~]# yum -y install postfix
~]# sed -i 's/inet_interfaces = localhost/inet_interfaces = all/g' /etc/postfix/main.cf
~]# systemctl start postfix
~]# systemctl restart postfix

配置gitlab-ce yum源并安装

~]# 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 clean all
~]# yum makecache

git 客户端常用命令

# git config --global user.name "name" #设置全局用户名
# git config --global user.email  xxx@novogene.com # 设置全局邮箱
# git config --global --list #列出用户全局设置
# git add index.html / . #添加指定文件、目录或当前目录下所有数据到暂存区
# git commit -m "xx" #提交文件到工作区
# git status #查看工作区的状态
# git push #提交代码到服务器
# git pull # 获取代码到本地
# git log # 查看操作日志
# vim .gitignore  # 定义忽略文件
# git rest --hard HEAD^^ # git版本回滚，HEAD为当前版本，加一个^为上一个，^^为上上一个版本
# git reflog # 获取每次提交的ID,可以使用--hard根据提交的ID进行版本回退
# git reset --hard 5ae4b06 #回退到指定id的版本
# git branch # 查看当前所处的分支
# git checkout -b develop # 创建并切换到一个新分支
# git checkout  develop #切换分支

git缓存区与工作区等概念

工作区: clone 的代码或者开发自己编写的代码文件所在的目录，通常是代码所在的一个服务的目录名称;

暂存区: 用于存储在工作区中对代码进行修改后的文件所保存的地方，使用git add添加;
本地仓库: 用于提交存储在工作区和暂存区中改过的文件地方，使用git commit提交;
远程仓库: 多个开发共同协作提交代码的仓库，即gitlab或github服务器。
