Httpd Failed
Aug 12, 2008I have httpd down right now without any error outputted on errors_log
my server is with 4 Quad-Core Intel Xeon 2.66GHz (16 CPu) and 16GB of RAM. Is running CentOS Linux 5.1 and Apache/2.2.8. The site that will be running in this server has an average of 360,000 pageviews daily, so we want to make sure to tweak the configuration at its best.
my httpd.Conf:
Include "/usr/local/apache/conf/includes/pre_main_global.conf"
Include "/usr/local/apache/conf/includes/pre_main_2.conf"
# # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # #
# Direct modifications to the Apache configuration file may be lost upon subsequent regeneration of the #
# configuration file. To have modifications retained, all modifications must be checked into the #
# configuration system by running: #
# /usr/local/cpanel/bin/apache_conf_distiller --update #
# To see if your changes will be conserved, regenerate the Apache configuration file by running: #
# /usr/local/cpanel/bin/build_apache_conf #
# and check the configuration file for your alterations. If your changes have been ignored, then they will #
# need to be added directly to their respective template files. #
# #
# It is also possible to add custom directives to the various "Include" files loaded by this httpd.conf #
# For detailed instructions on using Include files and the apache_conf_distiller with the new configuration #
# system refer to the documentation at: [url] #
# #
# This configuration file was built from the following templates: #
# /var/cpanel/templates/apache2/main.default #
# /var/cpanel/templates/apache2/main.local #
# /var/cpanel/templates/apache2/vhost.default #
# /var/cpanel/templates/apache2/vhost.local #
# /var/cpanel/templates/apache2/ssl_vhost.default #
# /var/cpanel/templates/apache2/ssl_vhost.local #
# #
# Templates with the '.local' extension will be preferred over templates with the '.default' extension. #
# The only template updated by the apache_conf_distiller is main.default. #
