How to Install Red Hat Enterprise Linux 5

How to Install Red Hat Enterprise Linux 5

I am going to demonstrate a typical RHEL 5 (Red Hat Enterprise Linux 5) installation in this article. I usually do this kind of installation to host oracle test databases. It should be a good start for you and off course you can customize this process a little bit to suite your environment. I will use a DVD media for RHEL 5.

1. You need to put the DVD in your computer and boot the computer from that DVD.

·  Install Options

2. Next the installer will offer you if you want to check the DVD media before installation. Choose skip here.

·  Disk Check

3. Next you will see the first page of the Installation wizard. Press Next.

·  Welcome Page

4. Select the Language that will be used in the rest of the installation.

·  Installation Language

5. Select the keyboard type.

·  Keyboard Type

6. Next you will be asked to put your installation number. You may skip entering this number if you don't have one.

·  Installation Number

7. Now you need to tell what do you want to do with your disk. I usually choose "Create custom layout" and create the partitions I need on the disk.

·  Hard Drive Partitioning

8. Here is our disk all free space if this is a fresh disk. This is a 30gb disk. Click "New" to create a partition.

·  Create New Partitions

9. First partition will be boot partition size 100m. This will allow the OS to keep the boot record on a separate partition.

·  Create Boot Partition

10. The second partition will be /tmp. The size of /tmp depends upon the oracle database I am going to install e.g. Oracle 10g requires 400mb of space in /tmp and Oracle 11g requires at least 1gb. I will create /tmp with a size of 1.5gb.

·  Create Tmp Partition

11. Then comes the swap partition. The swap's size is dependent on the amount of physical RAM you have. I have 2G of RAM so the swap should be 1.5 times of 2G i.e. 3G. (This formula works for both Oracle 10g and 11g.)

·  Create Swap Partition

12. The fourth partition will be /u01, a partition that will be used specifically for oracle software and database files. I am setting the size to 15gb.

·  Create Partition for Oracle

13. The fifth partition is the "/" which is the root mount point for the operating system. We give it all the space left on the disk.

·  Create root "/" Partition

14. This is how your partitioning scheme should look like when you are done.

·  Review Partitions

15. This screen will ask you if you want to keep the boot record on the disk or not. Keep the defaults and press next.

·  Boot Loader Options

16. Here we will configure the network. Provide a hostname manually. Then click the Edit Button against Network Devices, disable the ipv6 and provide a static IP Address for IPv4. NO DHCP.

·  Network Configuration

17. Click on the map to choose a region for your Time Zone.

·  Time Zone Settings

18. Provide the password for the root (Administrator User in Linux) user.

·  Root Password

19. Select the OS packages that you need. Mostly leaving it as default should be okay. But it is a nice idea to install some development packages which oracle may need while installation. Select "Customize now" and press Next.

·  Install Packages

20. All packages are listed. Right click on the package category and press "Select all optional packages" to install every thing in that category.

·  Custom Packages

21. Press next here, to start the installation.

·  Start Installation

22. This will take several minutes, before the installation is complete. Once the installation is complete the system will reboot. Remove any media from DVD before the system restarts.

·  Installation Progress

23. After rebooting you will have to do some setup tasks. This is the Welcome page of the setup wizard. Press Next.

·  Welcome to Post Installation setup

24. Accept the license agreement and pres Next.

·  License Agreement

25. Disable the firewall and press Next.

·  Firewall Settings

26. Set SELinux "Disabled". If you leave it at "enforcing" you are gonna have trouble with oracle later for example you may not be able to start "sqlplus".

·  SELinux Settings

27. Leave kdump disabled.

·  kdump Settings

28. Set the date and time.

·  Date and Time Settings

29. Select to register at a later time.

·  Product Registration

30. If you have chosen not to register then this page shows that your system is not setup for Updates.

·  Registration Status

31. Use this page to create any additional users other then root.

·  Additional Users

32. Setup your sound card.

·  Sound Settings

33. Use this page to install any additional software. Press Finish when done. The system will reboot again.

·  Additional Softwares

34. After reboot you will see the login screen. Login as root here using the password you provided during the install.

·  Login Screen

35. This is your RHEL 5 desktop. The installation is successful.

·  Desktop

Top 10 Best Firefox Security Add-ons

The main reason most people switch from  Firefox is to improve their browser security, but that doesn't mean Firefox is bullet-proof. We offer up the 10 best add-ons to make everyone's favorite opensource web browser even more secure.

1. Web of Trust (WOT) - You pretty much can't read a Firefox security article without learning about the Web of Trust (WOT) add-on -- and there's good reason. WOT rates every site on the Internet for its security risk: green equals safe, amber equals worrisome and red means avoid like the plague. Simple, easy, and a must-have security measure.

2. AdBlock Plus - The AdBlock Plus Firefox add-on says what it does, does what. AdBlock prevents most advertisements from loading -- especially Flash ads and those layered takeover ads that slow your page loads down -- including all the tracking cookies most ads slip into your system. Even if you aren't paranoid about data-snooping, AdBlock will noticeably speed up your surfing.

3. LastPass - The LastPass Firefox add-on is the granddaddy of password managers. Create one master logon for LastPass itself and it will log you in to every other online service you've got an account with. Moreover, LastPass stops storing your passwords locally in the browser -- where they can be hacked -- and encrypts them into an online account you (and you alone) can access from anywhere. It also has some nice password generation and form auto-completion features, which makes account signups even safer and simpler.

4. BetterPrivacy - The BetterPrivacy Firefox add-on is designed to scrape away the most persistent tracking cookies that websites (and, especially, advertisers) use to profile your online activity. In particular, BetterPrivacy blows away Local Shared Objects (LSOs), the pernicious cookies left behind by Flash applications, videos and websites that most other extensions simply can't erase.

5. NoScript - JavaScript makes a lot of interesting functionality possible on the Web -- including nefarious clickjacking attacks. The NoScript Firefox add-on permits only JavaScript from trusted domains to run in your browser, preventing any unsavory functions from occurring behind the scenes.

6. BugMeNot - It seems every site on Earth wants you to create an account to view their content these days -- mostly so they can track your surfing (even offsite) and sell your data to advertisers (as in spammers). The easiest way to avoid this constraint is the BugMeNot add-on, which provides anonymous credentials for most major sites, allowing you to login without creating or using a "real" account.

7. SpamAvert.com - Where BugMeNot stops, the SpamAvert Firefox add-on picks up. SpamAvert creates quick, disposable e-mail addresses you can use to enroll at sites you don't intend to visit again. The fake e-mail accounts allow you to complete registration, but they also take the hit for follow-up spam, keeping your real accounts clear of the clutter.

8. Beef TACO - The Beef Targeted Advertising Cookie Opt-out (TACO) blocks almost every type of tracking object from settling into your browser. If it's designed to report your web activity to dataminers or advertisers -- including the big dogs like Google, Facebook and Yahoo -- the Beef TACO swats it away. Combine this with BetterPrivacy and you'll be an ad-free phantom in no time.

9. Torbutton - For those that don't know, Tor is a proxy surfing service that prevents even your ISP (or employer) from knowing exactly what web sites you're visiting. The Torbutton Firefox add-on makes using the Tor service dead simple, which is a good thing given how easy it is to turn proxy-configuration a tangle of confusing options. If you want absolutely nobody to know where you've been online, the Torbutton is the place to start.

10. hideBad - Sometimes the biggest security or privacy threat is the one that's right over your shoulder -- literally. The hideBad Firefox add-on offers a browsing panic button that instantly closes every open tab in your browser (while saving the data so you can restore the session later) and replaces them with your homepage. It stops snooping eavesdroppers (and dangerously curious bosses) from knowing which web pages you were just surfing, which may be the most important security measure of them all.

Top 10 Most Popular Torrent Sites of 2013
