Installation and configuration process of iRedMail free mail server in CentOS 6 environment

I see that many VPS users are not using it to build websites, but are using it to create mail servers to send emails, so Snail also came to learn the application of this type of function. To learn and use building a mail server, you must first use the free and open source iRedMail software. iRedMail can quickly deploy mail server solutions in Red Hat, CentOS, SDebian, Ubuntu and other environment systems. In this article, Snail shares the process of successfully building it on Centos 6 32-bit system.

First, update the system installation package

yum update

Before preparing to install, you must update the system installation package, because if this problem is not dealt with, the installation error "Installation failed, please check the terminal output" will appear later.

Second, modify the current VPS host name HOSTNAME

Generally for the VPS we use, use \\"hostname -f\\" to check that the general host name is not the root domain name we need to set.

A – Edit the /etc/sysconfig/network file and set hostname to the email domain name mail.laozuo.org we need to create

B – Edit the /etc/hosts file and add the 127.0.0.1 mail.laozuo.org mail localhost.localdomain localhost script at the top. Note that it is changed to our own host name.

After restarting the VPS, use \\"hostname -f\\" to check and you will see that the current hostname has changed to what we need.

Third, resolve domain names

We need to set up A record and MX record resolution in domain name DNS resolution. Here Snail uses DNSPOD to make the domain name post office. The settings here are as follows:

This is the resolution of our domain name, the A record and the MX record, which are used exclusively by the post office.

Fourth, download and install iRedMail

cd /root/

wgethttp://www.iredmail.com/iRedMail-0.8.7.tar.bz2tar xjf iRedMail-0.8.7.tar.bz2cd iRedMail-0.8.7bash iRedMail.sh

Enter the download and installation steps above, and it will be installed automatically. You need to pay attention to whether the downloaded installation package contains random strings. If it is manually modified by SFTP, then decompress and install.

The installation process went smoothly and there were no errors. We just had to wait and then look at the setup part in the next step.

Fifth, iRedMail installation process and settings

A – Installation start welcome screen

Press Enter or click YES to confirm and start the installation settings. And when you see the /var/vmail installation path, press Enter by default.

B – Select database

Here I choose the MYSQL database as the data storage.

C – Set MYSQL database password

D – Set domain name

The domain name and host name set here cannot be the same.

E – Set Webmail and iRedAdmin administrator password

F- Select the integrated components that iRedMail needs to use

Then we just enter y directly and let it install.

Sixth, wait for iRedMail to be installed successfully

You need to insert a paragraph to set up the firewall and database configuration

After setting n and y, press Enter to continue the installation. If you see an interface like this, the installation is complete.

We can see that the installation is complete and the login portal is complete. By default, https login is required. We must either set up an SSL certificate to log in, or set $config[\\'force_https\\'] = true in the /var/www/roundcubemail/config/config.inc.php file; change the parameter to It will take effect after restarting after false.

In this way, iRedMail has been installed. I will add a specific application example later.
