Zimbra是一款受欢迎的开源邮件解决方案，专为小型企业而设计。
有一种商业产品，我们可以想要额外的功能。
在本教程中，我们将讨论如何在CentOS 8和RHEL 8 Linux服务器上安装配置Zimbra Mail Server。

Zimbra Mail和Collaboration Server的主要组成部分是：Zimbra Core：这些是基本的库，实用程序，监控工具和基本配置文件.zimbra LDAP：这具有OpenLDAP LDAP目录服务器，为用户和其他Zimbra提供身份验证和配置存储Components.zimbra MTA(邮件路由服务器)：具有通过SMTP接收电子邮件的Postfix邮件传输代理(MTA)，并使用本地邮件传输协议(LMTP)将每个消息路由到适当的Zimbra邮箱服务器。
它还包括防我将毒和反垃圾邮件组件.Zimbra Store(Zimbra Server)：邮箱服务器包括服务器上邮箱的数据存储，消息存储和索引存储。
当邮件到达时，Zimbra Server计划一个线程在索引Store.zimbra-snmp中将索引索引：这是用于监控的可选组件，它在每个服务器上运行(Zimbra Server，Zimbra LDAP，Zimbra MTA)。
Swatch用于观看Syslog输出以生成SNMP Traps.zimbra Logger：这是邮箱服务器的可选组件。
它为Syslog聚合，报告和消息跟踪安装工具。
消息跟踪功能需要这一点。

请参阅下面的系统架构，了解所有组件如何运行，以提供协作套件。

在CentOS 8 | rhel 8上安装Zimbra Mail Server

撰写本文的文章，最新的Zimbra Collaboration Suite Release是版本9，但尚未提供开源提供。
这是Zimbra Mail Server我们将在CentOS 8中安装| RHEL 8服务器。
按照以下步骤在CentOS 8/Rhel 8 Linux系统上安装和配置Zimbra Mail Server。

此安装的最低系统要求是：内存：> = 8GBVCPU：> = 4disk：/Opt> 10GB - 建议将/opt/Zimbra作为单独的隔板..对于MX配置的DNS条目，例如MAX的FQDN。
onitoad.comdns为mx条目的记录

这就是我在服务器上的内容：

$free -h
              total        used        free      shared  buff/cache   available
Mem:           15Gi       169Mi        14Gi        16Mi       206Mi        14Gi
Swap:            0B          0B          0B
$df -hT /opt
Filesystem     Type  Size  Used Avail Use% Mounted on
/dev/sda1      ext4  151G 1020M  143G   1% /

第1步：更新系统，安装依赖项和配置NTP

我们始终确保系统更新到最新的可用操作系统版本。

sudo dnf -y update

安装少数基本依赖项。

sudo dnf -y install epel-release dnf-utils
sudo dnf config-manager --enable PowerTools
sudo dnf -y install bash-completion vim curl wget unzip openssh-clients telnet net-tools sysstat perl-core libaio nmap-ncat libstdc++.so.6 bind-utils tar

设置服务器主机名以匹配Mail Server DNS名称：

sudo hostnamectl set-hostname mail.theitroad.com --static

还配置正确的时区和NTP。

sudo dnf -y install chrony
sudo timedatectl set-timezone Africa/Nairobi
sudo systemctl enable --now chronyd
sudo chronyc sources

确认时间已正确设置。

$timedatectl
               Local time: Sun 2017-07-05 14:47:26 EAT
           Universal time: Sun 2017-07-05 11:47:26 UTC
                 RTC time: Sun 2017-07-05 11:47:25
                Time zone: Africa/Nairobi (EAT, +0300)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

执行系统重新启动以确保服务器可以在升级后重新启动。

sudo systemctl reboot

第2步：配置DNS条目。

我们需要设置两个DNS记录.AN邮件serveran mx记录的记录

这些是我将为我的Zimbra服务器设置的值

mail.theitroad.com A 95.217.220.167
theitroad.com MX mail.theitroad.com
mail.theitroad.com MX mail.theitroad.com

我的DNS提供商是CloudFlare。
请咨询DNS提供商如何配置A和MX记录。

设置记录：

为主域设置MX记录。

还为邮件服务器设置MX记录。

仅需几分钟才能传播，然后验证Zimbra Server命令行上的设置。

$dig A mail.theitroad.com +short
95.217.220.155
$dig MX theitroad.com +short
0 mail.theitroad.com.
$dig MX mail.theitroad.com +short
0 mail.theitroad.com.

第3步：下载Zimbra Collaboration软件

Zimbra Collaboration Suite有两种版本：社区版 - 开放的Sourcenetwork版 - 额外的商业功能

在本教程中，我们将在CentOS 8上安装Zimbra的开源版本| Rhel 8 Linux服务器。

wget https://files.zimbra.com/downloads/8.8.15_GA/zcs-8.8.15_GA_3953.RHEL8_64.20170629025823.tgz

提取文件：

tar xvf zcs-8.8.15_GA_3953.RHEL8_64.20170629025823.tgz

第4步：在CentOS 8上安装Zimbra Collaboration Suite

将服务器IP和DNS名称添加到/etc/hosts文件。

$sudo vim /etc/hosts
95.217.220.155 mail.theitroad.com

确保正确设置的区域设置 - 我的英语和UTF-8：

sudo localectl set-locale LANG=en_US.UTF-8
sudo localectl set-locale LANGUAGE=en_US
echo "export LC_ALL=en_US.UTF-8" >>~/.bashrc
logout

将保存ZCS归档Tar文件保存的目录登录返回Zimbra Server和CD。

cd zcs-8.8.15_GA_3953.RHEL8_64.20170629025823

在我们看到的目录中：Readme.txt - Readme FileInstall.sh - 安装installData/- 包含安装数据库/ - 包含zcs rpmsdocs/- 更多文档

我们将通过运行install.sh脚本开始安装。

sudo ./install.sh

1.执行"y"以接受许可条款并开始安装。

步骤5：配置SSL证书

建议使用经过认证的CA或者免费允许的SSL证书或者获取允许的证书。
结帐我们下面的教程以进行安装。

使用Let的Secure Zimbra Server进行加密SSL证书

第6步：访问Zimbra Admin Dashboard

如果我们有活动防火墙，请在"开放端口"中查看我们的教程：

Zimbra防火墙配置与UFW和FireWalld

现在我们在CentOS 8上安装Zimbra | Rhel 8完成让我们打开管理控制台https：//ip-addres | hostname：7071

使用前面配置的用户名管理员和密码登录。

确认所有Zimbra服务在"监视器"部分下处于运行状态。
