linux CentOS 安装telnet

1.在安装Telnet前先检查系统是否安装了telnet-server和xinetd

rpm -qa telnet-server
 
rpm -qa xinetd

2.如果没有安装，则开始安装，安装之前先查找Telnet的安装包

yum list | grep telnet-server
 
yum list | grep xinetd

3.执行安装语句

yum -y install telnet-server.x86_64
yum -y install telnet.x86_64
yum -y install xinetd.x86_64

4.设置开机自启

systemctl enable xinetd.service
systemctl enable telnet.socket

5.开启service（重点）

systemctl start telnet.socket
systemctl start xinetd
