linux服务开机自启动之一（simple方式）

systemd服务方式

run.sh脚本

#!/bin/bash

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:../lib;export LD_LIBRARY_PATH
HOME=/home/gb;export HOME

if [ -x ${HOME}/USB-Device-Mgr/USB-Device-Mgr/bin/USB-Device-Mgr ]
then
        if [ "`ps -e -o comm=CMD | cut -f 1 -d' '| grep USB-Device-Mgr |grep -v grep  | sort | tail -1 `" != "USB-Device-Mgr" ]
        then
             echo "Start USB-Device-Mgr ..."
             ${HOME}/USB-Device-Mgr/USB-Device-Mgr/bin/USB-Device-Mgr
        fi
else
        echo "${HOME}/USB-Device-Mgr/USB-Device-Mgr/bin/USB-Device-Mgr is not executed"

[Unit]
Description=My Service
After=network.target

[Service]

ExecStart=/home/gb/USB-Device-Mgr/USB-Device-Mgr/bin/run.sh
WorkingDirectory=/home/gb/USB-Device-Mgr/USB-Device-Mgr/bin/
Restart=always

[Install]
WantedBy=multi-user.target

注：Restart=always,在程序USB-Device-Mgr被kill掉时，服务将自动拉起USB-Device-Mgr

更新配置

root@gb:/etc/systemd/system#systemctl daemon-reload

启动服务

root@gb:/etc/systemd/system# 
root@gb:/etc/systemd/system# systemctl enable gb_usbdevicemgr.service 
Created symlink /etc/systemd/system/multi-user.target.wants/gb_usbdevicemgr.service → /etc/systemd/system/gb_usbdevicemgr.service.
