Q: Wordpress plugin update/install failure

I've been reading all sorts of information all over the web on this topic. I just installed Wordpress on my Fedora 22 box, x64. The installation went perfectly, I'm able to access the site, but cannot update plugins at all. I've seen two different directions so far: 1) Set up the FTP server tha...

s1lv3r

Yeah, you are already on the right track. You need to find out, under which user your PHP script gets executed, to then set the needed permissions. You can try $processUser = posix_getpwuid(posix_geteuid()); print $processUser['name']; in a PHP script to get the user name.

Aurelius

I'm far from a PHP user. How can I run that?

s1lv3r

Put it into a .php file and then access it via the browser just like you do with your WordPress install. :|

Aurelius

Just tried that, as I remember I did the phpinfo() thing in info.php. However, replacing that with the code you mentioned generated a 500 server error.

s1lv3r

Just put it exactly the way as in that page (scroll down to the first comment): php.net/manual/en/function.get-current-user.php

Aurelius

18:08

Makes no difference what's in the file, I'm getting a 500 server error. This might point to the fact that I couldn't find the php process before.

s1lv3r

Chat is fine. ;)

So your phpinfo is still working?

It also contains the username ... it's under the heading "Environment".

Aurelius

No, the phpinfo is not working

Returns a 500 error, though the wordpress site is still up

s1lv3r

That doesn't really make any sense ...

Aurelius

It really seems as though the php process isn't running, but wouldn't it have to be for the wordpress to work?

s1lv3r

so what does your phpinfo file contain?

Ya, if WordPress runs the PHP process must be alive.

Aurelius

18:16

Right now, it has <?php
$processUser = posix_getpwuid(posix_geteuid());
print $processUser['name'];
?>

but I also had <?php phpinfo(); ?>

s1lv3r

and <?php phpinfo(); ?> also results in 500 now?

Aurelius

Yup

It was working before I installed wordpress

Thank you so much for taking the time to help me

s1lv3r

and if you just put phpinfo(); into the wordpress index.php after the opening <?php ...

Aurelius

I'll try that

lol now the front page has phpinfo in it

I'll try replacing the code with the checkuser code

whoa, getting 500 error

s1lv3r

The information about the user should also be in the phpinfo output somewhere under "Environment", but it should be fine either way.

Aurelius

18:19

Okay, let me check that again

s1lv3r

I think your SELinux maybe doesn't like posix_geteuid().

Aurelius

I'm not getting any SELinux errors, that I can see anyway

what am I looking for in phpinfo?

s1lv3r

In the section "Environment" there is a variable "USER".

Aurelius

Not seeing one. I see admin is root@localhost but that's the only username I can see

this is under the heading Apache Environment, right?

s1lv3r

There should be "Environment" only.

Aurelius

18:23

oh wait, I found the Environment heading way down, still no USER variable

s1lv3r

... did you follow a tutorial to setup the Apache? Do you know which request handler is used?

mod_php or php-fpm maybe?

Aurelius

I followed itzgeek.com/how-tos/linux/fedora-how-tos/…

however, instead of changing to iptables, I just edited my current firewalld settings as I didn't want to rewrite them all for iptables

could that be the issue?

s1lv3r

No, I don't think so.

Aurelius

I am able to access port 80 and the front page, so that's what I thought as wel

s1lv3r

Networking/firewalls shouldn't change anything about file permissions ....

yeah, exactly.

Aurelius

18:26

and the ftp ports are open, I can connect from my laptop, but WP doesn't like those creds.

but that's a whole other issue, I think.

s1lv3r

yeah, the WP ftp handler isn't that great ... but it must work without it.

Aurelius

I would be happy to give you SSH access if you want to poke around, but that's asking a lot. It's all good if you can't figure it out

asking a lot of you I mean

s1lv3r

hmmm ... guess that would be the fastest way. I would be fine to have a quick look. But please change the password - you shouldn't give random strangers on the internet your root-password and the chat protocols are public. ;)

Aurelius

:P okay. I will change my user's password, and forward the port22. Give me five minutes

sorry, every time I want to change my routers settings I have to reboot it

such a pain

s1lv3r

Can you give the link to the phpinfo in the meanwhile, or is it internal only?

Aurelius

18:34

Its internal right now

I will forward port 80 as well, if you want

my IP is 174.119.138.5, just give me two more seconds to get it all set up

s1lv3r

That would be great, ... I could swear the user info must be somewhere in there. ;)

Aurelius

okay, port 22 is open

username mrowsell

password aurel!us

let me know if it lets you in

I'll add port 80 now

s1lv3r

port 22 still blocked :(

Aurelius

argh, stupid router. It didn't save, just a minte

s1lv3r

ok :)

Aurelius

18:42

omfg I hate this router so much. I need to bridge it to my nice D-Link when Ig et the chance

It's one of the combo ones

man, it just keeps resetting the access page after 2 minutes past reboot, and then I can't get back in

s1lv3r

that's annoying. Too bad ...

Aurelius

its okay, just had to switch to ethernet

or not...

Urgh.

thanks for your patience

I'll try once more, and if I can't then I'll have to try something else

s1lv3r

Ok, I'm sure we can make it without SSH. ;)

Aurelius

hopefully. alright, I'm about to toss this router out the window. it just refuses to connect after the first 30 seconds....

s1lv3r

hmmm ... okay. :p

Back to phpinfo ...

Could you just copy & paste the whole content here?

Aurelius

18:50

Sure thing

Its huge

s1lv3r

ya, dunno if chat can handle it.

Aurelius

oh wait, do you have teamviewer?

s1lv3r

or put it into a pastebin.com ...

Aurelius

you could just use that

its already set up on that pc

s1lv3r

Ah okay. Which version?

I got 11.

Aurelius

18:52

same

its number is....

901 909 197

password e9v54z

there we go

s1lv3r

:)

can you show the phpinfo?

Aurelius

yup

oops must have removed it

one sec

there it is

s1lv3r

your username is apache ;-)

Aurelius

but that's what the directories are set to be owned as

s1lv3r

where is the wordpress site?

Aurelius

18:56

it's all under /var/www/html

might need to sudo that

s1lv3r

:)

Aurelius

aurel!us

:)

thanks so much man

s1lv3r

hummm

Aurelius

I think I ran sudo chmod -R 755 /var/www/html

I know, very strange

s1lv3r

Doesn't look quite right to me, yet. :|

Aurelius

19:01

and that's what happens when I try to update

s1lv3r

and you have "direct" still in your wp-config?

Aurelius

yup

s1lv3r

I see.

Aurelius

the two lines below I tried before, didnt help so I commented them out

s1lv3r

Must work. :|

Lets try 775 ...

ummm ... this doesn't make any sense.

Aurelius

19:04

there must be a log somewhere with more detail on what directory it's trying to create?

s1lv3r

I'm pretty sure it must be SELinux.

Aurelius

okay, let's take a look

AHA

you are totally right!!!!
