CentOS 7 安装telnet服务

今天测试zabbix需要用到telnet服务，查询到Centos7下下载安装telnet服务的方法，特此整理记录！

一、通过yum下载安装telnet

yum -y install xinetd telnet telnet-server

vi /etc/securetty

　　将下面两行语句添加到文档末尾处， :wq! 保存退出

pts/0

pts/1

vi /etc/sysconfig/iptables

-A INPUT -p tcp -m state --state NEW -m tcp --dport 23 -j ACCEPT

　　重启防火墙服务，使配置生效

systemctl restart iptables

systemctl disable firewalld

systemctl stop firewalld

systemctl enable telnet.socket

systemctl start telnet.socket

systemctl enable xinetd

systemctl start xinetd
