Cannot Start Elastic Search on Ubuntu 17 - linux

I installed the Elastic Search by downloading the .deb package from this link.
After installing I tried to browse to http://localhost:9200/ where I'm getting connection refused error, so I checked the status of elastic search service by running the following command sudo service elasticsearch status and I'm getting the below logs :

Can some one tell me how to start the service?

kindly check the source list, in your source list might be something that disables the SSH
kindly use the different source list
Kindly change your /etc/apt/source.list to this Link it might work.

Apache on my rPi LAMP box stopped working for no reason

I was editing /etc/crontab when things turned south. I have no idea why, and I rolled back my changes on the /etc/crontab file but apache is still messed up and I can't access local development websites hosted on this machine. When I run systemctl status apache2.service this is what I get:

Any ideas? I can't seem to trace what's wrong here.

Unable to start Logstash service on Centos7

When i am trying to start the logstash as a service in centos 7 i am getting below error all the time. I am not a great linux guy, so any help with the start-limit error would be a great help. I tried to follow some links to fix or reset the StartLimitInterval etc, but in vain.

I met the same problem, and solved it. Maybe it can help you.
Can you check your ${LS_HOME}/config/startup.options file? You should set LC_USER and LC_GROUP to existed account and group .
# user and group id to be invoked as
LS_USER=elk-test
LS_GROUP=elk-test
In my system, I changed the default value "logstash" to "elk-etst".
After that, ran the system-install command, and started the service, it worked!

Why systemctl services are loaded but failed CentOS 7

I finished to install Openstack Magnum service on CentOS 7, using this guide: http://docs.openstack.org/developer/magnum/install-guide-from-source.html
Checking the magnum-api and magnum-conductor services after reboot shows that the services are active, but few seconds later they are in failed state. The selinux is disabled, and the services are enabled.
Restarting the magnum api service:
[root#controller01 magnum]# systemctl restart magnum-api
magnum-api status OK:
[root#controller01 magnum]# systemctl status magnum-api

Happens the same for the magnum-conductor service.
How can I fix this?
Thanks,
Dedi
Thanks #Petesh. I just figure it out. The issue was because I set in the magnum.conf file:
host = controller.
Once I replaced the "controller" with the ip, it works. In other words, set:
host = <controller_IP>.
