Git remote version Library

1. Distributed version control system

★ is based on network protocols.

Http,https,ssh,git

two。 Clone operation

★ git clone

★ original version inventory is stored in refs/heads/

3.git server

★ protocol

Local Protocol (local), HTTP/HTTPS Protocol, SSH Protocol, Git Protocol

☉ local protocol

URL:

/ path/to/repo.git

File:///path/to/repo.git

☉ Git protocol: provided by git-daemon program, listening on port 9418 of tcp; only "read" operation is supported, without any authentication function (open source projects are supported)

URL:

Git://host/path/to/repo.git

Git://host/~user/path/to/repo.git

☉ SSH protocol

URL:

Ssh:// [USER@] host [: port] / path/to/repo.git

Ssh:// [USER@] host [: port] / ~ USERNAME/path/to/repo.git

URL2:

[USER@] hostpath/torepo.git

☉ HTTP/HTTPS protocol

1.6.5 Murray: dumb http protocol

1.6.6protocols: intelligent http protocol (read / write / authentication)

URL:

Http://host/path/to/repo.git

1. Distributed version control system

★ remote version Library

An entity defined in the configuration file

[remote "NAME"]

☉ consists of two parts:

Part one: URL

The second part: refspec, which defines the mapping relationship between the namespaces of one version library and other version libraries.

☉ syntax format:

+ source:destination (local branch and target branch of the map)

Refs/heads/NAME: local branch

Refs/remotes/NAME: remote tracking branch

Eg:

[remote "publish"]

Url= http://HOST/pub/repo_name.git

Push= + refs/heads/*:refs/remotes/origin/*

What it looks like:

Remote.publish.url

Remote.publish.push

The ★ git remote command manages the remote warehouse

Git protocol demo:

Install the git server on the node2 server and start the service

[root@node2~] # yum install git-daemon [root@node1 huihui] # rpm-ql git-daemon/usr/lib/systemd/system/git.socket # is an instantaneous daemon You can start / usr/lib/systemd/system/git@.service/usr/libexec/git-core/git-daemon/usr/share/doc/git-daemon-1.8.3.1/usr/share/doc/git-daemon-1.8.3.1/git-credential-cache--daemon.html/usr/share/doc/git-daemon-1.8.3.1/git-credential-cache--daemon.txt/usr/share/doc/git-daemon-1 directly. Storage location of 8.3.1/git-daemon.html/usr/share/doc/git-daemon-1.8.3.1/git-daemon.txt/usr/share/man/man1/git-credential-cache--daemon.1.gz/usr/share/man/man1/git-daemon.1.gz/var/lib/git # git warehouse Equivalent to the root directory [root@node2 ~] # cat / usr/lib/systemd/system/git@. Service [Unit] Description=Git Repositories Server DaemonDocumentation=man:git-daemon (1) [Service] User=nobody # modified-- the path after base-path can change the root directory of the git repository ExecStart=-/usr/libexec/git-core/git-daemon-- base-path=/var/lib/git-- export-all-- user- Path=public_git-- syslog-- inetd-- verboseStandardInput=socket# startup service And check port 9418 [root@node2 ~] # systemctl start git.socket [root@node2 ~] # ss-tnl of tcp | grep 9418LISTEN 0128:: 9418:: *

two。 Create a naked warehouse under the git root on the nod2 remote server without the need for a working directory

[root@node2 ~] # cd / var/lib/git/ [root@node2 git] # git init-- bare myproject.git initializes the empty Git version library at / var/lib/git/myproject.git/ [root@node2 git] # ls myproject.git/branches config description HEAD hooks info objects refs

3. Clone the remote repository of the node2 node in the node1 node

[root@node1] # git clone git://192.168.0.102/myproject.gitCloning into 'myproject'...warning: You appear to have cloned an empty repository. [root@node1 myproject] # ls-a. .. .git [root@node1 myproject] # git config-luser.name=wataouser.email=wangzhangtao@pachiratech.comcore.repositoryformatversion=0core.filemode=truecore.bare=falsecore.logallrefupdates=trueremote.origin.url=git://192.168.0.108/myproject.gitremote.origin.fetch=+refs/heads/*:refs/remotes/origin/*branch.master.remote=originbranch.master.merge=refs/heads/master

Http protocol demo:

1. Install httpd and make sure there are alias,env and cgi modules

[root@node2~] # yum install httpd# ensures that there are three modules [root@node2~] # httpd-M | grep-Ei "\
