1、在线安装
在线安装地址https://ollama.com/download选择服务器系统，按照步骤完成安装
2、离线安装
步骤1：查看服务器CPU的型号
## 查看Linux系统CPU型号命令，我的服务器cpu型号是x86_64lscpu
步骤2：根据CPU型号下载Ollama安装包，并保存到/home/Ollama目录
我下载的是Ollama的v0.1.31版本，后面均以此版本为例说明
下载地址 https://github.com/ollama/ollama/releases/
# x86_64 CPU选择下载ollama-linux-amd64# aarch64|arm64 CPU选择下载ollama-linux-arm64
步骤3：离线下载Linux环境的Ollama安装脚本，并保存到/home/Ollama目录
## 下载地址1，浏览器中打开下面地址https://ollama.com/install.sh## 下载地址2https://github.com/ollama/ollama/blob/main/scripts/install.sh## 国内加速可访问https://gitee.com/ai-big-model/ollama/blob/main/scripts/install.sh步骤4：修改install.sh脚本
总共需要修改两个点，第一：Ollama下载地址；第二：Ollama安装包存放目录
第一处修改，注释下载链接
status "Downloading ollama..."## 在install.sh的第65行#curl --fail --show-error --location --progress-bar -o $TEMP_DIR/ollama "https://ollama.com/download/ollama-linux-${ARCH}${VER_PARAM}"第二处修改，修改ollama安装目录

步骤5：配置大模型下载目录
# 执行命令vim ~/.bashrc# 配置 OLLAMA_MODELS 环境变量自定义路径### ollama model dir 改为自定义的路径，默认路径/usr/share/ollama/.ollama/models export OLLAMA_MODELS=/home/Ollama/ollama_cache# 复制/usr/share/ollama/.ollama/models目录中（blobs manifests）的文件夹到OLLAMA_MODELS环境变量目录cp -r /usr/share/ollama/.ollama/models /home/Ollama/ollama_cache步骤6：运行大模型，如通义千问
# 需要先将大模型下载到OLLAMA_MODELS文件中# ollama run <模型名称>ollama run qwen步骤7：关闭 Ollama 服务
# 关闭ollama服务service ollama stop
