Enable mod_expire apache module

mod_expire controls the setting of the Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses. These HTTP headers are an instruction to the client about the document's validity and persistence. If cached, the document may be fetched from the cache rather than from the source until this time has passed. After that, the cache copy is considered "expired" and invalid, and a new copy must be obtained from the source.

Following are the steps to enable  mod_expire in the server.

* Open the file /etc/httpd/conf/httpd.conf and check if the following line present in it.



LoadModule expire_module modules/mod_expire.so

If not, add it.

* Then  create a new file /etc/httpd/conf.d/expire.conf with the lines:

 <IfModule mod_expires.c>
 ExpiresActive On
 ExpiresByType image/jpg "access plus 60 days"
 ExpiresByType image/png "access plus 60 days"
 ExpiresByType image/gif "access plus 60 days"
 ExpiresByType image/jpeg "access plus 60 days"
 ExpiresByType text/css "access plus 1 days"
 ExpiresByType image/x-icon "access plus 1 month"
 ExpiresByType application/pdf "access plus 1 month"
 ExpiresByType audio/x-wav "access plus 1 month"
 ExpiresByType audio/mpeg "access plus 1 month"
 ExpiresByType video/mpeg "access plus 1 month"
 ExpiresByType video/mp4 "access plus 1 month"
 ExpiresByType video/quicktime "access plus 1 month"
 ExpiresByType video/x-ms-wmv "access plus 1 month"
 ExpiresByType application/x-shockwave-flash "access 1 month"
 ExpiresByType text/javascript "access plus 1 week"
 ExpiresByType application/x-javascript "access plus 1 week"
 ExpiresByType application/javascript "access plus 1 week"
</IfModule>

* Restart apache service.

edquota: Quota write failed (id 526): Invalid argument

Cannot start mysql

Problem:
[~]# /etc/init.d/mysql status
ERROR! MySQL is not running, but lock exists

 [~]# /etc/init.d/mysql start
 Starting MySQL. ERROR! The server quit without updating PID file (/var/lib/mysql/*)

Solution:

 [~]# ps aufx | grep mysql
 If it shows the mysql process, Kill that mysql process using
[~]#killall mysql

  [~]# rm -f /var/lock/subsys/mysql

 [~]# /etc/init.d/mysql start

 If still it doesnt  solve the issue,
 it may be that MySQL is not starting because it is unable to load a variable set in /etc/my.cnf.
If there are a lot of entries in your my.conf, it may be easier to mv /etc/my.cnf to something like /etc/my.cnf.old and then see if MySQL starts.

Also, check the mysql log file and see what it says. A few examples:

1.Error:

MySQL installation Error - InnoDB: Error: pthread_create returned 11 

Apply this fix :

  [~]#ulimit -s unlimited

Then start mysql again.
2.Error:

Plugin ‘InnoDB’ registration as a STORAGE ENGINE failed. 

 

Apply this fix :


Go to the data directory and remove log files look like ib_logfile0, ib_logfile1 and ib_logfile2.  Then start mysql.

3.Error:
 ERROR! MySQL manager or server PID file could not be found!

Apply this fix :

Go to  /etc/my.cnf file
 Put the below in your my.cnf then try again.

skip-innodb

  This will skip the InnoDB engine on startup. If the problem is related to InnoDB, MySQL will start without InnoDB support.

Apache – “Client denied by server configuration”

Problem: You will get a 403 in your web-browser while access your site.

The error log (/usr/local/apache/logs/error_log or /etc/httpd/logs/error_log) will shows like this:
“client denied by server configuration: /path/to/files”

Then you probably have denied access to the directory in the httpd.conf file.

Allow access by adding:
<directory /path/to/files>
allow from all
</directory>

If your are using VirtualHosts then add the directory-block inside the <virtualhost> block.
