Backup

MySQL / MariaDB Databases

mysqldump -uroot -pnagiosxi --add-drop-database nagios > /tmp/nagios_export.sql

 

nagiosql database (Core Configuration Manager)

mysqldump -uroot -pnagiosxi --add-drop-database nagiosql > /tmp/nagiosql_export.sql

 

nagiosxi database (XI program and user preferences)

Note: This is only applicable for fresh installs of XI 5.x onwards. If you upgraded to XI 5.x from a previous version please refer to the PostgreSQL steps below.

mysqldump -uroot -pnagiosxi --add-drop-database nagiosxi > /tmp/nagiosxi_export.sql

 

PostgreSQL Database

Note: This is only applicable for versions of XI before 5.x OR if you upgraded to XI 5.x from a previous version. Fresh installs of XI 5.x onwards do not use PostgreSQL

pg_dump -c -U nagiosxi nagiosxi > /tmp/nagiosxi_export.sql

 

 

Restore

MySQL / MariaDB Databases

nagios database (ndo2db)

mysql -uroot -pnagiosxi nagios < /tmp/nagios_export.sql

mysql -uroot -pnagiosxi nagiosql < /tmp/nagiosql_export.sql

 

nagiosxi database (XI program and user preferences)

Note: This is only applicable for fresh installs of XI 5.x onwards. If you upgraded to XI 5.x from a previous version please refer to the PostgreSQL steps below.

mysql -uroot -pnagiosxi nagiosxi < /tmp/nagiosxi_export.sql

This command will generate a lot of output.

 

 

Emergency Restore

In certain circumstances you have have a corrupt database and do not have a complete backup using our standard backup procedure. Fortunately the databases themselves are backed up regularly and these can be used to perform the restore. These backups are stored in the /store/backups/ directory.

cd /tmp
cp /store/backups/mysql/daily/nagios/nagios_2016-03-27_07h00m.Sunday.sql.gz /tmp/
gunzip nagios_2016-03-27_07h00m.Sunday.sql.gz
