Install WordPress on Ubuntu virtual server at Media Temple

May 25, 2011

Server is a MediaTemple “ve” server which is a Parallels Virtuozzo container with Ubuntu 10.04 LTS Lucid installed as the operating system. The first step is to install packages:


apt-get update
apt-get install mysql-server
apt-get install apache2
apt-get install php5
apt-get install php5-mysql

apt-get update

apt-get install mysql-server

apt-get install apache2

apt-get install php5

apt-get install php5-mysql

Now set mysql service to start automatically:


update-rc.d mysql defaults
service mysql start

update-rc.d mysql defaults

service mysql start

Next create a database for wordpress:


mysql -p -u root
create database wordpress;
grant all privileges on wordpress.* to 'wordpress'@'localhost' identified by 'YOURNEWPASS';
flush privileges;
exit;

mysql -p -u root

create database wordpress;

grant all privileges on wordpress.* to 'wordpress'@'localhost' identified by 'YOURNEWPASS';

flush privileges;

exit;

Next we’ll download and install wordpress:


cd /root
wget http://wordpress.org/latest.tar.gz
tar -xvzf /root/latest.tar.gz
rsync -avz wordpress/ /var/www/
rm /var/www/index.html
cp /var/www/wp-config-sample.php /var/www/wp-config.php

cd /root

wget http://wordpress.org/latest.tar.gz

tar -xvzf /root/latest.tar.gz

rsync -avz wordpress/ /var/www/

rm /var/www/index.html

cp /var/www/wp-config-sample.php /var/www/wp-config.php

Now set the database credentials in /var/www/wp-config.php:


replace 'database_name_here' 'wordpress' -- /var/www/wp-config.php
replace 'username_here' 'wordpress' -- /var/www/wp-config.php
replace 'password_here' 'YOURNEWPASS' -- /var/www/wp-config.php

replace 'database_name_here' 'wordpress' -- /var/www/wp-config.php

replace 'username_here' 'wordpress' -- /var/www/wp-config.php

replace 'password_here' 'YOURNEWPASS' -- /var/www/wp-config.php

Finally point your web browser to the site and run the WordPress installer.

Canonical Rewrite Rule For Nginx

February 24, 2011

Need to redirect from acme.com to www.acme.com with nginx? No problem … just add a virtual host declaration for the non-www that redirects like this:

server {
  listen 80;
  server_name acme.com;
  rewrite ^/(.*) http://www.acme.com/$1 permanent;
}

server {

listen 80;

server_name acme.com;

rewrite ^/(.*) http://www.acme.com/$1 permanent;

}

or if you want to add to an existing vhost:

if ( $host != 'www.domain.com' ) {
   rewrite ^/(.*)$ http://www.domain.com/$1 permanent;
}

if ( $host != 'www.domain.com' ) {

rewrite ^/(.*)$ http://www.domain.com/$1 permanent;

}
