problem with running cmd.php

khutton · Posted: Thu Dec 12, 2002 11:50 am Post subject: problem with running cmd.php

I have compiled php into apache and created the binary but when I run cmd.php (from command line) I get the following error

ping: bad number of packets to transmit.
sh: mysqladmin: command not found
sh: /usr/bin/smbstatus: No such file or directory
wc: /var/log/httpd/access_log: No such file or directory
X-Powered-By: PHP/4.2.3
Content-type: text/html

This error is also logged in my mail by crontab when it runs cmd.php every five minutes

The no such file or director errors are simple enought to fix but I don't understand the ping and mysqladmin error. I have mysqladmin, but don't know where to go to change where cacti thinks it is. I have it in /usr/local/mysql/bin.

I have my complete process for installing cacti. I am trying to write detailed instructions for others. I will post them after I post this question for any ones review.

Thanks in advance for any help. If you want the directions that I have so far look at next post or email/message me.

Here is the directions I have so far. If any one sees any glaring edits I would appreciate some help. If I can get this to work I will have a very well documented set of directions. Which should help this application and message board. Thanks again for your help

Just a note, this is all done on a fresh install of RedHat 7.3, standard server install with the gnome package selected. Everything else is basic.

Start instructions:
Download the Following:

Cacti-0.6.8a.tar.gz
MySQL-3.23.54-pc-linux-gnu-i686.tar.gz
php-4.2.3.tar.gz
rrdtool-1.0.35.tar.gz
apache_1.3.27.tar.gz
ucd-snmp-4.2.3.tar.gz (you may not need this if you have snmpget and snmpwalk already on you machine)

Copy all of these to /usr/local/cactisetup

********************************************************************

Installing Apache
from /usr/local/cactisetup
tar zxvf apache_1.3.27.tar.gz (unpacking apache)
mv apache_1.3.27 apache (renaming the apache directory to apache)
cd apache
./configure --prefix=/www --enable-module=so
make
make install
cd ..

********************************************************************

Installing PHP
cd /usr/local/cactisetup
tar zxvf php-4.2.3.tar.gz (unpacking php)
mv php-4.2.3 php4 (renaming the php directory to php4)
cd php4
./configure --with-mysql --with-apxs=/www/bin/apxs
make
make install

Copy and Edit php.ini
cp php.ini-dist /usr/local/lib/php.ini
cd /usr/local/lib
pico php.ini
change Register_Globals=On and Register_argc_argv=On
save edits

Now to create the php command line application
cd /usr/local/cactisetup/php4
./configure --with-mysql
make
make install
php binary should be in /usr/local/cactisetup/php4/

*********************************************************************

Edit httpd.conf
cd /www/conf
pico httpd.conf
edit your servername to reflect proper name and add this line
AddType application/x-httpd-php .php
LoadModule php4_module libexec/libphp4.so
save edits

*******************************************************************

Start web server
cd /www/bin
./apachectl start

test your webserver

You should get the Apache default page if all is well. If you do not please refer to the Apache

documentation for any errors. If you have installed Gnome on you Linux installation then you should have

a GUI configuration utility for Apache. Please run this and you should be able to configure everything

you need to get your server running. Doing this will overwrite any changes made to httpd.conf by hand.

I suggest you edit it by hand. The documentation is very good.

***********************************************************************

Starting Apache at boot
cd /etc
pico rc.local
add the line
/www/bin/apachectl start &
save changes

********************************************************************

Unpacking Cacti
tar zxvf Cacti-0.6.8a.tar.gz (unpack cacti)
mv cacti-0.6.8a /www/htdocs/cacti (rename and move cacti-0.6.8a to /www/htdocs/cacti)
cd /www/htdocs
chown -R nobody:nobody /www/htdocs/cacti (this allows the webserver to show your cacti dir)

********************************************************************

Unpacking rrdtool
tar zxvf rrdtool-1.0.35.tar.gz
mv rrdtool-1.0.35 rrdtool

Setting up rrdtool
cd /usr/local/cactisetup/rrdtool
./configure
make
make install

rrdtool will be installed to /usr/local/rrdtool-version#

*******************************************************************

Unpacking MySQL
tar zxvf mysql-3.23.54-pc-linux-gny-i686.tar.gz (unpack mysql)
mv mysql-3.23.54-pc-linux-gnu-i686 /usr/local/mysql (rename and move the mysql directory to mysql)

Setting up mysql
groupadd mysql
useradd -g mysql mysql (this is the user that will run MySQL)
cd /usr/local/mysql
scripts/mysql_install_db
chown -R root .
chown -R mysql data
chgrp -R mysql .
./bin/safe_mysqld --user=mysql &
./mysql -u root mysql
mysql> SET PASSWORD FOR root@localhost=PASSWORD('newpassword'); (sets password for root mysql user not

root linux user, like sa account on other DB's)
exit

To start the server at boot time add this line to /etc/rc.local

/bin/sh -c 'cd /usr/local/mysql ; ./bin/safe_mysqld --user=mysql &'

Reboot machine to test the installation of mysql
once the server has rebooted

cd /usr/local/mysql/bin
./mysqladmin --user=root -pnewpassword version

if you get the version screen from mysql, the server started at boot

*************************************************************************

installing Cacti tables in mysql
from /usr/local/mysql/bin/
./mysqladmin --user=root -pnewpassword create cacti
./mysql -u root -pnewpassword cacti < /www/htdocs/cacti/cacti.sql

Create a MySQL username and password for Cacti
./mysql --user=root -ppassword
GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'somepassword';
flush privileges;
exit

Edit /www/htdocs/cacti/include/config.php

database_default = "cacti";
database_hostname = "localhost";
database_username = "cactiuser";
database_password = "somepassword";

cd /etc
pico crontab
add this line
*/5 * * * * * cactiuser /usr/local/cactisetup/php4/php /www/htdocs/cacti/cmd.php > /dev/null 2>&1

Check and make sure that your cacti user has permissions/is the owner of to the /path-to-cacti/cacti/rra and /path-to-cacti/cacti/log directories.

Hi,
I use RH7.2/cacti 06.8a
I applied khutton's instruction. After that, i saw graphics' bacground but there's no trend line in my pages.
First og all, ı want to describe what i did:
1. I applied khutton's instruction about linux.
2. I created a user in linux as cactiuser
3. I use chown cactiuser rra/ log/ command in ../htdocs/cacti/ directory.
4. i log on as root everytime
5. I edited /etc/crontab as:

If you are seeing the graph but no lines it could be that the rrd files are not being created in the cacti/rra/. Are there any files in the cacti/rra/ that correspond to your snmp devices?

As long as cactiuser has the proper rights to all the necessary directories.
