After all the download is complete, start wamp, found that a service is not running.
First of all, this is not going to find which one is running, so we use the shortcut win + s, search for "service" and find meaning wamp beginning of that period.
Can be found mariadb is not running, then right-click Start on the finished thing, the strange thing is there's no port that appears when you first install occupied question, probably because local MYSQL uninstalled before I install a second time, port problems can try on their own, or Baidu search 0.0.
