MySql5.7 free installation configuration process (ubuntu16.04)

First, the installation environment:

  Operating System: ubuntu16.04

  Database: mysql-5.7.17-linux-glibc2.5-x86_64 (free installation)

Second, unzip

  tar -xzvf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz

  mv mysql-5.7.17-linux-glibc2.5-x86_64   /usr/local/mysql

Third, add users and groups

Sixth, to initialize the database and configuration

  Note: version 5.7.6 is no longer initialize the database after using 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 my.cnf configuration, the initial password 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/mysql

  Configuration environment variable

  mysql_home=/usr/local/mysql
  PATH=$PATH:$mysql_home/bin

Seven, the configuration database and remote access password:

  Use initialization password to log in:

  The password is stored in a log file: sudo vi mysql-error.log

  mysql -u root -p *******

 Initial use, set the root password:
   SET PASSWORD=PASSWORD('root');

  Before you can use and modify the operation of the database:

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

  Modify Remote Access
