Centos 7 最小化部署jenkins

前言

jenkins是devops与CI/CD的重要工具之一，下面通过jenkins与svn的结合完成自动部署功能

环境

软件	名称	版本
操作系统	Centos	7.4
开发环境	jdk	1.8
中间件	tomcat	8.5
构建仓库	maven	3.5
版本控制	subversion	1.7
持续交付	jenkins	2.7

部署

准备工作

关闭防火墙与selinux，设备需要联网，因为maven构建的时候需要下载大量的jar包

systemctl stop firewalld.service
systemctl disable firewalld.service
sed -i 's/enforcing/disabled/g' /etc/sysconfig/selinux
reboot

安装jdk

rpm -qa | grep "java" | xargs rpm -e -nodeps
rpm -qa | grep "tzdata" | xargs rpm -e --nodeps
rpm -ivh jdk-8u45-linux-x64.rpm
java -version

java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

安装tomcat

tar -zxf apache-tomcat-8.5.24.tar.gz -C /usr/local/
cd /usr/local
mv apache-tomcat-8.5.24 tomcat

安装maven工具

wget http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.3.9/binaries/ apache-maven-3.5.2-bin.tar.gz 
tar -zxf apache-maven-3.5.2-bin.tar.gz -C /usr/
cd /usr
mv apache-maven-3.5.2 maven

安装jenkins

wget http://mirrors.tuna.tsinghua.edu.cn/jenkins/war-stable/2.73.2/jenkins.war
rm -rf /usr/local/tomcat/webapps/ROOT
mkdir -p /usr/local/tomcat/webapps/ROOT
mv jenkins.war /usr/local/tomcat/webapps/ROOT
cd /usr/local/tomcat/webapps/ROOT
jar -xf jenkins.war
mkdir /jenkins
cd /usr/local/tomcat/bin
./startup.sh

添加环境变量

vim /etc/profile
# 添加如下内容：
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin
MAVEN_HOME=/usr/maven
JENKINS_HOME=/jenkins
PATH=/usr/maven/bin:/usr/java/jdk1.8.0_45/bin:/usr/java/jdk1.8.0_45/jre/bin:$PATH
export PATH JENKINS_HOME MAVEN_HOME

# 将环境变量加入到内存中
source /etc/profile
echo $PATH
/usr/maven/bin:/usr/java/jdk1.8.0_45/bin:/usr/java/jdk1.8.0_45/jre/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:
