Pipeline流水线介绍

创建一个基于Pipeline流水线的项目

添加项目Git参数化构建

Git Parameter插件不支持流水线，版本过低

Pipeline脚本语法架构介绍

1. #Pipeline脚本语法架构
3. node （'slave节点名'） { #被操控的节点服务器
5. def 变量 #def可以进行变量声明
7. stage（'阶段名A'）{ #流水线阶段一
8. 执行步骤A
9. 执行步骤B
10. 执行步骤C
11. }
13. stage（'阶段名B'）{ #流水线阶段二
14. 执行步骤A
15. 执行步骤B
16. 执行步骤C
17. }
19. stage（'阶段名C'）{ #流水线阶段三
20. 执行步骤A
21. 执行步骤B
22. 执行步骤C
23. }
24. }

流水线模板脚本

1. node {
2. def mvnHome
3. stage('Preparation') { // for display purposes
4. // Get some code from a GitHub repository
5. git 'https://github.com/jglick/simple-maven-project-with-tests.git'
6. // Get the Maven tool.
7. // ** NOTE: This 'M3' Maven tool must be configured
8. // ** in the global configuration.
9. mvnHome = tool 'M3'
10. }
11. stage('Build') {
12. // Run the maven build
13. if (isUnix()) {
14. sh "'${mvnHome}/bin/mvn' -Dmaven.test.failure.ignore clean package"
15. } else {
16. bat(/"${mvnHome}\bin\mvn" -Dmaven.test.failure.ignore clean package/)
17. }
18. }
19. stage('Results') {
20. junit '**/target/surefire-reports/TEST-*.xml'
21. archive 'target/*.jar'
22. }
23. }

1. node {
2. //def mvnHome
3. stage('checkout') { // for display purposes
4. checkout([$class: 'GitSCM', branches: [[name: '${branch}']],
5. doGenerateSubmoduleConfigurations: false,
6. extensions: [], submoduleCfg: [],
7. userRemoteConfigs: [[credentialsId: '9f98962f-1a82-4da1-8a0f-bc906e92d998',
8. url: '[email protected]:/home/git/repos/app.git']]])
9. }
10. stage('maven Build') {
11. echo "maven build ..."
12. }
13. stage('deploy') {
14. echo "deploy..."
15. }
16. stage('test') {
17. echo "test..."
18. }
19. }

利用Pipeline Syntax，编写Pipeline Script并构建

（1）进入Pipeline Syntax

1. node {
2. //def mvnHome
3. stage('checkout') { // for display purposes
5. }
6. stage('maven Build') {
7. echo "maven build ..."
8. }
9. stage('deploy') {
10. echo "deploy..."
11. }
12. stage('test') {
13. echo "test..."
14. }
15. }

（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

1. checkout([$class: 'GitSCM', branches: [[name: '${branch}']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '9f98962f-1a82-4da1-8a0f-bc906e92d998', url: '[email protected]:/home/git/repos/app.git']]])

（4）开始构建Pipeline项目

（5）在Jenkins本地服务器查看拉取结果

cd /var/lib/jenkins/workspace

ls

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

su - git

cd /home/git/repos/

pwd

ls

mkdir jenkinsfile #创建存放Pipeline脚本的仓库

cd jenkinsfile/

git --bare init #初始化仓库

（2）在jenkins服务器上，往远程仓库提交一个Pipeline脚本。

mkdir /test

cd /test

git clone [email protected]:/home/git/repos/jenkinsfile

ls

cd jenkinsfile/

mkdir itemA

vim itemA/jenkinsfile

cat itemA/jenkinsfile

1. node {
2. //def mvnHome
3. stage('checkout') { // for display purposes
4. checkout([$class: 'GitSCM', branches: [[name: '${branch}']],
5. doGenerateSubmoduleConfigurations: false,
6. extensions: [], submoduleCfg: [],
7. userRemoteConfigs: [[credentialsId: '9f98962f-1a82-4da1-8a0f-bc906e92d998',
8. url: '[email protected]:/home/git/repos/app.git']]])
9. }
10. stage('maven Build') {
11. echo "maven build ..."
12. }
13. stage('deploy') {
14. echo "deploy..."
15. }
16. stage('test') {
17. echo "test..."
18. }
19. }

将脚本推送到远程仓库的master分支

git add *

git commit -m "jenkinsfile"

git push -u origin master

（3）利用远程仓库里的Pipeline脚本，进行流水线的构建

（4）在jenkins服务器上查询拉取代码结果(之前清空过jenkins下的workspace工作目录)

cd /var/lib/jenkins/workspace/

ls

cd A-PHP

项目案例一：Jenkins+Pipeline+Git+PHP博客项目流水线自动发布

所有服务器进行如下操作

cat /etc/redhat-release

uname -r

systemctl stop firewalld

systemctl disable firewalld

systemctl stop NetworkManager

systemctl disable NetworkManager

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。

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

hostname -I

cd /home/git/repos/

ls

mkdir wordpress

cd wordpress/

git --bare init

cd ..

ll

chown -R git.git wordpress

在jenkins服务器上，克隆创建好的远程Git仓库

mkdir /php-app

cd /php-app

git clone [email protected]:/home/git/repos/wordpress

ls

在jenkins服务器上，下载wordpres源代码

链接：https://pan.baidu.com/s/1hGyd1xFuL0oPBsFeROuUYQ 
提取码：tmgk --->wordpress百度云下载地址

wget https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz

cd /php-app/wordpress/

ls

tar xf wordpress-4.9.4-zh_CN.tar.gz

ls

mv wordpress-4.9.4-zh_CN.tar.gz /tmp/

ls

mv wordpress/* .

rm -rf wordpress/

ls

在jenkins上提交代码到远程Git仓库

git add *

git commit -m "第一次提交"

git push -u origin master

设置分布式构建Web服务器的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

添加用于连接slave代理节点的SSH证书(上文已经设置过了)

添加并设置Web服务器的slave管理从节点

Web服务器slave从节点安装java环境，并启动jenkins的slave管理节点

链接：https://pan.baidu.com/s/1EXO2hSetnkapR29ojJIGTg 
提取码：ixgn --->jdk百度云下载地址

解压安装jdk

tar xf jdk-8u60-linux-x64.tar.gz -C /usr/local/

cd /usr/local

mv jdk1.8.0_60/ jdk

/usr/local/jdk/bin/java -version

配置java环境

sed -i.org '$a export JAVA_HOME=/usr/local/jdk/' /etc/profile

sed -i.org '$a export PATH=$PATH:$JAVA_HOME/bin' /etc/profile

sed -i.org '$a export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar' /etc/profile

tail -3 /etc/profile

source /etc/profile

java -version

重新启动Slave从节点

Web服务器安装LNMP环境，并手动拉取代码模拟访问

yum -y install epel-release

yum -y install nginx php-fpm php-mysql

修改nginx配置文件

cd /etc/nginx/

ls

cp nginx.conf{,.bak}

egrep -v "#|^$" nginx.conf.bak > nginx.conf

cat nginx.conf

1. user nginx;
2. worker_processes auto;
3. error_log /var/log/nginx/error.log;
4. pid /run/nginx.pid;
5. include /usr/share/nginx/modules/*.conf;
6. events {
7. worker_connections 1024;
8. }
9. http {
10. log_format main '$remote_addr - $remote_user [$time_local] "$request" '
11. '$status $body_bytes_sent "$http_referer" '
12. '"$http_user_agent" "$http_x_forwarded_for"';
13. access_log /var/log/nginx/access.log main;
14. sendfile on;
15. tcp_nopush on;
16. tcp_nodelay on;
17. keepalive_timeout 65;
18. types_hash_max_size 2048;
19. include /etc/nginx/mime.types;
20. default_type application/octet-stream;
21. include /etc/nginx/conf.d/*.conf; #include了一个配置文件目录
22. server {
23. listen 80 default_server; #默认的server配置（如果用IP访问就进入这个server）
24. listen [::]:80 default_server;
25. server_name _;
26. root /usr/share/nginx/html; #默认的网页目录
27. include /etc/nginx/default.d/*.conf;
28. location / {
29. }
30. error_page 404 /404.html;
31. location = /40x.html {
32. }
33. error_page 500 502 503 504 /50x.html;
34. location = /50x.html {
35. }
36. }
37. }

由于默认的配置文件include了/etc/nginx/conf.d/*.conf因此我们增加一个server配置文件即可

vim /etc/nginx/conf.d/wp.conf

cat /etc/nginx/conf.d/wp.conf

1. server {
2. listen 80;
3. server_name www.yunjisuan.com;
4. root /usr/share/nginx/html/www.yunjisuan.com;
5. location / {
6. index index.php index.html;
7. }
8. location ~\.php {
9. fastcgi_index index.php;
10. fastcgi_pass 127.0.0.1:9000;
11. include fastcgi.conf;
12. }
13. }

创建网页目录

cd /usr/share/nginx/html/

ls

mkdir www.yunjisuan.com

cd www.yunjisuan.com

ls

克隆Git仓库代码到本地网页目录

yum -y install git

git init

git clone [email protected]:/home/git/repos/wordpress

ls

mv wordpress/* .

ls

rm -rf wordpress/

将网页目录权限授权给apache程序用户

cd ..

ll

id apache

chown -R apache.apache /usr/share/nginx/html/www.yunjisuan.com

启动nginx服务和php-fpm服务

systemctl start nginx

systemctl start php-fpm

ss -antup | egrep "80|9000"

systemctl enable nginx

systemctl enable php-fpm

做好宿主机的域名映射后，浏览器访问测试

在远程Git仓库中创建一个用于构建的Pipeline脚本

在jenkins服务器上进行如下操作

rm -rf /test

mkdir /test

cd /test

git clone [email protected]:/home/git/repos/jenkinsfile

ls

cd jenkinsfile/

ls

ls itemA/

通过流水线脚本生成器生成如下脚本内容

vim itemA/jenkinsfile-php-wp

cat itemA/jenkinsfile-php-wp

1. node ("PHP-slave1-192.168.200.101") {
2. stage('git checkout') {
3. checkout([$class: 'GitSCM',
4. branches: [[name: '${branch}']],
5. doGenerateSubmoduleConfigurations: false, extensions: [],
6. submoduleCfg: [], userRemoteConfigs: [[credentialsId: '9f98962f-1a82-4da1-8a0f-bc906e92d998',
7. url: '[email protected]:/home/git/repos/wordpress']]])
8. }
9. stage('code copy') {
10. sh '''rm -rf ${WORKSPACE}/.git
11. [ -d /data/backup ] || mkdir -p /data/backup
12. mv /usr/share/nginx/html/www.yunjisuan.com /data/backup/www.yunjisuan.com-$(date +%F_%T)
13. cp -rf ${WORKSPACE} /usr/share/nginx/html/www.yunjisuan.com'''
14. }
15. stage('test') {
16. sh 'curl http://www.yunjisuan.com/status.html'
17. }
18. }

推送到Git远程仓库

git add *

git commit -m "xxx"

git push -u origin master

通过流水线脚本生成器生成的阶段代码示例（这里只生成了url部分，具体内容自定义）

在Web服务器上PHP项目代码里增加Pipeline验证用的测试页面

在项目代码里加入一个健康检查测试页面，并推送到远程Git仓库

cd /var/lib/jenkins

git clone [email protected]:/home/git/repos/wordpress

ls

cd wordpress/

ls

echo "OK-version V2.0" >> status.html

将测试用页面提交到远程Git仓库

git add *

git commit -m "version V2.0"

git config --global user.email "112340"

git config --global user.name "Mr.sun"

git push -u origin master

在web服务器做域名映射（因为要进行curl验证）

echo "`hostname -I` www.yunjisuan.com" >> /etc/hosts

cat /etc/hosts

浏览器访问jenkins进行PHP项目流水线发布构建

流水线项目发布多节点需要注意的事项

所需要修改的部分如下

脚本需要在流水线脚本写出多节点，比如

1. node ("PHP-slave1-192.168.200.101") {
2. stage('git checkout') {
3. checkout([$class: 'GitSCM',
4. branches: [[name: '${branch}']],
5. doGenerateSubmoduleConfigurations: false, extensions: [],
6. submoduleCfg: [], userRemoteConfigs: [[credentialsId: '9f98962f-1a82-4da1-8a0f-bc906e92d998',
7. url: '[email protected]:/home/git/repos/wordpress']]])
8. }
9. stage('code copy') {
10. sh '''rm -rf ${WORKSPACE}/.git
11. [ -d /data/backup ] || mkdir -p /data/backup
12. mv /usr/share/nginx/html/www.yunjisuan.com /data/backup/www.yunjisuan.com-$(date +%F_%T)
13. cp -rf ${WORKSPACE} /usr/share/nginx/html/www.yunjisuan.com'''
14. }
15. stage('test 200.101-php') {
16. sh 'curl http://www.yunjisuan.com/status.html'
17. }
18. }
20. node ("PHP-slave1-192.168.200.xxx") {
21. stage('git checkout') {
22. checkout([$class: 'GitSCM',
23. branches: [[name: '${branch}']],
24. doGenerateSubmoduleConfigurations: false, extensions: [],
25. submoduleCfg: [], userRemoteConfigs: [[credentialsId: '9f98962f-1a82-4da1-8a0f-bc906e92d998',
26. url: '[email protected]:/home/git/repos/wordpress']]])
27. }
28. stage('code copy') {
29. sh '''rm -rf ${WORKSPACE}/.git
30. [ -d /data/backup ] || mkdir -p /data/backup
31. mv /usr/share/nginx/html/www.yunjisuan.com /data/backup/www.yunjisuan.com-$(date +%F_%T)
32. cp -rf ${WORKSPACE} /usr/share/nginx/html/www.yunjisuan.com'''
33. }
34. stage('test' 200.xxx-php) {
35. sh 'curl http://www.yunjisuan.com/status.html'
36. }
37. }

假如是克隆的机器需要把hosts文件里的映射修改一下

在浏览器进入jenkins主用户来添加新节点信息（有几点节点就添加几个）

所有的修改都完事以后，在进行构建测试就可以了

让ssh支持流水线，需要安装插件SSH Pipeline Steps

以ssh方式分发流水线脚本模板详解

1. def remote = [:] #定义变量不需要改
2. remote.name = 'test' #远程主机的名字
3. remote.host = 'test.domain.com' #远程主机的IP
4. remote.user = 'root' #远程主机的用户
5. remote.password = 'password' #远程主机的密码
6. remote.allowAnyHosts = true #照着超就可以
7. stage('Remote SSH') { #阶段名称
8. writeFile file: 'abc.sh', text: 'ls -lrt' #把后面的命令,让如abc.sh脚本里
9. sshScript remote: remote, script: "abc.sh" #把脚本分发自定义的主机
10. }

以ssh方式分发流水线脚本语法样式

1. node ("PHP-slave1-192.168.200.101") {
2. def remote = [:]
3. remote.name = 'test'
4. remote.user = 'root'
5. remote.allowAnyHosts = true
6. stage('git checkout') {
7. sh `echo "`hostname -I`"`
8. checkout([$class: 'GitSCM',
9. branches: [[name: '${branch}']],
10. doGenerateSubmoduleConfigurations: false, extensions: [],
11. submoduleCfg: [], userRemoteConfigs: [[credentialsId: '9f98962f-1a82-4da1-8a0f-bc906e92d998',
12. url: '[email protected]:/home/git/repos/wordpress']]])
13. }
14. stage('SSH 200.xxx') {
15. remote.host = '192.168.200.xxx'
16. remote.password = 'linyaonie'
17. writeFile file: 'ssh01.sh', text:'echo "`hostname -I`"'
18. sshScript remote:remote, script: "ssh01.sh"
19. }
20. stage('SSH 200.xxx') {
21. remote.host = '192.168.200.xxx'
22. remote.password = 'linyaonie'
23. writeFile file: 'ssh02.sh', text:```
24. echo "`hostname -I`"
25. echo "`hostname -I`"
26. echo "`hostname -I`"
27. ``` --->这里需要注意要定格写
28. sshScript remote:remote, script: "ssh02.sh"
29. }
30. }

重新把新修过的内容添加到远程仓库并构建测试在查看logs日志的结果

git add *

git commit -m "测试SSH"

git push -u origin master
