2.2. Web Server Configuration
2.2. Web Server Configuration The following procedure configures an Apache HTTP server. Ensure that the Apache HTTP server is installed on each node in the cluster. You also need the wget tool installed on the cluster to be able to check the status of the Apache HTTP server. On each node, execute the following command. In order for the Apache resource agent to get the status of the Apache HTTP server, ensure that the following text is present in the /etc/httpd/conf/httpd.conf file on each node in the cluster, and ensure that it has not been commented out. If this text is not already present, add the text to the end of the file. When you use the apache resource agent to manage Apache, it does not use systemd . Because of this, you must edit the logrotate script supplied with Apache so that it does not use systemctl to reload Apache. Remove the following line in the /etc/logrotate.d/httpd file on each node in the cluster. Replace the line you removed with the following three lines. Create a web page for Apache to serve up. On one node in the cluster, mount the file system you created in Section 2.1, "Configuring an LVM Volume with an ext4 File System" , create the file index.html on that file system, then unmount the file system.
