Installation problem

(Arethusa) #1

Hello, Merry Christmas ^^

Today, I tried on my own server to install: icinga2, icingaweb2, mariadb, influxdb on Centos7

In first time, I have split services, but I have an error, so I try a basic all in one installation, but I have the same problems, I can’t finish the IcingaWeb2 Installation!

So, let me be more precis:

icinga2 version: r2.10.2-1)
Icingaweb2 version: 2.6.2-1.el7
php: php71

Now my history of install

yum update -y
yum install epel-release -y
yum install httpd -y
yum install mariadb mariadb-server -y
yum install
yum install epel-release -y
yum install
yum install centos-release-scl
yum install icingaweb2 icingacli
yum install icinga2-ido-mysql -y
yum install icinga2 -y
yum install nagios-plugins-all -y

For mariadb, I do the simplest configuration:

[root@supervision ~]# mysql -u root -p
Enter password:

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> EXIT;


[root@supervision ~]# mysql -u root -p icinga < /usr/share/icinga2-ido-mysql/schema/mysql.sql

I configure idomysql

[root@supervision ~]# cat /etc/icinga2/features-enabled/ido-mysql.conf
 * The IdoMysqlConnection type implements MySQL support
 * for DB IDO.

object IdoMysqlConnection "ido-mysql" {
  user = "icinga"
  password = "icinga"
  host = "localhost"
  database = "icinga"

And of course: it’s enabled:

[root@supervision ~]# icinga2 feature list | grep Enabled
Enabled features: checker command ido-mysql influxdb mainlog notification 

So now the problems:

Why I have conflict? I never see this message before.

That say "successful, but “there is currently no instance writing to the IDO” Of course, it’s not finish!

I don’t understand the problem, maybe I will try with oldest version.

Thank you, have a good holiday!


As shown in the first orange message block it is highly recommended not to mix database schemas of Icinga and IcingaWeb (which you seem to have done as the database name for icingaweb_db is ‘icinga’).

Thank you for answer.

I had username problem with my database on MariaDB. That was my fault.

Thank you.

Hello, I have had issues like this countless number of times building icinga2 web.
Your Database Name for Icinga and Icingaweb2 are the same, so you have to innovate here.

For icinga Database Name = icinga_db
For icingaweb2 Database Name = icingaweb_db

That should work, ‘cause the names you have now are conflicting. Let me know how it goes. Happy icinga!
