解决Windows环境下安装mysql-8.0.11-winx64遇到的问题

再次执行上面命令，会打印用户的初始密码，其中@localhost : XXXXXX就是默认密码，需要记住，如果没有记住，就将后来生成的data文件删除，再次生成也是可以的

F:\mysql\mysql-8.0.11-winx64\bin>mysqld --initialize --console
2018-10-29T09:28:49.177043Z 0 [System] [MY-013169] [Server] F:\mysql\mysql-8.0.11-winx64\bin\mysqld.exe (mysqld 8.0.11) initializing of server in progress as process 12980
2018-10-29T09:29:19.270535Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: kw3AlnY_g.Dg
2018-10-29T09:29:41.684599Z 0 [System] [MY-013170] [Server] F:\mysql\mysql-8.0.11-winx64\bin\mysqld.exe (mysqld 8.0.11) initializing of server has completed

3、然后安装服务， mysqld --install[服务名] 如果只有一个服务可以不写默认mysql,如果多个服务可以写具体的服务名称，XXXX，当回车之后，又出现错误， install/remove of the service deined,这是由于运行cmd的时候不是用管理员的身份运行的，只要再次以管理员的命令运行cmd就可以了,出现service successfully installed 说明服务安装好了。

F:\mysql\mysql-8.0.11-winx64\bin>mysqld --install
Service successfully installed.

4、启动服务，运行命令 ： net start mysql ，看到服务已经启动成功

F:\mysql\mysql-8.0.11-winx64\bin>net start mysql
MySQL 服务正在启动 ....
MySQL 服务已经启动成功。

5、更改密码和密码认证插件 ，

在MySQL安装目录的 bin 目录下执行命令：mysql -u root -p

F:\mysql\mysql-8.0.11-winx64\bin>mysql -u root -p
Enter password: *******
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

这时要重新生成密码，删除data目录，运行mysqld --initialize --console,

F:\mysql\mysql-8.0.11-winx64\bin>mysqld --initialize --console
2018-10-29T10:04:23.337650Z 0 [System] [MY-013169] [Server] F:\mysql\mysql-8.0.11-winx64\bin\mysqld.exe (mysqld 8.0.11) initializing of server in progress as process 7928
2018-10-29T10:05:19.210237Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: RXZG!fJR2Ly+
2018-10-29T10:06:00.603070Z 0 [System] [MY-013170] [Server] F:\mysql\mysql-8.0.11-winx64\bin\mysqld.exe (mysqld 8.0.11) initializing of server has completed

重新执行mysql -u root -p，填入密码（注意密码左右没有空格），这时会打印出相关的信息

F:\mysql\mysql-8.0.11-winx64\bin>mysql -u root -p
Enter password: ************

修改用户密码，在MySQL中执行命令：ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '新密码';,出现下面情况就证明你已经修改成功。

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '5502yulijian.';
Query OK, 0 rows affected (0.17 sec)

show databases; (‘；'一定要加）

这样就可以了
