网络检测工具smokeping安装配置
smokeping是MRTG和RRDtool作者Tobi Oetiker的作品，主要用于对IDC网络质量，稳定性等做检测，主要功能包括常规的ping，dig，echoping，curl等，依赖rrdtool来画图。选择smokeping我觉得有以下原因：1，最佳的画图功能，延迟和丢包用颜色和阴影表示很直观。
2，免费和开源。
3，支持主从的分布式模式。
4，可以自定义报警功能。
smokeping官方网站：http://oss.oetiker.ch/smokeping/
如下安装配置的系统为:redhat 5.8 + Perl 5.8.8
smokeping官方对perl版本要求：Perl 5.8.8 or later
一，安装
官方下载地址：http://oss.oetiker.ch/smokeping/pub/
1，安装yum源，这个rpmforge源中有smokeping所需的依赖包：
# rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
安装成功之后会在yum仓库配置中多一个repo文件：
# ls /etc/yum.repos.d/
5AS.repo5ASU5.repomirrors-rpmforgeredhat.reporhel-debuginfo.reporpmforge.repo
2，安装依赖包：
# yum install httpd
# yum install rrdtool
# yum install fping
# yum install echoping
# yum install curl
# yum install perl perl-Net-Telnet perl-Net-DNS perl-LDAP perl-libwww-perl perl-RadiusPerl perl-IO-Socket-SSL perl-Socket6 perl-CGI-SpeedyCGI
3，安装最新版smokeping：
# wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.9.tar.gz
# tar xf smokeping-2.6.9.tar.gz
# cd smokeping-2.6.9/
# ./configure --prefix=/opt/smokeping
注意：
1，configure之后，如果依赖的perl module没有安装好，会提示用脚本进行安装。根据提示，直接运行脚本即可。如果脚本运行之后，仍然有问题，参考第2条
2，如果configure时候，出现如下报错，则是FCGI模块没有安装：
checking checking for perl module 'FCGI'... Failed
checking checking for perl module 'CGI'... Ok
checking checking for perl module 'CGI::Fast'... Failed
安装FCGI模块：
# perl -MCPAN -e 'install FCGI'
如果提示未安装cpan，则用yum进行安装
# yum install cpan
然后在安装：
# ./configure --prefix=/opt/smokeping
# make install
查看安装目录：
# ls
binetchtdocslibsharethirdparty
4，在smokeping目录中有很多以dist结尾的配置文件，需要把dist结尾的文件重命名，配置才能生效：
# cd htdocs
# cp smokeping.fcgi.dist smokeping.fcgi
# cp tr.cgi.dist tr.cgi
# cd ../etc/
# cp config.dist config
# cp basepage.html.dist basepage.html
# cp smokemail.dist smokemail
# cp tmail.dist tmail
# cp smokeping_secrets.dist smokeping_secrets
# chmod 600 /opt/smokeping/etc/smokeping_secrets
二，修改smokeping和apache配置文件
1，修改二进制命令权限：
# chmod 4775 /bin/traceroute
2，建立下面三个目录用于保存smokeping的数据等
# mkdir /opt/smokeping/data
# mkdir /opt/smokeping/var
# mkdir /opt/smokeping/htdocs/cache
# mkdir -p /opt/smokeping/htdocs/img
# chown -R apache:apache /opt/smokeping
3，指定rrdtool的perl模块库文件路径
先找到系统上库文件位置：（不同系统或者不同的perl-rrdtool的安装方法，位置会不同）
# rpm -qa|grep rrdtool
perl-rrdtool-1.4.7-1.el5.rf
rrdtool-1.2.27-4.el5
rrdtool-1.4.7-1.el5.rf
# rpm -ql perl-rrdtool-1.4.7-1.el5.rf
/usr/lib/perl5/vendor_perl/5.8.8/RRDp.pm
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/RRDs.pm
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/auto/RRDs/RRDs.bs
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/auto/RRDs/RRDs.so
/usr/share/doc/perl-rrdtool-1.4.7
/usr/share/doc/perl-rrdtool-1.4.7/MANIFEST
/usr/share/doc/perl-rrdtool-1.4.7/README
/usr/share/man/man3/RRDp.3pm.gz
/usr/share/man/man3/RRDs.3pm.gz
# vim /opt/smokeping/bin/smokeping_cgi
把如下行：
#use lib qw(); # PERL5LIB
修改为：
use lib qw(/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/auto/RRDs); # PERL5LIB
4，修改apache配置文件
# vim /etc/httpd/conf/httpd.conf
添加下面虚拟主机：
ServerAdmin root@localhost
ServerName 10.13.82.215
DocumentRoot /opt/smokeping/htdocs
ErrorLog logs/174-error_log
CustomLog logs/174-access_log common
Options FollowSymLinks ExecCGI
AllowOverride None
DirectoryIndex index.html smokeping.fcgi
AddHandler cgi-script fcgi .cgi
Order allow,deny
Allow from all
重启apache：
# /etc/init.d/httpd restart
5，修改smokeping配置文件
# vim config

#如下所示，定义多个FPing，然后在最下面node定义的时候（如下配置中的红色字体），使用不同的probe，就实现了探测的多进程，多与机器多的检测，提升了效率。

注意：
1）,配置文件如果有中文的话，不仅如上配置文件中要设置charset=UTF-8，系统也要设置中文字符集在/etc/profile中加入export LANG=zh_CN.UTF-8，并且所有的xshell或者crt中断也要设置成utf-8格式，这样就不会影响中文在配置文件中的编辑和中文在访问页面的展示。
2）,配置的详细信息可以参考官方网站：http://oss.oetiker.ch/smokeping/doc/smokeping_config.en.html
6，重启脚本定制
# vim /etc/init.d/smokeping
添加如下内容：
#!/bin/bash
#
# chkconfig: 2345 80 05
# Description: Smokeping init.d script
# Hacked by : How2CentOS - http://www.how2centos.com
# Get function from functions library
. /etc/init.d/functions
# Start the service Smokeping
start() {
echo -n "Starting Smokeping: "
/opt/smokeping/bin/smokeping >/dev/null 2>&1
### Create the lock file ###
touch /var/lock/subsys/smokeping
success $"Smokeping startup"
echo
}
# Restart the service Smokeping
stop() {
echo -n "Stopping Smokeping: "
kill -9 `ps ax | grep "/opt/smokeping/bin/smokeping" | grep -v grep | awk '{ print $1 }'` >/dev/null 2>&1
### Now, delete the lock file ###
rm -f /var/lock/subsys/smokeping
success $"Smokeping shutdown"
echo
}
### main logic ###
case "$1" in
start)
start
;;
stop)
stop
;;
status)
status smokeping
;;
restart|reload|condrestart)
stop
start
;;
*)
echo $"Usage: $0 {start|stop|restart|reload|status}"
exit 1
esac
exit 0
增加执行权限
# chmod +x /etc/init.d/smokeping
7，smokeping服务启动
正常启动：
# /etc/init.d/smokeping start
或
# /opt/smokeping/bin/smokeping
调试故障时，使用debug模式启动：
/opt/smokeping/bin/smokeping --config=/opt/smokeping/etc/config --debug
