[megoldva] Nginx LXC konténerben nem indul el, mint szerviz, de manuálisan elindítva fut megfelelően

Az nginx LXC-ben nem indul el, mint szerviz, de manuálisan elindítva fut CentOS 7-en.

systemctl status nginx.service -l

Oct 01 22:10:27 nginx.teszt systemd[1]: PID file /run/nginx.pid not readable (yet?) after start.

/etc/nginx/nginx.conf tartalma:

user nginx;
worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

events {
worker_connections 128;
}

http {
include /etc/nginx/mime.types;
default_type application/octet-stream;

log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

access_log /var/log/nginx/access.log main;

sendfile on;
#tcp_nopush on;

keepalive_timeout 65;

#gzip on;

include /etc/nginx/conf.d/*.conf;
}

Honnan veszi a systemd, hogy a PID a /run/nginx.pid -ben van?
Pedig a conf-ban helyesen a /var/run/nginx.pid szerepel.

nginx

után szépen fut:

ps ax|grep nginx
2383 ? Ss 0:00 nginx: master process nginx
2384 ? S 0:00 nginx: worker process

De nem tudom systemctl -en keresztül kezelni.

Ez alapján raktam fel:

https://www.digitalocean.com/community/tutorials/how-to-install-nginx-o…

De már itt sem működött a konténerben:

systemctl start nginx.service

Mit nem veszek észre?

UPDATE 1:

/usr/lib/systemd/system/nginx.service állományban hibás az alap beállítás, át kell írni a PID-et...
