noexec and /tmp troubleshooting
|
|
-------------------------------
|
|
|
|
Many simple exploits that are used against servers rely upon being able
|
|
to execute commands in /tmp. As a security precaution, /tmp is mounted
|
|
with noexec. This is a good thing and should generally stay this way,
|
|
but jenkins doesn't think so, and it will give an error like:
|
|
"UnsatisfiedLinkError: ... failed to map segment from shared object".
|
|
|
|
In this situation, we need to edit file /usr/etc/jenkins.conf and add
|
|
"-Djava.io.tmpdir=/your/chrooted/tmp" into JENKINS_JAVA_OPTIONS variable.
