ERROR 2003 (HY000) Can't connect to MySQL server on 'localhost3306' (10061)Solution

This solution was prepared by me according to a series of methods on the Internet and suddenly succeeded, so I think it may be caused by its own instability

First of all, I downloaded the mysql file on the official website, and I can find how to download it anywhere on the Internet

After opening the file, I found that there is no my.ini

So I found a document and put it in there

[mysqld]# set port 3306port=3306# Set the installation directory of mysql ------- is your file path -------------basedir=F:mysql-8.0.27-winx64# Set the storage directory of the data of the mysql database --------- is your file path data folder created by yourself#datadir=F:mysql-8.0.27-winx64data# maximum number of connections allowedmax_connections=200# Allow connection failures.max_connect_errors=10# The character set used by the server defaults to utf8mb4character-set-server=utf8mb4# The default storage engine that will be used when creating new tablesdefault-storage-engine=INNODB# By default, the "mysql_native_password" plugin is used for authentication#mysql_native_passworddefault_authentication_plugin=mysql_native_password[mysql]# Set the default character set of the mysql clientdefault-character-set=utf8mb4[client]# Set the default port used by the mysql client to connect to the serverport=3306default-character-set=utf8mb4

Be careful not to copy, the file path is the path you downloaded yourself, and the data will be automatically generated when it is created, so just write the path, don't create it yourself, and don't change the name in the path, just call it data

p>

The next step is to initialize the My SQL database

Switch to the bin directory, I opened it directly as an administrator

Copy the following code in the MySQLbin directory

mysqld --initialize --console

If this happens to me, it means that the data has been created. If the data is deleted, it can run normally again. If the data cannot be deleted, you need to hold down win+r and then enter services.msc, press Enter to find mysql

Then close it, you can delete the data

If the run is successful, you will see a [email protected]: in the note on the last line...The latter is a random initial password, write it down

Enter after

net start mysql

It will appear that the service is starting and the service is successful

Enter later

mysql -uroot -p
Enter will ask you to enter the password, this is where I start 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)

The whole self-closing, the operation is done step by step, why is there a problem (although there were some small problems before, but I have reminded everyone of the configuration method I mentioned above) Then I started to find a way to findI couldn't find the reason for a morning, so I repeated the above operation, deleted the data, then restarted mysql in services.msc, and then entered net start mysql in the command prompt to restart the service, I found that it seems thatIn services, mysql is not started immediately. After entering net start mysql, it takes a while for mysql to start. When mysql starts, I enter mysql -uroot -p again, and enter a random password, and it suddenly succeeds

I think it may be that mysql does not start immediately after being prompted in the command prompt to successfully create, and you need to wait for the complete startup before you can enter the password and then enter

Change password

ALTER USER 'root'@'localhost' IDENTIFIED BY 'password you want to change';

Finally, I hope everyone can succeed once, and it crashes when I see n times of ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost:3306' (10061)

Let me introduce myself first. The editor graduated from Shanghai Jiaotong University in 2013. I worked in a small company and went to big factories such as Huawei and OPPO. I joined Alibaba in 2018, until now.I know that most junior and intermediate java engineers want to upgrade their skills, they often need to explore their own growth or sign up to study, but for training institutions, the tuition fee is nearly 10,000 yuan, which is really stressful.Self-learning that is not systematic is very inefficient and lengthy, and it is easy to hit the ceiling and the technology stops.Therefore, I collected a "full set of learning materials for java development" for everyone. The original intention is very simple. I hope to help friends who want to learn by themselves but don't know where to start, and at the same time reduce everyone's burden.Add the business card below to get a full set of learning materials
