Step 1: Check System Requirements:

Before proceeding with the fix, ensure that your CentOS 6.2 x86_64 system meets the minimum system requirements for Zimbra. Make sure you have sufficient resources, such as CPU, memory, and disk space, to run Zimbra smoothly. Additionally, verify that you have a stable internet connection for downloading the necessary packages.

Step 2: Install Required Packages:

To resolve the “Initializing ldap…failed” issue, you may need to install additional packages. Open a terminal or connect to your server via SSH and execute the following commands:

sudo yum install perl -y
sudo yum install nc -y

These commands will install the required Perl and nc (netcat) packages, which are necessary for Zimbra to function properly.

Step 3: Disable SELinux:

SELinux (Security-Enhanced Linux) is a security mechanism that can interfere with the proper functioning of Zimbra. To avoid any conflicts, it is recommended to disable SELinux temporarily during the installation process. Open the SELinux configuration file using a text editor:

sudo vi /etc/selinux/config

Locate the line that says SELINUX=enforcing and change it to SELINUX=disabled. Save the file and exit the text editor.

Step 4: Reboot the System:

To apply the changes made to SELinux, reboot your CentOS system by executing the following command:

sudo reboot

After the reboot, SELinux will be disabled, allowing Zimbra to initialize the LDAP service without any interference.

Step 5: Retry Zimbra Installation:

Once your system has restarted, attempt to install Zimbra again using the installation command appropriate for your Zimbra version. For example:

sudo ./install.sh

Follow the on-screen prompts to complete the installation process. With SELinux disabled and the required packages installed, Zimbra should be able to initialize the LDAP service successfully.

Conclusion:

In this guide, we have addressed the “Initializing ldap…failed” error during Zimbra installation on CentOS 6.2 x86_64. By ensuring system requirements are met, installing the required packages, disabling SELinux, and retrying the installation, you should be able to resolve the issue and successfully install Zimbra on your system.

    Hi!
    I followed your instruction and finish the installation. But when i enter my address of my server in Firefox, it always show the connecting message but cannot show the webmail for me to login.
    I checked my server with netstat command and i saw a connection from my client (Firefox) to server.
    My server is CentOS 6.5 with Zimbra 7.1.3
    Thank you!
