Install WordPress on Ubuntu virtual server at Media Temple

By admin on May 25, 2011 in Apache, PHP, Ubuntu, WordPress

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

1 2	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.

Remote access via ssh with RedHat Rescue Disk

By admin on July 7, 2009 in RedHat

Insert Rescue Disk and boot server.
At the first prompt type “linux rescue” and hit enter.
Follow boot disk prompts to start networking. Enter the system’s ip address, netmask, gateway and name server.
Continue with prompts until the root partition is mounted and you get a command prompt.
Verify network configuration with ifconfig and route.
Use the following commands to start sshd:

cd /mnt/sysimage chroot /mnt/sysimage mount /dev/pts /sbin/service sshd start

1
2
3
4

cd /mnt/sysimage
chroot /mnt/sysimage
mount /dev/pts
/sbin/service sshd start

You should now be able to SSH into the server.

Mount Windows drive share on RHEL5

By admin on April 24, 2009 in Linux, RedHat

RHEL5 replaced the old smbmount command with mount.cifs so to mount a shared Windows drive do something like:

mount -t cifs //servername/sharename /mnt/mountpoint \
 -o username=myusername,password=mypassword

1 2	mount -t cifs //servername/sharename /mnt/mountpoint \ -o username=myusername,password=mypassword

Reinstall grub in MBR

By admin on April 14, 2009 in RedHat

Two approaches to this. The first is to use the grub-install utility:

grub-install --root-directory=/boot /dev/???

1	grub-install --root-directory=/boot /dev/???

The second approach is to use the grub command line:

1. Start the grub command line:

grub

grub

2. Determine the boot device:

find /boot/grub/stage1

1	find /boot/grub/stage1

You’ll get something like “(hd0,0)”.

3. Tell grub where the root is:

root (hd0,0)

1	root (hd0,0)

4. Install the MBR:

setup (hd0,0)

1	setup (hd0,0)

Fix strange characters from pstree on RedHat.

By default on Redhat, the output from pstree is scrambled like this:

Here are two possible solutions:

1. Use “pstree -G” to force VT100 line drawing

2. Do “export LANG=’en_US'” to change the language from UTF-8 to English
