Install cacti 0.8.8b in redhat 7.0

[liuyouxi1]

Hi, Dear all

Recently I installed cacti 0.8.8b on redhat 7.0 following link "http://www.tecmint.com/install-cacti-ne ... ora-17-12/", but after installation, I got error message when I visit this cacti server from another host(running windows 2008R2) through link http://10.103.112.250/cacti, error information as following: "This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying)"
Below is some details:
1,When I visit http://10.103.112.250 I can see the Apache page, this means firewall and httpd are configured normal
2,Cacti.conf is as following
# On httpd 2.4, change "Require host localhost" to "Require all granted".
# On httpd 2.2, change "Allow from localhost" to "Allow from all".

Alias /cacti /usr/share/cacti

<Directory /usr/share/cacti/>
<IfModule mod_authz_core.c>
# httpd 2.4
Require all granted
</IfModule>
<IfModule !mod_authz_core.c>
# httpd 2.2
Order deny,allow
Deny from all
Allow from all
</IfModule>
</Directory>

<Directory /usr/share/cacti/install>

#SecRuleRemoveById 960010

</Directory>


# These sections marked "Require all denied" (or "Deny from all")
# should not be modified.
# These are in place in order to harden Cacti.
<Directory /usr/share/cacti/log>

4, db.php as following

/* make sure these values refect your actual database/host/user/password */
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "password";
$database_port = "3306";
$database_ssl = false;

/*
Edit this to point to the default URL of your Cacti install
ex: if your cacti install as at http://serverip/cacti/ this
would be set to /cacti/
*/
//$url_path = "/cacti/";

/* Default session name - Session name must contain alpha characters */
//$cacti_session_name = "Cacti";

?>

5 I can use cacti/password to access database

[root@vincent112250 ~]# mysql -u cacti -p

I will be appreciate if you can give me any clue or tell me where can I find the log of PHP, cacti, or httpd for further troubleshooting. Thanks a lot

Anyone can help ?? thanks a lot

Some clue as below, every time when I tried to login to this server, I can get the error information for /var/log/httpd/error_log

[Tue Jan 05 21:47:04.256044 2016] [:error] [pid 7490] [client 10.35.83.91:62906] PHP Parse error: syntax error, unexpected 'new' (T_NEW) in /usr/share/cacti/lib/adodb/adodb.inc.php on line 866

It's weird that I install the cacti by yum install, how this syntax error can happen ??? Is it a mis-match between the PHP version and cacti ??

The version are as following :

[root@vincent112250 cacti]# rpm -qa |grep php
php70w-cli-7.0.0-1.w7.x86_64
php70w-devel-7.0.0-1.w7.x86_64

php70w-process-7.0.0-1.w7.x86_64

Same issue after upgrading to php7.

[Wed Jan 27 06:10:08.593413 2016] [:error] [pid 9983] [client 10.100.0.10:58039] PHP Parse error: syntax error, unexpected 'new' (T_NEW) in /public/www/cacti/lib/adodb/adodb.inc.php on line 866

8.8b on my end too. Were there some adjustments that would make 8.8f function in php7?

Nope, even with 8.8.g its busted.
PHP Parse error: syntax error, unexpected 'new' (T_NEW) in /srv/http/cacti/lib/adodb/adodb.inc.php on line 866
Bad code in /lib/adodb/adodb.inc.php

http://php.net/manual/en/reserved.keywords.php

"new" souldn't be used for functions. Anyone know a quick and dirty fix? or is there a planned fix? PHP7 support would be nice.

[phalek]

You could try updating adodb to the latest version. 0.8.8f comes with 4.54, current adodb is 5.2: http://adodb.sourceforge.net/#docs

Not sure though what issues this may create

[jayray]

I scrapped the whole idea and started a new topic that was more specific. I've been way down the rabbit hole on this one, running the latest git and fighting session issues.. Thanks for the input, the adodb was definitely causing errors on my old install.

[phalek]

Hi jayray,

Can you edit the topic then with a "Closed" and add the link to the new topic ?

[jayray]

I would, but it was originally liuyouxi1's topic. I hijacked it because I was having the same issues.

[phalek]

Ups Then maybe he can look into the ADODB stuff
