在Rocky9中，丢弃使用了传统的network 而使用新的NetworkManager管理方式
所有较之前的版本配置方式有所不同
先查看下未配置前现在的ip参数
[root@localhost ~]# ip a1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever2: ens160: mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:0c:29:bb:06:6b brd ff:ff:ff:ff:ff:ff altname enp3s0 inet 192.168.252.151/24 brd 192.168.252.255 scope global dynamic noprefixroute ens160 valid_lft 1731sec preferred_lft 1731sec inet6 fe80::20c:29ff:febb:66b/64 scope link noprefixroute valid_lft forever preferred_lft forever 可以看到现在是dhcp获取的192.168.252.151
现在配置一下静态：
root@localhost ~]# vim /etc/NetworkManager/system-connections/ens160.nmconnection[connection]id=ens160uuid=dd894cca-3086-3461-9acf-97d7cc6a8188type=ethernetautoconnect-priority=-999interface-name=ens160timestamp=1668700728[ethernet][ipv4]method=auto //自动获取[ipv6]addr-gen-mode=eui64method=auto[proxy]更改 [ipv4] 那段：
[connection]id=ens160uuid=dd894cca-3086-3461-9acf-97d7cc6a8188type=ethernetautoconnect-priority=-999interface-name=ens160timestamp=1668700728[ethernet][ipv4]address1=192.168.1.1/24,192.168.1.254 //添加ip/子网掩码,网关dns=192.168.1.1 //添加dns地址（多个用;隔开）method=manual[ipv6]addr-gen-mode=eui64method=auto[proxy]更改完成后保存退出
接下来写入配置文件
[root@localhost ~]# nmcli c reload再更新一下网卡配置
[root@localhost ~]# nmcli c up ens160 Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/6)静态ip已配置完成啦
再查看下现在的tcp/ip参数
[root@localhost ~]# ip a 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever2: ens160: mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:0c:29:bb:06:6b brd ff:ff:ff:ff:ff:ff altname enp3s0 inet 192.168.1.1/24 brd 192.168.1.255 scope global noprefixroute ens160 valid_lft forever preferred_lft forever inet6 fe80::20c:29ff:febb:66b/64 scope link noprefixroute valid_lft forever preferred_lft forever 可以看到现在未静态配置的192.168.1.1
再查看一下dns地址
[root@localhost ~]# cat /etc/resolv.conf # Generated by NetworkManagernameserver 192.168.1.1可以看到均和上面配置的参数一致
整个就配置完成了
