解决CentOS 7.3网络服务不能重启问题。
1.首先把创建一个临时目录虚拟挂载光驱内容: mkdir /mnt/cdrom 2.挂载光驱内容到临时目录: mount -t auto /dev/cdrom /mnt/cdrom 3.清空CentOS-Base.repo文件: >/etc/yum.repos.d/CentOS-Base.repo 4.重新编译CentOS-Base.repo文件: [base] name=CentOS-$releasever - Base baseurl=file:///mnt/cdrom/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 [updates] name=CentOS-$releasever - Updates baseurl=file:///mnt/cdrom/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 [extras] name=CentOS-$releasever - Extras baseurl=file:///mnt/cdrom gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 :wq! 5.清空yum源历史记录和缓存: yum clean all yum makecache 6.安装NetworkManager-tui: yum install -y NetworkManager-tui //必须区分大小写,否则安装不成功。 7.重启网络服务正常: systemctl restart network
8.使NetworkManager开机启动:
systemctl enable NetworkManager.service //记得这一句敲上,否则下次重启网卡服务起不来。
