我试图部署RDO，但不能遵循它的一些先决条件 ：
如果您的系统使用NetworkManager运行，则需要禁用它。
停止并禁用NetworkManager：
systemctl stop NetworkManager systemctl disable NetworkManager systemctl enable network
我可以按照前两个命令没有问题。 但是，第三个人给了我一个我不明白的回答：
#systemctl enable network network.service is not a native service, redirecting to /sbin/chkconfig. Executing /sbin/chkconfig network on The unit files have no [Install] section. They are not meant to be enabled using systemctl. Possible reasons for having this kind of units are: 1) A unit may be statically enabled by being symlinked from another unit's .wants/ or .requires/ directory. 2) A unit's purpose may be to act as a helper for some other unit which has a requirement dependency on it. 3) A unit may be started when needed via activation (socket, path, timer, D-Bus, udev, scripted systemctl call, ...).
该服务似乎不活跃：
#systemctl status network.service network.service - LSB: Bring up/down networking Loaded: loaded (/etc/rc.d/init.d/network) Active: failed (Result: exit-code) since Thu 2015-09-10 11:46:50 ICT; 28min ago
操作系统：CentOS Linux版本7.1.1503（核心）（最小安装）
不知何故，使用#chkconfig network on工作。
