Change the HTTP default port
Clickhouse has HTTP Interface that is enabled by default on port 8123. To change the default port, use the extraConfig
option:
{
services.clickhouse."clickhouse-1" = {
enable = true;
extraConfig = {
http_port = 9050
};
};
}
{#initial-database}
Initial database schema
To load a database schema, you can use the initialDatabases
option:
{
services.clickhouse."clickhouse-1" = {
enable = true;
initialDatabases = [
{
name = "sample_db";
schemas = [ ./test.sql ];
}
# or just create the database:
{
name = "sample_db_without_schema";
}
];
};
}
