Não é possível iniciar o postgresql

Question

Sempre que tentar iniciar postgresql , no entanto, falhará. Estou executando o Kali NetHunter.

Aqui está minha saída de terminal

root@kali:~# service postgresql start

Answer 1

postgresql não está ativo porque não pode criar um segmento de memória compartilhada grande o suficiente, conforme visto pelo erro:

could not create shared memory segment: Function not implemented
Failed system call was shmget

Para corrigir isso, faça:

sudo sysctl -w kernel.shmmax=134217728

Para defini-lo permanentemente após as reinicializações, edite /etc/sysctl.conf e anexe a ele o kernel.shmmax = 134217728 :

sudo vi /etc/sysctl.conf
kernel.shmmax = 134217728

ATUALIZAÇÃO para a resposta:

Depurando com a ajuda do OP:

sudo sysctl -w kernel.shmmax=134217728 sysctl: cannot stat /proc/sys/kernel/shmmax: No such file or directory

Isso uniu que o Kali NetHunter é para dispositivos Android, a resposta mais correta e definitiva é que shmem support não foi compilado nesta versão do kernel.

Isso também limita a impossibilidade de executar outro software que tenha shmem como Apache .

Infelizmente, também pode não fazer muito sentido executar um banco de dados postgresql em dispositivos Android de classe.

No entanto, um possível curso de ação é tentar encontrar outro pacote do kernel (se houver), que suporta shmem, ou no limite de compilação cruzada de um kernel. Obviamente, você não deve considerar esta rota é o seu dispositivo é muito baixo em disco e / ou memória.
