Migrate the extension

This chapter explains you how to move your reporting server to another one. It can be usefull if you want to migrate your reporting server from CentOS 6 to CentOS 7.

Migration of the interface extension is linked to Centreon central migration.

Install the new reporting server​

Install your new reporting server based and the Centreon MBI repositories using the standard documentation.

Synchronizing files & data​

Stop mysqld on both Reporting servers

service mysql stop

Copy data from the old reporting server to the new one:

rsync -avz /var/lib/mysql/* root@IP_New_Reporting_Server:/var/lib/mysql/

Execute the following command to ensure database files compatibility:

mysql_upgrade
  • If no error is visible, restart MariaDB and continue to the section "Move generated reports"

  • If you see errors, especially on the following tables mysql innodb_index_stats, innodb_table_stats, gtid_slave_pos, it might be caused by an incompatibility between MySQL/MariaDB 5.5 and MariaDB 10.1. In that case, follow the procedure below:

    service mysql stop
    cp -a /var/lib/mysql/ /var/lib/mysql.bak
    cd /var/lib/mysql/mysql/
    rm innodb_index_stats.frm innodb_index_stats.ibd innodb_table_stats.frm innodb_table_stats.ibd gtid_slave_pos.frm gtid_slave_pos.ibd
    service mysql start

    Then manually recreate the tables:

    mysql mysql < repair_mysql_upgrade.sql

    Download the file here: repair_mysql_upgrade.sql

Be sure to copy the the custom report & ressources you designed to your new reporting server in the same folders.

Move generated reports​

In case you also move you Centreon central server, you need to synchronize the folders containing generated reports on your new Centreon server to be able to have them on the interface:

rsync -avz /var/lib/centreon/centreon-bi-server/archives/ root@IP_New_Centreon_Server:/var/lib/centreon/centreon-bi-server/archives/
