[root@centos7 ~]# fdisk -l(查看硬盘信息)Disk /dev/sda: 10.7 GB, 10737418240 bytes, 20971520 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x000b5bb9Device BootStartEndBlocksIdSystem /dev/sda1*204841164720480083Linux /dev/sda24116482508799104857682Linux swap / Solaris /dev/sda3250880020971519923136083LinuxDisk /dev/sdb: 213 MB, 213909504 bytes, 417792 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytesDisk /dev/sdc: 213 MB, 213909504 bytes, 417792 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes[root@centos7 ~]# fdisk -l|grep 'sd[a-d]' Disk /dev/sda: 10.7 GB, 10737418240 bytes, 20971520 sectors /dev/sda1*204841164720480083Linux /dev/sda24116482508799104857682Linux swap / Solaris /dev/sda3250880020971519923136083Linux Disk /dev/sdb: 213 MB, 213909504 bytes, 417792 sectors Disk /dev/sdc: 213 MB, 213909504 bytes, 417792 sectors

fdisk:(MBR分区表)支持小于2TB磁盘
parted:(GPT分区表)支持大于2TB磁盘
p: print显示磁盘分区信息
n:new 创建磁盘分区
d:delete 删除
w: 保存并退出

[root@centos7 ~]# fdisk /dev/sdb Welcome to fdisk (util-linux 2.23.2).Changes will remain in memory only, until you decide to write them. Be careful before using the write command.Device does not contain a recognized partition table Building a new DOS disklabel with disk identifier 0x68ff4c51.Command (m for help): p(显示磁盘分区信息)Disk /dev/sdb: 213 MB, 213909504 bytes, 417792 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x68ff4c51Device BootStartEndBlocksIdSystemCommand (m for help): n(创建分区) Partition type: pprimary (0 primary, 0 extended, 4 free) eextended Select (default p): Using default response p Partition number (1-4, default 1): First sector (2048-417791, default 2048): Using default value 2048 Last sector, +sectors or +size{K,M,G} (2048-417791, default 417791): Using default value 417791 Partition 1 of type Linux and of size 203 MiB is setCommand (m for help): w(保存) The partition table has been altered!Calling ioctl() to re-read partition table.

6.创建文件系统(格式化)

[root@centos7 ~]# mkfs.xfs /dev/sdb1 meta-data=https://www.it610.com/dev/sdb1isize=512agcount=4, agsize=12992 blks =sectsz=512attr=2, projid32bit=1 =crc=1finobt=0, sparse=0 data=bsize=4096blocks=51968, imaxpct=25 =sunit=0swidth=0 blks naming=version 2bsize=4096ascii-ci=0 ftype=1 log=internal logbsize=4096blocks=855, version=2 =sectsz=512sunit=0 blks, lazy-count=1 realtime =noneextsz=4096blocks=0, rtextents=0

7.挂载硬盘

[root@centos7 ~]# mkdir -p /data(创建磁盘入口) [root@centos7 ~]# mount /dev/sdb1 /data

8.检查

[root@centos7 ~]# df -h FilesystemSizeUsed Avail Use% Mounted on /dev/sda38.8G1.8G7.0G21% / devtmpfs476M0476M0% /dev tmpfs487M0487M0% /dev/shm tmpfs487M7.7M479M2% /run tmpfs487M0487M0% /sys/fs/cgroup /dev/sda1197M105M93M54% /boot tmpfs98M098M0% /run/user/0 /dev/sdb1200M11M190M6% /data

9.永久挂载 1.mount命令写入到/etc/rc.local(开机自启动)
2.安装规则写入到/etc/fstab

[root@centos7 ~]# blkid(查看设备对应UID) /dev/sda1: UUID="de6cdbf0-7d5a-475a-bb51-cde7e0627e06" TYPE="xfs" /dev/sda2: UUID="0354a10b-4471-4fd4-94ff-d8d802206a31" TYPE="swap" /dev/sda3: UUID="4dad89b5-9401-42d9-9685-0d9093647979" TYPE="xfs" /dev/sdb1: UUID="1e5168bf-a2b1-4d6d-a73b-8e025452116a" TYPE="xfs" /dev/sr0: UUID="2018-11-25-23-54-16-00" LABEL="CentOS 7 x86_64" TYPE="iso9660" PTTYPE="dos" [root@centos7 ~]# vim /etc/fstab# # /etc/fstab # Created by anaconda on Tue Mar 26 15:31:31 2019 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # UUID=4dad89b5-9401-42d9-9685-0d9093647979 /xfsdefaults0 0 UUID=de6cdbf0-7d5a-475a-bb51-cde7e0627e06 /bootxfsdefaults0 0 UUID=0354a10b-4471-4fd4-94ff-d8d802206a31 swapswapdefaults0 0 /dev/sdb1/dataxfsdefaults0 0(第一个0表示备份,第二个0表示检查)检查是否成功挂载 [root@centos7 ~]# umount /data [root@centos7 ~]# df -h FilesystemSizeUsed Avail Use% Mounted on /dev/sda38.8G1.8G7.0G21% / devtmpfs476M0476M0% /dev tmpfs487M0487M0% /dev/shm tmpfs487M7.7M479M2% /run tmpfs487M0487M0% /sys/fs/cgroup /dev/sda1197M105M93M54% /boot tmpfs98M098M0% /run/user/0 [root@centos7 ~]# mount -a(根据/etc/fstab信息挂载所有设备) [root@centos7 ~]# df -h(查看磁盘使用情况) FilesystemSizeUsed Avail Use% Mounted on /dev/sda38.8G1.8G7.0G21% / devtmpfs476M0476M0% /dev tmpfs487M0487M0% /dev/shm tmpfs487M7.7M479M2% /run tmpfs487M0487M0% /sys/fs/cgroup /dev/sda1197M105M93M54% /boot tmpfs98M098M0% /run/user/0 /dev/sdb1200M11M190M6% /data

10.云服务器增加swap(默认是没有的) 查看swap

[root@Centos64 ~]# free -h totalusedfreesharedbuff/cacheavailable Mem:972M140M643M7.7M189M651M Swap:799M0B799M

创建指定大小（500M）的文件

[root@Centos64 ~]# dd if=/dev/zero of=/tmp/500m bs=1M count=500 500+0 records in 500+0 records out 524288000 bytes (524 MB) copied, 1.77195 s, 296 MB/s

if:表示input file,输入文件
of：表示output file,输出文件
bs:表示block size,每次复制多大的文件（块大小）
count:表示次数

[root@Centos64 ~]# cd /tmp [root@Centos64 tmp]# ls 500m ks-script-sqlIbG systemd-private-42cda662aebf4ce4908bed9856d3ba64-chronyd.service-UJTw7B vmware-root_6221-1690178113 yum.log [root@Centos64 tmp]# file 500m 500m: data(数据文件)

将500m改变成swap(格式化)

[root@Centos64 tmp]# mkswap /tmp/500m Setting up swapspace version 1, size = 511996 KiB no label, UUID=c28cdc5c-9618-4788-91c5-1e0d383fe048 [root@Centos64 tmp]# file /tmp/500m /tmp/500m: Linux/i386 swap file (new style), version 1 (4K pages), size 127999 pages, no label, UUID=c28cdc5c-9618-4788-91c5-1e0d383fe048

生效挂载

[root@Centos64 ~]# free -h totalusedfreesharedbuff/cacheavailable Mem:972M140M643M7.7M189M651M Swap:799M0B799M [root@Centos64 tmp]# swapon /tmp/500m swapon: /tmp/500m: insecure permissions 0644, 0600 suggested. [root@Centos64 tmp]# free -h totalusedfreesharedbuff/cacheavailable Mem:972M140M124M7.7M707M643M Swap:1.3G0B1.3G

显示swap的组成

[root@Centos64 tmp]# swapon -s FilenameTypeSizeUsedPriority /dev/sda2partition8191960-2 /tmp/500mfile5119960-3

永久挂载

[root@Centos64 tmp]# vi /etc/fstab# # /etc/fstab # Created by anaconda on Sun Aug4 10:41:10 2019 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info UUID=37253269-2f21-49ad-9621-4e928674487d swapswapdefaults0 0 /tmp/500mswapdefaults0 0

关闭swap后加入的分区：swapoff /tmp/500m

特殊文件系统tmpfs,把数据写入到这个文件系统相当于写入到了内存中，用户读取文件更快

[root@Centos64 tmp]# mount -t tmpfs -o size=500m tmpfs /mem [root@Centos64 tmp]# df -h FilesystemSizeUsed Avail Use% Mounted on /dev/sda39.1G2.0G7.1G22% / devtmpfs476M0476M0% /dev tmpfs487M0487M0% /dev/shm tmpfs487M7.7M479M2% /run tmpfs487M0487M0% /sys/fs/cgroup /dev/sda1197M105M93M54% /boot tmpfs98M098M0% /run/user/0 tmpfs500M0500M0% /mem

-t：指定类型
-o：指定大小

dd还可以测速

[root@Centos64 tmp]# dd if=/dev/zero of=/mem/600m bs=1M count=500 500+0 records in 500+0 records out 524288000 bytes (524 MB) copied, 1.39772 s, 375 MB/s（速度） [root@Centos64 tmp]# dd if=/dev/zero of=/mem/600m bs=1M count=600 dd: error writing ‘/mem/600m’: No space left on device 501+0 records in 500+0 records out 524288000 bytes (524 MB) copied, 0.250703 s, 2.1 GB/s（速度）
