To install Zabbix server on Ubuntu 22.04, the following steps are required:
Step 1: Install Zabbix 6.2
sudo su
apt update && apt -y upgrade
wget https://repo.zabbix.com/zabbix/6.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.2-1+ubuntu22.04_all.deb
dpkg -i zabbix-release_6.2-1+ubuntu22.04_all.deb
apt update
root@zabbix-serverr:~# apt install -y zabbix-server-mysql zabbix-frontend-php zabbix-nginx-conf zabbix-sql-scripts zabbix-agent
Step 2: Install and configure MySQL
sudo su
apt install -y mysql-server
systemctl start mysql
systemctl enable mysql
systemctl status mysql
Step 3: Create Zabbix database and user
sudo su
mysql -uroot -p
After logging in, run the following commands to create the database and user:
create database zabbix_db character set utf8 collate utf8_bin;
create user zabbix_user@localhost identified by 'zabbix@123';
GRANT CREATE, ALTER, DROP, INSERT, UPDATE, DELETE, SELECT, REFERENCES, RELOAD on *.* TO 'zabbix_user'@'localhost' WITH GRANT OPTION;
grant all privileges on zabbix_db.* to zabbix_user@localhost;
SET GLOBAL log_bin_trust_function_creators = 1;
FLUSH PRIVILEGES;
\q
Step 4: Import Zabbix default database
sudo su
zcat /usr/share/doc/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uroot -p zabbix_db
Step 5: Find and change Zabbix configuration
Use the following command to open the Zabbix configuration file:
sudo su
nano /etc/zabbix/zabbix_server.conf
Add the following lines to the end of the file and save:
DBName=zabbix_db
DBUser=zabbix_user
DBPassword=zabbix@123
Step 6: Configure Nginx to point to the IP address of the server (in this case, 10.19.2.1)
Use the following command to open the Nginx configuration file:
sudo su
nano /etc/zabbix/nginx.conf
Find the line and change the configuration:
listen 80;
server_name 10.19.2.1
Step 7: Restart the services
sudo su
systemctl restart zabbix-server zabbix-agent nginx php8.1-fpm
systemctl enable zabbix-server zabbix-agent nginx php8.1-fpm
After successfully restarting the services, go to http://10.19.2.1/setup.php to perform the initial configuration. Follow the on-screen instructions to complete the setup.
