2003-Can't connect to MySQL server (10060 unknow error) error occurs when using Navicat or other database management tools to connect to the remote mysql server
After investigation, it was found that it was a firewall problem, OK! Then write the processing process below
1. Check the status of the firewall
systemctl status firewalld
2. Open firewall ports (open port 3306 permanently)
sudo firewall-cmd --zone=public --add-port=3306/tcp --permanent
3. Overload firewall
sudo firewall-cmd --reload
For these three steps, the 2003 code error problem was basically solved, but when we linked, we found a 1045 Access denied for user'root'@'XX.XX.XX.XX' (using password: YES) error! What a shame! One wave has not settled, another wave rises again!
Then find a solution!
Don't worry if you encounter this problem, restart Navicat, you will have unexpected results! !
