解决 Fatal error: Please read "Security" section of the manual to find out how to run mysqld

Posted 2022-12-07 袁义锐

问题的根源是使用root用户安装的mysql,使用默认启动./mysqld restart会报如下错误；

mysql安装目录为：/usr/local/mysql/

[root@SHB-L0120796 bin]# ./mysqld restart

暂时的解决办法：

在安装目录下/usr/local/mysql/bin使用root用户启动：./mysqld --user=root start  

./mysqld --user=root start

 

或者试试在安装目录下/usr/local/mysql/bin下面执行如下命令：

service mysqld start

 

最好的解决办法：在不修改my.cnf文件的情况下，执行如下命令行

./mysqld --skip-grant-tables --skip-networking --user=root &
