在bash脚本中创建mysql数据库和用户

Question

这看起来应该很简单，我发誓这段代码已经工作了好几个月，但现在不工作。我确信我只是太累了，但我会很感激一个知道的微调。

# 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 $MAINDB@localhost IDENTIFIED BY '$PASSWDDB!'" 

MAINDB先前在脚本中提供。我最终得到的是一个数据库，一个用户和适当的权限，并且用户有一个密码 - 它不是在$ PASSWORDDB中定义的密码。

Answer 1

这是我使用方法：https://raw.githubusercontent.com/saadismail/useful-bash-scripts/master/db.sh

你的情况，你可以使用这个：

# 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;" 
fi 

Answer 2

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 $MAINDB@localhost IDENTIFIED BY '$PASSWDDB!'" 

这会为你工作。
