CentOS7 compilation and installation MySQL 5.6.28 and compilation Parameters

The source code package version after MySQL 5.5 is compiled and installed using the CMake tool. Therefore, you must install the latest version of MySQL in advance. CMake is a cross-platform and open-source software build system that is used to control the software compilation process and generate independent configuration files (makefile or project). You can select the CMake compiler to install the required software during compilation. CMake official website https://cmake.org/, the latest version is 3.4.3.

7. initialize MySQL and related security options.
[Root @ www ~] # Mysql_secure_installation

NOTE: running all parts of this script is recommended for all MySQL
Servers in production use! Please read each step carefully!

In order to log into MySQL to secure it, we'll need the current
Password for the root user. If you 've just installed MySQL, and
You haven't set the root password yet, the password will be blank,
So you shoshould just press enter here.

Enter current password for root (enter for none ):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
Root user without the proper authorisation.

Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables ..
... Success!


By default, a MySQL installation has an anonymous user, allowing anyone
To log into MySQL without having to have a user account created
Them. This is intended only for testing, and to make the installation
Go a bit smoother. You shoshould remove them before moving into
Production environment.

Remove anonymous users? [Y/n] y
... Success!

Normally, root shoshould only be allowed to connect from 'localhost'. This
Ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
... Success!

By default, MySQL comes with a database named 'test' that anyone can
Access. This is also intended only for testing, and shocould be removed
Before moving into a production environment.

Remove test database and access to it? [Y/n] y
-Dropping test database...
... Success!
-Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
Will take effect immediately.

Reload privilege tables now? [Y/n] y
... Success!




All done! If you 've completed all of the above steps, your MySQL
Installation shoshould now be secure.

Thanks for using MySQL!
