基于docker安装jenkins+gitlab+harbor

1. 安装Docker环境

复制代码

#!/bin/bash
# Docker安装脚本

set -e

echo"=== 开始安装Docker ==="

# 卸载旧版本
sudo yum remove -y docker docker-client docker-client-latest \
    docker-common docker-latest docker-latest-logrotate \
    docker-logrotate docker-engine

# 安装依赖
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

# 添加Docker仓库
sudo yum-config-manager --add-repo \
    https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

# 安装Docker
sudo yum install -y docker-ce docker-ce-cli containerd.io

# 配置Docker镜像加速和日志
sudomkdir -p /etc/docker
sudotee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": [
"https://mirror.ccs.tencentyun.com",
"https://registry.docker-cn.com"
  ],
"log-driver": "json-file",
"log-opts": {
"max-size": "100m",
"max-file": "3"
  },
"storage-driver": "overlay2",
"exec-opts": ["native.cgroupdriver=systemd"]
}
EOF

# 启动Docker
sudo systemctl daemon-reload
sudo systemctl enable docker
sudo systemctl start docker

# 验证安装
docker --version
docker info

echo"=== Docker安装完成 ==="

2.部署GitLab代码仓库

复制代码

#!/bin/bash
# GitLab安装脚本

set -e

GITLAB_HOME="/data/gitlab"
GITLAB_HOSTNAME="reg.cx.test.com"

echo"=== 开始安装GitLab ==="

# 创建数据目录
sudomkdir -p ${GITLAB_HOME}/{config,logs,data}

# 运行GitLab容器
docker run -d \
  --hostname ${GITLAB_HOSTNAME} \
  --name gitlab \
  --restart always \
  --publish 443:443 \
  --publish 80:80 \
  --publish 22:22 \
  --volume ${GITLAB_HOME}/config:/etc/gitlab \
  --volume ${GITLAB_HOME}/logs:/var/log/gitlab \
  --volume ${GITLAB_HOME}/data:/var/opt/gitlab \
  --shm-size 256m \
  gitlab/gitlab-ce:latest

echo"=== GitLab正在启动,需要3-5分钟 ==="
echo"等待GitLab启动..."

# 等待GitLab启动
for i in {1..30}; do
if docker logs gitlab 2>&1 | grep -q "gitlab Reconfigured"; then
echo"GitLab启动成功!"
break
fi
echo"等待中... ($i/30)"
sleep 10
done

# 获取初始密码
echo""
echo"=== GitLab初始管理员密码 ==="
docker exec gitlab cat /etc/gitlab/initial_root_password | grep Password:

echo""
echo"访问地址: http://${GITLAB_HOSTNAME}"
echo"管理员账号: root"
echo"请保存上面的初始密码,24小时后将自动删除"

3.部署Harbor镜像仓库

复制代码

#!/bin/bash
# Harbor安装脚本

set -e

HARBOR_VERSION="v2.11.0"
HARBOR_DOMAIN="harbor.company.com"# 修改为你的域名
HARBOR_ADMIN_PASSWORD="Harbor123456"# 修改管理员密码

echo"=== 开始安装Harbor ==="

# 安装docker-compose
sudo curl -L "https://github.com/docker/compose/releases/download/v2.20.0/docker-compose-$(uname -s)-$(uname -m)" \
  -o /usr/local/bin/docker-compose
sudochmod +x /usr/local/bin/docker-compose

# 下载Harbor
cd /opt
wget https://github.com/goharbor/harbor/releases/download/${HARBOR_VERSION}/harbor-offline-installer-${HARBOR_VERSION}.tgz
tar xzvf harbor-offline-installer-${HARBOR_VERSION}.tgz
cd harbor

# 配置Harbor
cp harbor.yml.tmpl harbor.yml
sed -i "s/hostname: reg.mydomain.com/hostname: ${HARBOR_DOMAIN}/g" harbor.yml
sed -i "s/harbor_admin_password: Harbor12345/harbor_admin_password: ${HARBOR_ADMIN_PASSWORD}/g" harbor.yml

# 禁用HTTPS(测试环境,生产建议启用)
sed -i '/^https:/,+8 s/^/#/' harbor.yml

# 安装Harbor
sudo ./install.sh

echo"=== Harbor安装完成 ==="
echo"访问地址: http://${HARBOR_DOMAIN}"
echo"管理员账号: admin"
echo"管理员密码: ${HARBOR_ADMIN_PASSWORD}"

4.部署Jenkins CI/CD引擎

复制代码

#!/bin/bash
# Jenkins安装脚本

set -e

JENKINS_HOME="/data/jenkins"

echo"=== 开始安装Jenkins ==="

# 创建数据目录
sudomkdir -p ${JENKINS_HOME}
sudochown -R 1000:1000 ${JENKINS_HOME}

# 运行Jenkins容器
docker run -d \
  --name jenkins \
  --restart always \
  --user root \
  -p 8080:8080 \
  -p 50000:50000 \
  -v ${JENKINS_HOME}:/var/jenkins_home \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /usr/bin/docker:/usr/bin/docker \
  jenkins/jenkins:lts

echo"=== 等待Jenkins启动(约2分钟) ==="
sleep 120

# 获取初始密码
echo""
echo"=== Jenkins初始管理员密码 ==="
docker exec jenkins cat /var/jenkins_home/secrets/initialAdminPassword

echo""
echo"访问地址: http://YOUR_IP:8080"
echo"请使用上面的密码登录并完成初始化配置"
