ubuntu24.0离线安装Ollama和纯cpu版本以及对接Spring AI

---

一.官网下载 0.3.13版本

ollama离线安装包下载地址

---

二.将文件包上传至ubuntu服务器

---

三.下载安装脚本

curl -fsSL https://ollama.com/install.sh

修改远程拉取ollama代码为本地解压
源需要修改的脚本代码如下

if curl -I --silent --fail --location "https://ollama.com/download/ollama-linux-${ARCH}.tgz${VER_PARAM}" >/dev/null ; thenstatus "Downloading Linux ${ARCH} bundle"curl --fail --show-error --location --progress-bar \"https://ollama.com/download/ollama-linux-${ARCH}.tgz${VER_PARAM}" | \$SUDO tar -xzf - -C "$OLLAMA_INSTALL_DIR"BUNDLE=1if [ "$OLLAMA_INSTALL_DIR/bin/ollama" != "$BINDIR/ollama" ] ; thenstatus "Making ollama accessible in the PATH in $BINDIR"$SUDO ln -sf "$OLLAMA_INSTALL_DIR/ollama" "$BINDIR/ollama"fi
elsestatus "Downloading Linux ${ARCH} CLI"curl --fail --show-error --location --progress-bar -o "$TEMP_DIR/ollama"\"https://ollama.com/download/ollama-linux-${ARCH}${VER_PARAM}"$SUDO install -o0 -g0 -m755 $TEMP_DIR/ollama $OLLAMA_INSTALL_DIR/ollamaBUNDLE=0if [ "$OLLAMA_INSTALL_DIR/ollama" != "$BINDIR/ollama" ] ; thenstatus "Making ollama accessible in the PATH in $BINDIR"$SUDO ln -sf "$OLLAMA_INSTALL_DIR/ollama" "$BINDIR/ollama"fi
fi

新改后代码

status "Downloading Linux ${ARCH} bundle"
#    curl --fail --show-error --location --progress-bar \
#        "https://ollama.com/download/ollama-linux-${ARCH}.tgz${VER_PARAM}" | \
$SUDO tar -xzf ./ollama-linux-amd64.tgz -C "$OLLAMA_INSTALL_DIR"
BUNDLE=1
if [ "$OLLAMA_INSTALL_DIR/bin/ollama" != "$BINDIR/ollama" ] ; thenstatus "Making ollama accessible in the PATH in $BINDIR"$SUDO ln -sf "$OLLAMA_INSTALL_DIR/ollama" "$BINDIR/ollama"
fi

四.剔除GPU相关下载ROCM等，纯CPU运行脚本

在题目3的基础上，又剔除了GPU部分，即从wls2注释将下面全部删除

完整版 离线基于CPU的运行脚本

五.ollama常用命令

# 关闭ollama服务
service ollama stopollama serve # 启动ollama
ollama create # 从模型文件创建模型
ollama show  # 显示模型信息
ollama run qwen2.5:3b-instruct-q4_K_M  # 运行模型，会先自动下载模型
ollama pull  # 从注册仓库中拉取模型
ollama push  # 将模型推送到注册仓库
ollama list  # 列出已下载模型
ollama ps  # 列出正在运行的模型
ollama cp  # 复制模型
ollama rm  # 删除模型

六. 远程测试

建议生产不开启，因为没有token等限制，必须注意接口调用安全
1.首先停止ollama服务：

systemctl stop ollama

2.修改ollama的service文件：

vim /etc/systemd/system/ollama.service

3.新增Environment="OLLAMA_HOST=0.0.0.0:11434"

[Unit]
Description=Ollama Service
After=network-online.target[Service]
ExecStart=/usr/local/bin/ollama serve
User=ollama
Group=ollama
Restart=always
RestartSec=3
Environment="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin"
Environment="OLLAMA_HOST=0.0.0.0:11434"[Install]
WantedBy=default.target

4. 启动ollama

systemctl daemon-reload
systemctl start ollama
# 若启动失败可以使用 ollama serve测试

七.对接spring AI

    <dependencyManagement><dependencies><!--spring boot依赖--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-dependencies</artifactId><version>${spring.boot.version}</version><type>pom</type><scope>runtime</scope></dependency><dependency><groupId>org.springframework.ai</groupId><artifactId>spring-ai-bom</artifactId><version>1.0.0-SNAPSHOT</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><!-- https://mvnrepository.com/artifact/org.springframework.ai/spring-ai-ollama-spring-boot-starter --><dependency><groupId>org.springframework.ai</groupId><artifactId>spring-ai-ollama-spring-boot-starter</artifactId></dependency></dependencies><repositories><repository><id>spring-milestones</id><name>Spring Milestones</name><url>https://repo.spring.io/milestone</url><snapshots><enabled>false</enabled></snapshots></repository><repository><id>spring-snapshots</id><name>Spring Snapshots</name><url>https://repo.spring.io/snapshot</url><releases><enabled>false</enabled></releases></repository></repositories>

若以上代码无法拉取，可能被setting.xml全局拦截到镜像站。 以上spring ai还未发布到maven中央仓库请参考maven多仓库私库模板配置
