开机自动挂载新分区的方法

方法一：

1. 查看UUID（Linux中硬件的唯一标识符） 

[root@localhost /]# blkid /dev/sdb1 
/dev/sdb1: UUID="043b89a0-b542-49b9-a383-a86294454123" TYPE="ext4" 

2. 将挂载参数写入Linux 中 /dev/fstab 文件 

[root@localhost dev]# echo "UUID="043b89a0-b542-49b9-a383-a86294454123" /data" >> /dev/fstab

3. mount -a 命令（读取fstab 文件中的参数）直接挂载

[root@localhost dev]# mount -a

方法二（推荐）：

将挂载的命令写入文件开机启动文件/etc/rc.local

[root@localhost dev]# vim /etc/rc.local 

#!/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.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# 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 UUID="043b89a0-b542-49b9-a383-a86294454123" /data
