Step‑by‑Step Installation and Configuration of phpIPAM on CentOS

1. Introduction

For operations staff, managing IP addresses and subnets manually in spreadsheets quickly becomes unmanageable as networks grow; an automated IP address management (IPAM) system provides real‑time monitoring and reporting.

2. About phpIPAM

phpIPAM is an open‑source web IP address management application written in PHP with a MySQL/MariaDB backend, using jQuery, AJAX and HTML5/CSS3 features.

3. System Preparation

Disable SELinux and reboot

sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config && reboot

Stop the firewall systemctl stop firewalld Install required packages

yum install epel-release -y
yum install wget vim net-tools httpd mariadb-server php php-cli php-gd php-common php-ldap php-pdo php-pear php-snmp php-xml php-mysql php-mbstring git -y

4. Apache Configuration

Modify /etc/httpd/conf/httpd.conf (example changes):

ServerName localhost:80

<Directory "/var/www/html">
  Options FollowSymLinks
  AllowOverride all
  Order allow,deny
  Allow from all
</Directory>

Test the configuration: httpd -t -f /etc/httpd/conf/httpd.conf Set PHP timezone in /etc/php.ini: date.timezone = Asia/Shanghai Enable and start Apache:

systemctl enable httpd
systemctl start httpd

5. MariaDB Initialization

Start and enable MariaDB:

systemctl start mariadb
systemctl enable mariadb

Secure the installation (run the interactive script):

mysql_secure_installation

6. Download and Prepare phpIPAM

Clone the repository and checkout version 1.4:

cd /var/www/html
git clone https://github.com/phpipam/phpipam.git .
git checkout 1.4

Set file ownership for Apache: chown apache:apache -R /var/www/html Copy the default configuration file and rename it:

cp /var/www/html/config.dist.php /var/www/html/config.dist.php.bak
mv /var/www/html/config.dist.php /var/www/html/config.php

Edit /var/www/html/config.php to set the base path: define('BASE', "/phpipam"); Restart Apache to apply changes:

systemctl restart httpd

7. Web Installation

Open http://<em>server‑IP</em>/phpipam in a browser, select a new installation, create the phpIPAM database, and follow the on‑screen wizard to configure the admin account and initial settings.

8. Post‑Installation Usage

After logging in, you can:

Switch the admin interface language to Chinese (requires logout and login again).

Create, edit, and delete subnets.

View subnet details and edit individual IP entries.
