Debian 10 把 rc.local 加回來

首先我們需要先自行創建 rc.local 檔案，可直接使用下面代碼快速建立

cat <<EOF >/etc/rc.local
#!/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.

exit 0
EOF

接著我們賦予 rc.local 可執行的權限

chmod +x /etc/rc.local

再來就可以啟動 rc-local 服務了

systemctl start rc-local

觀察看看是否有正確運作

systemctl status rc-local
