==Install Moodle 2.6 using git==
 +
===Requirements===
 +
* Recommended minimum browser: recent Google Chrome, recent Mozilla Firefox, Safari 6, Internet Explorer 9 (IE 10 required for drag and drop of files from outside the browser into Moodle)
 +
* Moodle upgrade: Moodle 2.2 or later (if upgrading from earlier versions, you must upgrade to 2.2.11 as a first step)
 +
* Minimum DB versions: PostgreSQL 8.3, <span style="color:red;">MySQL 5.1.33</span>, MariaDB 5.3.5, MSSQL 2005 or Oracle 10.2
 +
* Minimum PHP version: <span style="color:green">PHP 5.3.3</span> (always use latest PHP 5.4.x or 5.5.x on Windows - http://windows.php.net/download/)
 +
* New recommended PHP extensions: <span style="color:green">zlib</span>, <span style="color:red;">OPcache</span>
 +
 
 +
====DB Version====
 +
SME Server 8.x comes with MySQL v5.0.95.  In order to install Moodle without risking destabilizing a SME server by changing the MySQL version, you can install MariaDB 5.3.54 ''alongside'' MySql.
 +
 
 +
====OPcache====
 +
Zend OPcache is built-in to PHP 5.5, and can be compiled to work with PHP 5.3.3. 
  
−
#
+
I have not been able to find a source online for an RPM for OPcache.
−
# http://wiki.contribs.org/Moodle
 
−
#
 
−
# Manual Process
 
  
−
    # create ibay 'moodle'
+
I believe this will make Moodle run more slowly than it would *with* OPcache.
  
−
    # fix ibay settings & permissions
+
===Installation===
 +
====Prepare your server====
 +
======Install useful php modules======
 +
* During installation, Moodle will request php-soap, php-xmlrpc and php-intl.  These are all available from the 'smeaddons' repository, and can be installed using:
 +
yum install php-soap php-xmlrpc php-intl
  
−
IBAY=moodle
+
=====Create an ibay=====
 +
* Create an ibay named 'moodle' in server-manager
 +
* Customize some of the settings on the new moodle ibay
 +
<nowiki>IBAY=moodle

===Notes on check_earlytalker===
+
=====Correct database settings if necessary=====
 +
If you were not prompted for database socket, port, or other connection settings during the command line setup, you will need to correct the settings manually.
 +
 
 +
The database connection settings are stored in this file:
 +
/home/e-smith/files/ibays/moodle/html/config.php
 +
 
 +
If you have just run the above database connection commands in the same putty session, you can correct your moodle settings using:
 +
<nowiki>IBAY=moodle
 +
sed -i  s/dbname.*/dbname\ \ \ \ \=\ \'$DBNAME\'\;/  /home/e-smith/files/ibays/$IBAY/html/config.php
 +
sed -i  s/dbuser.*/dbuser\ \ \ \ \=\ \'$DBUSER\'\;/  /home/e-smith/files/ibays/$IBAY/html/config.php
 +
sed -i  s/dbpass.*/dbpass\ \ \ \ \=\ \'$DBPASS\'\;/  /home/e-smith/files/ibays/$IBAY/html/config.php</nowiki>
 +
 
 +
====Optional Settings====
 +
=====Scan Uploads using ClamAV=====
 +
Moodle can be configured to scan all user files when uploaded.
 +
<nowiki>mysql $CONNECT  -e "use moodle;
 +
update mdl_config set value=1 where name='runclamonupload';
 +
update mdl_config set value='/usr/bin/clamscan' where name='pathtoclam';
 +
quit"</nowiki>
 +
=====Authentication Settings=====
 +
To configure authentication mechanisms:
 +
* Login to Moodle using an account with administrative rights
 +
* Select 'Site Administration'
 +
** Select 'Plugins'
 +
*** Select 'Authentication'
 +
Moodle can be configured to authenticate users using any of the methods listed below:
 +
* Manual accounts
 +
* No login
 +
* CAS server (SSO)
 +
* Email-based self-registration
 +
* External database
 +
* FirstClass server
 +
* IMAP server
 +
** Select 'imapcert' if your IMAP server uses a self-signed certificate
 +
* LDAP server
 +
* MNet authentication
 +
* NNTP server
 +
* No authentication
 +
* PAM (Pluggable Authentication Modules)
 +
* POP3 server
 +
* RADIUS server
 +
* Shibboleth
 +
* Web services authentication
 +
 
 +

Agent Configuration

Wazuh Client Installation Instructions

Wazuh 3.x installs correctly from the yum repository: 

yum --enablerepo=wazuh install wazuh-agent

Create the client account on the wazuh manager: 

/var/ossec/bin/agent-auth -m [ip.of.wazuh.server]

Replace "MANAGER_IP" with the IP address of the wazuh manager in this section of /var/ossec/etc/ossec.conf: 

...
<client>
    <server>
      <address>MANAGER_IP</address>
    </server>
    <config-profile>rhel, rhel6</config-profile>
</client>
...

Start the agent 

/etc/init.d/wazuh-agent start

SME Customizations

And restarted the agent using 

/etc/init.d/wazuh-agent restart

Mariadb notes moved to MariaDB_alongside_MySQL

Install Moodle 2.6 using git

Requirements

  • Recommended minimum browser: recent Google Chrome, recent Mozilla Firefox, Safari 6, Internet Explorer 9 (IE 10 required for drag and drop of files from outside the browser into Moodle)
  • Moodle upgrade: Moodle 2.2 or later (if upgrading from earlier versions, you must upgrade to 2.2.11 as a first step)
  • Minimum DB versions: PostgreSQL 8.3, MySQL 5.1.33, MariaDB 5.3.5, MSSQL 2005 or Oracle 10.2
  • Minimum PHP version: PHP 5.3.3 (always use latest PHP 5.4.x or 5.5.x on Windows - http://windows.php.net/download/)
  • New recommended PHP extensions: zlib, OPcache

DB Version

SME Server 8.x comes with MySQL v5.0.95. In order to install Moodle without risking destabilizing a SME server by changing the MySQL version, you can install MariaDB 5.3.54 alongside MySql.

OPcache

Zend OPcache is built-in to PHP 5.5, and can be compiled to work with PHP 5.3.3.

I have not been able to find a source online for an RPM for OPcache.

I believe this will make Moodle run more slowly than it would *with* OPcache.

Installation

Prepare your server

Install useful php modules
  • During installation, Moodle will request php-soap, php-xmlrpc and php-intl. These are all available from the 'smeaddons' repository, and can be installed using:
yum install php-soap php-xmlrpc php-intl
Create an ibay
  • Create an ibay named 'moodle' in server-manager
  • Customize some of the settings on the new moodle ibay
IBAY=moodle
/sbin/e-smith/db accounts setprop $IBAY \
FollowSymLinks enabled \
CgiBin enabled \
AllowOverride All \
Group www \
PublicAccess global \
PHPBaseDir "/home/e-smith/files/ibays/$IBAY/:/tmp/" \
UserAccess wr-group-rd-everyone
/sbin/e-smith/signal-event remoteaccess-update
#
mkdir /home/e-smith/files/ibays/$IBAY/moodledata
chown www:www /home/e-smith/files/ibays/$IBAY/moodledata
#
Create a database
  • Install Mariadb alongside mysql
  • create a mariadb database for moodle
# Generate a random 23 character password
DBPASS=`< /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c23`
DBNAME=moodle
DBUSER=moodle
CONNECT=--socket=/opt/mariadb-data/mariadb.sock
#
echo ;\
echo ;\
echo Creating Database using: ;\
echo DBNAME=$DBNAME ;\
echo DBUSER=$DBUSER ;\
echo DBPASS=$DBPASS ;\
echo ;\
echo Save this information!  You will need it later during initial application setup! \(press \<enter\> when ready\) ;\
read
#
mysql $CONNECT -e "create database $DBNAME; 
grant all privileges on $DBNAME.* to $DBUSER@localhost identified by \"$DBPASS\" with grant option;
quit"

Install Moodle

Download & Checkout using git
    #
    # Download moodle using git
    # http://docs.moodle.org/26/en/Git_for_Administrators#Obtaining_the_code_from_Git
    #
IBAY=moodle
cd /home/e-smith/files/ibays/$IBAY
mv html html.`date +%F-%H%M%S`
git clone git://git.moodle.org/moodle.git html
cd html
git branch -a
git branch --track MOODLE_26_STABLE origin/MOODLE_26_STABLE
git checkout MOODLE_26_STABLE
#
# correct ownership
signal-event ibay-modify $IBAY
Run the moodle installer
#
# run the moodle command line installer
# if prompted, set:
    # mysql port: 3307
    # mysql socket: /opt/mariadb-data/mariadb.sock
    #
cd /home/e-smith/files/ibays/$IBAY/html/admin/cli
sudo -u www /usr/bin/php install.php
Correct database settings if necessary

If you were not prompted for database socket, port, or other connection settings during the command line setup, you will need to correct the settings manually.

The database connection settings are stored in this file: 

/home/e-smith/files/ibays/moodle/html/config.php

If you have just run the above database connection commands in the same putty session, you can correct your moodle settings using: 

IBAY=moodle
sed -i  s/dbname.*/dbname\ \ \ \ \=\ \'$DBNAME\'\;/  /home/e-smith/files/ibays/$IBAY/html/config.php
sed -i  s/dbuser.*/dbuser\ \ \ \ \=\ \'$DBUSER\'\;/  /home/e-smith/files/ibays/$IBAY/html/config.php
sed -i  s/dbpass.*/dbpass\ \ \ \ \=\ \'$DBPASS\'\;/  /home/e-smith/files/ibays/$IBAY/html/config.php

Optional Settings

Scan Uploads using ClamAV

Moodle can be configured to scan all user files when uploaded. 

mysql $CONNECT  -e "use moodle;
update mdl_config set value=1 where name='runclamonupload';
update mdl_config set value='/usr/bin/clamscan' where name='pathtoclam';
quit"
Authentication Settings

To configure authentication mechanisms:

  • Login to Moodle using an account with administrative rights
  • Select 'Site Administration'
    • Select 'Plugins'
      • Select 'Authentication'

Moodle can be configured to authenticate users using any of the methods listed below:

  • Manual accounts
  • No login
  • CAS server (SSO)
  • Email-based self-registration
  • External database
  • FirstClass server
  • IMAP server
    • Select 'imapcert' if your IMAP server uses a self-signed certificate
  • LDAP server
  • MNet authentication
  • NNTP server
  • No authentication
  • PAM (Pluggable Authentication Modules)
  • POP3 server
  • RADIUS server
  • Shibboleth
  • Web services authentication

TiddlyWiki5 Using Node.js

TiddlyWiki is "a complete interactive wiki in JavaScript."


Warning.png Warning:
The install and update routines shown here are based on notes from a working installation.
The removal routines are untested.


Prerequisites

  1. node.js > 8.x (note: I was unable to find a binary installer for curent node releases; I use 'gcc' and compile locally)
  2. npm

Assumptions

  1. wiki content will be stored in /opt/tiddlywiki/tiddlers
  2. tiddlywiki code will be stored in /opt/tiddlywiki/node_modules
  3. tiddlywiki will run as user 'www'
  4. tiddlywiki logs will be run as 'smelog'
  5. tiddlywiki will be daemonized using daemontools

Installation

mkdir /opt/tiddlywiki
cd /opt/tiddlywiki
npm install tiddlywiki
chown -R www:www /opt/tiddlywiki/.

Create daemontools scripts, folders, etc

The code below is designed to be run by copy/paste into a server console prompt. 

mkdir -p /var/service/tiddlywiki/log
mkdir -p /var/log/tiddlywiki
chown -R smelog:smelog /var/log/tiddlywiki
cd /service
ln -s /var/service/tiddlywiki .
cd /var/service/tiddlywiki
touch down
    #
    # create the service 'run' file
    #
echo '#!/bin/sh
#
# setup node environment
#
exec 2>&1
#
APP_DIR=/opt/tiddlywiki
USER=www
#
NODE_EXEC=/usr/local/bin/node
NODE_ENV=production
NODE_CONFIG_DIR=$APP_DIR
NODE_APP=node_modules/tiddlywiki/tiddlywiki.js
NODE_ARGS=--server
echo "Starting $NODE_EXEC $APP_DIR/$NODE_APP $NODE_ARGS"
  cd $APP_DIR
  exec                             \
  setuidgid $USER                  \
  $NODE_EXEC $NODE_APP $NODE_ARGS
' > /var/service/tiddlywiki/run

    #
    # Create log/run
    #
echo '#!/bin/sh
#
exec                                    \
    /usr/local/bin/setuidgid smelog     \
    /usr/local/bin/multilog t s5000000  \
    /var/log/tiddlywiki' > /var/service/tiddlywiki/log/run

start the service

sv u tiddlywiki

check the log files to see if it worked

tail /var/log/tiddlywiki/current

Create init.d script and startup.shutdown scripts

This segment of code will create the scripts needed to start the service at boot and to stop the service at shutdown. 

SERVICE=tiddlywiki
#
cd /etc/rc.d/init.d
ln -s daemontools $SERVICE
cd /etc/rc.d/rc0.d
ln -s /etc/rc.d/init.d/e-smith-service K01$SERVICE
cd /etc/rc.d/rc1.d
ln -s /etc/rc.d/init.d/e-smith-service K01$SERVICE
cd /etc/rc.d/rc6.d
ln -s /etc/rc.d/init.d/e-smith-service K01$SERVICE
cd /etc/rc.d/rc7.d
ln -s /etc/rc.d/init.d/e-smith/service S99$SERVICE

Create config db entry

/etc/rc.d/init.d/e-smith-service will start a service whose status is enabled, and will not start it otherwise. 

SERVICE=tiddlywiki
config set $SERVICE service access public status enabled

Proxypass Domain for WAN access

I found that I needed to proxypass a domain. An alias/directory/location proxypass generated errors and prevented edits from saving correctly. 

DOMAIN=tiddlywiki.domain.tld
db domains set $DOMAIN domain Nameservers internet ProxyPassTarget http://localhost:8080/ TemplatePath ProxyPassVirtualHosts
#
# Several TiddlyWiki 5 Plugins require AllowEncodedSlashes On in httpd.conf
mkdir -p /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf/ProxyPassVirtualHosts
echo '# 
# AllowEncodedSlashes On from custom template in ProxyPassVirtualHosts
AllowEncodedSlashes On ' > /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf/ProxyPassVirtualHosts/04ProxyPassVirtualHosts
signal-event domain-create $DOMAIN

Update to the latest tiddlywiki code

cd /opt/tiddlywiki && setuidgid www npm update tiddlywiki && sv t tiddlywiki

COMPLETE Removal

DOMAIN=tiddlywiki.domain.tld
signal-event domain-delete $DOMAIN
db domains delete $DOMAIN
#
SERVICE=tiddlywiki
config delete $SERVICE
find /etc/rc.d -name "*$SERVICE*" -exec 'rm' -f "{}" \;
'rm' -rf /service/$SERVICE
'rm' -rf /var/service/$SERVICE
'rm' -rf /var/log/$SERVICE
#
cd /opt/$SERVICE
npm remove $SERVICE
cd /opt
'rm' -rf /opt/$SERVICE

Notes on check_earlytalker

Why did you remove the Request_for_deletion template on the check_earlytalker page? AFAIK it is obsolete and should be deleted according to http://forums.contribs.org/index.php/topic,46234.msg226418.html#msg226418 - — Cactus (talk | contribs)  07:05, 16 February 2012 (MST)

Here's my understanding of the Request_for_deletion addition to this page:

1) Piran posted a link to this page in a thread with the text "Install the check_earlytalker plugin": http://forums.contribs.org/index.php/topic,46229.msg226377.html#msg226377

2) Charlie noticed Piran's post, and assumed the wiki page described how to install check_earlytalker, so he made his post that the page is obsolete: http://forums.contribs.org/index.php/topic,46234.msg226418.html#msg226418

3) The page was updated with the 'Request_for_deletion' template

4) I added the reasoning to the 'talk' page outlining why the page is NOT obsolete (see below)

5) Over a year later, I removed the 'Request_for_deletion' template, assuming everyone had read and agreed with the reasoning I outlined on the 'talk' page.


Copied from http://wiki.contribs.org/Talk:Qpsmtpd_check_earlytalker - Unless there is more information elsewhere, I don't feel that this page is obsolete.

Despite the language used by piran in his mention of this page at http://forums.contribs.org/index.php/topic,46229.msg226377.html#msg226377, this page is not about adding check_earlytalker - which is included by default as mentioned by Charlie in the forum post referenced above.

This page is about: 

   Documenting the functionality of check_earlytalker (what it does and why it does it)
   Documenting how to change the timeout value applied by check_earlytalker
   Documenting how to monitor check_earlytalker to see if it is being used to deny email
