Install MySQL-5.7.17 with general binary installation package under Linux

Decompress the copy

Mv mysql-5.7.14-linux-glibc2.5-i686 / usr/local/mysql

Create a mysql user first

Groupadd mysqluseradd-r-g mysql-s / bin/false mysql

Create a data directory for mysql that will be used when initializing the database

Mkdir / mysql/ mysql/data / mysql/log

Modify directory permissions

Chown-R mysql:mysql / usr/local/mysql / mysql

Create a my.cnf file

Vim / etc/my.cnf

= / tmp/== = / tmp/= / usr/local/= / mysql/-file = / mysql/data/= = = = [innodb] = = = [log] = / mysql/log/mysql-= / mysql/log/mysql-

Description: here are just some simple configurations.

Initialize the database

The initialization method before 5.7.6 is: bin/mysql_install_db-- user=mysql

I downloaded the latest version 5.7.12, which was just released on April 12th. The version after 5.7.6 initializes the database and no longer uses mysql_install_db.

Bin/mysqld-initialize-user=mysql-basedir=/usr/local/mysql-datadir=/mysql/data-innodb_undo_tablespaces=3-explicit_defaults_for_timestamp

If log_error for my.cnf is configured, the initial password is in the log_error file, otherwise it will be printed.

Bin/mysql_ssl_rsa_setup-datadir=/mysql/data

Modify directory permissions

Chown-R mysql:mysql / usr/local/mysql / mysql

Configure the startup file

Cp support-files/mysql.server / etc/init.d/mysqlchkconfig-- add mysqlchkconfig mysql onservice mysql start

Configure environment variables

Mysql_home=/usr/local/mysqlPATH=$PATH:$mysql_home/binsource / etc/profile

Modify the password

The field in which the password is stored in 5.7is no longer password, it becomes authentication_string

Update mysql.user set authentication_string=password ('root') where user='root'

After changing the root password, if you log in to the mysql system for the first time using root users, you will need to reset the root password.

SET PASSWORD=PASSWORD ('root'); flush privileges
