On RPM-based distributions, such as Red Hat Enterprise Linux (RHEL), CentOS, Fedora or Scientific Linux, you can install Jenkins through yum. Recent versions are available in a YUM repository. InstallationAdd the Jenkins repository to the yum repos, and install Jenkins from here.
Installation of a stable versionThere is also a LTS YUM repository for the LTS Release Line
Installation of JavaJenkins requires Java in order to run, yet certain distros don‘t include this by default. To install the Open Java Development Kit (OpenJDK) run the following: sudo yum install java Note: If running CentOS, ensure you follow the guide below. Start/Stop
Note: if you get the following error message, ensure that Java has been installed: Starting jenkins (via systemctl): Job for jenkins.service failed. See ‘systemctl status jenkins.service‘ and ‘journalctl -xn‘ for details. [FAILED] What does this package do?
Disable the firewallfirewall-cmd --zone=public --add-port=8080/tcp --permanent firewall-cmd --zone=public --add-service=http --permanent firewall-cmd --reload firewall-cmd --list-all Important Note on CentOS JavaJenkins requires Java in order to run, however yum install jenkins does not enforce that java is already installed. Check to make sure that you already hava java installed by running java -version. To further make things difficult for CentOS users, the default CentOS version of Java is not compatible with Jenkins. Jenkins typically works best with a Sun implementation of Java, which is not included in CentOS for licensing reasons. If you get output similar to the following, it means you‘re using the default (GCJ) version of Java, which will not work with Jenkins: java -version java version "1.5.0" gij (GNU libgcj) version 4.4.6 20110731 (Red Hat 4.4.6-3) To correct this, you may need to remove the GCJ version of Java and install a Sun-compatible version. If you received the above output, uninstall the default java: yum remove java Then after you‘ve uninstalled Java (or if you didn‘t have Java installed at all to begin with). You need to install a Sun-compatible version of Java. The easiest approach is using OpenJDK, which is available through the EPEL repository (alternatively you may install an official RPM directly from Oracle). To install OpenJDK run the following: yum install java-1.7.0-openjdk Depending on your version of CentOS, the package name for OpenJDK may differ. Use yum search openjdk to check for the name of the package. If OpenJDK is not found at all through yum, you probably need to install the EPEL yum repository. After installation, you should be able to get the following output for java -version: java -version java version "1.7.0_79" OpenJDK Runtime Environment (rhel-2.5.5.1.el6_6-x86_64 u79-b14) OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode) |
