此处，我们以Ubuntu 16.04虚拟机为例讲述搭建方法，为防止环境冲突，请选择使用一台干净的虚拟机，若使用Ubuntu Server 16.04，可能会出现系统安装失败情况，若出现，请参考底部的参考链接。

另外，此教程中涉及到了部分文件的修改，我也对原项目进行了部分本地化，因此也可以直接获取我fork修改的项目进行搭建，项目地址：https://github.com/hebtuerror404/libc-database。欢迎Star~

本文中最后生成的配置结束的PVM虚拟机已上传至百度云盘，需要的自取即可，链接: https://pan.baidu.com/s/1mfG_ES4GzBrLyoGRerZDoA 密码: 9vpp

使用命令sudo apt-get update && sudo apt-get upgrade -y

⚠️：可以使用以下命令换源以加速下载

使用命令

此处推荐使用以下命令直接获取docker

docker成功安装后可以去阿里云官网获取镜像加速器，然后按照官网所述直接做如下配置即可。

然后运行sudo pip install docker-compose -i https://mirrors.aliyun.com/pypi/simple/安装docker-compose

⚠️：此处安装完成后，可能产生以下错误

此时可以使用which docker-compose来确定核心文件位置，然后建立符号链接即可。

首先运行以下命令获取nodejs

然后安装npm

使用命令git clone https://github.com/niklasb/libc-database.git获取此项目。

修改libc-database/searchengine/frontend/src/App.js

接下来进入项目文件夹并生成Web端主项目

⚠️：若npm安装过慢，可以尝试使用cnpm，官网对于cnpm的描述如下：

要使用cnpm则运行以下命令：

⚠️：若可以在虚拟机内部开启VPN以加速访问境外网站，请在此步开启。

使用以下命令获取/更新所有libc文件到本地，此步骤依据网络连接状况需要耗时30 min ~ 2 h，请耐心等待

./get arch命令可能极其缓慢，属于正常情况，请耐心等待~

./get rpm命令可能会因cpio错误而退出，属于正常情况，直接无视即可~

首先需要修改一系列文件，使之满足启动条件

修改libc-database/searchengine/nginx.conf

修改libc-database/searchengine/config.py

修改libc-database/searchengine/api.py

使用命令sudo docker-compose up -d

启动后可以使用docker ps检查启动情况

在/libc-database/searchengine下，执行python3.6 -m index ../db

建立完成后，使用curl -XGET 127.0.0.1:9200/_cat/indices/来测试索引建立情况

最后，在/libc-database/searchengine下使用/usr/sbin/nginx -c nginx.conf启动本地Ngnix服务

使用命令curl -X POST -H 'Content-Type: application/json' --data '{"symbols": {"strncpy": "db0", "strcat": "0x000000000d800"}}' http://127.0.0.1/api/find进行测试。

断开虚拟机网络，以验证本地状态下的服务可用性

执行下列命令即可
