Linux boot self-starting.sh script (simple and rude)

1. Simple script

1. Create a script

(1) #Switch to the directory where you will save the script

cd /root/bigdata/install/

(2) Write the script autorun.sh

The following is the script content:

(The execution script means to create an input.txt folder in the /home directory and write the current date and hostname)

#!/bin/bash
date >> /home/input.txt
hostname >> /home/input.txt

 2. Add the script to the startup file

Execute the following command:

cd /etc/rc.d
vi rc.local

Add the script you wrote in the last line (write from the root directory)

/root/bigdata/install/autorun.sh

3. Grant permissions

chmod +x /etc/Your rc.local file address needs to add the file name Example: (/etc/rc.d/rc.local)

chmod +x You need to add the file name to the address where the sh file is stored Example: (/root/bigdata/install/autorun.sh) 

 4. Restart Linux

sudo reboot

 5. Check the effect

cat input.txt

 2. Start the jar package script

1. Write the jar package startup script

#!/bin/sh
export JAVA_HOME=/bigdata/install/jdk-1.8.0/
export PATH=$JAVA_HOME/bin:$PATH
cd /root/bigdata/install
echo "开机启动">log.log
nohup java -jar demo01-0.0.1-SNAPSHOT.jar >>log.log 2>&1 &

Other steps are the same as above

Check whether the jar is automatically started by typing: ps -ef|grep jar
