一 RPM包安装服务的位置
1、RPM安装服务和源码包安装服务的区别就是安装位置的不同
源码包安装在指定位置，一般是/usr/local
RPM包安装在默认位置中，不需要人为手动指定安装目录，是写这个RPM包的作者规定的位置。
所谓的默认位置，一般为下面这些目录
注意：usr是Unix System Resource，即Unix系统资源的缩写。
二 独立服务的启动
1、Linux通用启动方式
/etc/init.d/独立服务名 start|stop|status|restart
2、redhat系列启动方式
service 独立服务名 start|stop|restart|status
三 实战
[root@localhost ~]# service httpd status
Redirecting to /bin/systemctl status httpd.service
● httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; disabled; vendor preset: disabled)

man:apachectl(8)

四 独立服务自启动
1、第一种方法
chkconfig [--level 运行级别] [独立服务名] [on|off]
2、第二种方法
修改/etc/rc.d/rc.local文件
3、使用npsysv命令管理自启动
