Open the PHP configuration file,php.ini using your favourite text editor.<\/p>\n<p>Here i am using nano editor. If you do not have nano installed, you can run<\/p>\n<pre>yum -y install nano.\r\nnano \/etc\/php.ini<\/pre>\n<p>Find the following line and Uncomment the line and set the timezone according to your region. For example:<\/p>\n<pre>[Date]\r\nDefines the default timezone used by the date functions\r\nhttp:\/\/php.net\/date.timezone\r\ndate.timezone = Asia\/Kolkata<\/pre>\n<h4>Step 3 - Installing MariaDB<\/h4>\n<p>MariaDB is a fork of MySQL database. To install MariaDB on your server, run:<\/p>\n<pre>yum -y install mariadb mariadb-server<\/pre>\n<p>Enter and execute the following commands to start MariaDB and enable it to start at boot time.<\/p>\n<pre>systemctl start mariadb\r\nsystemctl enable mariadb<\/pre>\n<p>Now run the following commands to secure your MariaDB installation.<\/p>\n<pre>mysql_secure_installation<\/pre>\n<p>The above command will run a script to secure fresh MariaDB installation. The script will ask for the existing root user password, we have just installed MariaDB, the root password is not set, just press enter to proceed further.<br \/>\nNow we want to set a root password for the MariaDB installation, choose y and set a strong password for the installation. The output will look like shown below.<br \/>\nTo create a database we will need to login to MySQL command line first. Run the following command for same.<\/p>\n<pre>mysql -u root -p<\/pre>\n<p>The above command will login to MySQL shell of the root user, it will prompt for the password of the root user. Provide the password to login. Now run the following query to create a new database for your Cacti installation.<\/p>\n<pre>CREATE DATABASE enter the database name (xxxxxxxx);<\/pre>\n<p>The above query will create a new database named xxxxxxxx. We can use any other name for our database if we want. Make sure that you use semicolon at the end of each query as the query always ends with a semicolon.<br \/>\nOnce the database is created you can create a new user and grant all the permissions to the user for the database. To create a new database user, run the following query.<\/p>\n<pre>CREATE USER '123456789'@'localhost' IDENTIFIED BY 'Password';<\/pre>\n<p>The above query will create a user with username 123456789. You can use any username you prefer instead of 123456789. Replace Password with a very strong password as your wish. Now provide the all the privileges to your database user over the database you have created. Run the following command.<\/p>\n<pre>GRANT ALL PRIVILEGES ON xxxxxxxx* TO '123456789'@'localhost';<\/pre>\n<p>Now run the following command to immediately apply the changes on the database privileges.<\/p>\n<pre>FLUSH PRIVILEGES;<\/pre>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-672\" src=\"https:\/\/www.coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/mysql-database.jpg\" alt=\"\" width=\"846\" height=\"229\" srcset=\"https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/mysql-database.jpg 846w, https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/mysql-database-300x81.jpg 300w, https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/mysql-database-768x208.jpg 768w\" sizes=\"auto, (max-width: 846px) 100vw, 846px\" \/><\/p>\n<p>Exit from MySQL prompt using the following command.<\/p>\n<pre>EXIT;<\/pre>\n<p>You will also need to populate the time zone table.

Once the tables are populated, you will need to provide select access to Cacti user account over the tables. Login to MySQL prompt again using:<\/p>\n<pre>mysql -u root -p<\/pre>\n<p>Now run the following query.<\/p>\n<pre>GRANT SELECT ON mysql.time_zone_name TO '123456789'@'localhost';\r\nFLUSH PRIVILEGES;<\/pre>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-673\" src=\"https:\/\/www.coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/mysql-time-zone.jpg\" alt=\"\" width=\"794\" height=\"128\" srcset=\"https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/mysql-time-zone.jpg 794w, https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/mysql-time-zone-300x48.jpg 300w, https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/mysql-time-zone-768x124.jpg 768w\" sizes=\"auto, (max-width: 794px) 100vw, 794px\" \/><\/p>\n<p>The above query will SELECT give access to cacti_user on<\/p>\n<h2 lang=\"zxx\"><span style=\"font-size: medium;\">Step 4 - Installing and Configuring Cacti<\/span><\/h2>\n<p>Cacti require few more dependencies, run the following command to install them.<\/p>\n<pre>yum -y install net-snmp rrdtool net-snmp-utils<\/pre>\n<p>As we have all the dependencies ready, we can now download the install package from Cacti website.<\/p>\n<pre>cd \/var\/www\/html\r\nwget http:\/\/www.cacti.net\/downloads\/cacti-1.1.10.tar.gz<\/pre>\n<p>You can always find the link to the latest version of the <a  href=\"https:\/\/coimbatorewebhosting.com\/blog\/what-is-an-operating-systemlinux\/\" title=\"application\" alt=\"application\">application<\/a> on <a href=\"http:\/\/www.cacti.net\/download_cacti.php\" rel=\"nofollow noopener\" target=\"_blank\">Cacti download page<\/a>.

Run the following commands for same.<\/p>\n<pre>firewall-cmd --zone=public --permanent --add-service=http\r\nfirewall-cmd --reload<\/pre>\n<p>Now you will need to disable your SELinux because Proxy configuration does not work with SELinux policies. To temporary disable SELinux without restarting the server, run the following command.<\/p>\n<pre>setenforce 0<\/pre>\n<p>To completely disable the SELinux you will need to edit \/etc\/selinux\/config file.<\/p>\n<pre>nano \/etc\/selinux\/config<\/pre>\n<p>Find the following line:<\/p>\n<pre>SELINUX=enforcing<\/pre>\n<p>Change it to:<\/p>\n<pre>SELINUX=disabled<\/pre>\n<p>Now complete the installation using a web browser, go to the following link using your favourite web browser.<\/p>\n<pre>http:\/\/Your_Server_IP\/cacti<\/pre>\n<p>Now we will see the following page.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-678\" src=\"https:\/\/www.coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/cacti1-install.jpg\" alt=\"\" width=\"1357\" height=\"692\" srcset=\"https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/cacti1-install.jpg 1357w, https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/cacti1-install-300x153.jpg 300w, https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/cacti1-install-768x392.jpg 768w, https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/cacti1-install-1024x522.jpg 1024w\" sizes=\"auto, (max-width: 1357px) 100vw, 1357px\" \/><\/p>\n<p lang=\"zxx\">Accept the license agreement for further process.<\/p>\n<p lang=\"zxx\">In next interface we are going for pre-installation, all the required dependencies are met.<\/p>\n<p lang=\"zxx\">In installation type, choose <strong>New Primary Server <\/strong>and proceed next.<\/p>\n<p lang=\"zxx\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-679\" src=\"https:\/\/www.coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/catci-pre-install.jpg\" alt=\"\" width=\"1360\" height=\"687\" srcset=\"https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/catci-pre-install.jpg 1360w, https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/catci-pre-install-300x152.jpg 300w, https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/catci-pre-install-768x388.jpg 768w, https:\/\/coimbatorewebhosting.com\/blog\/wp-content\/uploads\/2017\/08\/catci-pre-install-1024x517.jpg 1024w\" sizes=\"auto, (max-width: 1360px) 100vw, 1360px\" \/><\/p>\n<p lang=\"zxx\">In next step, we want to provide the locations to the binaries.
