mysqld’ failed to start.
A detailed log from /var/log/mysqld.log file:

/etc/init.d/mysql start command returned following output:
Initializing MySQL database: [ OK ] Timeout error occurred trying to start MySQL Daemon.
Starting MySQL: [FAILED]
How do I fix this problem on Linux or Unix-like systems?
This error means, MySQL server is not able to access your /tmp directory, to write and create temporary files. Make sure /tmp directory is owned by root user and sticky bit is set on /tmp directory. Type the following commands to fix this error. You must be login as root user and type:
# chown root:root /tmp
# chmod 1777 /tmp
## test it ##
# /etc/init.d/mysqld start
Now, your mysql server should start without a problem.
A note about SELinux and AppArmor security policies
If you are using SELinux or AppArmor with customized data directory for database, you need to modify polices to allow MySQL to read and write to the data directory.

Hi,
The problem was solved and the issue was about the computer name. They named their computer as com1,com2 and com3. MySQL server started to run after i renamed their system.

I have the same problem,
here is a query I want to execute,
mysql> select * from remote into outfile ‘/home/nshaikh/mysql_out/outfile.txt’;
ERROR 1 (HY000): Can’t create/write to file ‘/home/nshaikh/mysql_out/outfile.txt’ (Errcode: 13)
I have changed the permission of file to ‘777’;
I tried with ‘root’ and some other user ‘dump’, executing this command in mysql interactive shell,
please
reply with your valuable answers.
Thank you,
Thanks – saved a lot of trouble !
Hi,
I have another user for database say ‘navid’. How can I grant it permission to write to directory as in this case ‘/tmp’ ?
is ‘/tmp’ is only directory where we can set permissions for db users to write into or other directories can also be made writable?
thank you.
Thank you very much, you saved me.
Thanks Dude!
Fix the problem.
Thanks alot. I was able to fix the problem.
this worked. fixed my problems with mysql. thanks!
Thanks man. You saved a hell lot of time for me :)
Its like any directory you want to access through mysql should be owned by root and permission set as 777.
Thanks !!
GRACIAS!! thx!!
Thanks.
Thank you
You saved my day !!!
thanks
In my case it´s working, a big THX for your great hint … :-)
Thanks a lot!
