Cann't connect to remote mysql server?

Added by Jeff W about 6 years ago

My fresh installation Redmine keeps saying "Can't connect to MySQL server on '192.168.1.103'...", even though mysql client connection is fine and "ruby script/rails server webrick -e production" is also fine. Is there any thing I'm missing? How I can name the environment to 'production' with HTTPD?

database.yml config is below:
-------------------------------
production:
adapter: mysql2
database: redmine
host: 192.168.1.103
username: redmine
password: xxxxxxx
encoding: utf8
port: 3306

\#development:
\# adapter: mysql2
\# database: redmine_development
\# host: localhost
\# username: root
\# password: ""
\# encoding: utf8

Error information:
-------------------------------
Can't connect to MySQL server on '192.168.1.103' (13) (Mysql2::Error)

All right, I figured it out, SELinux was the bad guy!
