Problem with mysqldump: “--defaults-extra-file” option is not working as expected

问题:

I run the following command from the Windows command line to backup my database:

...\right_path\mysqldump --add-drop-database --databases my_database_name                          --defaults-extra-file=d:\1.cnf 

where d:\1.cnf contains the following:

[client] user="my_user" password="my_password" 

Unfortunately, I got the following error message:

mysqldump: unknown variable 'defaults-extra-file=d:\1.cnf' 

If I do:

...\right_path\mysqldump --add-drop-database --databases my_database_name                          --user="my_user" --password="my_password" 

it works as expected.

What am I doing wrong ?

回答1:

I found the answer: --defaults-extra-file must be the first option. This works as expected:

...\right_path\mysqldump --defaults-extra-file=d:\1.cnf                          --add-drop-database --databases my_database_name

I realize this is Linux-specific, but my searches brought me here.

I'm using bitnami's LAMP stack, and found out that their "mysqldump" is actually a script:

LD_LIBRARY_PATH=/opt/lampstack-5.5.3-0/mysql/lib:$LD_LIBRARY_PATH export LD_LIBRARY_PATH case "$@" in   *--no-defaults*)     exec $0.bin "$@"     exit esac exec $0.bin --defaults-file=/opt/lampstack-5.5.3-0/mysql/my.cnf "$@" 

which doesn't appear to allow --defaults-file to be passed in... and work (as per the accepted answer here).
