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  :: CST  from 192.168.200.132 on pts/
Last failed login: Tue Dec  :: CST  from 192.168.200.132 on ssh:notty
There were  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

[root@jenkins jenkinsfile]# cd itemA
[root@jenkins itemA]# vim jenkinsfile
[root@jenkins itemA]# cat jenkinsfile
node {
  // def mvnHome
   stage('git checkout') {
    checkout([$class: 'GitSCM',
    branches: [[name: '${branch}']],
    doGenerateSubmoduleConfigurations: false,
    extensions: [], submoduleCfg: [],

    url: 'git@192.168.200.151:/home/git/repos/app.git']]])
   }
   stage('maver Build') {
        echo "build ..."
   }
   stage('deploy') {
        echo "success"
   }
    stage('test') {
        echo "ok"
    }
}
[root@jenkins itemA]# cd ..
[root@jenkins jenkinsfile]# git add *

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
.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=(apache) gid=(apache) groups=(apache)
[root@nginx-php html]# id nginx
uid=(nginx) gid=(nginx) groups=(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
tcp    LISTEN                  *:                    *:*                   users:(("nginx",pid=,fd=),("nginx",pid=,fd=))
tcp    LISTEN                 :::                   :::*                   users:(("nginx",pid=,fd=),("nginx",pid=,fd=))
[root@nginx-php nginx]# ss -antup | grep
tcp    LISTEN               127.0.0.1:                  *:*                   users:(("php-fpm",pid=,fd=),("php-fpm",pid=,fd=),("php-fpm",pid=,fd=),("php-fpm",pid=,fd=),("php-fpm",pid=,fd=),("php-fpm",pid=,fd=))
[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..0_171/ jdk
[root@nginx-php local]# vim /etc/profile
[root@nginx-php local]# tail - /etc/profile

构建分布式节点

修改流水线项目的配置

编写流水线脚本

在Jenkins上修改流水线脚本，并推到git上

[root@jenkins ~]# cd /test/jenkinsfile/itemA/
[root@jenkins itemA]# cp jenkinsfile jenkinsfile-php
[root@jenkins itemA]# vim jenkinsfile-php
[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'''

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'
    }

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。
