+# MySQL Community Edition (CE) Cheat-Sheet
+
+MySQL Community Edition is the freely downloadable version of the world's most popular open source database.
+
+Project Homepage: [MySQL Community Edition](https://www.mysql.com/products/community/)
+Documentation: [MySQL Docs](https://dev.mysql.com/doc/)
+
+>_Editor's note:_ The MariaDB Project was forked from MySQL when [Sun Microsystems](https://en.wikipedia.org/wiki/Sun_Microsystems)' intellectual property [was acquired](https://en.wikipedia.org/wiki/Acquisition_of_Sun_Microsystems_by_Oracle_Corporation) by [Oracle](https://en.wikipedia.org/wiki/Oracle_Corporation).  MariaDB still shares enormous inter-compatibility with MySQL functions and software interoperability, and performance at most scales is arguably indiscernible from MySQL CE.  In this writers' opinion it is **not beneficial** in most cases to favor Oracle's monetized option over the GPL's MariaDB alternative.

+## Installation
+
+### Install MySQL on Debian/Ubuntu/Mint/Zorin/Deb forks
+
+>[!warning]
+> Common Debian repositories don't populate MySQL CE and require a vendor-provided repository available [here](https://dev.mysql.com/downloads/repo/apt/).  The repo file in this example is current as of 2024-01-20.
+ 
+```bash
+sudo apt update
+sudo apt install -y lsb-release gnupg
+wget https://dev.mysql.com/get/mysql-apt-config_0.8.29-1_all.deb
+sudo dpkg -i mysql-apt-config_0.8.29-1_all.deb
+sudo mkdir /var/lib/mysql
+sudo apt update
+sudo apt install -y mysql-community-server mysql-common mycli --install-recommends
+sudo mysql_secure_installation
+```
+
+### Install MySQL on RHEL/Fedora/CentOS/Alma/Rocky
+
+```bash
+sudo dnf update
+sudo dnf install -y mysql-server mysql-common mycli
+sudo mysql_secure_installation
+```
+
+### Install MySQL on Arch/Manjaro/Arco/ Arch forks
+
+>[!warning]
+> Common Arch repositories don't populate MySQL CE and the vendor doesn't provide one.  The packages are available in the [AUR](https://aur.archlinux.org/) but this is \***not recommended**\* for a production environment!!
+
+##### Enable the AUR (if not already available)
+
+>[!notice]
+>_This **must** be done by a non-root user!_
+```shell
+git clone https://aur.archlinux.org/yay.git
+cd yay
+makepkg -si
+```
+##### Proceed with installation from the AUR
+
+```bash
+yay pacman -Syyu
+yay -S mysql mysql-utilities mycli --noconfirm
+sudo mysql_secure_installation
+```

+## Create Administrative User
+
+Access the MySQL command line by entering `mysql -u root -p` in the shell followed by the Database `root` password.
+
+Create a new user `newuser` for the host `localhost` with a new `password`:
+
+```sql
+CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';
+```
+
+Grant all permissions to the new user
+
+```sql
+GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost';
+```
+
+Update permissions
+
+```sql
+FLUSH PRIVILEGES
+```
