mysqldump access denied

问题:

When I try to backup using mysqldump from ssh, I run the following command on machine 10.64.1.1. It gives the following error.

mysqldump --user=test -p=password --host=10.64.1.2 --tab=. databasename tablename

mysqldump: Got error: 1045: Access denied for user 'test'@'10.64.1.1' (using password: YES) when trying to connect

However, I can access mysql using the same user and password.

mysql --user=test -p[password]

Current user: test@10.64.1.1

SSL: Not in use

Current pager: stdout

Using outfile: ''

Using delimiter: ;

Server version: 5.0.91-50-log Percona SQL Server, Revision 73 (GPL)

Protocol version: 10

Connection: 10.64.1.2 via TCP/IP

Updates:

If I do following mysql document: --password[=password] or -p[password].

Since my password contains special symbol @, Mysql cannot detect user correctly. It complains:

mysqldump: Got error: 1044: Access denied for user 'test'@'%' to database

回答1:

I think that you would have to lose the = when using -p or do it with --password :

--password[=password], -p[password]

The password to use when connecting to the server. If you use the short option form (-p), you cannot have a space between the option and the password. If you omit the password value following the --password or -p option on the command line, you are prompted for one. Specifying a password on the command line should be considered insecure. See Section 6.6, "Keeping Your Password Secure".

You have to run CMD.EXE as the Administrator:

Right click on cmd.exe --> Run as Administrator and then type your command:

mysqldump -u[username] -p[password] -h[ip or name] yourdatabasename > c:\sqlfile.sql

It should work fine.

I know the topic is very old, but I happened to have the same issue. I figured out that the problem was just the special character used in the password. In fact they must be escaped with the anti slash: --password=123\@456 or using signle quotes --password='123@456'

回答4:

I had the same problem with a DB user created via Plesk. The user has permissions for a single database. If I specify the database name I get the error mentioned above. If I specify -A for all databases, the dump works.

回答5:

In windows, I resolved it by making a directory and then dumping *.sql file in backup directory.

C:\backup

There are no issues with commands :
Remove the [ ] square brackets

mysqldump -u[username] -p[password] -h[ip] yourdb > C:\backup\sqlfile.sql

It worked for me:)

回答6:

One more possible cause can be the place you are trying to create dump. Writing mysqldump -u[username] -p yourdb > D:\backup\sqlfile.sql instead of mysqldump -u[username] -p yourdb > sqlfile.sql resolved my problem.

回答7:

There is no = (equal sign) for the connection options. You want the following.

mysqldump -u test -ppassword -h 10.64.1.2 ... 

Check out the docs for more details on the other options.

Heres what worked for me- run cmd line as admin. dont put any password after -p, you are automatically prompted to enter a password and it works.
