如何在Mac OS上安装“mysql”命令？

Question

I was given a code repo which requires mysql in command line.

I am using Mac OS 10.11

First, I installed MySQL Community Server from http://dev.mysql.com/downloads/mysql/ and install it by running the PKG file.

After that, I opened System Preferences to start MySQL Server.

Then, I tried to execute

/usr/local/mysql/bin/mysql -uroot

and there is an error:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

How could I have mysql in command line?

Thanks,

Typically the command is:

/usr/local/mysql/bin/mysql -u root -p

which will prompt you for your root password (which might be blank unless you changed it)

You can also use:

/usr/local/mysql/bin/mysql -u root -p[password] 

but keep in mind that password will be visible onscreen as you are typing it unlike the straight -p option that will hide your password as you type it when prompted.

Take a look at the options for mysql: https://dev.mysql.com/doc/refman/5.6/en/mysql-command-options.html

In your case, I'd try /usr/local/mysql/bin/mysql -u root -p then hit enter . mysql will prompt you for your password - type in in and hit enter again. If it's wrong mysql will let you know and then you'll have to go about resetting the mysql root password.

https://coolestguidesontheplanet.com/how-to-change-the-mysql-root-password/ is a reasonable set of instructions for doing that in OS X (may be out of date for your version of MySQL but the comments will help) but YMMV depending on where mysql was installed, etc...

Basically those instructions are:

1. sudo /usr/local/mysql/support-files/mysql.server stop
2. sudo mysqld_safe --skip-grant-tables
3. mysql -u root
4. ALTER USER 'root'@'localhost' IDENTIFIED by 'password';
5. FLUSH PRIVILEGES;
6. exit
7. sudo /usr/local/mysql/support-files/mysql.server start

Which

1. Stops mysql
2. Sets mysql to run without bothering with privileges
3. Opens a mysql prompt
4. Updates the root password to 'password' - you should use something else here.
5. "Cleans" passwords (some might say this is unnecessary)
6. Exits the mysql prompt
7. Starts mysql

That should allow you to run mysql -u root -p and use the new password set in #4.
