如何在Zimbra CentOS 7上安装Zextras Suite
最近，我负责将域，用户帐户和所有邮箱从在Ubuntu 16.04上运行的Zimbra 8.6迁移到在CentOS 7上运行的Zimbra 8.x的方法。
有两种潜在的实现方法：在CentOS 7上安装Zimbra 8.8并编写bash脚本以促进域，用户帐户，通讯组列表，联系人，日历，便笺，转发规则和所有其他用户首选项的迁移。
这将是一项艰巨的任务，过程将很慢且容易出错。
使用Zextras Suite在服务器之间迁移数据。
它支持从单服务器到多服务器设置的迁移。
系统要求：
就绪的Zimbra设置，可以是单服务器安装，也可以是多群集安装。
对于Zimbra的多服务器安装，请查看我们以前的指南–> https://theitroad.com/zimbra-multi-server-installation-on-centos-7/Downloaded Zextras Suite，它将安装在所有运行邮箱的服务器上守护程序。
请记住一一安装。
特别是如果LDAP服务器在邮箱服务器上运行。
ZeXtrasSuite使用端口8735和8736进行存储间通信，请确保服务器可以在此端口上相互访问，并且该端口对外部通信是封闭的。
我们可能需要禁用SELinux或者将其置于许可模式。
请注意，必须在所有商店服务器(运行了邮箱服务的服务器)上安装zeXtras Suite。
在Zimbra CentOS 7上安装Zextras Suite
下载最新版本的Zextras Suite：
wget http://download.zextras.com/zextras_suite-latest.tgz
该软件包包含以下组件：ZeXtras Suite Core，缩写为ZeXtras Core或者Core，是一个jar包，扩展了ZimbraZeXtras Suite Administrative Zimlet(缩写为ZeXtras Suite Zimlet)或者Zimlet(访问和管理Core.Zimlet的管理Zimlet)的功能。
Zimbra的开源抽象层。
安装脚本遵循上述结构，可为我们提供三个安装目标：核心，zimlet和全部。
后者等效于安装核心以及紧随其后的zimlet。
在防火墙上打开8735和8736 TCP端口：
sudo firewall-cmd --permanent --add-port 8735/tcp sudo firewall-cmd --permanent --add-port 8736/tcp sudo firewall-cmd --reload
解压缩Zextras Suite软件包
现在打开包装，以便开始安装。
tar xvf zextras_suite-latest.tgz
转到Zextras Suite目录：
cd zextras_suite
通过运行带有all选项的./install.sh bash脚本开始安装。
sudo ./install.sh all
要获取帮助，请运行：
# ./install.sh -h ./install.sh -h | ./install.sh [ -u ] [ -d ] all|zimlet|core -h This very message -d Activates debug mode for the install script -u Uninstall the target The targets available for (un)installation are: core -- Core zimlet -- Zimlet all -- Core followed by Zimlet * In order to use both * core and zimlet need to be installed.
我们应该获得如下输出：

清除服务器缓存：
sudo su - zimbra -c 'zmprov fc -a zimlet'
初始化Zextras备份
安装完成后，让我们初始化Zextras Backup。
为了正常工作，ZeXtras Backup在文件系统上需要一个专用目录来保存其所有配置和所有备份数据。
该目录的默认路径是/opt/zimbra/backup/zextras /。
初始化过程会自动创建文件夹结构和所需的配置文件。
我们需要执行初始化过程：在安装ZeXtras Suite之后，立即在ZeXtras Administration Zimlet的ZxBackup选项卡中更改"备份目标路径"。
在NFS上配置ZxBackup(可选)
如果我们有兴趣为ZxBackup配置NFS，请执行以下步骤。
如果要使用默认的备份路径/opt/zimbra/backup/zextras /步骤1：为ZeXtras Backup备份数据添加磁盘并在其上创建文件系统，请跳过此部分。
sudo parted /dev/xvdc mklabel gpt sudo parted /dev/xvdc mkpart primary 0% 100% sudo mkfs.xfs /dev/xvdc1
第2步：挂载文件系统我将/dev/xvdc1挂载到/mnt目录，并为ZeXtras备份创建一个单独的目录。
sudo mount /dev/xvdc1 /mnt sudo mkdir /mnt/zextras sudo chown -R zimbra:zimbra /mnt/zextras
步骤3：安装和配置NFS服务器
sudo yum -y install nfs-utils
获取Zimbra用户的UID/GID
# id zimbra uid=996(zimbra) gid=993(zimbra) groups=993(zimbra),5(tty)
配置导出文件
$sudo vim /etc/exports /mnt/zextras 192.168.1.0/24(rw,anonuid=996,anongid=993,no_root_squash)
将192.168.1.0/24替换为我们需要可从中访问NFS服务的子网。
步骤4：启动并启用NFS服务
sudo systemctl start rpcbind nfs-server sudo systemctl enable rpcbind nfs-server
步骤5：在防火墙上打开nfs端口
sudo firewall-cmd --add-service=nfs --permanent sudo firewall-cmd --reload sudo exportfs -rvv
步骤6：在所有邮箱服务器(源和目标)上安装NFS路径一切都应准备就绪，继续配置nfs客户端。
sudo yum -y install nfs-utils sudo systemctl start rpcbind && sudo systemctl enable rpcbind
配置fstab以进行持久挂载：
192.168.1.10:/mnt/zextras /mnt/zextras nfs defaults 0 0
创建/mnt/zextras目录，并将所有权更改为zimbra用户和组：
sudo mkdir -p /mnt/zextras sudo chown -R zimbra:zimbra /mnt/zextras sudo mount -a sudo df -hT | grep /mnt/ze
初始化指南
要初始化ZeXtras备份模块，只需执行以下步骤即可运行SmartScan：访问Zimbra Admin界面。
在管理控制台的左窗格中，选择ZeXtras以显示ZeXtras面板。
单击Backup选项卡(需要ZeXtras Suite Trial或者有效许可证)。
在"基本备份配置"下，单击"立即初始化"。
如果配置了NFS部件，请记住将路径从/opt/zimbra/backup/zextras /更改为/mnt/zextras。
使用以下命令查看初始化进度：
sudo su - zimbra -c "zxsuite backup monitor"
一旦完成SmartScan，ZxBackup将被完全初始化并正常工作！该操作被推入队列，操作完成后将立即通知我们。
为了监视此操作的进度，请以zimbra用户身份在shell中运行以下命令：
sudo su - zimbra $zxsuite backup monitor 29b58b66-4a41-4816-b5c8-6a4e035cf50f
ZeXtras Suite卸载
拆卸过程与安装过程大致相似。
需要在所有目标之前放置-u开关。
该脚本将验证任何ZeXtras Suite组件的存在并提示将其删除。
./install.sh -u all
这将同时卸载ZeXtras Core和ZeXtras Administration Zimlet要仅卸载ZeXtras Core，请运行：
./install.sh -u core
通过运行以下命令删除ZeXtras Administration Zimlet：
./install.sh -u zimlet
安装后和卸载后
在安装或者卸载ZeXtras Suite之后，强烈建议我们清除浏览器和服务器的缓存。
要清除服务器的Zimlet缓存，请以zimbra用户身份运行以下命令：
$zmprov fc zimlet
