cannot see database cPanel for domain

While accessing Phpmyadmin via Cpanel , under databases it shows ” No Database ” . But you can see the databases while accessing through WHM.

This can be due to many reasons . One of the reason I found is because the user doesn’t have SHOW DATABASES privilege .

From the server my.cnf remove the line

skip-show-database

Restart Mysql

Try to access Phpmyadmin .

–skip-show-database

With this option, the SHOW DATABASES statement is allowed only to users who have the SHOW DATABASES privilege, and the statement displays all database names. Without this option, SHOW DATABASES is allowed to all users, but displays each database name only if the user has the SHOW DATABASES privilege or some privilege for the database. Note that any global privilege is considered a privilege for the database.

Apache status in WHM shows error

http://forums.cpanel.net/f5/apache-status-not-working-after-customizing-port-144581.html

. Why is my mysql database in cpanel showing no disk space usage.

http://www.thecpaneladmin.com/disk-space-for-mysql-databases-in-cpanel-show-as-0mb/

import a MySQL dumpfile into my database

How do I import a MySQL dumpfile into my database?

Applies to: Grid System

After you have dumped out your data into a file as described here, FTP or scp that dump file to the home directory (/) on our system.

Once you have uploaded the dump file to your account here, get a shell prompt on our system using telnet or ssh.

Now import the dump file into MySQL by typing all the following on 1 single line at the shell prompt:

mysql -p -h DBSERVER dbname < dbname.sql

The above assumes that your database name on our system is "dbname" and the dumpfile that you uploaded was named "dbname.sql". Replace those with your correct database name and dumpfile filename. Also replace DBSERVER with your correct database server name.

If you have followed this other FAQ on how to create a .my.cnf preference file, you would not have to type so much when connecting to the MySQL Monitor from the shell prompt. With a proper .my.cnf file you could have imported the dump by just typing this at the shell prompt:

mysql < dbname.sql

create a database via phpmyadmin.

first set a password for sql frm front end.
den phpadmin wil bcom visible.
then try onscreen procedure for creating databsae in phpmyadmin

sending mails wid an error

check all account settings in whm /cpanel.
There wil b some advancd settings(not sure).check it.
der wil b a destination inside dat.check it.

create a user
# useradd ftpuser

give passwd protection

create any file under that user for eg: abc.com

To check if ftp is listening

open a new terminal and check

# telnet ip 21

to open ftp connection type
# ftp ip

then to transfer files btw ur local s/m and the remote user use put filename
n get filename commands..

You can put file to the ftpuser's home from your local system home directory and viceversa..

Enabling Cgi Script

Change <Directory /usr/local/apache/cgi-bin> to

your home directory for eg:
<Directory /home/user/public_html/cgi-bin>
then give AllowOverride All
               Options +ExecCGI

</Directory>

AddHandler cgi-script .cgi .pl

ScriptAlias /cgi-bin/ "/home/user/public_html/cgi-bin/"

Done with the conf file..

Then in ur public_html folder create cgi-bin folder. Inside it create index.pl file.

                  #!/usr/bin/perl -w
    print "Content-type: text/html\n\n";
                  print "Hello, world";

complie the perl script using command -   perl -wc index.pl
