使用docker安装jenkins,然后使用jenkins本地发版和远程发版
1、安装docker
1.安装必要的一些系统工具
sudo yum install docker-ce
2.添加软件源信息
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
3.更新yum索引列表并安装Docker引擎
sudo yum makecache fast
4.yum索引列表没有更新可以直接使用yum makecache(若有报错请翻阅第四部分第二条)
docker-ce:社区版的,docker-ee:企业版的
sudo yum install docker-ce
5.安装过程中会提示确认,输入y以确认
6.开启Docker服务
sudo service docker start
或者 systemctl start docker
7.测试是否安装成功
docker version
2、使用安装jenkins
1. 启动docker的jenkins,步骤1和2使用的是命令行方式,步骤3和步骤4是使用的 Dockerfile加ssh脚本方式
1.拉取镜像
docker pull jenkins/jenkins
2.docker run命令运行jenkins容器
# -p端口映射,-v挂载工作目录 --env 指定一些配置 如--prefix是我要使用nginx代理,所以给jenkins加上前缀
# 第二个-v是挂载的maven,需要先在官网下载一个maven,把配置文件改为阿里云镜像,服务器上的路径是/datadrive/software/docker-config/jenkins/maven,jenkins容器内对应的是/home/maven路径
# 挂载jenkins_home时可能在启动时会报Permission denied,可以进入文件目录,使用chmod 777 /datadrive/software/docker-config/jenkins/jenkins_home:/var/jenkins_home 给这个文件夹权限
# git和apache-maven-3.6.3可以到jenkins的全局工具中选择自动安装,当然jdk也可以,这样就可以不挂载了
docker run --name jenkins \
-p 8003:8080 -p 50000:50000 \
-v /datadrive/software/docker-config/jenkins/jenkins_home:/var/jenkins_home \
-v /datadrive/software/apache-maven-3.6.3:/datadrive/software/apache-maven-3.6.3 \
-v /datadrive/software/jdk1.8.0_301:/datadrive/software/jdk1.8.0_301 \
-v /datadrive/software/git:/datadrive/software/git \
-v /datadrive/:/datadrive/ \
-v /run/docker.sock:/var/run/docker.sock \
-v /usr/bin/docker:/usr/bin/docker \
-v "$HOME":/home \
--env JENKINS_OPTS="--prefix=/jenkins -Xmx512m" \
-d jenkins/jenkins
3.使用Dockerfile制作镜像
FROM jenkins/jenkins:latest
# 更改用户为root
USER root
创建Dockerfile touch Dockerfile
给Dockerfile赋权限 chmod 1777 Dockerfile
4.使用ssh脚本制作构建镜像和启动容器
#!/bin/bash -il
cd /datadrive/software/docker-config/jenkins
docker rm -f ai-statistics-service
docker rmi -f jenkins/jenkins:latest
docker build -t jenkins/jenkins:latest -f Dockerfile .
docker run --name jenkins \
-p 8003:8080 -p 50000:50000 \
-v /datadrive/software/docker-config/jenkins/jenkins_home:/var/jenkins_home \
-v /datadrive/software/apache-maven-3.6.3:/datadrive/software/apache-maven-3.6.3 \
-v /datadrive/software/jdk1.8.0_301:/datadrive/software/jdk1.8.0_301 \
-v /datadrive/software/git:/datadrive/software/git \
-v /datadrive/:/datadrive/ \
-v /run/docker.sock:/var/run/docker.sock \
-v /usr/bin/docker:/usr/bin/docker \
-v "$HOME":/home \
--env JENKINS_OPTS="--prefix=/jenkins -Xmx512m" \
-d jenkins/jenkins:latest
创建jenkins脚本文件 touch jenkins.sh
给Dockerfile脚本文件 chmod 1777 jenkins.sh
执行脚本文件 ./jenkins.sh
2. 构建jenkins容器如果出现错误
touch: cannot touch ‘/var/jenkins_home/copy_reference_file.log’: Permission denied
Can not write to /var/jenkins_home/copy_reference_file.log. Wrong volume permissions?
表示容器中的/var/jenkins_home路径对应的宿主机地址/datadrive/software/docker-config/jenkins/jenkins_home:/var/jenkins_home
的权限不足,需要把宿主机的地址权限使用chmod 1777 xxx更改下,再启动容器就可以了
3. 进入jenkins容器内
#jenkins账号登录进入
docker exec -it jenkins bash
#root账号登录进入
docker exec -u 0 -it jenkins bash
whoami docker容器可以查看当前用户是否为root
# 获取密码
cat /var/jenkins_home/secrets/initialAdminPassword
4. 构建流程
1.插件管理中选择Available plugins菜单搜索:Publish Over SSH插件下载
2.全局工具配置
1.如果是自动安装它的安装路径是/datadrive/software/docker-config/jenkins/jenkins_home/tools,注意是docker的映射路径jenkins_home
2.jdk安装,可以使用宿主机的jdk,但是启动docker的时候需要将宿主机的jdk映射到docker中;
3.安装Git installations
4.Maven安装,自动安装路径
3.cd /datadrive/software/docker-config/jenkins/jenkins_home/workspace这个路径是jenkins的存储路径,构建项目存储在这个路径下
4.凭据管理,新增git账号和linux账号的凭据
5.系统管理菜单
6.构建任务
1.新建任务,填写任务名称,选择构建一个自由风格的软件项目
2.配置git
3.选择Build Steps,按照顺序添加下面两个构建步骤
1.调用顶层 Maven 目标
2.执行 shell
7.构建vue前端
1.构建流程
1.插件管理中选择Available plugins菜单搜索:nodejs
2.全局工具配置NodeJS
3.凭据管理,新增git账号
2.构建任务
1.新建任务,填写任务名称,选择构建一个自由风格的软件项目
2.配置git
3.选择源码管理,搜索:Provide Node & npm bin/ folder to PATH菜单勾选上
4.选择Build Steps,执行shell
8. 构建错误
1.git rev-parse --resolve-git-dir /var/jenkins_home/workspace/ai-admin/.git # timeout=10
可以忽略
2.构建项目出现错误:Exception:Auth fail for methods ‘publickey,gssapi-keyex,gssapi-with-mic,password’
chmod 700 /root/.ssh
chmod 600 /root/.ssh/authorized_keys
3.com.jcraft.jsch.JSchException: Session.connect: java.net.SocketTimeoutException: Read timed
timeout延长到100
4.symbol class base64encoder location package sun.misc
到全局工具中把jdk设置为1.8,指定jdk的 JAVA_HOME=/datadrive/software/jdk1.8.0_301,宿主机的映射路径
5.jenkins cp: cannot create regular file xxx Permission denied
使用sudo
6./tmp/jenkins17356870084788890789.sh: line 71: sudo: command not found
找不到sudo命令,需要使用root账号登录容器docker exec -u 0 -it jenkins bash,进行yum下载命令
7.bash: docker: command not found
-v /run/docker.sock:/var/run/docker.sock
-v /usr/bin/docker:/usr/bin/docker
8.dial unix /var/run/docker.sock: connect: permission denied
重启失效:sudo chmod 666 /var/run/docker.sock
9.bash: /usr/bin/docker: Permission denied
sudo chmod 777 /usr/bin/docker
10.Step 1/7 : FROM java:8
manifest for java:8 not found: manifest unknown: manifest unknown
DockerFile中的FROM镜像有问题
11.E: List directory /var/lib/apt/lists/partial is missing. - Acquire (13: Permission denied)
这里是权限报错,在exec进来的时候加上 -u 0 即可:
docker exec -u 0 -it jenkins bash
12.bash: yum: command not found
apt-get update
apt-get install sshpass 安装sshpass命令
13.jenkins执行shell执行完成后无法停止
是因为使用sshpass登录需要执行exit退出指令
14.stderr: fatal: unable to access ‘https://gitee.com/hahaha9/ai-project.git/’:Failed to connect to gitee.com port 443 after 255971 ms: Couldn’t connect to server
git仓库地址Repository URL有误,如果是gitee仓库有时候可以不稳定,到本地拉取提交下项目再试试
15.bash: npm: command not found
使用root账号登录容器:docker exec -u 0 -it jenkins bash
apt-get install npm 安装npm命令
16.scp: local “dist” is not a regular file
scp: failed to upload file dist to /datadrive/mnt/ai/web-admin/dist
解决办法:需要添加一个-r参数表示复制该文件夹下的所有文件和目录,下面是一个示例
sshpass -p ‘pwd’ scp -r -q -o StrictHostKeyChecking=no dist root@x.x.x.x:/web-admin/dist
17.jenkins的git拉取代码问题,stderr: fatal: not in a git directory
直接进入容器执行:git config --global --add safe.directory ‘*’
18.Docker中apt-update遇到Err:1 http://deb.debian.org/debian bookworm InRelease
Couldn’t create temporary file /tmp/apt.conf.8ESGGX for passing config to apt-key的解决方法
进入容器执行:chmod 1777 /tmp
19.apt-get出现Package ‘ping‘ has no installation candidate解决
apt-get install -y inetutils-ping
9.Dockerfile和ssh脚本
1.Dockerfile
# 指定是基于哪个基础镜像

# 挂载点声明
VOLUME /tmp
# 将本地的一个文件或目录,拷贝到容器的文件或目录里,这里注意目录结构,前面的是对应宿主机的目录
