Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
If your file my.cnf (usually in the /etc/mysql/ folder) is correctly configured with
socket=/var/lib/mysql/mysql.sock you can check if mysql is running with the following command:
mysqladmin -u root -p status try changing your permission to mysql folder. If you are working locally, you can try:
sudo chmod -R 755 /var/lib/mysql/ that solved it for me
Mysql2::Error Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
First, to find your socket file:
mysqladmin variables | grep socket For me, this gives:
| socket | /tmp/mysql.sock | Then, add a line to your config/database.yml:
development: adapter: mysql2 host: localhost username: root password: xxxx database: xxxx socket: /tmp/mysql.sock
