如何在Centos 6.5中自动启动elasticsearch？

Question

I have installed elasticsearh on a server based on Cent OS 6.5. To start it:

# cd /usr/share/elasticsearch/elasticsearch-1.5.2]
# ./bin/elasticsearch &

But when I close the terminal, the process is killed. How can I set it to automatically start as a service?

Answer 1

Try using the "nohup" command with elastic search.

$ nohup ./bin/elasticsearch

Now what the nohup does? In the following example, it starts the program abcd in the background in such a way that the subsequent logout does not stop it.

$ nohup abcd &
$ exit

Hope that helped.

Answer 2

As @DerStoffel said, you have to start elasticsearch as a service ( sudo service elasticsearch start ). This is highly recommended in production settings. Also add the service to start in case of reboot ( sudo /sbin/chkconfig --add elasticsearch )

Answer 3

It depends the distribution of linux you use:

Debian/Ubuntu

sudo update-rc.d elasticsearch defaults 95 10
sudo /etc/init.d/elasticsearch start

RPM based distributions like Centos

sudo /sbin/chkconfig --add elasticsearch
sudo service elasticsearch start

Answer 4

sudo /bin/systemctl daemon-reload

sudo /bin/systemctl enable elasticsearch.service

sudo /bin/systemctl start elasticsearch.service
