```
### （2）下载镜像

```bash
docker pull gitlab/gitlab-ce
```
如下：

```bash
[root@iZbp1flzt6x7pxmxfhmxeeZ ~]# docker pull gitlab/gitlab-ce

Status: Downloaded newer image for gitlab/gitlab-ce:latest
docker.io/gitlab/gitlab-ce:latest
[root@iZbp1flzt6x7pxmxfhmxeeZ ~]#
```
##### （3）启动服务

```bash
docker run -d -p 10008:80 -p 10009:443 -p 10010:22 --restart always --name gitlab -v /docker/gitlab/etc/gitlab:/etc/gitlab -v /docker/gitlab/var/log/gitlab:/var/log/gitlab -v /docker/gitlab/var/opt/gitlab:/var/opt/gitlab --privileged=true gitlab/gitlab-ce

```

### （4）修改gitlab.rb文件

```bash
vi /docker/gitlab/etc/gitlab/gitlab.rb
```
修改如下位置：

```bash 
# 如果使用公有云且配置了域名了，可以直接设置为域名，如下
external_url 'http://gitlab.redrose2100.com'
# 如果没有域名，则直接使用宿主机的ip，如下
external_url 'http://172.22.27.162'  
```

```bash
# 同样如果有域名，这里也可以直接使用域名
gitlab_rails['gitlab_ssh_host'] =  'gitlab.redrosee2100.com'
# 同样如果没有域名，则直接使用宿主机的ip地址
gitlab_rails['gitlab_ssh_host'] = '172.22.27.162'
```

```bash
# 端口为启动docker时映射的ssh端口
gitlab_rails['gitlab_shell_ssh_port'] =10010 
```

```bash
# 设置时区为东八区，即北京时间
gitlab_rails['time_zone'] = 'Asia/Shanghai'  
```

### （5）关于邮箱发邮件的配置如下

```bash
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.163.com"   # 邮箱服务器
gitlab_rails['smtp_port'] = 465    # 邮箱服务对应的端口号
gitlab_rails['smtp_user_name'] = "hitredrose@163.com"   # 发件箱的邮箱地址
gitlab_rails['smtp_password'] = "xxxxxxxxxxx"      # 发件箱对应的授权码，注意不是登录密码，是授权码
gitlab_rails['smtp_domain'] = "163.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true
gitlab_rails['gitlab_email_enabled'] = true
gitlab_rails['gitlab_email_from'] = 'hitredrose@163.com'     # 发件箱地址
gitlab_rails['gitlab_email_display_name'] = 'gitlab.redrose2100.com'    # 显示名称
gitlab_rails['gitlab_email_reply_to'] = 'noreply@example.com'     # 提示不要回复
```

### （6） 重启docker
```bash
docker restart gitlab
```
### （7）进入docker容器里

```bash
docker exec -it gitlab bash
```

### （8）修改端口号

```bash
vi /opt/gitlab/embedded/service/gitlab-rails/config/gitlab.yml
```
如下，将端口修改为映射后的端口

### （9）重启gitlab
直接在docker中执行
```bash
gitlab-ctl restart
```
如：

```bash
root@cd6a79be7773:/etc/gitlab# gitlab-ctl restart
ok: run: alertmanager: (pid 4567) 1s
ok: run: gitaly: (pid 4582) 1s
ok: run: gitlab-exporter: (pid 4598) 1s
ok: run: gitlab-workhorse: (pid 4603) 1s
ok: run: grafana: (pid 4610) 1s
ok: run: logrotate: (pid 4619) 1s
ok: run: nginx: (pid 4631) 1s
ok: run: postgres-exporter: (pid 4636) 1s
ok: run: postgresql: (pid 4645) 1s
ok: run: prometheus: (pid 4653) 0s
ok: run: puma: (pid 4670) 1s
ok: run: redis: (pid 4679) 0s
ok: run: redis-exporter: (pid 4689) 1s
ok: run: sidekiq: (pid 4697) 1s
ok: run: sshd: (pid 4703) 1s
root@cd6a79be7773:/etc/gitlab
```
### （10）在浏览器打开 ip：端口号即可访问
这里需要注意，如果使用的是阿里云，需要配置安全组放开端口，如果使用二级域名，同样需要配置Nginx代理进行解析，

### （11）查看root默认密码

```bash
cat /docker/gitlab/etc/gitlab/initial_root_password
```
如：

### （12）使用root用户名以及上述查询到的密码登录
![](/static/upload/20220516_062242.png)

### （13）登录后依次点击【头像】-【Edit profile】-【password】，然后修改密码
![](/static/upload/20220516_062308.png)

### （14）至此，gitlab已经安装完成，并已修改密码
