一、安装Docker

1.安装docker依赖包

[root@gitlab ~]# yum -y install yum-utils device-mapper-persistent-data lvm2

2.添加Docker-ce镜像源并安装

1.1）国外源（适合在国外工作的朋友）

[root@gitlab ~]# yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo

1.2）国内阿里云源（适合在国内工作的朋友）

[root@gitlab ~]# yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

2）服务器的包信息下载到本地电脑缓存起来

[root@gitlab ~]# yum makecache fast

3）安装docker CE

[root@gitlab ~]# yum -y install docker-ce

4)配置下载docker镜像加速器

国外加速器：

[root@gitlab ~]# curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://bc437cce.m.daocloud.io

国内阿里云加速器：

vim /etc/docker/daemon.json

#输入下面内容并保存：

{
"registry-mirrors": [https://9w1hl6qt.mirror.aliyuncs.com]
}

5)重载systemctl并自动和开启自启动docker

[root@gitlab ~]# systemctl daemon-reload
[root@gitlab ~]# systemctl start docker
[root@gitlab ~]# systemctl enable docker
[root@gitlab ~]# docker --version 
Docker version 18.09.0, build 4d60db4

二、安装Docker-compose

下载Docker-compose二进制文件并添加执行权限

[root@gitlab ~]# curl -L https://github.com/docker/compose/releases/download/1.23.2/docker-compose-`uname -s-uname -m` -o /usr/local/bin/docker-compose
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 617 0 617 0 0 590 0 --:--:-- 0:00:01 --:--:-- 590
100 11.2M 100 11.2M 0 0 498k 0 0:00:23 0:00:23 --:--:-- 737k
[root@gitlab ~]# chmod +x /usr/local/bin/docker-compose
[root@gitlab ~]# docker-compose --version
docker-compose version 1.23.2, build 1110ad01

三、安装Gitlab

1）编辑docker-compose的yml文件

[root@gitlab ~]# mkdir gitlab
[root@gitlab ~]# cd gitlab
[root@gitlab gitlab]# vim docker-compose.yml
version: '2'
services:
  gitlab:
   image: 'twang2218/gitlab-ce-zh:latest'
   container_name: "gitlab"
   restart: unless-stopped
   privileged: true
   hostname: 'gitlab'
   environment:TZ: 'Asia/Shanghai'GITLAB_OMNIBUS_CONFIG: |
    external_url 'http://ip或者用nginx做反代的域名'
    gitlab_rails['time_zone'] = 'Asia/Shanghai'
    gitlab_rails['smtp_enable'] = true
    gitlab_rails['smtp_address'] = "smtp.163.com"
    gitlab_rails['smtp_port'] = 465
    gitlab_rails['smtp_user_name'] = "xxxxxx@163.com"
    gitlab_rails['smtp_password'] = "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_from'] = 'xxxxxx@163.com'
    gitlab_rails['gitlab_shell_ssh_port'] = 22
   ports:- '8181:80'- '8443:443'- '22:22'
   volumes:- /opt/gitlab/config:/etc/gitlab
    - /opt/gitlab/data:/var/opt/gitlab
    - /opt/gitlab/logs:/var/log/gitlab

端口映射说明以及注意事项：

gitlab镜像官方推荐容器80端口映射宿主机8181端口

gitlab镜像官方推荐容器443端口映射宿主机8443端口

gitlab镜像官方推荐容器22端口映射宿主机22端口

⭐️头两行不能顶头写，要分别都空一行，可以去yml文件检测网站进行检测：

www.bejson.com/validators/yaml_edi...

2)创建相关目录

[root@gitlab gitlab]# mkdir -p /opt/gitlab/{config,data,logs}
[root@gitlab gitlab]# ls -l /opt/gitlab/
total 0
drwxr-xr-x 2 root root 6 Dec 22 12:03 config
drwxr-xr-x 2 root root 6 Dec 22 12:03 data
drwxr-xr-x 2 root root 6 Dec 22 12:03 logs

目录说明如下：

config 存储 GitLab 配置信息

data 存储数据库

logs 存储日志

3)拉取gitlab中文版镜像

[root@gitlab gitlab]# docker pull twang2218/gitlab-ce-zh:latest

Status: Downloaded newer image for twang2218/gitlab-ce-zh:latest

[root@gitlab gitlab]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
twang2218/gitlab-ce-zh latest 18da462b5ff5 4 months ago 1.61GB

4)启动gitlab的容器

在启动前，先要修改宿主机的22端口，因为宿主机占用了22端口，所以启动容器会失败，因为映射不过来，修改如下：

vim /etc/ssh/sshd_config

默认在第17行修改：Port 2222

修改后，重启sshd：systemctl restart sshd

[root@gitlab gitlab]# netstat -tulnp | grep 22
tcp 0 0 0.0.0.0:2222 0.0.0.0: LISTEN 31889/sshd
tcp6 0 0 :::2222 ::: LISTEN 31889/sshd

正式启动：

[root@gitlab gitlab]# docker-compose up -d
Creating network "gitlab_default" with the default driver
Creating gitlab ... done

[root@gitlab gitlab]# docker-compose ps
Name Command State Ports
gitlab /assets/wrapper Up (healthy) 0.0.0.0:22->22/tcp, 0.0.0.0:8443->443/tcp, 0.0.0.0:8181->80/tcp

[root@gitlab gitlab]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
814e559dc728 twang2218/gitlab-ce-zh:latest "/assets/wrapper" 5 minutes ago Up 5 minutes (healthy) 0.0.0.0:22->22/tcp, 0.0.0.0:8181->80/tcp, 0.0.0.0:8443->443/tcp gitlab

5)gitlab设置开机启动

[root@gitlab gitlab]# chmod +x /etc/rc.local
[root@gitlab gitlab]# ls -l /etc/rc.local
lrwxrwxrwx 1 root root 13 Dec 3 14:31 /etc/rc.local -> rc.d/rc.local
[root@gitlab gitlab]# echo "cd /root/gitlab && docker-compose up -d" >> /etc/rc.local
[root@gitlab gitlab]# tail -1 /etc/rc.local
cd /root/gitlab && docker-compose up -d

6)gitlab管理界面

转载www.jb51.net/article/153399.htm

地址：在浏览器输入yml文件的第12行ip或者域名

用户：root

密码：首次登陆需要手动设置密码

如下图所示：
