1. Introduction of git

Git is a distributed version control, everyone has their own version library, and the version number of each submission is the world's only number generated by the sha-1 algorithm.

SVN is centralized version control, with only one version library. The version number is numbered sequentially from 1pm to 2pm.

Several concepts:

Index staging area-joined tracking but not submitted

Work area Workspace

Local repository local warehouse

Remote repository remote warehouse

A folder that, after executing git init, is initialized to a local repository. Generate a .git hidden folder

.git | Local warehouse

Abc.html | Workspace

De.html | Workspace

.git hides the inside of the folder:

Logs | folder

Objects | data submitted by the folder

Refs | folder

COMMIT_EDITMSG |

Config |

FETCH_HEAD |

HEAD |

Index | File staging area

ORIG_HEAD |

Sourcetreeconfig

Gitlab version control CE version

Download: https://about.gitlab.com/installation/#centos-7

Details: https://gitlab.com/gitlab-org/omnibus-gitlab/tree/master/doc/settings

Client uses: Git-2.10.2-64-bit.exe sourcetree

1. Download the gitlab installation package

The download speed of the official website is slow. It is recommended to download it first.

(1) https://about.gitlab.com/downloads/

(2)。 The latest version of https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/ubuntu/pool/trusty/main/g/gitlab-ce/ can be found in domestic sources.

(3) .yum source installs curl-sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash

two。 Installation dependency

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

Systemctl enable postfix

Systemctl start postfix

Firewall-cmd-permanent-add-service=http

Systemctl reload firewalld

3. Add yum source, install package

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

Sudo yum install gitlab-ce-y

Yum-- installroot specifies the installation path

Or

Curl-LJO https://packages.gitlab.com/gitlab/gitlab-ce/packages/el/7/gitlab-ce-XXX.rpm/download

Rpm-I gitlab-ce-XXX.rpm

4. Configure Startup GitLab

Gitlab-ctl reconfigure

Configuration file: / etc/gitlab/gitlab.rb

External_url 'http://tqsrv131-git' # #! This is the domain name or IP

5.EMail settings:

(1) / etc/gitlab/gitlab.rb

External_url 'http://60.205.222.133'

(2) enable postfix, (if not enabled in this example, use smtp)

Postfix profile:

Vi / etc/postfix/main.cf

Vi / var/log/mail.log

Gitlab_rails ['gitlab_email_enabled'] = true

Gitlab_rails ['gitlab_email_from'] =' huasaixiu@tianqiantek.cn'

Gitlab_rails ['gitlab_email_display_name'] =' GitLab'

Gitlab_rails ['gitlab_email_reply_to'] =' noreply@tianqiantek.cn'

(3) configure SMTP to send mail instead of SendMail/postfix

Gedit / etc/gitlab/gitlab.rb

External_url 'http://xx.xx.xx.xx'

# see https://gitlab.com/gitlab-org/omnibus-gitlab/tree/master/doc/settings

# Use smtp insttead of sendmail/postfix.

Gitlab_rails ['smtp_enable'] = true

Gitlab_rails ['smtp_address'] = "smtp.126.com"

Gitlab_rails ['smtp_port'] = 25

Gitlab_rails ['smtp_user_name'] = "system_mail_ul@126.com"

Gitlab_rails ['smtp_password'] = "xxxxx"

Gitlab_rails ['smtp_domain'] = "smtp.126.com"

Gitlab_rails ['smtp_authentication'] = "login"

Gitlab_rails ['smtp_enable_starttls_auto'] = true

Gitlab_rails ['smtp_tls'] = false

Gitlab_rails ['smtp_openssl_verify_mode'] =' peer'

Reconfigure

Gitlab-ctl reconfigure

test

Gitlab-rails console

Irb (main): 003Message Subject--test', 0 > Notify.test_email ('huasaixiu@tianqiantek.cn',' Message Subject--test', 'Message Body'). Deliver_now

Note: if it is an Ali CVM, you need to apply for port 25 unblocking, otherwise it will not work.

3) Web: visit

Http://xxx.xxx.xxx.xxx/

Log in to the default administrator password and user name for the first time according to the external_url access set above:

Username: root

Password: set the initial password based on the connection given by the email.

Gitlab closes open registration

Admin-- > settings-- > Sign-in Restrictions

Sign-upenbaled turns off the registration function

Sign-inenbaled turns off the registration login function

Set for internal use and do not disclose

4) use

First create a group, then use a group to create a project, and finally create a user and put it in the group

There are three permission levels for setting project, snippet and group:

Private is private and can only be accessed by yourself or members of the group

Internal all logged in users

Public is public and accessible to everyone.

Set up the project

5) the use of Git

Git Bash download address: https://git-scm.com/downloads

(1) add sshkey

Generate sshkey

Ssh-keygen-t rsa-C "$your_email"

Cat / .ssh/id_rsa.pub

Your_emai is your email address. Just enter all the time. This command generates a pair of public and private keys in C:\ Users\ .ssh directory and copies the contents of the public key (the file at the end of .pub).

(2)。 Save sshkey to gitlab

After logging in to your GitLab account, click "Profile Setting"-> "SSH Keys" in the upper right corner, enter the SSH Key title (customizable), and copy the copied id_rsa.pub content to Key, "Add Key".

(3)。 Start uploading code

Enter the project directory cd $project_root

Initialize the git warehouse git init

Add files to the warehouse git add.

Submit the code to the warehouse git commit-m 'init commit'

Link to git server

Git remote add origin git@example.com:namespace/projectname.git

Push code to server git push origin master

Some commonly used instructions in GitLab

Gitlab-ctl start/stop/restart/

The default log files for Gitlab are stored in the / var/log/gitlab directory

Gitlab-ctl tail

Gitlab-ctl tail nginx/gitlab_acces.log

Gitlab-ctl tail postgresql
