在bash脚本中创建mysql数据库和用户 [英] Create mysql database and user in bash script

问题描述

这看起来应该很简单，我发誓这段代码已经使用了几个月了，但是现在不起作用了.我确定我只是太累了，但我会感谢一位知情的朋友.

This seems like it should be simple and I swear this code has worked for months but it's not working now. I'm sure I'm just overly tired but I would appreciate a knowing nudge.

# 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，并且该用户具有一个密码-它不是$ PASSWORDDB中定义的密码.

MAINDB is supplied previously in the script. What I end up with is a database, a user, and proper permissions and the user has a password - it's just not the password defined in $PASSWORDDB.

推荐答案

这是我使用的:您可以使用以下方法:

# 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!"
    echo "Note: password will be hidden when typing"
    read -sp 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
