我下面进行一下填坑
由于MYSQL可以通过service启动，但是按照上述方法安装完后，无法通过service启动，因为service默认读取的是[mysql]属性下的内容，而且只读取my.cnf，所以需要用mysqld_multi进行多实例控制，上述讲解还有一个问题就是navicate无法访问，因为MYSQL8改变了密码保存方式，上面例子中的配置文件需要修改，上面包含的我就不再详述。还有一个问题
创建文件夹
mkdir -p /app/mysql/mysqldata/{3307/{data,tmp,binlog,innodb_ts,innodb_log,undo},backup,scripts}
mkdir -p /app/mysql/mysqldata/{3306/{data,tmp,binlog,innodb_ts,innodb_log,undo},backup,scripts}配置文件
为了使用mysqld_multi，需要3个配置文件，其中两个是用于初始化，另一个是用于mysqld_multi使用
my3306.cnf
