git的安装
yum -y install git
进行git的全局配置
git config --global user.name "yourname" #设定自定义的昵称 git config --global user.email "youremail@example.com" #设定自己的邮箱 git config --global color.ui true #设置命令代码多颜色显示 git config --list #列出以上配置的信息
全局配置对应的文件
[liming@centos7 2018-09-21]$ cat ~/.gitconfig [user] name = liming email = liming@centos7.com [color] ui = true
新建项目目录并初始化
mkdir 2018-09-21 cd 2018-09-21 git init . 在当前目录初始化，之后会出现目录 .git
局部配置用户的相关信息
[liming@centos7 2018-09-21]$ git config user.name 'liming_local' [liming@centos7 2018-09-21]$ cat .git/config #其对应的文件 [core] repositoryformatversion = 0 filemode = true bare = false logallrefupdates = true [user] name = liming_local
git status命令：查看当前用户的提交状态
git log 命令：查看用户操作的记录
git add命令，添加到待提交列表里面
首先：我们来新建两个文件 readme 和 log 然后使用 git add提交 [liming@centos7 2018-09-21]$ git add readme [liming@centos7 2018-09-21]$ git add log 其次：提交改变并查看状态 [liming@centos7 2018-09-21]$ git commit -m "初始化提交" [master (root-commit) 04018e4] 初始化提交 2 files changed, 2 insertions(+) create mode 100644 log create mode 100644 readme [liming@centos7 2018-09-21]$ git status # On branch master nothing to commit, working directory clean 再其次：在文件readme中加入一行，并查看状态 [liming@centos7 2018-09-21]$ vim readme [liming@centos7 2018-09-21]$ git status # On branch master # Changes not staged for commit: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: readme # no changes added to commit (use "git add" and/or "git commit -a")
好，我们先将它提交
[liming@centos7 2018-09-21]$ git add readme
[liming@centos7 2018-09-21]$ git status
# On branch master
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
#
# modified: readme
#
[liming@centos7 2018-09-21]$ git commit -m "增加一行readme"
[master 5eb920f] 增加一行readme
1 file changed, 1 insertion(+)
查看log，里面没有中文显示

.gitignore文件：用来忽略一些不想提交的文件,这个最好初始化的时候创建
首先建立一个文件 touch .gitignore touch database.yml #忽略这个文件 vim .gitignore *yml 忽略yml结尾的文件 提交.gitignore git add .gitignore git commit -m '提交文件 .gitignore'
git checkout 分支名称， 切换到其他分支的命令
[liming@centos7 2018-09-21]$ git branch * master [liming@centos7 2018-09-21]$ git branch 20180921-001 #创建分支 [liming@centos7 2018-09-21]$ git branch #当前分支前面有* 20180921-001 * master [liming@centos7 2018-09-21]$ git checkout 20180921-001 #切换到分支上面 Switched to branch '20180921-001'
接着我们修改文件readme
再提交
git add readme
git commit -m '001分支修改readme内容'
查看
分别切换到主分支，和001分支，发现001分支多一条log
删除一个分支：git branch -d 名称
[liming@centos7 2018-09-21]$ git branch 20180921-002 [liming@centos7 2018-09-21]$ git branch -d 20180921-002 Deleted branch 20180921-002 (was a4f1c8b). [liming@centos7 2018-09-21]$ git branch * 20180921-001 master
git merge 分支名称 将分支的改变同步到主分支，这个比svn和cvs有优势，没有奔溃的危险
先切换到主分支 git checkout master 合并 git merge 20180921-001 git log #查看 日志多了分支的一条记录，id 也一样
到这里为止，我们只用到了本地仓库的层次，还有远程的git服务器用来提交代码，然后成员之间相互交流
先说一下现有的git服务器，有githup这个是外国的，要考虑网络问题还有私有是要收费的，codIng.net这个是国内的，私有是免费的
现在我们使用coding.net说明
1 先在coding.net上面注册 2 新建项目 3 回到linux上面推送代码 [liming@centos7 2018-09-21]$ git remote add origin https://git.coding.net/study_more/first_item.git [liming@centos7 2018-09-21]$ git push -u origin master Username for 'https://git.coding.net': XXXXX Password for 'https://study_more@git.coding.net': Counting objects: 17, done. Compressing objects: 100% (12/12), done. Writing objects: 100% (17/17), 1.51 KiB | 0 bytes/s, done. Total 17 (delta 2), reused 0 (delta 0) To https://git.coding.net/study_more/first_item.git * [new branch] master -> master Branch master set up to track remote branch master from origin.
回到coding.net上面查看
当然也可以多个远程服务器的地址并存：
修改配置
cat .git/config [remote "origin"] url = https://git.coding.net/study_more/first_item.git fetch = +refs/heads/*:refs/remotes/origin/* [remote "backup"] url =比如说github的地址 fetch = +refs/heads/*:refs/remotes/bakcup/*
说明：
git remote add origin https://git.coding.net/study_more/first_item.git 其中的origin指的就是 远程服务其的名称
git push -u origin master （master:master）
git clone 从远程下载git的项目
1 新建一个目录，可以是没有使用git初始化的 [liming@centos7 2018-09-21]$ cd .. [liming@centos7 workspace]$ ls 2018-09-21 [liming@centos7 workspace]$ mkdir down_load [liming@centos7 workspace]$ cd down_load/ [liming@centos7 down_load]$ git clone https://git.coding.net/study_more/first_item.git Cloning into 'first_item'... Username for 'https://git.coding.net': XXXXXX Password for 'https://study_more@git.coding.net': remote: Enumerating objects: 17, done. remote: Counting objects: 100% (17/17), done. remote: Compressing objects: 100% (12/12), done. remote: Total 17 (delta 2), reused 0 (delta 0) Unpacking objects: 100% (17/17), done. [liming@centos7 down_load]$ ls first_item
git pull origin master 从远程服务器上面pull项目，必须是使用了git初始化了的情况
这样一来，一个提交，一个pull就可以相互的交流了，工作中要多push
git冲突的问题：
场景：我这边修改了本地文件没提交，另外一边有另外一个同事也修改了同样的文件并且提交了
我push命令的时候出现了错误：
[liming@centos7 2018-09-21]$ git pull origin master Username for 'https://git.coding.net': study_more Password for 'https://study_more@git.coding.net': remote: Enumerating objects: 5, done. remote: Counting objects: 100% (5/5), done. remote: Compressing objects: 100% (3/3), done. remote: Total 3 (delta 1), reused 0 (delta 0) Unpacking objects: 100% (3/3), done. From https://git.coding.net/study_more/first_item * branch master -> FETCH_HEAD Auto-merging readme CONFLICT (content): Merge conflict in readme Automatic merge failed; fix conflicts and then commit the result. [liming@centos7 2018-09-21]$ git status # On branch master # Your branch is ahead of 'origin/master' by 1 commit. # (use "git push" to publish your local commits) # # You have unmerged paths. # (fix conflicts and run "git commit") # # Unmerged paths: # (use "git add <file>..." to mark resolution) # # both modified: readme # no changes added to commit (use "git add" and/or "git commit -a")
解决：注意上面提到了readme文件
首先 人工去协商；确认需要保留的
this is a first file for git add a line 在001分支上面加的内容 <<<<<<< HEAD 在目录2018-09-21中的修改 ======= 在目录hhh中的修改 >>>>>>> 83f9fe1b6ee0bf33b70deda90d40043fba2084b8 我将上面的内容改为
this is a first file for git
add a line
在001分支上面加的内容
在目录2018-09-21中的修改
我再操作一次
git add readme
git commit -m "合并冲突"
git push origin master
在同事的另外一般就可以pull了看到的就是合并后的内容
注意事项：
首先想到的是要pull代码，修改代码要多提交，一旦出现冲突就可以短时间内解决，否则一旦代码多了，你哭去吧
最后git使用注意的事项
1 不要改变时间线 rebase不要用，cherry-pick没必要用
2 代码存放选择：开源放 github ,私有放coding.net ,尽量不要自己搭建gitlab,出了问题不好解决
3 git log写具体些，宁多勿少
