Install and configure the network detection tool smokeping

Smokeping is the work of Tobi oetiker by MRTG and rrdtool. It is mainly used to check the network quality and stability of the IDC. Its main functions include general Ping, dig, echoping, and curl, use rrdtool to draw images. I think there are the following reasons for choosing smokeping:

1. the best drawing function, latency and packet loss are intuitively indicated by color and shadow.

2. Free and open-source.

3. Supports the master-slave distributed mode.

4. You can customize the alarm function.

Smokeping Official Website: http://oss.oetiker.ch/smokeping/

The following installation and configuration systems are: RedHat 5.8 + Perl 5.8.8

Smokeping official Perl version requirements: Perl 5.8.8 or later

1. Installation

Http://oss.oetiker.ch/smokeping/pub/

1. Install the yum source. The rpmforge source has the dependent packages required for smokeping:

# Rpm-UHV http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

After the installation is successful, one more repo file is configured in the yum Repository:

[[Email protected] _ 82_215 soft] # ls/etc/yum. Repos. d/
5as. Repo 5asu5. Repo mirrors-rpmforge RedHat. Repo rhel-debuginfo.repo rpmforge. Repo

2. Install the dependency package:

# Yum install httpd

# Yum install rrdtool

# Yum install fping

# Yum install echoping

# Yum install curl

# Yum install Perl-net-Telnet Perl-net-DNS Perl-LDAP Perl-libwww-perl Perl-radiusperl Perl-io-socket-SSL perl-Socket6 Perl-CGI-speedycgi

3. Install the latest version of 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

Note:

1. After configure, if the dependent Perl module is not properly installed, a script is prompted for installation. Run the script as prompted. If there are still problems after the script is run, refer to the 2nd

2. If the following error occurs during configure, The fcgi module is not installed:

Checking for Perl module 'fcgi'... failed
Checking for Perl module 'cgi '... OK
Checking for Perl module 'cgi: quick'... failed

Install the fcgi module:

# Perl-mcpan-e 'Install fcgi'

If you are prompted that CPAN is not installed, use yum for installation.

# Yum install CPAN

Then install:

#./Configure -- prefix =/opt/smokeping

# Make install

View the installation directory:

[[Email protected] _ 82_215 smokeping] # ls
Bin etc htdocs lib share thirdparty

4. There are many configuration files ending with DIST in the smokeping directory. You need to rename the files ending with DIST to make the configuration take effect:

# 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

2. Modify the smokeping and Apache configuration files.

1. Modify the Binary command permission:

# Chmod 4775/bin/Traceroute

2. Create the following three directories to save the smokeping data.

# 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. Specify the path to the Perl module library of rrdtool.

First, find the location of the library file on the system: (the installation method of different systems or different Perl-rrdtool will be different)

Put the following lines:

# Use lib QW (); # perl5lib

To:
Use lib QW (/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/auto/rrds); # perl5lib

4. Modify the Apache configuration file

# Vim/etc/httpd/CONF/httpd. conf

Add the following VM:

<Virtualhost *: 80>
Serveradmin [email protected]
Servername 10.13.82.215
DocumentRoot/opt/smokeping/htdocs
Errorlog logs/174-error_log
Customlog logs/174-access_log common
<Directory "/opt/smokeping/htdocs">
Options followsymlinks execcgi
AllowOverride none
Directoryindex index.html smokeping. fcgi
Addhandler CGI-script fcgi. cgi
Order allow, deny
Allow from all
</Directory>
</Virtualhost>

Restart Apache:

#/Etc/init. d/httpd restart

5. Modify the smokeping configuration file.

Note:

1) the configuration file if there is Chinese, not only the above configuration file to set charset = UTF-8, the system also needs to set the Chinese Character Set in/etc/profile add export lang = zh_CN.UTF-8, in addition, all xshell or CRT interruptions must be set to UTF-8, so that the editing of Chinese in the configuration file and the display of Chinese on the access page will not be affected.

2), configuration details can refer to the official website: http://oss.oetiker.ch/smokeping/doc/smokeping_config.en.html

6. Restart script Customization

# Vim/etc/init. d/smokeping

Add the following content:

#! /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

Add execution permission

# Chmod + x/etc/init. d/smokeping

7. Start the smokeping service.

Normal start:

#/Etc/init. d/smokeping start

Or

#/Opt/smokeping/bin/smokeping

When debugging a fault, start in debug mode:

/Opt/smokeping/bin/smokeping -- Config =/opt/smokeping/etc/config -- debug

3. Access the page

Http: // 10.13.82.215/

The page effect is as follows:
