New installation from packages for RedHat / CentOS / Oracle Linux 7

1. Install DBService repository

If you are using Oracle Linux 7, then enable ol7_optional_latest and ol7_developer_EPEL repository

yum-config-manager --enable ol7_optional_latest
yum-config-manager --enable ol7_developer_EPEL

If you are using RedHat 7, then enable rhel-7-server-optional-rpms repository

yum-config-manager --enable rhel-7-server-optional-rpms

If you are using CentOS 7, then enable EPEL repository

yum localinstall https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

Install repository

yum localinstall https://repo.programs74.ru/zabbix/4.4/rhel/7/x86_64/dbs-release-4.4-1.el7.noarch.rpm
sed -i "s/dbservice.tech/programs74.ru/g" /etc/yum.repos.d/dbs.repo
yum clean all
yum makecache fast

2. Install Zabbix server (with MySQL support), agent

yum install zabbix-server-mysql zabbix-agent

3. Install web-frontend

with Apache support

yum install httpd httpd-tools
yum install zabbix-web-mysql
systemctl enable httpd.service
systemctl start httpd.service

with Nginx + PHP-FPM support

yum install nginx
yum install zabbix-web-mysql zabbix-nginx-conf php-fpm
systemctl enable nginx.service
systemctl start nginx.service

You need to execute these commands, If you have enabled SELinux in "enforcing" mode

setsebool -P httpd_can_connect_zabbix on
setsebool -P httpd_can_network_connect_db on

Create SELinux rules for Zabbix-server:

yum install policycoreutils-devel

(cat <<-EOF
module zabbixserver 1.0;

require {
        type mysqld_db_t;
        type zabbix_t;
        type zabbix_var_run_t;
        class capability dac_override;
        class sock_file { create write unlink };
	class unix_stream_socket connectto;
}

#============= zabbix_t ==============

#!!!! This avc is allowed in the current policy
allow zabbix_t self:capability dac_override;

#!!!! This avc is allowed in the current policy
allow zabbix_t mysqld_db_t:sock_file write;

#!!!! This avc can be allowed using the boolean 'daemons_enable_cluster_mode'
allow zabbix_t self:unix_stream_socket connectto;

#!!!! This avc is allowed in the current policy
allow zabbix_t zabbix_var_run_t:sock_file create;
allow zabbix_t zabbix_var_run_t:sock_file write;
allow zabbix_t zabbix_var_run_t:sock_file unlink;
EOF
)>/root/zabbixserver.te

semodule -r zabbixserver 2>/dev/null
rm -f /root/zabbixserver.mod /root/zabbixserver.pp
checkmodule -M -m -o /root/zabbixserver.mod /root/zabbixserver.te
semodule_package -o /root/zabbixserver.pp -m /root/zabbixserver.mod
semodule -i /root/zabbixserver.pp

Allow port 80 for Apache/Nginx service and allow port 10050/10051 for Zabbix agent and Zabbix server through out the system firewall

firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --add-service=https
firewall-cmd --permanent --add-port=80/tcp
firewall-cmd --permanent --add-port=443/tcp
firewall-cmd --permanent --add-port=10050/tcp
firewall-cmd --permanent --add-port=10051/tcp
firewall-cmd --reload

4. Create and initial Zabbix database

Run the following on your database host::

# mysql -uroot -p
password: *******
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by 'password';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> flush privileges;
mysql> quit;

On Zabbix server host import initial schema and data:

# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -ppassword zabbix

5. Configure the database for Zabbix server

Edit file /etc/zabbix/zabbix_server.conf

DBPassword=password

6. Configure PHP for Zabbix frontend

If use Apache web-server:

Edit file /etc/httpd/conf.d/zabbix.conf, uncomment and set the right timezone for you.

php_value date.timezone Europe/Riga

Restart Apache web-server

systemctl restart httpd

If use Nginx + PHP-FPM:

Edit file /etc/php-fpm.d/zabbix.conf, uncomment and set the right timezone for you

php_value[date.timezone] = Europe/Riga

Start php-fpm processes and make it start at system boot

systemctl enable php-fpm
systemctl start php-fpm

Edit Nginx config file /etc/nginx/conf.d/zabbix.conf and change listen and server_name settings

listen          80;
server_name     <enter your domain>;

Restart Nginx web-server

nginx -t && nginx -s reload

7. Start Zabbix server and agent processes

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

systemctl enable zabbix-server zabbix-agent
systemctl restart zabbix-server zabbix-agent

8. Configure Zabbix frontend

Connect to your newly installed Zabbix frontend:

If use Apache: http://server_ip_or_name/zabbix

If use Nginx: http://server_ip_or_name

Follow steps described in official Zabbix documentation: Installing frontend
