We were using an older version of Jboss 4.x with JDK 5 on CentOS 5.x, this version of Jboss is very old now, even this version is also not supported by RedHat now.
Now we are upgrading to jboss-eap 6.2 and jdk1.7.0_60 and CentOS 6.x in UAT and AWS Linux1 AMI for Production, I have installed Jboss 6.2 in /var/lib/jboss-eap-6.2 folder. Necessary modification in the code are already done, application is working fine and Jboss is running as a process using below command.
./standalone.sh -c standalone-full.xml -b 0.0.0.0 -bmanagement 0.0.0.0
Below command shows that process is running on port 8080.
netstat -aptn | grep LISTEN
Please help configure Jboss 6.2 as a service and set Auto-start, when OS starts?
Follow the below steps to Configure Jboss6.2 as Service and configure it as Auto restart. The process is same for CentOS 6.x and AWS Linux1 AMI.
Copy files into system directories
a. Copy the modified configuration file to the /etc/jboss-as directory.
mkdir /etc/jboss-as
cp /var/lib/jboss-eap-6.2/bin/init.d/jboss-as.conf /etc/jboss-as/
Uncomment following line
JBOSS_USER=root
and add the following line at the end of this file.
export JBOSS_USER
b. Copy the start-up script to the /etc/init.d directory.
cp /var/lib/jboss-eap-6.2/bin/init.d/jboss-as-standalone.sh /etc/init.d/jboss-62
Do following changes in /etc/init.d/jboss-62 file
i)-Set Java Home JAVA_HOME=/usr/java/jdk1.7.0_60 export JAVA_HOME
ii)-Set JBOSS Home JBOSS_HOME=/var/lib/jboss-eap-6.2 export JBOSS_HOME
iii)-Change Configuration xml file name(you may give what ever configuration file name you are using)
JBOSS_CONFIG=standalone-full.xml
iv)-Add "-b 0.0.0.0 -bmanagement 0.0.0.0" in the following line, so that binding is set for every IP address on this system
daemon --user $JBOSS_USER LAUNCH_JBOSS_IN_BACKGROUND=1
JBOSS_PIDFILE=$JBOSS_PIDFILE $JBOSS_SCRIPT -b 0.0.0.0 -bmanagement
0.0.0.0 -c $JBOSS_CONFIG 2>&1 > $JBOSS_CONSOLE_LOG &
Add the start-up script as a service.
Add the new jboss-as-standalone.sh ( i.e jboss-62 ) service to list of automatically started services, using the chkconfig command.
chkconfig --add jboss-62
Start the service.
service jboss-62 start
Make the service to start automatically when you restart your
server.
chkconfig jboss-62 on
Restart the service
service jboss-62 restart
Now Jboss6.2 configuration as a Service as Auto restart is complete.
Reboot os and check that service is running. Run below command ot verify that service is running on port 8080
netstat -aptn | grep LISTEN | grep 8080

I'm trying to connect to vpnc using a systemd service file. The service file runs a script, myscript.sh, which, among other things, runs:
sudo vpnc myhost
Upon booting the device, the other commands are correctly executed, but the vpn is not connected, and gives me the error message:
vpnc: unknown host `myhost.com'
However, if I run the service file manually using
systemctl start myservice.service
then the vpn is successfully started.
My service file looks like this:
[Unit]
Description=VPN Start
Wants=network-online.target
After=network.target network-online.target
[Service]
Environment=DISPLAY=:0.0
Environment=XAUTHORITY=/home/pi/.Xauthority
Type=forking
ExecStart=/bin/bash /home/pi/myscript.sh
Restart=on-abort
User=pi
Group=pi
[Install]
WantedBy=multi-user.target
systemctl status myservice.service
includes this message:
pi: TTY=unknown ; PWD=/home/pi ; USER=root ; COMMAND=/usr/sbin/vpnc myhost
I have already done:
systemctl enable systemd-networkd-wait-online
and that hasn't appeared to help.
It might be to late, but maybe anyone else stumbles upon this.
I had the same issue although I configured the VPN through the GUI.
I found out eventually that my /etc/resolv.conf was a symlink to a configuration file some third party VPN software I sometimes use installed. Although the entries in that file looked fine it only worked, when I deleted the /etc/resolv.conf symlink and created a new normal file.
TL;DR:
Backup /etc/resolv.conf
Remove symlink
Create new /etc/resolv.conf and populate it with your preferred configuration
After that my VPN worked like a charm.
Unable to start solr server in hybris 5.7 so search is not working . How to start solr server in hybris 5.7 in standalone mode.
In addition to the fine answers above, let me mention all steps, which required to set up the standalone Solr server in SAP Hybris.
Prerequestion
solrserver extension should be there in your localextensions.xml file
Hybris OOTB Solr configuration background
The default configuration is as follows:
solrserver.instances.default.autostart=true
solrserver.instances.default.mode=standalone
solrserver.instances.default.hostname=localhost
solrserver.instances.default.port=8983
solrserver.instances.default.memory=512m
Here, you can see autostart=true which tell Solr server to start and stop together with the Hybris platform.
Setup external Standalone Server
We want to start/stop it independently from Hybris instance. To do so we need disables the autostart for the default Solr instance using below properties.
solrserver.instances.default.autostart=false
solrserver.instances.standalone.autostart=true
solrserver.instances.standalone.mode=standalone
solrserver.instances.standalone.hostname=localhost
solrserver.instances.standalone.port=8983
solrserver.instances.standalone.memory=512m
How to start/stop solr server
You can simply use ant commands to start and stop solr server
ant startSolrServer
ant stopSolrServer
Hybris OOTB, you can find solr setup at hybris/bin/ext-commerce/solrserver/resources/solr/. Now go to bin folder, there you can also run solr script manually as mentioned below.
Start the solr server
./solr start -p 8983 #Linux systems
solr.cmd start -p 8983 #Window system
Stop the solr server
./solr stop -p 8983 #Linux systems
solr.cmd stop -p 8983 #Window system
Find detail post here
In hybris\bin\ext-commerce\solrserver\resources\solr\binrun solr start.
Note that it's the path from version 6. The installation dir might be different, it is the location where the Solr installation bundle has been extracted.
Take a look at the README in solr/server to have the details about the config,log dir etc...
Also take a look at solr -help
Usage: solr COMMAND OPTIONS
where COMMAND is one of: start, stop, restart, healthcheck, create, create_core, create_collection, delete, version, upconfig, downconfig
Standalone server example (start Solr running in the background on port 8984):
solr start -p 8984
SolrCloud example (start Solr running in SolrCloud mode using localhost:2181 to connect to Zookeeper, with 1g max heap size and remote Java debug options enabled):
solr start -c -m 1g -z localhost:2181 -a "-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044"
Pass -help after any COMMAND to see command-specific usage information,
such as: solr start -help or solr stop -help
The solrserver extension provides some additional ant tasks that can be used to control the Solr instances and servers.
Following ant commands can be used
startSolrServer - Starts a Solr server.
stopSolrServer - Stops a Solr server.
We are trying to setup a Single Node Kaa server(version 0.10.0) in an Ubuntu 16.04 machine.
Followed the documentation given here
We were unable to connect to the admin UI after starting the kaa node service.
On investigating further we could see that the Mongodb and zookeeper services were not started. So we manually started those services. After that we were able to connect to Kaa admin UI. Do we need any additional steps to get these service running on kaa-node start ?
I setup kaaproject with the guide for my Ubuntu 16.04.1 LTS VM and Zookeeper was not running by default on my server also, so I had to install the deamon (which starts zookeeper also on startup):
sudo apt-get install zookeeperd
Check if zookeeper is running:
netstat -ntlp | grep 2181
This should result in an output like this:
With mongodb I had the problem, that there was not enough space available for the journal files. I fixed this by increasing the available disk space + setting smallfiles=true in the /etc/mongod.conf
Probably you have some troubles with configurations for services. Check if auto-startup is enabled for MongoDB / Zookeeper by the next command:
$ systemctl is-enabled ${service-name}
if you see this:
$ disabled
then auto-startup is disabled for specified service and you should try next in order to enable it:
$ systemctl enable ${service-name}

I give you the steps extracted from this link chapter "Installing Oracle XE with Docker". It is the simplest way I assure you. Good luck !
1-Install Docker on your Linux machine. You can find instructions for that at http://docs.docker.io/en/latest/installation/ubuntulinux. But it is nothing more then this:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
sudo sh -c "echo deb http://get.docker.io/ubuntu docker main\
> /etc/apt/sources.list.d/docker.list"
sudo apt-get update
sudo apt-get install lxc-docker
2-Pull the image to your machine:
docker pull alexeiled/docker-oracle-xe-11g
3-Run the image:
docker run -d -p 49160:22 -p 49161:1521 -p 49162:8080 alexeiled/docker-oracle-xe-11g
I'm trying to keep SELinux enforcing but to allow NGINX to directly access shared OSX folders that are connected via Parallels Desktop.
Host system: Mac OSX 10.10
Parallels Desktop: 10
Running Virtual OS: CentOS 7 (minimal / command line)
I have the the Parallels tools installed and in CentOS I see the shared folder: /media/psf/Shared-Folder
When I set the Nginx server root to that folder I get a 403 Forbidden. I know it is a configuration parameter that needs editing because if I change SELinux to Permissive, the files are served correctly in NGINX.
When checking how the files are mounted I see this:
root root system_u:object_r:removable_t:s0 /media/psf/Shared-Folder/
I can see the 'removable_t' context - however - my issue is that I cannot seem to find a way to allow the httpd service to serve files that are mounted as removable storage.
I have tried:
chcon -R -t public_content_t /media/psf/Shared_Folder/
chcon -R -t httpd_sys_content_t /media/psf/Development-Projects/
and in all cases I get a "chcon: failed to change context of: '...': Operational not supported" error.
Checking /usr/sbin/getsebool -a | grep http I do not see any option to allow httpd to access removable storage mounts.
Last item: I do not believe I can change the way Parallels mounts the shared folders.
Question: Is there a way to keep SELinux enforcing but to allow NGINX to directly access shared OSX folders that are connected via Parallels Desktop?
What you need to do is use semanage.To get it you have to install policycoreutils-python.
The same type of question has already been asked Here. Cheers!
