Linux服务分类方式

一 Linux服务的分类

 

 

二 独立服务

 

 

三 基于xinetd服务

 

基于xinetd服务快讨论

 

四 安装xinetd服务

[root@localhost ~]# yum -y install xinetd

 

五 查看自启动状态

 

 

六实战

1、安装xinetd前查看自启动状态

[root@localhost ~]# chkconfig --list

 

Note: This output shows SysV services only and does not include native

systemd services. SysV configuration data might be overridden by native

systemd configuration.

 

If you want to list systemd services use 'systemctl list-unit-files'.

To see services enabled on particular target use

'systemctl list-dependencies [target]'.

 

netconsole 0:off 1:off 2:off 3:off 4:off 5:off 6:off

network 0:off 1:off 2:on 3:on 4:on 5:on 6:off

2、安装xinetd后查看自启动状态

[root@localhost ~]# chkconfig --list

 

Note: This output shows SysV services only and does not include native

systemd services. SysV configuration data might be overridden by native

systemd configuration.

 

If you want to list systemd services use 'systemctl list-unit-files'.

To see services enabled on particular target use

'systemctl list-dependencies [target]'.

 

netconsole 0:off 1:off 2:off 3:off 4:off 5:off 6:off

network 0:off 1:off 2:on 3:on 4:on 5:on 6:off

 

xinetd based services:

echo-dgram: off
