I installed mysql in the debian system in a hurry and asked Baidu no one knows! -- Debian information of the Linux release-the following is a detailed description. I only have 30 points in total to solve the following two problems and give 30 points. Be sure to give them to the point. Don't send me the error code and the corresponding problems. Thank you,


The following error message is displayed when mysql is installed in debian:
Checking for processing upt, not cleanly closed and upgrade meeding tables ..
Some people on the Internet say that this prompt is okay. I don't know how to solve this prompt?


Another problem is that the client cannot connect to the mysql server In debian. the following error occurs: Error 2003 cannot connect to the mysql server *. * (10061)
How can this problem be solved? No positive solution can be found on the Internet.
Note skip-networking out. This cannot be found in my. cnf.
Tip:
Instead of skip-networking the default is now to listen onlyon
