Install

Printer-friendly versionSend to friendPDF version

# First make sure the system is up to date.

sudo apt-get update

apt-get update
apt-get dist-upgrade

# A quick and dirty way of setting up a lot of dependencies:

apt-get install phpmyadmin mysql-server
hostname -i

# note your IP address above, and go to http://xxx.xxx.xxx.xxx/ should be 127.0.0.1 if localhost on your laptop for instance!
# It works!

 

if problem with phpmyadmin, ie http://localhost/phpmyadmin error:

edit the file /etc/phpmyadmin/apache.config

in the bottom part of the doc there is this:

# Authorize for setup
<Directory /usr/share/phpmyadmin/setup>
<IfModule mod_authn_file.c>
AuthType Basic
AuthName "phpMyAdmin Setup"
AuthUserFile /etc/phpmyadmin/htpasswd.setup
</IfModule>
Require valid-user
</Directory>

# Disallow web access to directories that don't need it
<Directory /usr/share/phpmyadmin/libraries>
Order Deny,Allow
Require valid-user--------------------here there was as Deny from All---------------
</Directory>
<Directory /usr/share/phpmyadmin/setup/lib>
Order Deny,Allow
Require valid-user--------------------same as above--------------------------------
</Directory>

then

Does /etc/apache2/conf.d/phpmyadmin.conf exist? If not, does /etc/phpmyadmin/apache.conf exist?


If phpmyadmin.conf exists, then you can try to remove it: sudo rm phpmyadlin.conf

If the first doesn't exist and the second does, try:

sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf.d/phpmyadmin.conf
sudo /etc/init.d/apache2 restart

cd /var/www
rm index.html
echo '<?php phpinfo();' > info.php
/etc/init.d/apache2 restart

# Now go to http://xxx.xxx.xxx.xxx/info.php
# phpinfo() is cool!
# Now we'll get a git checkout of pressflow

apt-get install git-core
cd /var
rm -Rf www
git clone git://github.com/pressflow/6.git www
cd /var/www
echo '<?php phpinfo();' > info.php

# Restore our phpinfo(); file.

cd /var/www/sites/default/
cp default.settings.php settings.php
mkdir files
chown www-data *

apt-get install postfix

# postfix is a mail server; so drupal can email account info to us

mysql -u root or

mysql -h 127.0.0.1 -u root -p

http://www.debuntu.org/how-to-create-a-mysql-database-and-set-privileges...

http://portalbuilders.pro/PBblog/?p=493

 

Create a mysql database

 

 

 

mysql> CREATE DATABASE database1;

 

 

Create a mysql user

For creating a new user with all privileges (use only for troubleshooting), at mysql prompt type:

mysql> GRANT ALL PRIVILEGES ON *.* TO 'yourusername'@'localhost' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION;

For creating a new user with fewer privileges (should work for most web applications) which can only use the database named "database1", at mysql prompt type:

mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES ON database1.* TO 'yourusername'@'localhost' IDENTIFIED BY 'yourpassword';

 

 

 

 

# In mysql, create a database for the drupal site.
# Then go to http://xxx.xxx.xxx.xxx/install.php
# Use root user, no pass and that database to get an install working.

a2enmod rewrite
/etc/init.d/apache2 restart

# Enabling mod_rewrite for Apache allows us to use clean urls.
# Now let's set up Drush:

apt-get install php5-cli
cd /opt/
git clone --branch 7.x-4.x http://git.drupal.org/project/drush.git
ln -s /opt/drush/drush /usr/local/bin/drush

# Drush lives in /opt, is symlinked into /usr/local/bin so we can use it.

sudo apt-get install drush

cd /var/www/
drush status

# Verify that Drush works by running drush status.

nano /etc/php5/cli/conf.d/mcrypt.ini

# Fix the first comment line in this ini file to get rid of warning message.

cd /var/www/
drush dl devel
drush en -y devel devel_generate

# Now we went back to the Drupal admin interface and used devel_generate.
# We created 50 users, 50 categories and 50 nodes with some comments.

# Now, baseline benchmarking with no caching at all:

ab -n 1000 -c 30 http://xxx.xxx.xxx.xxx/

# Now for APC:
cd /var/www
apt-get install php-apc
cp /usr/share/doc/php-apc/apc.php.gz ./
gunzip apc.php.gz
/etc/init.d/apache2 restart

# Now visit http://xxx.xxx.xxx.xxx/apc.php and be sure it's working.
# Then rerun benchmarks:

ab -n 1000 -c 30 http://xxx.xxx.xxx.xxx

# Now go back into the Drupal admin interface and enable normal page cache.
# http://xxx.xxx.xxx.xxx/admin/settings/performance
# And benchmark again:

ab -n 1000 -c 30 http://xxx.xxx.xxx.xxx

# Should be looking pretty good, but the system will be under heavy load
# if we ask it to consistently deliver 100s of caches pages a second.
# Next level: use Varnish.

apt-get install varnish
cd /etc/apache2/
nano ports.conf

# Change apache to listen on port 8080

nano sites-available/default

# Change the virtualhost to also listen on port 8080

/etc/init.d/apache2 restart

# Now verify that the site is up via Apache at http://xxx.xxx.xxx.xxx:8080/

nano /etc/varnish/default.vcl

# Next change the Varnish configuration to enable and listen on port 80.
# Change the "start" value at the top of the file from "no" to "yes".
# Then check in the "Alternative 2, Configuration with VCL" section. Set the line
# DAEMON_OPTS="-a :6081  to use -a :80

/etc/init.d/varnish restart

# Verify that you get the site via http://xxx.xxx.xxx.xxx/
# Using firebug or Chrome dev tools, or live HTTP Headers you can verify that
# the via-varnish and "age" headers are being set.

# Now go turn the page caching to "external". And run benchmarks again:

ab -n 1000 -c 30 http://xxx.xxx.xxx.xxx/

# Whoops too fast, let's do more requests:

ab -n 10000 -c 30 http://xxx.xxx.xxx.xxx/

# What about a higher amount of concurrency?

ab -n 10000 -c 100 http://xxx.xxx.xxx.xxx/

# Wow. Varnish is cool. :)
# Just to be sure, review the old site is still the same/slow:

ab -n 1000 -c 30 http://173.203.106.74:8080/

# Now let's check it as a logged in user by pulling the session cookie out of
# Firebug, Chrome developer plugin, or Live Http Headers.

ab -C 'SESS3bcc84522751c15bbe6faf2b284d6c5a=gp7fuh9lvui6b86ffr221r6e85' -n 1000 -c 30 http://173.203.106.74/

# That should be about the same as anonymous users; not too many modules.
# Let's add a module that impacts logged-in user performance.

cd /var/www
drush dl admin_menu
drush en admin_menu
ab -C 'SESS3bcc84522751c15bbe6faf2b284d6c5a=gp7fuh9lvui6b86ffr221r6e85' -n 1000 -c 30 http://xxx.xxx.xxx.xxx/

# Now lets install memcached

apt-get install memcached
apt-get install php5-memcached
cd /var/www
drush dl memcache
cd /var/www/sites/default/
nano settings.php

# Add these lines to the bottom, without the leading #hashmarks of course:
#    $conf['cache_inc'] = 'sites/all/modules/memcache/memcache.inc';
#    $conf['memcache_bins'] = array('cache_form' => 'database');
#
# Then restart apache and verify the site is still up and running.

/etc/init.d/apache2 restart

# Let's verify that memcached is doing stuff:

apt-get install telnet
telnet localhost 11211

# You can run "stats" to see statistics. Note cache_gets vs cache_hits.
# This is an important ratio.
#
# Type "quit" to get out.

# Now apachesolr.

cd /var/www
drush dl apachesolr
cd /var/www/sites/all/modules/apachesolr/

# The README file in the module has good instructions.
# This will grab the PHP client, the java server and set up the example solr
# server using the .xml schema file provided by the Drupal module.
cat README.txt
apt-get install subversion
svn export -r22 http://solr-php-client.googlecode.com/svn/trunk/ SolrPhpClient
cd /opt
wget http://download.filehat.com/apache//lucene/solr/1.4.1/apache-solr-1.4.1.tgz
tar -xzvf apache-solr-1.4.1.tgz
cd apache-solr-1.4.1/example/solr/conf/
cp /var/www/sites/all/modules/apachesolr/*.xml ./
cd ../..
nohup java -jar start.jar &
cd /var/www/
drush en apachesolr_search
drush cron

# We should be able to verify that our documents are being indexed now.

# Next up, let's use a better varnish config to allow Google Analytics:
cd /etc/varnish/
mv default.vcl default.vcl.bak
nano default.vcl

# Use the config from :
# https://wiki.fourkitchens.com/display/PF/Configure+Varnish+for+Pressflow
# And test its syntax first:

/usr/sbin/varnishd -d -f default.vcl

# Then restart varnish to have it take effect:

/etc/init.d/varnish restart

# Now debuggging with backtraces

apt-get install php5-xdebug graphviz ghostscript
nano /etc/php5/conf.d/xdebug.ini

# Set xdebug.profiler_enable_trigger = 1 in xdebug.ini

/etc/init.d/apache2 restart
cd /opt/
svn co http://xdebugtoolkit.googlecode.com/svn/tags/0.1.5/xdebugtoolkit/ xdebugtoolkit
ln -s /opt/xdebugtoolkit/cg2dot.py /usr/local/bin/cg2dot.py

# Now we have the tool ready. Hit http://xxx.xxx.xxx.xxx/index.php?XDEBUG_PROFILE=1

ls -l /tmp/

# See that theres's a cachegrind.out fiile in /tmp
# Then make it into an svg file:

cg2dot.py /tmp/cachegrind.out.21700 > /tmp/grind1.dot
dot /tmp/grind1.dot -Tsvg -o /var/www/grind1.svg

# Hit http://xxx.xxx.xxx.xxx/grind1.svg to view
# We can also use webgrind:

cd /var/www/
get clone https://github.com/jokkedk/webgrind.git

# Now: http://xxx.xxx.xxx.xxx/webgrind

# Munin is a nice easy monitoring tool: apt-get install munin
