CI/CD:持续集成/持续部署

1. 安装docker、docker-compose

# 安装Docker
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
yum makecache fast
yum -y install docker-ce
systemctl enable docker --now

安装Docker Compose

下载地址：GitHub - docker/compose: Define and run multi-container applications with Docker

# 安装Docker Compose
wget https://github.com/docker/compose/releases/download/v2.26.0/docker-compose-linux-x86_64
mv docker-compose-linux-x86_64 
chmod +x /usr/local/bin/docker-compose

2. GitLab部署

2.1. gitlab部署

GitLab的部署方式有很多，这里使用docker来部署GitLab，docker-compose.yml文件位置如下：

version: '3.6'
services:
  gitlab:
    image: gitlab/gitlab-ce:latest
    container_name: gitlab
    restart: always
    environment:
      GITLAB_OMNIBUS_CONFIG: |
        external_url 'http://10.10.10.11:80'
        gitlab_rails['gitlab_shell_ssh_prot'] = 22
    ports:
      - '80:80'
      - '443:443'
      - '2224:22'
    volumes:
      - './config:/etc/gitlab'
      - './logs:/var/log/gitlab'
      - './data:/var/opt/gitlab'

启动gitlab

docker-compose -f /home/gitlab/docker-compose.yml up -d

# 查看日志输出完毕即可通过浏览器访问
docker logs -f gitlab

# 查看密码
docker exec -it gitlab bash
cat /etc/gitlab/initial_root_password

2.2. 修改密码

修改密码:点击头像选择Preferences->Password->Save changes

2.3. 修改语言

修改语言:点击头像选择Preferences->Localization->Language选项中选择Chinese->Save changes

# 下载Harbor安装程序
wget https://github.com/goharbor/harbor/releases/download/v2.10.2/harbor-offline-installer-v2.10.2.tgz
tar -zxvf harbor-offline-installer-v2.10.2.tgz
mv harbor /usr/local

# 修改配置文件
cd /usr/local/harbor/
cp harbor.yml.tmpl harbor.yml
vim harbor.yml

# 开始安装
./prepare
./install.sh
# Harbor安装完成之后通过docker-compose来管理
docker-compose ps

4. Jenkins部署

4.1. jenkins部署

Jenkins的dokcer-compose文件如下：

version: "3.6"
services:
  jenkins:
    image: jenkins/jenkins:2.414.3-lts
    container_name: jenkins
    restart: always
    privileged: true
    user: root
    environment:
      TZ: 'Asia/Shanghai'
    ports:
      - 8080:8080
      - 50000:50000
    volumes:
      - ./data:/var/jenkins_home
      - /var/run/docker.sock:/var/run/docker.sock
      - /usr/bin/docker:/usr/bin/docker
      - /etc/docker/daemon.json:/etc/docker/daemon.json

启动jenkins

docker-compose -f /home/jenkins/docker-compose.yml up -d

# 查看密码
docker logs -f jenkins

4.2. 修改国内插件下载地址：

# 修改插件下载地址
cd /home/jenkins/data/updates
sed -i 's/https:\/\/updates.jenkins.io\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json #适用于新版本。
sudo sed -i 's/https:\/\/www.google.com/https:\/\/www.baidu.com/g' default.json
docker-compose -f /home/jenkins/docker-compose.yml  restart

4.3. 插件安装

插件安装：点击Manage Jenkins->Plugins->Available plugins

4.4. 配置全局环境JDK和Maven

JDK下载地址：Java Archive Downloads - Java SE 8u211 and later

Maven下载地址：Maven – Welcome to Apache Maven

将下载的安装包上传到服务器。

tar -zxvf jdk-8u381-linux-x64.tar.gz -C 
tar -zxvf apache-maven-3.9.6-bin.tar.gz 
mv jdk1.8.0_381/ /home/jenkins/data/jdk
mv apache-maven-3.9.6 /home/jenkins/data/maven

# 配置maven私服地址
cd /usr/local/maven
vim conf/settings.xml
# 在mirrors节点下面添加子节点
