Certificate Management Service:What do I do if an error is reported when I restart the Apache service after I install an SSL certificate on an Apache server?

What do I do if the AH00526 error is reported when I restart the Apache service after I install an SSL certificate on an Apache server?

Problem description

When you restart the Apache service after you install an SSL certificate on an Apache server, the "AH00526: Syntax error on line xx of /www/server/apache/conf/extra/httpd-ssl.conf" error message appears.

Possible cause

In most cases, the error message appears because the socache_shmcb_module module s not correctly loaded for the httpd-ssl.conf file. The socache_shmcb_module module is used for session caching and is essential for SSL configuration. If the socache_shmcb_module module is commented in the httpd.conf file and the httpd-ssl.conf file depends on the httpd.conf file, the Apache server fails to be restarted.

Solution

1. Remove the comments:

   • Open the httpd.conf file.

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

   • Delete the comment delimiter (#) in front of the line.

   • Save and close the file.

2. Verify the configuration:

   • Run the apachectl configtest or httpd -t command to check the syntax of the configuration file.

   • If no error message appears, restart the Apache service.

3. Restart the Apache service:

   • Run the systemctl restart httpd or service httpd restart command to restart the service. Choose a command based on your system.

   • Check whether the Apache service is successfully restarted and whether the SSL configuration takes effect.

If the issue persists, contact your account manager.
