启动mysql服务
service mysqld start
mysql
找了网上的教程，在my.cnf中加入 user=mysql也不行
如何才能进入mysql
mysqladmin -u root password "新密码"
mysql -uroot -pmysql5.7会在安装完后给你随机生成一个密码，在安装日志里会有...
mysql5.7.10刚安装好，会生成一个随机密码。
如果没记住这个随机密码，那么到mysql/bin/下执行mysql_secure_installation命令
按照提示重置密码和其他选项。
ps：找了一下午终于找到方法了！！！
1、编辑/etc/my.cnf
在[mysqld] 配置部分添加一行
skip-grant-tables
mysql -u root
