[LFrederic]

Hi everyone,

I'm trying to install centreon-discovery on CES 3.3. Mariadb-devel is installed.
I followed this issue to resolve "MariaDB-devel FAIL"
--> https://github.com/Centreon-Community/centreon-discovery/issues/2

But now i got the following error :

`[root@vpc-gda-centreon centreon-discovery-master]# ./install.sh -i -t both
Waiting ...

Thanks for using Centreon

I found with "echo" flags that the script is trying to "install modPython;" on line 321. That's why i have a FAIL.

Do you have some advices to help me ?

Thank you.

Hi,

I finally managed to install this version on CES 3.3 by updating git and then git cloning centreon-discovery rather than downloading it :/

Hi
Can you explain what you do exactly?
on my Ces3.3 I have git 1.7.1
If I clone Git I have a local copie ok .
When I launch install.sh it's fail on Python Modules Mysqldb

Everything I did is here, I think I forget nothing :

Add MariaDB repository and update

echo "# MariaDB 5.5 CentOS repository list - created 2016-09-01 11:56 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1" > /etc/yum.repos.d/MariaDB.repo

yum update

Install requirements

yum groupinstall "Development tools"
yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel python-devel MariaDB-devel
rpm -vhU http://nmap.org/dist/nmap-7.12-1.x86_64.rpm

wget http://github.com/git/git/archive/v2.9.3.tar.gz
tar -xzf v2.9.3.tar.gz
cd git-2.9.3
make prefix=/usr/local all
make prefix=/usr/local install

Clone Centreon-Discovery

git clone http://github.com/Centreon-Community/centreon-discovery.git

Prepare before install

cd centreon-discovery
nano install.sh

replace line 210
PACKAGES="python-devel mysql-devel"
by
PACKAGES="python-devel MariaDB-devel"

chmod 755 install.sh

Install

./install.sh -i -t central

Then you should be able to install the module in Centreon Web administration.

... but it looks like discovering does not work anyway, still something missing :/

[fab-dub]

Got it !

First don't install last version of nmap, it won't work with it, if you did, do this :

rpm -e nmap
rpm -vhU https://nmap.org/dist/nmap-5.51-1.x86_64.rpm

Next, if you only have a central, you must install the module in "both" mode :
./install.sh -i -t both

Last, there is an error in the file /usr/share/centreon-discovery/DiscoveryAgent_central.py somewhere in here line 69:

if ligne.lstrip().startswith("$conf_centreon['password']"):
         conf_password = ligne.replace("$conf_centreon['password'] = \"","").replace("\";","").rstrip()

so it does not find the database password.
As I am really new to all this, I don't know how to fix this in a clean way, my temporary fix is on line 74 :
db=MySQLdb.connect(host=conf_host,user=conf_user,passwd='actual_db_passwd_here',db=conf_db)

I guess someone can provide a cleaner fix :)

[fab-dub]

best fix I can find :
nano /etc/centreon/centreon.conf.php

replace line 22
$conf_centreon['password'] = 'your_db_password';
by
$conf_centreon['password'] = "your_db_password";
