Создать базу данных mysql и пользователя в скрипте bash

Кажется, это должно быть просто, и я клянусь, этот код работал месяцами, но сейчас он не работает. Я уверен, что я просто чрезмерно устал, но я был бы признателен, если бы знал, что подталкивание.

# create random password
PASSWDDB="$(openssl Rand -base64 12)"

# replace "-" with "_" for database username
MAINDB=${USER_NAME//[^a-zA-Z0-9]/_}

# create database and user
mysql -e "CREATE DATABASE $MAINDB"
mysql -e "GRANT ALL PRIVILEGES ON $MAINDB.* TO [email protected] IDENTIFIED BY '$PASSWDDB!'"

MAINDB поставляется ранее в сценарии. В итоге я получаю базу данных, пользователя и соответствующие разрешения, а у пользователя есть пароль - это просто не тот пароль, который определен в $ PASSWORDDB.

Это то, что я использую: https://raw.githubusercontent.com/saadismail/useful-bash-scripts/master/db.sh

В вашем случае вы можете использовать это:

# create random password
PASSWDDB="$(openssl Rand -base64 12)"

# replace "-" with "_" for database username
MAINDB=${USER_NAME//[^a-zA-Z0-9]/_}

# If /root/.my.cnf exists then it won't ask for root password
if [ -f /root/.my.cnf ]; then

    mysql -e "CREATE DATABASE ${MAINDB} /*\!40100 DEFAULT CHARACTER SET utf8 */;"
    mysql -e "CREATE USER ${MAINDB}@localhost IDENTIFIED BY '${PASSWDDB}';"
    mysql -e "GRANT ALL PRIVILEGES ON ${MAINDB}.* TO '${MAINDB}'@'localhost';"
    mysql -e "FLUSH PRIVILEGES;"

# If /root/.my.cnf doesn't exist then it'll ask for root password   
else
    echo "Please enter root user MySQL password!"
    read rootpasswd
    mysql -uroot -p${rootpasswd} -e "CREATE DATABASE ${MAINDB} /*\!40100 DEFAULT CHARACTER SET utf8 */;"
    mysql -uroot -p${rootpasswd} -e "CREATE USER ${MAINDB}@localhost IDENTIFIED BY '${PASSWDDB}';"
    mysql -uroot -p${rootpasswd} -e "GRANT ALL PRIVILEGES ON ${MAINDB}.* TO '${MAINDB}'@'localhost';"
    mysql -uroot -p${rootpasswd} -e "FLUSH PRIVILEGES;"

mysql -uroot -p$*PASSWORD_OF_MYSQL_ROOT_USER* -e "CREATE DATABASE $MAINDB"
mysql -uroot -p$*PASSWORD_OF_MYSQL_ROOT_USER* -e "GRANT ALL PRIVILEGES ON $MAINDB.* TO [email protected] IDENTIFIED BY '$PASSWDDB!'"

Это будет работать для вас.

Вы можете использовать heredoc для улучшения восприимчивости вашего SQL:

# create random password
PASSWDDB="$(openssl Rand -base64 12)"

# replace "-" with "_" for database username
MAINDB=${USER_NAME//[^a-zA-Z0-9]/_}

mysql -u root -p<<MYSQL_SCRIPT
CREATE DATABASE $MAINDB;

CREATE DATABASE ${MAINDB} /*\!40100 DEFAULT CHARACTER SET utf8 */;
CREATE USER ${MAINDB}@localhost IDENTIFIED BY '${PASSWDDB}';
GRANT ALL PRIVILEGES ON ${MAINDB}.* TO '${MAINDB}'@'localhost';
FLUSH PRIVILEGES;
