服务器配置docker&硬盘格式化

{ "registry-mirrors": [ "http://58f8b602.m.daocloud.io" ], "insecure-registries": ["docker.umiit.cn:5043"] } docker login -u 'umiit' -p '***' docker.umiit.cn:5043 

vim ~/.bash_profile export PS1="[\u@`/sbin/ifconfig eth0 | sed -nr 's/.*inet (addr:)?(([0-9]*\.){3}[0-9]*).*/\2/p'` \W centerServer! ]\$ " 

先购买一个云盘 500G大小

查看是否有一个 /dev/xvdb 或者 数据盘大小与你要挂载一致的硬盘

fdisk /dev/xvdb ；对数据盘进行分区；根据提示，依次输入“n”，“p”“1”，两次回车，“wq”，分区就开始了，很快就会完成。

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel with disk identifier 0x5c273d61. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable.

fdisk -l 查看新的分区。新分区 xvdb1 已经创建好。如下面示例中的/dev/xvdb1

• 你这个数据盘是新购买的，以前没有用过（没有存储过数据），那么就要对其进行格式化，使用 mkfs.ext3 /dev/xvdb1命令。
• 第二种，如果你之前就有数据盘，只是你把系统盘重置了，需要将数据盘再次挂载到重置后的系统上，那么就不要对其格式化（跳过此步骤），直接执行后面的步骤挂载就可以了。

前提是你已经创建了这个目录（创建目录的命令是mkdir）。以下命令写入新分区信息

echo '/dev/xvdb1 /mnt ext3 defaults 0 0' >> /etc/fstab

查看，出现以下信息就表示写入成功。

cat /etc/fstab UUID=af414ad8-9936-46cd-b074-528854656fcd / ext4 errors=remount-ro 0 1 /dev/xvdb /mnt ext3 defaults 0 0

使用mount -a挂载，df -h命令查看，出现以下信息就说明挂载成功，可以开始使用新的分区了。

df -h Filesystem Size Used Avail Use% Mounted on /dev/xvda1 20G 1.3G 18G 7% / none 4.0K 0 4.0K 0% /sys/fs/cgroup udev 2.0G 4.0K 2.0G 1% /dev tmpfs 396M 372K 395M 1% /run none 5.0M 0 5.0M 0% /run/lock none 2.0G 0 2.0G 0% /run/shm none 100M 0 100M 0% /run/user /dev/xvdb 99G 60M 94G 1% /mnt
