The current Zabbix frontend requires PHP version 7.2 or higher. Unfortunately, RHEL/CentOS 7 only provides PHP 5.4 by default. This page describes the proposed method of installing Zabbix frontend on RHEL/CentOS 7.

If you do a clean installation of Zabbix 5.0 using official packages from repo.zabbix.com, you may notice that frontend packages are missing when searching for Zabbix with yum.
zabbix-agent.x86_64 : Old Zabbix Agent zabbix-get.x86_64 : Zabbix Get zabbix-java-gateway.x86_64 : Zabbix java gateway zabbix-js.x86_64 : Zabbix JS zabbix-proxy-mysql.x86_64 : Zabbix proxy for MySQL or MariaDB database zabbix-proxy-pgsql.x86_64 : Zabbix proxy for PostgreSQL database zabbix-proxy-sqlite3.x86_64 : Zabbix proxy for SQLite3 database zabbix-release.noarch : Zabbix repository configuration zabbix-sender.x86_64 : Zabbix Sender zabbix-server-mysql.x86_64 : Zabbix server for MySQL or MariaDB database zabbix-server-pgsql.x86_64 : Zabbix server for PostgreSQL database
This is due to the fact that frontend packages were moved to a dedicated
However, they can still be installed, if PHP 7.2 dependencies are provided.
For your convenience, any direct dependency on PHP has been removed from the main
zabbix-web package. This gives more flexibility in choosing the way to resolve PHP 7.2 dependency.
It is recommended to use PHP packages from Red Hat Software Collections.
To enable them run:
On Oracle Linux
# yum install scl-utils # yum install oraclelinux-release-el7 # /usr/bin/ol_yum_configure.sh # yum-config-manager --enable software_collections # yum-config-manager --enable ol7_latest ol7_optional_latest
At this point
Should return a list of new rh-php7* packages.
/etc/yum.repos.d/zabbix.repo file (if there is no such file, install zabbix-release first). Enable
At this stage searching for
yum shall return
zabbix-web package together with four new packages. These are:
zabbix-nginx-conf-scl.noarch : Zabbix frontend configuration for Nginx (scl version) zabbix-web-deps-scl.noarch : Convenience package for installing PHP dependencies of zabbix-web package from redhat software collections zabbix-web-mysql-scl.noarch : Zabbix web frontend for MySQL (scl version) zabbix-web-pgsql-scl.noarch : Zabbix web frontend for PostgreSQL (scl version)
zabbix-web-mysql-scl for MySQL or
zabbix-web-pgsql-scl package for PostgreSQL. Also install also
zabbix-nginx-conf-scl package, depending on web server used.
In Zabbix 4.4 support for Nginx was added, but the web server was not available in the official RHEL/CentOS 7 repositories. Thus, it had to be provided by the user via third-party repositores, in particular
epel. With Zabbix 5.0, if you choose to use Red Hat Software Collections, there is no need to use any third-party repositories, since Nginx is available in SCL. Simply install
This package pulls common PHP dependenencies of Zabbix frontend from Red Hat Software Collections.

It also contains php-fpm pool for Zabbix, since in this configuration frontend works through fastcgi with both Apache and Nginx.

If for some reasons Red Hat Software Collections can not be used, these alternative methods are available:

Special care must be taken during upgrade to Zabbix 5.0 from previous versions.
Packages from Red Hat Software Collections are designed to avoid conflicts with files from the main repositories.
Every such package is installed into a separate environment dedicated to its group.
For example, packages from rh-php72-php* group have their configuration installed under
/etc/opt/rh/rh-php72/ directory, logs are under
/var/opt/rh/rh-php72/log/ directory, etc. Services provided by these packages have unusual names such as
Official Zabbix 5.0 frontend packages use php-fpm with both Apache and Nginx.
This section provides Apache-specific instructions for upgrading Zabbix frontend and server from version 4.0 or 4.4 to 5.0. For Nginx-specific instructions see Upgrade process with Nginx.
Instructions below are for installing Zabbix with MySQL support. Substitute 'mysql' in the commands with 'pgsql' to use PostgreSQL
It is assumed that both frontend and server run on the same box. If you have different setup, make adjustments accordingly.
Remove old frontend
Existing Zabbix frontend must be removed before starting an upgrade. Old configuration file will be moved to
/etc/httpd/conf.d/zabbix.conf.rpmsave by rpm.
Install SCL repository
Oracle Linux run
yum install scl-utils yum install oraclelinux-release-el7 /usr/bin/ol_yum_configure.sh yum-config-manager --enable software_collections yum-config-manager --enable ol7_latest ol7_optional_latest
Install Zabbix 5.0 release package and enable zabbix-frontend repository
rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/8/x86_64/zabbix-release-5.0-1.el7.noarch.rpm yum clean all
/etc/yum.repos.d/zabbix.repo file. Replace
Install new frontend packages
Official Zabbix 5.0 frontend packages use php-fpm. Update timezone in
** Update remaining packages and restart Zabbix server**
Restarting Zabbix server will upgrade the database. Make sure the database is backed up.
** Update remaining services **
Start and enable php-fpm service.
Follow upgrade procedure for apache, described above, but make some adjustments.
A few more steps have to be performed:
Make sure to stop and disable old Nginx and php-fpm before upgrading. To do this, run:
zabbix.conf file for php-fpm, add user
zabbix-nginx-conf-scl package is installed instead of
Start and enable Nginx and php-fpm
