MySQLCluster

Nous allons mettre en place un cluster MySQL basé sur MySQL Cluster.

Mise en place du réseau

docker network create cluster --subnet=10.100.192.168.0.0/16

Puis récupérons leles dockerfichiers file:ou recopier les fichier de configuration:

git clone https://github.com/mysql/mysql-docker.gitdocker/tree/mysql-cluster

Le fichier my.cnf est ainsi:

[ndbd default]
NoOfReplicas=2
DataMemory=80M
IndexMemory=18M


[ndb_mgmd]
NodeId=1
hostname=192.168.0.2
datadir=/var/lib/mysql

[ndbd]
NodeId=2
hostname=192.168.0.3
datadir=/var/lib/mysql

[ndbd]
NodeId=3
hostname=192.168.0.4
datadir=/var/lib/mysql

[mysqld]
NodeId=4
hostname=192.168.0.10

Lancement du noeud de management

docker run -d --net=cluster --name=management1 --ip=192.168.0.2 mysql/mysql-cluster ndb_mgmd

Puis lancons les noeud de données:

docker run -d --net=cluster --name=ndb1 --ip=192.168.0.3 mysql/mysql-cluster ndbd
docker run -d --net=cluster --name=ndb2 --ip=192.168.0.4 mysql/mysql-cluster ndbd

Et enfin on peux executer le noeud SQL:

docker run -d --net=cluster --name=mysql1 --ip=192.168.0.10 -e MYSQL_RANDOM_ROOT_PASSWORD=true mysql/mysql-cluster mysqld

 

Ce noeud va générer un password aléatoire :

docker logs mysql1 2>&1 | grep PASSWORD
[Entrypoint] GENERATED ROOT PASSWORD: =EbISQomAxvOmnam4d9EJigIjwA
