Today my Opmanger server is down, I start it again but my service doesn’t start by automatic at boot time. So I need to start it by root permission at startup time. And this is my solution.
1. Write your script for start a service
#!/bin/bash echo "Start my service!!!"; cd /path/of/my/script/ ./run_my_script.sh
2. Change a permission file to execute
$ cd /path/of/my/script/ $ sudo chmod +x run_my_script.sh
3. Create a symbolic link file into /etc/init.d/
$ sudo ln -s /path/of/my/script/run_my_script.sh /etc/init.d/run_my_script.sh
4. Add this script into start up time
$ sudo update-rc.d run_my_script.sh defaults update-rc.d: warning: /etc/init.d/run_my_script.sh missing LSB style header Adding system startup for /etc/init.d/run_my_script.sh ... /etc/rc0.d/K20run_my_script.sh -> ../init.d/run_my_script.sh /etc/rc1.d/K20run_my_script.sh -> ../init.d/run_my_script.sh /etc/rc6.d/K20run_my_script.sh -> ../init.d/run_my_script.sh /etc/rc2.d/S20run_my_script.sh -> ../init.d/run_my_script.sh /etc/rc3.d/S20run_my_script.sh -> ../init.d/run_my_script.sh /etc/rc4.d/S20run_my_script.sh -> ../init.d/run_my_script.sh /etc/rc5.d/S20run_my_script.sh -> ../init.d/run_my_script.sh
5. Test by restart your server and check this process by ps -ef | grep run_my_script.sh
$ ps -ef | grep run_my_script.sh
