+==== 1 Red Hat Enterprise Linux/CentOS ====
+==== Overview ====
+Official Zabbix packages are available for:
+|RHEL 8, CentOS 8 and Oracle Linux 8  |[[https://www.zabbix.com/download?zabbix=5.4&os_distribution=red_hat_enterprise_linux&os_version=8&db=mysql|Download]]  |
+Packages are available with either MySQL/PostgreSQL database and Apache/Nginx webserver support.
+<note important>Zabbix 5.4 is not released yet. The download links lead to pre-5.4 packages.</note>
+//Zabbix agent// packages and utilities //Zabbix get// and //Zabbix sender// are available for [[https://repo.zabbix.com/zabbix/5.4/rhel/7/x86_64/|RHEL 7]], [[https://repo.zabbix.com/zabbix/5.4/rhel/6/x86_64/|RHEL 6]] and [[https://repo.zabbix.com/zabbix/5.4/rhel/5/x86_64|RHEL 5]] as well.
+Zabbix official repository provides fping and libssh2 packages as well. These packages are located in the [[https://repo.zabbix.com/non-supported/|non-supported]] directory.
+==== Notes on installation ====
+See [[https://www.zabbix.com/download?zabbix=5.0&os_distribution=red_hat_enterprise_linux&os_version=8&db=mysql|installation instructions]] per platform in the download page for:
+  * installing the repository
+  * installing server/agent/frontend
+  * creating initial database, importing initial data
+  * configuring database for Zabbix server
+  * configuring PHP for Zabbix frontend
+  * starting server/agent processes
+  * configuring Zabbix frontend
+If you want to run Zabbix agent as root, see [[https://www.zabbix.com/documentation/5.0/manual/appendix/install/run_agent_as_root|Running agent as root]].
+=== Importing data with Timescale DB ===
+With TimescaleDB, in addition to the import command for PostgreSQL, also run:
+  # zcat /usr/share/doc/zabbix-server-pgsql*/timescaledb.sql.gz | sudo -u zabbix psql zabbix
+<note warning>TimescaleDB is supported with Zabbix server only.</note>
+=== PHP 7.2 ===
+Zabbix frontend requires PHP version **7.2 or newer**.
+=== SELinux configuration ===
+Having SELinux status enabled in enforcing mode, you need to execute the following commands to enable communication between Zabbix frontend and server:
+RHEL 7 and later:
+  # setsebool -P httpd_can_connect_zabbix on
+  If the database is accessible over network (including 'localhost' in case of PostgreSQL), you need to allow Zabbix frontend to connect to the database too:
+  # setsebool -P httpd_can_network_connect_db on
+RHEL prior to 7:
+  # setsebool -P httpd_can_network_connect on
+  # setsebool -P zabbix_can_network on
+After the frontend and SELinux configuration is done, restart the Apache web server:
+  # service httpd restart
+==== Proxy installation ====
+Once the required repository is added, you can install Zabbix proxy by running:
+  # dnf install zabbix-proxy-mysql
+Substitute 'mysql' in the commands with 'pgsql' to use PostgreSQL, or with 'sqlite3' to use SQLite3 (proxy only).
+== Creating database ==
+[[:manual/appendix/install/db_scripts|Create]] a separate database for Zabbix proxy.
+Zabbix server and Zabbix proxy cannot use the same database. If they are installed on the same host, the proxy database must have a different name.
+== Importing data ===
+Import initial schema:
+  # zcat /usr/share/doc/zabbix-proxy-mysql*/schema.sql.gz | mysql -uzabbix -p zabbix
+For proxy with PostgreSQL (or SQLite):
+  # zcat /usr/share/doc/zabbix-proxy-pgsql*/schema.sql.gz | sudo -u zabbix psql zabbix
+  # zcat /usr/share/doc/zabbix-proxy-sqlite3*/schema.sql.gz | sqlite3 zabbix.db
+== Configure database for Zabbix proxy ==
+Edit zabbix_proxy.conf:
+  # vi /etc/zabbix/zabbix_server.conf
+  DBHost=localhost
+  DBName=zabbix
+  DBUser=zabbix
+  DBPassword=<password>
+In DBName for Zabbix proxy use a separate database from Zabbix server.
+In DBPassword use Zabbix database password for MySQL; PosgreSQL user password for PosgreSQL.
+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. See [[:manual/installation/install_from_packages/rhel_centos#selinux_configuration|SELinux configuration]] for instructions.
+== Starting Zabbix proxy process ==
+To start a Zabbix proxy process and make it start at system boot:
+  # service zabbix-proxy start
+  # systemctl enable zabbix-proxy
+== Frontend configuration ==
+A Zabbix proxy does not have a frontend; it communicates with Zabbix server only.
+==== Java gateway installation ====
+It is required to install [[:manual/concepts/java|Java gateway]] only if you want to monitor JMX applications. Java gateway is lightweight and does not require a database.
+Once the required repository is added, you can install Zabbix Java gateway by running:
+  # dnf install zabbix-java-gateway
+Proceed to [[:manual/concepts/java/from_rhel_centos|setup]] for more details on configuring and running Java gateway.
+==== Installing debuginfo packages ====
+<note> Debuginfo packages are currently available for RHEL/CentOS versions 7, 6 and 5. </note>
+To enable debuginfo repository edit ///etc/yum.repos.d/zabbix.repo// file.
+Change ''enabled=0'' to ''enabled=1'' for zabbix-debuginfo repository.
+  [zabbix-debuginfo]
+  name=Zabbix Official Repository debuginfo - $basearch
+  baseurl=http://repo.zabbix.com/zabbix/5.4/rhel/8/$basearch/debuginfo/
+  enabled=0
+  gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
+  gpgcheck=1
+This will allow you to install the zabbix-debuginfo package.
+  # yum install zabbix-debuginfo
+This single packages contains debug information for all binary Zabbix componets.
