parted

输入parted命令进入part分区工具，可以看到行前面有（parted）提示，输入help命令可以看到工具命令列表，输入print all可以查看当前磁盘情况

## 需要获取 root权限才能执行 $ parted WARNING: You are not superuser.  Watch out for permissions. /dev/mapper/control: open failed: Permission denied Failure to communicate with kernel device-mapper driver. Incompatible libdevmapper (unknown version) and kernel driver (unknown version). Error: No device found Retry/Cancel?

$ sudo parted GNU Parted 3.2 Using /dev/sda Welcome to GNU Parted! Type help to view a list of commands.

1.   parted硬盘分区 方式一

方式一：要对第二块磁盘进行分区，首先选中它，select  /dev/sdb,然后选择分区方法为gpt：mklable gpt。输入mkpart开始分区，按提示输入分区名称disk1，选择分区文件类型，默认为ext2，输入分区开始地址1，结束地址2048，这里单位是M。分区成功，开始地址如果是0，系统会提示不满足4k对齐要求，无法达到最佳性能

$ sudo parted GNU Parted 3.2 Using /dev/sda Welcome to GNU Parted! Type help to view a list of commands. ## 选择硬盘 (parted) select /dev/sda Using /dev/sda ## 分区方法 (parted) mklabel gpt                                                      (parted) mkpart    ## PARTLABEL 对应的名称                                                         Partition name?  []? 1                                                    File system type?  [ext2]? ext4                                           Start?                                                                    Start? 1                                                                  End? 10240 (parted)

2.   parted硬盘分区 方式二

方式二：也可以使用命令行进行分区：mkpart 分区名 起始位置 结束位置

$ sudo parted GNU Parted 3.2 Using /dev/sda Welcome to GNU Parted! Type help to view a list of commands. (parted) select /dev/sda Using /dev/sda (parted) mkpart 2 10240 20480

3.   分区查看

可以用print命令看到已经分好了两块分区

(parted) print                                                            Model: VMware, VMware Virtual S (scsi) Disk /dev/sda: 64.4GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: ## 这边 2 分区虽然没有 File system，不要紧张，后期可以自己格式化嘛 Number  Start   End     Size    File system  Name  Flags  1      1049kB  10.2GB  10.2GB  ext4         1  2      10.2GB  20.5GB  10.2GB               2 ## 退出、自动保存分区信息 (parted) quit                                                             Information: You may need to update /etc/fstab.

4.   格式化、挂载

这里简单介绍一下，不详细介绍格式化、挂载操作了

## 格式化:方式很多，不详细介绍 mkfs.ext4 /dev/sda2 ## 挂载：开机自动挂载这边也暂时不详细介绍了 mount /dev/sda2 /tmp
