#Centos
        visudo运行普通用户$(whomai)执行sudo操作
       
        http://www.cnblogs.com/xianyunhe/archive/2011/08/08/2124342.html
        在/etc/gdm/custom.conf文件中添加以下内容
        [daemon]
        AutomaticLogin=username
        AutomaticLoginEnable=True
       
#virtualbox Guest Host目录共享
        sudo usermod -a -G vboxsf $(whomai)

#yum源镜像
        1、备份
        mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
        2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/
        CentOS 5
        wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
        CentOS 6
        wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
        CentOS 7
        wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
        3、之后运行yum makecache生成缓存

　　mysql的安装

　　yum install mariadb-server.x86_64 mariadb.x86_64
  　　systemctl enable mariadb.service

　　 systemctl start mariadb.service

#docker的安装
        http://git.oschina.net/wushifeng/hivedocker/blob/master/ready.sh
        #!/usr/bin/env bash
        #1 centos上安装docker
        if [ -f /usr/bin/docker ]; then
            echo 'docker installed'
        else
            sudo yum install docker.x86_64
            docker -h

sudo systemctl enable docker.service
        fi

#2 docker的仓库镜像的国内站点
        https://www.daocloud.io/mirror#accelerator-doc
        http://guide.daocloud.io/dcs/daocloud-9153151.html

#https://yq.aliyun.com/articles/29941
        #Docker 镜像加速器
        #docker version <=1.10
        :<<EOF
        sudo cp -n /lib/systemd/system/docker.service /etc/systemd/system/docker.service
        sudo sed -i "s|ExecStart=/usr/bin/docker daemon|ExecStart=/usr/bin/docker daemon --registry-mirror=<your accelerate address>|g" /etc/systemd/system/docker.service
        sudo systemctl daemon-reload
        sudo service docker restart
        EOF

#docker version >1.10
        sudo mkdir -p /etc/docker
        sudo tee /etc/docker/daemon.json <<-'EOF'
        {
          "registry-mirrors": ["https://2mt5bmc8.mirror.aliyuncs.com"]
        }
        EOF
        sudo systemctl daemon-reload
        sudo systemctl restart docker

#3 普通用户使用dcoker
        #普通的用户直接使用docker命令运行 [设置完成后，注销用户重新登陆]
        sudo groupadd docker
        sudo gpasswd -a $(whomai) docker
        sudo systemctl restart docker

　　docker debian source

默认
deb http://deb.debian.org/debian wheezy main
deb http://deb.debian.org/debian wheezy-updates main
deb http://security.debian.org wheezy/updates main

使用163的源
echo "deb http://mirrors.163.com/debian wheezy main non-free contrib" >/etc/apt/sources.list
echo "deb http://mirrors.163.com/debian wheezy-proposed-updates main contrib non-free" >>/etc/apt/sources.list
echo "deb http://mirrors.163.com/debian wheezy-updates main contrib non-free" >>/etc/apt/sources.list
echo "deb http://mirrors.163.com/debian-security wheezy/updates main contrib non-free " >>/etc/apt/sources.list
echo "deb http://http.us.debian.org/debian wheezy main contrib non-free" >>/etc/apt/sources.list
echo "deb http://security.debian.org wheezy/updates main contrib non-free" >>/etc/apt/sources.list
