This tutorial describes how to install Zimbra Collaboration Suite Open Source Edition on a CentOS\/RHEL 7 VPS server.<\/p>\n\n\n\n

Step 1: Create both A and MX records for Zimbra Mail Server. Create both A and MX records on the VPS to point to your Zimbra mail server<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 2: Install System Packages for Zimbra<\/p>\n\n\n\n

Login as a root account to install the following packages below:<\/p>\n\n\n\n

# yum -y install unzip net-tools sysstat openssh-clients perl-core libaio nmap-ncat libstdc++.so.6<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Next, disable SELinux in CentOS. Edit \/etc\/selinux\/config file and run a command setenforce 0 to disable SELinux in CentOS<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Install wget package:<\/p>\n\n\n\n

# yum install wget<\/p>\n\n\n\n

Set hostname on Zimbra host. # hostnamectl set-hostname mail<\/p>\n\n\n\n

Disable unwanted services. Postfix mail service has already been installed and run on CentOS. We need to disable and remove the postfix service before installing Zimbra.<\/p>\n\n\n\n

# systemctl stop postfix<\/p>\n\n\n\n

# systemctl disable postfix<\/p>\n\n\n\n

# yum remove postfix<\/p>\n\n\n\n

Step 3: Install Zimbra Collaboration Suite Open Source Edition # wget https:\/\/files.zimbra.com\/downloads\/8.8.15_GA\/zcs-8.8.15_GA_3869.RHEL7_64.20190918004220.tgz<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

After the download completes, use unzip<\/strong> command to extract the archive<\/p>\n\n\n\n

# tar xfz zcs-8.8.15_GA_3953.RHEL8_64.20200629025823.tgz<\/p>\n\n\n\n

# cd zcs-8.8.15_GA_3953.RHEL8_64.20200629025823\/ # ls<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Run the command install.sh to install Zimbra. After a series of system checks, click y in continue installation <\/p>\n\n\n\n

# .\/install.sh<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Next, the installation process will prompt a couple of questions that we need to choose to configure Zimbra properly.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Finally, it will start the Zimbra installation process. The system will be modified.  Continue? [N] y<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Allow Zimbra services on Linux Firewall.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 4: Zimba Initial Configuration. After the installation finishes, access the Zimbra administration page via a link https:\/\/mail.cisa2380.tk:7071<\/a> or https:\/\/172.105.5.143:7071<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Step 5: Create 500 Zimbra test users:<\/p>\n\n\n\n

#su \u2013 zimbra<\/p>\n\n\n\n

$cd \/opt\/mail\/backup<\/p>\n\n\n\n

$touch usercreation.sh<\/p>\n\n\n\n

$nano usercreation.sh<\/p>\n\n\n\n

[zimbra@mail backup]$ more usercreation.sh<\/p>\n\n\n\n

#!\/bin\/bash<\/p>\n\n\n\n

# Generate user list<\/p>\n\n\n\n

#cd \/var\/tmp<\/p>\n\n\n\n

x=1<\/p>\n\n\n\n

while [ $x -lt 501 ] do<\/p>\n\n\n\n

echo “ca demo$x@cisa2380.tk ‘@zimbra@password’ cn ‘Demo User${x}’ givenName ‘Demo’ zimbraPrefFromDisplay ‘Demo User${x}'” >> userlist.zmp<\/p>\n\n\n\n

x=`expr $x + 1` done<\/p>\n\n\n\n

# run the script .\/usercreation.sh<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Next, use the command below to create 500 Zimbra users from the userlist.zmp file $zmprov -f userlist.zmp<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

List down all Zimbra accounts with zmprov command $zmprov -l gaa<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Checking on Zimbra Administration.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 6: Evaluate Zimbra performance by simulating concurrent Zimbra user’s login.<\/p>\n\n\n\n

—-<\/p>\n\n\n\n

[root@li1978-114 tmp]# cat usersimulate.sh<\/p>\n\n\n\n

#!\/bin\/bash<\/p>\n\n\n\n

# Simulate user login<\/p>\n\n\n\n

# x start from 1 and end with 500<\/p>\n\n\n\n

#x=1<\/p>\n\n\n\n

for x in {1..500}<\/p>\n\n\n\n

do<\/p>\n\n\n\n

    curl -v -k ‘https:\/\/mail.cisa2380.tk\/’ -H ‘Cookie: ZM_TEST=true’ –data ‘loginOp=login&username=demo$x@cisa2380.tk&password=@zimbrapassword’<\/p>\n\n\n\n

    sleep 1s done<\/p>\n\n\n\n
