一、查詢存儲(chǔ)設(shè)備的UUID
1、使用blkid命令查看
（1）查詢所有存儲(chǔ)設(shè)備的UUID：blkid彬向。
（2）查詢指定設(shè)備的UUID：blkid /dev/sda5。
# blkid
/dev/sda1: UUID="9ADAAB4DDAAB250B" TYPE="ntfs"
/dev/sdb1: UUID="B2FCDCFBFCDCBAB5" TYPE="ntfs"
/dev/sdb5: UUID="46FC5C74FC5C5FEB" TYPE="ntfs"
/dev/sdb6: TYPE="swap" UUID="2cec6109-5bcf-45a3-ba1b-978b041c037f"
/dev/sdb8: UUID="9ee6f22d-b394-422c-9b4a-1525a3220942" SEC_TYPE="ext2" TYPE="ext3"
/dev/sdb7: UUID="4bcb9381-6e25-4304-8743-f882039ff3ad" TYPE="ext3"
2稼锅、使用vol_id查看
vol_id /dev/sda1
ID_FS_USAGE=filesystem
ID_FS_TYPE=reiserfs
ID_FS_VERSION=3.6
ID_FS_UUID=be6d8295-a1c4-48e9-b68d-f4b043cd5f2c
ID_FS_UUID_ENC=be6d8295-a1c4-48e9-b68d-f4b043cd5f2c
ID_FS_LABEL=
ID_FS_LABEL_ENC=
ID_FS_LABEL_SAFE=
3幢哨、查看by_uuid目錄
ls -l /dev/disk/by-uuid
lrwxrwxrwx 1 root root 10 2008-05-15 22:37 2cec6109-5bcf-45a3-ba1b-978b041c037f -> ../../sdb6
lrwxrwxrwx 1 root root 10 2008-05-15 22:37 46FC5C74FC5C5FEB -> ../../sdb5
lrwxrwxrwx 1 root root 10 2008-05-15 22:37 4bcb9381-6e25-4304-8743-f882039ff3ad -> ../../sdb7
lrwxrwxrwx 1 root root 10 2008-05-15 22:37 9ee6f22d-b394-422c-9b4a-1525a3220942 -> ../../sdb8
二、查詢網(wǎng)卡的UUID
1、使用nmcli命令查詢
（1）安裝NetworkManager依賴包：yum -y install NetworkManager
（2）啟動(dòng)NetworkManager服務(wù)：service NetworkManager start
（3）查看網(wǎng)卡的UUID：nmcli con
2楼熄、查看/etc/sysconfig/network-scripts/ifcfg-eth0文件查詢UUID
通過查看/etc/sysconfig/network-scripts/ifcfg-eth0文件查詢UUID忆绰，只有當(dāng)ifcfg-eth0文件能正常查看時(shí)才有效。
cat /etc/sysconfig/network-scripts/ifcfg-eth0 | grep UUID
