Posted by Usually, i am always using SUSE Linux Enterprise Server as operating system for Zimbra Mail Server. But, starting from Zimbra 9.x.x, SLES has been deprecated (end of life) and may be will not supported by Zimbra. Therefore, i attempt to using CentOS as operating system for Zimbra. For easy understanding, this is my information system
Domain : imanudin.net Hostname : mail IP Address : 192.168.80.91 Gateway : 192.168.80.11
# Configure Network
First, we must configure network on CentOS. Assuming name of your network interface is eth0
vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0 ONBOOT=yes NM_CONTROLLED=no BOOTPROTO=none IPADDR=192.168.80.91 NETMASK=255.255.255.0 DNS1=192.168.80.91 GATEWAY=192.168.80.11 DNS2=192.168.80.11 DNS3=8.8.8.8 USERCTL=no
Restart network service and setup for automatic boot
service network restart chkconfig network on
# Configure Disable Selinux & Firewall
Open file /etc/sysconfig/selinux and change SELINUX=enforcing become SELINUX=disabled. Also disable some service such as iptables and ip6tables.
setenforce 0 service iptables stop service ip6tables stop chkconfig iptables off chkconfig ip6tables off
# Configure /etc/hosts, /etc/resolv.conf and hostname
Open file /etc/hosts and configure as follows
127.0.0.1 localhost 192.168.80.91 mail.imanudin.net mail
Open file /etc/resolv.conf and configure as follows
search imanudin.net nameserver 192.168.80.91 nameserver 192.168.80.11 nameserver 8.8.8.8
Do the following command as root and open file /etc/sysconfig/network to change hostname to the name mail.imanudin.net
hostname mail.imanudin.net vi /etc/sysconfig/network
Change HOSTNAME so that like below :
NETWORKING=yes HOSTNAME=mail.imanudin.net
# Disable service sendmail or postfix
Do the following command as root
service sendmail stop service postfix stop chkconfig sendmail off chkconfig postfix off
# Update repo and install packages dependencies needed by Zimbra
yum update yum -y install perl perl-core wget screen w3m elinks openssh-clients openssh-server bind bind-utils unzip nmap sed nc sysstat libaio rsync telnet aspell
# Configure local DNS Server
Zimbra needed lookup to MX records on domain that used. For that purpose, we can configure dns server on the same machine with Zimbra mail server
Open file /etc/named.conf and add any on listen-on port 53 and allow-query as follows
listen-on port 53 { 127.0.0.1; any; };
allow-query { localhost; any; };
Create a zone at the bottom of file named.conf as follows
zone "imanudin.net" IN {
type master;
file "db.imanudin.net";
allow-update { none; };
};
Create database for a new zone who has been created in folder /var/named/
touch /var/named/db.imanudin.net chgrp named /var/named/db.imanudin.net vi /var/named/db.imanudin.net
fill as follows
$TTL 1D
@ IN SOA ns1.imanudin.net. root.imanudin.net. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
@ IN NS ns1.imanudin.net.
@ IN MX 0 mail.imanudin.net.
ns1 IN A 192.168.80.91
mail IN A 192.168.80.91
# Restart Service & Check results configuration of DNS Server
service named restart chkconfig named on nslookup mail.imanudin.net dig imanudin.net mx
If results from above command like follows, your dns configuration has been success
[root@mail opt]# nslookup mail.imanudin.net Server: 192.168.80.91 Address: 192.168.80.91#53 Name: mail.imanudin.net Address: 192.168.80.91
Preparation for install Zimbra has been finished. Now we can install zimbra and will explained on part 2 😀
Good luck and hopefully useful 😀

saya punya masalah commnad di sendmail stop
kenapa tidak bisa ya
[root@localhost ~]# service sendmail stop
sendmail: unrecognized service
[root@localhost ~]# service postfix stop
[root@localhost ~]#
Hi mas,
Untuk service sendmail masalah karena service tersebut tidak ada. Itu bisa diignore, karena hanya memastikan saja bahwa semua service yang berpotensi bentrok dengan Zimbra distop dan didisable

Hi
Thanks for your nice tutorial. I have a server on centos 7 with vestacp. how can I install zimbra mail on a same server. Kindly let me know its configuration. I will remain thankful.
My email id: sarfaraz.leghari@hotmail.com
Regards
Hi Sarfaraz Ali,
I think Zimbra will conflict with Vestacp (port 80, 25 and another port that used by Zimbra). I recommend you to install on another server
Hi iman,
I’am using open source zimbra mail, its sowing the following error in log while sending mails to other domain
Status=differed (Delivery temporarily suspended: lost connection with alt3.aspmx.l.google[74.125.30.27] while receiving the initial server greeting)
Hi Rahul,
Its seems your internet connection too slow. Try to increase
Dear Iman,
We have internet connection on the server even tested on the browser all the pages getting opened. But we are getting the same error. please help us on this.
Dear Sir,
We are using Zimbra network edition oracle Linux 6, now we need to change existing server to new one.
We purchased DL380 server and installed same version, host name and ip address. So we need to put old server backup to new server so please give me an idea how to put old server backup to new server
Hi Noushad,
You can rsync /opt/zimbra from old server into new one. After that, you can test starting Zimbra on the new one server. I’m often do that on my clients 🙂
Hi Iman,
As moved our mail server to production. But getting the below error,
‘Oct 18 23:40:00 mail zimbramon[5684]: 5684:crit: Disk warning: mail.mydomain.com: / on device /dev/mapper/vg_mailserver-lv_root at 100%

Hi Manikandan,
I see your LVM configuration is not good. As Zimbra folder placed on /opt, the bigger size of your partition is should be / or /opt. Not /home.
If you want to change, you can copy all /opt/zimbra into /home folder and then change mounting lv_home into /opt
Hi Iman,
Simply can i cut and paste the opt folder into lv_home will work or need to do some config. Also please provide the instruction to change mounting lv_home into /opt. Thank you for your quick response.
Hi Manikandan,
You do not need some configuration again. For change lv_home, you can open /etc/fstab and change from /home into /opt
Is it a good idea to install Zimbra on the same machine I intend to use as a file and web server? Someone told me that Zimbra doesn’t like to share. What can I do and what can’t I do with the machine Zimbra is using?
Hi Brian,
I am recommend you to do not install web server on the same machine with Zimbra. But, you can to use Zimbra as file server also (but not recommended). This is because Zimbra have ports 80 and 443 which are will conflict with web server
Dear Sir,
Please provide me offline restore steps,i configure test server and copied latest backup from our production server.(opt/zimbra/backup)
Now i need to restore this backup to test server
Hi Noushad,
You can try the guidance from this link : https://wiki.zimbra.com/wiki/Backing_up_and_restoring_Zimbra_(Open_Source_Version)
Dear sir,
How can i change the path the volume of all message of user.
Usual path is. /opt/Index for index and for data . /opt/data
Thank you sir Godbless
Hi,
Yes, you can add another index and data from Zimbra admin and make it as current. Please see from the following link : https://www.zimbra.com/docs/os/6.0.10/administration_guide/Managing_ZCS.08.4.html#1069946
Now i know sir. thank you so much sir
Hi Iman,
Hope you are doing good!!
We are having the physical server in our environment IP:192.168.2.201. I got the task from my TL that physical server(192.168.2.201) need to be moved to the virtual server (192.168.2.44). we need all the user mails and groups to the virtual server as in the 192.168.2.201. Please suggest the idea.
Hi Manikandan,
If you are using VMware, you can use VMware converter. If not, you can rsync all /opt/zimbra folder in the physical server into virtual server
