网络编程[32]

1 -- Linux运行级

运行级就是操作系统当前正在运行的功能级别，根据运行级的不同加载不同的系统服务。

2 -- chkconfig命令

usage:

        chkconfig -t|--terse [names]            (shows the links)

        chkconfig -e|--edit  [names]            (configure services)

        chkconfig -s|--set   [name state]...    (configure services)

        chkconfig -l|--list [--deps] [names]    (shows the links)

        chkconfig -c|--check name [state]       (check state)

        chkconfig -a|--add   [names]            (runs insserv)

        chkconfig -d|--del   [names]            (runs insserv -r)

        chkconfig -h|--help                     (print usage)

        chkconfig -f|--force ...                (call insserv with -f)



        chkconfig [name]           same as chkconfig -t

        chkconfig name state...    same as chkconfig -s name state
