MySQL 8.0.11 MacOS 10.13 installation and configuration method graphic tutorial

The process of installing MySQL database and configuring environment variables on Mac is recorded for your reference. The specific contents are as follows

Install mysql. Download mysql. I downloaded: mysql-8.0.11-macos10.13-x86_64.dmg

Double-click to open mysql-8.0.11-macos10.13-x86_64.dmg, and then double-click mysql-8.0.11-macos10.13-x86_64.pkg

Just click on Continue, it's a fool-proof installation, nothing to say

Select "Use Legacy Password Encryption" here, otherwise when you use Navicat to connect to MySQL, you will get an error that the authentication cannot be loaded.

Set a password for the "root" user

Installation Complete

After successful installation, using the mysql command returns the error: command not found, because the environment variables have not been configured.

Configuring environment variables

First, you need to know what kind of Shell you are using on Mac OS X.

Open the terminal and enter: echo $SHELL Press Enter to execute

If the output is: csh or tcsh, then you are using C Shell.

If the output reads: bash, sh, zsh, then you are probably using a variant of the Bourne Shell.

The default shell for Mac OS X prior to 10.2 was C Shell.

The default shell for Mac OS X 10.3 and later is Bourne Shell.

Mine is bash:

Input: cd /usr/local/mysql, press Enter to execute

Then enter: sudo vim .bash_profile, press Enter to execute

You need to enter the root user password. Sudo is used by the root user to modify the environment variable file.

After entering the editor, we first press "i" to switch to the "insert" state. You can edit the content by moving the cursor up, down, left, or right, or by pressing space, backspace, and enter, just like in WINDOWS.

At the bottom of the document, enter: export PATH=${PATH}:/usr/local/mysql/bin

Then press Esc to exit the insert state, and enter :wq at the bottom to save and exit (or directly press shift+zz, or switch to uppercase mode and press ZZ to save and exit).

Input: source .bash_profile and press Enter to execute and run the environment variables.

Then enter the mysql command to use it.

If you cannot connect to MySQL using Navicat,

It probably means that the authentication plugin "caching_sha2_password" cannot be loaded

solve

• Open System Preferences, find MySQL, and click Initialize Database.
• Enter your new password.
• Select 'Use legacy password'.
• Restart the mysql service.
• Navicat links can now be used

After testing, I found that the above method requires re-source .bash_profile every time the terminal is closed and reopened.

PS: The following test is still invalid and has not been resolved yet

Some articles say vi ~/.zshrc, add it here:

export PATH=${PATH}:/usr/local/mysql/bin

After saving, source ~/.zshrc and you can do it once and for all.

Some articles mention modifying ~/.bashrc. If the system is zsh, modifying bashrc is invalid.
