How To Set Up A Local Yum Repository On Fedora 9

This tutorial shows how to create a Fedora 9 yum repository for your local network. Having a local Fedora mirror is good if you have to install multiple systems in your local network because then all needed packages can be downloaded over the fast LAN connection, thus saving your internet bandwidth.

I do not issue any guarantee that this will work for you!

1. Preliminary Note

In this tutorial I use the hostname server1.example.com with the IP address 192.168.100.10 and port 9090. These settings might differ for you, so you have to replace them where appropriate.

I want to make the yum repository accessible through http; Apache’s default document root on Fedora is /var/www/html, so I’ll create the repository in /var/www/html/yum. If you’re using a different vhost, you might have to adjust the paths.

2. Installing Apache

Let’s install Apache:

yum install httpd

Afterwards, we create the system startup links for Apache (so that Apache starts automatically when the system boots):

chkconfig --levels 235 httpd on

Then we start Apache:

/etc/init.d/httpd start

3. Building The Repository

First we install the tool createrepo:

yum install createrepo

I want to place the Fedora 9 rpm packages for i386 in /var/www/html/yum/base/9/i386 and the update packages in /var/www/html/yum/updates/9/i386, so I create these directories now (adjust the paths if you want to create a repository for Fedora 8/7/… and/or x86_64):

mkdir -p /var/www/html/yum/base/9/i386
mkdir -p /var/www/html/yum/updates/9/i386

Now let’s fill the /var/www/html/yum/base/9/i386 directory. The easiest way is to insert your Fedora 9 DVD (which you can download from here: http://mirrors.fedoraproject.org/mirrorlists/publiclist/Fedora/9), mount it, and copy the rpm packages to /var/www/html/yum/base/9/i386:

mount /dev/cdrom /mnt
cd /mnt/Packages
cp -v * /var/www/html/yum/base/9/i386
cd /
umount /mnt

The DVD contains just a basic set of packages. If you’d like to have all available Fedora 9 packages in the /var/www/html/yum/base/9/i386 directory, you can download the packages (using rsync) from the Everything folder on a Fedora 9 mirror. Go to http://mirrors.fedoraproject.org/mirrorlists/publiclist/Fedora/9, find a mirror that offers rsync, and download the packages as follows (this can take a long time so be patient):

rsync -avrt rsync://ftp-stud.hs-esslingen.de/fedora/linux/releases/9/Everything/i386/os/Packages/ /var/www/html/yum/base/9/i386

(Please make sure you use all slashes as shown above – it must be rsync://ftp-stud.hs-esslingen.de/fedora/linux/releases/9/Everything/i386/os/Packages/, not rsync://ftp-stud.hs-esslingen.de/fedora/linux/releases/9/Everything/i386/os/Packages!)

Afterwards, run the createrepo command:

createrepo /var/www/html/yum/base/9/i386

This will create a repodata directory in the /var/www/html/yum/base/9/i386 directory. Its contents should be as follows:

ls -l /var/www/html/yum/base/9/i386/repodata/

[root@server1 /]# ls -l /var/www/html/yum/base/9/i386/repodata/
total 9268
-rw-r--r-- 1 root root 2227275 2007-12-18 21:11 filelists.xml.gz
-rw-r--r-- 1 root root 6487453 2007-12-18 21:11 other.xml.gz
-rw-r--r-- 1 root root 747714 2007-12-18 21:11 primary.xml.gz
-rw-r--r-- 1 root root 951 2007-12-18 21:11 repomd.xml
[root@server1 /]#

Now let’s fill the updates directory /var/www/html/yum/updates/9/i386. Go to http://mirrors.fedoraproject.org/mirrorlists/publiclist/Fedora/9 again, find a mirror that offers rsync, and download the packages as follows:

rsync -avrt rsync://mirror.internode.on.net/fedora-enchilada/linux/updates/9/i386/ --exclude=debug/ /var/www/html/yum/updates/9/i386

Again, make sure that you use the slashes (/) as shown above!

To make our local mirror download the latest updates automatically from now on, we can create a cron job. For example, to download the latest updates every second day at 04:23h, we create the following cron job:

crontab -e
23 4 */2 * * /usr/bin/rsync -avrt rsync://mirror.internode.on.net/fedora-enchilada/linux/updates/9/i386/ --exclude=debug/ /var/www/html/yum/updates/9/i386

Our local yum mirror is now ready to be used.

4. Client Configuration

To make our Fedora 9 systems use the new local yum repository, we modify /etc/yum.conf on each Fedora 9 system (you can even do this on the mirror itself if it is a Fedora 9 system). Create new file /etc/yum.repos.d/local.repo with these lines:

[base-local]
name=Fedora $releasever - $basearch
failovermethod=priority
baseurl=http://mirror.iwayvietnam.com:9090/yum/base/$releasever/$basearch
enabled=1
gpgcheck=0

[updates-newley-local]
name=Fedora $releasever - $basearch - Updates Newkey
failovermethod=priority
baseurl=http://mirror.iwayvietnam.com:9090/yum/updates/$releasever/$basearch.newkey/
enabled=1
gpgcheck=0

And finally, disable the existing fedora-updates-newkey by this command:

mv /etc/yum.repos.d/fedora-updates-newkey.repo /etc/yum.repos.d/fedora-updates-newkey.repo.bak

Now whenever you use yum and your local repository can serve the requested packages, the packages are downloaded and installed from the local yum repository.

Zimbra Desktop – giải pháp Yahoo Mail, Gmail hoạt động offline

Kết quả của cuộc sáp nhập 350 triệu USD giữa Yahoo và Zimbra là phần mềm e-mail cho phép người dùng đọc nội dung trong hòm thư Yahoo Mail, AOL, Gmail… cả khi máy tính bị ngắt kết nối Internet.

Khi máy tính chưa nối mạng, người sử dụng Yahoo Zimbra Desktop vẫn có thể kéo thả thông điệp vào các thư mục (folder), tạo chữ ký… hay soạn e-mail để lưu vào Outbox và nó sẽ được tự động gửi đi khi hệ thống online trở lại.

“Chúng tôi muốn xóa bỏ khoảng cách giữa ứng dụng web sử dụng tổ hợp công nghệ AJAX và ứng dụng desktop truyền thống”, kỹ sư Mike Morse của Zimbra viết trên blog.

Phần mềm tạo cảm giác như mọi người đang dùng Microsoft Outlook hay Mozilla Thunderbird. Zimbra Mail, Yahoo Mail, Gmail, AOL, Outlook và bất cứ hòm thư cá nhân nào hỗ trợ POP hoặc IMAP đều có thể được cài đặt vào Yahoo Zimbra Desktop để đọc e-mail offline.

Tuy nhiên, Zimbra Desktop tương đối nặng, như dành cho Windows là 48 MB, Mac OS X là 42 MB còn Linux là 52 MB. Tải Yahoo Zimbra Desktop miễn phí tại đây.
