停止服务器上现有的 MTA 服务

默认情况下，CentOS 7 将 Postfix 安装为 MTA（邮件传输代理）。
在继续安装 Zimbra Collaboartion Suite (ZCS) 之前，我们需要禁用它。

停止并禁用 postfix.service。

[root@zimbra-01 ~]# systemctl stop postfix.service
[root@zimbra-01 ~]# systemctl disable postfix.service
Removed symlink /etc/systemd/system/multi-user.target.wants/postfix.service.
[root@zimbra-01 ~]# systemctl mask postfix.service
Created symlink from /etc/systemd/system/postfix.service to /dev/null.

为 Zimbra 邮件服务器安装必备软件包

使用 yum 命令安装所需的软件包。

[root@zimbra-01 ~]# yum install -y libidn gmp perl perl-core ntpl nmap sudo sysstat sqlite libaio libstdc++ wget unzip

在 CentOS 7 上安装 Zimbra 邮件服务器

Zimbra Collaboration Suite 开源版可从 Zimbra 官方下载页面下载。

[root@zimbra-01 ~]# cd /tmp
[root@zimbra-01 tmp]# wget https://files.zimbra.com/downloads/8.8.12_GA/zcs-8.8.12_GA_3794.RHEL7_64.20190329045002.tgz

提取下载的 TAR 文件。

[root@zimbra-01 tmp]# tar xvf zcs-8.8.12_GA_3794.RHEL7_64.20190329045002.tgz

转到 Zimbra Collaboration Suite 安装目录并开始安装。

[root@zimbra-01 tmp]# cd zcs-8.8.12_GA_3794.RHEL7_64.20190329045002/

Zimbra Collaboration Suite 已安装在我们的 CentOS 7 服务器上。

验证 Zimbra 邮件服务器的 DNS 设置

以 root 用户身份使用 ssh 连接 zimbra-01.onitroad.com。

在配置私有邮件服务器之前，必须有一个权威 DNS 服务器。

此 DNS 服务器需要回答 MX（邮件交换）查询，因此应将电子邮件重定向到我们的 Zimbra 邮件服务器。

如果我们有 DNS 服务器，则可以其中添加 MX 和 zimbra-01.onitroad.com 的 A 记录。

为了验证我们是否为 Zimbra 邮件服务器正确配置了 DNS 设置，我们可以使用 dig 命令。

[root@zimbra-01 ~]# dig -t MX onitroad.com
; <<>> DiG 9.9.4-RedHat-9.9.4-74.el7_6.2 <<>> -t MX onitroad.com
;; global options: +cmd
;; Got answer:

;; WHEN: Mon Aug 12 18:02:16 PKT 2019
;; MSG SIZE  rcvd: 96

从上面的输出中，我们可以看到，我们的 Zimbra 邮件服务器的 MX 和 A 记录已正确定义。

除了 DNS 设置之外，我们还需要将其包含在我们的本地 DNS 解析器中。

[root@zimbra-01 ~]# echo "192.168.1.6 zimbra-01.onitroad.com zimbra-01" >> /etc/hosts
在 CentOS 7 上安装 Zimbra 邮件服务器

Zimbra 协作套件 (ZCS) 是一个协作软件套件，包括带有 Web 客户端的邮件和聊天服务器。

Zimbra 有两个版本，一个是 Zimbra 网络版（商业版），另一个是 Zimbra 开源版（社区支持版）。

在本文中，我们将在 CentOS 7 上安装 Zimbra 邮件服务器。
要配置 Zimbra 邮件服务器，我们将安装 Zimbra Collaboration Suite 软件，然后我们将配置 Zimbra 邮件服务器。
我们还将使用 Zimbra Collaboration Suite (ZCS) 配置 XMPP 聊天服务器。

Zimbra Collaboration Suite (ZCS) 是一个大型软件，具有许多特性和功能。

Zimbra 协作套件 - 安装后配置

Zimbra Collaboration Suite 使用禁用密码创建操作系统用户 zimbra。
Zimbra Collaborative Suite 使用 ssh 密钥与该用户连接。
因此，我们需要如下配置 ssh 密钥。

[root@zimbra-01 ~]# sudo -u zimbra -i
[zimbra@zimbra-01 ~]$ zmupdateauthkeys
Updating keys for zimbra-01.onitroad.com
Fetching key for zimbra-01.onitroad.com
Updating keys for zimbra-01.onitroad.com
Updating /opt/zimbra/.ssh/authorized_keys

为了在管理控制台上显示服务器统计信息，必须按如下方式修改 syslog 配置文件。

以 root 用户身份连接并执行以下命令。

[root@zimbra-01 ~]# /opt/zimbra/libexec/zmsyslogsetup
updateSyslog: Updating /etc/rsyslog.conf...done.

启用使用 ClamAV 防病毒软件自动扫描电子邮件附件。

[root@zimbra-01 ~]# su - zimbra
[zimbra@zimbra-01 ~]$ zmprov mcf zimbraAttachmentsScanURL clam://localhost:3310/
[zimbra@zimbra-01 ~]$ zmprov mcf zimbraAttachmentsScanEnabled TRUE

在 Linux 防火墙中允许 Zimbra 管理面板的服务端口。

[root@zimbra-01 ~]# firewall-cmd --permanent --add-port=7071/tcp
success
[root@zimbra-01 ~]# firewall-cmd --reload
success

在客户端浏览器中打开 URL https://zimbra-01.onitroad.com:7071/。

注意：由于自签名 SSL 证书，浏览器会显示警告，我们必须忽略它才能继续，或者我们可以让网络中的 CA（证书颁发机构）对 SSL 证书进行数字签名。

使用管理员用户凭据登录。

我们现在位于 Zimbra 管理面板的仪表板，此处提供了许多选项。
我们可以自行探索。
我们现在在这里添加一个电子邮件帐户。

单击添加帐户。

添加有关电子邮件用户帐户的信息，然后单击完成。

再次在 Zimbra 管理控制台的仪表板上，单击注销。

在 Linux 防火墙中允许 Zimbra Web 邮件服务端口。

[root@zimbra-01 ~]# firewall-cmd --permanent --add-service=https
success
[root@zimbra-01 ~]# firewall-cmd --reload
success

使用客户端浏览器打开 URL https://zimbra-01.onitroad.com。

使用新创建的电子邮件用户登录。

我们已经以 jackli 用户登录。

同样，我们可以为我们的用户配置基于桌面的电子邮件客户端，如 Outlook、Thunderbird 等。
但是，在此之前，我们需要在 CentOS 7 服务器的防火墙中允许相关服务。

[root@zimbra-01 ~]# firewall-cmd --permanent --add-service={pop3,pop3s,imap,imaps,smtp,smtps}
success
[root@zimbra-01 ~]# firewall-cmd --reload
success

同样，要配置 XMPP 聊天客户端，我们必须在 Linux 防火墙中允许 XMPP 服务端口。

[root@zimbra-01 ~]# firewall-cmd --add-service=xmpp-client
success
[root@zimbra-01 ~]# firewall-cmd --reload
success

我们已成功安装 Zimbra Collaboration Suite 以在 CentOS 7 上配置邮件和聊天服务器。
