什么是默认的Jenkins密码？

Question

我正在使用EC2服务器实例.使用以下方法安装Jenkins:

wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -
sudo sh -c 'echo deb http://pkg.jenkins-ci.org/debian binary/ > /etc/apt/sources.list.d/jenkins.list'
sudo apt-get update
sudo apt-get install jenkins

但我需要在Jenkins服务器上安装软件,所以在我的EC2实例中我做了

sudo –s –H –u jenkins

进入jenkins服务器.然后我试着去做

sudo cabal install quickcheck

但它促使我提供jenkins密码.我一直在互联网上搜索4小时,没有什么能帮助我获得jenkins服务器的管理权限.

所以我在shell中使用以下命令构建我的项目:

sudo cabal clean
sudo cabal configure
sudo cabal build
sudo cabal install

这是我得到的错误:

Answer 1

以下是如何解决它:

• 停止詹金斯
• 去编辑 /var/lib/jenkins/config.xml
• 更改<useSecurity>true</useSecurity>为假
• 重启詹金斯: sudo service jenkins restart
• 导航到Jenkins仪表板,转到之前可能使用的"配置安全性"选项.这次,设置安全性与以前相同,但设置为allow anyone to do anything,并允许用户注册.
• 转到www.yoursite.com/securityRealm/addUser并创建用户
• 然后转到allow anyone to do anything你真正希望用户能够做的任何事情.就我而言,它是allow logged in users to do anything.

Answer 2

如果您在ubuntu 14.04中使用apt-get安装,则会在/ var/lib/jenkins/secrets/initialAdminPassword位置找到默认密码.

Answer 3

在安装jenkins之前,创建一个名为jenkins的用户并在那里设置密码.然后在安装jenkins后,您可以使用您创建的密码.

Answer 4

使用在macOS上使用Homebrew的默认Jenkins安装,这将输出admin用户的初始密码:

sudo cat /Users/Shared/Jenkins/Home/secrets/initialAdminPassword

Answer 5

jenkins默认管理员密码记录在ubuntu的日志文件中

日志文件位于/var/log/jenkins/jenkins.log文件夹中

密码将在此之后放置,需要Jenkins初始设置.已创建管理员用户并生成密码.请使用以下密码继续安装:

Answer 6

安装 Jenkins 后，只需运行sudo cat /var/lib/jenkins/secrets/initialAdminPassword.

在詹金斯登录页面：

User: admin Password: the output from the above command

Answer 7

在 ubuntu 19.04 上，默认密码存储在主目录中：

cat ~/.jenkins/secrets/initialAdminPassword

Answer 8

密码出现在 docker run image 生成的日志中，如下例所示。

Jenkins Docker 运行日志

另外，您可以检查目录 /var/jenkins_home/secrets/ 它的文件名是initialAdminPassword

您可以使用

cat /var/jenkins_home/secrets/initialAdminPassword
