rpm包安装方式

一、准备需要用到的包：

apache-maven-3.5.0-bin.tar.gz
官网下载：https://maven.apache.org/download.cgi#

jdk-8u121-linux-x64.tar.gz
官网下载：http://www.oracle.com/technetwork/java/javase/downloads/

jenkins-2.7.4-1.1.noarch.rpm
官网下载：https://jenkins.io/download/

二、开始安装

解压包
tar xf jdk-8u121-linux-x64.tar.gz -C /usr/local/
tar xf apache-maven-3.5.0-bin.tar.gz -C /usr/local/   //可选，构建源码需要这个
rpm -ivh jenkins-2.7.4-1.1.noarch.rpm
 
重命名
mv apache-maven-3.5.0 maven
mv apache-tomcat-8.5.13 tomcat
mv jdk1.8.0_121 jdk1.8
 
配置环境变量
###############
export JAVA_HOME=/usr/local/jdk1.8
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/jre/lib/rt.jar
export PATH=$PATH:/usr/local/maven/bin
export JENKINS_HOME="/var/lib/jenkins"
 
source /etc/profile  或者   . /etc/profile  使环境变量生效
 
查看java版本
[root@localhost ~]# 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)
 
修改Jenkins 启动脚本文件
vim /etc/init.d/jenkins
candidates="/usr/local/jdk1.8/bin/java    //添加上你的java路径
/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
"
 
启动jenkins
[root@localhost ~]# service jenkins start
Starting Jenkins                      [ OK ]
 
查看端口号
[root@localhost ~]# netstat -lntp 
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address               Foreign Address             State       PID/Program name   
tcp        0      0 0.0.0.0:22                  0.0.0.0:*                   LISTEN      1070/sshd           
tcp        0      0 127.0.0.1:25                0.0.0.0:*                   LISTEN      1147/master

tcp        0      0 ::1:25                      :::*                        LISTEN      1147/master

三、访问初始化jenkins

[root@localhost ~]# cat /var/lib/jenkins/secrets/initialAdminPassword

war 包安装方式

一、准备需要用到的包：

apache-maven-3.5.0-bin.tar.gz
官网下载：https://maven.apache.org/download.cgi#

jdk-8u121-linux-x64.tar.gz
官网下载：http://www.oracle.com/technetwork/java/javase/downloads/

jenkins-2.46.1.war
官网下载：https://jenkins.io/download/

二、开始安装

解压
tar xf jdk-8u121-linux-x64.tar.gz -C /usr/local/
tar xf apache-tomcat-8.5.13.tar.gz -C /usr/local/
tar xf apache-maven-3.5.0-bin.tar.gz -C /usr/local/   //可选，构建源码需要这个

重命名
mv apache-maven-3.5.0 maven
mv apache-tomcat-8.5.13 tomcat
mv jdk1.8.0_121 jdk1.8

移动war包到webapps目录
mv /source/jenkins.war /usr/local/tomcat/webapps/

配置环境变量
###############
export JAVA_HOME=/usr/local/jdk1.8
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/jre/lib/rt.jar
export PATH=$PATH:/usr/local/maven/bin
export JENKINS_HOME="/root/.jenkins"

source /etc/profile  或者   . /etc/profile  使环境变量生效

查看java版本
[root@localhost ]# java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)

三、访问配置jenkins

http://192.168.23.253:8080/jenkins/

web界面初始化 和 rpm包界面是一样的
