Zabbix 5 has a lot of GUI imrovment and other new features, notice the installation on CentOS 8 is a little different. lets start .<\/p>\n

If you are a fan of SELinux you can set it to permissive mode :<\/p>\n

setenforce 0 && sed -i 's\/^SELINUX=.*\/SELINUX=permissive\/g' \/etc\/selinux\/config

To disable just edit with #nano \/etc\/selinux\/config 

And set :  SELINUX=disabled<\/code><\/pre>\n
Next install libssh2.so.1 which is needed by zabbix 5<\/p>\n
To use libssh2 you must enable the EPEL repo. After that libssh2 can be installed<\/p>\n
yum install epel-release\n\nyum install libssh2<\/pre>\n
In case of develop environment you can install the libssh2-devel<\/p>\n
yum install libssh2-devel<\/pre>\n
Then install zabbix<\/p>\n
rpm -Uvh https:\/\/repo.zabbix.com\/zabbix\/5.4\/rhel\/8\/x86_64\/zabbix-release-5.4-1.el8.noarch.rpm<\/span>
dnf clean all<\/span>
dnf -y install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-agent zabbix-sql-scripts<\/span><\/pre>\n
Now we have to add mysql server = mariaDB<\/p>\n
dnf -y install mariadb-server && systemctl start mariadb && systemctl enable mariadb<\/span><\/pre>\n
configure the mysql server :<\/p>\n
If your environment is going to monitor a lot of host , I recommend using MySQL database with file for each table, this option is going to help in reducing the database size in the future as the table can be controlled and all the data is spread. in the default setting the data is in one file ibdata1 which can be very big. So edit the file \/etc\/my.cnf :<\/p>\n
[mysqld]
innodb_file_per_table<\/pre>\n


So Lets continue :<\/span>


mysql_secure_installation<\/span><\/pre>\n
Create User & DB (notice the charset = utf8 which is required by zabbix 5)<\/p>\n
mysql -u root -p<\/span>
create database zabbix_db character set utf8 collate utf8_bin;<\/span>
grant all privileges on zabbix_db.* to zabbix_user@localhost identified by 'zabbix' ;<\/span>
flush privileges;<\/span>
show create database zabbix_db;<\/span>\u00a0\u00a0\u00a0\u00a0 ->to make sure db is created O.K<\/span>
exit<\/span><\/pre>\n
Temporary disable strict mode (ZBX-16465) to avoid MySQL error \u201cERROR 1118 (42000) at line 1284: Row size too large (> 8126)\u201d :
#mysql -uroot -p'your_password you set for mysql' zabbix_db -e \"set global innodb_strict_mode='OFF';\"<\/span><\/pre>\n
build database :
#zcat \/usr\/share\/doc\/zabbix-sql-scripts\/mysql\/create.sql.gz | mysql zabbix_db -uzabbix_user -pzabbix

<\/span>re-enable stric mode:
#mysql -uroot -p'your_password you set for mysql' zabbix_db -e \"set global innodb_strict_mode='ON';\"<\/span><\/pre>\n
configure Zabbix for the database we have prepared for it :<\/p>\n
#nano \/etc\/zabbix\/zabbix_server.conf<\/span>
DBname=zabbix_db<\/span>
DBuser=zabbix_user<\/span>
DBPassword=zabbix<\/span><\/pre>\n
Start zabbix<\/p>\n
#systemctl restart zabbix-server zabbix-agent <\/span>
#systemctl enable zabbix-server zabbix-agent<\/span><\/pre>\n
Add firewall rules<\/p>\n
#firewall-cmd --add-service={http,https} --permanent<\/span>
#firewall-cmd --add-port={10051\/tcp,10050\/tcp} --permanent<\/span>
#firewall-cmd --reload<\/span><\/pre>\n
Now lets start configure the web frontend<\/p>\n
#nano \/etc\/php-fpm.d\/zabbix.conf<\/span>
php_value date.timezone Asia\/Jerusalem<\/span><\/pre>\n
restart the website service :<\/p>\n
#systemctl restart httpd php-fpm<\/span>
#systemctl enable httpd php-fpm<\/span><\/pre>\n
Thats it ! Now open a browser and surf to<\/p>\n
http:\/\/your_zabbix_server_IP\/zabbix<\/span><\/pre>\n
Enter this variables 
Database name : zabbix_db<\/span>
user : zabbix_user<\/span>
Password : zabbix<\/span><\/pre>\n
default user name : Admin\u00a0\u00a0 Password: zabbix<\/h4>\n
Now you are done! enjoy<\/h4>\n
\n
Good Luck<\/h3>\n\n\n
