[mysqld]
#Base settings for mysql

socket=/var/lib/mysql/mysql.sock
user=mysql

#Coding settings for databases
default-character-set=utf8
character-set-server=utf8
collation-server=utf8_general_ci
init-connect="SET NAMES utf8"
skip-character-set-client-handshake

#Connections and package settings
wait_timeout=600
max_allowed_packet=64M

# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1

# Disabling symbolic-links is recommended to prevent assorted security risks;
# to do so, uncomment this line:
# symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

192.168.250.199:/.../settings.py

DATABASES = {                                                                                                                 
   'default': {

        'NAME'      : 'monika',#--a1--                                                                                        
        'USER'      : 'monika',#--a2--                                                                                        
        'PASSWORD'  : 'monika',#--a3--                                                                                        
        'HOST'      : '192.168.250.200',#--a4--                                                                                            
        'PORT'      : '3336',#--a5--                                                                                          
    }                                                                                                                         
}  

So I try to sync database by running 'python settings.py syncdb'

python manage.py syncdb

mysql>

It sucesseffuly! In Django project no more specific settings, and it work normaly using local database (yes, i have tried to put local my.conf on remote server - no effect).

  • no selinux, iptables and other security stuff
  • using redhat likely OS (CentOS and Scientific Linux)

I hope I have described my problem well. Thanks.

Was it helpful?

Solution

I think there is a mistake in your port number. If you want to leave it to default please leave the field as blank. Verify that you are entering the correct port number.
