Testing the installation of Archlinux: Manjaro XFCE 8.7.1

Creating Manjaro Live Installation Media

    diskutil list
    diskutil unmountDisk /dev/disk2 //flash is connected to disk2
    dd of=/dev/disk2 if=/path/to/manjaro-xfce-0.8.7.1-x86_64.iso
    diskutil eject /dev/disk2

Installing Manjaro XFCE 8.7.1 via Installation Wizard

  • Boot from the USB Drive.
  • When prompted type in ‘stat’ press enter to select Manjaro Live.
  • Click on the Manjaro installation manager icon on the Desktop and walk through the installation process.
  • When prompted for a username, choose one that is NOT your SOE login! For example "elnaz_local" rather than my SOE login of "elnaz". Otherwise you will not be able to login to your computer after you setup LDAP.
  • When prompted for a machine name, enter the name that machine is supposed to be (mascd11, omelette, quiche, etc)
  • Selecting 'Edit Partitioning' will launch gparted which will allow you to delete current partitions and/or add new partitions.
    • At least 3 partitions are needed.
      • ~2G storage for /boot and select ‘ext2’ as the format.
      • At least 8-10G for swap and select ‘linux-swap’ as the format.
      • The rest of the storage space can be partitioned as root ‘/‘ with the ‘ext4’ format.
      • You can add other partition such as home directory.
      • Click on 'Edit' and select 'Apply All Partitions' to save the changes. And quit the program.
  • Right click on ~2G partition and mount it as /boot. The format should be 'ext2'.
  • Right click on the largest partition (i.e. root) and mount is as '/'. Click Forward.
  • Leave grub to be installed in the default partition.
  • Deselect Plymouth login manager. You should install a different login manager later, for instance SLiM.
  • Review the summary of the changes you have made. And click on 'install'.
  • Installation wizard should complete as normal.

NOTE: when partitioning the disk, make sure root and boot partitions are on one disk. Otherwise, you will not be able to boot from hard drive.

Account Setup

Enable root account. Open a terminal window. And enter your new root password for the machine 

 sudo su -   
 passwd

Add your local and SOE logins to the list of sudoers: 

vi /etc/sudoers

Package Installation

Update all the installed packages on your system. 

pacman -Syu

Expand this section to view the list of packages that need to be installed. Please install in order of appearance.

[Expand] 
List of Packages

You might need to reboot your system afterwards but please update the packages again before rebooting or you may not be able to boot! 

pacman -Syu

Firewall Setup

Setup the firewall: 

ufw default deny
ufw reject auth
ufw limit ssh/tcp
ufw logging off

The next line is only needed the first time you install the package. 

ufw enable

Follow it by enabling ufw with systemctl. 

systemctl enable ufw.service

Finally, query the rules being applied via the status command. 

ufw status

NVIDIA Driver Installation

By default, video-nvidia-nouveau is installed. Remove it and install video-nvidia instead.

The following command will list the basic information of all the drivers currently installed on your system. 

mhwd -li -d

Filter the drivers used on a hardware with a PCI connection: 

mhwd -li -d --pci

To remove the installed driver for nvidia graphics card use the following command. 

mhwd -r pci video-nvidia-nouveau

You will also need to manually remove nouveau from the conf file. Edit /etc/mkinitcpio.conf by commenting out the following line. 

MODULES=" nouveau"

And install video-nvidia driver 

mhwd -i pci video-nvidia

MADA Related Installations

autofs

Install autofs. 

pacman -S autofs
Create a mada directory.
 mkdir /mada

Configure. 

scp <username>@mascd5.cse.ucsc.edu:/etc/autofs/auto.mada      /etc/autofs/
scp <username>@mascd5.cse.ucsc.edu:/etc/autofs/auto.master   /etc/autofs/

When you are done configuring, launch the AutoFS daemon as root: 

systemctl start autofs

To start the daemon on boot: 

systemctl enable autofs

Edit /etc/autofs/auto.mada 

users               -rw,intr,soft,noquota,noatime,fstype=nfs4 mada0.cse.ucsc.edu:/mada/users 
software            -ro,intr,soft,noquota,noatime,fstype=nfs4 mada0.cse.ucsc.edu:/mada/software

Then createthe link: 

ln -s /mada/users /soe

Reload autofs 

systemctl reload autofs

Now you should be able to see both /mada/users and /mada/software in your /mada directory. If you do not see those folders mounted. autofs was not setup properly. Reconfigure.

SSH

Enable ssh service 

systemctl restart sshd.service
systemctl enable sshd.service

To enable X forwarding. 

vi /etc/ssh/sshd_config

Make sure X11 forwarding option is set to yes 

X11Forwarding yes

Now you should be able to ssh to your machine using the local username you have created. 

ssh x_local@masdx.cse.ucsc.edu

LDAP

Please do not reboot while setting up LDAP until you make sure it works! Otherwise you might end up locking yourself out and having to re-install!

Install the following packages. 

pacman -S openldap nss nss_ldap pam_ldap cyrus-sasl-ldap lib32-libldap
yaourt  -A nss_updatedb //Type N to edit build package and Y for installation

You have already set your host name as mascdx. Check: 

vi /etc/hostname

If it is not set, set it using the following command. 

hostnamectl set-hostname mascdx

Now mascdx is in /etc/hostname

Disable Modem Manager. 

systemctl disable ModemManager

To get a list of current NIC names use: 

ls /sys/class/net

Output example: 

eno1  lo

You can use either dhcpcd or NetworkManager to configure the network. Do not leave both 'active'. 

systemctl stop NetworkManager.service
systemctl disable NetworkManager.service
systemctl enable dhcpcd.service
systemctl start dhcpcd.service

Copy LDAP configuration files: 

scp <username>@mascd6.cse.ucsc.edu:/etc/openldap/ldap.conf /etc/openldap/ldap.conf
scp <username>@mascd6.cse.ucsc.edu:/etc/nss_ldap.conf /etc/nss_ldap.conf
scp <username>@mascd6.cse.ucsc.edu:/etc/pam_ldap.conf /etc/pam_ldap.conf
scp <username>@mascd6.cse.ucsc.edu:/etc/pam.d/system-auth /etc/pam.d/system-auth
scp <username>@mascd6.cse.ucsc.edu:/etc/pam.d/su-l /etc/pam.d/su-l
scp <username>@mascd6.cse.ucsc.edu:/etc/pam.d/mdm /etc/pam.d/mdm
scp <username>@mascd6.cse.ucsc.edu:/etc/pam.d/sudo /etc/pam.d/sudo

Copy nss switch configuration file. 

scp <username>@mascd6.cse.ucsc.edu:/etc/nsswitch.conf  /etc/.

Now you should be able to execute the following command. 

ldapsearch -x LLL

Copy imapd configuration file. 

scp <username>@mascd5.cse.ucsc.edu:/etc/idmapd.conf  /etc/.

Restrict access to your machine by copying and editing /etc/security/access.conf. 

scp <username>@mascd5.cse.ucsc.edu:/etc/security/access.conf  /etc/security/.

You will need to add your local login to the machine, or you will lock yourself out. 

vi /etc/security/access.conf

Go to very bottom of file and add your local user account to the list below root. Example of the last lines of my file (Replace "elnaz_local" with your local login). 

+ : root : ALL 
+ : elnaz_local : ALL 
+ : nx : ALL 
+ : gitosis : ALL 
+ : (masc) : ALL 
+ : (vlsi) : ALL 
+ : (mada0) : ALL 
- : ALL : ALL

Calling "su - other_username" should say "permission denied", but, calling "su - your_user_name" should work.

Then edit /etc/conf.d/nfs-common.conf, find NEED_IDMAPD and set it to: 

NEED_IDMAPD="yes"

Finally, the default gnome desktop manager on Manjaro is too buggy. We recommend that you use xfce instead. for this edit ".dmrc" in your home directory and set it to the following: 

[Desktop]
Session=xfce

You should be able to ssh into your own machine again. Once you have verified that LDAP is working, you may then reboot.

To get other users to have access to their home directories on your machine, you should run the following: 

sudo ln -s /mada/users /soe

Synopsys Tools Required Libraries

Having installed xorg-server xorg-server-common, I still had to install the following. 

pacman -S xorg-server-devel

Install more and more fonts. Some of them are required by the Synopsys tools. 

pacman -S $(pacman -Ssq font)
pacman -S $(pacman -Ssq ttf)

Install libtermcap which needed by Synopsys simulator. 

#Download termcap-2.0.8.tar.gz
wget masc.soe.ucsc.edu/termap-2.0.8.tar.gz
cd termcap-2.0.8

# Build and install
sudo make install

# set link library paths
sudo cp termcap.conf /etc/ld.so.conf.d/
sudo ldconfig

Ruby Related Stuff

We use RVM to support multiple ruby versions. Install the base versions shared by all the users : 

sudo pacman -S curl
\curl -L https://get.rvm.io | bash -s stable --ruby

Log in with user foo and add yourself (foo) to to the rvm group (vi /etc/group). Then install the following ruby options: 

rvm install ruby-1.8.7
rvm install rbx
rvm install rbx-2.0.0-rc1 # This may be better in the future, but rbx 2 has several advantages
rvm install ruby-1.9.3
rvm install jruby

Now log in as user foo and you should be able to change using ruby version: 

rvm use 1.9.3

You may need to tun the following command to allow login shell and then change the using ruby version: 

/bin/bash --login

Install the following packages: 

gem install rspec parslet treetop trollop rgl json gherkin cucumber rsec

Update All Packages
