一、系统版本

# cat /etc/anolis-release 
Anolis OS release 8.9

二、安装

# dnf install -y epel-release

# wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo

# rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

三、安装jdk node

下载：Java Archive Downloads - Java SE 21

# tar -zxf jdk-21.0.5_linux-x64_bin.tar.gz -C /usr/local/

下载：Index of /dist/v20.13.1/

# tar -xf node-v20.13.1-linux-x64.tar.xz -C /usr/local/

# vi /etc/profile

export JAVA_HOME=/usr/local/jdk-21.0.5

export NODE_HOME=/usr/local/node-v20.13.1-linux-x64
export PATH=${MAVEN_HOME}/bin:$JAVA_HOME/bin:${NODE_HOME}/bin:${PATH}

# source /etc/profile

# java --version
java 21.0.5 2024-10-15 LTS
Java(TM) SE Runtime Environment (build 21.0.5+9-LTS-239)
Java HotSpot(TM) 64-Bit Server VM (build 21.0.5+9-LTS-239, mixed mode, sharing)

# node -v
v20.13.1
[root@jekins-anolis-2-100 local]# npm -v
10.5.2

# npm config set registry http://registry.npmmirror.com

# npm install -g pnpm

# pnpm -v
10.3.0

四、安装jenkins

# dnf install jenkins -y

三、启动

# vi /usr/lib/systemd/system/jenkins.service

Environment="JAVA_HOME=/usr/local/jdk-21.0.5"

# systemctl daemon-reload

# systemctl daemon-reload
# systemctl start jenkins

# systemctl enable jenkins

四、配置

修改密码：

点击继续使用admin账户后的密码，如果忘记修改密码退出后，按下面操作：

# cat /var/lib/jenkins/secrets/initialAdminPassword

五、安装插件

语言：

六、配置

6.1 nodejs配置

6.2 git配置

七、kubernetes配置

7.1 账户配置

7.2 clouds配置

八、jenkins使用docker问题解决

8.1 提示docker：permission denied

# cd /var/run/

# ls -lh docker.sock

srw-rw----  1 root           docker            0 2月  12 11:39 docker.sock

# chmod o+rw docker.sock 
# ls -lh docker.sock 
srw-rw-rw- 1 root docker 0 2月  12 11:39 docker.sock

8.2  denied: requested access to the resource is denied

# docker login 192.168.x.x

会在宿主目录生成下面文件：

# ls .docker/
config.json

拷贝到/var/lib/jenkins下，并修改权限：

# cp -r .docker /var/lib/jenkins/

# chown -R jenkins:jenkins /var/lib/jenkins/.docker
# ls -lh /var/lib/jenkins/.docker
-rw------- 1 jenkins jenkins  80 2月  12 14:14 config.json

九、jenkins配置k8s的managed files

十、测试代码

def gitlab_auth="20968eb7-xxxx-xxxx-xxxx-xxxxxxxxxx"
def gitlab_url="http://git.kyc.com/20220712dev/platform-crm.git"
def k8s_auth = "1b56a2fa-7117-xxxx-xxxx-xxxxxxxxxxxx"
pipeline {
  agent any
  environment {
      IMAGE_BUILD="${BUILD_ID}"
      JOB_NAME="${env.JOB_NAME}"
  }
  parameters {
      choice (choices: ['master'], description: '指定配置文件',name: 'config')
  }
  stages {
      stage('拉取代码'){
          steps {checkout([$class: 'GitSCM', branches: [[name: '*/master']], extensions: [], userRemoteConfigs: [[credentialsId: "${gitlab_auth}", url: "${gitlab_url}"]]])
          }
      }
      stage('daima代码编译'){
          steps {
          sh """
          cd ${JOB_NAME}
          echo "代码编译"
          source /etc/profile
          
          node --version
          npm config set prefix '~/.npm-global'
          npm config set registry https://registry.npmmirror.com
          npm install -g pnpm
          pnpm install
          npm run build
          cd dist/
          tar -czf ../dist.tar ./*
          """
          }
      }
      stage('Dockerfile'){
            steps{
                sh '''

                cat > Dockerfile <<EOF

                '''

        }
        stage('制作上传镜像'){
            steps{
                sh '''
                cd ${JOB_NAME}
                docker build -t 192.168.2.51/crm/${JOB_NAME}:${IMAGE_BUILD} .
                docker push 192.168.2.51/crm/${JOB_NAME}:${IMAGE_BUILD}
                docker rmi 192.168.2.51/crm/${JOB_NAME}:${IMAGE_BUILD}
                '''
            }
        }
        stage('远程清理'){
            steps{
                sh '''
                cd ${JOB_NAME}
                rm -rf dist.tar
                '''
            }
        }
        stage('yaml'){
            steps{
                sh '''
                cat > /var/lib/jenkins/workspace/${JOB_NAME}/${JOB_NAME}/${JOB_NAME}.yaml <<EOF

--kubeconfig=../admin.kubeconfig

这个需要根据实际目录去写：
