配置全局设置

如果想通过curl命令，远程发送请求的方式触发Jenkins进行调度，需要关闭全局安全设置中的防止跨站点请求伪造

全局工具配置

在安装Jenkins时，需要提前将JDK、Maven以及Git环境安装在你的机器中。下面是一些配置细节：

JDK 安装

# 安装命令
$ yum install java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64
$ yum install java-1.8.0-openjdk-devel-1.8.0.191.b12-0.el6_10.x86_64
# 查看命令
[root@longsl jvm]# rpm -qa | grep java
java-1.8.0-openjdk-1.8.0.191.b12-0.el6_10.x86_64
java-1.8.0-openjdk-headless-1.8.0.191.b12-0.el6_10.x86_64
java-1.8.0-openjdk-devel-1.8.0.191.b12-0.el6_10.x86_64

Git installations

Maven 安装

$ wget http://mirrors.sonic.net/apache/maven/maven-3/3.6.0/binaries/apache-maven-3.6.0-bin.tar.gz

# Ensure JAVA_HOME environment variable is set and points to your JDK installation
$ vim /etc/profile
export JAVA_HOME="/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el6_10.x86_64"
export PATH="$JAVA_HOME/bin:$PATH"

export MAVEN_HOME="/opt/maven-3.6"
export PATH="$MAVEN_HOME/bin:$PATH"

$ tar xzvf apache-maven-3.6.0-bin.tar.gz

# 查看命令
[root@longsl maven-3.6]# mvn --version
Apache Maven 3.6.0 (97c98ec64a1fdfee7767ce5ffb20918da4f719f3; 2018-10-25T02:41:47+08:00)
Maven home: /opt/maven-3.6
Java version: 1.8.0_191, vendor: Oracle Corporation, runtime: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el6_10.x86_64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "4.16.12-1.el6.elrepo.x86_64", arch: "amd64", family: "unix"

安装Jenkins

下载Jenkins

进入Jenkins官方下载站点 https://jenkins.io/download/

$ wget http://mirrors.jenkins.io/war-stable/latest/jenkins.war

启动Jenkins

$ mkdir -p /var/log/jenkins/ /var/cache/jenkins/ /root/jenkins/
$ sudo nohup /etc/alternatives/java -Djava.awt.headless=true -DJENKINS_HOME=/root/jenkins -jar /root/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --httpPort=8082 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20 &

上面通过java命令来启动的好处：Jenkins运行和Tomcat服务器进行分离，另外可以在启动的时候自定义端口号和日志输出路径等。

解锁jenkins

cat /root/jenkins/secrets/initialAdminPassword

安装Jenkins Plugin

配置Jenkins任务 - deploy web project

源码管理

通过git来管理源码，这里填入Repositories中的URL和Credentials

Maven构建

Pre Steps

Build

Root POM：deploy/pom.xml
Goals and options：clean package -Pdev

Run only if build succeeds

sudo rm -rf /usr/app/tomcat/webapps/deploy && sudo cp -f ${WORKSPACE}/deploy/target/deploy.war /usr/app/tomcat/webapps && sudo systemctl restart tomcat
