1.概述

2.Java安装

cd /opt
wget --no-check-certificate 
tar xvf jdk-8u131-solaris-x64.tar.gz

设置环境变量

cd /opt
wget --no-check-certificate 
tar xvf jdk-8u131-solaris-x64.tar.gz
vim ~/.bashrc

在最后添加如下代码

#set oracle jdk environment
export JAVA_HOME=/opt/jdk1.8.0_131
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH 

使配置生效

source ~/.bashrc

验证java是否安装成功

java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

3.Jenkins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 -y install jenkins

此时查看Jenkins状态，发现没起来，究其原因是java路径不对，修改配置文件：

vi /etc/rc.d/init.d/jenkins 

在“/usr/bin/java”下添加如下行

/opt/jdk1.8.0_131/bin/java  #根据自己的java路径而定

保存退出
重新加载配置文件

systemctl --deamon-reload

开启Jenkins

systemctl start jenkins.service

永久开放8080/tcp端口

firewall-cmd --add-port=8080/tcp --permanent
firewall-cmd --reload

打开浏览器输入：ip:8080/jenkins
即可看到初始化界面
