Starting /stopping nginx


#1

hey Guys,

Anyone else notice that in the resent *.52 release stopping/starting
nginx does not restart the process? I manually have to kill -9 the
master and each child…

any ideas? it gets annoying when you have to do updates :slight_smile:
Thanks,
Payam


#2

What’s your distro? Have you tried its mailling-lists?

HTH,

BTW, why do you use stop/start instead of graceful reload ?


#5

Hey,

I noticed that the graceful reload was not actually loading the new
config changes and so ive had to use a hard down/start

kill -quit $master works

i did also notice that nginx will not start with the following in the
config:
pid /var/log/nginx/nginx/pid;

so ive had to remove the line from the config…
so it makes sense to why i cant stop it… the pid is not able to write
to a file

I never saw this. Anyway, nginx should write the reason in error_log.

kill -quit $master works

i did also notice that nginx will not start with the following in the config:
pid /var/log/nginx/nginx/pid;

Also, nginx should write the reason in error_log.

I use -QUIT only for in this sequence:

kill -USR2 cat nginx.pid # upgrade
kill -QUIT cat nginx.pid.oldbin

I use only -HUP to reload configuration

whats your start/stop script look like?

I installed 0.7.52 on several Virtuozzo containers. All are running CentOS, some 32 bit and some 64. After reading your post I checked them all. One (and only one) is having a similar issue. It’s a 64 bit container. All of the others are fine and all use an identical init script.

Do you able to stop/reload nginx by head:

kill -QUIT cat /path/to/nginx.pid

?


#9

wow i feel like a dumb dumb… re-reading what i had wrote out in the
config … i noticed i had typed in /var/log(s)/nginx… where its
/var/log/nginx…

sorry for the dumb problem guys… i thought i was going crazy and yet
it was such a stupid mistake

on a side note, anyone have a sample config of allowing proxy_pass to
attach $realip of the client to the backend origin server? My origin
sees all connections being made by my nginx proxy even though i have
x-forward set in my proxy.conf

proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffers 32 4k;

Thanks everyone for their help…

The problem sorted itself out after I (just) rebooted the container.

So I am no longer having this problem. :slight_smile:

I used to use the start-stop daemon but switched all servers to this as
I have upgraded nginx versions:

nginx - this script starts and stops the nginx daemon
