一、简单检查

### --- 简单检查：

~~~     使用ICMP协议或者TCP协议进行检查某个服务或者设备的存活。
~~~     关闭zabbix-agent.service模拟测试，

二、SMTP检查：

### --- 安装postfix   检查SMTP服务。

[root@localhost ~]# vim /etc/postfix/main.cf                        // 邮件传输代理软件
inet_interfaces = 192.168.1.60
mydestination = $myhostname, localhost.$mydomain, localhost         // localhost开放

[root@localhost ~]# systemctl restart postfix.service 
 
[root@localhost ~]# ss -tunlp
users:(("sshd",pid=22755,fd=3))
tcp    LISTEN     0      100           192.168.1.60:25                                   *:*    

### --- 简单检查我们的25端口开启

[root@localhost ~]# telnet 192.168.1.60 25                          
Trying 192.168.1.60...
Connected to 192.168.1.60.
Escape character is ^].
220 localhost.localdomain ESMTP Postfix
ctrl+]
telnet>quit

1、SMTP的值是1

2、ICMP检查：

### --- 安装fping工具：

[root@localhost ~]# yum -y install fping
[root@localhost ~]# ping 192.168.1.59
PING 192.168.1.59 (192.168.1.59) 56(84) bytes of data.
64 bytes from 192.168.1.59: icmp_seq=1 ttl=64 time=2.53 ms

3、ICMP显示的是ping值
