NetworkManagerを削除した後にNetwork.serviceを起動できません。

tag-icon • tag-icon centos networking networkmanager
NetworkManagerを削除した後にNetwork.serviceを起動できません。

この問題がありますが、インターネット上で解決策が見つかりません。 cpanelとwhmを含むcentos 7サーバーがあります。 NetworkManagerをアンインストールしてnetwork.serviceを開きたいです。これにより、常に次のエラーが発生します。

Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.

答え1

NetworkManagerが実際に無効になっていることを確認できます。

# nmcli device status

# systemctl list-unit-files | grep NetworkManager

次に、そのファイルを編集してインターフェイスでNMパラメータを確認する必要があります。

Centosはネットワークデバイスの一貫した命名を使用しているため、ethXが表示されていなくても驚かないでください。

構成ファイルの入力

# /etc/sysconfig/network-scripts/ifcfg-enpXsX

そして以下を入力してください：

NM_CONTROLLED="no"

DHCPを使用しようとしていることが確認されました。静的IPアドレスを試してください。

例:

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
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
UUID=666666666645664654654654
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.125.10
PREFIX=24
GATEWAY=192.168.125.1
DNS1=192.168.125.48
DNS2=8.8.8.8
IPV6_PRIVACY=no
NM_CONTROLLED=no

DNSを設定するには、/etc/resolv.confファイルを変更する必要があります。

その後、ネットワークサービスを再起動して有効にしてみてください。

systemctl restart network    
systemctl enable network
