how to start mysql2 server?

Question

I am trying to get some open source code running on my local machine. It uses mysql2, and I have not used this database before. I had some errors I was able to fix by running:

sudo apt-get install libmysql-ruby libmysqlclient-dev

I start up the rails server but when I go to http://localhost:3000/ , I get the following error:

Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Do I need to start the MySQL server? How would I do that?

Answer 1

如果您已经安装了gem，请在运行$ rails server之前启动mysql。

$ mysql.server start

Answer 2

To install MySql database:

sudo apt-get install mysql-server

To start MySql server:

/etc/init.d/mysql start

To stop MySql server:

/etc/init.d/mysql stop

To restart MySql server:

/etc/init.d/mysql restart

To check the status of MySql server:

/etc/init.d/mysql status

Answer 3

There is no mysql2 server. mysql2 is the name of a MySQL client gem (Ruby library). All you need is to install and start MySQL server.

It seems your server is Debian or Ubuntu. Execute apt-get install mysql-server to install MySQL. Your MySQL server will automatically start (by Upstart on Ubuntu or sysinit on Debian).

Answer 4

Just type command on terminal

/opt/lampp/lampp start if you have lamp server.Please let me know is it working for you,either I'll do other thing.
