5.磁盘分区(启动Linux)
[root@centos7 ~]# fdisk -l(查看硬盘信息)

[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.

[root@centos7 ~]# ll /dev/sdb*
brw-rw---- 1 root disk 8, 16 Aug 3 22:44 /dev/sdb
brw-rw---- 1 root disk 8, 17 Aug 3 22:44 /dev/sdb1
6.创建文件系统(格式化)
[root@centos7 ~]# mkfs.xfs /dev/sdb1
meta-data=/dev/sdb1 isize=512 agcount=4, agsize=12992 blks
= sectsz=512 attr=2, projid32bit=1
= crc=1 finobt=0, sparse=0
data = bsize=4096 blocks=51968, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0 ftype=1
log =internal log bsize=4096 blocks=855, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=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
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 8.8G 1.8G 7.0G 21% /
devtmpfs 476M 0 476M 0% /dev
tmpfs 487M 0 487M 0% /dev/shm
tmpfs 487M 7.7M 479M 2% /run
tmpfs 487M 0 487M 0% /sys/fs/cgroup
/dev/sda1 197M 105M 93M 54% /boot
tmpfs 98M 0 98M 0% /run/user/0
/dev/sdb1 200M 11M 190M 6% /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)

检查是否成功挂载
[root@centos7 ~]# umount /data

10.云服务器增加swap(默认是没有的)
查看swap
[root@Centos64 ~]# free -h
total used free shared buff/cache available
Mem: 972M 140M 643M 7.7M 189M 651M
Swap: 799M 0B 799M
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
total used free shared buff/cache available
Mem: 972M 140M 643M 7.7M 189M 651M
Swap: 799M 0B 799M
[root@Centos64 tmp]# swapon /tmp/500m
swapon: /tmp/500m: insecure permissions 0644, 0600 suggested.
[root@Centos64 tmp]# free -h
total used free shared buff/cache available
Mem: 972M 140M 124M 7.7M 707M 643M

显示swap的组成
[root@Centos64 tmp]# swapon -s
Filename Type Size Used Priority
/dev/sda2 partition 819196 0 -2
/tmp/500m file 511996 0 -3
永久挂载
[root@Centos64 tmp]# vi /etc/fstab
#

UUID=37253269-2f21-49ad-9621-4e928674487d swap swap defaults 0 0
/tmp/500m swap defaults 0 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
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 9.1G 2.0G 7.1G 22% /
devtmpfs 476M 0 476M 0% /dev
tmpfs 487M 0 487M 0% /dev/shm
tmpfs 487M 7.7M 479M 2% /run
tmpfs 487M 0 487M 0% /sys/fs/cgroup
/dev/sda1 197M 105M 93M 54% /boot
tmpfs 98M 0 98M 0% /run/user/0
tmpfs 500M 0 500M 0% /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）
永久生效
