# 更改docker数据目录 因为ssd盘小要迁移/lib/docker当安装完成docker后执行如下
1 开机挂载数据盘
    fdisk -l
    mkfs.ext4 /dev/sdXXXX  
    mkdir -p /data
    blkid
    vim fstab
    UUID=xxxxxx  /data ext4 defaults 0 0 
    mount -a
2 迁移docker-datadir到/data/docker
    systemctl stop docker
    cd /var/lib/docker
    mv docker /data/
    ln -s /data/docker docker
    ll docker
3 重启docker
    systemctl enable docker
    systemctl start docker

# linux系统修改时区，时间自动同步
  1、调整时区
    cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
  2、手动调整时间(需要ntpdate)
    yum install -y ntpdate
    ntpdate us.pool.ntp.org
  3、加入定时计划任务，每天进行同步一次：
    cd /etc/cron.daily
    vim ntpdateup.sh
#! /bin/bash
/usr/sbin/ntpdate -s us.pool.ntp.org &> /dev/null
/usr/sbin/hwclock --systohc &> /dev/null

# 提取IP地址：
    1 ifconfig eth0 | grep "inet addr" | awk '{print $2}' | tr -d "addr:"         
    2 ifconfig eth0 |grep 'inet addr:'|sed 's/.*addr://'|sed 's/\([B|M]\).*//'     
    3 ifconfig eth0 | sed -n '2p' | awk '{print $2}' | tr -d "addr:"   
    4 ifconfig eth0 | sed -n 2p  | sed 's/^.*addr://g' | sed 's/Bcast.*$//g'
