操作系统是centos7 64位 使用的是root用户
前提请先安装docker，系统内核必须3.10以上 内存最好4G以上 (这里是1G的)
执行uname -r 查看
[root@VM_104_126_centos ~]# uname -r 3.10.0-514.16.1.el7.x86_64
假设我公网ip是168.168.168.168
ps：如果你是内部使用，可以使用局域网ip假设你局域网ip是192.168.1.168 如果是局域网安装就用你局域网ip替换公网ip
先安装docker
[root@nanhaidetianzhi ~]# sudo tee /etc/yum.repos.d/docker.repo <<-’EOF’
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/7/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
EOF
[root@nanhaidetianzhi ~]# yum -y install docker-engine
[root@nanhaidetianzhi ~]# systemctl enable docker.service
[root@nanhaidetianzhi ~]# systemctl start docker
[root@nanhaidetianzhi ~]# systemctl status docker
这边的环境早就安装好Docker了。
运行systemctl status docker
[root@VM_104_126_centos ~]# systemctl status docker * docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled) Active: active (running) since Fri 2017-09-08 13:35:33 CST; 28min ago Docs: http://docs.docker.com Main PID: 30243 (dockerd-current) CGroup: /system.slice/docker.service |-30243 /usr/bin/dockerd-current --add-runtime docker-runc=/usr/libexec/docker/docker-runc-current --default-runtime=docker-runc --exec-opt native.cgroupdriver=systemd --userland-proxy-path=/usr/libexec/docker/docker-proxy-current --selinux-enabled --log-d... `-30247 /usr/bin/docker-containerd-current -l unix:///var/run/docker/libcontainerd/docker-containerd.sock --shim docker-containerd-shim --metrics-interval=0 --start-timeout 2m --state-dir /var/run/docker/libcontainerd/containerd --runtime docker-runc --run...

docker安装完成
ps:由于docker仓库在国外，国内长城防火墙的限制导致拉去很慢，可以去这个网站注册 进行加速下载
https://www.daocloud.io/mirror#accelerator-doc
直接选择对应操作系统，复制命令执行，这里是centos
[root@VM_104_126_centos ~]# curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://60037054.m.daocloud.io
docker version >= 1.12
{"registry-mirrors": ["http://60037054.m.daocloud.io"]}
Success.
You need to restart docker to take effect: sudo systemctl restart docker
好了。
然后重启docker服务（systemctl restart docker这个命令是重启）就可以加速了
如果你的电脑没有安装pwgen请先安装这个，（yum -y install pwgen）后面会用到

然后执行下面三条命令，从docker仓库拉去代码
docker pull sameersbn/gitlab docker pull sameersbn/redis docker pull sameersbn/postgresql
[root@VM_104_126_centos ~]# docker pull sameersbn/gitlab Using default tag: latest Trying to pull repository docker.io/sameersbn/gitlab ... latest: Pulling from docker.io/sameersbn/gitlab cb56c90f0b30: Pull complete 0acc551e5716: Pull complete 8956dcd35143: Pull complete 908242721214: Pull complete b44ff14dd3bb: Pull complete bfecf19f805b: Pull complete af5d9c80f987: Pull complete c62bc6caea23: Pull complete c2ede0fef898: Pull complete 8a2325c8c3e4: Pull complete 5b0c2d80b1a3: Pull complete bf00e79aff66: Pull complete Digest: sha256:2aac59cc3343d5ab6553349cba7f51ce34708be3a7c4b507b0d878e79d915aa1 [root@VM_104_126_centos ~]# docker pull sameersbn/redis Using default tag: latest Trying to pull repository docker.io/sameersbn/redis ... latest: Pulling from docker.io/sameersbn/redis 30d541b48fc0: Pull complete 8ecd7f80d390: Pull complete 46ec9927bb81: Pull complete 2e67a4d67b44: Pull complete 7d9dd9155488: Pull complete 14d49618a9fd: Pull complete aad64f368552: Pull complete e15b7db74be0: Pull complete Digest: sha256:b03bf1307ed31a9dff21e23d1ada62dc80e3f29fcc70582d51f4cf9895c9fecc [root@VM_104_126_centos ~]# docker pull sameersbn/postgresql Using default tag: latest Trying to pull repository docker.io/sameersbn/postgresql ... latest: Pulling from docker.io/sameersbn/postgresql c60055a51d74: Pull complete 755da0cdb7d2: Pull complete 969d017f67e6: Pull complete 37c9a9113595: Pull complete a3d9f8479786: Pull complete e43d9de53575: Pull complete a16c58ae6f28: Pull complete b55b7a197c94: Pull complete d330dd15576f: Pull complete a410f2b7d073: Pull complete Digest: sha256:68239871c61acc08bc52d703c02a7430ba63d2b02b1c5567ba59d9b1e5ffb10a
然后执行docker image就可以看见你拉去的镜像了。
[root@VM_104_126_centos ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/sameersbn/gitlab latest 06a14df77e35 45 hours ago 1.687 GB docker.io/redis latest d4f259423416 6 weeks ago 105.9 MB docker.io/sameersbn/redis latest d8f7b0e07097 6 weeks ago 203.4 MB docker.io/nginx latest 3448f27c273f 4 months ago 109.4 MB docker.io/sameersbn/postgresql latest 409a9e95e432 7 months ago 234 MB
然后按顺序执行下面语句，未完待续，尽请期待！
[root@VM_104_126_centos ~]#docker run --name gitlab-postgresql -d
--env ’DB_NAME=gitlabhq_production’
--env ’DB_USER=gitlab’ --env ’DB_PASS=password’
