win10 上面如何安裝多個 MySQL8
1.官網下載 MySQL Community Downloads
https://dev.mysql.com/downloads/mysql/
2.解壓到你要安裝的目錄
3.在MySQL的根目錄下面新建my.ini的配置文件
[mysqld]
# 設置3306端口
port=3306
# 設置mysql的安裝目錄(需要設置為自己的安裝目錄)
basedir=D:\Programming\MySQL8\MySQL1\mysql-8.0.18-winx64
# 設置mysql數據庫的數據的存放目錄(mysql-8.0.18不需要手動創建data文件夾)
datadir=D:\Programming\MySQL8\MySQL1\mysql-8.0.18-winx64\data
# 允許最大連接數
max_connections=200
# 允許連接失敗的次數(這是為了防止有人從該主機試圖攻擊數據庫系統)
max_connect_errors=10
# 服務端使用的字符集默認為utf8mb4
character-set-server=utf8mb4
# 創建新表時將使用的默認存儲引擎
default-storage-engine=INNODB
# 默認使用mysql_native_password插件認證
default_authentication_plugin=mysql_native_password
# 去掉sql_mode中的only_full_group_by
sql_mode=strict_trans_tables,no_zero_in_date,no_zero_date,error_for_division_by_zero,no_engine_substitution
[mysql]
# 設置mysql客戶端默認字符集
default-character-set=utf8mb4
[client]
# 設置mysql客戶端連接服務端時默認使用的端口
port=3306
default-character-set=utf8mb4
4.通過管理員的身份打開cmd窗口跳轉路徑到MySQL的bin目錄
# 進入到mysql的bin目錄底下操作:
# 初始化mysql
mysqld --defaults-file=D:\Programming\MySQL8\MySQL1\mysql-8.0.18-winx64\my.ini --initialize --console
# 安裝mysql服務
mysqld --install [服務名] MySQL1 --defaults-file=D:\Programming\MySQL8\MySQL1\mysql-8.0.18-winx64\my.ini
mysqld --install MySQL1 --defaults-file=D:\Programming\MySQL8\MySQL1\mysql-8.0.18-winx64\my.ini
# 啟動mysql服務
net start [服務名]
net start mysql1
# 停止mysql服務
net stop [服務名]
net stop mysql1
# 卸載mysql服務
mysqld -remove [服務名]
mysqld --remove mysql1
# 登錄mysql
mysql -h localhost -u root -P 3306 -p
# 修改mysql密碼
alter user 'root'@'localhost' identified with mysql_native_password by '123456';
flush privileges;
# 開啟mysql遠程訪問
# 方式一：
use mysql;
create user 'root'@'%' identified by '123456';
grant all on *.* to 'root'@'%';
alter user 'root'@'%' identified with mysql_native_password by '123456';
flush privileges;
# 方式二:
use mysql;
select user,authentication_string,host from user;
update user set host = '%' where user = 'root';
flush privileges;
alter user 'root'@'%' identified with mysql_native_password by '123456';
