jenkins流水线项目发布流程

jenkins流水线项目发布流程

环境说明

主机名称 IP地址 需要的应用服务 工具包 系统版本
node1 192.168.110.14 tomcat、jenkins git、maven redhat 8
node2 192.168.110.13 tomcat 无 redhat

准备工作

关闭防火墙和selinux

//node1和node2

systemctl disable --now firewalld
sed -ri 's/^(SELINUX=).*/\1disabled/g' /etc/sysconfig/selinux
setenforce 0

在node1主机部署服务（Tomcat、jenkins）

1. 把Tomcat和jenkins包使用xftp传到本机node1

image

//node1
#在本机查看一下
[root@node1 ~]# ls
anaconda-ks.cfg  apache-tomcat-9.0.46.tar.gz  jenkins.war

2. 部署Tomcat容器和jenkins项目

//node1
#安装java环境
[root@node1 ~]# yum -y install java-11-openjdk

#安装工具包
[root@node1 ~]# yum -y install maven git

#解压安装包，创建jenkins项目
[root@node1 ~]# tar xf apache-tomcat-9.0.46.tar.gz 
[root@node1 ~]# ls
anaconda-ks.cfg  apache-tomcat-9.0.46  apache-tomcat-9.0.46.tar.gz  jenkins.war
[root@node1 ~]# mkdir -p /usr/local/tomcat/jenkins
[root@node1 ~]# cp -r apache-tomcat-9.0.46/* /usr/local/tomcat/jenkins/      
[root@node1 ~]# cp jenkins.war /usr/local/tomcat/jenkins/webapps/

#启动jenkins项目
[root@node1 ~]# /usr/local/tomcat/jenkins/bin/catalina.sh start
Using CATALINA_BASE:   /usr/local/tomcat/jenkins
Using CATALINA_HOME:   /usr/local/tomcat/jenkins
Using CATALINA_TMPDIR: /usr/local/tomcat/jenkins/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/tomcat/jenkins/bin/bootstrap.jar:/usr/local/tomcat/jenkins/bin/tomcat-juli.jar
Using CATALINA_OPTS:   
Tomcat started.
[root@node1 ~]# ss -antl
State     Recv-Q    Send-Q            Local Address:Port       Peer Address:Port    
LISTEN    0         128                     0.0.0.0:22              0.0.0.0:*       
LISTEN    0         128                        [::]:22                 [::]:*       
LISTEN    0         1            [::ffff:127.0.0.1]:8005                  *:*       
LISTEN    0         100                           *:8080                  *:*

在node2主机部署服务

1. 在node1主机上生成一个密钥，传给node2主机

//node1
#生成密钥，直接回车4下
[root@node1 ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:gns7tHucexs/lfoIp5e07uMYi9HO1ozGOZeiPenOtkg root@node1
The key's randomart image is:
+---[RSA 3072]----+
|                 |
|                 |
|                 |
|     .           |
|    . . S      . |
|     ... .  . o  |
|    ...oEo=B.*   |
|     .oo+O&X%.   |
|      o+=X&%*+.  |
+----[SHA256]-----+

#密钥传给node2
[root@node1 ~]# ssh-copy-id root@192.168.110.13
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
The authenticity of host '192.168.110.13 (192.168.110.13)' can't be established.
ECDSA key fingerprint is SHA256:+UR5bwjFNEKZsJ+X/qSSsMGCvtq5ByludUEL47JqwoU.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@192.168.110.13's password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'root@192.168.110.13'"
and check to make sure that only the key(s) you wanted were added.

2. 部署Tomcat

//node1
#使用scp命令把Tomcat包传给node2
[root@node1 ~]# scp apache-tomcat-9.0.46.tar.gz root@192.168.110.13:/root/
apache-tomcat-9.0.46.tar.gz                       100%   11MB  42.6MB/s   00:00 

//node2
#安装java环境
[root@node2 ~]# yum -y install java-11-openjdk

#查看
[root@node2 ~]# ls
anaconda-ks.cfg  apache-tomcat-9.0.46.tar.gz

#解压安装包
[root@node2 ~]# mkdir /usr/local/tomcat
[root@node2 ~]# tar xf apache-tomcat-9.0.46.tar.gz 
[root@nide2 ~]# cp -r apache-tomcat-9.0.46/* /usr/local/tomcat/
[root@node2 ~]# ls /usr/local/tomcat/
bin           conf             lib      logs    README.md      RUNNING.txt  webapps
BUILDING.txt  CONTRIBUTING.md  LICENSE  NOTICE  RELEASE-NOTES  temp         work

开始部署

第一步：安装jenkins

安装和配置jenkins详情可以参考：jenkins安装和界面说明

选择推荐插件安装（这一步需要注意，其它步骤一致）

image

第二步：配置jenkins

1、访问网页

访问192.168.110.14:8080/jenkins

image

2、创建流水线项目

创建任务

image

输入任务名称test，选择流水线

image

3、配置test流水线任务

使用构建化参数定义变量

image

定义文本参数变量

image

  • 项目的名称 Project_name ：ly-simple-tomcat-0.0.1-SNAPSHOT

image

  • Tomcat容器解压的目录 Tomcat_dir ：/usr/local/tomcat/

image

  • 客户机的IP地址 Client_IP ：192.168.110.13

image

编写流水线代码

image

流水线脚本内容

pipeline {
    agent any
    
    stages {
        stage('pull code') {
            steps {
                git '${Git_URL}'
            }
        }

        stage('package') {
            steps {
                sh """
                mvn clean
                mvn package
                """
            }
        }
        
        stage('deploy') {
            steps {
                sh """
                scp target/${Project_name}.war root@${Client_IP}:${Tomcat_dir}webapps/
                ssh root@${Client_IP} '${Tomcat_dir}bin/shutdown.sh && ${Tomcat_dir}bin/startup.sh'
                """
            }
        }
        
    }
}

4、构建任务

使用参数构建

image

构建过程

image

构建成功

image

第三步：验证

在node2主机上查看运行情况

//node2
[root@node2 ~]# ss -antl
State     Recv-Q    Send-Q            Local Address:Port       Peer Address:Port    
LISTEN    0         128                     0.0.0.0:22              0.0.0.0:*       
LISTEN    0         1            [::ffff:127.0.0.1]:8005                  *:*       
LISTEN    0         100                           *:8080                  *:*       
LISTEN    0         128                        [::]:22                 [::]:*       

//项目文件
[root@node2 ~]# ls /usr/local/tomcat/webapps/
docs          ly-simple-tomcat-0.0.1-SNAPSHOT      ROOT
examples      ly-simple-tomcat-0.0.1-SNAPSHOT.war
host-manager  manager

大功告成，以上就是一个简单的项目发布流程！！！
