linux查询网络uuid,【山外问道】Linux UUID的查询方法

本文打印版下载地址

一、查询存储设备的UUID

1、使用blkid命令查看

(1)查询所有存储设备的UUID：blkid。

(2)查询指定设备的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、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、查看by_uuid目录

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、查询网卡的UUID

1、使用nmcli命令查询

(1)安装NetworkManager依赖包：yum -y install NetworkManager

(2)启动NetworkManager服务：service NetworkManager start

(3)查看网卡的UUID：nmcli con

2、查看/etc/sysconfig/network-scripts/ifcfg-eth0文件查询UUID

通过查看/etc/sysconfig/network-scripts/ifcfg-eth0文件查询UUID，只有当ifcfg-eth0文件能正常查看时才有效。

cat /etc/sysconfig/network-scripts/ifcfg-eth0 | grep UUID
