nfs share file configuration

on file share server

• install nfs

$ sudo apt-get install -y nfs-kernel-server

• create directory for file sharing

$ mkdir -p /home/cnoc/share
$ sudo mkdir -p /export/cnoc
$ sudo chown cnoc:cnoc /export/cnoc

• bind mount filesystem edit file /etc/fstab

$ sudo vim /etc/fstab

add line end of file like

UUID=702da501-ff9a-11e9-a6a6-506b8dc215cd / ext4 defaults 0 0
UUID=702da500-ff9a-11e9-a6a6-506b8dc215cd /boot ext4 defaults 0 0
/swap.img       none    swap    sw      0       0
/home/cnoc/share /export/cnoc none bind 0 0

mount filesystem

$ sudo mount -a

• export fs configuration

$ sudo vim /etc/exports

add line end of file like this allow canvas lms use nfs exports if add canvas-lms server you have to add new server ip address here

/export/cnoc 10.110.60.215(rw,sync,no_root_squash,no_subtree_check)
/export/cnoc 10.110.60.144(rw,sync,no_root_squash,no_subtree_check)

restart nfs service

$ sudo service nfs-kernel-server restart

postgres database deployment

on postgres server

• create dokcer-compose.yml for deploy postgres database

$ mkdir postgres
$ cd postgres
$ vim docker-compose.yml

add line in docker-compose.yml like

version: '3'
services:
        pg:
                image: postgres:12.3
                container_name: postgres
                restart: always
                environment:
                        POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
                        POSTGRES_DB: ${POSTGRES_DB}
                volumes:
                        - ./data:/var/lib/postgresql/data
                ports:
                        - 5432:5432
        adminer:
                image: adminer
                restart: always
                ports:
                        - 8080:8080

• create .env file for environment variables use in container

$ vim .env

add line in .env file like

POSTGRES_PASSWORD=<your password>
POSTGRES_DB=canvas

• deploy postgres

$ docker-compose up -d

redis cache deployment

on file share server

• create docker-compose.yml for deploy redis

$ mkdir redis
$ cd redis
$ vim docker-compose.yml

add line in docker-compose.yml like

version: '3'
services:
        redis:
                container_name: redis
                image: redis:6.0.4
                ports:
                        - 6379:6379
                restart: always

• deploy redis

$ docker-compose up -d
