MySQL在Windows上安装多个实例的方法

MySQL在Windows上安装多个实例的方法

Step 1: 解压MySQL安装包，配置my.ini文件，注意port不能设置为默认的3306，这里我们设置为3307端口：

basedir = E:\MySQL\mysql-5.7.17-win32 datadir = E:\MySQL\mysql-5.7.17-win32\data log_bin server_id=5717 port = 3307

Step 2: 打开CMD窗口，进入到安装路径的bin目录，这里为：E:\MySQL\mysql-5.7.17-win32\bin，执行如下命令：

mysqld --initialize-insecure mysqld install MySQL5711

Step 3:  执行成功后启动MySQL，并更新相应的密码，注意这里的初始密码为空

mysql -uroot -P3307 -p update mysql.user set authentication_string=password("lhr") where user="root"; update mysql.user set Host="%" where Host="127.0.0.1"; update mysql.user set Host="%" where Host="localhost"; flush privileges

Step 4:  验证登录：mysql -uroot -plhr -P3307

E:\MySQL\mysql-5.7.17-win32\bin>mysql -uroot -plhr -P3307 mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g.
