基于类似主题的回答https://askubuntu.com/a/58406我更喜欢:/etc/init.d / postgres状态

如果你运行下面的命令，你会得到一个服务列表:

sudo service --status-all

获取upstart任务列表:

sudo initctl list

最好的方法是在终端中使用nmap工具。 nmap是一个有用的工具，它可以分析一个up系统，使用它的IP地址，然后显示所有激活的网络服务。

打开终端和使用本例:

~$ 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).
Not shown: 994 closed ports
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

在linux操作系统中查询某项服务的状态。

//in case of super user(admin) requires    
sudo service {service_name} status 
// in case of normal user
service {service_name} status 

停止或启动服务

// in case of admin requires
sudo service {service_name} start/stop
// in case of normal user
service {service_name} start/stop 

获取所有服务和PID的列表:

sudo service --status-all

你可以使用systemctl代替直接调用service:

systemctl status/start/stop {service_name}

对于centos，下面的命令对我有用(:

locate postgres | grep service

输出:

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

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

sudo systemctl status postgresql-9.3.service

查找正在运行的服务的肮脏方法。(有时它是不准确的，因为一些自定义脚本没有|状态|选项)
