前期中部署了ollama 及deepseek-r1,为了有web界面访问，需要部署open-webui

系统要求是python3.11以上版本，

一、先升级openssl

1.安装依赖
yum install -y gcc gcc-c++ autoconf automake zlib zlib-devel pcre-devel

2.下载源码包并解压
wget https://www.openssl.org/source/openssl-1.1.1q.tar.gz
tar xzf openssl-1.1.1q.tar.gz 
cd openssl-1.1.1q

3.编译安装
./config
make && make install

4.配置lib库
echo "/usr/local/lib64/" >> /etc/ld.so.conf
ldconfig

5.备份旧版本openssl
mv /usr/bin/openssl /usr/bin/openssl.bak

6.将新版本openssl链接到/usr/bin
ln -s /usr/local/bin/openssl /usr/bin/openssl

版本检查
最后执行openssl version -a 可以查看升级后的新版本。

systemctl restart sshd

二、升级SQLite

# 下载最新源码
wget https://www.sqlite.org/2024/sqlite-autoconf-3450100.tar.gz
tar xvfz sqlite-autoconf-3450100.tar.gz
cd sqlite-autoconf-3450100# 编译安装
./configure
make
sudo make install

mv /usr/bin/sqlite3 /usr/bin/sqlite3_3.7.17
ln -s /usr/local/bin/sqlite3 /usr/bin/sqlite3
echo "/usr/local/lib" > /etc/ld.so.conf.d/sqlite3.conf
ldconfig

三、部署python3.11

先安装依赖环境

yum -y groupinstall "Development tools"
yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel psmisc libffi-devel
yum update -y
yum install -y perl-IPC-Cmd
yum install -y openssl openssl-devel
yum install -y zlib zlib-devel openssl-devel sqlite-devel bzip2-devel libffi libffi-devel gcc gcc-c++
yum install -y wget

下载python3.11上传到系统中，解压安装

tar -zxvf Python-3.11.11.tgz

cd python-3.11.11

./configure --prefix=/usr/local/python3  --with-openssl=/usr/local/openssl

make -j4 && make install

ln -s /usr/local/python3/bin/python3.11 /usr/bin/python3 # 安装完成之后 建立软链接 添加变量 方便在终端中直接用python3进的是python3的版本
ln -s /usr/local/python3/bin/pip3.11 /usr/bin/pip3 # Python3安装完成之后pip3也一块安装完成，不需要再单独安装同样给pip3建立软链接

#环境，这里不做修改
export PATH=/usr/local/python3/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/python3/lib:$LD_LIBRARY_PATH

验证

/usr/local/python3/bin/python3 -c "import sqlite3; print(sqlite3.sqlite_version)"

3、配置pip源，安装open-webui

pip3 config set install.trusted-host mirrors.aliyun.com

pip3 install -i https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple open-webui

pip3 install open-webui

find / -name  open-webui 

vim open-webui

加入

__import__('pysqlite3')
import sys
sys.modules['sqlite3'] = sys.modules.pop('pysqlite3')

创建链接

ln -s /usr/local/python3/bin/open-webui /usr/bin/open-webui

安装后运行：open-webui serve
