How to Setup Ubuntu for PPA automation (based on Ubunut 14.04.1)
| Reference | [[Vmplayer]] | [[Office Linux maintenance]] | [[Ubuntu 16.04]] |

====== Update ubuntu via apt-get ======
$ sudo apt-get update 

$ sudo apt-get install update-manager-core

$ sudo do-release-upgrade -d

====== PPA Ubuntu template with basic applications/servers  ======
===== apt-get proxy configure =====
 
configure proxy: /etc/apt/atp.conf
   Acquire::http::proxy "http://proxyconf.xxx.com:81/";
   Acquire::https::proxy "https://proxyconf.xxx.com:81/";
   Acquire::ftp::proxy "ftp://proxyconf.xxx.com:81/";
   Acquire::socks::proxy "socks://proxyconf.xxx.com:81/";
   

then run below command to downloads the package lists from the repositories and "updates" them to get information on the newest versions of packages and their dependencies:

    sudo apt-get update

===== Install vmware tools =====

In vmplayer menu, select player -> Manage -> ReInstall VMWare Tool.

Then it will mount a CDROM under Ubuntu VM. 
{{:mywiki:linux:vmware_tool.png?400|}}

Right on the mounted VMware Tools folder & click on “Extract to” to extract VMware tools files. 

run:
    sudo ./vmware-install.p


Note: 
  * it is very important to install vmware tools, otherwise the vmplayer windows size is fixed and very small.
  * Sometimes downloading vmware tools will fail, in this case, must power down the virtual machine and change CD/DVD to **use physical drive**, like below

===== Disable Network Manager  =====
| Network Manager Configuration File | /etc/NetworkManager/NetworkManager.conf |
| Network interface configuration file | /etc/network/interfaces | any interface not listed there will remain under Network Manager control. |


==== Partial Disable Network Manager  ====
Since any interface not listed in /etc/network/interfaces will remain under Network Manager control, we just move some interface into /etc/network/interfaces to make these interface not under Network Manager control.

For example, below interfaces will not be controlled by Network Manager:
<file>

auto eth1
iface eth1 inet dhcp

auto eth2
iface eth1 inet static

</file>

sudo service network-manager stop

sudo service network-manager start

sudo apt-get remove network-manager

install linux compare tool meld:
   sudo apt-get install meld

Manually download beyond compare via firefox from , for example bcompare-4.0.0.18847_i386.deb

sudo gdebi /xxx/xxx/bcompare-4.0.0.18847_i386.deb


===== apache2 / httpd /TWIKI ===== 
sudo apt-get install apache2

sudo service apache2 restart

Note: In order to execute cgi instead of text display or download, it needs to run:
  sudo a2enmod cgi  
  sudo service apache2 restart

==== Upgrade TWIKI to new version ====  
=== Preparation before install new Twiki ===

  * Mount 2nd virtual machine (data disk only)

    [ ! -d /mnt/data ] && mkdir /mnt/data
    sudo mount /dev/sdb1 /mnt/data/
    
  * create soft link from /mnt/data/www  to /var/www
    cd /var/
    sudo mv www www.old 
    sudo ln -s /mnt/data/www .
    
  * set up twiki configuration in apache2:
    cd /etc/apache2/sites-enabled
    sudo ln -s /mnt/data/general_bin_httpd.conf .
    sudo ln -s /mnt/data/twiki_httpd.conf .

  * restart apache server
    sudo service apache2 restart

=== install new Twiki ===
Install new TWIKI and make it works

  * Download latest TWIKI and extract to /var/www, it will create folder: /var/www/twiki
  * sudo cp /var/www/bin/LocalLib.cfg.txt /var/www/bin/LocalLib.cfg
  * Modify /var/www/bin/LocalLib.cfg file for Variable $twikiLibPath: Must absolutely folder for it
      $twikiLibPath = "/var/www/html/twiki/lib";

  * sudo chown www-data:www-data * -R
  * Run Twiki config for the first time:http://localhost/twiki/bin/configure, setup admin password

and paths.

Edit /var/www/html/twiki/bin/LocalLib.cfg:

     $twikiLibPath = "/var/www/html/twiki/lib";
     
=== Copy old Twiki content to new TWIKI ===
sudo cp /xxx/old_twiki/data/xxx /var/www/twiki/

sudo cp /xxx/old_twiki/data/xxx /var/www/twiki/

sudo cp /xxx/old_twiki/data/.htpasswd /var/www/twiki/.

sudo chown www-data:www-data /var/www/twiki/* -R

Note : Do not forget to enable cgi.load by

sudo a2enmod cgi
sudo service apache2 restart

Enable the conf.d directory created by you for twiki.conf file in apache2.conf file.

==== WebSVN ====  
[[WebSvn|WebSvn Setup]]
====== issues ====== 
===== Issue 1 network not stable =====
  * If there are multiple network interfaces, partially or fully disable network manager seems not work, it always some strange behavior happen: for example, after ubuntu bootup, access ubuntu 14.04 via ssh/ftp will fail/refused, also ping the ubuntu is ok. But if we ping from ubuntu to outside PC, then ssh/ftp access works.
  * Virtunal machine's windows size cannot be expanded, ie, only supported fixed windows size

Fixing: install vmware tools:
   sudo apt-get install open-vm-tools


===== Issue 2 static dns =====
content in /etc/resolv.conf will be auto overwritten. In order to support static DNS, need follow below instruction:

   sudo vim /etc/resolvconf/resolv.conf.d/base

Then put your nameserver list in like so:

  * nameserver 8.8.8.8
  * nameserver 8.8.4.4

Finally update resolvconf:
   sudo resolvconf -u
