I have to log into multiple MYSQL DB's on different hosts via mysql cli. is it possible to save these logins so I don't have to trackdown/remember the credentials?

Based on a discussion at http://bugs.mysql.com/bug.php?id=17627 I use the following method to automatically log into different mysql servers:

File /path/to/my-host1-cnf.txt

[client]
host="hostname1"
user="username1"
password="password1"
database="database1"

File /path/to/my-host2-cnf.txt

[client]
host="hostname2"
user="username2"
password="password2"
database="database2"

Connect to host1, database1 with saved credentials above:

mysql --defaults-file="/path/to/my-host1-cnf.txt"

Connect to host2, database2 with saved credentials above:

mysql --defaults-file="/path/to/my-host2-cnf.txt"

Hope this helps :-)

    This looks like it might be what I need. Thanks! – veilig Apr 27 '11 at 6:10

You can always create an aliases to it

alias db1='mysql -uUsername1 -pPasswordSecure1 -hHosname1 DatabaseName1'
alias db2='mysql -uUsername2 -pPasswordSecure2 -hHosname2 DatabaseName2'

etc..

And put them into your

.bash_aliases

.barsh_profile

or

.bash_rc

But this doesn't solve the security issue! Even if you put "good" permission on your bash files it doesn't mean it isn't plain text :(

  • This is not safe! "This is convenient but insecure. On some systems, your password becomes visible to system status programs such as ps that may be invoked by other users to display command lines." dev.mysql.com/doc/refman/5.1/en/password-security-user.html – geofflee May 30 '15 at 9:53
  • Putting your password in plain text is never a good idea. Even if you secure your files it still executes as a command which will show up in ps aux, your .bash_history, etc. – blockloop Jan 10 '18 at 14:39
