Re-install Procedure

Here are the steps needed to create a WEB5 class from LUX5 (tested on applogic 2.2.0)

Create an application with only LUX5 and NET in it; configure the NET appliance
Branch LUX5

Resize volumes

```
vol resize LUX5.boot size=300M 
```
```
vol resize LUX5.usr size=500M 
```

Edit the class (in EDT)
1. add a placeholder volume (name: content; mount on /dev/hda3; shared, ro)
2. make the usr volume rw
3. Update terminals: in | In | http db | Out | mysql fs | Out | nfs log| Out | cifs aux| Out | any net| Out | any mon| Out | cce
4. mark net terminal as gateway
5. change the class icon color to blue
6. change the class name to WEB5
7. change the class description
8. change class category to 'Web Servers'
9. Add the following properties:
  - host_name : type = string , dflt = ""
  - admin_email : type = string , dflt = root@localhost
  - content_on_fs : type = string , values = on|off , dflt = off
  - docs_dir : type = string , dflt = ""
  - docs_loc : type = string , dflt = ""
  - scripts_dir : type = string , dflt = ""
  - scripts_loc : type = string , dflt = ""
  - logs_enabled : lowercase , type = string , values = off|on , dflt = off
  - logs_base_dir : type = string , dflt = /
  - access_log_filename : type = string , dflt = ""
  - error_log_filename : type = string , dflt = ""
  - error_log_level : lowercase , type = string , values = debug|info|notice|warn|error|crit|alert|emerg , dflt = warn
  - cgi_ext : type = string , dflt = .cgi
  - shared_perl_ext : type = string , dflt = ""
  - index_files : type = string , dflt = "index.html index.html.var"
  - use_htaccess : lowercase , type = string , values = off|on , dflt = off
  - max_connections : type = integer , min = 1 , max = 256 , dflt = 128
  - persistent_connections : lowercase , type = string , values = off|on , dflt = on
  - idle_timeout_sec : type = integer , dflt = 15
  - data_timeout_sec : type = integer , dflt = 300
  - default_charset : type = string , dflt = off
  - info_level : lowercase , type = string , values = full|os|minor|major|prod , dflt = prod
  - server_signature : lowercase , type = string , values = off|on , dflt = off
  - env : type = string , dflt = ""
10. Set resources
  - CPU: 0.10 | 4 | 0.30
  - MEM: 128M | 8G | 512M
  - BW: 1M |100M | 1M
Connect the net terminal of WEB5 to the net appliance
Create a volume and use it the WEB5 placeholder
Save the application
Start the application in debug mode
Login the WEB5 and do
```
mkdir -p /mnt/content /mnt/log 
```
Install rpms:
```
   yum upgrade
   yum -y install httpd mod_perl ImageMagick ImageMagick-perl mod_ssl mod_auth_mysql sudo
   yum -y install php php-mysql php-gd php-imap php-pgsql php-pear 
   yum -y install perl-TimeDate perl-String-CRC32 perl-MailTools perl-DBD-MySQL
   yum -y install nfs-utils samba-client rsync ntsysv bind-utils sendmail  zip unzip tcpdump telnet words
   
```

rpm -Uv perl-GD-2.35-1.el5.rf.i386.rpm (Current link)
yum clean all
rpm --rebuilddb
Copy the following files in WEB5

Fix init scripts

   chkconfig --levels 12345 sendmail off
   chkconfig --levels 12345 xfs off
   chkconfig --levels 12345 haldaemon off
   chkconfig --levels 12345 avahi-daemon off
   chkconfig --levels 12345 messagebus off
   chkconfig --levels 345 httpd on

Fix log rotation by editing /etc/logrotate.conf and ensuring the following are set:
```
   rotate 4
   size 512k
   
```

Setup permissions of scripts

   chgrp nobody /var/lib/php/session
   cd /appliance ;chown root * ; chmod +x appliance.sh execute_command.sh feed_apache_counters.sh httpd_prerun.sh
   rm  /etc/httpd/conf.d/proxy_ajp.conf

Stop the application

Mount the boot volume of WEB5 (vol mount WEB5.boot) and cleanup.

 
   rm -f root/.bash_history root/.lesshst appliance/log appliance/vmalog appliance/passwd.stamp etc/resolv.conf
   find var/log -type f -exec rm {} \;
   rm -f tmp/*
   echo -n "" > etc/applogic_network.conf
   echo -n "" > etc/hosts
   echo -n "" > etc/applogic/appliance.desc
   echo -n "" > etc/applogic.sh

Umount the boot volume (vol umount WEB5.boot)
Edit class
- add /etc/httpd/conf.d/appl.conf to the configuration files tab (volume: boot; qte method: none)
- make the usr volume ro
Save the application

Vol resize

   vol resize WEB5.boot size=150M
   vol resize WEB5.usr size=330M

Move the class to the /proto catalog or any other catalog of your choosing.
