Gitlab的概念

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。安装方法是参考GitLab在GitHub上的Wiki页面。Gitlab是目前被广泛使用的基于git的开源代码管理平台, 基于Ruby on Rails构建, 主要针对软件开发过程中产生的代码和文档进行管理, Gitlab主要针对group和project两个维度进行代码和文档管理, 其中group是群组, project是工程项目, 一个group可以管理多个project, 可以理解为一个群组中有多项软件开发任务, 而一个project中可能包含多个branch, 意为每个项目中有多个分支, 分支间相互独立, 不同分支可以进行归并。

定义

GitLab是由GitLabInc.开发，使用MIT许可证的基于网络的Git仓库管理工具，且具有wiki和issue跟踪功能。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。

用到的git指令

git init ：初始化.git文件夹
git add 文件名：从本地工作区添加文件入暂存区
git add -A：从本地工作区添加全部文件入暂存区
git commit -m “添加的备注” 文件名：暂存区给文件备注确认，记录为一个版本
git commit -m “添加的备注” 文件名：暂存区全部文件备注确认，记录为一个版本
git log：查看历史版本记录
git status：查看文档修改记录，红色为未add内容，绿色为可以commit内容
git push 地址名本地分支:远程库分支：将暂存区代码推入远程库
git remove add 地址名地址url：远程库操作
git branch -M 分支名：创建分支

gitlab的安装与配置

gitlab-ce.repo源包

vim /etc/yum.repos.d/gitlab-ce.repo
[gitlab-ce]
name=Gitlab CE Repository
baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever/
gpgcheck=0
enabled=1


#yum makecache

或者这样装wget安装

wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-15.2.2-ce.0.el7.x86_64.rpm

改主机域名

[root@localhost ~]# hostnamectl set-hostname gitlab.example.com
[root@localhost ~]# bash
[root@gitlab ~]#

配置 hosts

[root@gitlab ~]# cat /etc/hosts
192.168.100.17   gitlab.example.com

安装gitlab依赖软件及获取 GPG 密钥

yum install -y curl policycoreutils openssh-server openssh-clients postfix

rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

安装 postfix 并启动

yum install postfix
systemctl start postfix
systemctl enable  postfix

安装gitlab-ce

curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
yum -y install gitlab-ce

手动配置ssl证书

1.创建私有密钥

[root@gitlab ~]# mkdir -p /etc/gitlab/ssl
[root@gitlab ~]# openssl genrsa -out "/etc/gitlab/ssl/gitlab.example.com.key" 2048
Generating RSA private key, 2048 bit long modulus
...+++
........................................+++
e is 65537 (0x10001)

2.创建私有证书

[root@gitlab ~]# cd /etc/gitlab/ssl
[root@gitlab ssl]# ls
gitlab.example.com.key
[root@gitlab ssl]# openssl req -new -key "/etc/gitlab/ssl/gitlab.example.com.key" -out "/etc/gitlab/ssl/gitlab.example.com.csr"
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN          CN  ##国家
State or Province Name (full name) []:SX      SX   ##省份
Locality Name (eg, city) [Default City]:XA    XA   ##城市  
Organization Name (eg, company) [Default Company Ltd]:    ##空格
Organizational Unit Name (eg, section) []:                ##空格
Common Name (eg, your name or your server's hostname) []:gitlab.example.com    
Email Address []:123456@qq.com                 ##邮箱地址

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:123456                ## 密码
An optional company name []:                  ##空格
[root@gitlab ssl]# ls
gitlab.example.com.csr  gitlab.example.com.key

3.创建CRT签署证书

安装完成，创建好了ssl密钥和证书
在ssl目录下ll
可以看到ssl密钥和证书
利用ssl密钥和证书创建签署证书

[root@gitlab ssl]# openssl x509 -req -days 365 -in "/etc/gitlab/ssl/gitlab.example.com.csr" -signkey "/etc/gitlab/ssl/gitlab.example.com.key" -out "/etc/gitlab/ssl/gitlab.example.com.crt"
Signature ok
subject=/C=CN/ST=SX/L=XA/O=Default Company Ltd/CN=gitlab.example.com/emailAddress=123456@qq.com
Getting Private key
[root@gitlab ssl]# ll /etc/gitlab/ssl/
总用量 12
-rw------- 1 root root 1273 8月   8 15:52 gitlab.example.com.crt
-rw------- 1 root root 1070 8月   8 15:52 gitlab.example.com.csr
-rw------- 1 root root 1679 8月   8 15:50 gitlab.example.com.key

4.利用openssl签署pem 证书

root@gitlab ssl]# openssl x509 -req -days 365 -in "/etc/gitlab/ssl/gitlab.example.com.csr" -signkey "/etc/gitlab/ssl/gitlab.example.com.key" -out "/etc/gitlab/ssl/gitlab.example.com.crt"
Signature ok
subject=/C=CN/ST=SX/L=XA/O=Default Company Ltd/CN=gitlab.example.com/emailAddress=123456@qq.com
Getting Private key
[root@gitlab ssl]# 
[root@gitlab ssl]# openssl dhparam -out /etc/gitlab/ssl/dhparams.pem  2048
Generating DH parameters, 2048 bit long safe prime, generator 2
This is going to take a long time
..............................+..............................................................................................................................................................................................................................+.+..........................................................+...........................................................................................................................................+...........................................................................................................................................................................................................................................................+.....................................................................................+.........................................

5.更改ssl下的所有证书权限

[root@gitlab ssl]# chmod 600 *
[root@gitlab ssl]# ll
总用量 16
-rw------- 1 root root  424 8月   8 15:53 dhparams.pem
-rw------- 1 root root 1273 8月   8 15:52 gitlab.example.com.crt
-rw------- 1 root root 1070 8月   8 15:52 gitlab.example.com.csr
-rw------- 1 root root 1679 8月   8 15:50 gitlab.example.com.key

6.配置证书到gitlab配置文件中

[root@gitlab ssl]# vim /etc/gitlab/gitlab.rb 
external_url 'https://gitlab.example.com'      ###改为https开头
nginx['redirect_http_to_https'] = true           ###取消#号更改注释并为true  1397行
# nginx['ssl_certificate'] = "/etc/gitlab/ssl/gitlab.example.com.crt"     ###更改路径
# nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/gitlab.example.com.key"     ###更改路径
# nginx['ssl_dhparam'] = "/etc/gitlab/ssl/dhparams.pem"   ##更改路径###   # Path to dhparams.pem, eg.  /etc/gitlab/ssl/dhparams.pem

7.更改完之后初始化命令执行

[root@gitlab ssl]# gitlab-ctl reconfigure  
....
....
....
Running handlers:
[2022-08-09T15:04:10+08:00] INFO: Running report handlers
Running handlers complete
[2022-08-09T15:04:10+08:00] INFO: Report handlers complete
Infra Phase complete, 3/818 resources updated in 13 seconds
gitlab Reconfigured!      
# 出现这个表示配置没有问题！

[root@gitlab ssl]# gitlab-ctl status
[root@gitlab ssl]#gitlab-ctl restart

[root@gitlab conf]# 
[root@gitlab conf]#  gitlab-ctl restart sidekiq 
ok: run: sidekiq: (pid 17327) 0s

8.对nginx配置

[root@gitlab ssl]#cd /var/opt/gitlab/nginx/conf
[root@gitlab conf]# ls
gitlab-health.conf  gitlab-http.conf  nginx.conf  nginx-status.conf
[root@gitlab conf]# vim gitlab-http.conf  
server_name gitlab.example.com;
rewrite ^(.*)$ https://$host$1 permanent;      ####需要添加的配置 注：（配置在80端口）

9.重启gitlab

[root@gitlab ssl]#  gitlab-ctl restart 
ok: run: alertmanager: (pid 15710) 0s
ok: run: gitaly: (pid 15723) 1s
ok: run: gitlab-exporter: (pid 15736) 0s
ok: run: gitlab-kas: (pid 15738) 0s
ok: run: gitlab-workhorse: (pid 15747) 1s
ok: run: grafana: (pid 15755) 0s
ok: run: logrotate: (pid 15765) 1s
ok: run: nginx: (pid 15775) 0s
