This is based off the guide found at PHPIPAM

Here is a full guide on how to install phpIPAM on CentOS 7. This should work on all RHEL based distributions. For this guide I used completely fresh install of CentOS 7, we will do step by step guide for all applications needed for phpIPAM to run.
I used the following assumptions:
No software is installed on server (Apache, MySQL, php)
Database and apache server will run on same machine
phpipam will run in server root directory (will be accessible via http://ip_address/), no vhosts
Prettified links will be used
Only bare minimum configuration will be done

For phpIPAM to work we need to install and configure following applications:
Apache webserver
php with support for required modules for phpipam
MySQL database

1.) Preparing environment and installing required apps
1.1) Setting locale
To start let’s set correct locales to be used on server, they are required also for translations. Add following to file /etc/environment for en_US coding, add your encoding if you will use different:
[root@localhost ~]# more /etc/environment

1.2) Installing Apache, MySQL, PHP (LAMP) stack packages
Install all required packages for phpipam:
sudo yum install -y httpd mariadb-server php php-cli php-gd php-common php-ldap php-pdo php-pear php-snmp php-xml php-mysql php-mbstring php-mcrypt git

1.3) Configuring and running Apache webserver
Main apache configuration is in file /etc/httpd/conf/httpd.conf. Open it and change directory settings for /var/www/html to allow mod_rewrite URL rewrites:
<Directory “/var/www/html”>
Options FollowSymLinks
AllowOverride all
Order allow,deny
Allow from all
We also need to set server name, for now we will use localhost, change it to your FQDN:
ServerName locahost:80
Save file and exit.
Set correct timezone to php.ini to avoid php warnings:
[root@localhost html]# grep timezone /etc/php.ini
; Defines the default timezone used by the date functions
date.timezone = America/New_York
Now start apache webserver, and also make sure it starts at boot:
sudo systemctl start httpd
sudo systemctl enable httpd
Firewall rule is also needed to pass http/https traffic to webserver from external interfaces if needed with following command:
sudo firewall-cmd –permanent –add-port=80/tcp
sudo firewall-cmd –permanent –add-port=443/tcp
sudo firewall-cmd –reload
And make sure upload folders are accessible for xls/csv imports:
sudo chown apache:apache -R /var/www/html/
sudo chcon -t httpd_sys_content_t /var/www/html/ –R

1.4) Configuring and running MySQL (MariaDB) database server
MariaDB has replaced MySQL server in CentOS 7, so we will use it. First start MariaDB server and make it start at boot time:
sudo service mariadb start
sudo chkconfig mariadb on
Default options are ok, we just need to set root password, so issue folowing command and follow instructions to harden MariaDB server:
sudo mysql_secure_installation

2.) Downloading phpipam files and configure phpipam
We have configured database and webserver, it is time to install and configure phpipam.

2.1) Downloading phpipam installation files
For the purpose of this guide we will use git to fetch files directly from Github repository. This is preferred and easiest way to setup and maintain phpipam. For other options please read Download guide.

cd /var/www/html/

git clone .

Cloning into ‘.’…
remote: Counting objects: 10513, done.
remote: Compressing objects: 100% (2/2), done.
remote: Total 10513 (delta 0), reused 0 (delta 0), pack-reused 10511
Receiving objects: 100% (10513/10513), 7.84 MiB | 2.59 MiB/s, done.
Resolving deltas: 100% (7310/7310), done.

git checkout 1.2

phpipam code is now downloaded in /var/www/html, which is out document root. To use development version omit the “git checkout 1.2” command, this will use current MASTER version.
* If you wish to make separate subfolder for phpipam, e.g. to access phpipam on http://ip_address/phpipam/, than install files to /phpipam/ subfolder:

cd /var/www/html/

git clone phpipam

cd phpipam

git checkout 1.2

2.2) Configuring database connection
Next we need to configure connection to database. To do it we first need to copy over sample config file to config.php that phpipam uses:

cp config.dist.php config.php

Now open config.php file and set settings for database connection. Do not use root user/pass, whatever you put here will be used for further connections to database and users from config.php will be automatically created.
BASE directive should be left at / because we will serve phpipam from default directory http://ip_address/. If you changed this adjust BASE directive accordingly.

3.) phpipam installation
We are now ready to install phpipam. Open browser and go to http://ip_address/ to start with automatic database installation. For MySQL connection enter root username and password you created in point 1.4, this will only be used to create required databases, tables and grants. After installation is completed phpipam will used username/password entered in config.php file to access database, root password is not stored anywhere.
Here are screenshots of install process:
4.) Enable Pretty Links and API
Go to Administration and PHPSettings set Pretty Links to YES

Under Feature Settings check API is set to ON
5.) Create API Key

Click on Administrative and then API and select Create API Key
Set it up as above and make a note of the App id as you will need this for in ManageIQ / CloudForms
4.) phpipam upgrade
Upgrade process is simple if you are using git, please read this guide for full upgrade guide. In our case all we need to do is pull code updates from github and open browser to start upgrade:
[root@localhost ~]# cd /var/www/html
[root@localhost html]# git pull

5.) Enabling network scanning
To enable network scanning we have two options: disable SELinux or create policy for it. Creating SELinux policy is recommended, please read this topic. For now we will disable SELinux by entering setenforce 0 command:
[root@localhost html]# getenforce
[root@localhost html]# setenforce 0
[root@localhost html]# getenforce
[root@localhost html]#
This will enable icmp check from web, discovery etc. To scan networks simultaneously and periodically check address statuses please read this guide.

6.) Backup database via cron
It is recommended that you make daily backups of your database files via cron. For daily backups use following cronjob:

Backup IP address table, remove backups older than 10 days

@daily /usr/bin/mysqldump -u ipv6 -pipv6admin phpipam > /var/www/html/db/bkp/phpipam_bkp_$(date +”\%y\%m\%d”).db
@daily /usr/bin/find /var/www/html/db/bkp/ -ctime +10 -exec rm {} \;
