Vsftpd¶

# configuration of vsftpd

http://www.basicconfig.com/linuxnetwork/ftp_server#check-vsftpd http://wiki.ubuntuusers.de/vsftpd

# Example config file /etc/vsftpd.conf
#
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=NO
#
# Uncomment this to allow local users to log in.
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
# default
local_umask=022
#
#
#
# Uncomment this to allow the anonymous FTP user to upload files. This only has an effect if the above global write enable is activated. Also, you will obviously need to create a directory writable by the FTP user.
#anon_upload_enable=YES
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
#
# Activate logging of uploads/downloads.
xferlog_enable=YES
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES
#
# If you want, you can arrange for uploaded anonymous files to be owned by a different user. Note! Using "root" for uploaded files is not
# recommended!
#chown_uploads=YES
#chown_username=whoever
#
# You may override where the log file goes if you like. The default is shown
# below.
xferlog_file=/var/log/vsftpd.log
#
# If you want, you can have your log file in standard ftpd xferlog format. Note that the default log file location is /var/log/xferlog in this case.
xferlog_std_format=YES
#
# You may change the default value for timing out an idle session.
#idle_session_timeout=600
#
# You may change the default value for timing out a data connection.
#data_connection_timeout=120
#
# It is recommended that you define on your system a unique user which the ftp server can use as a totally isolated and unprivileged user.
nopriv_user=ftpsecure
#
# Enable this and the server will recognise asynchronous ABOR requests. Not recommended for security (the code is non-trivial). Not enabling it,
# however, may confuse older FTP clients.
#async_abor_enable=YES
#
# By default the server will pretend to allow ASCII mode but in fact ignore the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.
#ascii_upload_enable=YES
#ascii_download_enable=YES
#
# You may fully customise the login banner string:
#ftpd_banner="_____________________________________Welcome to my ftp Site!_____"
#
# customize your login
banner_file=/etc/vsftpd.banner_file
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd.banned_emails
#
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
# (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
# the user does not have write access to the top level directory within the
# chroot)
# dangerous don't use it
chroot_local_user=NO
chroot_list_enable=YES
passwd_chroot_enable=YES
chroot_list_file=/etc/vsftpd.chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by
# default to avoid remote users being able to cause excessive I/O on large
# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
# the presence of the "-R" option, so there is a strong case for enabling it.
ls_recurse_enable=YES
#
# When "listen" directive is enabled, vsftpd runs in standalone mode (rather
# than from inetd) and listens on IPv4 sockets. To use vsftpd in standalone
# mode rather than with inetd, change the line below to 'listen=YES'
# This directive cannot be used in conjunction with the listen_ipv6 directive.
listen=NO
#
# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
# sockets, you must run two copies of vsftpd with two configuration files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES

# Howto Setup Webdav (file transfer over http, like ftp)

I Prerequisites¶

http server (nginx)
webdav client (owncloud)

II Installation for Slackware¶

use slackpkg
use sbopkg
use SlackBuild scripts

III Configuration¶

# quick setup

setup nginx
setup owncloud

# setup nginx [1]

# global webdav, owncloud configuration

Databases¶

# configuration of different databeses

MariaDB¶

# Howto Setup MariaDB

I Prerequisites

mariadb-5.5.40-x86_64-2.txz
privileged user only for sql-data, mostly mysql

II Installation for Slackware

use slackpkg
use sbopkg
use SlackBuild scripts

III Configuration

Howto: http://docs.slackware.com/howtos:databases:install_mariadb_on_slackware

mysql_install_db –user=mysql

chown -R mysql.mysql /var/lib/mysql

chown 755 /etc/rc.d/rc.mysqld

/etc/rc.d/rc.mysqld start

mysqladmin -u root password ‘NEW_PASSWORD’

use phpmyadmin to manage databases

root@gamma:~# mysql_install_db --user=mysql
Installing MariaDB/MySQL system tables in '/var/lib/mysql' ...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:

'/usr/bin/mysqladmin' -u root password 'new-password'
'/usr/bin/mysqladmin' -u root -h gamma password 'new-password'

Alternatively you can run:
'/usr/bin/mysql_secure_installation'

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.

You can start the MariaDB daemon with:
cd '/usr' ; /usr/bin/mysqld_safe --datadir='/var/lib/mysql'

You can test the MariaDB daemon with mysql-test-run.pl
cd '/usr/mysql-test' ; perl mysql-test-run.pl

Please report any problems at http://mariadb.org/jira

The latest information about MariaDB is available at http://mariadb.org/.
You can find additional information about the MySQL part at:
http://dev.mysql.com
Support MariaDB development by buying support/new features from
SkySQL Ab. You can contact us about this at sales@skysql.com.

change permissions of /var/lib/pgsql/ to chown -R username:username
create database: su username -c “initdb -D /var/lib/pgsql/9.3/data –locale=de_DE.UTF-8 -A md5 -W”

root@host:~# su username -c "initdb -D /var/lib/pgsql/9.3/data --locale=de_DE.UTF-8 -A md5 -W" 
could not change directory to "/root": Permission denied
The files belonging to this database system will be owned by user "username".
This user must also own the server process.

The database cluster will be initialized with locale "de_DE.UTF-8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "german".

Data page checksums are disabled.

IV Running Djangoprojects¶

create a django project::

django-admin.py startproject mysite
create a database in postgresql (more stable as other databases) use phpPgAdmin
change database setting in settings.py
sync database and create the superuser for the djangoproject::

python manage.py syncdb
the most important ;-) start and test your application with gunicorn::

gunicorn mysite.wsgi:application

see: https://docs.djangoproject.com/en/1.4/howto/deployment/wsgi/gunicorn/ 6. create an app:

python manage.py startapp [appname]

etc.
