安装之前请确保你已经安装好JDK,Tomcat,Maven。
1、导入Jenkins key,安装
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
yum install jenkins
2、修改配置
[root@iZ94zsv4mnfZ ~]# vim /etc/sysconfig/jenkins
修改如下配置：
#避免执行脚本时权限不足
JENKINS_USER="root"
#默认为8080 与tomcat的端口冲突了这里我修改为8888，如你的8080端口未被占用，可以不改
JENKINS_PORT="8888"
JENKINS_USER我这里设置了root需要为root赋予访问jenkins的权限
[root@iZ94zsv4mnfZ ~]# chown -R root /var/log/jenkins
[root@iZ94zsv4mnfZ ~]# chgrp -R root /var/log/jenkins
[root@iZ94zsv4mnfZ ~]# chown -R root /var/lib/jenkins
[root@iZ94zsv4mnfZ ~]# chgrp -R root /var/lib/jenkins
[root@iZ94zsv4mnfZ ~]# chown -R root /var/cache/jenkins
[root@iZ94zsv4mnfZ ~]# chgrp -R root /var/cache/jenkins
再修改另一处配置
[root@iZ94zsv4mnfZ ~]# vim /etc/init.d/jenkins
找到
candidates="
/etc/alternatives/java
/usr/lib/jvm/java-1.6.0/bin/java
/usr/lib/jvm/jre-1.6.0/bin/java
/usr/lib/jvm/java-1.7.0/bin/java
/usr/lib/jvm/jre-1.7.0/bin/java
/usr/lib/jvm/java-1.8.0/bin/java
/usr/lib/jvm/jre-1.8.0/bin/java
/usr/bin/java
在/usr/bin/java上面添加一行：/usr/java/jdk1.8.0_102/bin/java 前面是你的java安装路径。
最终如下
candidates="
/etc/alternatives/java
/usr/lib/jvm/java-1.6.0/bin/java
/usr/lib/jvm/jre-1.6.0/bin/java
/usr/lib/jvm/java-1.7.0/bin/java
/usr/lib/jvm/jre-1.7.0/bin/java

/usr/lib/jvm/jre-1.8.0/bin/java
/usr/java/jdk1.8.0_102/bin/java
/usr/bin/java
3启动
[root@iZ94zsv4mnfZ ~]# service jenkins start
启动完成后即可登录http://IP:8888/访问Jenkins
第一次登录Jenkins 会要求解锁
