 Posted: Fri Feb 21, 2003 2:11 am Post subject: mysql-4.0.10 ebuild bug - unable to create mysql.sock - help |
 |
|
After emerging dev-db/mysql-4.0.10 on a fresh install of Gentoo. Mysqld fails to run (/etc/init.d/mysql start) with the following error in mysql.log
| Code: | 030221 01:49:43 mysqld started
030221 1:49:43 Can't start server : Bind on unix socket: Permission denied
030221 1:49:43 Do you already have another mysqld server running on socket: /var/run/mysqld/mysqld.sock ?
030221 1:49:43 Aborting
030221 1:49:43 /usr/sbin/mysqld: Shutdown Complete
030221 01:49:43 mysqld ended
|
If I alter the mysql my.cnf to have mysqld run as root, mysql runs fine. Must be a privilege problem then right?
| Code: | # ls -ld /var/log/mysql/ /var/run/mysqld/ /var/lib/mysql/
drwxr-xr-x 5 mysql mysql 176 Feb 21 01:25 /var/lib/mysql/
drwxr-xr-x 2 mysql mysql 112 Feb 19 23:44 /var/log/mysql/
drwxr-xr-x 2 mysql mysql 48 Feb 21 01:55 /var/run/mysqld/
|
Running strace /usr/sbin/mysqld --user=mysql yields:
| Code: | bind(4, {sin_family=AF_UNIX, path="/var/run/mysqld/mysqld.sock"}, 110) = -1 EACCES (Permission denied)
|
It is obviously having problems creating mysql.sock in /var/run/mysqld but the privileges apprear correct. What am I missing? 
Update: I do have Grsecurity installed.
Update: just compiled a new kernel without Grsecurity, same problem.

Yes, I think it must be a permissions problem. Does the other user account (i.e. not root) have the appropriate permissions to create sockets? I'm relatively new to linux, but I think this is the problem. Google for sockets and linux and see what comes up. Sorry I can't be more specific but I don't really know the answer.

Problem solved:
Turns out that the root of / was not executable after doing a Gentoo stage-1 install. After the install the root looked like this:
| Code: | # ls -la /
drwx------ 18 root root 536 Feb 21 23:15 .
more... |
The Fix:
| Code: | # chmod a+x /
# ls -la /
drwx--x--x 18 root root 536 Feb 21 23:15 .
more... |
Why is it that the obvious stuff is so hard to find? Hope this helps someone else out there. I would like to thank Dean at www.homelan.com for helping me debug this. |
