How to install the MySQL database in the Linux operating system

First hit me is the RPM installation, it tells me that the MySQL version of the conflict, the installation can not continue. After I use the rpm-q query, I want to delete the system with the RPM-E version (3.x.x), but the RPM and mercilessly returned a lot of other errors, due to the other software and some association, the 3.x.x can not be deleted. The good feeling of the original RPM, in this moment disappeared without a trace.

"Three-person line, there will be my teacher." "I immediately went to MSN to find Alin, when I asked him how to uninstall MySQL or upgrade with RPM, this guy would gloat to tell me that he upgraded it in 1 minutes with that Debian, and finally told me that he was" not "using RPM, and then he kept on laughing. I know ya revenge me, the last time I kept recommending that "Debian", I have not dumped him, this will give him a chance. In fact, I also think "Debian" is good, it is too harsh to read.

Since the RPM can not continue, we have to return to the second. I chose the binary installation package this time. And then find a pioneer in Google to install notes, as a reference. Then along the footsteps of the predecessors quickly walked a bit, and black and blue was bounced back, the experience of the predecessors is not suitable for me, it seems that the world did not have silver bullets.

It seems that the impatient is unable to solve the problem, simply calm down, and found a lot about MySQL installation introduction article. After many attempts, finally found a path in the thorn bushes ...
