Certificate Management Service:Error Restarting Apache After SSL Certificate Installation

Troubleshoot the AH00526 syntax error

Problem

When you install an SSL certificate and restart the Apache server, you may encounter the following error: "AH00526: Syntax error on line xx of /www/server/apache/conf/extra/httpd-ssl.conf".

Cause

This error occurs because the socache_shmcb_module is not loaded. This module manages the session cache and is essential for SSL configurations. The Apache service fails to restart if the module is commented out in httpd.conf but required by httpd-ssl.conf.

Solution

1. Enable the module.

   • Open the httpd.conf configuration file.

   • Find the following line: LoadModule socache_shmcb_module modules/mod_socache_shmcb.so

   • Remove the leading # character from the line to uncomment it.

   • Save and close the file.

2. Verify the configuration.

   • Run the apachectl configtest or httpd -t command to check for configuration syntax errors.

   • If the test is successful, restart the Apache service.

3. Restart Apache.

   • Run systemctl restart httpd or service httpd restart.

   • Verify that Apache starts successfully and that the SSL certificate configuration is active.
