Nginx 的502錯誤怎麼解決？
這是php-fpm.log中的日誌記錄：
fpm_got_signal(), line 48: received SIGCHLD
fpm_children_bury(), line 215: child 11877 (pool default) exited on signal 15 SIGTERM after 238.081583 seconds from start
fpm_children_make(), line 352: child 12421 (pool default) started
55 fpm_stdio_prepare_pipes(), line 197: pipe() failed: Too many open files (24)
fpm_request_check_timed_out(), line 158: child 11879, script '/founder/wwwroot/bbs/home.php' (pool default) execution timed

其中nginx的配置文件：
fastcgi_connect_timeout 1000;
fastcgi_send_timeout 1000;
fastcgi_read_timeout 1000;
php-fpm.conf:
<value name="max_children">600</value>
<value name="request_terminate_timeout">5s</value>
《解決方案》
加大 php
