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)

[root@server ~]# for qw in `ls /etc/init.d/*`; do  $qw status | grep -i running; done

如果你特别寻找postgres有一个特殊的命令叫做pgrep 你可以在下面的文章中找到它的用法 https://mydbanotebook.org/post/troubleshooting-01/

本文提供了以下细节: 检查postgres服务器是否正在运行 postgres在哪里存储所有的服务器配置 如何启动/停止postgres

希望这对大家有帮助

您可以使用以下命令查看所有服务的列表。

ps aux 

检查您自己的服务:

ps aux | grep postgres

run

Ps -ef | grep名称与进程相关

上面的命令将给出有关进程的所有细节，如pid，开始时间。

如果你想要所有与Java相关的进程，就给Java 或者，如果你有进程名，就写上进程名

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}
