How To Install Zabbix Server On Centos 7

Zabbix is an Open Source, high-level enterprise software designed to monitor and keep rail of networks, servers, and applications in real-time. Build in a server-customer model, Zabbix tin collect unlike types of information that are used to create historical graphics and output operation or load trends of the monitored targets.

The server has the ability to check standard networking services (HTTP, FTP, SMTP, IMAP, etc) without the need to install extra software on the monitored hosts.

However, in order to assemble data and create statistics near local services or other specific system resource that run on remote instances, such as CPU, disks, internal system process, RAM, etc, you need to install and configure a Zabbix amanuensis.

Following are the 4-commodity series near the Zabbix Monitoring awarding:

Part 1: Install Zabbix on Debian/Ubuntu and RHEL/CentOS/Fedora/Rocky Linux/AlmaLinux

This tutorial will focus on how to install the latest version of the Zabbix Server on Debian/Ubuntu and RHEL/CentOS /Fedora/Rocky Linux/AlmaLinux with MySQL/MariaDB backend database to shop nerveless data, PHP and Apache Web Server every bit the mainly web interface.

Of import: The given Zabbix instructions as well piece of work on all Debian derivatives and RedHat-based distros similar RHEL/CentOS/Fedora and Rocky Linux/AlmaLinux.

Step 1: Install Apache Web Server and PHP

i. First, update the software packages so install Apache Spider web Server alongside PHP and its extensions in guild to provide the web-backed functionality for Zabbix Server by issuing the post-obit command.

          --------------- On Debian/Ubuntu ---------------          $ sudo apt update && sudo apt upgrade $ sudo apt install apache2 php php-mysql php-mysqlnd php-ldap php-bcmath php-mbstring php-gd php-pdo php-xml libapache2-mod-php          --------------- On RHEL-based Distros ---------------          # yum update && yum upgrade # yum -y install epel-release # yum install httpd php php-mysqlnd php-ldap php-bcmath php-mbstring php-gd php-xml

two. Side by side, you demand to tune the PHP interpreter and adjust some values in club to run Zabbix Server. So, open up Apache php.ini configuration file for editing by issuing the following command:

$ sudo nano /etc/php/vii.X/apache2/php.ini 	[On          Debian/Ubuntu]  # 6 /etc/php.ini				[On          RHEL/CentOS/]

Now, search with CTRL+C and replace the following PHP values as it follows:

post_max_size = 16M upload_max_filesize = 2M max_execution_time 300 max_input_time = 300 memory_limit 128M session.auto_start = 0 mbstring.func_overload = 0 appointment.timezone = Europe/Bucharest

Replace the appointment.timezone variable according to your server's geographical location. A list of PHP-supported Timezones tin exist plant here http://php.net/manual/en/timezones.php.

3. After updating the PHP configuration file, restart Apache daemon to reflect changes by issuing the following command.

$ sudo systemctl restart apache2.service	 [On          Debian/Ubuntu]  # systemctl restart httpd.service		 [On          RHEL/CentOS]

Footstep 2: Install MariaDB Database and Library

4. On the next footstep install the MariaDB database and MySQL development library from binary packages. Every bit MariaDB installs on your system y'all will be asked to prepare a password for the database root user during installation (Only on Debian). Choose a strong password, echo it and wait for the installation to stop.

$ sudo apt-become install mariadb-server mariadb-client libmysqld-dev	 [On          Debian/Ubuntu]  # yum install mariadb-server mariadb-client mariadb-devel	         [On          RHEL/CentOS]

Set MySQL root Password — Set MySQL root Countersign

5. When the installation of Mariadb finishes, start and secure the database by issuing mysql_secure_installation command with system root privileges ( answer with yeah for removing anonymous users, disable root login remotely, remove test database and access to information technology and employ all changes).

$ sudo systemctl start mariadb $ sudo mysql_secure_installation OR # systemctl offset mariadb # mysql_secure_installation

Use the below screenshot as a guide.

Secure MySQL Installation

vi. The next requirement for Zabbix is setting upwardly an RDBMS database. Log in to your LAMP stack database component (MySQL or MariaDB) and create a Zabbix database and the credentials required to manage the database, past issuing the post-obit commands.

Brand sure you replace the database name, user, and password to match your own settings.

# mysql -u root -p          MariaDB [(none)]>          create database zabbixdb character ready utf8 collate utf8_bin;          MariaDB [(none)]>          grant all privileges on zabbixdb.* to 'zabbixuser'@'localhost' identified by 'password1';          MariaDB [(none)]>          flush privileges;          MariaDB [(none)]>          exit

Step 3: Install Zabbix Server
