linux服务器挂载命令 linux挂载另一台服务器的文件夹

IT技术系统

linux下如何挂载硬盘？1.插入新硬盘 ， 启动Linux服务器 ， 使用fdisk -l 查看硬盘
#fdisk -l
Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes
2.格式化硬盘
#mkfs -t ext4 /dev/sdb
3.挂载硬盘
#mount 硬盘地址 要挂载的地址
#mount /dev/sdb /media/imgs
4.实现系统重启后自动挂载该分区
#vi /etc/fstab
在最后一行添加
/dev/sdb /media/imgs ext4 defaults 1 2
一、添加磁盘
添加加新硬盘重启服务器
添加完之后就可以重启机器了 ， 如果你机器是开启的，进入系统并不能看见你刚添加的那块磁盘，只有等系统重启 ， 重新加载之后才会显示安装的那块磁盘
二、进入系统
使用root用户进入系统
三、 查看硬盘信息
[root@localhost ~]# fdisk -l//磁盘命令

可以看到这台机器加载了三个磁盘sda、sdb、sdc
其中sda是初始磁盘 ， sdb已经初始化且经过使用 ， sdc是刚刚加载的，未格式化的新磁盘
四、创建新硬盘分区
[root@localhost ~]# fdisk /dev/sdc #进入磁盘
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x45a3cadb.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
Command (m for help): m
Command action
atoggle a bootable flag#设定可启动标记
bedit bsd disklabel
ctoggle the dos compatibility flag
ddelete a partition#删除一个分区
llist known partition types#各分区类型所对应的ID
mprint this menu#菜单
nadd a new partition#添加一个分区
ocreate a new empty DOS partition table
pprint the partition table#显示该磁盘下的当前分区信息
qquit without saving changes #不保存退出
screate a new empty Sun disklabel
tchange a partition's system id
uchange display/entry units
vverify the partition table
wwrite table to disk and exit #保存退出
