Client does not support authentication protocol requested\r\nby server; consider upgrading MySQL client\r\n\r\nMYSQL\u5b98\u65b9\u7684\u89e3\u6c7a\u65b9\u5f0f\u5982\u4e0b:<\/pre>\nMySQL 5.0 uses an authentication protocol based on a password hashing algorithm that is incompatible with that used by older (pre-4.1) clients. If you upgrade the server from 4.0, attempts to connect to it with an older client may fail with the following message:<\/p>\n
shell>
mysql<\/code><\/strong> Client does not support authentication protocol requested by server; consider upgrading MySQL client<\/p>\nTo solve this problem, you should use one of the following approaches:<\/p>\n
\n\n
- Upgrade all client programs to use a 4.1.1 or newer client library.<\/li>\n
- When connecting to the server with a pre-4.1 client program, use an account that still has a pre-4.1-style password.<\/li>\n
- Reset the password to pre-4.1 style for each user that needs to use a pre-4.1 client program. This can be done using the
SET PASSWORD<\/code> statement and theOLD_PASSWORD()<\/code><\/a> function:\nmysql>SET PASSWORD FOR<\/code><\/strong>\r\n->'some_user<\/code><\/em>'@'some_host<\/code><\/em>' = OLD_PASSWORD('newpwd<\/code><\/em>');<\/code><\/strong><\/pre>\nAlternatively, use
UPDATE<\/code> andFLUSH PRIVILEGES<\/code>:<\/p>\nmysql>UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd<\/code><\/em>')<\/code><\/strong>\r\n->WHERE Host = 'some_host<\/code><\/em>' AND User = 'some_user<\/code><\/em>';<\/code><\/strong>\r\nmysql>FLUSH PRIVILEGES;<\/code><\/strong><\/pre>\nSubstitute the password you want to use for \u201c
newpwd<\/code><\/em><\/span>\u201d in the preceding examples. MySQL cannot tell you what the original password was, so you’ll need to pick a new one.<\/li>\n- Tell the server to use the older password hashing algorithm:\n
\n\n
- Start mysqld<\/strong><\/span> with the
--old-passwords<\/code> option.<\/li>\n- Assign an old-format password to each account that has had its password updated to the longer 4.1 format. You can identify these accounts with the following query:\n
mysql>SELECT Host, User, Password FROM mysql.user<\/code><\/strong>\r\n->WHERE LENGTH(Password) > 16;<\/code><\/strong><\/pre>\nFor each account record displayed by the query, use the
Host<\/code> andUser<\/code> values and assign a password using theOLD_PASSWORD()<\/code><\/a> function and eitherSET PASSWORD<\/code> orUPDATE<\/code>, as described earlier.<\/li>\n<\/ol>\n<\/div>\n<\/li>\n<\/ul>\n<\/div>\n\nNote<\/h3>\n
In older versions of PHP, the
mysql<\/code> extension does not support the authentication protocol in MySQL 4.1.1 and higher. This is true regardless of the PHP version being used. If you wish to use themysql<\/code> extension with MySQL 4.1 or newer, you may need to follow one of the options discussed above for configuring MySQL to work with old clients. Themysqli<\/code> extension (stands for “MySQL, Improved”; added in PHP 5) is compatible with the improved password hashing employed in MySQL 4.1 and higher, and no special configuration of MySQL need be done to use this MySQL client library. For more information about themysqli<\/code> extension, see http:\/\/php.net\/mysqli<\/a>.<\/p>\n<\/div>\nIt may also be possible to compile the older
mysql<\/code> extension against the new MySQL client library. This is beyond the scope of this Manual; consult the PHP documentation for more information. You also be able to obtain assistance with these issues in our MySQL with PHP forum<\/a>.<\/p>\n
