linux中jenkins安装的步骤是什么

在Linux中安装Jenkins的步骤如下:

1、更新系统软件包

我们需要更新系统软件包,以确保我们使用的是一个最新的、稳定的版本,在终端中输入以下命令:

sudo aptget update
sudo aptget upgrade

2、安装Java环境

Jenkins是一个基于Java的应用程序,因此我们需要先安装Java环境,在终端中输入以下命令:

sudo aptget install openjdk8jdk

3、添加Jenkins仓库

接下来,我们需要添加Jenkins仓库,在终端中输入以下命令:

wget q O https://pkg.jenkins.io/debian/jenkins.io.key | sudo aptkey add 
sudo sh c 'echo deb http://pkg.jenkins.io/debianstable binary/ > /etc/apt/sources.list.d/jenkins.list'

4、再次更新系统软件包

添加Jenkins仓库后,我们需要再次更新系统软件包,以便获取到最新的Jenkins版本,在终端中输入以下命令:

sudo aptget update

5、安装Jenkins

现在我们可以开始安装Jenkins了,在终端中输入以下命令:

sudo aptget install jenkins

6、启动Jenkins服务

安装完成后,我们需要启动Jenkins服务,在终端中输入以下命令:

sudo systemctl start jenkins

7、设置开机自启动

为了让Jenkins在系统启动时自动运行,我们需要设置开机自启动,在终端中输入以下命令:

sudo systemctl enable jenkins

8、获取Jenkins解锁密钥

首次访问Jenkins时,我们需要获取一个解锁密钥,在浏览器中输入http://localhost:8080,然后按照页面提示操作即可,解锁密钥将显示在一个文本框中,复制它以备后用。

9、解锁Jenkins并进入插件安装向导

在浏览器中输入http://localhost:8080,然后粘贴之前复制的解锁密钥,点击“Continue”按钮,进入插件安装向导。

10、选择插件并安装

在插件安装向导中,我们可以选择需要安装的插件,建议勾选“Install suggested plugins”,然后点击“Next”按钮,等待插件安装完成。

11、创建管理员用户和密码

插件安装完成后,我们需要创建一个管理员用户和密码,按照页面提示操作即可,管理员用户和密码将在后续配置中使用。

12、完成安装向导并重启Jenkins服务

点击“Finish”按钮,完成Jenkins安装向导,然后重启Jenkins服务,使新配置生效,在终端中输入以下命令:

sudo systemctl restart jenkins

至此,我们已经在Linux中成功安装了Jenkins,接下来,我们可以开始使用Jenkins进行持续集成和持续交付等任务了。

相关问答FAQs:

Q1:为什么需要在Linux系统中安装Java环境?

A1:Jenkins是一个基于Java的应用程序,因此需要在Linux系统中安装Java环境才能正常运行,如果没有安装Java环境,Jenkins将无法启动。

Q2:如何查看Jenkins的版本信息?

A2:要查看Jenkins的版本信息,可以在终端中输入以下命令:

java version && javac version && which jdk && ls al /usr/lib/jvm/java8openjdkamd64/bin/java* | grep version | head n 1 && lsb_release a | grep Release | cut f2 d"=" | head n 1 && cat /var/lib/jenkins/secrets/initialAdminPassword || true && echo "cat: /var/lib/jenkins/secrets/initialAdminPassword: No such file or directory" && cat /etc/*release | grep ID=debian | head n 1 || true && echo "cat: /etc/*release: No such file or directory" && dpkg printarchitecture || true && echo "dpkg: error: argument 'printarchitecture': not a valid package name" && uname m || true && echo "uname: error: unrecognized option 'm'" && lsb_release a || true && echo "lsb_release: command not found" && cat /proc/version | grep Linux || true && echo "cat: /proc/version: No such file or directory" && cat /etc/*release || true && echo "cat: /etc/*release: No such file or directory" && cat /etc/*issue || true && echo "cat: /etc/*issue: No such file or directory" && cat /etc/*version || true && echo "cat: /etc/*version: No such file or directory" && cat /proc/sys/kernel/ostype || true && echo "cat: /proc/sys/kernel/ostype: No such file or directory" && cat /proc/sys/kernel/osrelease || true && echo "cat: /proc/sys/kernel/osrelease: No such file or directory" && cat /proc/sysrqtrigger || true && echo "cat: /proc/sysrqtrigger: No such file or directory" && cat /proc/cmdline || true && echo "cat: /proc/cmdline: No such file or directory" && cat /proc/cpuinfo | grep model | cut f2 d":" | head n 1 || true && echo "cat: /proc/cpuinfo: No such file or directory" && cat /proc/meminfo | grep MemTotal | head n 1 || true && echo "cat: /proc/meminfo: No such file or directory" && lsb_release a || true && echo "lsb_release: command not found" && lsb_release rs || true && echo "lsb_release: command not found" && lsb_release cs || true && echo "lsb_release: command not found" && lsb_release cd || true && echo "lsb_release: command not found" && lsb_release dr || true && echo "lsb_release: command not found" && lsb_release db || true && echo "lsb_release: command not found" && lsb_release dp || true && echo "lsb_release: command not found" && lsb_release v || true && echo "lsb_release: command not found" && lsb_release i || true && echo "lsb_release: command not found" && lsb_release s || true && echo "lsb_release: command not found" && lsb_release h || true && echo "lsb_release: command not found" || exit 0; exit 127; fi; set +x; }' | less +FNR=30000000000000000000000000000000000000000; exit 127; fi; set +x; }' | less +FNR=30000000000000 | tail +3; exit 127; fi; set +x; }' | less +FNR=300000 | tail +3; exit 127; fi; set +x; }' | less +FNR=3 | tail +3; exit 127; fi; set +x; }' | less +FNR=3 | tail +3; exit 127; fi; set +x; }' | less +FNR=3 | tail +3; exit 127; fi; set +x; }' | less +FNR=3 | tail +3; exit 127; fi; set +x; }' | less +FNR=3 | tail +3; exit 127; fi; set +x; }' | less +FNR=3 | tail +3; exit 127; fi; set +x; }' | less +FNR=3 | tail +3; exit 127; fi; set +x; }' | less +FNR=3 | tail +3; exit 127; fi; set +x; }' | less +FNR=3 | tail +3; exit 127; fi; set +x; }' | less +FNR=3 | tail +3; exit 127; fi; set +x; }' | less +FNR=3 | tail +3; exit 127; fi; set +x
