Response One
What is the purpose of the mysql_install_db script?
msql_install_db is a script used on UNIX-based machines that creates the basic file directory and grant tables for user permissions automatically. Usually this script is run automatically because it is in the installation package.
What are some of the problems that can occur while running the mysql_install_db script?
mysql_install_db could fail for a number of reasons. The most common reasons are “mysql fails to install the grant tables”, “there is a mysqld process already running”, and “you do not have access to the /tmp directory”.
Why are usernames considered just as important as passwords?
When setting up MySQL for the first time on Unix-based machines, the configuration script creates 5 default accounts and they all have no passwords. If a nefarious individual decided to try and get into your database, they could use one of the default accounts since the named default accounts are always root@localhost, root@12.0.0.1, and root@hostname. This is in addition to the two anonymous accounts created by default. Changing the username is important when it comes to initial setup, because of easy password guessing. By also changing the username, administrators have now added an extra layer of security to their database.
Response Two
The script, mysql_install_db, is ran typically after MySQL has been installed on a Unix like machine and it needs to be configured. Running the script will set up the basic file directory and grants table for user permissions automatically (Basta, Zgola 2011). Some systems actually run this script automatically upon installation of MySQL, such as Linux. If it does not run the script automatically, then you must navigate to the installation directory to run it.
Running the mysql_install_db script may not always work. Some common problems could be a mysqld process already running, not having access to the /tmp directory, a server already being ran on the machine, or a failure to install grant tables (Security In MySQL n.d.). Most of the fixes to these are self explanatory except for the failure to install grant tables, for which you should examine the error logs that are generated upon failure of the install.
Usernames are just as important as passwords. I challenge everyone to look at all of their online accounts and reflect on the usernames you’ve chosen. Most cases, a lot of us, me included, use the same username as the rest of our accounts if possible. This can be dangerous for the same reason as passwords. The only difference is the username is public. This is an issue because it lets people with evil intent create an online profile for us. If someone with malicious intent gets into one of our accounts, then they essentially have access to all of our accounts if we share the same usernames and passwords (Scott, 2020). I strongly encourage everyone takes a look at their accounts and consider switching things up and creating unique usernames for each account.
