/etc/cron.daily/netdata-updater: line 225: ./netdata-installer.sh: Permission denied
Tue Nov 3 03:38:03 +08 2020 : ERROR: FAILED TO UPDATE NETDATA : FAILED TO COMPILE/INSTALL NETDATA
/tmp is mounted as noexec on CentOS 7.
Any workaround for this? Thanks
if i edit netdata-updater.sh won’t work because this file will be replaced somehow. So in the end i define TMPDIR in ~/.bash_profile, and source this profile while running custom cron.
0 * * * * source ~/.bash_profile; /usr/libexec/netdata/netdata-updater.sh
cron.daily]# ./netdata-updater

i assume this works?
I still receiving /tmp permission denied email though, that should be the script running at cron.daily which doesn’t work. Any way to disable auto updater?
Is there an open issue in the github repo? I couldn’t find one.
Back then we had that problem and it was fixed in kickstart: noexec detection by paulfantom · Pull Request #5293 · netdata/netdata · GitHub, but a lot of had changed since then, could be we reverted those changes duriing refactoring or something
alright thanks for the update. For the time being i’ll just apply workaround to updater. Let’s monitor.
/etc/cron.daily/netdata-updater
export TMPDIR=/root/netdata/tmp
Hello @ethaniel86 ,
As @OdysLam said, this is a problem that we are working to fix. On CentOS 7 in normal situation it is not allowed to run any script inside /tmp, and some users decided to disable noexec on it, but this can also be a security problem. We will need to change our installation script to use a different directory to run the updates.
Best regards!
Hey @ethaniel86,
There is an active issue: the source directory does not include netdata-installer.sh · Issue #9863 · netdata/netdata · GitHub which might be related. Please be patient as I speak with our engineers, they should be back here to reply promptly!

For anyone else running into this problem, I looked through the source of /etc/cron.daily/netdata-updater (which may have changed since this 2020 thread) and see that it checks for a NETDATA_TMPDIR_PATH environment variable, and will use that in preference to TMP_DIR. So, we can define something like this in /etc/anacrontab so it is defined before any of the cron.daily etc. scripts are run:
NETDATA_TMPDIR_PATH=/root/tmp
