Apache HTTP Server v2.0 is not IBM HTTP Server (powered by Apache).

Apache HTTP Server is not supported on IBM i.

When you install the web server plug-ins the plug-ins installation wizard configures the Web server.

The plug-in was tested with the threaded worker multi-processing module (MPM) on all platforms except Windows. The plug-in was tested with the default threaded MPM on Windows. The plug-in works with the Apache 2 prefork MPM but works best with the worker MPM. The plug-in maintains connection pools to backend WASs and uses in-memory caching. These plug-in functions perform most efficiently when Apache 2.0 is configured to use a single child process with...

ThreadsPerChild = MaxClients

The plug-in can be used with the prefork MPM or the worker MPM configured with multiple child processes, but at reduced efficiency.

The plug-in works with versions of the Apache HTTP Server that claim full binary compatibility with Apache 2.0.47 and later, which are built with compilers and compiler options that are compatible with those used to build the plug-in.

On the Solaris SPARC 64-bit platform, the Plug-ins installation wizard installs both 32-bit and 64-bit versions of the plug-in for Apache 2.0, however it configures the Web server to use the 32-bit plug-in only. If the Web server is 64-bit, in httpd.conf use...

Next steps

The Plug-ins installation wizard installs the GSKIT SSL encryption library at the required level if it is not installed. If we manually copy the plug-in to a new machine, we might not have the required GSKIT libraries for encrypting back-end connections.

After configuring a Web server, we can install applications on it.
