MySQL

Reset Root Password

sudo service mysql stop
sudo mysqld --skip-grant-tables &
mysql -u root mysql

UPDATE user SET Password=PASSWORD('[password]') WHERE User='root';
FLUSH PRIVILEGES;

Administer Users

[ip] can be an ip address, host name and % can be used as a wildcard.

CREATE USER '[user]'@'[ip]' IDENTIFIED BY '[password]';
DROP USER '[user]'@'[ip]';

Open Access

Instead of [db] and [table] can be *, which means any.

[privilege] can be ALL, USAGE, SELECT, etc.

You can optionally add WITH GRANT OPTION to the GRANT command for the user to be able to grant permissions.

See details .

GRANT [privilege] ON `[db]`.`[table]` TO '[user]'@'[ip]'
GRANT [privilege] ON *.* to '[user]'@'[ip]'
SHOW GRANTS for '[user]'@'[ip]';
REVOKE [privilege] ON *.* FROM '[user]'@'[ip]';
FLUSH PRIVILEGES;

Create a new DB

CREATE DATABASE `[name]` CHARACTER SET utf8 COLLATE utf8_general_ci;

Open Access to External Users

mysql -uroot -p[password] -e "GRANT ALL ON *.* to root@'%' IDENTIFIED BY '[password]' WITH GRANT OPTION; FLUSH PRIVILEGES;"
sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mysql/my.cnf
service mysql restart

Encoding

Check the Encoding

For a DB

SELECT default_character_set_name FROM information_schema.SCHEMATA WHERE schema_name = "[db_name]";

For Tables

SELECT CCSA.character_set_name FROM information_schema.`TABLES` T,
  information_schema.`COLLATION_CHARACTER_SET_APPLICABILITY` CCSA
WHERE CCSA.collation_name = T.table_collation
  AND T.table_schema = "[db]"
  AND T.table_name = "[table]";

For Columns

SHOW FULL COLUMNS FROM [table_name];

Change Collation for a DB

ALTER DATABASE [db] CHARACTER SET utf8 COLLATE utf8_general_ci;
ALTER TABLE [table] CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;

Add Timezone Info to a DB

mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -D mysql -u root -p
mysql -u root -p -e "flush tables;"

Installation of Services on Linux

Install a Service

Create file /etc/systemd/system/[name].service with contents:

[Unit]
Description=[Service Name]
After=syslog.target

[Service]
ExecStart=[command]
Restart=always
RestartSec=5s
KillSignal=SIGQUIT

[Install]
WantedBy=multi-user.target

Run

chmod 644 /etc/systemd/system/[name].service
systemctl daemon-reload

Samba

sudo apt-get install samba
sudo smbpasswd -a [user] # Set a password for your user in Samba
sudo nano /etc/samba/smb.conf

Add this to the end of the file:

[[name]]
path = [path]
available = yes
valid users = [user]
read only = no
browseable = yes
public = yes
writable = yes

sudo restart smbd

Stunnel4

Stunnel allows old devices which don’t support SMTP connections through SSL to support them.

sudo apt-get install stunnel4

sudo sed -i 's/ENABLED=0/ENABLED=1/g' /etc/default/stunnel4

openssl req -new -out mail.pem -keyout mail.pem -nodes -x509 -days 365
# (Common name - domain name)

sudo mv ~/mail.pem /etc/ssl/certs/mail.pem

sudo cp /usr/share/doc/stunnel4/examples/stunnel.conf-sample /etc/stunnel/stunnel.conf
sudo nano /etc/stunnel/stunnel.conf

Change:

cert = /etc/ssl/certs/mail.pem
sslVersion = all

Add config (for example):

[yandex-smtp]
client = yes
accept = 0.0.0.0:25
connect = smtp.yandex.ru:465

Management Commands

Data Migration Example

from django.db import migrations

def action(apps, schema_editor):
    [Model] = apps.get_model("[app]", "[Model]")

class Migration(migrations.Migration):
    dependencies = [
        ("[app]", "0001_initial"),
    ]

    operations = [
        migrations.RunPython(action),
    ]

Data Migration Example to Load Fixtures

from django.db import migrations
from django.core.management import call_command


def load_fixture(apps, schema_editor):
    # File name.json in fixtures dir
    call_command("loaddata", "[name]", app_label="[app]")


class Migration(migrations.Migration):

    dependencies = [
        ("[app]", "0001_initial"),
    ]

    operations = [
        migrations.RunPython(load_fixture)
    ]

How to Setup Internalization

Add to settings:

from django.utils.translation import ugettext_lazy as _
from os.path import dirname, join
SRC_DIR = dirname(dirname(abspath(__file__)))

LANGUAGES = (
    ("en", _("English")),
    ("ru", _("Russian")),
)

LOCALE_PATHS = (join(SRC_DIR, "locale"),)

TEMPLATES = [
    {
        "OPTIONS": {
            "builtins": ["django.templatetags.i18n"],
        },
    },
]

Add to templates:

{% trans 'text' %}
{% blocktrans %}Back to '{{ race }}' homepage{% endblocktrans %}

To create/update necessary .po files:

python manage.py makemessages -a

Install django-rosetta

You can then access your translations here — /rosetta

JavaScript

To create/update necessary .po files:

python manage.py makemessages -a -d djangojs

Add to urls.py

from django.views.i18n import JavaScriptCatalog

    url(r"^jsi18n/$",
        JavaScriptCatalog.as_view(packages=("moviesapp", ), domain="djangojs"),
        name="javascript-catalog"),

urlpatterns += [
    url(r"^jsi18n/$",
        JavaScriptCatalog.as_view(packages=("[app]", ), domain="djangojs"),
        name="javascript-catalog"),
]

Add to templates before any js code:

<script src="{% url 'javascript-catalog' %}"></script>

If you also need access to the language in js add:

{% get_current_language as LANGUAGE_CODE %}
<script>
  var language = "{{ LANGUAGE_CODE }}";
</script>

To use:

gettext("this is to be translated");
