1. 配置网卡及 Ubuntu 仓库源

1）配置网卡 eth0，本地内网网卡无需指定网关和域名服务器

network:
    version: 2
    renderer: networkd
    ethernets:
        eth0:
            dhcp4: no
            addresses: [192.168.1.30/24]

2）配置网卡 eth1，要保持以下两个字节的严格缩进，否则会导致网卡起不来

root@ubuntu1804:~# vim /etc/netplan/02-netcfg.yaml 
network:
         version: 2
         renderer: networkd
         ethernets:
                 eth1:
                        dhcp4: yes
                        addresses: [192.168.10.107/24]
                        gateway4: 192.168.10.1
                        nameservers:
                                 addresses: [223.6.6.6]

3）配置阿里云仓库源

root@ubuntu1804:~# vim /etc/apt/sources.list
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

4）更新仓库

root@ubuntu1804:~# apt update
root@ubuntu1804:~# apt update
Get:1 http://mirrors.aliyun.com/ubuntu bionic InRelease [242 kB]
Get:2 http://mirrors.aliyun.com/ubuntu bionic-security InRelease [88.7 kB]                                  
Get:3 http://mirrors.aliyun.com/ubuntu bionic-updates InRelease [88.7 kB]                                   
Get:4 http://mirrors.aliyun.com/ubuntu bionic-proposed InRelease [242 kB]

2. 安装 gitlab 包

1）下载 gitlab-ce 社区版包

root@ubuntu1804:~# ls /data/
gitlab-ce_11.11.5-ce.0_amd64.deb

2）安装 gitlab，要确定 gitlab 包适合此版本 ubuntu 系统

root@ubuntu1804:/data# dpkg -i gitlab-ce_11.11.5-ce.0_amd64.deb
root@ubuntu1804:/data# dpkg -i gitlab-ce_11.11.5-ce.0_amd64.deb 
Selecting previously unselected package gitlab-ce.
(Reading database ... 69294 files and directories currently installed.)
Preparing to unpack gitlab-ce_11.11.5-ce.0_amd64.deb ...
Unpacking gitlab-ce (11.11.5-ce.0) …   #等待安装完成 

3）此时无法识别主机，需修改 git 配置文件，指定主机

root@ubuntu1804:/data# vim /etc/gitlab/gitlab.rb 
    external_url 'http://192.168.1.30'  #修改指定的 ip 主机 

4）配置完进行 gitlab 初始化

root@ubuntu1804:/data# gitlab-ctl reconfigure

3. 命令操作

1）进入数据库命令行

root@ubuntu1804:~# gitlab-psql
gitlabhq_production-# \db
                 List of tablespaces
        Name    |    Owner    | Location 
------------+-------------+----------
 pg_default | gitlab-psql | 
 pg_global  | gitlab-psql | 
(2 rows)

2）查看 gitlab 的运行状态

root@ubuntu1804:~# gitlab-ctl status
run: alertmanager: (pid 4704) 1841s; run: log: (pid 4373) 1867s
run: gitaly: (pid 4475) 1844s; run: log: (pid 3483) 2026s

run: redis: (pid 3417) 2034s; run: log: (pid 3442) 2031s
run: redis-exporter: (pid 4561) 1842s; run: log: (pid 4202) 1881s
run: sidekiq: (pid 3967) 1920s; run: log: (pid 3983) 1916s
run: unicorn: (pid 3908) 1926s; run: log: (pid 3957) 1923s

3）gitlab 服务命令行的启动、停止、重启

gitlab-ctl start/stop/restart gitlab

4) 查看 gitlab 的 nginx 服务组件的日志

root@ubuntu1804:~# gitlab-ctl tail nginx
==> /var/log/gitlab/nginx/current <==

==> /var/log/gitlab/nginx/access.log <==

==> /var/log/gitlab/nginx/error.log <==

==> /var/log/gitlab/nginx/gitlab_error.log <==

==> /var/log/gitlab/nginx/gitlab_access.log <==
192.168.1.1 - - [21/Jul/2019:10:36:00 +0800] "GET / HTTP/1.1" 302 99 """Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3724.8 Safari/537.36"
……

4. 浏览器访问 gitlab

1）设置新的密码，默认登录的用户为 root

2）登录后默认的界面

3）点击 setting，在点击 sign-up 可以设置是否允许创建新用户

4）去掉对勾，禁止创建新账户

5）再点击保存修改生效

6）此时登出账号时，就没有注册用户的选项，只能用已有的账户登录

7）创建一个新用户时会受到邮件通知

8）创建不同的项目、组、账户，将特定用户放到特定的组，实现特定用户对某些项目有查看权限

9）返回到项目列表，并进入一个项目

10）点击 New file

11）输入一个索引测试页面，再点击提交

12）查看项目的 clone 地址

13）客户端 clone

root@ubuntu1804:/data/src# git clone http://192.168.1.30/root/web-page.git
Cloning into 'web-page'...
remote: Enumerating objects: 3, done.
remote: Counting objects: 100% (3/3), done.
remote: Total 3 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.

14）项目代码克隆成功

root@ubuntu1804:/data/src# ls
web-page
root@ubuntu1804:/data/src# cat web-page/index.html 
<h>hello jie!</h1>

15）在客户端修改 index.html

root@ubuntu1804:/data/src/web-page# cat index.html 
<h>hello jie!</h1>
<h>hello kobe!</h1>
<h>hello curry!</h1>
<h>hello rose!</h1>

16）先添加到本地暂存区（提交代码到 gitlab 服务器时，命令都必须在克隆下来的文件夹环境中执行）

root@ubuntu1804:/data/src/web-page# git add index.html

17）在提到工作区

root@ubuntu1804:/data/src/web-page# git commit -m 'v6'
[master 1202723] v6
 1 file changed, 4 insertions(+), 1 deletion(-)

18）然后在直接提交到 gitlab 仓库 web 端

root@ubuntu1804:/data/src/web-page# git push     #其中 git pull 为获取代码到本地
Username for 'http://192.168.1.30': root     #要求输入登录 gitlab 的 web 端的用户名                             
Password for 'http://root@192.168.1.30':    #再输入登录 gitlab 的 web 端的用户密码  
Counting objects: 3, done.

Compressing objects: 100% (2/2), done.
Writing objects: 100% (3/3), 268 bytes | 268.00 KiB/s, done.
Total 3 (delta 0), reused 0 (delta 0)
To http://192.168.1.30/root/web-page.git
     ecc001d..1202723  master -> master     #提交完成 

19）在 web 端 gitlab 仓库查看，项目 index.html 内容被更改，说明成功提交

20）再次修改 index.html 文件，然后在上传 v7 版本的 index.html 到 gitlab 的服务端

5.gitlab 的一些基本命令操作（以下命令操作命令都必须在克隆下来的文件夹环境中执行，否则无法执行令）

1）客户端查看当前版本号为 v7

root@ubuntu1804:/data/src/web-page# git reset --hard HEAD
HEAD is now at 952e66b v7

2）查看 v7 版索引

root@ubuntu1804:/data/src/web-page# cat index.html 
<h>hello jie!</h1>
<h>hello kobe!</h1>
<h>hello curry!</h1>
<h>hello rose!</h1>
<h>hello jordan!</h1>
<h>hello jordan!</h1>
<h>hello howard!</h1>

3）若想回滚到 v6 版本，则操作如下命令进行回滚

root@ubuntu1804:/data/src/web-page# git reset --hard HEAD^
HEAD is now at 9cb6bf6 v6

4）再查看 v6 版本索引文件

root@ubuntu1804:/data/src/web-page# cat index.html 
<h>hello jie!</h1>
<h>hello kobe!</h1>
<h>hello curry!</h1>
<h>hello rose!</h1>
<h>hello jordan!</h1>
<h>hello jordan!</h1>

5）查看每次提交的目标代码 id 号，

root@ubuntu1804:/data/src/web-page# git reflog
9cb6bf6 (HEAD -> master) HEAD@{0}: reset: moving to HEAD^
952e66b (origin/master, origin/HEAD) HEAD@{1}: reset: moving to HEAD
952e66b (origin/master, origin/HEAD) HEAD@{2}: commit: v7
9cb6bf6 (HEAD -> master) HEAD@{3}: commit: v6
03e27be (tag: v1.4) HEAD@{4}: commit: v7
1202723 HEAD@{5}: commit: v6
ecc001d HEAD@{6}: clone: from http://192.168.1.30/root/web-page.git

6）也可指定目标代码 id 号，实现回滚

root@ubuntu1804:/data/src/web-page# git reset --hard 9cb6bf6

7) 查看当前所属的分支，默认为 master 主分支

root@ubuntu1804:/data/src/web-page# git branch
* master

8）创建并切换到新分支

root@ubuntu1804:/data/src/web-page# git checkout -b operations
Switched to a new branch 'operations'

9）再次列出所有分支分支

root@ubuntu1804:/data/src/web-page# git branch
    master
* operations

10）切换回到主分支

root@ubuntu1804:/data/src/web-page# git checkout master
Switched to branch 'master'
Your branch is behind 'origin/master' by 1 commit, and can be fast-forwarded.
    (use "git pull" to update your local branch)
root@ubuntu1804:/data/src/web-page# git branch
* master
    operations

6. 数据备份

1）备份前先要暂停 gitlab 的两个数据服务，避免在备份时开发人员继续提交代码至 gitlab 中，导致数据不完整

root@ubuntu1804:~# gitlab-ctl stop sidekiq
ok: down: sidekiq: 0s, normally up
root@ubuntu1804:~# gitlab-ctl stop nunicorn

2）手动创建备份

root@ubuntu1804:~# gitlab-rake gitlab:backup:create

3）gitlab 默认备份数据名称及路径，为压缩文件

root@ubuntu1804:~# ll /var/opt/gitlab/backups/1563709800_2019_07_21_11.11.5_gitlab_backup.tar 
-rw------- 1 git git 92160 Jul 21 19:50 /var/opt/gitlab/backups/1563709800_2019_07_21_11.11.5_gitlab_backup.tar

4）在 gitlab 的 web 端目前存在的项目、用户和组

5）先删除掉几个项目、用户或组

7. 客户端数据恢复

1）在恢复数据之前也要先关闭 gitlab 的两个数据服务

root@ubuntu1804:~# gitlab-ctl stop sidekiq
ok: down: sidekiq: 0s, normally up
root@ubuntu1804:~# gitlab-ctl stop unicorn
ok: down: unicorn: 0s, normally up

2）执行恢复备份数据命令

root@ubuntu1804:~# gitlab-rake gitlab:backup:restore /var/opt/gitlab/backups/1563709800_2019_07_21_11.11.5_gitlab_backup.tar

3）在开启 gitlab 的两个数据服务

oot@ubuntu1804:~# gitlab-ctl start sidekiq
ok: run: sidekiq: (pid 80094) 1s
root@ubuntu1804:~# gitlab-ctl start  unicorn
ok: run: unicorn: (pid 80191) 0s

4）gitlab 的 web 端访问测试，可以看到删除的项目、用户、组全部恢复
