You cannot restart the web server:
Service /etc/init.d/httpd failed to start
Generating the web server configuration fails with the following error:
Unable to generate the web server configuration file on the host <server1.plesk-server.info> because of the following errors: Template_Exception: Can not restart web server: Service /etc/init.d/httpd failed to start Service /etc/init.d/httpd failed to start file: /usr/local/psa/admin/plib/Service/Driver/Web/Server/Apache.php line: 100 code: 0 Please resolve the errors in web server configuration templates and generate the file again.
The Apache error log
'/var/log/httpd/error_log' reveals the following error:
(2)No such file or directory: httpd: could not open error log file /var/log/apache2/bara-bara-serv.com_error.log
The Apache configuration contains a reference to a non-existent file or directory.
Create the required file (directory) and start the httpd service:
mkdir /var/log/apache2/ touch /var/log/apache2/server.com_error.log /etc/init.d/httpd restart
When the web service is started, try to find out which configuration file contains a link to the mentioned log file. You can do this by going through the configuration inside the
'/etc/httpd/conf.d/' directory. Each config may contain the
'Include' directive, which in turn includes the next file.
Parallels Plesk manages configs that are listed in
'/etc/httpd/conf.d/zz010_psa_httpd.conf'. If the file mentioned in the error is not present in the files included there, it was probably configured manually.
It is not recommended that you use a custom configuration in Apache on a server managed by Plesk, so it is strongly recommended that you remove any custom entries.
