Installing phpMyAdmin in my Cent OS 5.3
I did this by yum, which i think is the easiest way.
[root@localhost ~]# yum install phpmyadmin
This will install it in /usr/share/phpmyadmin
Now, configure it by editing config.inc.php
[root@localhost html]# gedit /usr/share/phpmyadmin/config.inc.php
add the blowfish secret,
$cfg['blowfish_secret'] = 'a8b7dafdferHJHJ^&U^45776TIUuiYc6d';
and i also changed to mysqli in,
$cfg['Servers'][$i]['extension'] = 'mysqli';
Now you could access the phpMyAdmin by,
http://127.0.0.1/phpmyadmin/
This is possible because an alias is created for apache to the directory where phpMyAdmin in installed [ie /usr/share/phpmyadmin]. This is done in the file,
[tony@localhost ~]$ gedit /etc/httpd/conf.d/phpmyadmin.conf
You will see a lines like,
Alias /phpmyadmin /usr/share/phpmyadmin
Alias /phpMyAdmin /usr/share/phpmyadmin
Alias /mysqladmin /usr/share/phpmyadmin
————-
You could also install phpMyAdmin manually by downloading phpMyAdmin.
Make sure you download the version 2.xx and not 3.xx[requires PHP 5.2] as Cent OS 5.3 has only PHP 5.1 by default
Extract the tar.gz file to your desktop.
Copy it to /var/www/html/phpmyadmin as root,
[root@localhost ~]# mv /home/tony/Desktop/phpMyAdmin-3.2.1-all-languages /var/www/html/phpmyadmin
Give the appropriate permission for apache,
Set owner as apache
[root@localhost html]# chown apache -R /var/www/html/phpmyadmin/
Set the group owner as your user, this is good as you can edit the files easily,
[root@localhost html]# chgrp tony -R /var/www/html/phpmyadmin/
Now give group user the write permission
[root@localhost html]# chmod g+w -R /var/www/html/phpmyadmin/
Now, add the blowfish secret and mysqli extension as above,
Thats all.

Excellent…Now I find the config file. Thanks a lot it was pretty helpful.
Thank you for the guideline Tony. I installed phpmyadmin 3.2.5 using the steps above. Now, I am getting a blank page when I goto http://localhost/phpMyAdmin
No source code for the page. Your input is appreciated.
Hi Sadesh,
PhpMyAdmin 3.2+ requires PHP 5.2 which is not available in CentOS 5.3 by default. This might be the reason. Try using phpmyadmin 2.11 . I have noted this in the post. [although i now see that in the code it is written wrongly].
If you have PHP5.2 or later, Check if the files are present.
Any difference if you try http://127.0.0.1/phpmyadmin/ ?

Thank you admin for the fast reply. I have PHP 5.3.1 installed. The files of phpmyadmin are in /usr/share/ and i have also created the alias. Restarted httpd.
I also tried 127.0.0.1/phpmyadmin…it is still a blank page
but, the website is working fine, which is because of working php and mysql.
Also, when i tried to do a database backup using webmin, get this following error;
Database backup failed : mysqldump failed :
mysqldump: Couldn’t execute ‘SHOW FUNCTION STATUS WHERE Db = ‘irhfr”: Column count of mysql.proc is wrong. Expected 20, found 16. Created with MySQL 50077, now running 50142. Please use mysql_upgrade to fix this error. (1558)
Scheduled backup for database left disabled.
FYI, my university has automated backup of the server and the databases using also mysqldump. Are these related?
Hey Sadesh,
Looks like you might be having some syntax errors in your conf file. And because of that the php execution is going into a fatal error and not displaying anything at all.. why don’t you try checking the syntax of your conf files using php -l
for eg. php -l /usr/share/phpmyadmin/config.inc.php
The ideal way to tackle this would be to do a tail -f on the apache error logs and see what errors are getting printed, and then you’ll have a better idea. Do let us know if this helped.

Thank you Sonic for the reply. This is what I got after execution of the php -l command;
*** No syntax errors detected in /usr/share/phpmyadmin/config.inc.php ****
Regarding “The ideal way to tackle this would be to do a tail -f on the apache error logs and see what errors are getting printed, and then you’ll have a better idea.”
How do I do this? thanks again.

Hi Sadesh,
You have to find your apache error log files, in Cent OS and similar distros its in
/var/log/httpd/error_log
Next, giving
tail -f anyfilenamewill print out the latest entries in that text file real time.In short, you do a
tail -f yourapacheerrorlogin a shell, and then try to access the phpmyadmin in browser, to see what errors are getting printed.Btw, why dont you also try to do a manual installation of phpMyAdmin (as said in the second part of the article) and see if it works.
Thank you very much tony. I have no idea what I did except,
mysqlcheck –check-upgrade –all-databases –auto-repair
mysql_fix_privilege_tables
shell> mysql_upgrade
Now, my phpmyadmin and webmin mysql db backup are working just fine. Again, I see following errors in the log, when I did as u instructed me.

Thanks a lot.
Good that you got it working.
Regarding the error message: A quick google search shows that PHP 5.3 no longer supports those functions. Your phpMyAdmin seems not fully compatible with 5.3 yet.
Anyway, since things are working better don’t bother about it..
tony
Cool…Thanks a lot for ur active and quick response.
