Ntsysv是redhat 提供的集中管理系统各种服务的工具,在RedHat各个发行版,centos各个版本,都自带这个工具.比起solaris 10的SMF来,要方便很多了, ntsysv一次就可以选中或取消多个服务,而svcadmin只能一个一个的来.
RedHat有2种方法启用ntsysv:一种是直接在命令行下执行命令 ntsysv,另外一种是执行setup命令间接进入.不管是哪种方式进入,其结果都是相同的.下面用图示来说明一下这个过程.
回车后出现下列菜单：
光标定位System services ,再按“Tab”键选“Run Tool”,也可以直接回车.
用空白键（最长的那个）选中或取消服务.选中时,服务的前面的方括号里是“*”,反之则表示取消.设置完毕后,按“Tab”到“ok”回车结束配置.如果直接执行命令ntsysv,步骤就比setup少.
当我们使用ntsysv管理服务时,究竟后面进行的实质是什么？进入当前运行目录/etc/rc3.d(我的系统当前运行级别是3,运行命令 who –r查看之),用命令 ll 列出所有的目录,然后统计一下目录/文件数目：
