[root@Git ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
[root@Git ~]# uname -r
3.10.0-862.3.3.el7.x86_64
[root@Git ~]# systemctl stop firewalld
[root@Git ~]# systemctl disable firewalld
[root@Git ~]# systemctl stop NetworkManager
[root@Git ~]# systemctl disable NetworkManager
4.1 创建一个基于Pipeline流水线的项目
4.2 添加项目Git参数化构建
4.3 Pipeline脚本语法架构介绍
#Pipeline脚本语法架构
node ('slave节点名') { #被操控的节点服务器
def 变量 #def可以进行变量声明
stage('阶段名A'){ #流水线阶段一
执行步骤A
执行步骤B
执行步骤C
}
stage('阶段名B'){ #流水线阶段二
执行步骤A
执行步骤B
执行步骤C
}
stage('阶段名C'){ #流水线阶段三
执行步骤A
执行步骤B
执行步骤C
}
}
#流水线模板脚本
node {
def mvnHome
stage('Preparation') { // for display purposes
// Get some code from a GitHub repository
git 'https://github.com/jglick/simple-maven-project-with-tests.git'
// Get the Maven tool.
// ** NOTE: This 'M3' Maven tool must be configured
// ** in the global configuration.
mvnHome = tool 'M3'
}
stage('Build') {
// Run the maven build
if (isUnix()) {
sh "'${mvnHome}/bin/mvn' -Dmaven.test.failure.ignore clean package"
} else {
bat(/"${mvnHome}\bin\mvn" -Dmaven.test.failure.ignore clean package/)
}
}
stage('Results') {
junit '**/target/surefire-reports/TEST-*.xml'
archive 'target/*.jar'
}
}
4.4利用Pipeline Syntax,编写Pipeline Script并构建
(1)进入Pipeline Syntax
(2)通过脚本代码生成器,生成Pipeline脚本代码
(3)将生成的代码复制到流水线脚本相应步骤的stage函数里
(4)开始构建Pipeline项目
4.5 从远程仓库下载Pipeline Script,并构建
(1)在Git服务器上创建一个存放Pipeline脚本的仓库
[root@Git ~]# su - git
上一次登录:二 10月 23 18:59:42 CST 2018pts/0 上
[git@Git ~]$ cd /home/git/repos/
[git@Git repos]$ ls
app.git
[git@Git repos]$ mkdir jenkinsfile #创建存放Pipeline脚本的仓库
[git@Git repos]$ cd jenkinsfile/
[git@Git jenkinsfile]$ git --bare init #初始化仓库
初始化空的 Git 版本库于 /home/git/repos/jenkinsfile/
(2)在jenkins服务器上,往远程仓库提交一个Pipeline脚本。
[root@Jenkins ~]# mkdir /test
[root@Jenkins ~]# cd /test/
[root@Jenkins test]# git clone [email protected]:/home/git/repos/jenkinsfile
正克隆到 'jenkinsfile'...
warning: 您似乎克隆了一个空版本库。
[root@Jenkins test]# ls
jenkinsfile
[root@Jenkins test]# cd jenkinsfile/
[root@Jenkins jenkinsfile]# mkdir itemA
[root@Jenkins jenkinsfile]# vim itemA/jenkinsfile
[root@Jenkins jenkinsfile]# cat itemA/jenkinsfile
node {
def mvnHome
stage('Preparation') {
checkout([$class: 'GitSCM', branches: [[name: '${branch}']],
doGenerateSubmoduleConfigurations: false, extensions: [],
submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'f58165e3-e5a7-408a-a57d-a4b643b14308',
url: '[email protected]:/home/git/repos/app.git']]])
}
stage('maven Build') {
echo "maven build..."
}
stage('deploy') {
echo "deploy..."
}
stage('test') {
echo "test..."
}
}
#将脚本推送到远程仓库的master分支
[root@Jenkins jenkinsfile]# git add *
[root@Jenkins jenkinsfile]# git commit -m "第一次提交"
[master(根提交) 10fb59e] 第一次提交
1 file changed, 18 insertions(+)
create mode 100644 itemA/jenkinsfile
[root@Jenkins jenkinsfile]# git push -u origin master
Counting objects: 4, done.
Compressing objects: 100% (2/2), done.
Writing objects: 100% (4/4), 563 bytes | 0 bytes/s, done.
Total 4 (delta 0), reused 0 (delta 0)
To [email protected]:/home/git/repos/jenkinsfile
* [new branch] master -> master
分支 master 设置为跟踪来自 origin 的远程分支 master。
(3)利用远程仓库里的Pipeline脚本,进行流水线的构建

5.1 创建一个Pipeline流水线项目并进行参数化构建
由于我们仍旧打算将pipeline脚本放在远程Git仓库里,因此我们需要从远程Git仓库拉取Pipeline脚本,所以,参数化构建不支持Git的参数化。我们只能使用字符结构的参数化构建。
5.2 下载用于自动化发布的PHP源码wordpress源码包,并上传远程git仓库
#在Git服务器上创建用于存放源码的Git仓库
[root@Git ~]# hostname -I
192.168.200.61
[root@Git ~]# cd /home/git/repos/
[root@Git repos]# ls
app.git jenkinsfile
[root@Git repos]# mkdir wordpress
[root@Git repos]# cd wordpress/
[root@Git wordpress]# git --bare init
初始化空的 Git 版本库于 /home/git/repos/wordpress/
[root@Git wordpress]# cd ..
[root@Git repos]# ll -d wordpress
drwxr-xr-x 7 root root 119 10月 23 20:12 wordpress

#在jenkins服务器上,克隆创建好的远程Git仓库
[root@Jenkins ~]# mkdir /php-app
[root@Jenkins ~]# cd /php-app
[root@Jenkins php-app]# git clone [email protected]:/home/git/repos/wordpress

5.3 设置分布式构建的slave管理节点
我们计划利用分布式构建的方式,启动pipeline的流水线项目发布
slave管理节点就设置为需要用于发布项目的Web服务器
5.3.1 添加用于连接slave代理节点的SSH证书
5.3.2 添加并设置slave管理从节点
5.3.3 slave从节点安装java环境,并启动jenkins的slave管理节点
