一、安装包下载：

1. jdk-8u152-linux-x64.tar.gz下载：

    wget http://download.oracle.com/otn-pub/java/jdk/8u152-b16/aa0333dd3019491ca4f6ddbe78cdb6d0/jdk-8u152-linux-x64.tar.gz?AuthParam=1510049032_894becb76e01031b3099aafc33c5a06c

2. maven-3/3.3.9下载：

    wget http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz

3. jenkins-2.88-1.1下载：

    wget https://prodjenkinsreleases.blob.core.windows.net/redhat/jenkins-2.88-1.1.noarch.rpm

二、安装

1. jdk安装：

tar -zxvf jdk-8u152-linux-x64.tar.gz

然后拷贝至自己安装软件的地方（我的是：/home/work/zach/soft/jdk1.8.0_152）

2. maven安装：

tar -zxvf apache-maven-3.3.9-bin.tar.gz

然后拷贝至自己安装软件的地方（我的是：/home/work/zach/soft/maven）

3. jenkins安装：

rpm -ivh jenkins-2.88-1.1.noarch.rpm

jenkins默认安装至 /var/lib/jenkins

三、配置：

1. jdk与maven：

vim /etc/profile

unset i

unset -f pathmunge

export JAVA_HOME=/home/work/zach/soft/jdk1.8.0_152

export MAVEN_HOME=/home/work/zach/soft/maven

export JRE_HOME=${JAVA_HOME}/jre

export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib

export PATH=$JAVA_HOME/bin:$MAVEN_HOME/bin:$PATH

保存后执行：source /etc/profile

2. 启动jenkins前需修改 /etc/rc.d/init.d/jenkins:

vim /etc/rc.d/init.d/jenkins

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

/home/work/zach/soft/jdk1.8.0_152/bin/java

"

加粗为修改的地方

四、权限问题

1. Open up the this script (using VIM or other editor):

vim /etc/sysconfig/jenkins

2. Find this $JENKINS_USER and change to “root”:

$JENKINS_USER="root"

3. Then change the ownership of Jenkins home, webroot and logs:

chown -R root:root /var/lib/jenkins

chown -R root:root /var/cache/jenkins

chown -R root:root /var/log/jenkins

4) Restart Jenkins and check the user has been changed:

service jenkins restart
