linux 新增硬盘分区并挂载

运行fdisk -l 查看计算机对应的硬盘信息

运行df -TH查看硬盘与持载关联关系

fdisk /dev/vdb 进入硬盘

n :创建分区 （h查看帮助）

mkfs -t ext3 -c /dev/sdb6 格式化硬盘

重启后自动挂载

root@v-wdvwzli8s6e:~# vim /etc/fstab

/dev/sdb5 /hyxSoftware/fast/web ext3 defaults 1 2
/dev/sdb6 /hyxSoftware/fast/db ext3 defaults 1 2

 

如果想每次系统重启都能自动挂载该分区可修改/etc/fstab文件，在最后加一段 /dev/sdb1    /www    ext3    defaults 1 2 (格式说明：/dev/sdb1 代表哪个分区  ext3是该分区的格式 defaults 是挂载时所要设定的参数(只读，读写，启用quota等)，输入defaults包括的参数有(rw、dev、exec、auto、nouser、async) ，1是使用dump是否要记录，0是不要。 2是开机时检查的顺序，是boot系统文件就为1，其他文件系统都为2，如不要检查就为0)

 reboot 重启服务器
