centos6.x误删除/sbin/service怎么恢复？具体解决方法：
首先，执行yum,rpm命令查看相关软件包。
复制代码 代码示例:
# yum list | grep initscripts
initscripts.x86_64 9.03.31-2.el6.centos@anaconda-CentOS-201207061011.x86_64/6.3
initscripts.x86_64 9.03.40-2.el6.centos.1 updates
不知道yum命令用法的朋友，请参考文章：
上面给出了可安装软件的yum源版本。
复制代码 代码示例:
# rpm -qa | grep initscripts
initscripts-9.03.31-2.el6.centos.x86_64
上面是目前系统已安装的initscripts情况，因为误删了service文件，显然已经出现了错误，然后执行
复制代码 代码示例:
# yum install initscripts
Loaded plugins: fastestmirror

* base: mirrors.btte.net

安装完成后，发现service已经存在于/sbin目录下
复制代码 代码示例:
# ll /sbin/service
-rwxr-xr-x 1 root root 1694 Feb 20 18:44 /sbin/service
# rpm -qa | grep initscripts
initscripts-9.03.40-2.el6.centos.1.x86_64
软件做了一个小版本更新。
另外，有详service命令的用法，可以参考：centos网络基本命令全解(service、ifconfig、netstat)
