安裝git

yum install -y git

安裝maven與ant

wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
yum -y install apache-maven
yum -y install ant

在centos7上安裝Jenkins

安裝

新增yum repos，然後安裝

sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
sudo rpm --import
 
 https://jenkins-ci.org/redhat/jenkins-ci.org.key
sudo yum install jenkins

啟動和停止

sudo service jenkins start/stop/restart
sudo chkconfig jenkins on

修改jenkins啟動使用者

vi /etc/sysconfig/jenkins

JENKINS_USER=”jenkins”改成JENKINS_USER=”root”

這樣就是以root使用者啟動了

修改jenkins埠

vi /etc/sysconfig/jenkins

JENKINS_PORT=”8080”

最後儲存，重啟jenkins服務

service jenkins restart

安裝maven外掛

系統設定–管理外掛

publish over ssh

系統管理–系統設定

新增 SSH Servers

點選儲存

新建任務–

配置git地址

構建觸發條件—-*/3 * * * *  每更新程式碼3秒後更新

build選項中使用一下命令不執行單元測試用例（clean install -Dmaven.test.skip=true）

設定構建前刪除專案的target目錄（rm -rf /var/lib/jenkins/workspace/business/target/）

設定工具成功後操作—（

mv /var/lib/jenkins/workspace/business/target/business-*.jar /var/lib/jenkins/workspace/business/target/business.jar;

yes|cp /var/lib/jenkins/workspace/business/target/business.jar /opt/tomcat/webapps/business.jar;

cd /opt/pj/;

BUILD_ID=dontKillMe nohup ./restart.sh &

）無輸出執行jar

設定構建成功後ssh遠端程式碼操作—（

mv /opt/sshcache/business.jar /opt/pj/business.jar;

./restart.sh > nohup.out &

）拷貝程式碼-執行重啟jar指令碼不要輸出
