Steps and FAQs of connecting windows Navicat to Alibaba cloud server MySQL

Log in to your Alibaba cloud server first

 

 

 

  There are two more important , One is to configure the exit port ,

Another is to get your own public network ip  Connect to the server

I use it finalshell  Tool connection .

Mainly based on docker install mysql , Now my server docker Already installed , It's easy to install . There are many detailed steps on the Internet , Just run it once

Docker Configuration installation in MySQL_tuziailuobo_lee The blog of -CSDN Blog _docker install mysql To configure Time ：2022-04-13 author ：tuziailuobo brief introduction ： stay Docker Install in MySQL And configure , Mount the data locally Docker Configuration installation in MySQL explain ： It is installed by default docker, The environment is Alibaba cloud ubuntu20, Alibaba cloud security group is open 3306 port .1、 download MySQL Mirror image docker pull mysql:5.72、 establish MySQL The container mounts data at the same time docker run -d --restart=always --name mysql02 -p 3306:3306 -v /home/mysql.https://blog.csdn.net/qq_40716436/article/details/124149033?ops_request_misc=&request_id=&biz_id=102&utm_term=docker%E5%AE%89%E8%A3%85mysql&utm_medium=distribute.pc_search_result.none-task-blog-2~all~sobaiduweb~default-5-124149033.142^v30^pc_rank_34,185^v2^control&spm=1018.2226.3001.4187

 

I also wrote an article myself . But it doesn't matter  , It is important to pay attention to several points after installation

Look at the mirror image

docker images

But it doesn't matter whether you look or not , It will be pulled automatically anyway

Look at the container

docker ps

 

 

Follow the command and run again , Then check it out mysql Successful operation . If mysql Successfully run . Use navicat Connect

 

Okay , Half the water .  navicat  There are several common errors in connection

2005 - Unknown MySQL server host '45.130.63.101' (11001) "

This error should be reported by the server ip incorrect

2003 - Can't connect to MySQL server on '47.100.68.107' (10060 "Unknown error")

Maybe the port is not open

Remember to open the server port . This port is not necessarily 3306 . It's up to you to start docker Container time . Mapped port

But half of them are 3306 

 

 1045 - Access denied for user 'root'@'117.147.47.90' (using password: YES).

  After the port is opened , Change a wrong one .ip I'm too lazy to hide .  This port is more general . Maybe the account and password are wrong . It may also be that the account does not allow remote access .

Enter the container first . Remember to change the name of your container . Specified when creating containers

  Sign in mysql

 Welcome to the MySQL monitor.  See this to prove the account password , That's all right. . If navicat  I logged in with this account and password , Still there 1045 . That is the problem of account authorization .

# Add remote login user ------- 8.0 Previous 
# first root Represents the user name ,% All computers can be connected , You can also set a ip Address run connection , the second root The password 
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;

# Refresh MySQL System authority related table of 
flush privileges;


# View all users （ user name 、 Who is authorized to ）
SELECT user,host FROM mysql.user;

I used to give root Account authorized , But it still seems 1045 . no way

 SELECT user,host FROM mysql.user;

It may be the reason why I didn't do well . Later, I created another user silence . Can successfully access .

Let me create another account .

A lot of things , In fact, it is to create users , Authorize remote access . My username here is silence1

CREATE USER 'silence1'@'%' IDENTIFIED WITH mysql_native_password BY '123456';

 GRANT ALL PRIVILEGES ON *.* TO 'silence1'@'%';

 

 

Okay . Connected
