# 分区：输入 n, p, 1, w
fdisk /dev/vdb
# n add a new partition
# p primary (0 primary, 0 extended, 4 free)
# 1 分区号 (1-4，默认 1)
# w write table to disk and exit

rc.local 需要可执行权限才会被执行：
chmod +x /etc/rc.d/rc.local示例内容：
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
touch /var/lock/subsys/local
mount /dev/vdb1 /data

ulimit -n 65535官方建议在 systemd 环境下改用自定义 service 或 udev 规则；
rc.local因并行启动，不保证在其他服务之后运行。
