在Windows10上安装配置MySQL5.8

1. 下载MySQL8.0 Windows zip包

下载地址

1. 解压至安装目录

2. 将安装目录/bin添加到PATH环境变量里

3. 在安装目录下新建文件my.ini并写入基本配置

[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是安装目录
basedir = D:ProgramMySQL
# datadir是mysql数据目录
datadir = D:DBsMySQL
# 端口号
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

1. 初始化数据库
   执行mysqld --initialize --console
   执行完成后，会打印 root 用户的初始默认密码，比如：

2018-04-20T02:35:01.507037Z 0 [Warning] [MY-010915] [Server] 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode. They will be merged with strict mode in a future release.
2018-04-20T02:35:01.507640Z 0 [System] [MY-013169] [Server] D:ProgramMySQL8binmysqld.exe (mysqld 8.0.11) initializing of server in progress as process 11064
2018-04-20T02:35:01.508173Z 0 [ERROR] [MY-010340] [Server] Error message file 'D:ProgramMySQLshareenglisherrmsg.sys' had only 1090 error messages, but it should contain at least 4512 error messages. Check that the above file is the right version for this program!
2018-04-20T02:35:05.464644Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: APWCY5ws&hjQ
2018-04-20T02:35:07.017280Z 0 [System] [MY-013170] [Server] D:ProgramMySQL8binmysqld.exe (mysqld 8.0.11) initializing of server has completed

其中，第4行的“APWCY5ws&hjQ”就是初始密码，在没有更改密码前，需要记住这个密码，后续登录需要用到。
6. 安装服务
执行mysqld --install

1. 登录mysql
   mysql -uroot -p
   然后输出之前的初始密码

2. 修改登录密码

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
