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?
2 Answers
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 :-)

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– geoffleeMay 30, 2015 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. Jan 10, 2018 at 14:39
