Install LAMP phpMyAdmin and MariaDB into CentOS7

DustinB3403

Stalled... it appears CentOS has some restrictions in place that don't allow the website to get updated.

So investigating this issue now..

@DustinB3403 At least that error tells you how to go fix things.

Kind of, I've set the permissions on the file in question, and no dice.

Remember if you have SELinux turned on you're going to need to change the type for all of those files.

selinux is on by default.

What do you mean "change the type for all of those files" ?

Either file permissions in the rest of the phpmyadmin folder, of selinux permissions problems. My first guess is normally selinux in these cases.

semanage fcontext -a -t httpd_sys_rw_content_t '/path/to/phpmyadmin(/.*)?'

You have to change the SELinux context type for the files in apache directory. By default the context should be httpd_sys_rw_content_t.

If you do an ls -lZ on the directory all of the files are in it will show you the context type.

I ran this, and was able to get past the above error.

chcon -R -t httpd_sys_rw_content_t /var/www/html/

stacksofplates

you can also do a chcon -R --reference=/var/www/html <directory you need to change> but remember if you just use chcon it can be reversed with restorecon to the bad types. I usually use this as a quick test to make sure it works. Then I'll use semanage to permanently change the context.

JaredBusch

Just turn of SELinux and make sure it all works before you change contexts.

setenforce 0

then if it all works, change contexts and turn it back on and test.

scottalanmiller

I'm with Jared, turning SELinux off during testing and installation is fine. Just make sure it is there before you start using the box.

And that is why I always say to use setenforce 0, because it will not survive a reboot in case you forget.

I got out of the habit of doing this because if the installer changes something in a diff directory that you didn't expect it can be a pain to troubleshoot. I've had that happen a couple times. But in this scenario it's all http files so I agree.

Same here.

DustinB3403

So I've used

sentenforce 0

But now I'm getting stopped here

scottalanmiller

You put in the directory name, rather than the log file name.

DustinB3403

Ah. maybe that is it (it auto fills).

One second, testing

DustinB3403

So I touched a messages.log file into /var/log/syslog and gave it 666 access.

Still no love.

DustinB3403

Same with "messages"

No love.

What OS is that? I thought you wanted the logs from XenServer. That's an Ubuntu log.

/var/log/messages
