### --- 服务分类：
### --- RPM包安装的服务：
### --- 独立的服务：
~~~ 启动：
[root@localhost ~]# /etc/rc.d/init.d/httpd star|stop|restart
[root@localhost ~]# service httpd start
~~~ 自启动：
[root@localhost ~]# chkconfig --level 2345 httpd on
[root@localhost ~]# vim /etc/rc.d/rc.local (推荐)
/etc/rc.d/init.d/httpd start
### --- 基于xinetd的服务
~~~ 启动：
[root@localhost ~]# vim /etc/xinetd.d/telnet
disable = yes 改为 disable = no
~~~ 自启动：
[root@localhost ~]# chkconfig telnet on // 不可以写入运行级别号，它是基于xinetd服务的。
[root@localhost ~]# ntsysv
### --- 源码包安装的服务
~~~ 启动：
[root@localhost ~]# /usr/local/apache2/bin/apachectl start|stop|restart|…
~~~ 自启动：
[root@localhost ~]# vim /etc/rc.d/rc.local
/usr/local/apache2/bin/apachectl start
