-D指定db登陆失败

#mysql -ulzl -p123456  -Dlzldb --socket=/my3456/mysql.sock               
Warning: Using a password on the command line interface can be insecure.
ERROR 1044 (42000): Access denied for user 'lzldb'@'%' to database 'lzldb'

困扰了很久，查了user没有问题。

原因很简单 -D参数要加到后面

#mysql -ulzl -p123456  --socket=/my3456/mysql.sock -Dlzldb

总结我已知的mysq参数问题：

1 mysql命令参数还是很敏感的，还是要注意参数顺序

2 -D参数尽量靠后

3 --defaults-file必须放在第一个参数
