centos-stream9系统配置网卡bond接口方法

admin

首先从目录切换到网卡目录：

# cd /etc/NetworkManager/system-connections/

修改要做bond的网卡：
; ~2 r7 \7 T6 u) {& z
9 z2 V& f% N+ i, l; F6 c#vim ens160.nmconnection
3 x2 s. F0 x3 s8 k( R& ^! K! |, i2 y[connection]

$ K1 M  ~. w+ C/ L3 Rmethod=auto

配置bond文件：

' m" V& Y( s8 `: o( R5 k8 u
# T5 G- a) h# ?/ Y. @! o) k; p# cat bond0.nmconnection
[connection]
id=bond0

即可

还需要注意的是：
9 `1 {  p; V7 H/ k! S9 m-rw-------. 1 root root 204 Nov 30 11:14 bond_mgt.nmconnection
2 J8 T+ M3 b3 l  T! u0 m 权限是600

所以需要chmod 600 bond_mgt.nmconnection
; b2 a  b; q! d# }* t2 ]3 x
, @, \" V6 v* T! u3 r; _. m7 ~) C. O否则启动网卡会失败。权限太高不能正常启动网卡配置文件。
