How To Install Cacti Monitoring V1.2.3 on Ubuntu 18.04 LTS

Cacti is an open-source, web-based network monitoring and graphing tool designed as a front-end application for the open-source, industry-standard data logging tool RRDtool. It is used by IT businesses and stores all of the necessary information about bandwidth, hard disk usage, CPU usage, load average, RAM statistics etc in a MySQL database. Cacti creates graphs and populates them with data. It offers SNMP support, 3rd party templates and plugins and has built in user authentications and user permission features.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Cacti Monitoring on a Ubuntu 18.04 (Bionic Beaver) server.

Install Cacti Monitoring on Ubuntu 18.04 LTS

Step 1. First make sure that all your system packages are up-to-date Install Cacti Monitoring on Ubuntu 18

sudo apt-get update
sudo apt-get upgrade

Step 2. Install LAMP (Linux, Apache, MariaDB and PHP) server.

A Ubuntu 18.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here. Also install all required PHP modules:

apt-get install php7.1-cli php7.1-gd php7.1-opcache php7.1-mysql php7.1-json php7.1-mcrypt php7.1-xml php7.1-curl

Step 3. Configuring MariaDB for Cacti.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. you should read and below each steps carefully which will set root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB:

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

Next we will need to log in to the MariaDB console and create a database for the Cacti. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for Cacti installation:

Ccreate database cacti;
GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'cactipassword';
flush privileges;
exit

The newly created database user (cactiuser) should have access to the mysql.time_zone_name Table. To do that, import the mysql_test_data_timezone.sql to mysql database:

mysql -u root -p mysql < /usr/share/mysql/mysql_test_data_timezone.sql

Then, log in to Mariadb:

mysql -u root -p

Grant the permission to cactiuser:

GRANT SELECT ON mysql.time_zone_name TO cactiuser@localhost;
flush privileges;
exit

Step 4. Installing the Cacti packages.

Install SNMP and SNMP and RRDtools:

sudo apt-get install snmp snmpd snmp-mibs-downloader rrdtool

How To Install Multiple PHP V7.1.28 Version on Ubuntu 18.04 LTS

Install Multiple PHP Version on Ubuntu 18

PHP (recursive acronym for PHP: Hypertext Preprocessor) is an open source, popular general-purpose scripting language that is widely-used and best suited for developing websites and web-based applications. It is a server-side scripting language that can be embedded in HTML.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Multiple PHP Versionon a Ubuntu 18.04 (Bionic Beaver) server.

Install Multiple PHP Version on Ubuntu 18.04 LTS

Step 1. First make sure that all your system packages are up-to-date

sudo apt-get update
sudo apt-get upgrade
sudo apt install apache2 libapache2-mod-fcgid

Step 2. Installing PHP.

First add the PPA to your system:

sudo apt install python-software-properties
sudo add-apt-repository ppa:ondrej/php

For this tutorial, we are using the PHP 5.6 and PHP 7.2 to configure with Apache web server. To use the multiple PHP versions, we will use PHP FPM:

apt update
sudo apt install php5.6 php5.6-fpm
sudo apt install php7.2 php7.2-fpm

After installation, check status PHP services are running:

systemctl status php5.6-fpm
systemctl status php7.2-fpm

Step 3. Apache Web Server Configuration.

First, create two directories on your server:

mkdir /var/www/php56
mkdir /var/www/php72

Next, create a test file named info.php with he content below. Save the file, then browse to it to see if PHP is working:

echo "<?php phpinfo(); ?>" > /var/www/php56/index.php
echo "<?php phpinfo(); ?>" > /var/www/php72/index.php

Let’s start the creation of VirtualHost and edit in your favorite text editor:

nano /etc/apache2/sites-available/php56.example.com.conf

Add the following content:

<VirtualHost *:80>
ServerName php56.example.com
DocumentRoot /var/www/php56
<Directory /var/www/php56>
Options -Indexes +FollowSymLinks +MultiViews
AllowOverride All
Require all granted
</Directory>
<FilesMatch \.php$>
# Apache 2.4.10+ can proxy to unix socket
SetHandler "proxy:unix:/var/run/php/php5.6-fpm.sock|fcgi://localhost/"
</FilesMatch>
</VirtualHost>

Then, create a second VirtualHost configuration file to work with PHP 7.2:

nano /etc/apache2/sites-available/php72.example.com.conf

Add the following content:

<VirtualHost *:80>
ServerName php72.example.com
DocumentRoot /var/www/php72
<Directory /var/www/php72>
Options -Indexes +FollowSymLinks +MultiViews
AllowOverride All
Require all granted
</Directory>
<FilesMatch \.php$>
SetHandler "proxy:unix:/var/run/php/php7.2-fpm.sock|fcgi://localhost/"
</FilesMatch>
</VirtualHost>

Create a symbolic link of config files to this directory or use below command:

sudo a2ensite php56.example.com
sudo a2ensite php72.example.com
sudo a2enmod actions fastcgi alias proxy_fcgi

After making all the changes restart Apache to reload new settings changes:

systemctl restart apache2

Step 4. Test Multiple PHP Version.

Try to access it at php56.example.com shows the version PHP 5.6 and php72.example.com is showing the PHP 7.2 . If the PHP info page is rendered in your browser then everything looks good and you are ready to proceed further.

Congratulation’s! You have successfully installed Multiple PHP Version. Thanks for using this tutorial for installing Multiple PHP on Ubuntu 18.04 LTS (Bionic Beaver) system. For additional help or useful information, we recommend you to check the official PHP web site.
