Change Static IP to DHCP in CentOS 6

By -

Setting up a Linux for dhcp can be done by editing file using a text editor such as vi:
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
Following is sample static configuration:
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:19:D1:2A:BA:A8
IPADDR=10.10.10.10
NETMASK=255.255.255.0
ONBOOT=yes
Replace static configuration with DHCP:
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:19:D1:2A:BA:A8
ONBOOT=yes
Save and close the file. Just restart network service:

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.
