启动MySQL5.7时报错：initialize specified but the data directory has files in it. Aborting
解决方法：
vim /etc/my.cnf 查看文件，寻找datadir=... 查看到：datadir=/usr/local/mysql/data, 这个是data保存目录。 进入/usr/local/mysql/data后，查看到确实有数据： 将/usr/local/mysql/data备份， cd /usr/local/mysql mv data data.bak 接着执行： # mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
# systemctl start mysqld
启动MySQL5.7时报错:initialize specified but the data directory has files in it. Aborting.
