Perfect solution without rc. local file in Linux

Newer Linux releases no longer have rc. local files. Because it has been serviced.

Solution:

1. Set rc-local. service

sudo vim /etc/systemd/system/rc-local.service
[Unit]
 Description=/etc/rc.local Compatibility
 ConditionPathExists=/etc/rc.local
[Service]
 Type=forking
 ExecStart=/etc/rc.local start
 TimeoutSec=0
 StandardOutput=tty
 RemainAfterExit=yes
 SysVStartPriority=99
[Install]
 WantedBy=multi-user.target

2. Activate rc-local. service

sudo systemctl enable rc-local.service

3. Add startup service

Manually create or copy existing ones /etc/rc.local And give execution permission

#!/bin/sh -e
# 
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

#  The following is the command to boot 
/home/selfcs/anaconda3/bin/python /home/selfcs/t.py > /home/selfcs/auto.log 

exit 0
# Give script execution permission 
sudo chmod +x /etc/rc.local
