Nginx
We're planning to move to Nginx with PHP-FPM for faster execution and throughput for QualityBox.
The Nginx webiste has both examples for PHP-FPM and a Nginx recipe to serve MediaWiki

Always test your configuration file for syntax errors with nginx -t before restarting nginx.
Debugging[edit | edit source]
While working with nginx, if you use option -V then you get the full configuration of the current install (this from a local virtual machine):
nginx version: nginx/1.14.0 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) built with OpenSSL 1.0.2k-fips 26 Jan 2017 TLS SNI support enabled configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --htt p-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache /nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --gr oup=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --w ith-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module -- with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie'
Check whether debugging was enabled at compile time: nginx -V 2>&1 | grep -- '--with-debug' If the binary is not built for debugging, then you will not be able to see any debug log messages in the log file, and you won't be able to generate a core-dump or config dump as described at Debugging.
File Not Found[edit | edit source]
I kept getting 404's and one possibility to eliminate is whether or not your server has read access to the filesystem. You can check with:
# -H for set 'home' from /etc/password
# -lmo for long, mode, owners
sudo -H -u nginx namei -lmo /var/www/mediawiki
