Quagga是一款功能比较强大的开源路由软件，支持rip,ripng,ospfv2,ospfv3，bgp等协议。目前最新版本为Quagga0.99.17。安装Quagga的目的是使装有linux(我采用的是Ubuntu10.04LTS)系统的电脑变成一台路由器，以便今后的实验。之所以选择Quagga是因为它的操作和Cisco的操作是比较相似的。今天用到的电脑需要多块网卡支持（至少两块）。

 安装Quagga

首先下载Quagga 0.99.17到硬盘，然后在终端输入

tar –zxvf quagga-0.99.17.tar.gz

进入目录

#cd quagga-0.99.17

配置

#./configure --enable-vtysh --enable-user=root --enable-group=root --enable-vty-group=root

上述命令为打开vty功能(CLI功能)并给予相应用户权限,另有一些初始化配置见文档中.配置完成后会有一些信息表明quagga安装完成后相关文件所在位置。

此时出现错误：

checking for syslog.h... yes

checking for wchar.h... yes

checking for wctype.h... yes

checking for sys/sysctl.h... yes

checking for sys/sockio.h... no

checking for kvm.h... no

checking for sys/conf.h... no

checking for ucontext.h... yes

checking for special C compiler options needed for large files... no

checking for _FILE_OFFSET_BITS value needed for large files... 64

checking for perl... /usr/bin/perl

checking for tputs in -ltermcap... yes

checking for main in -lreadline... no

configure: error: vtysh needs libreadline but was not found and usable on your system.

zinkin@zinkin-desktop:~/quagga/quagga-0.99.17$

zinkin@zinkin-desktop:~/quagga/quagga-0.99.17$ --enable-user=root

--enable-user=root: command not found

zinkin@zinkin-desktop:~/quagga/quagga-0.99.17$

zinkin@zinkin-desktop:~/quagga/quagga-0.99.17$ --enable-group=root

--enable-group=root: command not found

zinkin@zinkin-desktop:~/quagga/quagga-0.99.17$

注：
①./configure是用来检测你的安装平台的目标特征的（比如它会检查是否有编辑器、函数库，CC或GCC等等），并根据配置信息生产相应的makefile，它是个shell脚本。
②./configure –h 输入此命令会一一列出当前配置环境所有配置选项
③此输入选项含义为，启用相应服务程序，并对不用的服务程序进行关闭，其中--enable- user=root --enable-group=root 是限定quagg软件的使用权限。
④配置时易出现如下错误：
/usr/local/lib/libreadline.so: undefined reference to `PC'
/usr/local/lib/libreadline.so: undefined reference to `tgetflag'
/usr/local/lib/libreadline.so: undefined reference to `tgetent'
/usr/local/lib/libreadline.so: undefined reference to `UP'
/usr/local/lib/libreadline.so: undefined reference to `tputs'
/usr/local/lib/libreadline.so: undefined reference to `tgoto'
/usr/local/lib/libreadline.so: undefined reference to `tgetnum'
/usr/local/lib/libreadline.so: undefined reference to `BC'
/usr/local/lib/libreadline.so: undefined reference to `tgetstr'
checking for perl... /usr/bin/perl

       checking for tputs in -ltermcap... no

       checking for tputs in -ltinfo... no

       checking for tputs in -lcurses... no

       checking for tputs in -lncurses... no

       checking for main in -lreadline... no

       configure: error: vtysh needs libreadline but was not found and usable on your system
解决方法：
1    看readline软件包是否安装

sudo apt-get install libreadline5-dev

2    是否安装ncurses安装包

sudo apt-get install libncurses5-dev

3    是否安装libncurses5-dev 或libncursesw5-dev软件包

sudo apt-get install libncursesw5-dev

 
安装完成之后再重新用配置命令

#./configure --enable-vtysh --enable-user=root --enable-group=root --enable-vty-group=root

 

之后编译与安装

#make
#make install

 

之后出现错误

/usr/bin/install: cannot create regular file `/usr/local/lib/libprotobuf.so.0.0.0': Permission denied
make[3]: *** [install-libLTLIBRARIES] Error 1 make[3]: Exit from catalogue `/home/alexe/downloads/proto2/protobuf-2.0.0beta/src' make[2]: *** [install-am] Error 2 make[2]: Exit from catalogue `/home/alexe/downloads/proto2/protobuf-2.0.0beta/src' make[1]: *** [install] Error 2 make[1]: Exit from catalogue `/home/alexe/downloads/proto2/protobuf-2.0.0beta/src' make: *** [install-recursive] Error 1

可以采用

＃sudo make
＃sudo make install
＃sudo ldconfig

 

3.修改文件/etc/services,添加如下内容(某些版本Ubuntu已有,就不用添加了)

zebrasrv 2600/tcp # zebra service
zebra 2601/tcp # zebra vty
ripd 2602/tcp # RIPd vty
ripngd 2603/tcp # RIPngd vty
ospfd 2604/tcp # OSPFd vty
bgpd 2605/tcp # BGPd vty
ospf6d 2606/tcp # OSPF6d vty
ospfapi 2607/tcp # ospfapi
isid 2608/tcp # ISISd vty

 

之后查看/etc/services，这个文件，发现已经里面有上面这段东西了。

quagga文件夹下/zebra  /usr/local/etc目录下有一个zebra.conf.sample文件,需建立一个zebra.conf文件并把zebra.conf.sample内容copy进去.

 

启动Quagga

在终端输入zebra -d即可启动quagga。有可能出现以下错误：

zebra: error while loading shared libraries: libzebra.so.0: cannot open shared object file: No such file or directory

解决方法：

在/usr/local/lib下有

lrwxrwxrwx 1 root root 17 2010-06-21 01:52 libzebra.so -> libzebra.so.0.0.0

lrwxrwxrwx 1 root root 17 2010-06-21 01:52 libzebra.so.0 -> libzebra.so.0.0.0

-rwxr-xr-x 1 root root 778556 2010-06-21 01:52 libzebra.so.0.0.0

这可能是由于/lib库出现问题：则

zinkin@zinkin-desktop:~/quagga/quagga-0.99.17$ cd /usr/local/lib
zinkin@zinkin-desktop:/usr/local/lib$ cp libzebra.* /lib
zinkin@zinkin-desktop:/usr/local/lib$ sudo rm libzebra.*

 

在终端输入zebra -d即可启动quagga。

zinkin@zinkin-desktop:~/quagga/quagga-0.99.17$ zebra -d
privs_init: could not lookup user quagga

[root@localhost1

由于自己的程序没有在root下，所以有些语句前面得用sudo

zinkin@zinkin-desktop:~/quagga/quagga-0.99.17$ sudo zebra -d -u root -g root

zinkin@zinkin-desktop:~/quagga/quagga-0.99.17$ telnet localhost 2601
