Ubuntu20.04 设置开机自启，指定普通用户执行脚本

1、参考

Ubuntu20.04 设置开机自启
rc.local里指定用户来运行程序

2、查看java环境

#set Java environmen
export JAVA_HOME=/usr/local/java/jdk1.8.0_161
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=/usr/bin:${JAVA_HOME}/bin:$PATH

3、配置启动jar脚本

更改文件所有者
sudo chown bjlthy:bjlthy start_tils.sh
更改文件夹所有者
sudo chown bjlthy:bjlthy TILS/

#!/bin/bash
. /etc/profile
killall java
sleep 1
cd /usr/local/java/jdk1.8.0_161/bin/
#nohup java -jar /home/bjlthy/Java/TILS/File/tils.jar > /home/bjlthy/Java/TILS/File/tils.jarLog.txt 2>&1 &
java -jar /home/bjlthy/Java/TILS/File/tils.jar &
echo '============= end'

4、配置 rc.local

sudo vim /etc/rc.local 在文件exit 0前追加

/bin/su - bjlthy -c "/home/bjlthy/Java/start_tils.sh&"
 
exit 0

5、其它

C程序 rc.local启动失败，临时性方案，在/etc/profile 添加

#set Java environmen
export JAVA_HOME=/usr/local/java/jdk1.8.0_161
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=/usr/bin:${JAVA_HOME}/bin:$PATH
export PATH=/usr/local/cuda/bin:$PATH
export PATH=$PATH:/sbin:/usr/bin:/usr/sbin
 
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/bjlthy/gym/xiaojihan/hwdecodelib/flowDecode/lib
#killall fftest
if [ "$(ps -ef |grep fftest |wc -l)" -eq 1 ]; then
	/home/bjlthy/gym/xiaojihan/hwdecodelib/fftest &
fi
