Each Linux server has a diretcory named \/tmp which is installed with individual file system. it is used to hold temporary files. \/tmp directory have all the all the website session files which is hosted on serve.<\/span><\/p>\n

so if we removed those file incorrectly the user session got disconnected who is currently using database. Some times the \/tmp directory got full, so you can\u2019t write anything to mysql database and you start getting error messages. To resolve this you have to remove some content\/files from \/tmp directory<\/a> to free space.<\/span><\/p>\n

First of all you can check \/tmp directory to find out what kind of files stored there.<\/span><\/p>\n

<\/div>\n
\n
root@server [\/tmp]# ls -lh\r\ntotal 50M\r\ndrwxrwxrwt 15 root root 508K May 6 13:26 .\/\r\ndrwxr-xr-x 29 root root 4.0K May 3 03:32 ..\/\r\n-rw------- 1 cppl cppl 1.8K 19 Sep 6 05:48 sess_01677a0944c23187135748f09037f13a\r\n-rw------- 1 cppl cppl 19 Sep 6 13:22 sess_0292d1af394d15f09e5565af76304acd<\/pre>\n<\/div>\n
<\/div>\n
In my server \/tmp<\/a> folder have only session file, so i\u2019m going to remove only session files.<\/span><\/p>\n
Shell script to clean session files:<\/span><\/h3>\n
For this purpose we can use the simple shell script and assign to cron once in a day.<\/span><\/p>\n
<\/div>\n
\n
#!\/bin\/bash\r\n\r\nrm -rf \/tmp\/sess_*\r\n\/sbin\/service mysql restart<\/pre>\n<\/div>\n
<\/div>\n
Just create the shell file called tmpclean.sh at \/etc\/cron.daily<\/strong> folder and put the above codes. It will clean the session files once in a day and restart the mysql service.<\/span>
\n Make sure your shell file have executable permissions (755).<\/span><\/p>\n
Clean \/tmp folder without affecting anything ?<\/span><\/h3>\n
Many script creates session files after every seconds. You can use mtime argument with the find command to search out little bit old files say 1 hour older. So if you remove them it doesn’t effect much to your websites.<\/span><\/p>\n
<\/div>\n
\n
#!\/bin\/bash\r\n\r\nfind \/tmp\/sess_* -mtime +1h -exec rm {} \\;<\/pre>\n<\/div>\n
<\/div>\n
Just create the shell file called tmpclean.sh at \/etc\/cron.hourly<\/strong> folder and put the above codes. It will clean the session files every one hour. Make sure your shell file should have executeable permission (755).<\/span><\/p>\n
That\u2019s all we have to do clean up the \/tmp folder contents in Linux servers\u00a0 Please give your opinion below if you experience any issues or to discuss your ideas and\u00a0experiences.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
