Tips For SSD Installation

Aug 30, 2015
Technology

Refers to:
https://wiki.archlinux.org/index.php/Beginners’guide%28%E7%AE%80%E4%BD%93%E4%B8%AD%E6%96%87%29

Partition

Check if you are in efi mode:

# efivar -l

Then format your disk using parted:

# parted /dev/sda
(parted) mkpart ESP fat32 1M 513M
(parted) set 1 boot on
(parted) mkpart primary ext4 513M 100%

Check if your partition is aligned:

# blockdev --getalignoff /dev/sda
0

I have 2 disks, one for ssd, the other for hdd, so I want to share the swap partition, and locate the /var directory in the hdd, modify it via:

# mkfs.ext4 /dev/sda2
# mkfs.vfat -F32 /dev/sda1
# mount /dev/sda2 /mnt
# mkdir -p /mnt/boot
# mount /dev/sda1 /mnt/boot
# swapon /dev/sdb1
# mkdir /media/
# mount /dev/sdb2 /media
# mkdir /media/var_for_sda
# ln -s /media/var_for_sda /mnt/var

Now you could do pacstrap.

Installation

Installation are the same as the guildeline show,

# pacman -S dosfstools efibootmgr
# bootctl --path=/boot install
# vim /boot/loader/entries/arch.conf
title          Arch Linux
linux          /vmlinuz-linux
initrd         /initramfs-linux.img
options        root=/dev/sda2 rw
# vim /boot//loader/loader.conf
#timeout 3
default arch
timeout 5

For wireless connection:

# pacman -S iw wpa_supplicant
# pacman -S dialog

Modification of the /etc/fstab:

# /dev/sda2
UUID=xxxxxxxxxxxxxxxxxxxxxxxx       /               ext4 default,rw,data=ordered,noatime,discard 0 1

# /dev/sda1
UUID=xxxxxxxxxxxxxxxxx          /boot           vfat rw,noatime,discard,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro  0 2

# /dev/sdb1
UUID=xxxxxxxxxxxxxxxxxxx       none            swap defaults        0 0

# /dev/sdb2
UUID=xxxxxxxxxxxxxxxxxxx       /media          ext4	 rw,relatime,data=ordered        0 2

# Only for /var , use mount -o bind
/media/var_for_sda      /var    none    bind

Now reboot everything will be OK.

Configuration For SSD

Profile-sync-daemon for optimization of Browser :

$ yaourt profile-sync-daemon
$ sudo vim /etc/psd.conf
USERS="XXXXX"
BROWSERS="chromium firefox"
USE_OVERLAYFS="yes"
$ sudo systemctl enable psd.service
$ sudo systemctl start psd.service

Test it via:

$ profile-sync-daemon parse

Use firefox -P for changing the profile position. I put all of the profils on HDD.

For chromium, softlink the ~/.config/chromium to HDD disk then you play the tricks for avoiding HDD from too much write. .

Quickly Add User

Use following command for quickly adding the user with specified priviledge:

# useradd -m -g root -G \
audio,video,floppy,network,rfkill,scanner,storage,optical,power,wheel,uucp -s  \
/usr/bin/zsh xxxxx
# passwd xxxxx

GPT/SSD on ArchLinux Installation

Aug 30, 2015
Technology

Since I met so many problems in archlinux installation on SSD, plus UEFI issues, I use following virt machine for re-produce the problem and try to find out the solution.

Prepare

Prepare two disk, one for SSD, the second is the oridinary one.

$ qemu-img create -f qcow2 -o cluster_size=4k ArchSSD.qcow2 100G
$ qemu-img create -f qcow2 ArchHDD.qcow2 80G
$ virt-manage

UEFI Support In Virt-Manager

Follow the tips in https://fedoraproject.org/wiki/Using_UEFI_with_QEMU

# wget http://www.kraxel.org/repos/firmware.repo -O /etc/yum.repos.d/firmware.repo
# yum install edk2.git-ovmf-x64
# vim /etc/libvirt/qemu.conf
 nvram = [
    "/usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd:/usr/share/edk2.git/ovmf-x64/OVMF_VARS-pure-efi.fd",
 ]

In customization of the vm, select like following:

/images/2015_08_30_10_09_31_306x202.jpg

Virtual Machine Definition

The configuration of the vm machine is listed as in following picture:

/images/2015_08_30_09_28_46_445x204.jpg

So now begin to install virt-machine. Use iso for booting up the machine and you will see following partition configuration in the terminal:

root@archiso ~ # fdisk -l /dev/vda
Disk /dev/vda: 100 GiB, 107374182400 bytes, 209715200 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
root@archiso ~ # fdisk -l /dev/vdb
Disk /dev/vdb: 80 GiB, 85899345920 bytes, 167772160 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Partition Preparation

Use Jenkins For Building Packer Images

Technology

Installation Jenkins

Refers to https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu

$ wget -q -O - https://jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -
$ sudo sh -c 'echo deb http://pkg.jenkins-ci.org/debian binary/ > /etc/apt/sources.list.d/jenkins.list'
$ sudo apt-get update
$ sudo apt-get install -y jenkins

Install Packer Plugins

Manually(But failed), so finally I use the web-backed for installing.

$ wget https://ci.jenkins-ci.org/jnlpJars/jenkins-cli.jar
$ java -jar jenkins-cli.jar -s http://localhost:8080 help
$ java -jar jenkins-cli.jar -s http://localhost:8080 list-plugins
$ java -jar jenkins-cli.jar -s http://localhost:8080 install-plugin \ 
http://ftp.yz.yamagata-u.ac.jp/pub/misc/jenkins/plugins/packer/1.2/packer.hpi

/images/2015_08_26_16_56_22_672x344.jpg

After installation, restart service via service restart jenkins.

How to use it? later will investigate.

Enable Trusty KickStart For SpaceWalk

Aug 25, 2015
Technology

Import distro-tree

Copy iso content into the distro-tree:

# mount -t  iso9660 -o loop /mnt/iso/ubuntu-14.04.3-server-amd64.iso /mnt1/
# mkdir /var/distro-trees/ubuntu-14.04.3-amd64
# chmod 755 /var/distro-trees/ubuntu-14.04.3-amd64/
# cp -ar /mnt1/* /var/distro-trees/ubuntu-14.04.3-amd64/

We will copy the pxeboot startup file from CentOS7 into ubuntu14.04 distro tree for cheating the spacewalk:

# mount -t iso9660 -o loop /mnt/iso/CentOS-7-x86_64-Everything-1503-01.iso /mnt2/
# mkdir -p /var/distro-trees/ubuntu-14.04.3-amd64/images/pxeboot/
# cp /mnt2/images/pxeboot/{initrd.img,vmlinuz} /var/distro-trees/ubuntu-14.04.3-amd64/images/pxeboot/
# ls /var/distro-trees/ubuntu-14.04.3-amd64/images/pxeboot/ -l -h
....

Kickstarting

Now in spacewalk go to Systems->Kickstart->Distributions, with the parameters like following picture:

/images/2015_08_25_16_17_53_595x352.jpg
We copy the CentOS Kernel and initrd, so Spacewalk use redhat parameters for this distribution, later we will fix this.

Now create a profile via go to Systems->Kickstart->Profiles and “upload a new kickstart file”, just like following picture.

/images/2015_08_25_16_22_53_617x590.jpg

We fix the hardcoded breed from redhat to ubuntu via following steps:

Get the list info via cobbler list:

/images/2015_08_25_16_27_12_515x205.jpg

Report the selected distro info:

# cobbler distro report --name=trustyamd64:1:SpacewalkDefaultOrganization

/images/2015_08_25_16_28_48_990x256.jpg

Edit it like following:

# cobbler distro edit --name trustyamd64:1:SpacewalkDefaultOrganization --breed=ubuntu --os-version=jaunty --initrd=/var/distro-trees/ubuntu-14.04.3-amd64/install/netboot/ubuntu-installer/amd64/initrd.gz --kernel=/var/distro-trees/ubuntu-14.04.3-amd64/install/vmlinuz

We should notice the initrd file and kernel has been modified!!!

/images/2015_08_25_16_32_24_933x261.jpg

Now edit the /var/lib/tftpboot/pxelinux.cfg/default file, find the item and modify it like following:

LABEL trustykickstart:1:SpacewalkDefaultOrganization
        kernel /images/trustyamd64:1:SpacewalkDefaultOrganization/vmlinuz
        MENU LABEL trustykickstart:1:SpacewalkDefaultOrganization
        append initrd=/images/trustyamd64:1:SpacewalkDefaultOrganization/initrd.gz  ks=http://192.168.0.79/trustykickstart.cfg ksdevice=eth0 --
        ipappend 2

Now you could kickstart your ubuntu trusty now.

Register to SpaceWalk

First create a key under spacewalk for activating all of the trusty clients:
/images/2015_08_26_11_10_35_378x489.jpg

Register the client via:

# apt-get install apt-transport-spacewalk rhnsd
# vim /usr/lib/python2.7/xmlrpclib.py
    def dump_nil (self, value, write):
    - if not self.allow_none:
    - raise TypeError, "cannot marshal None unless allow_none is enabled"
    +# if not self.allow_none:
    +# raise TypeError, "cannot marshal None unless allow_none is enabled"
# apt-get install python-libxml2
# mkdir /var/lock/subsys
# vim /etc/hosts
10.11.11.3      spacewalk
# rhnreg_ks --activationkey=1-trustyamd64 --serverUrl=http://spacewalk/XMLRPC
Warning: unable to enable rhnsd with chkconfig

Register to the main channel:

# cat /etc/apt/sources.list.d/spacewalk.list
deb spacewalk://spacewalk channels: main
# apt-get update

Added more software channels in the spacewalk web.

/images/2015_08_26_11_22_13_607x454.jpg

Met many problems, perhaps the repository error.

Fix Bug, In spacewalk server, change following items:

[root@spacewalk trusty-ia32]# cat Packages | grep -i "Package: python$" -A2
Package: python
Version: 2.7.5-5ubuntu3
Multi-Arch: allowed
[root@spacewalk trusty-ia32]# cat Packages | grep -i "Package: python3$" -A2
Package: python3
Version: 3.4.0-0ubuntu2
Multi-Arch: allowed
[root@spacewalk trusty-ia32]# pwd
/var/cache/rhn/repodata/trusty-ia32

And regenerate the Packages.gz via:

# rm -f Packages.gz
# gzip -c Packages Packages.gz

Now re-install firefox you won’t meet problem.

Enable “Push”

Install the packages, precise’s package will also be OK for trusty.

Notice, the Trusty could use saucy based deb.

$ wget https://launchpad.net/~mj-casalogic/+archive/ubuntu/spacewalk-ubuntu/+files/rhncfg_5.10.14-1ubuntu1%7Esaucy2_all.deb
$ wget https://launchpad.net/~mj-casalogic/+archive/ubuntu/spacewalk-ubuntu/+files/osad_5.11.27-1ubuntu1%7Esaucy5_all.deb
$ wget https://launchpad.net/~mj-casalogic/+archive/ubuntu/spacewalk-ubuntu/+files/pyjabber_0.5.0-1.4ubuntu3%7Esaucy1_all.deb
$ sudo dpkg -i osad_5.11.27-1ubuntu1~saucy5_all.deb
$ sudo dpkg -i pyjabber_0.5.0-1.4ubuntu3~saucy1_all.deb

Import the certification file and modify the osad’s certification file:

# cd /usr/share/rhn
# wget http://spacewalk.example.com/pub/RHN-ORG-TRUSTED-SSL-CERT
# vim /etc/sysconfig/rhn/up2date
sslCACert=/usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT
# vim /etc/sysconfig/rhn/osad.conf
osa_ssl_cert = /usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT
# service osad start
# update-rc.d osad defaults
# reboot

If you encounter problem, check the version of the osad/pyjabber, remove the precise version and install saucy version on Trusty via dpkg -P osad && dpkg -P pyjabber, install the right version, then everything will becomes OK.

Enable Remote Command

Install and Configure it via:

# dpkg -i rhncfg_5.10.14-1ubuntu1~saucy2_all.deb 
# rhn-actions-control --enable-run
# mkdir /var/spool/rhn

Also add configuration:
/images/2015_08_27_15_09_31_375x346.jpg

Now you could run command in spacewalk backend.

Errata

Following the tips on http://cefs.steve-meier.de/
Import erratas into the system.

# ./errata-import.pl --server spacewalk --errata ./errata.latest.xml  --rhsa-oval \
./com.redhat.rhsa-all.xml --channel centos6-i386 --os-version 6 --publish

Add CentOS Client into SpaceWalk

Aug 25, 2015
Technology

Installation

Take i386 architecture for example, first download the rpm package then install it:

$ wget /yum.spacewalkproject.org/2.3-client/RHEL/6/i386/spacewalk-client-repo-2.3-2.el6.noarch.rpm
$ rpm -ivh spacewalk-client-repo-2.3-2.el6.noarch.rpm

If your architecture is x86_64, then select x86_64 corresponding rpm and install it.

Enable EPEL:

# BASEARCH=$(uname -i)
# rpm -Uvh http://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm

Now install the spacewalk client via:

# yum install -y rhn-client-tools rhn-check rhn-setup rhnsd m2crypto yum-rhn-plugin

Configuration

Install Spacewalk server’s CA certificate on the server to enable SSL communication:

# wget http://10.11.11.3/pub/rhn-org-trusted-ssl-cert-1.0-1.noarch.rpm
# rpm -ivh rhn-org-trusted-ssl-cert-1.0-1.noarch.rpm

Add following item into the /etc/hosts and test its reachable:

# vim /etc/hosts
....
10.11.11.3      spacewalk
# ping spacewalk
PING spacewalk (10.11.11.3) 56(84) bytes of data.
64 bytes from spacewalk (10.11.11.3): icmp_seq=1 ttl=64 time=0.214 ms
...

Now register your machine into the server:

#  rhnreg_ks --serverUrl=https://spacewalk/XMLRPC --sslCACert=/usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT --activationkey=1-centos6-i386

Verify it in SpaceWalk’s system details view.

Enable osad

Install and configure it via:

# yum install osad
# vim /etc/sysconfig/rhn/osad.conf
osa_ssl_cert = /usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT
# yum install python-hashlib
# service osad start

After osad has been installed, the installation of packages will be done almost instantly.
