Dokážeš vytáhnout nějaké podezřelé logy z toho PHP-FPM a zkusit uhodnout, proč to dělá ? --Věroš Kaplan http://veroskaplan.cz/ <http://veroskaplan.cz/> Školíme Ansible: http://ansible.cz/ <http://ansible.cz/> 2015-12-02 8:25 GMT+01:00 Branislav Viest &lt;info(a)branoviest.com <mailto:info@branoviest.com>>: Ahoj, mám tady jeden server kde je cca 35k lidí za vteřinu. Běží tu nginx + php fpm a mysql db. V nginxu jsem rozjel microcache, což hodně ulevilo zátěži serveru. Nicméně, mám problém s PHPkem. FPM běží přes TCP (zkoušel jsem i unix socket nicméně bylo to pomalější a docházelo ke stejnému problému). Dle error logu dochází k těmto chybám: 2015/12/01 23:26:56 [error] 27043#0: *122476 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 188.114.98.51, server: xxx request: "GET /xxx/xxxx/xxx HTTP/1.1", upstream: "fastcgi://MailScanner has detected a possible fraud attempt from "127.0.0.1:9000" claiming to be MailScanner warning: numerical links are often malicious: 127.0.0.1:9000 <http://127.0.0.1:9000/>", host: "xxxx", referrer: "MailScanner has detected a possible fraud attempt from "xxxxx" claiming to be http://xxxxx <http://xxxxx/>" 2015/12/01 23:26:56 [error] 27032#0: *124368 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 188.114.99.50, server: xxxxxx, request: "GET /xxxxx/xxxxx HTTP/1.1", upstream: "fastcgi://MailScanner has detected a possible fraud attempt from "127.0.0.1:9000" claiming to be MailScanner warning: numerical links are often malicious: 127.0.0.1:9000 <http://127.0.0.1:9000/>", host: "xxxxx", referrer: "xxxxx" a sype to tam docela drsně. Jak vypnu kešování v nginxu load vyskočí, třeba i na 500, těch chyb PHPka je méně ale jsou tam pořád. Konfigurace FPM pro pool toho webu je: [web1] listen = MailScanner has detected a possible fraud attempt from "127.0.0.1:9000" claiming to be MailScanner warning: numerical links are often malicious: 127.0.0.1:9000 <http://127.0.0.1:9000/> listen.allowed_clients = 127.0.0.1 listen.owner = web1 listen.group = client0 listen.mode = 0660 listen.backlog = 65536 user = web1 group = client0 request_slowlog_timeout = 5s slowlog = /var/log/php-fpm/slowlog-web1.log pm = dynamic pm.max_children = 7000 pm.start_servers = 4000 pm.min_spare_servers = 2000 pm.max_spare_servers = 4000 pm.max_requests = 100 request_terminate_timeout = 60s rlimit_files = 500000 rlimit_core = unlimited catch_workers_output = yes pm.status_path = /php-status chdir = / + openbasedir, sessions save path. atp. S těma hodnotama jsem se zkoušel různě hrát, nicméně to k vyřešení tohoto problému nepomohlo. Zkoušel jsem upravit i nějaké parametry jádra (local port range, tcp ack timeouty atp.) ale výsledek stejný. Dělá to i u unix socketu, což je mi právě zvláštní. Nginx konfigurace je: user www-data; worker_processes 80; pid /run/nginx.pid; # set open fd limit to 50000 worker_rlimit_nofile 100000; events { worker_connections 1024; multi_accept on; use epoll; } ve vhostu nic zvlastniho, jenom pro php: fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name; include /etc/nginx/fastcgi_params; fastcgi_pass MailScanner has detected a possible fraud attempt from "127.0.0.1:9000" claiming to be MailScanner warning: numerical links are often malicious: 127.0.0.1:9000 <http://127.0.0.1:9000/>; fastcgi_index index.php; fastcgi_intercept_errors on; fastcgi_read_timeout 4m; Dnes bude k tomuto server nový, pro rozdělení zátěže, ale jako fakt nevím jestli to má smysl ve stejné konfiguraci, kvůli těm php chybám. Nenapadá Vás kluci, co s tím? Nebo případně návrh řešení, kterým bych nahradil tohle, při dvou serverech ? Přemýšlím nad MySQL M - M replikací, v DNS round robin a GlusterFS pro data. Ale to phpko mi nedá spát. A dnes večer to už další nápor asi nedá. Díky za rady a konzultace.
