chkconfig 使用范例：
chkconfig --list        #列出所有的系统服务
chkconfig --add httpd        #增加httpd服务
chkconfig --del httpd        #删除httpd服务
chkconfig --level httpd 2345 on        #设置httpd在运行级别为2、3、4、5的情况下都是on（开启）的状态
chkconfig --list        #列出系统所有的服务启动情况
chkconfig --list mysqld        #列出mysqld服务设置情况
chkconfig --level 35 mysqld on        #设定mysqld在等级3和5为开机运行服务，--level 35表示操作只在等级3和5执行，on表示启动，off表示关闭
chkconfig mysqld on        #设定mysqld在各等级为on，“各等级”包括2、3、4、5等级

如何增加一个服务：
1.服务脚本必须存放在/etc/ini.d/目录下；
2.chkconfig --add servicename
    在chkconfig工具服务列表中增加此服务，此时服务会被在/etc/rc.d/rcN.d中赋予K/S入口了；
3.chkconfig --level 35 mysqld on
    修改服务的默认启动等级。
