Detailed steps for installing MySql in Linux: linuxmysql

The following is a record in my work. We will introduce the installation process and screenshot of installing MySql using officially compiled binary files in linux. This installation method is fast and the installation steps are simple!

If you want to install MySql quickly, follow these steps :)!

1. Download the binary installation package for mysql linux:

Address: http://dev.mysql.com/downloads/mysql/

Here I rename the installation package to: tingyun-mysql-5.6.22.tar.gz

Note: You can choose not to rename the file as needed.

2. Unzip the installation package:

Decompress the installation package at the desired location: run the following command:

3. Create the mysql installation directory and modify the directory permissions:

Run the following command:

Create a mysql Directory: mkdir mysql

Open the mysql Directory: cd mysql

Create data directory: mkdir data

Note: Because the mysql service process mysqld will access the data directory during running, you need to create the data directory.

Run the following command in the mysql directory to set the directory owner to a mysql user:

<span style="font-size: 16px; font-family: "Microsoft YaHei"">chown mysql:mysql /opt/mysql –R</span>
