注：这里面就指出了可执行文件是 /etc/rc.local 。
编辑 /etc/rc.local，如下：

#!/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.

# 单独开机运行stable diffusion时
source ~/anaconda3/etc/profile.d/conda.sh

conda activate sd

cd /www/wwwroot/sd

python launch.py --xformers --listen --enable-insecure-extension-access --no-half-vae --disable-nan-check

# 开机同时自动运行 stable diffusion、kohya、jupter时
/root/stable_diffusion/launch.sh
/root/kohya_ss/launch.sh
/root/.jupyter/launch.sh

exit 0

给 /etc/rc.local 文件添加执行权限：

chmod +x /etc/rc.local
