搭建jenkins

1.wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo 
2.rpm --import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key 
3.yum install jenkins
4.yum install java-1.8.0-openjdk

配置

vim /etc/sysconfig/jenkins
    JENKINS_PORT="8080"
    JENKINS_JAVA_CMD="$candidate"
    JENKINS_USER="root"

下载java

去官方下载jdk包(https://www.oracle.com/java/technologies/javase-downloads.html)
解压到/usr/bin/java里面

vim /etc/profile
    #java environment
    export JAVA_HOME=/usr/bin/java/jdk-15.0.1
    export CLASSPATH=.:${JAVA_HOME}/jre/lib/rt.jar:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar
    export PATH=$PATH:${JAVA_HOME}/bin
source /etc/profile


vim  /etc/init.d/jenkins

    /setup/tools/jdk1.8.0_144/bin/java #此处为加入的java路径
    /etc/alternatives/java
    /usr/lib/jvm/java-1.8.0/bin/java
    /usr/lib/jvm/jre-1.8.0/bin/java
    /usr/lib/jvm/java-1.7.0/bin/java
    /usr/lib/jvm/jre-1.7.0/bin/java
    /usr/bin/java/jdk-15.0.1/bin/java
    
systemctl daemon-reload
service jenkins start

登录并加载

初次的密码
cat /var/lib/jenkins/secrets/initialAdminPassword

添加秘钥

其中一个比较重要的点就是你的git仓库的ssh的秘钥要添加一个环境代码仓库的对应的JENKINS_USER的秘钥

jenkins配置项目

在jenkins中新建项目，绑定git，
也可以自己追加相关构建脚本，
    像是composer update之类的
    然后把目录cp到真正的项目目录
    或者推送到其他的代码服务器等操作
