Windows安装mysql8.0.11

准备

Mysql8.0.11下载: 官方下载
环境：Windows 7/Windows 10

安装

1. 解压zip包到安装目录
   比如我的目录为：D:\mysql-8.0.11-winx64
2. 配置文件
   在根目录下新建data文件夹（data文件夹必须为空），并在D:\mysql-8.0.11-winx64添加my.ini文件，写入基本配置

[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 = D:\mysql-8.0.11-winx64
datadir = D:\mysql-8.0.11-winx64\data
port = 3306
# server_id = .....


# 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 

character-set-server = utf8mb4

performance_schema_max_table_instances = 600
table_definition_cache = 400
table_open_cache = 256

[mysql]
default-character-set = utf8mb4

[client]
default-character-set = utf8mb4

注意修改上述配置文件中basedir和datadir目录。

3. 添加环境变量
   将D:\mysql-8.0.11-winx64\bin添加到系统Path中，注意必须为系统Path中，用户Path不可行。

4. 初始化数据库
   mysqld --initialize --console
   执行完成后，会打印初始密码
   

5. 安装服务
   以管理员身份执行命令mysqld --install mysqld
   之后可以通过net start mysqld启动mysql服务，net stop mysqld关闭mysql服务。
   

更改密码

在Mysql命令中执行
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
将密码改为123456.

速度测试

官方说MySQL8比5快两倍。
