I am getting error unable to connect with mysql. when I googled I found It's because of size. It's showing /tmp 100% used. so can I completely remove all files from/tmp folder ?

#df -m /tmp

 Filesystem     1M-blocks  Used Available Use% Mounted on

 /dev/xvda1         40184 38508         0 100% /

I have following files

stderr (44.3 KB)

file7bJPfk (0B)

root@cloud-server-02:~# df -h
Filesystem      Size  Used Avail Use% Mounted on

    Your / file system is full, /tmp is only a subdir of that. – Sven May 7 '15 at 8:29
  • thanks @Sven although i have deleted 500MB data from 4)Gb server still it shows 100% when i do df -h? – kamlesh.bar May 7 '15 at 8:54

Stop you critical services and cleanup folder. The tmp directory is cleared by default at every boot. During deletion you may face with files which are in use, you can skip them.

    Let me clearify something....Clearing of /tmp area is NOT automatic nor default as this depends on how the system is put configured. If /tmp is configured in the swap space this is basically an artifact of rebooting, but the startup scripting does not do this. If /tmp is resident on a standard filesystem, then the files/directories persist between reboots. – mdpc May 7 '15 at 8:29

    By default files in tmp deletes at every boot. Check /etc/default/rcS – Maxiko May 7 '15 at 9:06
