How to check if a particular service is running on Ubuntu

Question

I do not know the service\'s name, but would like to stop the service by checking its status.

For example, if I want to check if the PostgreSQL service is running or no

Answer 1

There is a simple way to verify if a service is running

systemctl status service_name

Try PostgreSQL:

systemctl status postgresql

Answer 2

Dirty way to find running services. (sometime it is not accurate because some custom script doesn't have |status| option)

[root@server ~]# for qw in `ls /etc/init.d/*`; do  $qw status | grep -i running; done
auditd (pid  1089) is running...
crond (pid  1296) is running...
fail2ban-server (pid  1309) is running...
httpd (pid  7895) is running...
messagebus (pid  1145) is running...
mysqld (pid  1994) is running...
master (pid  1272) is running...
radiusd (pid  1712) is running...
redis-server (pid  1133) is running...
rsyslogd (pid  1109) is running...
openssh-daemon (pid  7040) is running...

Answer 3

Maybe what you want is the ps command;

ps -ef

will show you all processes running. Then if you have an idea of what you're looking for use grep to filter;

ps -ef | grep postgres

Answer 4

You can use the below command to check the list of all services.

ps aux 

To check your own service:

ps aux | grep postgres

Answer 5

For centos, below command worked for me (:

locate postgres | grep service

Output:

/usr/lib/firewalld/services/postgresql.xml

/usr/lib/systemd/system/postgresql-9.3.service

sudo systemctl status postgresql-9.3.service

Based on this answer on a similar topic https://askubuntu.com/a/58406
I prefer: /etc/init.d/postgres status
