DEVOPS技术实践_02:jenkins自动构建项目

一、用户名密码错误

打开jenkins发现用户名密码错误，解决

1.1 找到config.xml文件

[root@jenkins-master ~]# ll -a

drwxr-xr-x. 12 root root  4096 Apr 14 15:30 .jenkins

[root@jenkins-master ~]# cd .jenkins/

[root@jenkins-master .jenkins]# ll

1.2 备份修改文件

[root@jenkins-master .jenkins]# cp config.xml config.xml.bak

[root@jenkins-master .jenkins]# vim config.xml

<?xml version='1.1' encoding='UTF-8'?>
<hudson>

  </crumbIssuer>

1.3 重启jenkins

[root@jenkins-master .jenkins]# ps -ef |grep  jenkins

[root@jenkins-master .jenkins]# kill -9 105823

[root@jenkins-master ~]# cd /usr/local/src/

[root@jenkins-master src]# nohup java -jar /usr/local/src/jenkins.war --httpPort=9000 &

1.4 修改安全配置

进入首页>“系统管理”>全局安全配置>启用安全>Jenkins专有用户数据库>保存，如下图:

 重新点击首页-系统管理-管理用户

 1.5 重新设置密码

 

登陆成功

 二、jenkins自动构建

 2.1 创建一个任务

选择保存后填下面信息

使用git，地址要填准确，同时在jenkins的服务器上要安装git，否则会报错

2.2 构建项目

构建完成，点击立即构建

点击#1，打开控制台，看输出消息

2.3 配置Mzven

选择系统管理>全局工具配置>新增Maven

[root@node5 ~]# echo $M2_HOME

/usr/local/maven/apache-maven-3.6.1

2.4 在重新构建测试
