Where is the mysql authentication method?

MySQL authentication methods mainly include: Password-based authentication: The user provides a username and password, and the password is stored in hash form. Certificate-based authentication: Use SSL certificates to authenticate users, with each user having a unique public and private key. Kerberos-based authentication: Using the Kerberos protocol, users only need to authenticate once to the Kerberos server to access multiple services. LDAP-based authentication: Uses an LDAP directory server to authenticate users.

MySQL authentication methods

MySQL provides a variety of authentication methods to ensure the security of database access . There are mainly the following types:

Password-based authentication

• The most common authentication method.
• Users need to provide a username and password to the MySQL server.
• Passwords are stored in the database in hashed form and cannot be cracked.

Certificate-based authentication

• Use an SSL certificate to authenticate users.
• Each user has a unique public key and private key pair.
• The MySQL server compares the public key with the request to authenticate the user.

Kerberos-based authentication

• Uses the Kerberos protocol for authentication.
• A trust-based system in which users only need to authenticate once to the Kerberos server to be authorized to access multiple services.

LDAP-based authentication

• Uses Lightweight Directory Access Protocol (LDAP) for authentication.
• Authenticate users by connecting to an LDAP directory server.

Authentication method settings

Modify the MySQL configuration file (my.cnf or my.ini ) to configure the authentication method.

1. Password-based authentication:

   <code>[mysql]
   password=<password></code>

2. Certificate-based authentication:

   <code>[mysql]
   ssl-ca=<path/to/ca-certificate.pem>
   ssl-cert=<path/to/client-certificate.pem>
   ssl-key=<path/to/client-key.pem></code>

3. Kerberos based authentication:

   <code>[mysql]
   plugin_load="auth_kerb=libauth_kerb.so"</code>

4. LDAP based authentication:

   <code>[mysql]
   plugin_load="auth_ldap=libauth_ldap.so"</code>

   Then configure the LDAP server details in the [auth_ldap] section.

Choosing the most appropriate authentication method depends on the needs and security considerations of your specific application. If you need a higher level of security, certificate or Kerberos authentication may be a better choice.
