Subject Re: CloudStack DataBase HA Restoration Test
Date Tue, 14 Oct 2014 09:36:26 GMT
Hi All,

I got the solution for cloudstack database high availability.

Follow the steps to enable the database high availability in cloudstack.

1)       Go to the path:

*“/usr/share/cloudstack-management/webapps/client/WEB-INF/lib/”*

Find the *“cloud-plugin-database-mysqlha-4.3.1.jar”  *file.

2)       Create the path:

*“/usr/share/cloudstack-mysql-ha/lib/”*

Copy the above file to this path.

3)       Edit the file *“/etc/cloudstack/management/catalina.properties” *

check the *“common.loader” *line looks like:

*“common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar,/usr/share/java/mysql-connector-java.jar,/usr/share/cloudstack-mysql-ha/lib/*.jar”*

4)       Edit the file *“/etc/cloudstack/management/db.properties”*

*db.ha.enabled=true*

*db.cloud.slaves=<slave IP address>*

*db.usage.slaves=<slave IP address>*

5)       Restart the management server.

*“Service cloudstack-management restart”*



*Regards,*

*Rajasekhar.*
