Prerequisites

Prerequisites for 25 concurrent users 1:

  • 2 CPU 2
  • 8GB RAM

Prerequisites for 200 competing users 1:

  • 8 CPU 2
  • 12GB RAM

32Go 6 >30 > 20000

Disk space:

  • 1 system disk of 15 GB which include / and swap partitions
  • 1 data disk of 50 GB whose volume depends mainly on the documents

Associated with the products, we can decompose the space used for 1,000 products as follows:

  • Database space: about 2 GB
  • Space for full text search index: about 2 GB
  • Space for related documents: 10 GB (1,000 products * 10 MB)
1. With these metrics, N concurrent users are considered 10xN occasional users.
2. 2 CPUs are equivalent to 1 dual-core

Software prerequisites

beCPG is distributed as a docker container allowing it to run on any server. beCPG provides automatic installation and full support for the installation of containers in the following environment Ubuntu Server >= 20.04.4 LTS 64 bits.3

Ubuntu Server 20.04 LTS 64 bits can be installed on a virtualized, dedicated or cloud server.

Download address for ISO images: [https://www.ubuntu.com/download/server]

3. beCPG can also be deployed on a kupernete environment like Amazon EKS, Google cloud or other. However, this will not be the subject of this documentation.

The rest of the documentation is based on the use of a Linux Ubuntu >= 20.04.4 LTS 64 bits virtual machine .

Prerequisite client item

A post able to run a modern browser such as Firefox, a PDF reader and a suite office.

  • 1 CPU
  • 1 GB of RAM
  • Temporary storage space when editing documents (space took by documents in edition)

Server installation

beCPG provides an installation script that can be used and adapted as needed.

chmod + x install_docker_ubuntu_3_2_3.sh
./install_docker_ubuntu_3_2_3.sh

Once executed, the following software components will be installed on the virtual machine:

The installation consists of docker images that are built and distributed by beCPG. Docker Compose is used to start downloading and updating these images.

On the host machine, under /opt/becpg-srv-instances , you will find the installation folder of beCPG. The important files are:

/opt/becpg-srv-instances/inst1/.env
/opt/becpg-srv-instances/inst1/README.md
/opt/becpg-srv-instances/inst1/docker-compose.override.yml
/opt/becpg-srv-instances/inst1/docker-compose.yml
/opt/becpg-srv-instances/inst1/purge-logs.sh
/opt/becpg-srv-instances/inst1/ssl/000-default.conf
/opt/becpg-srv-instances/inst1/taillogs.sh
/opt/becpg-srv-instances/inst1/reindex.sh
/opt/becpg-srv-instances/inst1/stats.sh

Partition

By default, beCPG creates a new partition on the data disk. This partition contains all the data of the application, the containers and the docker volumes.

The mount point is /mnt/becpg-data by default

Sample script to create the new data partition on disk /dev/sdb

mkdir /mnt/becpg-data
mkfs.ext4 /dev/sdb
echo "/dev/sdb/mnt/becpg-data ext4 rw, noatime, errors = remount-ro, x-systemd.automount, x-initrd.mount 0 1" >> /etc/fstab
mount -a

Deploy a new version of beCPG

The deployment of beCPG and its update is are done by docker-compose . The orders are as follows:

cd/opt/becpg-srv-instances/inst1
docker-compound pull
docker-compose up -d
