well Ive been having this issue in Beta 6.6.0 (beta 2)
I have looked around for a solution to the same problem.
what i have noticed is the following:

yum clean all && yum upgrade

reported no updates

yum install phpmyadmin

reported already installed
after setting up an alias in the httpd.conf file as sugested i natuarly restarted the HTTPD service

[root@demo conf.d]# service httpd restart

Stopping httpd:                                            [  OK  ]

Starting httpd: [Sun Jan 11 16:31:45 2015] [warn] The Alias directive in /etc/httpd/conf/httpd.conf at line 1009 will probably never match because it overlaps an earlier Alias.

                                                           [  OK  ]

now this looked pretty odd since i just added an alias whent to my browser and tried to access the webpage and sure enough

Forbidden



You don't have permission to access /phpmyadmin on this server.

now that to me sounds like a permission problem and as the Alias was ALREADY in place (at the time of install im guessing)
i figured id look around and found a few interesting things in side of this file

/etc/httpd/conf.d/phpMyadmin.conf

seems like by defualt it ONLY allows localhost as stated in the comments section at the top of the file (i'll attach it here if any one would like to see the file)
now i havent yet adjusted any settings yet but when i do and get some results i'll post back and provide the changes

EDIT: forgot the attached file

I had the problem aswell. The code in the picture ALex gave fixed my problem.

I did not have the config in the folder and when i created it and typed the code displayed on the image it suddenly worked.

But now it says that the login is incorrect, altho the login via putty works good....

Any ideas?

thank you, had exactly same problem on 6.3 with a clean install, this solved my problem.

yess..!! now PhpMyAdmin on my server is back... thanks

Yum is telling phpMyAdmin 3.5.2.2-1.el6.noarch is already installed

I think you just solved the other mystery! That 3.5.2.2-1.el6 version is an EPEL build of phpMyAdmin - it doesn't have the little hooks to make it ClearOS-friendly. If you run an upgrade with the EPEL repository enabled, you may end up installing the EPEL version instead of the custom version intended for ClearOS. You can upgrade to the ClearOS version today by running:

# yum --enablerepo=clearos-updates-testing upgrade phpMyAdmin

I just added a tracker item to blacklist the phpMyAdmin package from EPEL.

I got it working now. I restarted httpd instead of webconfig after creating Alexis missing file. Everything works now.

Hi,

I to am having this problem. I have tried restarting webconfig, tried restarting mysqld, did yum clean all && yum upgrade, tried yum install phpMyAdmin, nothing seemed to make a difference. Yum is telling phpMyAdmin 3.5.2.2-1.el6.noarch is already installed. I tried reinstalling phpMyAdmin and then restarting webconfig but still no luck.

I tried Alexis C suggestion, however the phpMyAdmin.conf did not exist, so I created it with the contents from his attached picture. This gave me a certificate error, but when I attempted to continue I got the 404 error again.

Any further suggestions?

Thanks for the feedback. At this point, we'll just push out the "restart webconfig after install" fix. Hopefully, that's all that it was.

it's strange, it works now.
thank you.

Best regards

Just to clarify, does the following command resolve the issue:

service webconfig restart

The reason I'm asking: I can duplicate the issue but then fix it with the above restart command. It sounds like there might be more to it for some installs.

No change...the same...
Installed 6.3 Final version.

Did the restart work?

still Investigating... ?

Can you try the following from the command line?

service webconfig restart

have same problem

developer can remote my server if necessary

regards

Investigating...

Hmmm fresh install 6.3.0 beta...and I have this problem. I have two boxes, both would appear to be configured the same - but one presents this problem and the other doesn't! its late but there is the following log snippet...

/var/log/webconfig/error.log

[Tue Jul 31 23:46:02 2012] [error] [client 192.168.1.5] File does not exist: /usr/clearos/framework/htdocs/mysql, referer: https://192.168.1.100:81/app/mysql

Weird, I don't need that line for it to work here

I had the same problem running COS Enterprise 6.2.0 (trial), unable to access phpMyAdmin.

Followed the post of Alexis C and edited phpMyAdmin adding the indicated lines and was able to access phpMyAdmin, after a reboot, and create the database I required for Concrete5 instalation successfully.

Hello, I think i might help you on this problem.

I had the same issue (404 error when browsing to server/mysql) and after a while I resolved it by doing this :

 vim /usr/clearos/sandbox/etc/httpd/conf.d/phpMyAdmin.conf 

After, you have to add the line "Allow from localhost" on both directories :
http://img837.imageshack.us/img837/8620/mysqlfix.png

After a restart of httpd service (edit : or a reboot) it should work (at least it worked for me).

Same problem here, clean install from "clearos-professional-6.2-x86_64.iso" and "Go To MySQL Management Tool" link gives 404 error. (mysql, web apps installed)

Tried all the suggestions mentioned in this thread, but they did not work.

What did work was this: http://www.linuxquestions.org/questions/linux-software-2/how-to-fix-the-requested-url-phpmyadmin-was-not-found-on-this-server-796610/#post4539480

phpmyadmin quick intstall quide

Latest updates, fresh install. Same result here.

Anyone have the fix?

Yup... I just tried your install and still has the same problem.

Strange! is it installed?

yum install phpMyAdmin --enablerepo=clearos-updates-testing

Hi

It is a fresh install, phpMyadmin was not installed, i installed it and added the database, so now its "working" but database management /mysql link does not work. I have not tested yum clean all && yum upgrade, i installed 6.2 final .iso

Same problem here! phpMyadmin link does not appear to work on the MySQL Database management tab. When I press the link button "Go To MySQL managemnt Tool" it says:

The requested URL /mysql was not found on this server.

Does something else need to be installed?

Odd - works OK here, have you applied the latest updates?

is phpMyAdmin installed? is the mysql service running?

Is this a fresh install from the ISO or an upgrade from beta?

yum clean all && yum upgrade
