MySQL5.7.21安裝與密碼圖文配置教程
MySQL5.7.21安裝與密碼設(shè)置教程,具體如下
官方參考手冊(cè)
1.解壓MySQL 5.7.20安裝包,如X:\MySQL\mysql-5.7.21-winx64。(是沒(méi)有data和my.ini的)
2.配置mysql的環(huán)境變量,創(chuàng)建MYSQL_HOME,并且在Path添加上%MYSQL_HOME%\bin;
3,配置my.ini. 并把my.ini放到bin目錄下(1.如果放在mysql-5.7.21-winx64 目錄下,在下面執(zhí)行net start mysql時(shí)可能無(wú)法啟動(dòng)MYSQL服務(wù)、2.不會(huì)自動(dòng)生成data)
[client] default-character-set=utf8 [mysqld] #解壓目錄 如:D:\MySQL\mysql-5.7.21-winx64 basedir = %MYSQL_HOME% #解壓目錄 如:D:\MySQL\mysql-5.7.21-winx64\data datadir = %MYSQL_HOME%\data port = 3306 default-character-set=utf8
4. 以管理員身份進(jìn)入命令行(可在小娜搜索輸入cmd找到),并進(jìn)入X:\MySQL\mysql-5.7.21-winx64\bin目錄下輸入命令:mysqld --initialize-insecure (生成無(wú)密碼的root用戶) 后,在mysql-5.7.20-winx64 目錄下就會(huì)出現(xiàn)data文件
5.再輸入mysqld --install,如果出現(xiàn)Service successfully installed 說(shuō)明注冊(cè)成功了。
注意:如果此操作報(bào)錯(cuò)Install/Remove of the Service Denied!,建議使用管理員身份進(jìn)入命令提示符
6.啟動(dòng)MySQL服務(wù),命令:net start mysql
7.設(shè)置密碼 mysqladmin -u root password 密碼
8.修改密碼方法如下 :接著輸入mysql -uroot -p 由于之前登陸過(guò),直接輸入剛才設(shè)置密碼(登錄root第一次是免密碼的直接回車(chē)進(jìn)入到) MYSQL>
接著輸入:update mysql.user set authentication_string=password('你想輸入的密碼') where user='root' and Host='localhost'; 然后接著再輸入: flush privileges;
9.輸入命令show databases; 查看數(shù)據(jù)表
