segmentation fault on ubuntu 16.04 LTS

[cherouvim]

Hello

On a vanilla ubuntu 16.04LTS which I just got from http://releases.ubuntu.com/16.04/ I do apt-get install cacti.

After I install (I get an "empty mysql port" warning during configuration by dbconfig-common, which I ignore) running cacti via apache or using its CLI scripts, gives me a segmentation fault. The dmesg output is:

Code: Select all

[ 1050.601708] php[14916]: segfault at 7ffc283ebff8 ip 000055ae36814f06 sp 00007ffc283ec000 error 6 in php7.0[55ae365f4000+3a8000]

I even downgraded php from 7 to 5.6 and still got segfault:

Code: Select all

[  773.887110] add_device.php[16973]: segfault at 7ffd2bd0ffa8 ip 000055a69e9859c8 sp 00007ffd2bd0ffa0 error 6 in php5.6[55a69e792000+3b7000]

Where should I look at to solve this?

Note that I pinpointed the php line which causes this. It's /usr/share/cacti/site/include/plugins.php:32

Code: Select all

$oldplugins = read_config_option('oldplugins');

thanks

Having the exact same issue, hoping for an answer.

Can you try Php 5.4 ?

I get it:

1. Replace $database_port="" with $database_port="3306" (or whatever you want) in /etc/cacti/debian.php
2. Replace dbc_dbport='' with dbc_dbport='3306' (or whatever you want) in /etc/dbconfig-common/cacti.conf

After this, you get other errors (like me about status_fail_date). You can correct them this way:

3. Edit file /usr/share/cacti/conf_templates/cacti.sql and replace "0000-00-00" with "2016-05-11" (i.e.). REPLACE ALL entries you find!!!.

At last, retry installation.

To fix error about status_fail_date do this:
remove NO_ZERO_IN_DATE,NO_ZERO_DATE from database mode
mysql -u root -p
Enter password:
