yum install trace -y
strace mysql -uroot -p123456 -h xxxxx

这有什么关系么？这个不是mysql的吗？我只是用mysqltar包解压之后的bin/mysql命令 my.cnf只有在etc下面是有的。。其他路径怎么可能会有这个文件呢
my.cnf文件也没有什么内容
我找了一个正常的 这三个路径下也没有my.cnf文件。正常情况下除了etc目录下其他地方不可能有my.cnf文件的
我就是打眼一看这个比较多 
还没解决呢？不行就提BUG吧，哈哈
算了 ，不管了。搞了四五套测试环境就这一个有问题，怀疑是这个服务器之前安装其他环境影响的。不是新建的服务器。
里面是不是有mariaDB，要不卸载空，看看
从你的报错应该是密码没有输入进去，可以先通过navicat客户端看下系统表中的user表有没有设置固定的ip才可以访问
登录进去，重新建立一个用户，设置好密码，已经登录ip后在登录试试呢。
感觉密码没有输入进去
