mysql安装（windows x64）
换电脑重装了下环境，这里记录下以备查询。
mysql 8.0.20+不需要手动建立my.ini和datadir，管理员运行cmd（非管理员可能遇到一些问题），进入mysqlin下。
执行命令mysqld --initialize --console
这里可能会报错
这个是缺微软常见运行库，如截止2019年7月提取码：rr0h
也可以去网上找比较新的运行库。

安装流程
请务必按照流程进行
1.安装navicat，但是不要打开（不然可能在生成激活码时候会报rsa public key not found的错
2.打开keygen，先点patch（应该是自动找到的，提示cracked！成功；
3.点生成秘钥生成序列号的生成按钮
4.出现序列码后打开navicat激活界面贴上
5.在弹出窗口点手动激活，把请求码贴到keygen中，然后生成激活码，贴到navicat激活框中，完毕。
