Check If a Particular Service Is Running on Ubuntu

问题:

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 not, but I don't know the service's name, then how could I check its status?

I know the command to check the status if the service name is known.

回答1:

I don't have an Ubuntu box, but on Red Hat Linux you can see all running services by running the following command:

service --status-all

On the list the + indicates the service is running, - indicates service is not running, ? indicates the service state cannot be determined.

回答2:

For Ubuntu (checked with 12.04)

You can get list of all services and select by color one of them with 'grep':

sudo service --status-all | grep postgres

Or you may use another way if you know correct name of service:

sudo service postgresql status

回答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

回答4:

If you run the following command you will get a list of services:

sudo service --status-all

To get a list of upstart jobs run this command:

sudo initctl list

回答5:

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

systemctl status service_name

Try:

systemctl status postgres

回答6:

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

ps aux 

To check your own service:

ps aux | grep postgres

the best way is using of nmap tool in terminal. nmap is an useful tool that analyse an up system, using it's IP Address, then show all actived network services.

open terminal and use of this example :

~$ nmap 192.168.1.3/24

Starting Nmap 5.21 ( http://nmap.org ) at 2016-05-16 22:49 IRDT
Nmap scan report for 192.168.1.3
Host is up (0.00020s latency).

PORT     STATE SERVICE
22/tcp   open  ssh
23/tcp   open  telnet
139/tcp  open  netbios-ssn
445/tcp  open  microsoft-ds
3389/tcp open  ms-term-serv
3689/tcp open  rendezvous

回答8:

run

ps -ef | grep name-related-to-process

above command will give all the details like pid, start time about the process.

like if you want all java realted process give java or if you have name of process place the name

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...

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
