13.4. Configuring Apache for Configuration Management (Deprecated)

JBoss ON manages configuration on Apache resources using an Augeas lens. A special version of Augeas is included with the JBoss ON agent which enables Apache configuration management. That Augeas lens must be enabled on the Apache resource for configuration management to work.

13.4.1. Considerations and Notes for Apache Configuration Management

Deprecated Augeas Plug-in

Apache configuration management is supported through a special Augeas agent plug-in, which connects with and manages the Augeas lens on the Linux instance. The Augeas agent plug-in is deprecated in JBoss ON 3.1.1 and may be removed in a later release.

Augeas and Apache Monitoring

The Augeas lens is not required for Apache monitoring. It is only used for Apache configuration management. An Apache resource can be monitored, with alerting, operations, and all other management tasks available without any additional configuration. The Augeas lens is used only for editing the Apache configuration files and virtual hosts through JBoss ON.

Supported Platforms for Apache Configuration

Apache configuration management is only supported for Apache instances installed on Linux.

Disabling noexec Options for Apache Directories

If the /tmp directory is configured a noexec in the fstab file, the agent throws exceptions because it cannot properly initialize the Augeas lens. In that case, the Configuration tab is unavailable for the Apache resource.

Make sure that the /tmp directory does not have noexec set as an option. 
#
# /etc/fstab
#
tmpfs /dev/shm tmpfs defaults 0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0

13.4.2. Enabling Configuration Management

Apache configuration management is configured as one of the connection settings for the Apache resource, which sets how the agent connects to the resource.
  1. Click the Inventory tab in the top menu.
  2. Select the resource type in the Resources menu table on the left, and then search for the Apache resource.
  3. Click the IP address of the Apache instance.
  4. Open the Inventory tab, then click the Connections subtab.
  5. Jump to the Augeas Configuration section.
  6. Select the Yes radio button to enable the Augeas lens.
