You can assign larger disks to the tmp directory when you size the file system at the beginning of the machine installation.

Or create a soft link to the tmp directory. But all of these methods involve rebooting the computer.

Reassign the temporary space directory for jenkins by modifying the configuration file and parameters. Jenkins-mater configuration file / etc/sysconfig/jenkinsJENKINS_HOME= "/ data/opssino/jenkins" JENKINS_JAVA_OPTIONS= "- Djava.awt.headless=true-Djava.io.tmpdir=/var/tmp"

After the modification is completed, restart jenkins and the configuration of the primary node is complete.
