Hi,
I am using nginx 1.8.0 as a load balancer.
Below is the configuration snippet:
upstream appservers {
least_conn;
server 10.21.3.123:8083;
server 10.21.3.125:8083;
}
server {
listen 443 ssl spdy backlog=2048;
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains";
add_header Alternate-Protocol 443:npn-spdy/3;
ssl_certificate
/etc/nginx/click.rummycircle.com/click.rummycircle.com.crt;
ssl_certificate_key
/etc/nginx/click.rummycircle.com/click.rummycircle.com.key;
ssl_ciphers
ECDHE-RSA-AES256-SHA384:AES256-SHA256:AES256-SHA256:RC4:HIGH:!MD5:!SSLv2:!ADH:!aNULL:!eNULL:!NULL:!DH:!ADH:!EDH:!AESGCM;
ssl_prefer_server_ciphers on;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
location / {
# log_format postdata '$remote_addr - $remote_user
[$time_local] '
# '"$request" $status $bytes_sent '
# '"$http_referer" "$http_user_agent"
"$request_body"';
# access_log /home/deploy/nginx_logs/new_access.log
postdata;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For
$proxy_add_x_forwarded_for;
proxy_pass http://appservers;
}
}
Nginx is balancing the load between our 2 servers: 10.21.3.123 and
10.21.3.125. I want to remove one server from the load balancer at runtime
without any packet loss. So I removed i by changing the configuration like
below:
upstream appservers {
least_conn;
server 10.21.3.123:8083;
}
Then I reloaded nginx: sudo service nginx reload
I checked with nginx -t that Nginx successfully reloaded.
However, it still continues to send new requests to the removed server.
Please assist.
