centos7.4+GitLab部署
GitLab 是一个用于仓库管理系统的开源项目，使用Git作为代码管理工具，并在此基础上搭建起来的web服务。系统环境准备
建议：内存4G以上不然带不动

通常我们在部署的时候会发现80和8080端口均被占用，那么我们就需要修改gitlab的默认端口。
#gitlab配置文件路径，用于gitlab如何调用80和8080的服务等。
/etc/gitlab/gitlab.rb
编辑配置文件并找到 unicorn 配置，将端口修改成想要的端口
修改/etc/gitlab/gitlab.rb
vim /etc/gitlab/gitlab.rb
#unicorn['port'] = 8080 修改 8070默认是注释的去掉前面的#
unicorn['port'] = 8070
#nginx['listen_port'] = nil 修改 8090默认是注释的去掉前面的#
nginx['listen_port'] = 8090
修改/var/opt/gitlab/gitlab-rails/etc/unicorn.rb
vim /var/opt/gitlab/gitlab-rails/etc/unicorn.rb
#listen "127.0.0.1:8080", :tcp_nopush => true
listen "127.0.0.1:8070", :tcp_nopush => true
修改默认的gitlab nginx的web服务80端 /var/opt/gitlab/nginx/conf/gitlab-http.conf
vim /var/opt/gitlab/nginx/conf/gitlab-http.conf
#listen *:80;
listen *:8090;
#加载配置文件并启动，时间稍长
# gitlab-ctl reconfigure
#gitlab-ctl其他命令
启动：gitlib-ctl start
关闭：gitlab-ctl stop
重启：gitlab-ctl restart
重载配置：gitlab-ctl reconfigure
查看状态：gitlab-ctl status
#查看端口保证80端口不被占用
# lsof -i:80
COMMAND PID USER FD TYPE DEVICE>
nginx 700 root 7uIPv416903 0t0TCP *:http (LISTEN)
nginx 804 gitlab-www 7uIPv416903 0t0TCP *:http (LISTEN)
浏览器登录gitlab，输入http://服务器ip:配置的nginx端口，进入下图：
设置一个密码后，使用 root 用户进行登录。
新建一个项目
那么我们怎样为 GitLab 的账号添加 SSH keys 呢
1).首先打开 linux 服务器，输入命令：ls -al ~/.ssh，检查是否显示有> 2).在 bash 中输入 ssh-keygen -t rsa -C ”yourEmail@example.com” ,注意这个地方的邮箱地址地址替换成你自己的邮箱地址即可，在显示如下的输出后一直按回车即可：
# useradd web-gitlab
# su !$
su web-gitlab
$
$
$ ssh-keygen -t rsa -C ”yourEmail@example.com”
Generating public/private rsa key pair.
Enter file in which to save the key (/home/web-gitlab/.ssh/id_rsa):
Created directory '/home/web-gitlab/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your>
Your public key has been saved in /home/web-gitlab/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:hwumGaUbZy7pD/R1LmaRC4NV42NToJZIuqsv1CMyhuo ”yourEmail@example.com”
The key's randomart image is:
+-------+
| . +.. |
| o . = o |
|. . * = |
| . * . = |
|. o * B S o |
|++ = & = B |
|=.o O o * . |
|o. . o o . |
|oE. ... |

$
在这里可以看到>
$ cd /home/web-gitlab/

$
$ ll

$
$ ll .ssh/
total 8
-rw------- 1 web-gitlab web-gitlab 1679 Apr 28 10:42>
-rw-r--r-- 1 web-gitlab web-gitlab402 Apr 28 10:42>
3).打开>
$ cat .ssh/id_rsa.pub
4).打开 GitLab 账户，添加 SSH Keys:
这样就添加了一个SSH key。
5).完成上面的步骤之后就可以使用ssh来连接GitLab，并进行相应的操作了。
我们可以通过 ssh 来 clone 项目
# su web-gitlab
$
$ cd /home/web-gitlab/
$ git clone git@服务器IP:root/test-demo.git
Cloning into 'test-demo'...
The authenticity of host '服务器IP (服务器IP)' can't be established.
ECDSA key fingerprint is SHA256:+CWe+3ROJVtuClFaH425BsTSYf+c9vTuhHF/6jTr4TI.
ECDSA key fingerprint is MD5:63:c6:8a:1a:59:fa:b8:ec:22:cb:29:dd:68:57:d4:3d.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '服务器IP' (ECDSA) to the list of known hosts.
warning: You appear to have cloned an empty repository.

$ ll

drwxrwxr-x 3 web-gitlab web-gitlab 4096 Apr 28 11:03 test-demo
这就是我们通过 ssh 克隆下来的项目。
