How to set the Centos Redis configuration password

Setting a password for Redis in CentOS system can be achieved by modifying the configuration file or temporarily setting it using the command line.

Method 1: Modify the redis.conf configuration file

1. Positioning Redis configuration files: The Redis configuration files are usually located in /etc/redis/redis.conf .

2. Edit configuration file: Open the configuration file using a text editor (such as vi or nano ):

    sudo vi /etc/redis/redis.conf

3. Set password: Find requirepass line (add if not), and replace the value after it with the password you selected:

    <code>requirepass your_strong_password</code>

   Important: Be sure to use a strong password and keep it safe.

4. Save and exit: Save the configuration file and exit the editor ( vi : :wq , nano : Ctrl O, Ctrl X).

5. Restart Redis service: Make the configuration take effect:

    sudo systemctl restart redis

6. Verify password: Use redis-cli to connect and verify:

    redis-cli -h localhost -p 6379
   AUTH your_strong_password

   If OK is displayed, the password setting is successful.

Method 2: Temporary password setting on the command line (not recommended for production environment)

This method is only used in test or temporary situations and is not recommended for long-term use in production environments, because the password will fail after restarting Redis.

1. Connect to Redis:

    redis-cli -h localhost -p 6379

2. Set password (CONFIG SET requirespass your_password):

    CONFIG SET requirespass your_temporary_password

3. Verify password: Try executing a command, such as SET test_key "test_value" .

Safety Tips:

• Strong password: Use complex and difficult to guess passwords.

• Backup configuration file: Before modifying the configuration file, it is recommended to backup:

   sudo cp /etc/redis/redis.conf /etc/redis/redis.conf.bak

• Access control: In addition to password protection, consider using other security measures such as firewalls to limit access to Redis servers.

Through the above steps, you can safely set the Redis password on the CentOS system. Recommended usage method 1, that is, modify the configuration file to ensure that the password settings are durable and effective.
