Completely Re-install Apache2 on Ubuntu

By -

Find and drop all Apache packages:

1
2
3
4
5
6
7
8
9
10
APACHE_PKGS=`sudo dpkg --get-selections | grep apache | cut -f 1`
# Make sure things are sane:
echo $APACHE_PKGS
# Example output: apache2 apache2-mpm-prefork apache2-utils apache2.2-common \
# libapache2-mod-php5 libapache2-mod-python libapache2-svn
# Likely if you have a Python application:
# libapache2-mod-python libapache2-mod-python-doc libapache2-mod-wsgi
# Or if you roll with the PHP: 
# libapache2-mod-php5
sudo apt-get remove --purge $APACHE_PKGS

Re-install Apache

1
2
3
# You might want to consider not re-installing the whole list;
# instead dump it out, audit, and install what you need:
sudo apt-get install $APACHE_PKGS
After this, all the configuration files were back, and I had a default Apache install.

Start wildfly service with standalone-full.xml

By kris -
Wildfly provides a service.bat in %WILDFLY_HOME%\bin\service. Calling the batch file with the install parameter installs Wildfly as a service on Windows. Once it is installed on windows, you can change the settings so that wildfly starts all the modules and services instead of default minimal setup. For this, change standalone.bat file and add this line : set "SERVER_OPTS=--server-config=standalone-full.xml" This will enable startup of all modules & services of wildfly from now on.

1.First find out how many disks are visible in “fdisk -l” . # fdisk -l 2>/dev/null | egrep '^Disk' | egrep -v 'dm-' | wc -l 2.Find out how many host bus adapter configured in the Linux box.you can use “systool -fc_host -v” to verify available FC in the system. # ls /sys/class/fc_host host0 host1 In this case,you need to scan host0 & host1 HBA. 3.If the system virtual memory is too low ,then do not proceed further.If you have enough free virtual memory,then you can proceed with below command to scan new LUNS. # echo "1" > /sys/class/fc_host/host0/issue_lip # echo "1" > /sys/class/fc_host/host1/issue_lip Note:   You need to monitor the “issue_lip” in /var/log/messages to determine when the scan will complete.This operation is an asynchronous operation. 4.Verify if the new LUN is visible or not by counting the available disks. # fdisk -l 2>/dev/null | egrep '^Disk' | egrep -v 'dm-' | wc -l If any new...
