jenkins的流水线pipeline+项目实验php
声明：实验环境使用Jenkins的应用与搭建的环境
新建一个流水线
pipeline脚本语法架构 node（'slave节点名'）{ def 变量 #def可以进行变量声明 stage('阶段名A'){ #流水线阶段1 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2 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3 执行步骤A 执行步骤B 执行步骤C } }
用流水线脚本来构建流水线
首先在git服务器上建立放置流水线脚本的git仓库
[root@git ~]# su - git Last login: Sun Dec 23 13:49:25 CST 2018 from 192.168.200.132 on pts/1 Last failed login: Tue Dec 25 14:03:45 CST 2018 from 192.168.200.132 on ssh:notty There were 2 failed login attempts since the last successful login. [git@git ~]$ ls repos [git@git ~]$ cd repos/ [git@git repos]$ ls app.git [git@git repos]$ mkdir -p jenkinsfile [git@git repos]$ cd jenkinsfile/ [git@git jenkinsfile]$ git --bare init Initialized empty Git repository in /home/git/repos/jenkinsfile/ [git@git jenkinsfile]$ ls branches config description HEAD hooks info objects refs [git@git jenkinsfile]$
在Jenkins服务器上上传流水线脚本到git仓库
[root@jenkins ~]# cd /test/ [root@jenkins test]# ls app [root@jenkins test]# git clone git@192.168.200.151:/home/git/repos/jenkinsfile Cloning into 'jenkinsfile'... warning: You appear to have cloned an empty repository.

修改web上的Jenkins的流水线的配置
实验自动流水线php实验
需要多备一台服务器php，搭建，
ngin-php服务器： IP地址 192.168.200.152 操作系统centos7.5
用yum安装Nginx，php，
[root@nginx-php ~]# yum -y install epel-release nginx php-fpm php-mysql git
修改Nginx的配置文件
[root@nginx-php ~]# cd /etc/nginx/ [root@nginx-php nginx]# egrep -v "#|^$" nginx.conf >> nginx.conf.bak [root@nginx-php nginx]# mv nginx.conf /tmp/ [root@nginx-php nginx]# mv nginx.conf.bak nginx.conf [root@nginx-php nginx]# vim nginx.conf [root@nginx-php nginx]# cat nginx.conf user nginx; worker_processes auto; error_log /var/log/nginx/error.log; pid /run/nginx.pid; include /usr/share/nginx/modules/*.conf; events { worker_connections 1024; } http { log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; include /etc/nginx/mime.types; default_type application/octet-stream; include /etc/nginx/conf.d/*.conf; server { listen 80; server_name www.yunjisuan.com; root /usr/share/nginx/htm/www.yunjisuan.com; include /etc/nginx/default.d/*.conf; location / { index index.html index.php index.htm; } location ~\.php { fastcgi_index index.php; fastcgi_pass 127.0.0.1:9000; include fastcgi.conf; } } } [root@nginx-php nginx]#
[root@nginx-php nginx]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
创建Nginx的首页目录
[root@nginx-php nginx]# cd /usr/share/nginx/html/ [root@nginx-php html]# ls 404.html 50x.html index.html nginx-logo.png poweredby.png [root@nginx-php html]# rm -rf * [root@nginx-php html]# mkdir -p www.yunjisuan.com [root@nginx-php html]# echo "192.168.200.152 www.yunjisuan.com" >> /etc/hosts [root@nginx-php html]# id apache uid=48(apache) gid=48(apache) groups=48(apache) [root@nginx-php html]# id nginx uid=998(nginx) gid=996(nginx) groups=996(nginx) [root@nginx-php html]# cd .. [root@nginx-php nginx]# chown -R apache html [root@nginx-php nginx]#
启动Nginx，php
[root@nginx-php nginx]# systemctl start nginx [root@nginx-php nginx]# systemctl start php-fpm [root@nginx-php nginx]# ss -antup | grep 80 tcp LISTEN 0 128 *:80 *:* users:(("nginx",pid=6435,fd=6),("nginx",pid=6434,fd=6)) tcp LISTEN 0 128 :::80 :::* users:(("nginx",pid=6435,fd=7),("nginx",pid=6434,fd=7)) [root@nginx-php nginx]# ss -antup | grep 9000 tcp LISTEN 0 128 127.0.0.1:9000 *:* users:(("php-fpm",pid=6448,fd=0),("php-fpm",pid=6447,fd=0),("php-fpm",pid=6446,fd=0),("php-fpm",pid=6445,fd=0),("php-fpm",pid=6444,fd=0),("php-fpm",pid=6442,fd=6)) [root@nginx-php nginx]#
安装jjdk，maven
[root@nginx-php ~]# tar xf jdk-8u171-linux-x64.tar.gz -C /usr/local/ [root@nginx-php ~]# cd /usr/local/ [root@nginx-php local]# mv jdk1.8.0_171/ jdk [root@nginx-php local]# vim /etc/profile [root@nginx-php local]# tail -3 /etc/profile export JAVA_HOME=/usr/local/jdk/ export PATH=$PATH:$JAVA_HOME/bin export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar [root@nginx-php local]# source /etc/profile [root@nginx-php local]#ln -s /usr/local/jdk/bin/java /usr/bin/
[root@nginx-php ~]# tar xf apache-maven-3.5.0-bin.tar.gz -C /usr/local/ [root@nginx-php ~]# cd /usr/local/ [root@nginx-php local]# mv apache-maven-3.5.0/ maven [root@nginx-php local]# vim /etc/profile [root@nginx-php local]# tail -2 /etc/profile MAVEN_HOME=/usr/local/maven export PATH=${MAVEN_HOME}/bin:$PATH [root@nginx-php local]# source /etc/profile
在git服务器上建立php的远程仓库
[root@git ~]# su - git Last login: Tue Dec 25 14:47:07 CST 2018 on pts/1 Last failed login: Tue Dec 25 14:57:42 CST 2018 from 192.168.200.132 on ssh:notty There were 2 failed login attempts since the last successful login.

在Jenkins上准备上传代码到git仓库
[root@jenkins ~]# cd /test/ [root@jenkins test]# git clone git@192.168.200.151:/home/git/repos/wordpress Cloning into 'wordpress'... warning: You appear to have cloned an empty repository.

构建分布式节点
修改流水线项目的配置

重新构建
多节点流水线，需要修改流水线脚本，几个节点，就将原来的节点复制几份，将节点修改了，拉代码是在同一台服务器拉所以不用改。（另外的个节点需要安装的工具，参考Nginx的。）配置脚本如下
[root@jenkins itemA]# cat jenkinsfile-php node ("PHP-slave-192.168.200.152") { // def mvnHome stage('git php checkout') { checkout([$class: 'GitSCM', branches: [[name: '${branch}']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '3d9f3769-3fc9-4e9f-b6c3-b3a93f894d36', url: 'git@192.168.200.151:/home/git/repos/wordpress']]]) } stage('copy') { sh '''rm -rf ${WORKSPACE}/.git [ -d /data/backup ] || mkdir -p /data/backup mv /usr/share/nginx/html/www.yunjisuan.com /data/backup/www.yunjisuan.com-$(date +%F_%T) cp -rf ${WORKSPACE} /usr/share/nginx/html/www.yunjisuan.com''' } stage('test') { sh 'curl http://www.yunjisuan.com/status.html' } } node ("PHP-slave-192.168.200.153") {#第二个节点，就是节点名字改了其余的都是复制第一个节点的 // def mvnHome stage('git php checkout') { checkout([$class: 'GitSCM', branches: [[name: '${branch}']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '3d9f3769-3fc9-4e9f-b6c3-b3a93f894d36', url: 'git@192.168.200.151:/home/git/repos/wordpress']]]) } stage('copy') { sh '''rm -rf ${WORKSPACE}/.git [ -d /data/backup ] || mkdir -p /data/backup mv /usr/share/nginx/html/www.yunjisuan.com /data/backup/www.yunjisuan.com-$(date +%F_%T) cp -rf ${WORKSPACE} /usr/share/nginx/html/www.yunjisuan.com''' } stage('test') { sh 'curl http://www.yunjisuan.com/status.html' } } node ("PHP-slave-192.168.200.154") { #第3给节点，就是节点名字改了，其余的都是复制第一个节点的 // def mvnHome stage('git php checkout') { checkout([$class: 'GitSCM', branches: [[name: '${branch}']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '3d9f3769-3fc9-4e9f-b6c3-b3a93f894d36', url: 'git@192.168.200.151:/home/git/repos/wordpress']]]) } stage('copy') { sh '''rm -rf ${WORKSPACE}/.git [ -d /data/backup ] || mkdir -p /data/backup mv /usr/share/nginx/html/www.yunjisuan.com /data/backup/www.yunjisuan.com-$(date +%F_%T) cp -rf ${WORKSPACE} /usr/share/nginx/html/www.yunjisuan.com''' } stage('test') { sh 'curl http://www.yunjisuan.com/status.html' } } [root@jenkins itemA]#
直接构建就可以了
让节点通过ssh支持执行命令道web服务器的，流水线，需要装插件
即节点拉取代码到本地，节点将代码发送到web服务器，通过ssh，执行写在本地的叫本在web服务器上。
在Jenkins上修改流水线脚本
[root@jenkins itemA]# pwd /test/jenkinsfile/itemA [root@jenkins itemA]# ls jenkinsfile jenkinsfile-php jenkinsfile-php.bak [root@jenkins itemA]# cat jenkinsfile-php node ("PHP-slave-192.168.200.152") { def remote = [:] remote.name = 'test' remote.user = 'root' remote.allowAnyHosts = true stage('git php checkout') { sh 'echo "`hostname -I`"' checkout([$class: 'GitSCM', branches: [[name: '${branch}']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '3d9f3769-3fc9-4e9f-b6c3-b3a93f894d36', url: 'git@192.168.200.151:/home/git/repos/wordpress']]]) } // stage('copy') { // sh '''rm -rf ${WORKSPACE}/.git // [ -d /data/backup ] || mkdir -p /data/backup // mv /usr/share/nginx/html/www.yunjisuan.com /data/backup/www.yunjisuan.com-$(date +%F_%T) // cp -rf ${WORKSPACE} /usr/share/nginx/html/www.yunjisuan.com''' //} // stage('test') { // sh 'curl http://www.yunjisuan.com/status.html' // } stage ('SSH 200.151') { remote.host = '192.168.200.151' remote.password = '123123' writeFile file: 'ssh.sh', text:'echo "`hostname -I`"' sshScript remote:remote, script: "ssh.sh" } } [root@jenkins itemA]#
