4.1 is an Alpha Test Edition, which is not produced as a fool installer or many inconvenience. However, I am quite like the distribution of compressed packages :) The following is the steps I have new installation and upgrade a 3.23.49.
A new installation
Use WinRAR to decompress files to c: / mysql directory (default directory, worry !!), execute under the command line
C: / mysql / bin / mysqld - ??? --install
Net Start MySQL
That is, it is very easy. If you are installed in other directories, remember to follow the path in the modified configuration file as before!
Second upgrade installation
Whether it is from 3.23.x upgrade or from 4.0.x upgrade!
First of all, you should still back up the old database, prepare a regret medicine to you! ! Then stop the current mysql database and remove it from the service. If WinMysqladmin is still running, it must be turned off! In addition to the Data directory, all version of the file is covered with the version of the version! Launch MySQL from the command line with c: / mysql / bin / mysqld-opt --skip-grant-tables, then execute C: / mysql / bin / mysql I looked at the header of this version, I feel stunned, I am interested in see you!
