redhat安装jenkins

安装jenkins:

jenkins与java版本支持:
2.54 (2017-04) and newer: Java 8
1.612 (2015-05) and newer: Java 7

Add the Jenkins repository to the yum repos, and install Jenkins from here.
	sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
	wget https://jenkins-ci.org/redhat/jenkins-ci.org.key
	sudo rpm --import jenkins-ci.org.key
	sudo yum install jenkins

安装java:

检查java版本:
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)

安装java:
yum remove java
yum install java-1.7.0-openjdk

此结果java安装成功:
[root@CentOS ~]# java -version
java version "1.7.0_95"
OpenJDK Runtime Environment (rhel-2.6.4.0.el6_7-i386 u95-b00)
OpenJDK Client VM (build 24.95-b01, mixed mode, sharing)

Start/Stop jenkins:

sudo service jenkins start/stop/restart
sudo chkconfig jenkins on

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]
