3 SUSE Linux Enterprise Server

Overview

Official Zabbix 7.2 PRE-RELEASE packages for SUSE Linux Enterprise Server are available on Zabbix website. Note that Zabbix 7.2 is not released yet and provided packages are for the Zabbix version that is currently being developed.

Zabbix agent packages and utilities Zabbix get and Zabbix sender are available in Zabbix Official Repository for SLES 15 (SP4 and newer) and SLES 12 (SP4 and newer) as 7.2 pre-release versions.

Please note that SLES 12 can be used only for Zabbix proxy and the following features are not available:

• Verify CA encryption mode with MySQL does not work due to older MySQL libraries.
• SSH checks - due to the older libssh version.

Adding Zabbix repository

Install the repository configuration package. This package contains yum (software package manager) configuration files.

SLES 15:

rpm -Uvh --nosignature https://repo.zabbix.com/zabbix/7.2/release/sles/15/noarch/zabbix-release-latest.sles15.noarch.rpm
       zypper --gpg-auto-import-keys refresh 'Zabbix Official Repository' 

SLES 12 (proxy only):

rpm -Uvh --nosignature https://repo.zabbix.com/zabbix/7.2/release/sles/12/noarch/zabbix-release-latest.sles12.noarch.rpm
       zypper --gpg-auto-import-keys refresh 'Zabbix Official Repository' 

Please note that Zabbix web service process, which is used for scheduled report generation, requires Google Chrome browser. The browser is not included into packages and has to be installed manually.

Server/frontend/agent installation

To install Zabbix server/frontend/agent with PHP 8, Apache and MySQL support, run:

zypper install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf-php8 zabbix-agent

Substitute component names in this command as needed:

• For Nginx: use zabbix-nginx-conf-php8 instead of zabbix-apache-conf-php8. See also: Nginx setup for Zabbix on SLES 15.
• For PostgreSQL: use zabbix-server-pgsql instead of zabbix-server-mysql; use zabbix-web-pgsql instead of zabbix-web-mysql.
• For Zabbix agent 2 (only SLES 15): use zabbix-agent2 instead of or in addition to zabbix-agent.

To install Zabbix proxy with MySQL support:

zypper install zabbix-proxy-mysql zabbix-sql-scripts

For PostgreSQL, use zabbix-proxy-pgsql instead of zabbix-proxy-mysql.

For SQLite3, use zabbix-proxy-sqlite3 instead of zabbix-proxy-mysql.

The package 'zabbix-sql-scripts' contains database schemas for all supported database management systems for both Zabbix server and Zabbix proxy and will be used for data import.

Creating database

Zabbix server and proxy daemons require a database. Zabbix agent does not need a database.

To create a database, follow the instructions for MySQL or PostgreSQL. An SQLite3 database (supported for Zabbix proxy only) will be created automatically and does not require additional installation steps.

Importing data

Now import initial schema and data for the server with MySQL:

zcat /usr/share/packages/zabbix-sql-scripts/mysql/create.sql.gz | mysql -uzabbix -p zabbix

You will be prompted to enter your newly created database password.

With PostgreSQL:

zcat /usr/share/packages/zabbix-sql-scripts/postgresql/create.sql.gz | sudo -u zabbix psql zabbix

With TimescaleDB, in addition to the previous command, also run:

zcat /usr/share/packages/zabbix-sql-scripts/postgresql/timescaledb/schema.sql.gz | sudo -u <username> psql zabbix

For proxy, import initial schema:

zcat /usr/share/packages/zabbix-sql-scripts/mysql/schema.sql.gz | mysql -uzabbix -p zabbix

For proxy with PostgreSQL:

zcat /usr/share/packages/zabbix-sql-scripts/postgresql/schema.sql.gz | sudo -u zabbix psql zabbix

Configure database for Zabbix server/proxy

Edit Zabbix server configuration file (/etc/zabbix/zabbix_server.conf) and, if required, Zabbix proxy configuration file (/etc/zabbix/zabbix_proxy.conf) for their respective databases. For example:

DBHost=localhost
       DBName=zabbix
       DBUser=zabbix
       DBPassword=<password>

In DBPassword use Zabbix database password for MySQL; PostgreSQL user password for PostgreSQL.

Use DBHost= with PostgreSQL. You might want to keep the default setting DBHost=localhost (or an IP address), but this would make PostgreSQL use a network socket for connecting to Zabbix.

Zabbix frontend configuration

Depending on the web server used (Apache/Nginx), edit the corresponding configuration file for Zabbix frontend. While some PHP settings may already be configured, it's essential that you uncomment the date.timezone setting and specify the appropriate timezone setting that suits your requirements.

• For Apache the configuration file is located in /etc/apache2/conf.d/zabbix.conf.

    php_value max_execution_time 300
           php_value memory_limit 128M
           php_value post_max_size 16M
           php_value upload_max_filesize 2M
           php_value max_input_time 300
           php_value max_input_vars 10000
           php_value always_populate_raw_post_data -1
           # php_value date.timezone Europe/Riga

• The zabbix-nginx-conf package installs a separate Nginx server for Zabbix frontend. Its configuration file is located in /etc/nginx/conf.d/zabbix.conf. For Zabbix frontend to work, it's necessary to uncomment and set listen and/or server_name directives.

    # listen 80;
           # server_name example.com;

• Zabbix uses its own dedicated php-fpm connection pool with Nginx:

Its configuration file is located in /etc/php8/fpm/php-fpm.d/zabbix.conf (the path may vary slightly depending on the service pack).

    php_value[max_execution_time] = 300
           php_value[memory_limit] = 128M
           php_value[post_max_size] = 16M
           php_value[upload_max_filesize] = 2M
           php_value[max_input_time] = 300
           php_value[max_input_vars] = 10000
           ; php_value[date.timezone] = Europe/Riga

Now you are ready to proceed with frontend installation steps that will allow you to access your newly installed Zabbix.

Note that a Zabbix proxy does not have a frontend; it communicates with Zabbix server only.

Starting Zabbix server/agent process

Start Zabbix server and agent processes and make it start at system boot.

With Apache web server:

systemctl restart zabbix-server zabbix-agent apache2 php-fpm
       systemctl enable zabbix-server zabbix-agent apache2 php-fpm

For Nginx, substitute apache2 with nginx.

Installing debuginfo packages

To enable debuginfo repository edit /etc/zypp/repos.d/zabbix.repo file. Change enabled=0 to enabled=1 for zabbix-debuginfo repository.

    [zabbix-debuginfo]
           name=Zabbix Official Repository debuginfo
           type=rpm-md
           baseurl=https://repo.zabbix.com/zabbix/7.2/stable/sles/15/x86_64/debuginfo/
           gpgcheck=1
           gpgkey=https://repo.zabbix.com/zabbix/7.2/stable/sles/15/x86_64/debuginfo/repodata/repomd.xml.key
           enabled=0
           update=1

This will allow you to install zabbix-<component>-debuginfo packages.
