Jenkins Pipeline部署SpringBoot应用的步骤

yum install -y wget
yum install -y gcc-c++
yum install -y zlib-devel perl-ExtUtils-MakeMaker
yum -y install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker
yum install -y openssh-clients
yum install -y fontconfig

yum -y install java-1.8.0-openjdk
#检测是否安装成功
java -version

vi /etc/profile
在文件的最后面，加上以下代码
export JAVA_HOME=/java/jdk1.8.0_171
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$PATH

#下载
wget http://mirrors.hust.edu.cn/apache/maven/maven-3/3.1.1/binaries/apache-maven-3.1.1-bin.tar.gz
#解压改名移动目录
tar zxf apache-maven-3.1.1-bin.tar.gz 
mv apache-maven-3.1.1 /usr/local/maven3

export M2_HOME=/usr/local/maven3
export PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin

#重载服务（由于前面修改了Jenkins启动脚本）
sudo systemctl daemon-reload

#启动Jenkins服务
sudo systemctl start jenkins

#将Jenkins服务设置为开机启动
#由于Jenkins不是Native Service，所以需要用chkconfig命令而不是systemctl命令
sudo /sbin/chkconfig jenkins on
