书。那么就需要以下的复杂流程了。

zimbra证书的三个文件，目录/opt/zimbra/ssl/zimbra/commercial/：

commercial_ca.crt
commercial.crt
commercial.key

zimbra ssl证书制作方法：

commercial_ca.crt – 阿里云下载证书1813131_domain.pem的第二部分，也就是第二个—–BEGIN CERTIFICATE—–到—–END CERTIFICATE—– 也就是中级证书(mid-digicert-ca) + 根证书（root-digiert-ca）

两者中间不能有空行

阿里云免费ssl的根证书分享，不同发证机构根证书会有所不同：

-----BEGIN CERTIFICATE-----

-----END CERTIFICATE-----

commercial.crt – 1813131_domain.pem的第一部分，也就是第一个—–BEGIN CERTIFICATE—–到—–END CERTIFICATE—–部分。

commercial.key – 就是1813131_domain.key，用上面的RSA密钥到PKCS#8 转换方法先转换，然后改名字就可以了。

开始部署

上传三个文件到/opt/zimbra/ssl/zimbra/commercial/目录，上传前检查、检查、再检查是否已经正确，如果老的文件已存在，先删除老的三个文件（技术奇客有碰到未删除，生成的文件格式不对导致无法更新ssl证书的情况）

验证证书。进入/opt/zimbra/ssl/zimbra/commercial/目录后，使用zimbra用户执行：

/opt/zimbra/common/bin/openssl verify -CAfile commercial_ca.crt commercial.crt

部署证书。使用zimbra用户执行：

/opt/zimbra/bin/zmcertmgr deploycrt comm commercial.crt commercial_ca.crt

重启zimbra服务。

su - zimbra -c 'zmcontrol restart'

查看新证书。

su - zimbra -c '/opt/zimbra/bin/zmcertmgr viewdeployedcrt'
