CentOS 7.1 Bridge啟用STP報錯"Master connection not found or invalid"

標籤：

今天在公司測試Linux bridge搭建，為了使內部docker容器的網路能夠不經過2層封裝轉寄對外公布，顧試用一下bridge功能，結果碰到報錯："Bringing up interface eno16777736:  Error: Connection activation failed: Master connection not found or invalid"

具體錯誤是：

Mar 16 10:56:04 cloud01 systemd[1]: Starting LSB: Bring up/down networking...Mar 16 10:56:05 cloud01 network[876]: Bringing up loopback interface:  Could not load file ‘/etc/sysconfig/network-scripts/ifcfg-lo‘Mar 16 10:56:05 cloud01 network[876]: Could not load file ‘/etc/sysconfig/network-scripts/ifcfg-lo‘Mar 16 10:56:06 cloud01 network[876]: Could not load file ‘/etc/sysconfig/network-scripts/ifcfg-lo‘Mar 16 10:56:06 cloud01 network[876]: Could not load file ‘/etc/sysconfig/network-scripts/ifcfg-lo‘Mar 16 10:56:06 cloud01 network[876]: [  OK  ]Mar 16 10:56:06 cloud01 network[876]: Bringing up interface eno16777736:  Error: Connection activation failed: Master connection not found or invalidMar 16 10:56:06 cloud01 network[876]: [FAILED]Mar 16 10:56:06 cloud01 network[876]: Bringing up interface br0:  Could not load file ‘/etc/sysconfig/network-scripts/ifcfg-br0‘Mar 16 10:56:06 cloud01 network[876]: Could not load file ‘/etc/sysconfig/network-scripts/ifcfg-br0‘Mar 16 10:56:14 cloud01 network[876]: Determining IP information for br0... failed; no link present.

經過一番google，得出答案是得禁用NetworkManager。

執行如下命令：

systemctl stop NetworkManagersystemctl disable NetworkManager

你可以選擇重啟，或者僅單單重啟network服務即可修複。

 

啟用後效果：

# brctl showbridge name     bridge id               STP enabled     interfacesbr0             8000.000c295f4d67       yes             eno16777736
