How to solve the problem that linux can't access the ip address?

The solution is as follows:

1. Edit the / etc/sysconfig/iptables configuration file and add the following configuration:

-An INPUT-m state-- state NEW-m tcp-p tcp-s 127.0.0.1-- dport 6379-j ACCEPT / / An INPUT-m state-- state NEW-m tcp-p tcp-s 126.212.173.185-- dport 6379-j ACCEPT / / an open pair of 126.212.173.185 hosts

If you do not restrict ip to all hosts, you can remove-s [ip].

In newly installed Linux systems, firewalls are disabled by default, and generally no firewall policies are configured, so the / etc/sysconfig/iptables file does not exist.

Solution:

Installation:

Yum install iptables-services

After the installation is successful: you can find the / etc/sysconfig/iptables configuration file and follow the above steps to write the open port.

2. After modification, you need to restart the iptables service with the following command:

Systemctl start iptables

You may also need to restart the service program to access the service port, such as 9093.

Turn on firewall filtering rules:

Systemctl enable iptables / / set to enable startup
