![]() Using this option will help restrict the volume of log entries that you need to examine when checking for errors. ![]() The -since today flag will limit the output of the command to log entries beginning at 00:00:00 of the current day only. sudo journalctl -u rvice -since today -no-pager.On CentOS, Fedora, and RedHat-derived systems, use this command to inspect the logs: On Ubuntu and Debian-derived systems, run the following command: If your systemctl output does not include specifics about an AH00526 syntax error, you can proceed with using the journalctl command to examine systemd logs for Apache. The following section explains how to use journalctl to troubleshoot an AH00526 error. If your output does not give specific information about the error location in Apache’s configuration files, you will need to examine journalctl output from the systemd logs. Instead, you can go directly to the file to inspect and edit the erroneous line to resolve the error. If your output indicates a specific line in your configuration file is generating the syntax error, you can skip the journalctl and apachectl configtest troubleshooting steps. The systemctl output in this example also includes some lines from the systemd journal. The correct directive should be SSLCertificateFile, so editing the file to fix the directive name in this example would resolve the error and allow Apache to start. The error is caused by an extra S character at the beginning of the SSSLCertificateFile line in the /etc/apache2/sites-enabled/nf file. In this case, Apache is not running because of the syntax error. Jul 15 13:45:49 f17f01056c5b systemd: Failed to start The Apache HTTP Server.

Troubleshooting with systemctlįollowing the troubleshooting steps from the How to Troubleshoot Common Apache Errors tutorial at the beginning of this series, the first step when you are troubleshooting an AH00526 error is to check Apache’s status with systemctl. Otherwise, the next section will explain how to use systemctl to troubleshoot the error. If you have detected the error using apachectl then skip to the Troubleshooting Using the Built in apachectl Command section of this tutorial. In the latter two cases, Apache will be unable to run because of the error. It can also be found using the systemctl and journalctl commands. The error can be detected using apachectl configtest before an invalid configuration is loaded. It is a generic error that can be indicative of a number of underlying problems. An Apache AH00526: Syntax error message occurs when there is a typo or misconfigured setting somewhere in your Apache configuration files.
