Mac-can ' t connect to local MySQL server through socket '/tmp/mysql.sock ' (2)

In the terminal input MySQL, the result appears

macdemacbook-pro:~ mac$ alias mysql=/usr/local/mysql/bin/mysqlmacdemacbook-pro:~2002 ( HY000): Can'/tmp/mysql.sock'  (2)

Search the Internet for many ways, not good, and then query the official documents

Http://dev.mysql.com/doc/refman/5.7/en/can-not-connect-to-server.html

The following writes

Here is some reasons the Can‘t connect to local MySQL server error might occur:

• mysqld is isn't running on the local host. Check your operating system ' s process list to ensure, the mysqld process is present.

• 。。。

I didn't think the first one would fit, and then I tried typing mysqld.

Results:

Waiting for a whole bunch of bugs and stuff, and finally quitting.

Finally, the right approach:

macdemacbook-pro:~mac$ sudo mysqld_safepassword:logging to'/usr/local/var/mysql/macdemacbook-pro.local.err'.2018- to-10t07: -: A.6NZ Mysqld_safe starting mysqld daemon with databases from/usr/local/var/MySQL2018- to-10t07: -: A.6NZ Mysqld_safe Mysqld fromPID file/usr/local/var/mysql/macdemacbook-Pro.local.pid Endedmacdemacbook-pro:~mac$ Mysqlerror1045(28000): Access denied forUser'mac'@'localhost'(usingPassword:no)

Then the MYSQLD service is running.

At this point, you can finally open MySQL
