快速部署novelai画图

前段时间novelai犯了众怒被人脱了库，今天群友搭建了本地novelai端，并且免费开放了api接口，我们就沾沾光，借用群友提供的免费api快速部署novelai bot.(才不是因为买不起gpu服务器

配置python3.8

首先准备一台Centos7的主机

将系统自带的python2.7更换成python3.8

Centos7安装python3.8详细教程

安装编译相关工具

编译安装python

mkdir /usr/local/python3 #创建编译安装目录
cd Python-3.8.3
./configure --prefix=/usr/local/python3
make && make install

安装过,出现下面两行就成功了

创建软连接

# 查看当前python软连接
ll /usr/bin/ |grep python

lrwxrwxrwx    1 root root           7 Nov 26  2018 python -> python2
lrwxrwxrwx    1 root root           9 Nov 26  2018 python2 -> python2.7
-rwxr-xr-x      1 root root        7216 Jul 13  2018 python2.7

默认系统安装的是python2.7

删除python软连接
1
rm -rf /usr/bin/python
配置软连接为python3
1
2
#添加python3的软链接 
ln -s /usr/local/python3/bin/python3 /usr/bin/python

这个时候看下python默认版本

1
python -V #这里用的是大V

删除默认的pip软连接,并添加pip3新的软连接

3
rm -rf /usr/bin/pip
#添加 pip3 的软链接 
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip

更改yum配置

因为yum要用到python2.7才能执行,否则会导致yum不能正常使用(不管安装python3的哪个版本,都必须要更改以下配置)

vi /usr/bin/yum 
把 #! /usr/bin/python 修改为 #! /usr/bin/python2 
vi /usr/libexec/urlgrabber-ext-down 
把 #! /usr/bin/python 修改为 #! /usr/bin/python2
vi /usr/bin/yum-config-manager
#!/usr/bin/python 改为 #!/usr/bin/python2

git clone https://github.com/Ice-Cirno/HoshinoBot.git
cd HoshinoBot
pip install -r requirements.txt
# 如果上面的下载速度太慢，可以换源用下面的源
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple -r requirements.txt

如果提示这个：

# 先升级pip
pip install --upgrade pip
# 再执行安装
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple -r requirements.txt

就解决啦！

2.配置HoshinoBot

进入hoshino文件夹，将config_example文件夹复制一份，重命名为config，然后右键使用Notepad++打开其中的__bot__.py

image-20221008140031074

image-20221008132946597

进入/root/HoshinoBot/hoshino/modules目录，新建文件夹ai，并把novelai.py插件放到文件夹里。该插件我会放到文章末尾，需要的自取。
