7340 lighttpd's mod_fastcgi won't execute .php files

[Michael999]

Lighttpd reads e.g. html files fine, but it won't execute .php files. Anytime I try to execute a .php file the following error is given in the log:

--------------
2011-04-24 13:32:19: (log.c.166) server started

--------------

/var/run/lighttpd/php-fastcgi.socket-0 (+1,2) do exist. Just to make sure it wasn't a permission thing I did a "chown -R wwwrun:wwwrun" on /var/run/lighttpd and, because wwwrun runs lighttpd. I also did a chmod -R 777 on /var/run/lighttpd. This made no diference though, as the same errors are given in the log. What's the cause of this?

Also, I'd like to add that when I try to compile lighttpd with the module "enable locks in mod_webdav" it fails to compile and gives this error:

--------------
cp: cannot stat `source/target-mips_uClibc-0.9.29/lighttpd-1.4.28/src/.libs/mod_webdav.so': No such file or directory

Perhaps you can try to do a console login with user wwwrun. Go to /var/run/lighttpd and try to create a file?

Oliver

edit: [mod_webdav] Please have a look into ...lighttpd-1.4.28/config.log and search for mod_webdav?

 

[Michael999]

I tried to login with "wwwrun" from the console using no password and wwwrun as password, but it just says "login incorrect". This corresponds with "cat /etc/passwd" which says:

wwwrun:x:1001:4:lighttpd account:/home/wwwrun:/bin/false

which shows user wwwrun has no shell access. Or am I doing something wrong here?


On mod_webdav, "mod_webdav" occurs twice in lighttpd-1.4.28/config.log :

configure:13722: checking for properties in mod_webdav
configure:13732: result: yes

......

configure:13930: checking for locks in mod_webdav
configure:13940: result: yes

I tried out lighttpd and it works for me (but I don't own a 7340):

And mod_webdav is built, too.

Why is your gid so low?

 

[Michael999]

Thank you for answering olistudent .

I tried all kinds of things, like changing the socket path, recreating user wwwrun, playing with php's memory settings (I read somewhere those are relevant to socket errors), but I can't get it to work.

The strange thing is, when I first posted the socket files were created in "/var/run/lighttpd", even though I still got those "permission denied" errors in the log and "503 - Service Not Available" / "500 - Internal Server Error" in the browser. Now however they're not created at all when loading .php files.

root@fritz:/var/run# ls -l /var/run/*light*
-rw-r--r--    1 root     root             6 Apr 26 16:05 /var/run/lighttpd.pid

/var/run/lighttpd:

php-cgi processes are started:

root@fritz:/var/run# ps | egrep -e "light|php" |grep -v grep
18288 wwwrun    4272 S    lighttpd -f /mod/etc/lighttpd/lighttpd.conf
18289 wwwrun    9276 S    /usr/bin/php-cgi
18297 wwwrun    9276 S    /usr/bin/php-cgi
18298 wwwrun    9276 S    /usr/bin/php-cgi
18308 wwwrun    9276 S    /usr/bin/php-cgi
18309 wwwrun    9276 S    /usr/bin/php-cgi
18314 wwwrun    9276 S    /usr/bin/php-cgi

Manually creating them didn't work either:

root@fritz:/var/run# touch /var/run/lighttpd/php-fastcgi.socket-0
root@fritz:/var/run# touch /var/run/lighttpd/php-fastcgi.socket-1
root@fritz:/var/run# touch /var/run/lighttpd/php-fastcgi.socket-2
root@fritz:/var/run# chmod -R 777 /var/run/lighttpd
root@fritz:/var/run# chown -R wwwrun:wwwrun /var/run/lighttpd
root@fritz:/var/run# lighttpd -f /mod/etc/lighttpd/lighttpd.conf

lighttpd error log after trying to load .php file:

2011-04-26 14:27:32: (mod_fastcgi.c.1734) connect failed: Permission denied on unix:/var/run/lighttpd/php-fastcgi.socket-2

2011-04-26 14:27:34: (mod_fastcgi.c.2785) fcgi-server re-enabled:  0 /var/run/lighttpd/php-fastcgi.socket

I'm not sure what else to try. This is the fastcgi part of lighttpd.conf:

server.modules += ( "mod_fastcgi" )
fastcgi.server = (
        ".php" => (( "socket" => "/var/run/lighttpd/php-fastcgi.socket", "bin-path" => "/usr/bin/php-cgi", "max-procs" => 3 ))
)

mod_webdav still won't compile. I'll try a fresh trunk, maybe that'll help with this.

Should the GID be higher?

root@fritz:/var/run# cat /etc/group
root:x:0:
users:x:1:
nobody:x:2:
openvpn:x:3:
wwwrun:x:4:
sshd:x:1000:
ftpsec:x:1002:
web:x:1004:

 

[olistudent]

What are the permissions of your /var/run/lighttpd?

# ls -l |grep light
drwx------    2 wwwrun   wwwrun           0 Apr 26 15:18 lighttpd
-rw-r--r--    1 root     root             6 Apr 26 15:18 lighttpd.pid
# ls -l /var |grep run
drwxr-xr-x    6 root     root             0 Apr 26 16:38 run

GID: I wondered because mine seem to start at 1000. But that should only be cosmetic.

 

[Michael999]

root@fritz:/var/run# ls -l |grep light
drwxrwxrwx    2 wwwrun   wwwrun         100 Apr 26 16:24 lighttpd
-rw-r--r--    1 root     root             6 Apr 26 16:27 lighttpd.pid

Edit: by using a fresh trunk, mod_webdav is built. Still have the same lighttpd/fastcgi problem though.

 

[olistudent]

Perhaps you can attach strace to your lighttpd and post a log. But I think there have to be some permissions wrong on the way to /var/run/lighttpd...

Regards
Oliver

 

[Michael999]

I attached an strace log of lighttpd when trying to load a .php file. You appear to be right, it seems to be a permission problem, but what's the solution?

[olistudent]

Please post the permissions of /var, /var/run and /var/run/lighttpd. Something has to be different compared to other (my) firmwares.

After a reboot /var/run/lighttpd is gone and isn't recreated by lighttpd.

The /var/run/lighttpd I talked about earlier:

root@fritz:/var/run# ls -l |grep light
drwxrwxrwx    2 wwwrun   wwwrun         100 Apr 26 16:24 lighttpd
-rw-r--r--    1 root     root             6 Apr 26 16:27 lighttpd.pid

I created it, as I said, manually for that reason. That didn't make a difference. So is it perhaps a permission thing higher in the tree?

 

[olistudent]

I wanted to see the permissions of the directories not of their contents. ;-)

/var/run/lighttpd should be create automatically!?

 

[Michael999]

After a reboot lighttpd and php-cgi are running:

root@fritz:/var/mod/root# ps | egrep -e "light|php"|grep -v grep

but:

ls: /var/run/lighttpd: No such file or directory

Trying to load a .php file doesn't create /var/run/lighttpd either.

 

[olistudent]

I'm running out of ideas...

Do you use the chrooted version? But this works for me too. Perhaps you can post your lighttp configuration?

Regards
Oliver

 

[Michael999]

I use the chrooted version. lighttpd.conf attached.

[olistudent]

Then the sockets are created in /var/media/ftp/uStor05/ext/www/htdocs/var/run/lighttpd. Please look at the permissions of ustor5, ext, www and htdocs path.

Regards
Oliver

 

[stan23]

Which filesystem is uStor05 using?
I had a problem chrooting on an USB stick with FAT32, because some device-nodes (I don't remember exactly) cannot be created on FAT32.

 

[RalfFriedl]

because some device-nodes cannot be created on FAT32.

Any device-nodes cannot be created on FAT32.
Also no sockets and no pipes.

 

[Michael999]

uStor05 is using ext2:

root@fritz:/var/mod/root# mount|egrep uStor05
/dev/sda5 on /var/media/ftp/uStor05 type ext2 (rw,noatime,nodiratime)

Directory permissions:
