看到这篇的同学应该是安装了新版本的mysql吧，新版本的mysql的密码初始化方式已经改了，

下面这个log就是安装mysql时候的输出，其中的红字就是密码初始化命令，

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

  ./bin/mysqladmin -u root password 'new-password'
  ./bin/mysqladmin -u root -h mysql1 password 'new-password'

Alternatively you can run:

  ./bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

  cd . ; ./bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

  cd mysql-test ; perl mysql-test-run.pl

WARNING: Found existing config file ./my.cnf on the system.
Because this file might be in use, it was not replaced,
but was used in bootstrap (unless you used --defaults-file)
and when you later start the server.
The new default config file was created as ./my-new.cnf,
please compare it with your file and take the changes you need.
