smokeping 是由perl 写的一个用于实时监控外网网络的软件，通过rrd 生成图表监控,用于IDC网络的监控是非常有效果的
依赖包安装
yum install libxml2-devel libpng-devel pango pango-devel libart_lgpl libart_lgpl-devel freetype freetype-devel fontconfig cairo cairo-devel httpd httpd-devel perl-ExtUtils-MakeMaker perl-CGI perl-FCGI fping
rrd tool 以及绘图工具安装
tar -zxvf Config-Grammar-1.10.tar.gz
cd Config-Grammar-1.10
perl Makefile.PL
make && make install
tar zxvf rrdtool-1.4.3.tar.gz
cd rrdtool-1.4.3
./configure --prefix=/usr/local/rrdtool
make
make install
tar zxvf smokeping-2.6.8.tar.gz
安装smokeping
cd smokeping-2.6.8
./configure --prefix=/usr/local/smokeping
会有如下提示:
#checking checking for perl module 'RRDs'... Failed
#checking checking for perl module 'FCGI'... Ok
#checking checking for perl module 'CGI'... Ok
#checking checking for perl module 'CGI::Fast'... Ok
#checking checking for perl module 'Config::Grammar'... Failed
#checking checking for perl module 'Digest::HMAC_MD5'... Failed
#checking checking for perl module 'LWP'... Ok
说明对应的依赖包有问题，将之前装的rrdtool的pm 文件拷贝到smokeping下
cp /usr/local/rrdtool/lib/perl/5.10.1/x86_64-linux-thread-multi/RRDs.pm /usr/lib64/perl5/
cp /usr/local/rrdtool/lib/perl/5.10.1/x86_64-linux-thread-multi/auto/RRDs/RRDs.so /usr/lib64/perl5/
其他perl的关联包用下面这个去装
./setup/build-perl-modules.sh /usr/local/smokeping/thirdparty
之后gmake
gmake install
大多数会一切顺利，但如果本机的环境变量有设置过的话，有时候会爆一个以下的错误：
#Resetting LC_NUMERIC failed probably because your international setup of the LC_ALL to "en_US.UTF-8" is overridding LC_NUMERIC. Setting LC_ALL is not compatible with smokeping... at ../lib/Smokeping.pm line 44
看了下代码，这个感觉是个bug，可以改下Smokeping.pm 里面的变量，要改成当前env下的变量，LC_ALL=LC_ALL=en_US.UTF-8，然后gmake 就好了。
smokeping的页面访问方式是通过CGI 实现的，所以需要配置一下:
cd /usr/local/smokeping/
mkdir cache data var
chown apache.apache cache data var
cd /usr/local/smokeping/htdocs/
cp smokeping.fcgi.dist smokeping.fcgi
cd /usr/local/smokeping/etc/
cp config.dist config
chmod 400 /usr/local/smokeping/etc/smokeping_secrets.dist
ln -s /usr/local/smokeping/cache /usr/local/smokeping/htdocs/cache
同时修改对应的config 文件 ，/usr/local/smokeping/etc/config 并且启动：
/usr/local/smokeping/bin/smokeping --logfile=/var/log/smokeping.log
#修改apache
Alias /smokeping/ "/usr/local/smokeping/htdocs/"
<Directory "/usr/local/smokeping/">
AllowOverride None
Options All
AddHandler cgi-script .fcgi .cgi
Order allow,deny
Allow from all
DirectoryIndex smokeping.fcgi
</Directory>
/etc/init.d/apache restart
#重启apache
