Nginx

Modified: 28 Apr 2022 01:26 UTC

The Joyent Nginx images is a SmartOS base64 image pre-configured with Nginx, a high performance web and proxy server.

You can find more information about Nginx at their website.

Overview

Nginx comes pre-installed and tuned according to your VM size under the www user as the SMF service svc:/pkgsrc/nginx:default. The instance also comes pre-configured with a virtual host listening on all interfaces with PHP support.

Directory layout

The directory and file layout is as follows:

Directory/File Description
/opt/local/sbin Holds Nginx server binaries
/opt/local/etc/nginx The configuration directory for Nginx
/opt/local/etc/nginx/virtualhosts The virtual hosts configuration directory for Nginx
/var/log/nginx Where Nginx access and error logs are kept
/var/log/php-fpm.log Log file for php-fpm
/home/admin/web/public Docroot for the default virtual host

Starting Nginx

By default nginx comes enabled. You can disable, restart the service with:

    # svcadm disable pkgsrc/nginx

or restart:

    # svcadm restart pkgsrc/nginx

To check the status of the service:

    # svcs pkgsrc/nginx
    online         May_12   svc:/pkgsrc/nginx:default

Configuration

The Nginx configuration files are stored at /opt/local/etc/nginx and virtual host files at /opt/local/etc/nginx/virtualhosts.

Virtual hosts

Default virtual host

By default the instance comes pre-configured with a virtual host listening on all interfaces. The configurations for these are at /opt/local/etc/nginx/virtualhosts/<x.x.x.x>.conf with docroot directory /home/admin/web/public. If this configuration works for you (behind a load balancer) then you can just drop in your static files there.

Create a virtual host with sm-create-vhost

To add a new virtual host you can enter one in manually in the configuration directory (/opt/local/etc/nginx/virtualhosts) or use the sm-create-vhost helper script which comes in the smtools package.

Creating a new virtual host with sm-create-vhost:

    # sm-create-vhost nginx example.com /home/admin/web/example.com
    * Created /opt/local/etc/nginx/virtualhosts directory.
    * Created Nginx configuration /opt/local/etc/nginx/virtualhosts/example.com.conf.
      Settings:
        Hosts:   example.com *.example.com www.example.com
        Port:    80
        Docroot: /home/admin/web/example.com

      For changes to take you will need:

      include /opt/local/etc/nginx/virtualhosts/*;

      in your /opt/local/etc/nginx/nginx.conf http{} block and restart nginx with
      svcadm restart pkgsrc/nginx.

      If you want PHP support with nginx you will need to
      svcadm enable svc:/pkgsrc/php-fpm.

All virtual hosts come with PHP support as long as php-fpm is enabled.

Memory usage

Monitoring the processes memory usages is easy with project support.

Nginx memory usage can be monitored under the nginx project using prstat -J. PHP memory usage can also be monitored this way under the php project.

    # prstat -J
    PROJID    NPROC  SWAP   RSS MEMORY      TIME  CPU PROJECT
         0       16   72M   44M   0.0%   0:00:58 0.0% system
       925        2   18M 5548K   0.0%   0:00:00 0.0% nginx
       926        3   68M 9876K   0.0%   0:00:00 0.0% php

DTracing Nginx

The dtracetools package comes with a Nginx sample script dtrace-nginx_reqsec.d to show req/sec. Run it with -p specifying the pid of the nginx process.

    # dtrace-nginx_reqsec.d -p <pid of nginx>

You can view Nginx function entry and return points with the one-liner:

    # dtrace -Fn 'pid$target:nginx::entry { } pid$target:nginx::return {}' -p <pid of nginx>
    dtrace: description 'pid$target:nginx::entry ' matched 2460 probes
    CPU FUNCTION
     21  -> ngx_time_update
     21    -> ngx_gmtime
     21    <- ngx_gmtime
     21    -> ngx_sprintf
     21      -> ngx_vslprintf
     21        -> ngx_sprintf_num
     21        <- ngx_sprintf_num
     21        -> ngx_sprintf_num
    ...

You can view Nginx file opens with this one-liner:

    # dtrace -n 'pid$target::open*:entry { trace(copyinstr(arg0)) }' -p <pid of nginx>
    dtrace: description 'pid$target::open*:entry ' matched 14 probes
    CPU     ID                    FUNCTION:NAME
      9  69701                       open:entry   /opt/local/share/examples/nginx/html/test.html
