Jenkins environment construction

Jenkins environment installation

I used war installation before, the installation is relatively simple, that is, the corresponding plug-in of jenkins cannot be downloaded, and later found out that it is a version problem, using docker-compose installation, jenkins installation plug-in is easy to install

1. Install jdk

• decompress jdk

• Configure environment variables

  #set java environment
  JAVA_HOME=/usr/local/jdk1.8.0_281
  PATH=$JAVA_HOME/bin:$PATH
  export JAVA_HOME PATH
  

2. Install maven

Download maven linux version

https://dlcdn.apache.org/maven/maven-3/3.9.3/binaries/

Upload to soft under opt under linux

Unzip to /usr/local/

tar -xvf apache-maven-3.6.3-bin.tar.gz -C /usr/local

Configure maven's warehouse location

<localRepository>/opt/maven/repo</localRepository>

Configure Ali Mirror

    <mirror>
		<id>aliyunmaven</id>
		<mirrorOf>*</mirrorOf>
		<name>阿里云公共仓库</name>
		<url>https://maven.aliyun.com/repository/public</url>
	</mirror>

Maven configuration environment variables

Configure environment variables: configure maven environment variables under the /etc/profile file

Refresh after configuration

source /etc/profile

JAVA_HOME=/usr/local/jdk1.8.0_281
MAVEN_HOME=/usr/local/apache-maven-3.6.3
PATH=$JAVA_HOME/bin:$PATH:$MAVEN_HOME/bin
export JAVA_HOME PATH MAVEN_HOME

3. Install git

yum -y install git # 安装
git version        # 安装是否成功 

4. Install docker

# 1、yum 包更新到最新（时间比较久，大概5分钟左右）
sudo yum update

# 2、作用：安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

# 3、 设置yum源
# 使用ustc的
sudo yum-config-manager --add-repo http://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo

# 4、 安装docker；出现输入的界面都按 y（时间比较久，大概30分钟左右,ce表示社区版 ee表示企业版）
sudo yum install -y docker-ce

# 5、 查看docker版本
docker -v

5. Install docker-compose

Install

sudo curl -L "https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

Installation process:

chmod +x /usr/local/bin/docker-compose set permissions, open

Check if the installation was successful:

6. Install jenkins

Install based on docker-compose

version: "3"
services:
  jenkins:
    image: "jenkins/jenkins:2.396-jdk11"
    user: root 
    privileged: true
    restart: always
    container_name: jenkins
    ports:
      - 8080:8080
      - 50000:50000
    volumes:
      - /opt/jenkins/jenkins_home:/var/jenkins_home
      - /usr/local/apache-maven-3.6.3://usr/local/apache-maven-3.6.3  # 配置maven
      # 让容器使用宿主的docker
      - /var/run/docker.sock:/var/run/docker.sock
      - /usr/bin/docker:/usr/bin/docker
      - /etc/docker:/etc/docker
    environment:
      - TZ=Asia/Shanghai

7. Start jenkins

8. Install the plug-in

1. Obtain and enter the admin account password

Enter the container and get the password

docker exec -it jenkins bash

cat /var/jenkins_home/secrets/initialAdminPassword

Different versions may be in different locations: xxx

2. Install the recommended plug-ins

Notice:

There are version and plug-in problems, and the installation cannot be successful

3. Add an administrator account and enter the Jenkins background

Create one: account: admin password 123456

9. The homepage of jenkins:
