ZooKeeper A.3. Installing and Configuring the Apache HTTP Server The Apache HTTP Server must be installed and configured on all nodes in the assigned failover domain, if used, or in the cluster. The basic server configuration must be the same on all nodes on which it runs for the service to fail over correctly. The following example shows a basic Apache HTTP Server installation that includes no third-party modules or performance tuning. On all node in the cluster (or nodes in the failover domain, if used), install the httpd RPM package. For example: rpm -Uvh httpd-<version>. To configure the Apache HTTP Server as a cluster service, perform the following tasks: Edit the /etc/httpd/conf/httpd.conf configuration file and customize the file according to your configuration. Before the service is added to the cluster configuration, ensure that the Apache HTTP Server directories are not mounted. Add the init script for the Apache HTTP Server service.

Sqoop apxs - APache eXtenSion tool Available Languages: en | ko | tr apxs is a tool for building and installing extension modules for the Apache HyperText Transfer Protocol (HTTP) server. This is achieved by building a dynamic shared object (DSO) from one or more source or object which then can be loaded into the Apache server under runtime via the LoadModule directive from mod_so. So to use this extension mechanism your platform has to support the DSO feature and your Apache httpd binary has to be built with the mod_so module. The module mod_so should be part of the displayed list. The arguments can be any C source file (.c), a object file (.o) or even a library archive (.a). For more details about DSO support in Apache read the documentation of mod_so or perhaps even read the src/modules/standard/mod_so.c source file.
