jenkins流水线项目发布流程

 

 

 环境

 

主机	ip地址	安装	环境
node5	192.168.170.134	tomcat，jenkins	centos8
node4	192.168.170.133	tomcat	centos8

 

 

替换源为国内源

 

 

 

 

 

安装插件（如果装不好，可以尝试使用推荐安装）

 

 

 

 安装了pipeline后就有了流水线，创建一个流水线项目

 

 

 

 

 

 

 

 

 

 

 

安装

[root@node5 ~]# yum install -y git
[root@node5 ~]# yum install  -y maven

 

 

拉代码

 

 

 

 

 

拉代码（脚本语法，url地址）

 

 点击立即构建就可以开始工作

 

 

 

 

 

 

 

 

 

 

项目开始工作，绿色代表成功，红色代表失败。

 

 

 

 

 

 

打包，都是绿色的代表成功。

 

 

 

 

 

 

 

 

查看工作日志，点击项目绿色上面的logs

 

 

 

 

发现打包了一个war包在该目录，去终端查看一下

[root@node5 ~]# ls /root/.jenkins/workspace/tomcat_Demo/target/
classes            ly-simple-tomcat-0.0.1-SNAPSHOT      maven-archiver
generated-sources  ly-simple-tomcat-0.0.1-SNAPSHOT.war  maven-status

 

 

给node4做免密认证

[root@node5 ~]#  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:lhBl4RQdlPXcEeTjULgWIkSKc9RE6RzCX0av5G3B4mE root@node5
The key's randomart image is:

[root@node5 ~]# ssh-copy-id  root@192.168.170.133

The authenticity of host '192.168.170.133 (192.168.170.133)' can't be established.
ECDSA key fingerprint is SHA256:jVnkkd9Xi4gyvKGo6MZuf+RYVysQmAcKhtY+kyMT+IU.
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@192.168.170.133's password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'root@192.168.170.133'"
and check to make sure that only the key(s) you wanted were added.
