ANXS - nginx Build Status

Ansible role which installs and configures Nginx, from a package or from source (including a series of optional modules).

Requirements & Dependencies

Ansible

It has been tested on Ansible 1.5 and above, and depends on the following roles:

  • ANXS.apt
  • ANXS.build-essential
  • ANXS.perl
  • ANXS.monit (if you want monit protection)
Platforms

Currently it's been developed for, and tested on Ubuntu. It is assumed to work on other Debian distributions as well.

Variables

default (nginx.conf)
  • nginx_install_method - "source" or "package"

  • nginx_user - user Nginx will run as

  • nginx_uid - the uid for this user

  • nginx_group - Nginx group

  • nginx_gid - the gid for this group

  • nginx_dir - location of the Nginx configuration (conf, sites-available, sites-enabled, ...)

  • nginx_www_dir - location of the www root for Nginx sites

  • nginx_log_dir - location of the Nginx logs

  • nginx_pid - location of the Nginx PID file

  • nginx_worker_processes - sets the number of worker processes

  • nginx_daemon_disable - whether the daemon should be disabled which can be set to yes or no

  • nginx_worker_rlimit_nofile - used for config value of worker_rlimit_nofile. Can replace any "ulimit -n" command. The value depend on your usage (cache or not) but must always be superior than worker_connections. Set to null to ignore

  • nginx_error_log_options - option flags for the error_log

  • nginx_error_log_filename - filename for the error log

  • nginx_worker_connections - sets the number of worker connections

  • nginx_multi_accept - used for config value of events { multi_accept }. Try to accept() as many connections as possible. Can be set to yes or no

  • nginx_charset - used to specify an explicit default charset (say, 'utf-8', 'off'…)

  • nginx_disable_access_log - whether or not to disable the access log, yes or no

  • nginx_access_log_options - option flags for the access_log

  • nginx_server_tokens - whether to send the Nginx version number in error pages and Server header, on or off

  • nginx_event - used for config value of events { use }. Set the event-model. By default nginx looks for the most suitable method for your OS.

  • nginx_sendfile - directive to activate or deactivate the usage of sendfile(), on or off

  • nginx_keepalive - option whether to use the timeout options (below). Only the value "on" will include them

  • nginx_keepalive_timeout - assigns the timeout for keep-alive connections with the client

  • nginx_client_body_timeout - sets the read timeout for the request body from client

  • nginx_client_header_timeout - specifies how long to wait for the client to send a request header

  • nginx_send_timeout - specifies the response timeout to the client; it does not apply to the entire transfer but, rather, only between two subsequent client-read operations

  • nginx_buffers - option whether to use the buffer options (below). Only the value "on" will include them

  • client_body_buffer_size - specifies the client request body buffer size

  • client_header_buffer_size - sets the headerbuffer size for the request header from client

  • client_max_body_size - specifies the maximum accepted body size of a client request, as indicated by the request header Content-Length. Set to 0 to disable

  • large_client_header_buffers - assigns the maximum number and size of buffers for large headers to read from client request

  • nginx_server_names_hash_bucket_size - assigns the size of basket in the hash-tables of the names of servers. This value by default depends on the size of the line of processor cache

  • nginx_types_hash_max_size -

  • nginx_types_hash_bucket_size -

  • nginx_proxy_read_timeout - defines a timeout (between two successive read operations) for reading a response from the proxied server.

  • nginx_enable_rate_limiting - enable rate limiting, yes or no

  • nginx_rate_limiting_zone_name - sets the shared memory zone

  • nginx_rate_limiting_backoff - sets the maximum burst size of requests

  • nginx_rate_limit - sets the rate (e.g. 1r/s)

  • nginx_access_logs - a list of access log formats, filenames and options

      nginx_access_logs:
        - name: "main"
          format: '$remote_addr - $remote_user [$time_local] "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent"'
          options: null
          filename: "access.log"
    
      #This will generate access_log /var/log/nginx/access.log combined
      nginx_access_logs:
        - name: "combined"
          filename: "access.log"
    
  • nginx_default_root - the directory to place the default site

  • nginx_default_enable - whether or not to actually enable the defaul site

source
  • nginx_source_version - the version of Nginx to install
  • nginx_source_url - URL for the Nginx source (versioned). By default it will get it from nginx_source_version
  • nginx_source_prefix - prefix for installing nginx from source (versioned)
  • nginx_source_conf_path - location of the main config file (in nginx_dir by default)
  • nginx_source_default_configure_flags - the default configure flags (before adding the modules). By default, this sets --prefix, --conf-path and --sbin-path
  • nginx_source_modules_included - see below
  • nginx_source_modules_excluded - a list of configure flags to exclude modules. Example: ["mail_pop3_module", "mail_imap_module", "mail_smtp_module"]

nginx_source_modules_included is a dictionary (k,v) where k is the module name, and v its accompanying configure flag. All the possible options are given below:

nginx_source_modules_included:
  http_stub_status_module: "--with-http_stub_status_module"
  http_ssl_module: "--with-http_ssl_module"
  http_gzip_static_module: "--with-http_gzip_static_module"
  upload_progress_module: "--add-module=/tmp/nginx-upload-progress-module-{{nginx_upload_progress_version}}"
  headers_more_module: "--add-module=/tmp/headers-more-nginx-module-{{nginx_headers_more_version}}"
  http_auth_request_module: "--add-module=/tmp/ngx_http_auth_request_module-{{nginx_auth_request_release}}"
  http_echo_module: "--add-module=/tmp/echo-nginx-module-{{nginx_echo_version}}"
  google_perftools_module: "--with-google_perftools_module"
  ipv6_module: "--with-ipv6"
  http_real_ip_module: "--with-http_realip_module"
  http_spdy_module: "--with-http_spdy_module"
  http_perl_module: "--with-http_perl_module"
  naxsi_module: "--add-module=/tmp/naxsi-{{nginx_naxsi_version}}/naxsi_src"
  ngx_pagespeed: "--add-module=/tmp/ngx_pagespeed-release-{{nginx_ngx_pagespeed_version}}-beta"
  http_geoip_module: "--with-http_geoip_module"
Sites

There is a possibility to configure a list of servers to be available (not yet enabled) as well. Just provide a list of dictionaries according to the following format:

nginx_sites:
  - server:
      name: foo
      listen: 8080
      server_name: localhost
      location1:
        name: "/"
        try_files: "$uri $uri/ /index.html"
        sendfile: "on"
  - server:
      name: bar
      listen: 8888
      server_name: webmail.localhost
      location1:
        name: /
        try_files: "$uri $uri/ /index.html"
      location2:
        name: /images/
        try_files: "$uri $uri/ /index.html"

To enable or disable specific sites you can add prior used server_name attribute to the variables nginx_enabled_sites and nginx_disabled_sites.

nginx_enabled_sites:
  - localhost
nginx_disabled_sites:
  - webmail.localhost
Monit ?

You can put Nginx under monit monitoring protection, by setting monit_protection: yes

Testing

This project comes with a VagrantFile, this is a fast and easy way to test changes to the role, fire it up with vagrant up.

See vagrant docs for getting setup with vagrant

There are two ways to test the install: compiling nginx from source or installing from a package manager. By default nginx compiles from source, however if desired, we can set a command line variable to install from the package manager

export NGINX_INSTALL_METHOD=package
