初始化mysql数据库失败的解决方法:第一寻到并打开my.ini文件;然后注释掉my.ini文件中的datadir;最后依据提醒把UTF8换成UTF8MB4即可。
数据库初始化时下令行涌现的报错如下:
C:\mysql-8.0.17-winx64\bin>mysqld --initialize --console 2019-08-24T13:33:22.622321Z 0 [System] [MY-013169] [Server] C:\mysql-8.0.17-winx64\bin\mysqld.exe (mysqld 8.0.17) initializing of server in progress as process 8404 2019-08-24T13:33:22.624188Z 0 [Warning] [MY-013243] [Server] --character-set-server: The character set UTF8MB3 is deprecated and will be removed in a future release.
