I want to script a rather simple create database operation. Thing
is, I have to provide the password for that database. I would like
to do this with an environment variable, but the simple approach
dose not work:
mailpswd=charlie
mysql -u root -p
CREATE DATABASE mailfix;
CREATE USER 'mailfix'@'localhost' IDENTIFIED BY $mailpswd;
GRANT ALL PRIVILEGES ON `mailfix` . * TO 'mailfix'@'localhost';
Of course the mysql command needs the mysql root password, but that
is as expected. But mysql will not process $mailpswd, not
surprisingly.
I know I could create a file with these commands, sed the password
into the file, then pipe thr file into mysql. I would rather do
this directly without a temp file.
Using the "-e --execute" option you can execute mysql/mariadb
commands from the command line, one at a time. You don't have to put
them into a file first. That should allow you to do what you're
after, including doing variable substitution of the password on the
line you want to execute. You can also put the mysql root pw on that
line with substitution so no prompting is involved.
I saw this, and at first did not like it, as how to manage the mysql
root password, so I found how to use here doc:
mysql -u root -p <<EOF || exit 1
CREATE DATABASE postfix;
CREATE USER postfix@localhost IDENTIFIED BY "$Postfix_Database_Password";
GRANT ALL PRIVILEGES ON postfix.* TO postfix@localhost;
EOF
next refinement is:
mysql -u root -p$mysql_root_Password <<EOF || exit 1
CREATE DATABASE postfix;
CREATE USER postfix@localhost IDENTIFIED BY "$Postfix_Database_Password";
GRANT ALL PRIVILEGES ON postfix.* TO postfix@localhost;
EOF
