服务器评测
一、Git简介
- Git是一个开源的分布式版本控制系统，用于敏捷高效地处理任何或小或大的项目。
- Git 是 Linus Torvalds 为了帮助管理 Linux 内核开发而开发的一个开放源码的版本控制软件。
- Git 与常用的版本控制工具 CVS, Subversion 等不同，它采用了分布式版本库的方式，不必服务器端软件支持。
二、Git安装
1.CentOS7安装Git
[root@server-1 ~]# yum install -y git
2.查看安装的Git版本
[root@server-1 ~]# git –version
git version 1.8.3.1
3.创建git安装目录并初始化
[root@server-1 ~]# mkdir /data/git/
[root@server-1 ~]# cd /data/git/
[root@server-1 git]# git init
Initialized empty Git repository in /data/git/.git/
初始化后在该目录下会生成.git隐藏目录
[root@server-1 git]# ls -la
total 0
drwxr-xr-x. 3 root root 18 Apr 8 09:07 .
drwxr-xr-x. 5 root root 45 Apr 8 09:05 ..
drwxr-xr-x. 7 root root 119 Apr 8 09:07 .git
[root@server-1 git]# ls .git/
branches config description HEAD hooks info objects refs
4.新建一个test.txt测试文件
[root@server-1 git]# vim test.txt
123abc
把本地test.txt文件添加到git仓库
[root@server-1 git]# git add test.txt
add后必须执行commit才能真正把文件提交到git仓库里
[root@server-1 git]# git commit -m “add new file test.txt”
*** Please tell me who you are.
Run
git config –global user.email “you@example.com”
git config –global user.name “Your Name”
to set your account’s default identity.
Omit –global to set the identity only in this repository.
fatal: unable to auto-detect email address (got ‘root@server-1.(none)’)
修改test.txt
[root@server-1 git]# vim test.txt
123abc
456789
[root@server-1 git]# git add test.txt
[root@server-1 git]# git commit -m “add new file test.txt”
*** Please tell me who you are.
Run
git config –global user.email “you@example.com”
git config –global user.name “Your Name”
to set your account’s default identity.
Omit –global to set the identity only in this repository.
fatal: unable to auto-detect email address (got ‘root@server-1.(none)’)
报错信息fatal: unable to auto-detect email address (got ‘root@server-1.(none)’)解决办法
编辑vi .git/config ，添加如下参数
[user]
email = root@server-1
name = server-1
报错解决
再次添加和提交test.txt文件
[root@server-1 git]# git add test.txt
[root@server-1 git]# git commit -m “add new file test.txt”
[master (root-commit) 66455b2] add new file test.txt
1 file changed, 2 insertions(+)
create mode 100644 test.txt
查看当前仓库中的状态是否有改动的文件
[root@server-1 git]# git status
# On branch master
# Untracked files:
# (use “git add <file>…” to include in what will be committed)
#
# .test.txt.swp
nothing added to commit but untracked files present (use “git add” to track)
5.查看仓库里面文件版本更新的东西
[root@server-1 git]# git add test.txt
[root@server-1 git]# git commit -m “add new file test.txt”
[master 2654728] add new file test.txt
1 file changed, 3 insertions(+)
[root@server-1 git]# git status
# On branch master
# Untracked files:
# (use “git add <file>…” to include in what will be committed)
#
# .test.txt.swp
nothing added to commit but untracked files present (use “git add” to track)
