Two problems with CACTI installation on Fedora 27 server

[icomaznev]

Hello,
I am using Fedora 27 server in my office and I decided to install CACTI.
The version of HTTP server is:
# httpd -v
Server version: Apache/2.4.29 (Fedora)
Server built: Oct 25 2017 12:34:45
The version ov PHP is:
# php -v
PHP 7.1.15 (cli) (built: Feb 28 2018 11:19:18) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies

All required php modules are installed. In the PHP.ini file the date time is set to date.timezone = 'Europe/Sofia' (btw I tried with ', with ", without them /with apostroff, with quotation marks and without them/).
In the same time when I tried to do an initiall installation of the cacti (via web interface), I am getting next errors:
PHP Timezone Support
ERROR: Your Web Servers PHP Timezone settings have not been set. Please edit php.ini and uncomment the 'date.timezone' setting and set it to the Web Servers Timezone per the PHP installation instructions prior to installing Cacti.
Required PHP Modules

About the first error:
If I try the next commands I am getting:
# date
Tue Mar 27 15:20:29 EEST 2018
#php -r "echo date('r').PHP_EOL;"
Tue, 27 Mar 2018 15:20:47 +0300 ---- it supposed to be +0200

About the modules:
If I try to install them I'm gettring:
]# dnf install php-xml php-posix php-mbstring php-gd
Last metadata expiration check: 0:26:01 ago on Tue 27 Mar 2018 03:15:28 PM EEST.

Dependencies resolved.
Nothing to do.
Complete!

Please help. There is obviously something wrong, but I cannot find out wht it is.

I have recently done a Fedora 27 installation so I know it's possible and it should be fairly straight forward. I have notes on my wiki page from my test environment. Please note, my test setups always create three sites so when reading the instructions over be prepared to adjust according to your single installation.

[nilsvandermark]

I just finished a Fedora 27 installation.

It should install every dependency with ''dnf install cacti'.

My php.ini says and works:
[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = Europe/Amsterdam

Maybe you should do without quotation marks!

Try uninstall the dependencies and reïnstalling.
You could also try to reïnstall cacti.

Hello nilsvandermark.
Thank you for the replay.

I took a look at the configurations you have post to your wiki.
I think I have everything this in my configuration (keeping in mind that mine is for a single site).
What I do not have is the SSL configurations, but so far I think I do not neet them.

I do not get the meaning of:
Configuration MySQL
Enable custom configurations - " > /etc/my.cnf.d/cacti.cnf. Could you explain me what this means and where you put this?
Everythin else I have written (with the difference that except default_time_zone='+00:00' I have default_time_zone='+02:00'.

But I thing this is not a problem. The problem could be that the time in the base sistem, http and the database are absolutely equal, but if I ask for the time zone it sais +03:00, doesn't matter that I am setting default_time_zone='+02:00' and date.timezone = 'Europe/Sofia".

And of course another problem is that cacti doesn't recognize the installed PHP modules and in the same time it sais that those modules are required.

If you can give me some other advises I really will appresiate this.

Thanks again.

P.S. And as I said I tried date.timezone = 'Europe/Sofia', date.timezone = "Europe/Sofia", date.timezone = Europe/Sofia.
It doesn't issue any error and if I change Sofia with the city in different time zone (for example 'UTC' - it changes the time in PHP. So for me this works, but for cacti obviously doesn't.

[netniV]

OK, so with PHP there is a difference between the command line and apache. Apache has it's own PHP configuration. Starting with PHP 5.4, PHP no longer relies on the OS to tell it what timezone it's in, you have to do that.

I would create a PHP file in the cacti directory called date_test.php, then put the following code in it:

Code: Select all

echo "<pre>\n";
echo "Timezone: ". date_default_timezone_get() . "\n";
echo "INI Path:" . php_ini_loaded_file() . "\n";
$scanned = php_ini_scanned_files();
$files = explode(",",$scanned);
foreach ($files as $file) {
    echo '+ ' . str_replace("\n","",$file) . "\n";
}
echo "\n</pre>\n";

You should then be able to run this via CLI using php date_test.php and via a web browser going to http://<cacti_url>/date_test.php

This will show the PHP files used by each system. Make sure the datetime/zone information has been set for each set of files (normally in the php.ini file itself).

[icomaznev]

Dear netniV,
I did what you suddested. But if I tried to view the page http://ServerIPAddress/cacti/data_test.php I am getting just the text of the script in my browser.
Please advise how to execute the scrip in CLI?

There is another effect (defect) which appears. During my test (I was on the initial Install page of Cacti in my browser) the electricity company suddenly terminate my power current. So obviously the server was shutted down unexpetedly. Afre that I cannot view anything going to http://ServerIPAddress/cacti/ or to http://ServerIPAddress/cacti/install.
I checked - all necessary files (index.php) are in /usr/share/cacti and in /usr/share/cacti/install. In the browser I'm getting HTTP error 500 (the page isn't working; the server is currently unable to handle this request). In the very same time in the /var/log/http/error.log ... there is nothing, not even single record of my attempt to access the page. In the access log I can see that the browser tries to access the page and it is not restricted.
Very strange.
Please advise.

[icomaznev]

So fast update:
If I try to run the script from the CLI by using php -f data_test.php, I am getting:

Should I reinstall PHP?

And just to be more clear - if I run:

OK, this makes it seem like you don't have PHP installed properly. How did you install PHP?

[icomaznev]

#dnf -y install php php-xml php-session php-sockets php-ldap php-gd php-gmp

#systemctl start httpd
#systemctl start snmpd
#systemctl start mariadb

#dnf -y install cacti

BTW I uninstall php php-xml php-session php-sockets php-ldap php-gd php-gmp
#dnf -y remove php php-xml php-session php-sockets php-ldap php-gd php-gmp
and cacti
#dnf -y remove cacti

Installed them again.
Now I do not get the errors like
PHP Warning: PHP Startup: Unable to load dynamic library '/etc/php.d/bz2.so' - /etc/php.d/bz2.so: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library '/etc/php.d/calendar.so' - /etc/php.d/calendar.so: cannot open shared object file: No such file or directory in Unknown on line 0
But again I cannot view tha install page of Cacti
And when I try to start the provided script I got nothing (neither if I start it from the CLI or try to see it in the browser) but text of the script.
]# php -f data_test.php
echo "<pre>\n";
echo "Timezone: ". date_default_timezone_get() . "\n";
echo "INI Path:" . php_ini_loaded_file() . "\n";
$scanned = php_ini_scanned_files();
$files = explode(",",$scanned);
foreach ($files as $file) {
echo '+ ' . str_replace("\n","",$file) . "\n";
}
echo "\n</pre>\n";
This means for me that the PHP doesn't execute the script but just showing it.

[netniV]

I don't think you need the -f at the command line. Just php date_test.php will do it.

Does the browser now run php properly?

[icomaznev]

and now if I run:

# php -r "print phpinfo();" | grep ".ini"

I got:

And more from testing:

If I create a simple php script (data_test1.php) like:

<html>
<head><title></title></head>
<body>
<?php
//Inside the php block so it gets executed and prints 'Hello World'
echo "Hello, World!";
?>
<!--Outside the php block so it just gets echoed and prints 'echo "Hello, World!";' -->
echo "Hello, World!";
</body>
</html>

If I try to run the script from the CLI - again I get the script not executed, but just listed (I can see the plain text in the terminal window)

# php data_test1.php

the result is:

<html>
<head><title></title></head>
<body>
Hello, World! <!--Outside the php block so it just gets echoed and prints 'echo "Hello, World!";' -->
echo "Hello, World!";
</body>
</html>

But if I try to execute the script in the browser:

http://my server IP address/cacti/data_test1.php

In the browser result is :

Hello, World! echo "Hello, World!";

So I am confused

[icomaznev]

And again if I try to view in my browser:

http://192.168.20.199/cacti/index.php
or
http://192.168.20.199/cacti/install/index.php
or
http://192.168.20.199/cacti/install/index.php?step=0

I am getting:

This page isn’t working
192.168.20.199 is currently unable to handle this request.
HTTP ERROR 500

And again - no even single record in the /var/log/http/error.log
