RPM package installation

This guide will lead you through the installation of the ApiOmat .rpm package. The package is supported for the OS versions defined in Infrastructure Requirements.

Installing MongoDB

ApiOmat is based on MongoDb database. MongoDB can be also installed via yum:

Installing ApiOmat

Preparation for installing

Make sure that php_mcrypt is installable or alreay installed (http://stackoverflow.com/questions/17109818/install-php-mcrypt-on-centos-6) for dashboard

Installation from Yum repository

If your installation machine has internet access, add the ApiOmat Yum repository to /etc/yum.repos.d/apiomat.repo ( replace <USERNAME>:<PASSWORD> with the credentials provided via email):

[apiomat]
name=apiOmat
baseurl=https://<USERNAME>:<PASSWORD>@repo.apiomat.com/yambas/rest/web/Repo/LIVE/rpm
gpgcheck=0
enabled=1

Add php7 repository - if you want to use php5 you have to use the apiomat-dashboard.php5 package. When using php5 package you also don't need to remove old php packages and add other repositories.

# if php5 is already installed and you want to use php7 just remove old version of php to avoid conflicts
sudo yum remove php*
#add repos
sudo rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
sudo rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
sudo yum update
#add repos
sudo rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
sudo rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm
sudo yum update

Now run

sudo yum update
sudo yum --nogpgcheck install apiomat-yambas
sudo yum --nogpgcheck install apiomat-dashboard

Installation with rpm files

If you obtained the installation files manually, copy the .rpm packages of YAMBAS and Dashboard to the application server(s) and enter:

sudo yum localinstall apiomat-yambas-xxxx.rpm
sudo yum localinstall apiomat-dashboard-xxx.rpm
#or
sudo yum localinstall apiomat-dashboard.php5-xxx.rpm

After Dashboard installation, you will be asked to open http://localhost/dashboard/install in your browser. Follow the steps in this installer tool to configure ApiOmat automatically.

Reboot afterwards to start all services automatically

Next steps

Installing Monitoring Service (optional)

ApiOmat microservices require a Java 8 runtime to be installed. If Java 8 was not installed before (YAMBAS includes an installation) it has to be installed manually: AdoptOpenJDK Installation

ApiOmat is able to monitor server data like CPU load or disk space. To enable this feature, a central service registry has to be installed on one node in the cluster:

sudo yum --nogpgcheck install apiomat-serviceregistry

Additionally, a monitoring service has to be installed on each node (app and database) which should be monitored:

sudo yum --nogpgcheck install apiomat-monitoringservice

By default, the services are not added to any runlevel. To automatically start the services after reboot, execute the following commands:

sudo chkconfig --level 345 apiomat-serviceregistry
sudo chkconfig --level 345 apiomat-monitoring

In the next step, you have to check the Java version: Oracle Java 8 is required (do not use OpenJDK).

Finally, start the services and make sure the service registry is fully started (http://localhost:8761/ is reachable) before you start the monitoring service:

sudo /etc/init.d/apiomat-serviceregistry start
sudo /etc/init.d/apiomat-monitoringservice start
