Is that not awful advice? If he can't cd to /tmp for whatever reason will it not rm -rf * his login directory?


yeah true, though I don't recall anyone ever getting denied accessing tmp as root..

Ok, first do.....

cd /tmp

then run this line once you confirmed your in /tmp.. service httpd stop;service mysql stop;rm -rf *;service mysql start;service httpd start;
 

Hi Borgan

there is enough space i just need to know what size of tmp files exactly is causing this problem so can determine what size i should set my temp folder to
disk.webp

SSH in as root.. run this.. service httpd stop;service mysql stop;cd /tmp;rm -rf *;service mysql start;service httpd start;

Hi Mike
even if i empty the /tmp now it will be filled again at any time soon and get the same issue

Yeah but he could typo your command and try to cd into /tnp or something. Just thought it was better to be safe like you've changed it to above :-)
 
This is likely MySQL temp tables being written.

The best thing to do is create a directory like
mkdir /home/mysqltmp
chown mysql:mysql /home/mysqltmp
Then put the following in /etc/my.cnf under [mysqld]
tmpdir=/home/mysqltmp
and restart MySQL.

When you run
mysqladmin variables|grep tmpdir

you should now see this

# mysqladmin variables|grep tmpdir
| tmpdir | /home/mysqltmp |
#
 
after I move the MySQL tmp to /home/mysqltmp do i still need /tmp size to stay 2GB or I can reduce it back to 1GB like before? Because I am recieving DISKWAR emails that /dev/sda3 is 83%


Before decreasing it, I'd assure it was MySQL causing it.

Run this again..

cd /tmp

then run this line once you confirmed your in /tmp.. service httpd stop;service mysql stop;rm -rf *;service mysql start;service httpd start;

Then wait a day and see how much space you use and then make it double of that size.

Thank you very much for your advise. since that date I never had this problem
