当Linux系统出现重启网卡出现ifup和ifdown文件或目录不存在问题，Shutting down interface eth0: /etc/init.d/functions:line 517:

用service network restart重启网卡报错：

Shutting down interface eth0: /etc/init.d/functions:line 517:./ifdown:No such file or directory [FAILED]

Shutting down loopback interface: /etc/init.d/functions:line 517:./ifdown:No such file or directory [FAILED]

Shutting up loopback interface: /etc/init.d/functions:line 517:./ifup:No such file or directory [FAILED]

Shutting up interface eth0: /etc/init.d/functions:line 517:./ifup:No such file or directory [FAILED]

解决方法：

首先看一下/etc/sysconfig/network-script/目录下是否有这个软连接,我的ifdown和ifup变成了红色的，目录下有这个软链接。

[root@ora10g network-scripts]# ls -lrt ifdown ifup
lrwxrwxrwx 1 root root 12 Dec 9 06:17 ifdown ->../.. /sbin/ifdown
lrwxrwxrwx 1 root root 10 Dec 9 06:17 ifup ->../.. /sbin/ifup

重新创建一下软链接，问题就解决了，命令如下：

[root@ora10g network-scripts]# rm -rf ifdown

[root@ora10g network-scripts]# ln -s /sbin/ifup /etc/sysconfig/network-scripts/ifup
