4. Docker安装方式

Docker是部署Jenkins最简单的方式。from:www.itpux.com

# 拉取Jenkins Docker镜像
$ docker pull jenkins/jenkins:lts

# 输出示例如下：
lts: Pulling from jenkins/jenkins
Digest: sha256:abc123def456…
Status: Downloaded newer image for jenkins/jenkins:lts
docker.io/jenkins/jenkins:lts

# 创建数据目录
$ mkdir -p /fgeudb/jenkins/home

# 启动Jenkins容器
$ docker run -d –name jenkins \
-p 8080:8080 \
-p 50000:50000 \
-v /fgeudb/jenkins/home:/var/jenkins_home \
-e JAVA_OPTS=”-Xmx2g -Xms1g” \
jenkins/jenkins:lts

# 输出示例如下：
abc123def456789…

# 查看容器状态
$ docker ps

# 输出示例如下：
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
abc123def456 jenkins/jenkins:lts “/usr/local/bin/jenk…” 5 seconds ago Up 4 seconds 0.0.0.0:8080->8080/tcp, 0.0.0.0:50000->50000/tcp jenkins

# 查看初始密码
$ docker logs jenkins | grep -A 2 “initialAdminPassword”

# 输出示例如下：
*************************************************************
*************************************************************
*************************************************************

Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:

abc123def456789012345678901234567890

This may also be found at: /var/jenkins_home/secrets/initialAdminPassword

风哥提示：Jenkins默认使用8080端口，首次访问需要输入初始管理员密码。密码可以在日志中找到，也可以在容器内的/var/jenkins_home/secrets/initialAdminPassword文件中查看。

5. 安装介质说明

6. 系统配置方法

Jenkins安装后需要进行基本配置，以下是常用配置方法。更多学习教程公众号风哥教程itpux_com

配置文件说明

# 编辑配置文件

插件安装

# 通过CLI安装插件
$ java -jar jenkins-cli.jar -s http://localhost:8080/ -auth admin:password install-plugin git

# 输出示例如下：

# 重启Jenkins
$ java -jar jenkins-cli.jar -s http://localhost:8080/ -auth admin:password safe-restart

# 输出示例如下：

Jenkins is fully up and running

7. 生产环境建议

在生产环境中使用Jenkins时，需要考虑以下因素：

性能优化配置

# 配置JVM参数
# vi /etc/sysconfig/jenkins

JENKINS_JAVA_OPTIONS=”-Djava.awt.headless=true \
-Xmx4g -Xms2g \
-XX:+UseG1GC \
-XX:MaxGCPauseMillis=200 \
-XX:+HeapDumpOnOutOfMemoryError \
-XX:HeapDumpPath=/fgeudb/jenkins/logs/heapdump.hprof \
-Djenkins.install.runSetupWizard=false \
-Dhudson.slaves.WorkspaceList=- \
-Djava.io.tmpdir=/fgeudb/jenkins/tmp”

# 配置工作目录
# mkdir -p /fgeudb/jenkins/{workspace,logs,tmp}
# chown -R jenkins:jenkins /fgeudb/jenkins

# 配置日志轮转
# vi /etc/logrotate.d/jenkins

/fgeudb/jenkins/logs/*.log {
daily
rotate 30
compress
missingok
notifempty
copytruncate
}

# 配置备份
# vi /etc/cron.daily/jenkins-backup

#!/bin/bash
BACKUP_DIR=/fgeudb/backup/jenkins
DATE=$(date +%Y%m%d)
tar -czf $BACKUP_DIR/jenkins-$DATE.tar.gz /fgeudb/jenkins
find $BACKUP_DIR -name “jenkins-*.tar.gz” -mtime +7 -delete

# chmod +x /etc/cron.daily/jenkins-backup

生产环境建议：Jenkins适合CI/CD场景，建议配置足够的内存和磁盘空间、定期备份JENKINS_HOME目录、配置合理的构建并发数、使用Agent节点分担构建压力、监控Jenkins运行状态、配置安全策略。

8. Pipeline流水线配置

Jenkins Pipeline是Jenkins的核心功能，以下是常用配置：

Declarative Pipeline示例

# 创建Jenkinsfile
# vi Jenkinsfile

pipeline {
agent any

environment {
JAVA_HOME = ‘/usr/lib/jvm/java-17-openjdk’
MAVEN_HOME = ‘/usr/local/maven’
PATH = “${env.JAVA_HOME}/bin:${env.MAVEN_HOME}/bin:${env.PATH}”
}

stages {
stage(‘Checkout’) {
steps {
echo ‘Checking out code…’
git branch: ‘main’, url: ‘https://github.com/fgedu/app.git’
}
}

stage(‘Build’) {
steps {
echo ‘Building application…’
sh ‘mvn clean package -DskipTests’
}
}

stage(‘Test’) {
steps {
echo ‘Running tests…’
sh ‘mvn test’
}
post {
always {
junit ‘**/target/surefire-reports/*.xml’
}
}
}

stage(‘Deploy’) {
when {
branch ‘main’
}
steps {
echo ‘Deploying application…’
sh ‘scp target/app.jar user@192.168.1.51:/fgeudb/app/’
sh ‘ssh user@192.168.1.51 “systemctl restart app”‘
}
}
}

post {
success {
echo ‘Build succeeded!’
emailext subject: ‘Build Success: ${JOB_NAME} #${BUILD_NUMBER}’,
body: ‘Build succeeded. Check console output at ${BUILD_URL}’,
to: ‘admin@fgedu.net.cn’
}
failure {
echo ‘Build failed!’
emailext subject: ‘Build Failed: ${JOB_NAME} #${BUILD_NUMBER}’,
body: ‘Build failed. Check console output at ${BUILD_URL}’,
to: ‘admin@fgedu.net.cn’
}
}
}

多分支Pipeline配置

# 创建多分支Pipeline Job
# 在Jenkins界面中：
# 1. 新建任务 -> Multibranch Pipeline
# 2. 配置Branch Sources -> Git
# 3. 设置Repository URL
# 4. 设置Credentials
# 5. 设置Branch Filter（如：*/main, */develop, */feature/*）

# Pipeline触发配置
# vi Jenkinsfile

pipeline {
agent any

triggers {
cron(‘H/15 * * * *’)
pollSCM(‘H/5 * * * *’)
githubPush()
}

stages {
stage(‘Build’) {
steps {
sh ‘mvn clean package’
}
}
}
}

风哥提示：Jenkins是CI/CD领域的首选工具，Pipeline是Jenkins的核心功能。建议使用Declarative Pipeline语法，代码更清晰易读。配合Git、Docker、Kubernetes等工具，可以构建完整的DevOps流水线。
