It was pain in the ass to have php-fpm and nginx together to serve php app, especially when you’re running on low-memory server, especially when you’re running cms like wordpress which basically heavy duty. I had a Centos server running with memory only 1024Mb (1Gb).
My web kept crushed every single time. And the problem stil remains, memory leak.
I don’t know what the root cause was. I still don’t know what that is but I think it’s something to do with php-fpm configuration or even nginx.
Just several days ago I had my blog up and running with wordpress in the same type of server, same OS (Centos) with the same memory (1Gb) and since I didn’t want to use apache for some reason, guess I had to get my nginx and php-fpm working together again.
I thought my web would be running very smoothly since the blog was still unlikely to receive much traffic. But I was wrong, somehow the memory was leaked again. My server only running with 1024Mb, but I thought It didn’t matter. The only way to get this problem mitigated is to tune up both the php-fpm and nginx configurations which I never liked this. But I need this, so let’s get this done.
I’m running Centos 6.8 with nginx 1.12.0 & php 5.3.3
After some time, I think I come up with this nicely php-fpm and nginx configured.
nginx configuration :
server {
listen 80;
server_name www.pulpn.com pulpn.com;
charset utf-8;
gzip on;
gzip_vary on;
server_name_in_redirect off;
server_tokens off;
client_header_buffer_size 128;
client_max_body_size 8m;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 32k;
fastcgi_buffers 4 32k;
fastcgi_busy_buffers_size 32k;
fastcgi_temp_file_write_size 32k;
location / {
root /srv/www/myblog;
index index.php;
try_files $uri $uri/ /index.php?q=$uri&$args;
location ~* \.php {
try_files $uri =404;
include fastcgi_params;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass 127.0.0.1:9000;
}
}
}
php-fpm configuration :
[www] ; this config is necessary listen = 127.0.0.1:9000 listen.allowed_clients = 127.0.0.1 listen.owner = nginx listen.group = nginx listen.mode = 0666 user = nginx group = nginx pm = static pm.max_children = 8 pm.start_servers = 10 pm.min_spare_servers = 5 pm.max_spare_servers = 35 pm.max_requests = 1024 request_terminate_timeout = 0 ; this config is just preference, you can change if you want slowlog = /var/log/php-fpm/www-slow.log php_admin_value[error_log] = /var/log/php-fpm/www-error.log php_admin_flag[log_errors] = on php_value[session.save_handler] = files php_value[session.save_path] = /var/lib/php/session
My server after configured, just a quick peek :
