Initial data

Table 1. Recommended hardware solutions

Table 2. Example of drafting hardware requirements

After determining the requirements of the project, create a preliminary network map.

Table 3. An example of components allocation in the address space for a single node

Connecting to network

The topology of connecting the server to the network to ensure redundancy is recommended to be done using 2 switches.

...

Server network interfaces are also included in pairs in switches, on which port aggregation (port-channel) is configured in LACP mode. For example, eth0 and eth1 are included to first switch (port-channel 1), and eth2 and eth3 — to the second (port-channel 2).

Configuring network

Install the software switch according to the parameters specified in the technical specification. In this example, it is assumed that the required operating system is already installed. 

...

A single address for accessing the MySQL database is defined for all cluster nodes, for example, the ecss-mysql address 127.0.0.1. Thus, the uniformity condition is fulfilled, in which all cluster nodes have completely identical data about the current state of the dynamic components of the software switch (for example, call history).

Preparing system network interfaces

According to the technical specification, the system has 4 network interfaces. Information about their status can be viewed using the ifconfig or ip a command:

First, the network interfaces are configured. Ubuntu18 uses the netplan utility to configure.

...

Example of configuring ecss-netplan.yaml file for active-backup connection option:

# Netplan for the ecss1 host of the test software switch
# Pay attention to the mandatory presence of at least two spaces in each line and section (except for the network section line)

network:
  version: 2 # netplan version
  renderer: networkd # netplan configuration executor
  ethernets: # Ethernet interfaces description section
    eth0: # Interface name
      dhcp4: no # Disabling dynamic distribution of IP address on the interfaces
    eth1:
      dhcp4: no
    eth2:
      dhcp4: no
    eth3:
      dhcp4: no

      addresses: [10.0.3.237/24]

Apply parameters with the command:

sudo netplan apply

Operating system software update

...

sudo apt update
sudo apt upgrade

Software installation and configuration

Install all the proposed packages:

sudo apt install aptitude atop ethtool htop iotop mc minicom mtr-tiny nmap pptpd pv screen ssh tftpd vim sngrep tshark cpanminus gnuplot libgraph-easy-perl debconf-utils

Installing ecss-mysql package

The installation begins with the deployment of the MySQL server and the integration of the ecss-mysql database.

To install, run the command:

sudo apt install ecss-mysql

Configuring ecss-dns-env package

Before installing the ecss-mysql package, you will be prompted to configure environment variables for services in dnsmasq. Configuration manager will prompt to select the sections to configure, do not select anything.

Configuring ecss-mysql package

When installing the package, the following data will be requested:

Changing the default path — agree to change the configuration file to enter the path to the ecss-mysql databases by entering "Y".

MySQL databases used by the ECSS-10 system will be stored under the path /var/lib/ecss-mysql after installation. Check for files in the folder:

ls -l /var/lib/ecss-mysql/
total 36

drwxr-xr-x 2 mysql mysql 4096 Sep 26 14:32 web_conf

Check that the server is running:

sudo systemctl status mysql

Installing the ecss-node package

Installing the ecss-node package:

...

During the package installation ssw user is created, on whose behalf all ecss services are launched*. The necessary directories are being created, DNS is being configured, SSL certificates are being configured. During the installation, 8 questions necessary for the formation of configuration files will be asked.

To generate certificates, select manual method. All questions can be answered as suggested by default.
