Hi, I would also recommend using a load balancing with Cloudstack if you want to run multiple management servers HA proxy is the preferred choice (works very well for us)
Once you have added the second server you need to change the management server ip in the global setting (search for host) and also the management ip in all the cloudstack agents to the new vip , restart cloudstack I would all suggest setting up two haproxy's one primary and the other secondary using keepalived for redundancy of your haproxy servers Regards Glenn Regards, Glenn Wagner glenn.wag...@shapeblue.com www.shapeblue.com 2nd Floor, Oudehuis Centre, 122 Main Rd, Somerset West, Cape Town 7130South Africa @shapeblue -----Original Message----- From: Indra Pramana [mailto:in...@sg.or.id] Sent: Sunday, 03 April 2016 2:49 PM To: users@cloudstack.apache.org Subject: Adding a new CloudStack management server Dear all, We are running CloudStack 4.2.0 and all this while we are running on just one management server. We intend to add another new management server for redundancy. These are parts of the documentation touching on how to add another new management server: http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.8/management-server/#additional-management-servers http://docs.cloudstack.apache.org/en/latest/administration_guide.html?highlight=management%20server%20load#management-server-load-balancing - Can I confirm that for multiple management servers, a load balancing server or device is compulsory? Can multiple management servers still work without load balancing and still achieve HA? - What do people normally use to setup the load balancing for the management servers? Is a server running haproxy sufficient? - Once the second management server and the load balancer has been setup, I believe we would need to change the management IP to the VIP (virtual IP) of the load balancer, what are the things that need to be changed? Any help is greatly appreciated. Looking forward to your reply, thank you. Cheers. -ip-
