Before we proceed with Zimbra Collaboration Suite installation process, first login to your server console with root privileges and install the following packages:
# yum -y install unzip net-tools sysstat openssh-clients perl-core libaio nmap-ncat libstdc++.so.6 perl perl-core ntpl nmap sudo libidn gmp libaio libstdc++ unzip sqlite dnsmasq
Next, issue getenforce command to check if Selinux in enabled on your machine. In case the policy is set to Enforced disable it by issuing the below commands:
# getenforce # setenforce 0 # getenforce
To completely disable Selinux on CentOS, open /etc/selinux/config file with a text editor and set the line SELINUX to disabled.
Assure that wget system utility is also installed on your system by issuing the following command:
# yum install wget
In order for Zimbra to function correctly you must set the local machine hostname and FQDN to point to your server IP Address by running the below commands from root account:
# hostnamectl set-hostname mail # echo "192.168.0.14 mail.centos7.lan mail " >> /etc/hosts # cat /etc/hosts
Replace the system hostname and FQDN values accordingly in order to match your own domain settings. Test the hostname and FQDN values by issuing the ping command against both records.
# ping -c1 mail.centos7.lan # ping -c1 mail
Disable Firewall for now.
#systemctl disable firewalld
Patch the system with latest updates
#yum update -y
Disable postfix
#systemctl disable postfix
Create /etc/dnsmasq.d/zimbra.conf with:
server=192.168.0.14 domain=centos7.lan mx-host=centos7.lan,mail.centos7.lan,5 listen-address=127.0.0.1 address=/mail.centos7.lan/127.0.0.1
where, multiple ‘server=’ lines can be there for upstream DNS.
Start and enable dnsmasq using:
systemctl start dnsmasq systemctl enable dnsmasq
[root@localhost locale]# hostname mail.lqs.co.in
