We have an existing dedicated server running LAMP (Ubuntu 14.04.3 LTS & Webmin/Virtualmin) which serves CMS/PHP websites, client portals, email and mysql etc. We have 1 spare dedicated serve which is the same hardware and has Ubuntu 16.04.1 installed but is currently blank and unused. We're looking for a solution so that when Server 1 (the dedicated server already in use) needs maintenance, updates or if it fails then the second spare server detects this and takes over and serves the websites and other services. When Server 1 is then back online, Server 2 would then detect its presence again and sync any updates, file changes/emails or websites changes back to Server 1 again and then switch back so that Server 1 is serving the content again. We only have these two server available for this and no other hardware. The other problem is that we don't think we can use block level mirroring/DRDB or similar due to not having the right partitions setup already on the server in use. We're open to ideas and solutions on this but just need a simple and cheap solution that is reliable and won't corrupt or lose any data. We've already found a couple of potential guides to Heartbeat, corosync, pacemaker and keepalived but are unsure how to best use them and set them up without causing too much downtime on the active Server 1. This guide also mentions using rsync and looks reasonable and fairly simple but misses a couple of the requirements needed and also we're unsure if it is the best solution being a 6 year old post: [login to view URL] We'd also need details of what is implemented and how to make sure it can be recreated in future if we add further servers or if we have a problem and need to reconfigure things. Thanks for any options on this.

Hello, First thanks for the complete specification you wrote, having such, will help us to define best solution that meets the requirements. I am an expirienced system engineer, and familiar with the LAMP stack, to be precise, my current occupation is integration and deployment. Kindly check my profile and recommendation (you can also check my linkedin profile). I manage several dev, integration and production system. Production system are deployed in HA, I use several techniques to implement it depending on customer budget, practices, and existing tool. It goes from proprietary sollution, with special hardware requirement for block level mirroning and failover/LB devices like big IP, to pure free software, that have proven their reliability like heartbeat and co. You mentioned above that you're missing the right partions for blm/drdb, but depending on your hosting company you can add a secondary disk, and partition it the way you need. As per my understanding you want to implement an active passive cluster, with two ways sync, with auto failover, and failback. In order to implement that system, I need to fully understand the current setup (eg : I can't find info on DB hosting, exausitve lis of service to mirror ..) I look farward to implement this HA environment, and discuss some other details,

Hello, I have an experience of over 3 years working on one of the biggest datacenters in my country as a system administrator. I would be glad to help you create the necessary configuration. My suggestion is to create a load balancer solution using rsync and nginx or haproxy. That way there will be high availability for your application. For the MySQL database suggest creating a mysql master to master replication. You can always contact me via chat asking me any questions that you have. Have a nice day!

I suggest to use LHA (Linux High Av) approach. This approach assume that you can control domain pointers (DNS a record) cause I think server don't share same IP subnets. You can use rsync to sync all hosted files and - eventually - sqlclone to create a hot copy of your db data (if you have one)
