最近开发环境升级到了 php 5.3.2, 链接 remote mysql 却发生了错误:
(原文链接 http://ddbiz.com/?p=181)
connection failed:SQLSTATE[HY000] [2000] mysqlnd cannot connect to MySQL 4.1+ using old authentication
remote 的 mysql db my.cnf:
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1
是采用兼容格式的密码,而 php5.3的php_mysql; php_pdo_mysql 采用的是增强的密码,所以导致两者不匹配,最方便的方式还是更新db的设置,取消 old_passwords
然后在 mysql.mysql.user,更新所有用户的密码, 如:
update user set password=PASSWORD('new password') where user='this user';
flush privileges;
即可
(原文链接 http://ddbiz.com/?p=181) 不过更新my.cnf 需要重新启动 mysql ,对于应用中的服务器,不是必要就千万别更新php客户端了,哈哈
