I checked Memory capacity,swap capacity, restart service, upgrade jenkins, permission directories But jenkins status is "Active(exited)" and couldn't access to application. How can i resolve this issue? (OS: CentOS 7)
It is because of a version conflict of installed Jenkins. You probably upgraded the version of Jenkins by just copying .war file into /usr/lib/jenkins/ path.
You may solve the problem via installing the required version using the following example command:
rpm -Uvh jenkins-2.138.2-1.1.noarch.rpm
