Redis does not require password authentication by default. That is to say, you can connect to the redis server as long as the host and port of the connected redis server are correct. This may cause security issues. Therefore, you need to enable the redis authentication password to increase the security of the redis server.

1. modify the configuration file

The configuration file of redis is/etc/redis.conf, Find the following line:

#requirepass foobared

Remove the preceding comment and change it to the required password:

Requirepass mypassword (in which mypassword is the password to be set)

2. Restart redis

If redis has been configuredserviceYou can restart the service in the following ways:

service redis restart

If redis is not configuredserviceYou can restart the service in the following ways:

/usr/local/bin/redis-cli shutdown/usr/local/bin/redis-server /etc/redis.conf

3. logon Verification

After setting the redis authentication password, you must use-aEnter the authentication password. If you do not add this parameter, you can log on successfully, but you do not have any operation permissions. As follows:

$ ./redis-cli -h 127.0.0.1 -p 6379127.0.0.1:6379> keys *(error) NOAUTH Authentication required.

Use the password to authenticate the logon and verify the operation permissions:

$ ./redis-cli -h 127.0.0.1 -p 6379 -a myPassword127.0.0.1:6379> config get requirepass1) "requirepass"2) "myPassword"

The above output shows that reids password authentication is successfully configured.

In addition to the above method-aEnter the logon password. You can also verify the connection without specifying it:

$ ./redis-cli -h 127.0.0.1 -p 6379127.0.0.1:6379> auth myPasswordOK127.0.0.1:6379> config get requirepass1) "requirepass"2) "myPassword"127.0.0.1:6379> 

4. Configure the password on the command line client (valid before redis restarts)

As described aboveredis.confConfigure the password. In this way, you need to restart redis. You can also configure the password through the command line client. In this way, you do not need to restart redis. The configuration method is as follows:

127.0.0.1:6379> config set requirepass newPasswordOK127.0.0.1:6379> config get requirepass1) "requirepass"2) "newPassword"

Note::Use the command line client to configure the password. After redis is restarted, it will still be used.redis.confThe password in the configuration file.

 

5. Use the authentication password in the redis Cluster

If the redis server is used, the cluster is used. BesidesmasterIn addition to configuring the password, you also needslave. InslaveFind the following lines in the configuration file, remove the comments, and modifymasterWith the same password:

# masterauth master-password
