编译安装都很顺利,到执行 bin/mysql_install_db --user=mysql 就报了usr/local/mysql/libexec/mysqld: unknown variable ‘innodb_data_home_dir

SQL可以正常用,但cmd启动不了mysql,报错[ERROR] unknown variable ;basedir=….问题 解决办法:将对应[mysql]下面的内容全部转移到【mysqld
在迁移网站的时候,大家往往都会使用宝塔一键迁移,但是确实也会面临一些问题,首先docker容器的资源无法进行转移,再者就是会报错,且网站无法访问: nginx: [emerg] unknown "connection_upgrade..." variable nginx: configuration file /www/server/nginx/conf/nginx.conf test failed 不太清楚为什么会出现这个错误,但是我找到了解决办法
