有很多小白在配置后静态Ip之后, TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=ens160 DEVICE=ens160 ONBOOT=yes IPADDR=192.168.135.145 NETMASK=255.255.255.0 GATEWAY=192.168.135.2 DNS1=114.114.114.114过段时间重启就会发现网络无法连接,静态Ip失效; 查看ip addr 时是这个给样子的 [zzy@localhost ~]$ ip addr 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 forever 2: ens160: mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 00:0c:29:68:c8:16 brd ff:ff:ff:ff:ff:ff 3: virbr0: mtu 1500 qdisc noqueue state DOWN group default qlen 1000 link/ether 52:54:00:af:c1:75 brd ff:ff:ff:ff:ff:ff inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0 valid_lft forever preferred_lft forever 4: virbr0-nic: mtu 1500 qdisc fq_codel master virbr0 state DOWN group default qlen 1000 link/ether 52:54:00:af:c1:75 brd ff:ff:ff:ff:ff:ff这个时候可以查看一下网卡链接状态,有可能在这之前你需要先开启一下网络管理服务 systemctl start NetworkManager 或者 systemctl restart NetworkManager 然后查看网卡服务状态----- [zzy@localhost ~]$ nmcli device DEVICE TYPE STATE CONNECTION virbr0 bridge unmanaged -- ens160 ethernet unmanaged -- lo loopback unmanaged -- virbr0-nic tun unmanaged --都处于未管理状态–此时将管理服务打开 确认一下网卡管理状态—>> nmcli n disabled开启网卡管理状态 nmcli n on 再次查看网卡管理状态 nmcli n enabled nmcli device DEVICE TYPE STATE CONNECTION ens160 ethernet connected ens160 virbr0 bridge unmanaged -- lo loopback unmanaged -- virbr0-nic tun unmanaged --ip addr 查看ip [zzy@localhost ~]$ ip addr 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 forever 2: ens160: mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:0c:29:68:c8:16 brd ff:ff:ff:ff:ff:ff inet 192.168.135.145/24 brd 192.168.135.255 scope global noprefixroute ens160 valid_lft forever preferred_lft forever inet6 fe80::f1ff:ba15:28b7:8b3a/64 scope link noprefixroute valid_lft forever preferred_lft forever 3: virbr0: mtu 1500 qdisc noqueue state DOWN group default qlen 1000 link/ether 52:54:00:af:c1:75 brd ff:ff:ff:ff:ff:ff 4: virbr0-nic: mtu 1500 qdisc fq_codel state DOWN group default qlen 1000 link/ether 52:54:00:af:c1:75 brd ff:ff:ff:ff:ff:ff |
