smokeping for Centos7

I am using Centos7 + smokeping-2.6.9

lets start up by install needed package
before that, we will need to enable Epel repo
You can install EPEL by running yum install epel-release. The package is included in the CentOS Extras repository, enabled by default.

# yum install epel-release

Then follow up by the package for
  • mod_fcgid
  • httpd
  • httpd-devel
  • rrdtool
  • perl-CGI-SpeedyCGI
  • fping
  • rrdtool-perl
  • perl
  • perl-Sys-Syslog
# yum install mod_fcgid httpd httpd-devel rrdtool perl-CGI-SpeedyCGI fping rrdtool-perl perl perl-Sys-Syslog

Then we will needed some package for Cpan to install perl stuff

# yum install perl-CPAN perl-local-lib perl-Time-HiRes

The last one is the package to create installation for smokeping

# yum groupinstall "Development tools"
-----------------------------------------------------------------------------------------------------------------

Now lets download the latest smokeping at http://oss.oetiker.ch/smokeping/pub/
currently the latest i saw is 2.6.9, so i just download that

# wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.9.tar.gz

then extract it

# tar -zxvf smokeping-2.6.9.tar.gz

Install the smokeping perl stuff

# cd smokeping-2.6.9/setup
# ./build-perl-modules.sh

it will auto install needed perl
Once done, back to smokeping-2.6.9 folder and you will notice a folder name thirdparty is created
we will need to move it to /opt folder, but before that, lets create smokeping folder at /opt first
then copy the thirdparty folder into it

# mkdir /opt/smokeping
# cp -r thirdparty /opt/smokeping/

# ./configure --prefix=/opt/smokeping
# make install

~ NOTE ~
if you encounter problem, please try make install again
this is because for my situation when i first make install, it pop some error but when i try make install again, the error gone

Now you can go to /opt/smokeping/etc and prepare the config file

# cd /opt/smokeping/etc
# for foo in *.dist; do cp $foo `basename $foo .dist`; done

--------------------------------------------------------------------------------------------------------------

Now is time to prepare for the interface
make sure you had install apache
else please install it using yum install httpd

#vim /etc/httpd/conf/httpd.conf

change:
DirectoryIndex index.html index.html.var
to:
DirectoryIndex index.html index.html.var smokeping.fcgi

then enable this
AddHandler cgi-script .cgi

---------------------------------
# vim /etc/httpd/conf.d/smokeping.conf

<Directory "/var/www/html/smokeping">
    Options +ExecCGI
</Directory>
--------------------------------
# mkdir /opt/smokeping/img
# mkdir /opt/smokeping/data
# mkdir /opt/smokeping/var
# mkdir /opt/smokeping/cache
# chown -R apache:apache /opt/smokeping/img
# chown -R apache:apache /opt/smokeping/cache
# ln -s /opt/smokeping/htdocs /var/www/html/smokeping
# ln -s /opt/smokeping/img /var/www/html/smokeping
# ln -s /opt/smokeping/cache /var/www/html/smokeping


# chmod 600 /opt/smokeping/etc/smokeping_secrets
# chmod 600 /opt/smokeping/etc/smokeping_secrets.dist
# chown -R apache:apache /var/www/html/smokeping

Before we start smokeping, please edit your configuration first
edit the smokeping config to your need (change the part in Red color word
# vim /opt/smokeping/etc/config

For mine, i had turn off my firewalld as it was mean for private LAN
# systemctl stop firewalld

and i also had turn SeLinux
# setenforce 0

Start the apache service
# systemctl start httpd

start the smokeping services
# ./bin/smokeping --config=/opt/smokeping/etc/config --logfile=smoke.log

For startup script
you can get it from here
http://oss.oetiker.ch/smokeping/pub/contrib/smokeping-start-script
just edit the smokeping path
then put at /etc/init.d/
chmod 755 it


Thanks Will for pointing out the typo and mistake

  2. Good guide but couple of mistakes, and as you asked for corrections I'll oblige :)
    # mkdir /opt/smokeping/cache; command is missing from the instructions,
    # ln -s /opt/smokeping/cache /var/www/htnl/smokeping <- typo should be HTML,
    Worth mentioning that firewalld will need to be adjusted, I simply opted for,
    # systemctl disable firewalld; in a secure LAN ymmv

    Otherwise excellent - saved me a bunch of time!

  4. Thanks for the instructions.
    Most of the installation instructions I found require rpmforge, that is now dead or almost, so I was relieved to discover that EPEL can replace it, and I can continue to use SmokePing.

    In case anybody had the same problem, my system required a reboot after installation before I could start the service.

  7. I think you miss the most important command:
    mv /opt/smokeping/htdocs/smokeping.fcgi.dist /opt/smokeping/htdocs/smokeping.fcgi
    otherwise you will get the plain-text smokeping main website
