Install MySQL under linux as3

The following articles mainly introduce how to install MySQL in the linux operating system. We installed MySQL in the system: linux as3 and MySQL in the environment of mysql-standard-4.0.24-pc-linux-gnu-i686.tar.gz, the following describes how to install MySQL.

System: linux as3

MySQL version: MySQL-standard-4.0.24-pc-linux-gnu-i686.tar.gz

Installation Method: Tarball Installation

MySQL installation path:/usr/local/MySQL

MySQL Installation Process

1. log on to the system as root

2. Copy the downloaded MySQL package to the appropriate location (/usr/lcoal

3. decompress the package

Cd/usr/local # enter the working directory

Tar zxf MySQL-standard-4.0.24-pc-linux-gnu-i686.tar.gz

4. Create a directory connection

Ln-s MySQL-standard-4.0.24-pc-linux-gnu-i686 MySQL

5. Create MySQL users and groups

Groupadd MySQL
Useradd-g MySQL

6. Change the access permission of the MySQL directory.

Chown-R MySQL. # ensure that the current directory is/usr/lcoal/MySQL.
Chgrp-R MySQL.

7. Run the configuration script as a MySQL user

Su-m MySQL # Switch to MySQL user

Cd/usr/local/MySQL # note that after switching the user, the working directory is no longer/usr/local/MySQL. So you have to repeat it.

./Configure # execute the configuration script

8. At this point, the installation has been completed. In some documents, you still need to execute scripts/MySQL_install_db. In fact, this statement is not required because the configure script has already executed this statement. If you execute more statements, an error may occur.

9. Check whether MySQL is successfully installed.

/Usr/local/MySQL/bin/MySQL

If a MySQL prompt is displayed, it indicates that the prompt is successful!

10. automatically enable the MySQL service when the system starts.

Su root # switch back to root user

Cd/usr/local/MySQL

Cp support-files/MySQL. server/etc/init. d/MySQL # copy the msql script file to the startup directory of the system.

Cd/etc/init. d/

Chkconfig -- add MySQL # add MySQL to the startup service list

Chkconfig MySQL on # enable MySQL service automatically when the system starts
