OpenWrt的ipk包安装

在 make menuconfig 进行裁减 OpenWrt 时，为了让系统更精小一点，我们会把部分功能以“模块”的方式编译，即不编入内核，只是在后期用户可以进行安装与卸载。

包安装示例

如下关于Lua的配置项：

其中 json4lua, lua-cjson, lua-copas, lua-coxpcall 是没有编入原生系统的。
在 make 完成之后。
在 bin/ar71xx/packages/ 路径下全是 ipk 安装包。其中上面对应的安装包就在 bin/ar71xx/packages/packages/ 目录下。
#--开发机--$ ls lua*lua-cjson_2.1.0-1_ar71xx.ipk
   lua-rs232_1.0.3-1_ar71xx.ipklua-copas_2.0.0-1_ar71xx.ipk
   luasocket_3.0-rc1-20130909-3_ar71xx.ipklua-coxpcall_1.15.0-1_ar71xx.ipk
   luasql-mysql_2.3.0-1_ar71xx.ipkluaposix_v33.2.1-4_ar71xx.ipk
   luasql-sqlite3_2.3.0-1_ar71xx.ipk 怎么安装到 OpenWrt上呢？
首先，用 scp 将 ipk 包发送到 OpenWrt 系统上。本人的 OpenWrt 的 IP 为 192.168.1.2，以 luasql 为例

#--开发机--$ scp luasql-mysql_2.3.0-1_ar71xx.ipk root@192.168.1.2:root@192.168.1.2's
password: <输入密码>
luasql-mysql_2.3.0-1_ar71xx.ipk                   100% 6441    6.3KB/s 00:00
SSH登入 OpenWrt，查看文件。luasql-mysql_2.3.0-1_ar71xx.ipk 已在 /root/ 目录下了。
#--OpenWrt---$ opkg install luasql-mysql_2.3.0-1_ar71xx.ipk
Installing luasql-mysql (2.3.0-1) to root...
Collected errors: * satisfy_dependencies_for: Cannot satisfy the following dependencies for luasql-mysql: *    libmysqlclient *  * opkg_install_cmd: Cannot install package luasql-mysql. Oops，出师不力（不用惊慌，这也是常常遇到的事儿）～缺 libmysqlclient 库。
那就看看 libmysqlclient 库的 ipk 包有没有。如果 bin/ar71xx/packages 路径下没有，则是 make menuconfig 时没有加进来。这时，修改配置，再make一下就会有了。

在 bin/ar71xx/packages/ 路径下 find 一下。
#--开发机---$ find -name "libmysqlclient*"./packages/libmysqlclient_5.1.73-1_ar71xx.ipk 有！那就不用再make一遍了。
同样，用 scp 将 libmysqlclient_5.1.73-1_ar71xx.ipk 文件传送到 OpenWrt。
#--开发机---$ scp libmysqlclient_5.1.73-1_ar71xx.ipk root@192.168.1.2: 再在 OpenWrt 的 SSH 里安装刚发送过来的 ipk 包。
#--OpenWrt---$ opkg install libmysqlclient_5.1.73-1_ar71xx.ipk Installing libmysqlclient (5.1.73-1) to root...Collected errors: * satisfy_dependencies_for: Cannot satisfy the following dependencies for libmysqlclient: *    uclibcxx *  * opkg_install_cmd: Cannot install package libmysqlclient. Oops～Again，libmysqlclient还依赖于uclibcxx库。安装 uclibcxx 库。
#--开发机---$ scp base/uclibcxx_0.2.4-1_ar71xx.ipk root@192.168.1.2: #--OpenWrt---$ opkg install uclibcxx_0.2.4-1_ar71xx.ipk Installing uclibcxx (0.2.4-1) to root...Configuring uclibcxx. uclibcxx库OK了

再来安装 libmysqlclient 库
#--OpenWrt---$ opkg install libmysqlclient_5.1.73-1_ar71xx.ipk
Installing libmysqlclient (5.1.73-1) to root...Configuring libmysqlclient. libmysqlclient库OK了。

最后安装 luasql 库
#--OpenWrt---$ opkg install luasql-mysql_2.3.0-1_ar71xx.ipk
Installing luasql-mysql (2.3.0-1) to root...Configuring luasql-mysql.
就这样，luasql 库安装完成了。
在 OpenWrt 系统的 /usr/lib/lua/ 目录下多出一个 luasql 目录，在该目录下有一个 mysql.so 文件。

启动 Lua 试试看：
#--OpenWrt---$ luaLua 5.1.5  Copyright (C) 1994-2012 Lua.org, PUC-Rio (double int32)> require 'luasql.mysql' 成功。

  opkg 的使用 opkg 有点类似地 ubuntu 中的 dpkg 包管理工具。

常见的用法是：安装、卸载软件包。
usage: opkg [options...] sub-command [arguments...]
where sub-command is one of
