如何快速关闭Linux上的服务脚本

前言

对于开发而言，生产部署调试是家常便饭，尤其学习一个新的技术，常常是多个服务共同调试，那么如何快速关闭服务，尤其未将服务添加进环境变量的时候。

关闭Linux指定服务脚本

创建并编辑 find_and_kill.sh 文件；

$ vi find_and_kill.sh

如下内容复制粘贴进文件中：

#!/bin/bash
# 查找输入服务名的进程id，并结束它
# Check if a string argument is provided
if [ -z "$1" ]; thenecho "Usage: $0 <string>"exit 1
fiinput_string="$1"# Find the process ID(s) containing the input string
pids=$(ps aux | grep "$input_string" | grep -v "grep" | grep -v "$0" | awk '{print $2}')# Check if any processes were found
if [ -z "$pids" ]; thenecho "No process found containing the string '$input_string'."exit 1
fi# Output the process ID(s)
echo "Process ID(s) for string '$input_string':"
echo "$pids"# Optionally, ask the user if they want to kill the process(es)
read -p "Do you want to kill these process(es)? (y/n): " confirm
if [ "$confirm" = "y" ]; thenfor pid in $pids; dokill "$pid" && echo "Killed process $pid" || echo "Failed to kill process $pid"done
fi

文件加入写权限，表明是一个可执行文件：

$ chmod +x find_and_kill.sh 

文件执行测试：

$ ./find_and_kill.sh nacos
Process ID(s) for string 'nacos':
3175
Do you want to kill these process(es)? (y/n): y
Killed process 3175
