Redis must be restarted after THP is disabled.

Redis Unauthorized Access Vulnerability ————————

Vulnerability Description:

Redis does not require a password to access it by default, and hackers can access all the information in the database, causing serious information leaks.

Fix solution:

1. Bind IP that requires access to the database

Modify the "Bind 127.0.0.1" in redis.conf to the IP address that requires access to this database.

Bind 192.168.31.202 192.168.31.200

Bind 127.0.0.1

2. Set Access password

Find the "requirepass" field in redis.conf and fill in the password you need in the back.

Note: After modifying the above two methods, it is necessary to restart Redis to take effect.
