先决条件：
1、系统环境配置：
操作系统：CentOS 6.5 x86_64（Zimbra不支持32位操作系统） 内网IP：192.168.0.240 Zimbra版本：Zimbra 8.6.0开源免费版 点击下载 邮箱域名：corp.net 主机名：mail.corp.net
软件依赖安装：yum -y install libidn11 curl fetchmail libpcre3 libgmp3c2 libxml2 libstdc++6 openssl perl sysstat libtool-ltdl compat-libstdc* nc file unzip libaio
2、DNS设置：
安装Zimbar需要先对域名设置MX记录，指向Zimbra服务器。如内部有DNS服务器器，可以先在DNS服务器上添加域名的记录，把Zimbra服务器的DNS指向DNS服务器IP；等安装完成后，再把DNS修改回原来的设置，最后做端口映射等。
在Zimbra服务器上用nslookup命令检测DNS的正确性：
# nslookup -q=mx corp.net Server:192.168.0.180 Address:192.168.0.180#53 Non-authoritative answer: corp.net mail exchanger = 5 mail.corp.net. # nslookup -q=a mail.corp.net Server:192.168.0.180 Address:192.168.0.180#53 Non-authoritative answer: Name:mail.corp.net Address: 192.168.0.240
安装准备：
1、关闭selinux
# vi /etc/selinux/config SELINUX=disabled
2、关闭iptables防火墙端口
# service iptables stop # chkconfig iptables off
3、关闭postfix服务，避免25端口被占用
# service postfix stop # chkconfig postfix off
4、配置主机名
# vi /etc/sysconfig/network HOSTNAME=mail.corp.net
5、配置hosts
# vi /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 #::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.0.240 mail.corp.net mail
6、空间要求
Zimbra会安装到/opt目录，请确保/opt目录有至少5G的可用容量
7、重启服务器，确保所有配置生效
# reboot
安装：
1、把下载的Zimbra安装包上传到/opt
2、解压
# cd /opt # tar -zxvf zcs-8.6.0_GA_1153.RHEL6_64.20141215151155.tgz # cd zcs-8.6.0_GA_1153.RHEL6_64.20141215151155
3、运行安装脚本开始安装（安装过程中请按照下面红色字符进行操作）
[root@mail zcs-8.6.0_GA_1153.RHEL6_64.20141215151155]# ./install.sh

You have the option of notifying Zimbra of your installation.
This helps us to track the uptake of the Zimbra Collaboration Server.
The only information that will be transmitted is:
The VERSION of zcs installed (8.6.0_GA_1153_RHEL6_64)
The ADMIN EMAIL ADDRESS created (admin@corp.net)
Notify Zimbra of your installation? [Yes] No

至此，Zimbra8.6.0安装完成。
管理：
WebMail登录地址：https://mail.corp.net 或 https://192.168.0.240

uninstall卸载
登陆root用户
1) 执行以下面的命令，su切换 到zimbra用户，停止zmcontrol服务，然后再退出zimbra帐户
su – zimbra
zmcontrol stop
exit
(you should be root after you run exit)
2a) 执行下面的命令，查看系统中是否还有zimbra进程
ps -ef | grep -i zimbra
如果看到还有zimbra进程，就用下面的命令，kill掉进程
2b) 用kill -9强制杀死进程:
kill -9 <zimbra的进程号>
3a) 执行以下命令:
df
如果你能看到 “amavisd”
3b) 那就执行以下命令:
umount /opt/zimbra/amavisd<-new-blah>/tmp
4) 进入你安装时解压出来的源文件目录（即安装文件目录）
cd /<tmp_tar_install_dir>/zcs/
tmp_tar_install_dir：你的文件路径，如我所下载来的安装包，都是放在/usr/local/src下面的，然后把安装包改名成zcs，这个你应该明白吧？不明白？可联系我
cd /usr/local/src/zcs/
[root@linuxyw zcs]# ls
README.txt data install.sh readme_binary_en_US.txt util
bin docs packages readme_source_en_US.txt
[root@linuxyw zcs]# pwd
/usr/local/src/zcs
5)执行以下命令：
./install.sh -u
6)执行以下的命令完成卸载
rm -rf /opt/zimbra
rm -rf /var/log/*zimbra*
rm -rf /tmp/*zimbra*
rm -rf /tmp/hsperfdata*
rm -rf /tmp/install.*
rm -rf /tmp/*swatch*
rm -rf /tmp/log*
进以下面的目录中，查看下，确保所有用户拥用者zimbra的文件全部删除
/var/log/
/tmp/
7)执行以下命令，删除zimbra用户和组:
userdel zimbra
userdel postfix
groupdel zimbra
groupdel postfix
8）在 /etc/fstab中删除这行内容（如果没有这行就跳过吧）：
/dev/shm /opt/zimbra/amavisd-new-2.4.1/tmp tmpfs defaults,users,size=150m,mode=777 0 0
9) 在/etc/syslog.conf中删除以下几行，一般在文件最后的位置（如果你是用centos6.x系统，文件名应该/etc/rsyslog.conf
local0.* -/var/log/zimbra.log
auth.* -/var/log/zimbra.log
mail.* -/var/log/zimbra.log
10) 执行以下命令，删除日志配置文件(CentOS, RHEL)
rm -f /etc/logrotate.d/zimbra
11) 在 /etc/prelink.conf文件中删除以下内容 (CentOS, RHEL)
# added for Zimbra
-l /opt/zimbra/lib
-l /opt/zimbra/sleepycat/lib
-l /opt/zimbra/openldap/lib
-l /opt/zimbra/cyrus-sasl/lib
-l /opt/zimbra/mysql/lib
12) 在/etc/rc* 中删除zimbra自启动(CentOS, RHEL)
chkconfig –del zimbra
到此就完成Zimbra卸载了
