一、安装docker
1.更新系统
dnf update
# 最后出现这个标识就说明更新系统成功
Complete!
2.添加docker源
dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo
# 最后出现这个标识就说明添加成功
Adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
3.安装docker，并允许卸载已经安装的软件(建议不加，避免出现卸载其他软件所需的依赖，而导致其他软件使用异常)
yum install -y docker-ce --allowerasing
# 最后出现这个标识就说明安装成功
Complete!
4.启动 Docker
systemctl start docker
5.查看 Docker 启动状态
systemctl status docker
active说明docker已经启动。

6.设置 Docker 开机自启
systemctl enable docker
二、安装GitLab
1.查找GitLab
docker search gitlab
2.拉取gitlab镜像
docker pull gitlab/gitlab-ce:latest
如果查找的镜像没有自己想要的，直接使用拉取gitlab/gitlab-ce:latest这个官方最新镜像。
# 看到一下信息，说明镜像拉取成功，也可以通过docker images查看拉取的镜像，如果能看到gitlab/gitlab-ce镜像，说明拉取成功
latest: Pulling from gitlab/gitlab-ce

Status: Downloaded newer image for gitlab/gitlab-ce:latest
docker.io/gitlab/gitlab-ce:latest
3.启动gitlab
注意先使用一下命令创建挂载卷目录：mkdir -p ./software/gitlab/{logs,data,config}，这样就可以不用进入容易查看gitlab的一些目录。
docker run -d \
--hostname gitlab.orkasgb.com \
-p 8443:443 -p 8090:80 -p 8022:22 \
--restart always --name gitlab \
-v /orkasgb/software/gitlab/config:/etc/gitlab \
-v /orkasgb/software/gitlab/log:/var/log/gitlab \
-v /orkasgb/software/gitlab/data:/var/opt/gitlab \
--privileged=true gitlab/gitlab-ce \
参数解释：
-d #后台运行，全称：detach
-p 8443:443 #将容器内部端口向外映射，全称：publish
-p 8090:80 #将容器内80端口映射至宿主机8090端口，这是访问gitlab的端口，全称：publish
-p 8022:22 #将容器内22端口映射至宿主机8022端口，这是访问ssh的端口，全称：publish
–restart always #容器自启动
–name gitlab #设置容器名称为gitlab
-v /orkasgb/software/gitlab/config:/etc/gitlab #将容器/etc/gitlab目录挂载到宿主机/usr/local/gitlab/etc目录下，若宿主机内此目录不存在将会自动创建
-v /orkasgb/software/gitlab/log:/var/log/gitlab #与上面一样
-v /orkasgb/software/gitlab/data:/var/opt/gitlab #与上面一样
–privileged=true #让容器获取宿主机root权限
gitlab/gitlab-ce #镜像的名称，这里也可以写镜像ID
4.查看启动日志
docker logs gitlab
- acme (4.1.6)
# 如果没有明显错误，说明启动正常

10.进入到gitlab容器进行基础信息配置
docker exec -it gitlab bash
10.1 编辑gitlab.rb
cd /etc/gitlab
vi ./gitlab.rb
- 修改
external_url为node-05 - 修改
gitlab_rails['gitlab_ssh_host']为node-05 - 修改
gitlab_rails['gitlab_shell_ssh_port']为8022
10.2 编辑gitlab.yml
cd /opt/gitlab/embedded/service/gitlab-rails/config
vim gitlab.yml
- 修改port为8022
- 修改url为node-05
10.3.重置账户密码信息，在容器内部，使用gitlab-rails console -e production重置密码。
- 链接数据库：
gitlab-rails console -e production - 获取用户：
user = User.where(id:1).first - 修改用户账号：
user.username = 'gitlab' - 修改用户密码：
user.password = 'gitlab123' - 保存用户：
user.save!
11.保存配置后，重启
重启配置：gitlab-ctl reconfigure或者直接重启gitlab：gitlab-ctl restart gitlab
12.重启后，就可以使用http://ip:8090访问gitlab，账户为gitlab
13.点击登录用户的头像，设置为中文界面，在配置gitlab界面，启用允许从其他项目导入功能。
