[英]perl DBI connect to mysql database without password
I would like to use DBI to connect to a mysql database as user mysql, but without password. 我想使用DBI以mysql用户身份连接到mysql数据库,但没有密码。 Is this possible?
这可能吗?
Example: 例:
#create database, grant access to mysql
mysql -e 'create database perltest; grant all on perltest.* to mysql@localhost'
my perl code: 我的Perl代码:
#!/usr/bin/perl -w
use DBI;
$dbh = DBI->connect('dbi:mysql:perltest','mysql', NULL)
or die "Connection Error: $DBI::errstr\n";
So the third argument for DBI->connect
is the password. 因此,
DBI->connect
的第三个参数是密码。 In all examples I have seen, a password is used. 在我看到的所有示例中,都使用了密码。 I tried various things as the third argument:
NULL
, null
, ''
, ' '
etc., but every time it is interpreted as a password. 我尝试了各种方法作为第三个参数:
NULL
, null
, ''
, ' '
等,但是每次将其解释为密码时。 Any ideas? 有任何想法吗?
just use undef
: 只需使用
undef
:
$dbh = DBI->connect("DBI:mysql:perltest","mysql",undef,{ RaiseError => 1 });
UPD. UPD。 btw, this fiddle is probably helpful explanation of how perl operates with all this null/0/undefined stuff.
顺便说一句, 这个小提琴可能是有关perl如何使用所有null / 0 / undefined东西的有用说明。 Got original code from here
