1. You, Your and You’re

You - "You" relates directly to addressing another person. Using "u" in place of "you" when trying to carry on an intelligent conversation is a contradiction in terms. Intelligent people online most often will not take someone as serious when making substitutions like this. If these small details are unimportant to you then receiving correct and/or intelligent feedback or information is equally unimportant and you should re-examine your intent.

Your - "Your" denotes ownership or relation to another person, object or possession. Again, using "ur" in place of "your" or "you're" when trying to carry on an intelligent conversation is a contradiction in terms.

Examples:
"Your shoes are untied."
"I found your wallet."
"Where are your keys?"

You're - "You're" is an abbreviation or contraction of "you" and "are" which is what you'd use when speaking to or about someone in relation to who or what they are. This could entail praise, insult, facts or random statements.

Examples:
"You're very good at that."
"You're the best friend I've got."
"This is something you're going to have to work on."

Recap:
"I can assure you that you're the only one that knows what your favorite ice cream flavor is."

2. There, Their and They’re

There - "There" refers to physical location of a person, object or an event or specific place in time.

Examples:
"Can you meet me over there?"
"There is always a place for you at my table."
"Where there is a will, there is a way."

Their - "Their" refers to ownership of an object, place or relevant place in time.

Examples:
"Their house is very clean and organized."
"Have you got their new telephone number?"
"Their training program is very comprehensive."

They're - "They're" is an abbreviation of "they" and "are" which is what you'd use when speaking to or about someone in relation to who or what they are. This could entail praise, insult, facts or random statements.

Examples:
"They're the best basket weaver in the world!"
"How do you know they're going to answer?"
"In December they're going to meet us."

Recap:
"There was once a place where their ancestors they're always going to have plenty of delicious ice cream."

3. To, Too and Two

To - "To" refers to destination, time or distance.

Examples:
"How can I get from here to there?"
"I went to the store."
"The store is open from 8am to 5pm."

Too - "Too" means "also" or "in addition to" or "in excess of".

Examples:
"This drink is too thick."
"I'd like to be involved too."
"this too is outdated and irrelevant."

Two - "Two" is a number --> 2.

Examples:
"There's no two ways about it."
"Two is the loneliest number that you'll ever know."
"I've got two and that's two too many." 

Recap:
"I'm getting too old to know if two is enough anymore."

Make sure it looks something like this:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       yourhostname localhost.localdomain   localhost
::1             yourhostname localhost6.localdomain6 localhost6
127.0.0.1       wpdev
127.0.0.1       wordpress1
127.0.0.1       wordpress2

2. Create web directories as root:

]# cd /var/www/html; mkdir -p wpdev wordpress1 wordpress2

3. Install httpd, MySQL and PHP and configure them as root:

]# yum install httpd mysql-server php

For instructions on setting up MySQL go Here

6. As root, make sure MySQL and httpd are started and and your web directories are all owned by the user/group your web server runs as (DO NOT DO THIS ON PRODUCTION SERVERS), in our case "apache". Next, browse to your first install:

]# service mysqld restart; service httpd restart

(This step allows you to run 1-click automatic core/theme/plugin updates from within your admin panel without being prompted for a password or ftp credentials) Security tip: DO NOT DO THIS ON PRODUCTION SERVERS
]# chown -Rf apache:apache /var/www/html

Next, open a web browser and go to http://wordpress1

You should be presented with the default WordPress install page.

You can repeat this for as many isolated instances as you want on your laptop or desktop Linux workstation.

chmod +x jre-6u3-linux-i586-rpm.bin; ./jre-6u3-linux-i586-rpm.bin

2. Once the RPM is installed run this command as root and any user on the system should be able to take advantage of Sun Java in Firefox:

ln -s /usr/java/jre1.6.0_03/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/mozilla/plugins/libjavaplugin_oji.sonote: if the directory /usr/lib/firefox/plugins/ does not exist, first create it with thiscommand as root: mkdir /usr/lib/firefox/plugins/
