mysql登录报错：ERROR 1045 (28000): Access denied for user root@localhost (using password: NO)

2019独角兽企业重金招聘Python工程师标准>>>

网上一大堆解决方法，这里只是补充。

网友给出的安全模式跳过权限表的解决方法：

# /etc/init.d/mysql stop
# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD(’newpassword’) where USER=’root’;
mysql> FLUSH PRIVILEGES;
mysql> quit
# /etc/init.d/mysql restart
# mysql -uroot -p
Enter password: <输入新设的密码newpassword>
mysql>

按照上述操作，出现以下问题：

一、执行 mysqld_safe 时，报错/usr/local/mysql/bin/mysqlld 找不到；

解决：将mysql的安装路径/mysql/bin下的mysqld链接至/usr/local/mysql/bin/mysqlld

#ln -s /server/mysql-5.5.37/bin/mysqld /usr/local/mysql/bin/mysqld

二、再次执行mysqld_safe发现mysql服务并没有启动起来；

解决：查看日志，发现【error】说是路径的问题；在mysql配置文件my.conf中添加：

basedir=/server/mysql mysql路径
datadir=/server/mysql/data mysql data路径
