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
-rw-r--r--. 1 root root 1869 Apr 14 15:30 config.xml #找到这个文件 -rw-r--r--. 1 root root 156 Apr 14 05:18 hudson.model.UpdateCenter.xml -rw-r--r--. 1 root root 1230 Apr 14 15:20 hudson.plugins.emailext.ExtendedEmailPublisher.xml -rw-r--r--. 1 root root 370 Apr 14 05:25 hudson.plugins.git.GitTool.xml -rw-------. 1 root root 1712 Apr 14 05:18 identity.key.enc -rw-r--r--. 1 root root 94 Apr 14 15:30 jenkins.CLI.xml -rw-r--r--. 1 root root 7 Apr 14 05:43 jenkins.install.InstallUtil.lastExecVersion -rw-r--r--. 1 root root 7 Apr 14 05:43 jenkins.install.UpgradeWizard.state -rw-r--r--. 1 root root 138 Apr 14 15:30 jenkins.model.DownloadSettings.xml -rw-r--r--. 1 root root 184 Apr 14 05:43 jenkins.model.JenkinsLocationConfiguration.xml -rw-r--r--. 1 root root 357 Apr 14 15:30 jenkins.security.apitoken.ApiTokenPropertyConfiguration.xml -rw-r--r--. 1 root root 169 Apr 14 15:30 jenkins.security.QueueItemAuthenticatorConfiguration.xml -rw-r--r--. 1 root root 162 Apr 14 15:30 jenkins.security.UpdateSiteWarningsConfiguration.xml -rw-r--r--. 1 root root 171 Apr 14 05:18 jenkins.telemetry.Correlator.xml drwxr-xr-x. 2 root root 6 Apr 14 05:18 jobs drwxr-xr-x. 4 root root 33 Apr 14 15:34 logs -rw-r--r--. 1 root root 907 Apr 14 05:18 nodeMonitors.xml drwxr-xr-x. 3 root root 20 Apr 14 15:34 nodes drwxr-xr-x. 76 root root 8192 Apr 14 05:29 plugins -rw-r--r--. 1 root root 64 Apr 14 05:18 secret.key -rw-r--r--. 1 root root 0 Apr 14 05:18 secret.key.not-so-secret drwx------. 4 root root 4096 Apr 14 15:35 secrets drwxr-xr-x. 2 root root 182 Apr 14 05:23 updates drwxr-xr-x. 2 root root 24 Apr 14 05:18 userContent drwxr-xr-x. 3 root root 56 Apr 14 05:18 users drwxr-xr-x. 11 root root 4096 Apr 14 05:17 war drwxr-xr-x. 2 root root 6 Apr 14 05:25 workflow-libs
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> <disabledAdministrativeMonitors/> <version>2.164.2</version> <installStateName>RUNNING</installStateName> <numExecutors>2</numExecutors> <mode>NORMAL</mode> <useSecurity>true</useSecurity> #删除 <authorizationStrategy class="hudson.security.FullControlOnceLoggedInAuthorizationStrategy"> <denyAnonymousReadAccess>true</denyAnonymousReadAccess> </authorizationStrategy> <securityRealm class="hudson.security.HudsonPrivateSecurityRealm"> <disableSignup>true</disableSignup> <enableCaptcha>false</enableCaptcha> </securityRealm> <disableRememberMe>false</disableRememberMe> <projectNamingStrategy class="jenkins.model.ProjectNamingStrategy$DefaultProjectNamingStrategy"/> <workspaceDir>${JENKINS_HOME}/workspace/${ITEM_FULL_NAME}</workspaceDir> <buildsDir>${ITEM_ROOTDIR}/builds</buildsDir> <markupFormatter class="hudson.markup.EscapedMarkupFormatter"/> <jdks/> <viewsTabBar class="hudson.views.DefaultViewsTabBar"/> <myViewsTabBar class="hudson.views.DefaultMyViewsTabBar"/> <clouds/> <scmCheckoutRetryCount>0</scmCheckoutRetryCount> <views> <hudson.model.AllView> <owner class="hudson" reference="../../.."/> <name>all</name> <filterExecutors>false</filterExecutors> <filterQueue>false</filterQueue> <properties class="hudson.model.View$PropertyList"/> </hudson.model.AllView> </views> <primaryView>all</primaryView> <slaveAgentPort>8181</slaveAgentPort> <enabledAgentProtocols> <string>JNLP-connect</string> <string>JNLP2-connect</string> <string>JNLP3-connect</string> </enabledAgentProtocols> <label></label> <crumbIssuer class="hudson.security.csrf.DefaultCrumbIssuer"> <excludeClientIPFromCrumb>false</excludeClientIPFromCrumb> </crumbIssuer> <nodeProperties/> <globalNodeProperties/> </hudson>
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
