one. Install MySQL1.mysqlhttp://dev.mysql.com/downloads/mysql/my machine is Mac 10.8, so use MYSQL-5.6.10-OSX10.7-X86_64.DMG install package; 2. Install package on HDD image (. dmg) file, you must first double-click the icon in the search to install the file. You should install the image and display its contents.

Note: Be sure to close all running MySQL server instances using the MySQL Manager application (on Mac OS x server) or mysqladmin shutdown on the command line before continuing with the installation.
MySQL's Mac OS X pkg is installed to/usr/local/mysql-version, and a symbolic connection is also installed,/usr/local/mysql, pointing to the new location. If you have a/usr/local/mysql directory, rename it to/usr/local/mysql.bak first. When the installation is complete, the installer executes mysql_install_db to create the authorization table in the MySQL database.

The installation layout is similar to the tar file binary distribution; All MySQL binaries are in directory/usr/local/mysql/bin. By default, the MySQL socket file is created as/tmp/mysql.sock.

There are two ways to install MySQL under Mac, one for Compressed Package FormAnother type of . dmg File Installation package

First, we introduce the installation method of the compressed package form:

$ sudo mv mysql-5.1.45-osx10.6-x86_64 /usr/local/mysql
$ cd /usr/local
$ sudo chown -R mysql:mysql mysql
$ cd mysql
$ sudo scripts/mysql_install_db --user=mysql
$ sudo chown -R root .
$ sudo chown -R mysql data

Then CD bin with
$ sudo ./mysql_secure_installation
To modify the root password, which is empty by default, is obviously less secure, and is then configured as appropriate, as the development environment is less restrictive.

$ sudo ./mysqld_safe
To start MySQL

$ sudo ./mysql -u root -p
Enter the root password you just set to log in to MySQL

$ sudo ./mysqld_safe stop
Stop MySQL

Installation package file Form installation method:
