设置执行权限并启动docker服务
# chmod +x /etc/systemd/system/docker.service
启动服务，并设置开机启动
# systemctl daemon-reload && systemctl start docker && systemctl enable docker.service
验证服务器启动
# systemctl status docker
安装docker-compose
上传docker-compose-linux-x86_64
配置执行权限
# chmod +x docker-compose-linux-x86_64
重命名为docker-compose并移动到/usr/local/bin/目录
# mv docker-compose-linux-x86_64 /usr/local/bin/docker-compose
验证
# docker-compose -v
部署Gitlab
上传镜像
进入镜像目录，加载docker镜像
# cd /data/gitlab/docker-compose/
# docker load -I gitlab16.2.0.tar
修改配置文件
使用docker-compose通过yml配置文件启动容器
gitlab.yml文件内容
version: '3.8'
services:
web:
image: 'gitlab/gitlab-ce:16.2.0-ce.0' # 使用GitLab社区版镜像，也可使用gitlab/gitlab-ee:latest（企业版）
restart: always
user: 'root' # 设置容器中运行的用户为root用户
#hostname: 'gitlab' # 替换成你的GitLab主机名
container_name: 'gitlab'
environment:
GITLAB_OMNIBUS_CONFIG: |
external_url 'http://192.168.200.160' # 替换成你的GitLab访问URL
ports:
- '80:80'
- '443:443'
- '2222:22' # 用于SSH访问
volumes:
- '/data/gitlab/gitlab_home/config:/etc/gitlab'
- '/data/gitlab/gitlab_home/logs:/var/log/gitlab'
- '/data/gitlab/gitlab_home/data:/var/opt/gitlab'
privileged: true
启动容器
# docker-compose -f gitlab.yml up -d
