CentOS 8.x Cloudstack 4.15 Setup Mariadb server

Home > CentOS > CentOS 8.x > Virtualization > Cloudstack 4.15 > Setup Mariadb server

The below steps assume Mariadb server is different then cloudstack management server. If you want to setup mariadb and management on same machine, there might be package conflict as cloudstack-management package might try to use mysql instead of mariadb. In that case use mysql instead of mariadb to get successful setup

To setup Mariadb server for using with Cloudstack 4.15 use following steps:

1. Initialize server using CentOS 8.x Cloudstack 4.15 Initialize infrastructure server (except optional java 11 installation)
2. Install mariadb server:

   dnf -y install mariadb-server

3. Edit '/etc/my.cnf.d/mariadb-server.cnf' and under '[mysqld]' section paste:

   innodb_rollback_on_timeout=1
   innodb_lock_wait_timeout=600
   max_connections=350
   log-bin=mysql-bin
   binlog-format = 'ROW'

4. Start and enable database using:

   systemctl start mariadb
   systemctl enable mariadb

5. Run mysql_secure_installation and set root password

   mysql_secure_installation

   Ensure that for "Disallow root login remotely" answer is N (No) instead of default yes

6. Give grant permission to root user on all databases from any remote machine:

   # mysql -u root -p
   > grant all privileges on  *.* to 'root'@'%' identified by '<secret-root-password>' WITH GRANT OPTION;
   > flush privileges;

   Better option is to give this privilege only from cloudstack management server instead of using '%' (everywhere)
