个人总结:其中有navicat无法链接数据库的异常处理,完全可行
1.从官网下载后解压安装包,复制my-default.int到bin目录下重命名my.ini
my.ini文件如下
# 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 =D:\mysql\mysql-8.0.26-winx64
datadir =D:\mysql\mysql-8.0.26-winx64\data
port =3306
# server_id = .....
character-set-server=utf8
default-storage-engine=INNODB
default-character-set=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
2.修改basedir =D:\mysql\mysql-8.0.15-winx64
datadir =D:\mysql\mysql-8.0.15-winx64\data
自己安装目录地址输入
3.环境变量设置,path下输入bin目录
4.运行CMD敲入命令
安装数据库
mysqld install
初始化数据库文件
mysqld --initialize-insecure --user=mysql --console
5.启动服务 net start mysql
打开计算机管理启动mysql
6.初始化数据库敲入命令 mysql -u root -p
7.修改密码 ALTER USER 'root'@'localhost' IDENTIFIED BY '!Password1';
8.如果navicat无法连接数据库需要更改加密方式
cmd敲入 ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;
更改密码 ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
net stop mysql关闭服务
exit 退出
