1.什么是系统服务
服务:service提供某些功能,如电源管理上网服务定时任务等。
实现service的程序成为daemon。
一般情况下daemon就等于service。
daemon的主要分类:
stand_alone 自行启动的服务 响应速度快
super_daemon 通过统一的xinetd管理。
查看服务于端口号的对应关系:cat /etc/service
daemon的启动方式与启动脚本
启动方式:直接使用脚本
/etc/init.d/*启动脚本放置处
/etc/sysconfig/* 配置文件
/etc/xinetd.config, /etc/xinetd.d/* super daemon 配置文件
查看启动状态如: /etc/init.d/syslog satus
启动如:/etc/init.d/syslog restart
防火墙管理:文件加入ip etc/hosts.allow etc/hosts.deny
