Note: You can determine which version of those operating systems or CentOS you are using by examining the contents of /etc/redhat-release.

1. Add Google's own YUM repository to be sure you obtain the latest version of the chrome browser, which will allow you to easily ensure you can keep it up-to-date. To do so, create the file /etc/yum.repos.d/google.repo and place the following lines in it depending on whether you are using a 32-bit version of Linux or a 64-bit version. You can check whether you have a 64-bit version by issuing the command uname -a. For a 64-bit version, you will see x86_64 in the output.

   32-bit

   [google]
name=Google - i386
baseurl=http://dl.google.com/linux/rpm/stable/i386
enabled=1
gpgcheck=1
gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub


   64-bit

   [google64] name=Google - x86_64 baseurl=http://dl.google.com/linux/rpm/stable/x86_64 enabled=1 gpgcheck=1 gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub

   Note: you could also put both the 32-bit and 64-bit repo information in the same file, if you wish.

2. Install either the stable, beta, or unstable versions of Chrome from the root account. I would recommend using the stable version.

   ## Install Google Chrome Stable version
yum install google-chrome-stable

## OR install Google Chrome Beta version##
yum install google-chrome-beta

## OR install Google Chrome Unstable version##
yum install google-chrome-unstable

However, if you are using CentOS 5, you won't be able to install the Chrome browser using the above steps. When I attempted to install the package on a CentOS 5.5 system, I saw a message indicating that version 3.2 of the lsb package was needed:

Missing Dependency: lsb >= 3.2 is needed by package google-chrome-stable-6.0.472.53-57914.x86_64 (google64)

The program package-cleanup is found in the yum-utils package.

When I tried updating the lsb package, I saw the following:

Nothing to do

I had similar results when I changed the contents of google.repo to try the 32-bit version, instead.

I found lots of other people reporting the same problem with earlier versions of Red Hat Enterprise Linux (RHEL) 5 and versions of Fedora prior to 12. E.g., there are similar reports at How to install google Chrome in RHEL 5. and Add support for RHEL/CentOS for OS compatibility. At the latter problem report webpage, I found a suggestion from andrewrjones that people wanting to use chrome on CentOS check Chris Staite's webpage, Chrome on CentOS where he provides Chromium for CentOS. Chromium is Google's open source alternative to their Chrome browser.

You can download Chromium for CentOS 5 from his website or from this website. Chromium is an open-source browser project behind the Google Chrome browser that aims to build a safer, faster, and more stable way for all users to experience the web.

Once you've downloaded it, you will need to unzip it and untar it. When you extract the contents of the tar file, a chrome directory will be created beneath the current directory. Make that the working directory and run chrome-wrapper.

# gunzip chrome.tar.gz
# tar -xvf chrome.tar
# cd chrome
# ./chrome-wrapper

You will then be asked to choose the search engine you wish to use from Google, Yahoo!, or Bing.

Once you've started Chromium, you can control and customize it, by clicking on the wrench symbol in the upper, right-hand corner of the Chromium window.

When I ran chrome-wrapper, I received the error message below, but the program ran.

# ./chrome-wrapper
[5578:5592:5060312371904:ERROR:base/nss_util.cc(184)] Error initializing NSS with a persistent database (sql:/root/.pki/nssdb): NSS error code -8174

The program that Chris provides is a 32-bit one.

# file chrome chrome: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), not stripped

I found a discussion of the problems with Chrome and Chromium as well on CentOS systems at Google chrome for CentOS ?? that indicates Google has no interest in supporting Chrome on CentOS 5. There's also helpful information there on the Chromium software available from Chris Staite's site and how to resolve problems encountered with it on CentOS systems, but, since I have a lot of more pressing things to get done, I decided I couldn't afford to spend any more time troubleshooting issues with Chrome and Chromium on CentOS and just deleted the Chromium software from the system on which I had placed it.

I followed the instructions at How to Mount an NTFS Filesystem in order to be able to do so. I issued the command yum install fuse fuse-ntfs-3g dkms dkms-fuse to install the required packages (dkms and dkms-fuse install the fuse kernel module).

The system needs to be configured to use the RPMforge repository in order for the above yum install command to work. See Installing Wine on CentOS or RPMForge Packages and Yum Priorites for information on configuring yum to use the RPMforge repository.

After installing the ntfs-3g driver, I was able to mount the NTFS-formatted drive.

[root@localhost ~]# mkdir /mnt/windrive
[root@localhost ~]# mount -t ntfs-3g /dev/sda1 /mnt/windrive

I first created a mount point, which I arbitrarily named "windrive" under /mnt. Then I needed to specify the file system type with -t ntfs-3g. This particular drive was an external USB drive, which Linux identified as /dev/sda. It had only one partition on it, so I used /dev/sda1 to mount it. If you are unsure how Linux will identify the drive, see Linux Drive Designations

If the NTFS drive contains the Windows operating system for a system and the system was put into hibernation mode when it was shut down, you can only mount it in read-only mode. You will see the following message, which I saw when I tried to mount another drive from a hibernated Windows system, if you don't specify read-only mode for mounting the drive:

# mount -t ntfs-3g /dev/sdc1 /mnt/workdrive
Windows is hibernated, refused to mount.
Failed to mount '/dev/sdc1': Operation not permitted
The NTFS partition is hibernated. Please resume and shutdown Windows
properly, or mount the volume read-only with the 'ro' mount option, or
mount the volume read-write with the 'remove_hiberfile' mount option.
For example type on the command line:

            mount -t ntfs-3g /dev/sdc1 /mnt/workdrive -o remove_hiberfile

I was able to mount the drive by using the -r option for the mount command (you can also use -o ro.

mount -r -t ntfs-3g /dev/sdc1 /mnt/workdrive

The ntfs-3g driver is an open source, GPL licensed, third generation Linux NTFS

Technically it’s based on and a major improvement to the third generation Linux
NTFS driver, ntfsmount. The improvements include functionality, quality and
performance enhancements.

ntfs-3g features are being merged to ntfsmount. In the meanwhile, ntfs-3g is
currently the only free, as in either speech or beer, NTFS driver for Linux
that supports unlimited file creation and deletion.

That placed two new files, mirrors-rpmforge and rpmforge.repo in /etc/yum.repos.d. I then checked to ensure the yum-priorites package was installed.

Summary     : plugin to give priorities to packages from different repos
Description :
This plugin allows repositories to have different priorities.
Packages in a repository with a lower priority can't be overridden by packages
from a repository with a higher priority even if repo has a later version.

I then verified that yum-priorities is enabled by ensuring that the following lines were present in /etc/yum/pluginconf.d/priorities.conf :

[main]
enabled = 1

The yum repository information is stored in /etc/yum.repos.d.

[root@localhost ~]# ls -l /etc/yum.repos.d
total 32
-rw-r--r-- 1 root root 2049 Jun 19 09:48 CentOS-Base.repo
-rw-r--r-- 1 root root  626 Jun 19 09:48 CentOS-Media.repo
-rw-r--r-- 1 root root  684 Mar  8  2007 mirrors-rpmforge
-rw-r--r-- 1 root root  428 Mar  8  2007 rpmforge.repo

I added priority=1 as the last line in the following sections of CentOS-Base.repo:

[base]
[updates]
[extras]

I added priority=2 as the last line in the [centosplus] .

I edited /etc/yum.repos.d/rpmforge.repo and added priority = 11 at the end of the file.

Repositories with lower priority numbers are considered to have a higher priority than than those with higher numbers. E.g. if repository A has priority=4 associated with it while repository B has priority=5 associated with it, repository A has a higher priority than repository B.

After adding the RPMForge repository, I was then able to install Wine with yum install wine. The following dependencies were also instaled:

After the installation, I ran winecfg.

[root@localhost ~]# winecfg
wine: created the configuration directory '/root/.wine'
Could not load Mozilla. HTML rendering will be disabled.
wine: configuration in '/root/.wine' has been updated.

Wine was configured to emulate Windows XP by default. I clicked on the Desktop Integration tab and set the "My Documents", "My Pictures", "My Music", and "My Videos" folders to link to directories I created under a "Documents" folder, I created under the login directory for the account I was logged in under. The directories must be created before you link to them with the Wine configuration utility.

[root@localhost Documents]# mkdir Pictures
[root@localhost Documents]# mkdir Music
[root@localhost Documents]# mkdir Videos

In the Wine configuration window, I clicked OK to retain the default settings. When I was returned to the shell prompt, I ran wine notepad to test Wine with the notepad application.

First, install the yum-priorities package with yum install yum-priorities. This plugin allows repositories to have different priorities. Packages in a repository with a lower priority can't be overridden by packages from a repository with a higher priority even if the repository with the higher priority has a later version of the package. As the Installing RPMForge webpage states you should "Beware that some packages are newer than the official CentOS version and you should not blindly install those packages. Before you replace a CentOS package you should make sure that will not break anything important. In most cases you can revert any mistakes but it is best to avoid the mess." By usng the yum-priorities plugin, you help avoid that problem.

Next verify that yum-priorities is enabled by ensuring that the following lines are present in /etc/yum/pluginconf.d/priorities.conf :

[main]
enabled = 1

The yum repository information is stored in /etc/yum.repos.d.

cd /etc/yum.repos.d
# ls -l
total 16
-rw-r--r-- 1 root root 2049 Nov 22 20:32 CentOS-Base.repo
-rw-r--r-- 1 root root  622 Nov 22 20:32 CentOS-Media.repo

I added priority=1 as the last line in the following sections of CentOS-Base.repo:

[base]
[updates]
[extras]

I added priority=2 as the last line in the [centosplus] section, which now contains the following lines:

[centosplus]
name=CentOS-$releasever - Plus
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus
#baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
priority=2

I installed the rpmforge-release package with rpm -Uhv rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm, which created two new files mirrors-rpmforge and rpmforge.repo in /etc/yum.repos.d. I edited rpmforge.repo and added priority = 11 at the end of the file.

Repositories with lower priority numbers are considered to have a higher priority than than those with higher numbers. E.g. if repository A has priority=4 associated with it while repository B has priority=5 associated with it, repository A has a higher priority than repository B.

The city manager, Jerry Taylor, who claims to have twenty-two years in computer systems engineering and operations, but appears to know very little about webservers or operating systems, saw the default Apache webpage one would see on a webserver running the CentOS operating system and contacted a CentOS developer, Johnny Hughes. But, with absolutely no understanding of what he was seeing, he demanded that the CentOS software be removed from his website.

In one email message sent to CenOS he railed "Who gave you permission to invade my website and block me and anyone else from accessing it??? Please remove your software immediately before I report it to government officials!! I am the City Manager of Tuttle, Oklahoma." Mr Hughes tried to explain the situation to him, but Mr. Taylor was apparently incapable of understanding the explanations and replied by threatening to sic the FBI on CentOS. Mr. Hughes took the time to research the problem instead of just ignoring the city manager at that point and did eventually get the city manager to contact his hosting provider. But even then, the city manager did not seem to understand, or at least appreciate, that Mr. Hughes had made an extra effort to solve the city's website problem for the city. Instead he still stated he did not regret threatening Hughes with FBI action, since he believes that was what prompted Hughes to start treating him seriously.

The city has a article on the issue at City manager misunderstanding prompts international response and even has a link to the email transcript of the exchange, which Mr. Hughes posted after getting exasperated with the city manager's behavior and threats. Comments on the article in the city's paper are available in a forum for the paper.
