Error 2003 (HY000) can't connect to MySQL server on 'localhost3306' (10061) solution

This solution is based on a series of online methods to prepare for sudden success , So I think it may be caused by its instability

First , I downloaded it on the official website mysql file , You can find how to download it on the Internet

Then after opening the file , Found no my.ini

So I found a document and put it in

[mysqld]
#  Set up 3306 port 
port=3306
#  Set up mysql Installation directory    ---------- Is your file path -------------
basedir=F:mysql-8.0.27-winx64
#  Set up mysql Database data storage directory   --------- Is your file path data The folder is created by itself 
#datadir=F:mysql-8.0.27-winx64data
#  Maximum connections allowed 
max_connections=200
#  Number of connection failures allowed .
max_connect_errors=10
#  The character set used by the server defaults to utf8mb4
character-set-server=utf8mb4
#  The default storage engine that will be used when creating a new table 
default-storage-engine=INNODB
#  By default “mysql_native_password” Plug in authentication 
#mysql_native_password
default_authentication_plugin=mysql_native_password
[mysql]
#  Set up mysql Client default character set 
default-character-set=utf8mb4
[client]
#  Set up mysql The default port when the client connects to the server 
port=3306
default-character-set=utf8mb4

Be careful not to copy , The file path is your own download path ,data It will be generated automatically when it is created , So just write the path , Don't create it yourself , Don't change your name in the path , Call data

Then it's initialization My SQL database

Switch to bin Under the table of contents , I opened it directly as an administrator

stay MySQLbin Copy the following code under the directory

mysqld --initialize --console

If this happens to me, it means data It has been created , Deleted data It can run normally again , If data If you can't delete it, you need to press and hold win+r Then input services.msc, Enter to find mysql

Then close it , You can delete data 了

If it runs successfully , It will be on the last line note I saw one in the r[email protected]：... The following is the random initial password , Write him down

After input

net start mysql

The service is starting and the service is successful

Then type

mysql -uroot -p
Enter and you will be asked to enter the password , This is where I began to have a headache , Every time I enter the password, it will appear

ERROR 2003 (HY000): Can’t connect to MySQL server on ‘localhost:3306’ (10061)

It's completely autistic , The operation is step by step. Why do problems occur （ Although there were some small problems before , However, the configuration method I mentioned above has reminded you ） Then I began to find a way , I've been looking for a whole morning, but I haven't found the reason , So I repeat the above operation , take data Deleted , And then restart in services.msc Restart in mysql, Then enter... At the command prompt net start mysql Restart the service , I find it seems to be services in ,mysql It is not started immediately , Input net start mysql After that, I need to wait for a while ,mysql Will start , etc. mysql Launched the , I'll type it again mysql -uroot -p, Enter the random password and suddenly succeed

I think it may be after the prompt of successful creation in the command prompt ,mysql It didn't start immediately , You can enter the password and then enter after the successful startup

Change Password

ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘ The password you want to change ’;

Finally, I hope everyone can succeed at once , notice n many times ERROR 2003 (HY000): Can’t connect to MySQL server on ‘localhost:3306’ (10061) It's quite collapsed
