nginx config help (getting started)

[LuisManson]

Hi, im just migrating my server to a P3, 2Gb RAM, 500Gb HD. I just became interested on the benefits of nginx/php-fpm over apache and im trying to move to this environment from a FreeBSD/Apache setup

my site has almost 300 users online on top hour...
4K visits/day
400K page views/day
1M hits/day
4Gb transfered/day

i need some exmaple config files of a working site or an optimized config, since im an apache/mod_php guy im reaaaaly lost here...

thanks!

you can try this

nginx.conf
events {
worker_connections 6000;
}
worker_processes 12;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 10;
gzip on;
gzip_comp_level 2;
gzip_proxied any;
gzip_types text/plain text/html text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;

php-fpm.conf
<value name="max_children">3000</value>
<value name="StartServers">200</value>
<value name="MinSpareServers">600</value>
<value name="MaxSpareServers">2000</value>
<value name="request_terminate_timeout">10s</value>

With 300 people online at your peak time, there is no reason to start nginx or php-fpm with that many connections, there is no way you will use them, they are also going to use resources better spent in other places.

Start them off with their default connection limits in place, consider raising them if your traffic increases.

You should adjust these values based on your sites traffic & content, NOT by what others are using, these values should reflect your needs.

Basic optimized configuration:

client_header_timeout           10m;
        client_body_timeout             10m;
        send_timeout                    10m;
        client_max_body_size            10m;
        client_body_buffer_size         10m;
        connection_pool_size            256;
        client_header_buffer_size       8k;
        large_client_header_buffers     4 32k;
        request_pool_size               8k;

        gzip                            on;
        gzip_min_length                 1100;
        gzip_buffers                    8 16k;
        gzip_comp_level                 1;
        gzip_types                      text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;
        gzip_disable                    "MSIE [1-6]\.";

        output_buffers                  1 32k;
        postpone_output                 1460;

        sendfile                        on;
        tcp_nopush                      on;
        tcp_nodelay                     on;

        server_names_hash_max_size      4096;
        server_names_hash_bucket_size   128;

        keepalive_timeout               75 20;

        ignore_invalid_headers          on;

        fastcgi_connect_timeout         60;
        fastcgi_send_timeout            180;
        fastcgi_read_timeout            180;
        fastcgi_buffer_size             8k;
        fastcgi_buffers                 4 128k;
        fastcgi_busy_buffers_size       256k;
        fastcgi_temp_file_write_size    256k;
        fastcgi_intercept_errors        on;
        index                           index.php;

        proxy_buffering                 on;
        proxy_buffer_size               4k;
        proxy_buffers                   8 32k;

The above is for a site pumping a lot of content, with a lot of ads, with multiple sites hosted, in the header etc, again base these settings off your site.

With 2500 online:

nginx.conf
worker_processes                        8; <-- 1 per core
worker_rlimit_nofile                    4096;

events {
                                        worker_connections 1024;
                                        use epoll;
}


php-fpm.conf
listen.backlog = -1
pm = dynamic
pm.max_children = 50
pm.start_servers = 15
pm.min_spare_servers = 10
pm.max_spare_servers = 25
pm.max_requests = 500

With 4000 online, different server/forum

nginx.conf
worker_processes                        16; <-- 1 per core
worker_rlimit_nofile                    4096;

events {
                                        worker_connections 2048;
                                        use epoll;
}


php-fpm.conf
listen.backlog = -1
pm = dynamic
pm.max_children = 10
pm.start_servers = 35
pm.min_spare_servers = 15
pm.max_spare_servers = 50
pm.max_requests = 1024

And do these benefits exactly match your existing setup and configuration and usage data that there's a real benefit ?

Without any usage datas and building a configuration upon these matching exactly the needs there won't be much speedup by changing some software.

[LuisManson]

thank you very much snakes1100 , i will definitely go to try to use something from that info!!!


Angel-Wings: im not sure, but if i dont try how do i know if its better?
Yet, my new hardware is a bit smaller, so i think this will be an improvement some how, i lost a bit on hardware now, but i also migrate to a lighter software

about my usage data, what do you ask specifically?
i obviously wont just copy/paste the examples posted here, since everyone has different needs, but i needed a starting base

thanks Marco, im actually interested on real work config examples, not sure if support also has own boards with vb and different environments

[Marco van Herwaarden]

Both Eva2000 (official support) and other users may respond in that forum. Eva2000 (George) is very experienced in running many different environments.

Bottom line is that it is better to have such specialized information in a single place.
