Iniciar o UWSGI via init.d script sai com o código de saída 1 e diz 'failed', mas os processos estão funcionando bem

Question

Antes disso ser sinalizado como duplicado, eu leio esta questão ; no entanto, adicionar logfile2 não alterou nada.

Atualmente, estou criando um contêiner docker que executa uma pilha Python com UWSGI, pois usei a instalação Debian padrão do uwsgi para os scripts init.d e instalei a versão mais recente sobre ela usando pip .

Sempre que eu inicio o serviço, ele exibe um erro informando que o script falhou ao iniciar, mas quando tento fazer uma solicitação ao servidor ( localhost:5000 ) ou tente ver se os processos estão sendo executados usando ps aux | grep -i uwsgi , o servidor é executado muito bem.

Exemplo do que quero dizer:

root@f16b3268a956:~# /etc/init.d/uwsgi start
[FAIL] Starting app server(s): uwsgi -> ! failed!

No entanto, se eu olhar para os processos em execução

root@f16b3268a956:~# ps aux | grep -i uwsgi
user       984  0.1  2.8 235284 57876 ?        S    14:15   0:00 /usr/local/bin/uwsgi --ini /usr/share/uwsgi/conf/default.ini --ini /etc/uwsgi/apps-enabled/portal.ini --daemonize /var/log/uwsgi/app/portal.log
user      1009  0.0  2.7 253204 57040 ?        S    14:15   0:00 /usr/local/bin/uwsgi --ini /usr/share/uwsgi/conf/default.ini --ini /etc/uwsgi/apps-enabled/portal.ini --daemonize /var/log/uwsgi/app/portal.log
root      1146  0.0  0.0  12860   976 pts/0    S+   14:24   0:00 grep -i uwsgi

Conteúdo da minha configuração do uwsgi:

[uwsgi]
http-socket = localhost:5000
http-websockets = true
chmod-socket=775
chdir = /home/user/
master = true
binary-path = /usr/local/bin/uwsgi
virtualenv = /home/user/portal
module = portal.server:app
uid = user
gid = user
processes = 1
gevent = 1000
logfile2 = /tmp/test.pid
logto = /var/log/uwsgi/app/portal.log

Olhando para o arquivo de log não mostra nada de estranho:

Alguém sabe como contornar isso?

    

Answer 1

Acabei resolvendo o problema baseando minha imagem fora da imagem docker a seguir que usa supervisord em vez de um processo init.d (sem systemctl).
