kali添加開機自啟
采用systemd的方法，kali默認是沒有rc.local的，需要自己創建。本方法也適用於ubuntu 18.04 64bit
改寫rc-local.service 文件
先從lib中拿出模板文件進行更改
sudo cp /lib/systemd/system/rc-local.service /etc/systemd/system/rc-local.service
再vim修改
sudo vim /etc/systemd/system/rc-local.service
主要是添加[install]復制最下面的[install]即可

創建/etc/rc.local文件
sudo vim /etc/rc.local

/home/ki/桌面/frp_0.36.2_linux_amd64/frpc -c /home/ki/桌面/frp_0.36.2_linux_amd64/frpc.ini &
exit 0
注意，注釋到執行代碼這片區域中間不要有空行。不然該服務會將空行當命令執行，所以就會報錯。命令后面我加上
&是表示在后台執行
設置執行權限
sudo chmod a+x /etc/rc.local
檢查腳本是否正確
含義分別是重載服務，啟動服務，查看服務狀態
sudo systemctl enable rc-local
sudo systemctl start rc-local.service
sudo systemctl status rc-local.service
可能出現的問題
- 出現active，但是下面日志出現報錯
則你的systemd服務順利執行了。但是你的/etc/rc.local腳本有問題。自己執行下這個命令看看能不能正確執行該腳本。不能那就檢查腳本代碼，注意不要出現空行。重新檢查文件執行權限
./etc/rc.local
- 沒顯示active
那么就是你的/etc/systemd/system/rc-local.service 寫的不對。重新檢查下，特別是[install]部分
