linux centos6.8下 php连接redis读取数据间歇性502解决

Posted 2021-02-04 victorcode

nginx报错提示：

*963623 recv() failed (104: Connection reset by peer) while reading response header from upstream ..

php-fpm.log报错提示：

WARNING: [pool www] child 10559 exited on signal 11 (SIGSEGV) after 0.504455 seconds from start ..

解决：(服务器出现502错误 可能进程过多导致)

修改 php-fpm.conf    pm.max_children  设置的尽可能高一些

pm = dynamic
pm.max_children = 60  
pm.start_servers = 30
pm.min_spare_servers = 30
pm.max_spare_servers = 60

重启php-fpm即可 。
