Mysql installation tutorial

Prepare the mysql installation package in advance (download address: http://mirrors.sohu.com/mysql/MySQL-5.6/)

The editor here uses: mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz

If necessary, contact the editor to pass the package to you.

Step 1: create a directory

Mkdir-p / home/lsy/tools

Step 2: transfer the downloaded installation package to the / home/lsy/tools directory.

Cd / home/lsy/tools

Rz mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz

Step 3: extract the mysql binary package

Tar xf mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz

Step 4: add administrative users when the mysql program is running

Useradd-s / sbin/nologin-M mysql

Step 5: move the extracted mysql package to the program directory and rename it

Mkdir-p / application/

Mv / home/lsy/tools/mysql-5.6.34-*-x86_64 / application/mysql-5.6.34

Step 6: create a soft link for the mysql service

Ln-s / application/mysql-5.6.34/ / application/mysql

Step 7: let mysql users manage / application/mysql/

Chown-R mysql.mysql / application/mysql/

Step 8: initialize the database

# 1. Confirm where the software is installed

# 2. Confirm where the data is stored

# 3. Who is the user who confirms the use of MySQL?

/ application/mysql/scripts/mysql_install_db-basedir=/application/mysql-datadir=/application/mysql/data-user=mysql

(the mysql startup script is placed on support-files/mysql.server by default)

Step 9: copy startup script authorization

Cp / application/mysql/support-files/mysql.server / etc/init.d/mysqld

Chmod + x / etc/init.d/mysqld

Step 10: modify the path in the startup script and mysql command

Sed-I's accountUniverse usr _ application/mysql/bin/mysqld_safe _ etc/init.d/mysqld _ MySQL

Step 11: copy the default profile

\ cp / application/mysql/support-files/my-default.cnf / etc/my.cnf

Step 12: start mysql

/ etc/init.d/mysqld start

Step 13: set the mysql password

/ application/mysql/bin/mysqladmin-u root password '123456'

Step 14: simplify the login database command

Echo 'export PATH=/application/mysql/bin:$PATH' > > / etc/profile

Write variables and restart

Source / etc/profile

Check to see if you have changed

[root@mysql] # which mysql

/ application/mysql/bin/mysql

Step 15: set the mysql service to boot automatically

Join the boot self-boot

Chkconfig-add mysqld

Chkconfig mysqld on

Step 16: two ways to enter mysql

[root@mysql] # mysql-u root-p123456

[root@mysql] # mysql-uroot-p

Enter password:123456

Step 17: the way to exit mysql

Enter quit directly on the command line

Or using CTRL + D on the command line is not recommended for CTRL + C
