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”*
Would be great if you could contribute/correct the docs at:
http://docs.cloudstack.apache.org
You can fork on github and submit a pull request.
thanks

I've followed the below link and edited the /etc/cloudstack/management/db.properties file, http://docs.cloudstack.apache.org/projects/cloudstack-administration/en/4.4/reliability.html db.ha.enabled=true db.cloud.slaves=10.0.0.12 db.usage.slaves=10.0.0.12 But, I'm getting HTTP Status 404 error. Can anyone explain the step by step process to make slave as mater and master as slave in CloudStack point of view? I'm using ACS4.4.0. Thank you, Suneel Mallela
