1. Looking for various installation packages, I used MYSQL archieved at first, and the result was successful. Later, I found the sharing of this friend on the Internet, which is really great http://download.csdn.net/download/hjj_yexufei/9588373
2. When installing, follow this step by step http://blog.csdn.net/fanyunlei/article/details/21454645, especially detailed!
3. During the installation process, because I didn't remember the root password, I didn't choose the modefy security option, and I couldn't get in when I used mysql later! Even started, I don't know what the modefy security option is for, this friend's question post helped me http://bbs.csdn.net/topics/392060418
4. Forgot the root password, reset the password according to this post http://www.cnblogs.com/andy_tigger/archive/2012/04/12/2443652.html
5. After resetting the password, there is a problem with logging in to the mysql command client. It is clear that the password is entered correctly, but it flashes back. Then this post helped solve the problem! http://blog.csdn.net/kenny_zhang1130/article/details/52033031, because the mysql service was closed in order to change the password before, the service was not opened later, so the client always crashes
