Zabbix<\/strong>\u00a0is an Open Source, high-level enterprise software designed to monitor and keep track of networks, servers and applications in real time. Build in a server-client model, Zabbix can collect different type of data than are used to create historical graphics and output performance or load trends of the monitored targets.<\/p>\n

The server has the ability to check standard networking services (HTTP<\/strong>,\u00a0FTP<\/strong>,\u00a0SMTP<\/strong>,\u00a0IMAP<\/strong>\u00a0etc) without the need to install extra software on the monitored hosts.<\/p>\n

However, in order to gather data and create statistics about local services or other specific system resources that run on remote instances, such as CPU, disks, internal system process, RAM, etc, you need to install and configure a Zabbix agent.<\/p>\n

This tutorial will focus on how to install latest version of\u00a0Zabbix 3.4 Server<\/strong>\u00a0on\u00a0Debian\/Ubuntu<\/strong>\u00a0and\u00a0RHEL<\/strong>\/CentOS 7<\/strong>\u00a0with MySQL\/MariaDB backend database to store collected data, PHP and Apache Web Server as the mainly web interface.<\/p>\n

Important:<\/strong>\u00a0The given Zabbix instructions also works on all\u00a0Debian<\/strong>\u00a0derivatives and\u00a0RedHat<\/strong>\u00a0based systems like\u00a0RHEL<\/strong>\/CentOS<\/strong>\u00a0and\u00a0Fedora<\/strong>.<\/p>\n

Step 1: Install Apache Web Server and PHP<\/h3>\n

1.<\/strong>\u00a0First, install\u00a0Apache Web Server<\/strong>\u00a0alongside with\u00a0PHP<\/strong>\u00a0and its extensions in order to provide the web backed functionality for Zabbix Server by issuing the following command.<\/p>\n

--------------- On Debian\/Ubuntu ---------------<\/strong> \r\n$ sudo apt-get install apache2 php7.0 php7.0-mysql php7.0-ldap php7.0-bcmath php7.0-mbstring php7.0-gd php7.0-xml php7.0-mcrypt\r\n\r\n--------------- On CentOS\/RHEL ---------------<\/strong>\r\n# yum -y install epel-release\r\n# yum install httpd php php-mysql php-ldap php-bcmath- php-mbstring php-gd php-xml php-mcrypt\t\t\r\n<\/pre>\n
2.<\/strong>\u00a0Next, you need to tune PHP interpreter and adjust some values in order to run Zabbix Server. So, open Apache\u00a0php.ini<\/code>\u00a0configuration file for editing by issuing the following command:<\/p>\n
$ sudo nano \/etc\/php\/7.0\/apache2\/php.ini \t[On Debian\/Ubuntu<\/strong>] \r\n# vi \/etc\/php.ini\t\t\t\t[On RHEL\/CentOS 7<\/strong>]\r\n<\/pre>\n
Now, search with\u00a0CTRL+C<\/strong>\u00a0and replace the following PHP values as it follows:<\/p>\n
max_execution_time 300\r\nmemory_limit 128M\r\nalways_populate_raw_post_data -1\r\nsession.auto_start = 0\r\nmbstring.func_overload = 0\r\ndate.timezone = Europe\/Bucharest\r\n<\/pre>\n
Replace the\u00a0date.timezone<\/strong>\u00a0variable according to your server geographical location. A list of PHP supported Timezones can be found here\u00a0http:\/\/php.net\/manual\/en\/timezones.php<\/a>.<\/p>\n
3.<\/strong>\u00a0After updating PHP configuration file, restart Apache daemon to reflect changes by issuing the following command.<\/p>\n
$ sudo systemctl restart apache2.service\t [On Debian\/Ubuntu<\/strong>] \r\n# systemctl restart httpd.service\t\t [On RHEL\/CentOS 7<\/strong>]\r\n<\/pre>\n
Step 2: Install MariaDB Database and Library<\/h3>\n
4.<\/strong>\u00a0On the next step install MariaDB database and MySQL development library from binary packages. As MariaDB installs on your system you will be asked to set a password for the database root user during installation (Only on\u00a0Debian 8\/9<\/strong>). Choose a strong password, repeat it and wait for the installation to finish.<\/p>\n
$ sudo apt-get install mariadb-server mariadb-client libmysqld-dev\t [On Debian\/Ubuntu<\/strong>] \r\n# yum install mariadb-server mariadb-client mariadb-devel\t         [On RHEL\/CentOS 7<\/strong>]\r\n<\/pre>\n
\n
\"Set<\/a><\/p>\n
Set MySQL root Password<\/p>\n<\/div>\n
5.<\/strong>\u00a0When the installation of\u00a0Mariadb<\/strong>\u00a0finishes, secure the database by issuing\u00a0mysql_secure_installation<\/strong>command with system root privileges ( answer with\u00a0yes<\/strong>\u00a0for removing anonymous users, disable root login remotely, remove test database and access to it and apply all changes).<\/p>\n
# mysql_secure_installation\r\n<\/pre>\n
Use the below screenshot as a guide.<\/p>\n
\"Secure<\/a><\/p>\n
6.<\/strong>\u00a0The next requirement for Zabbix is setting-up a 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, by issuing the following commands.<\/p>\n
Make sure you replace database name, user and password to match your own settings.<\/p>\n
# mysql -u root -p\r\nMariaDB [(none)]><\/strong> create database zabbixdb character set utf8 collate utf8_bin;\r\nMariaDB [(none)]><\/strong> grant all privileges on zabbixdb.* to 'zabbixuser'@'localhost' identified by 'password1';\r\nMariaDB [(none)]><\/strong> flush privileges;\r\nMariaDB [(none)]><\/strong> exit\r\n<\/pre>\n
Step 3: Install Zabbix Server<\/h3>\n
7.<\/strong>\u00a0Now, start to install Zabbix server and Zabbix PHP frontend application by adding the official Zabbix repositories to your system package manager by issuing the following commands with root privileges.<\/p>\n
Install Zabbix on Debian<\/h4>\n
# wget http:\/\/repo.zabbix.com\/zabbix\/3.4\/debian\/pool\/main\/z\/zabbix-release\/zabbix-release_3.4-1+stretch_all.deb \r\n# dpkg -i zabbix-release_3.4-1+stretch_all.deb\r\n# apt update\r\n# apt install zabbix-server-mysql zabbix-frontend-php \r\n<\/pre>\n
Install Zabbix on Ubuntu<\/h4>\n
# wget http:\/\/repo.zabbix.com\/zabbix\/3.4\/ubuntu\/pool\/main\/z\/zabbix-release\/zabbix-release_3.4-1+xenial_all.deb \r\n# dpkg -i zabbix-release_3.4-1+xenial_all.deb\r\n# apt-get update\r\n# apt install zabbix-server-mysql zabbix-frontend-php \r\n<\/pre>\n
Install Zabbix on CentOS<\/h4>\n
# rpm -ivh http:\/\/repo.zabbix.com\/zabbix\/3.4\/rhel\/7\/x86_64\/zabbix-release-3.4-2.el7.noarch.rpm\r\n# yum install zabbix-server-mysql zabbix-web-mysql\r\n<\/pre>\n
If you want to download and compile an older version, please visit Zabbix official\u00a0Sourceforge<\/a>\u00a0repositories.<\/p>\n
8.<\/strong>\u00a0Next, issue the below command with root privileges in order to install Zabbix agent in your system. Zabbix client will be used to actively monitor server\u2019s local system resources.<\/p>\n
# apt install zabbix-agent    [On Debian\/Ubuntu<\/strong>] \r\n# yum install zabbix-agent    [On RHEL\/CentOS 7<\/strong>] \r\n<\/pre>\n
9.<\/strong>\u00a0On the next step, restart Apache HTTP server in order to apply Zabbix configuration file installed for Apache.<\/p>\n
# systemctl restart apache2   [On Debian\/Ubuntu<\/strong>] \r\n# systemctl restart httpd     [On RHEL\/CentOS 7<\/strong>] \r\n# setenforce 0                [Disable SELinux on RHEL\/CentOS 7<\/strong>] \r\n<\/pre>\n
Step 4: Configure Zabbix Server and Agent<\/h3>\n
10.<\/strong>\u00a0Before configuring the server, first, import Zabbix initial database schema to MySQL database. Import the schema against the database created for Zabbix application, by issuing the below command.<\/p>\n
# zcat \/usr\/share\/doc\/zabbix-server-mysql\/create.sql.gz | mysql -u zabbixuser zabbixdb -p\r\n<\/pre>\n
11.<\/strong>\u00a0On the next step, setup Zabbix server by opening the main configuration file for editing with the following command.<\/p>\n
# nano \/etc\/zabbix\/zabbix_server.conf\r\n<\/pre>\n
In\u00a0zabbix_server.conf<\/strong>\u00a0file search and modify the following lines as presented in the below excerpt. Update the variables to reflect your own database settings.<\/p>\n
DBHost=localhost\r\nDBName=zabbixdb\r\nDBUser=zabbixuser\r\nDBPassword=password1\r\n<\/pre>\n
12.<\/strong>\u00a0Finally, save and close Zabbix server configuration file by pressing\u00a0Ctrl+o<\/strong>\u00a0and\u00a0Ctrl+x<\/strong>\u00a0file and restart Zabbix daemon to apply changes by issuing the below command.<\/p>\n
# systemctl restart zabbix-server.service\r\n<\/pre>\n
13.<\/strong>\u00a0Next, configure Zabbix Agent configuration file by updating the following lines. First, open the file for editing.<\/p>\n
# nano \/etc\/zabbix\/zabbix_agentd.conf \r\n<\/pre>\n
Zabbix agent configuration file excerpt:<\/p>\n
Server=127.0.0.1\r\nListenPort=10050\r\n<\/pre>\n
14.<\/strong>\u00a0Save and close Zabbix agent configuration file and restart Zabbix Agent to reflect changes by issuing the following command.<\/p>\n
# systemctl restart zabbix-agent.service \r\n<\/pre>\n
Step 5: Install and Configure Zabbix Frontend Interface<\/h3>\n
15.<\/strong>\u00a0Now it\u2019s time to install\u00a0Zabbix Server Frontend<\/strong>\u00a0web interface. In order to accomplish this step open a browser and navigate to your server IP Address using\u00a0HTTP<\/strong>\u00a0or\u00a0HTTPS<\/strong>\u00a0protocol and the welcome screen should appear. Hit the\u00a0Next<\/strong>\u00a0button to move forward.<\/p>\n
