4 Configuring Phabricator to use multiple web servers.
9 You can run Phabricator on multiple web servers. The advantages of doing this
12 - you can completely survive the loss of multiple web hosts; and
13 - performance and capacity may improve.
15 This configuration is simple, but you must configure repositories first. For
16 details, see @{article:Cluster: Repositories}.
22 After configuring repositories in cluster mode, you can add more web hosts
25 First, deploy the Phabricator software and configuration to a host, then
26 register the host as a cluster device if it is not already registered (for
27 help, see @{article:Cluster: Devices}.)
29 Once the host is registered, start the web server, and then add the host to the
32 Phabricator web servers are stateless, so you can pull them in and out of
35 You may also want to run SSH services on these hosts, since the service is very
36 similar to HTTP, also stateless, and it may be simpler to load balance the
37 services together. For details, see @{article:Cluster: SSH Servers}.
