一、安装jenkins需要jdk
先安装jdk-7u80-linux-x64.gz
1.上传jdk-7u80-linux-x64.gz到/opt/src目录。
2.执行安装脚本。
cat jdk.sh
#######################################################
cd /opt/src
tar zxvf jdk-7u80-linux-x64.gz
mv jdk1.7.0_80 /opt/java/
echo ‘export JAVA_HOME=/opt/java/’ >> /etc/profile
echo ‘export JRE_HOME=/opt/java/jre’ >> /etc/profile
echo ‘export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:$CLASSPATH’ >> /etc/profile
echo ‘export PATH=$JAVA_HOME/bin:$PATH’ >> /etc/profile
source /etc/profile
######################################################
使用java -version测试安装是否成功。
[root@localhost src]# java -version
java version “1.7.0_80”
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
二、安装jenkins。
1.下载jenkins
mkdir -p /opt/jenkins/jenkins_home
mkdir -p /opt/jenkins/jenkins_node
cd /opt/jenkins
2.启动jenkins
start_jenkins.sh
#!/bin/bash
JENKINS_ROOT=/home/AAA/jenkins
export JENKINS_HOME=$JENKINS_ROOT/jenkins_home
java -jar $JENKINS_ROOT/jenkins.war –httpPort=8000
chmod a+x start_jenkins.sh
测试启动，./start_jenkins.sh
报错：
[root@localhost jenkins]# ./start_jenkins.sh

说明JDK版本太低，更换jdk8版本。
安装过程略，测试版本。
[root@localhost src]# java -version
java version “1.8.0_121”
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
java version “1.8.0_121”
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
再进行启动测试。
启动正常，
后台启动 nohup ./start_jenkins.sh > jenkins.log 2>&1 &
打开12.0.65.110:8000进行安装。
