以ngrok為例,在centos7上寫一個服務

首先要先編輯你要的服務 服務通常會在/etc/systemd/system/底下

vim /etc/systemd/system/ngrok.service

寫入:

[Unit]
Description=ngrokd Daemon
after=network.target

[Service]
Type=forking
ExecStart=/home/ngrokd-start.sh
ExecStop=/home/ngrokd-stop.sh
StandardOutput=tty

[Install]
WantedBy=multi-user.target

回到home目錄 創建ngrokd-start.sh 跟 ngrokd-stop.sh (別忘了要chmod改一下權限) ngrokd-start.sh 內容:

#!/bin/sh
/home/ngrok http 1880 -log=./log.txt &

ngrokd-stop.sh 內容:

#!/bin/sh
ps aux | grep ngrok | awk '{print $2}' | xargs kill -9

記得寫完要 systemctl daemon-reload
