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.

Turn on PHP register_globals with .htaccess file

February 7, 2010

It is of course a bad idea to write code that depends on register_globals for security reason, but sometimes when faced with old code it’s a necessary evil. You can turn on register_globals for a site or directory by adding the following line to your .htaccess file:

php_flag register_globals on

1 2	php_flag register_globals on

PHP4 and PHP5 On The Same Server

January 22, 2010

If you have a server with PHP4 installed but need PHP5 on some websites then: Install a custom build of PHP5 to /opt/php5. Add lines like the following to your apache virtual host:

AddHandler application/x-httpd-php5 .php 
ScriptAlias /bin /opt/php51/cgi-bin
Action application/x-httpd-php5 /bin/php5

AddHandler application/x-httpd-php5 .php

ScriptAlias /bin /opt/php51/cgi-bin

Action application/x-httpd-php5 /bin/php5

You might also find the RemoveHandler directive handy to disable PHP4.

PHP4 on CentOS5/RHEL5

January 22, 2010

If you need PHP4 on a CentOS5/RHEL5 server then you’ll find the RPMs linked below very handy. They install to /opt/php4 and can coexist with a default PHP 5 install. The included conf.d/php4.conf file includes sample lines to run it as a CGI or as a module. RPMs are here: http://repo.conforge.com/conforge/CentOS/5/i386/RPMS/ http://repo.conforge.com/conforge/CentOS/5/x86_64/RPMS/ See this URL for details to add the yum repo: http://wiki.conforge.com/wiki/Linux-PHP4cgiAndPHP5on+CentOS5
