How to solve the problem that the linux modified hosts file does not take effect?

1. Linux often does not take effect after modifying the hostName of native alias / etc/hosts

Linux often does not take effect after modifying the hostName of the native alias / etc/hosts

For example, our / etc/hosts content is as follows:

# 192.68.1.10 message.xxx.com192.68.1.11 message.xxx.com

But ping message.xxx.com still points to 192.68.1.10.

There are two general solutions:

1)。 Restart, which is the most direct, reliable and stable method, if sometimes it is not convenient to restart, you can use the second method.

2)。 Modify the / etc/sysconfig/network file to change the HOSTNAME to the corresponding alias, as follows:

NETWORKING=yesHOSTNAME=host1

Restart the network service after modification

Service network restart (essentially / etc/init.d/network)

3)。 If it still doesn't work after restarting the server, it should be caused by the native dns cache.

Check whether nscd is enabled: ps-ef | grep nscd

Directly shut down the Linux nscd caching service:

/ etc/init.d/nscd stop
