解压版mysql安装步骤

Posted 2022-08-09 topguntopgun

第一步：解压mysql，例如解压后的目录在C:\Program Files\mysql-5.6.36-winx64

第二步：配置mysql环境变量，类似配置java的环境变量

计算机右键===>属性===>高级系统设置===>高级===>环境变量

新建系统变量：

变量名：MYSQL_HOME

       变量值：C:\Program Files\mysql-5.6.36-winx64

编辑系统变量Path，追加%MYSQL_HOME%\bin;

 

第三步：进入C:\Program Files\mysql-5.6.36-winx64，将my-default.ini重命名为my.ini，并进行如下配置(红色字体)：

# For advice on how to change settings please see

# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html

# *** DO NOT EDIT THIS FILE. It‘s a template which will be copied to the

# *** default location during install, and will be replaced if you

# *** upgrade to a newer version of MySQL.

 

[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 = .....

# datadir = .....

# port = .....

# server_id = .....

basedir = C:\Program Files\mysql-5.6.36-winx64

datadir = C:\Program Files\mysql-5.6.36-winx64\data

character_set_server=utf8

 

# 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

[client]

default-character-set=utf8

 

第四步：使用管理员操作DOS命令，依次输入：

              进入mysql的bin目录：cd C:\Program Files\mysql-5.6.36-winx64\bin

              安装mysql：mysqld –install

              启动mysql服务器：net start mysql

              登陆mysql：mysql –uroot –p   回车，这时提示输入密码，暂时没有密码，直接回车即可

 

第五步：修改mysql的root账户的密码，继续输入如下命令：

use mysql;

update user set password=password("新密码") where user="root";

flush privileges;

 

 

第五步有些版本是错误的，

命令如下：

1、use mysql;

2、alter user ‘root‘@‘localhost‘ identified with mysql_native_password by ‘********‘;

3、flush privileges;
