MySQL 5.7 Windows installation strategy

After mysql 5.7 windows is decompressed, it can only be installed manually. That’s just right. The main points are as follows


1. Decompression

2. Rename my_default.ini to my.ini, and then at least open and edit as follows:

[client]

port=3309

[mysql]
default-character- set=utf8
[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
basedir ="C:\mysql5.7"
datadir = "C :\mysql5.7/mysql57data"
port = 3309
# server_id = .....
default-storage-engine=INNODB

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
join_buffer_size = 128M sort_buffer_size = 2M read_rnd_buffer_size
= 2M

sql_mode=NO_ENGINE_SUBSTITUTION, STRICT_TRANS_TABLES


Other parameters can be adjusted by referring to the Internet

3 Set the PATH, which is convenient for command line invocation in DOS

mode. Open the command line and
enter                                                  : mysqld -install
  // Execute the installation operation

mysqld --defaults-file=d:\mysql\my.ini --initialize-insecure --console
--defaults-file The parameter specifies the location of the configuration file to be used
The –initialize-insecure parameter is a newly added initialization database parameter in MySql 5.7.7. This parameter indicates that a root user without a password is created while initializing the database. The
–console parameter indicates that the log is output to the command line interface .

5 Create a service
  mysqld -- install MYSQL57 --defaults-file=d:\mysql\my.ini
can remove
  mysqld --remove MYSQL57
6 Start the service under the control panel

7 The default mysql -u root -p on the command line, do not enter a password, pay attention to change The root password is different! And the previous version, like this:
   use mysql;
//Enter the mysql database.
UPDATE user SET authentication_string=PASSWORD("new password") WHERE User='root';
//Modify the root account password.
FLUSH PRIVILEGES;
//Refresh MySQL's system privilege related tables, otherwise access will be denied.
quit;
//Exit mysql.
