为什么我的云服务器无法获取 IP 地址?
山河官方提供的 Linux 映像使用 NetworkManager 来自动化云服务器的网络配置, 其默认配置是通过 DHCP 方式来获取 IP 地址,你需要保证 NetworkManager 相关的 daemon 正常运行。 如果工作不正常,你可以手动重启:
RHEL/CentOS
# service NetworkManager restart
Fedora
# systemctl restart NetworkManager
Debian
# service network-manager restart
Ubuntu
# service network-manager restart
必要时,你可能需要重启 messagebus daemon 后才能正常启动 NetworkManager:
RHEL/CentOS
# service messagebus restart
# service NetworkManager restart
Fedora
# systemctl restart messagebus
# systemctl restart NetworkManager
Debian
# service messagebus restart
# service network-manager restart
Ubuntu
# service dbus restart
# service network-manager restart
