Openwrt是个很自由的开源路由器系统，软件包支持几千个，功能很强大！
安装的方法主要有两种，telnet或者ssh连接后台安装和 页面安装。
下面的所有步骤的前提是当前的路由器已经联网！
telnet或ssh
原始的openwrt默认是没有密码的，只开启了telnet没有开启ssh，当第一次配置完用户名和密码后，关闭了telnet开启了ssh，用户可以随时连上路由器，下面我用ssh连接的。
Openwrt管理软件包的命令是opkg，下面是命令的帮助
root@Jack:/tmp/opkg-lists# opkg--help
opkg:unrecognized option `--help'
opkgmust have one sub-command argument
usage:opkg [options...] sub-command [arguments...]
wheresub-command is one of:
PackageManipulation:
update 升级 Update list ofavailable packages
upgrade <pkgs> 升级某一个软件 Upgrade packages
install <pkgs> 安装某一个软件 Install package(s)
configure <pkgs> 配置某一个软件 Configure unpacked package(s)
remove <pkgs|regexp> 删除软件 Remove package(s)
flag <flag> <pkgs> Flag package(s)
<flag>=hold|noprune|user|ok|installed|unpacked (one perinvocation)
InformationalCommands:
list 列出openwrt所有支持的软件包 List availablepackages
list-installed 列出本机已经安装的软件包 List installed packages
list-upgradable 列出可以升级的软件包 ist installed and upgradable packages
list-changed-conffiles List user modified configuration files
files <pkg> List files belonging to<pkg>
search <file|regexp> List package providing <file>
find <regexp> List packages whose name ordescription matches <regexp>
info[pkg|regexp] 显示软件包的信息 Display all info for <pkg>
status [pkg|regexp] 显示软件包的状态 Display all status for <pkg>
download<pkg> 下载一个软件包到当前目录 Download<pkg> to current directory
compare-versions <v1> <op><v2>

-f <conf_file> Use <conf_file> as the opkgconfiguration file
--conf <conf_file>
--cache <directory> Use a package cache
-d <dest_name> Use <dest_name> as the the rootdirectory for
--dest <dest_name> package installation, removal, upgrading.
<dest_name>should be a defined dest name from
theconfiguration file, (but can also be a
directory namein a pinch).

ForceOptions:
--force-depends Install/remove despite faileddependencies
--force-maintainer Overwrite preexisting config files
--force-reinstall Reinstall package(s)
--force-overwrite Overwrite files from other package(s)
--force-downgrade Allow opkg to downgrade packages
--force-space Disable free space checks
--force-postinstall Run postinstall scripts even in offlinemode
--force-remove Remove package even if prerm script fails
--noaction No action -- test only
--download-only No action -- downloadonly
--nodeps Do not follow dependencies
--nocase Perform case insensitivepattern matching
--force-removal-of-dependent-packages
Remove packageand all dependencies
--autoremove Remove packages that were installed
automaticallyto satisfy dependencies
-t Specify tmp-dir.
--tmp-dir Specify tmp-dir.
regexp could be something like 'pkgname*''*file*' or similar
e.g. opkg info 'libstd*' or opkg search'*libop*' or opkg remove 'libncur*'
