OVS数据库操作

说明

• [Record]就是行对应的_uuid

• [if-exists]当值不存在的是否会报错而不是返回False

基本信息查询

• 列举数据库

# ovsdb-client list-dbs
Open_vSwitch

• 列举数据库表

# ovsdb-client list-tables [DB]

### 列举数据库Open_vSwitch的所有表名
# ovsdb-client list-tables Open_vSwitch
Table
-------------------------
Controller
Bridge
Queue
IPFIX
NetFlow
Open_vSwitch
QoS

# ovs-vsctl --columns=external_ids,iface_types  list Open_vSwitch
external_ids        : {ovn-encap-ip="92.0.0.12", ovn-encap-type="geneve,vxlan", ovn-remote="tcp:92.0.0.11:6642", system-id="c5e8ace3-24c5-4c6e-aed6-f9fc83c0a71e"}

• 查询数据库表项值

# ovs-vsctl [--if-exists] get [Table] [Record] [Column[:Key]]

### 查询Open_vSwitch表对应行的external_ids列的system-id键值
# ovs-vsctl --if-exists get Open_vSwitch 7c18c5c5-f9ad-483d-84bb-5328707b9159  external_ids:system-id
"c5e8ace3-24c5-4c6e-aed6-f9fc83c0a71e"
# ovs-vsctl get open . external-ids:system-id

• 设置数据库表项值

# ovs-vsctl [--if-exists] set [Table] [Record] [Column[:Key]=Value]

### 设置Open_vSwitch表对应行的external_ids列的ovn-encap-type键值
# ovs-vsctl --if-exists set Open_vSwitch 7c18c5c5-f9ad-483d-84bb-5328707b9159  external_ids:ovn-encap-type="geneve"

• 删除数据库表项值

# ovs-vsctl [--if-exists] remove [Table] [Record] [Column] [[Key]=Value]

### 删除Open_vSwitch表对应行的external_ids列的ovn-encap-type键
# ovs-vsctl --if-exists remove Open_vSwitch 7c18c5c5-f9ad-483d-84bb-5328707b9159  external_ids ovn-encap-type="geneve"

• 添加数据库表项

# ovs-vsctl [--if-exists] add [Table] [Record] [Column] [[Key]=Value]

### 为Open_vSwitch表对应行的external_ids列添加ovn-encap-type键（不知道为啥不能添加"geneve,vxlan"）
# ovs-vsctl --if-exists add Open_vSwitch 7c18c5c5-f9ad-483d-84bb-5328707b9159  external_ids ovn-encap-type="geneve"

• 清空数据库表行

# ovs-vsctl [--if-exists] clear [Table] [Record] [Column]

### 为Open_vSwitch表对应行的external_ids列添加ovn-encap-type键（不知道为啥不能添加"geneve,vxlan"）
# ovs-vsctl --if-exists clear Open_vSwitch 7c18c5c5-f9ad-483d-84bb-5328707b9159  external_ids
