Hi:
I've found 2 kinds of 502 errors in my server:
connection reset by peer, it happens as request_time reach to 10s.
connection timeout, it happens as request_time reach to 3s.
Server is:
centos , kernel(2.6.32)
php5.2 php-fpm
nginx 1.6.3.
access logs outputs:
[28/Nov/2015:14:41:08 +0800] "GET /ben2.php HTTP/1.1" 502 172 "-"
"Apache-HttpClient/4.2.6 (java 1.5)" "-" 3.000
[28/Nov/2015:14:41:11 +0800] "GET /ben2.php HTTP/1.1" 502 172 "-"
"Apache-HttpClient/4.2.6 (java 1.5)" "-" 10.000
error logs:
2015/11/28 14:41:11 [error] 12981#0: *798323 recv() failed (104: Connection
reset by peer) while reading response header from upstream, client:
xx.xx.xx.xx, server: xx.xx.xx, request: "GET /ben2.php HTTP/1.1", upstream:
"fastcgi://127.0.0.1:9000", host: "xx.xx.xx"
2015/11/28 14:41:08 [error] 12981#0: *798215 connect() failed (110: Connection
timed out) while connecting to upstream, client: xx.xx.xx.xx, server: xx.xx.xx,
request: "GET /ben2.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host:
"xx.xx.xx"
I've tried "request_terminate_timeout, fastcgi_connect_timeout,
fastcgi_read/write_timeout", but no help.
What can I do next step ?
