启动mysql提示符

Question

我正在尝试使用mysql启动一个新的rails项目，但我遇到了mysql的困难。所以这就是我想要做的......

Rails new name -d mysql

然后我试试这个..

rake db:create

但它给了我以下错误..

    #<Mysql2::Error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)>
Couldn't create database for {"adapter"=>"mysql2", "encoding"=>"utf8", "pool"=>5, "username"=>"root", "password"=>nil, "host"=>"localhost", "database"=>"biller_development"}, {:charset=>"utf8", :collation=>"utf8_unicode_ci"}
(If you set the charset manually, make sure you have a matching collation)
#<Mysql2::Error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)>
Couldn't create database for {"adapter"=>"mysql2", "encoding"=>"utf8", "pool"=>5, "username"=>"root", "password"=>nil, "host"=>"localhost", "database"=>"biller_test"}, {:charset=>"utf8", :collation=>"utf8_unicode_ci"}
(If you set the charset manually, make sure you have a matching collation)

然后我试试这个..

mysql -uroot 

对于mysql提示符，但它说没有找到命令。我安装了mysql 5.6，我有mysql工作台。我该怎么办？任何帮助将不胜感激..

先谢谢
