centos7+docker快速搭建gitlab服务流程步骤
最近我打算整个docker swarm集群架构玩玩，安装好docker后第一步就是先整个gitlab
先天条件：
1.准备centos7系统, 配置好网络ip、修改主机名
[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=eth0
UUID=9a65b9e5-7f65-46d8-bbb3-112eee88a0e1
DEVICE=eth0
ONBOOT=yes
IPADDR=172.18.1.150
NETMASK=255.255.255.0
GATEWAY=172.18.1.1
DNS1=114.114.114.114
IPV6_PRIVACY=no
[[email protected] ~]# cat /etc/hostname
master //然后重启
[[email protected] ~]# reboot 2.修改ssh端口 (这里特别注意，配置好了之后在注销22端口)
[[email protected] ~]# vi /etc/ssh/sshd_conf
//修改如下
#Port 22
Port 22250
//重启ssh
[[email protected] ~]# systemctl restart sshd.service3.关闭防火墙及SELinux，或添加ssh新端口
[[email protected] ~]# semanage port -a -t ssh_port_t -p tcp 22250
[[email protected] ~]# semanage port -l | grep ssh
ssh_port_t tcp 22250, 22
[[email protected] ~]# systemctl stop iptables.service
[[email protected] ~]# systemctl stop firewalld.service4.centos7中docker已经安装好
[[email protected] ~]# docker version

[[email protected] ~]# cat /etc/docker/daemon.json
{"registry-mirrors": ["https://ft5scn3r.mirror.aliyuncs.com"]}废话不多说直接上代码：
//Docker启动一个Gitlab服务
[[email protected] ~]# sudo docker run -d --hostname master \
> --publish 443:443 --publish 80:80 --publish 22:22 \
> --name gitlab --restart always --volume /srv/gitlab/config:/etc/gitlab \
> --volume /srv/gitlab/logs:/var/log/gitlab \
> --volume /srv/gitlab/data:/var/opt/gitlab \
> gitlab/gitlab-ce:latest

如果遇到下面错误
docker: Error response from daemon: driver failed programming external connectivity on endpoint gitlab (bb7b5466741624d55cc821de02e80d5f5e6a5b2d943efccd04e16d59a698f748): (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 443 -j DNAT --to-destination 172.17.0.2:443 ! -i docker0: iptables: No chain/target/match by that name.
(exit status 1)).解决方式：(docker服务启动时定义的自定义链被清掉了,需重启docker)
[[email protected] ~]# systemctl restart docker//看看镜像跟容器
[[email protected] ~]# docker ps -a

到这你以为OK了吗?
并没有，首次登录Gitlab需要重置密码，默认用户名为root
重置gitlab用户root的密码步骤：
[[email protected] ~]# docker exec -it f4e24320bcde /bin/sh
# ls
RELEASE bin dev home lib32 libx32 media opt root sbin sysusr
assets boot etc lib lib64 linuxrc mnt proc run srv tmpvar

注意那个错误是什么引起的
好了，到这就算是重置root密码为htz123456
web登录一下看看：
退出容器进入宿主机中操作 : (题外话)
按住Ctrl后先按p，在按q
