一、jenkins介绍

Jenkins是一个开源软件项目，是基于Java开发的一种持续集成工具，用于监控持续重复的工作，旨在提供一个开放易用的软件平台，使软件项目可以进行持续集成。

二、jenkins功能

• 一个自动构建过程，包括自动编译、分发、部署和测试等。
• 一个代码存储库，即需要版本控制软件来保障代码的可维护性，同时作为构建过程的素材库。
• 一个持续集成服务器。

  三、检查本地docker状态

  ```
  [root@node ~]# systemctl status docker

docker.io/jenkins/jenkins:latest

# 五、部署jenkins
## 1.创建数据目录

[root@node ~]# mkdir -p /data/jenkins/data
[root@node ~]# chmod -R 777 /data/jenkins/data/
[root@node ~]#

## 2.创建jenkins容器

[root@node jenkins]# docker run -d --name jenkins --restart always -p 8774:8080 -p 50100:50000 -v /data/jenkins/data/:/var/jenkins_home -v /etc/localtime:/etc/localtime jenkins/jenkins
b44ef8c88d09e5eebb996c91691101fb534859aa3185bdc8bf3c0a8ebf443cbf

## 3.查看jenkins容器状态

[root@node jenkins]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b44ef8c88d09 jenkins/jenkins "/sbin/tini -- /usr/…" 2 minutes ago Up 2 minutes 0.0.0.0:8774->8080/tcp, :::8774->8080/tcp, 0.0.0.0:50100->50000/tcp, :::50100->50000/tcp jenkins

# 六、配置jenkins镜像加速

[root@node data]# cat hudson.model.UpdateCenter.xml

default
https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

# 七、访问jenkins

[root@node data]# cat secrets/initialAdminPassword
9e501f00a41f472292367def3724d81b
[root@node data]#

```

八、jenkins初始化及安装插件

九、创建管理员账号

十、进入jenkins首页
