Adding an additional memcached servers helps to distribute the cache and balance the load across the memcached servers.
- To add an additional memcached server
- Edit networking.properties on all instances.
- Update the MemCachedServers entry
- Restart all servers, following the Server Restart Sequence
Note: The sequence is important!
- Example
There is one memcached server running on serverA (192.168.0.1) on port 11211. On each instance, the networking.properties has this:
MemCachedServers=192.168.0.1:11211
A second memcached server is brought up on serverB (192.168.0.2) on port 11211. The networking.properties file is edited on all instances so it looks like this:
MemCachedServers=192.168.0.1:11211 192.168.0.2:11211
After following the Server Restart Sequence, all instances are using the new, distributed cache.
If a 3rd memcached server is added (192.168.0.3), the networking.properties file will look like this:
MemCachedServers=192.168.0.1:11211 192.168.0.2:11211 192.168.0.3:11211
Again, the Server Restart Sequence is followed to enable the new configuration.
