# A list of hashs that define the servers for nginx,
# as with http parameters. Any valid server parameters
# can be defined here.
nginx_sites:                                         
 - server:                                           
    file_name: foo
    listen: 8080
    server_name: localhost
    root: "/tmp/site1"
    location1: {name: /, try_files: "$uri $uri/ /index.html"}
    location2: {name: /images/, try_files: "$uri $uri/ /index.html"}
 - server:
    file_name: bar
    listen: 9090
    server_name: ansible
    root: "/tmp/site2"
    location1: {name: /, try_files: "$uri $uri/ /index.html"}
    location2: {name: /images/, try_files: "$uri $uri/ /index.html"}

Examples

1. Install nginx with HTTP directives of choices, but with no sites configured:

   • hosts: all roles:
     • {role: nginx, nginx_http_params: { sendfile: "on", access_log: "/var/log/nginx/access.log"}, nginx_sites: none }

2. Install nginx with different HTTP directives than previous example, but no sites configured.

   • hosts: all roles:
     • {role: nginx, nginx_http_params: { tcp_nodelay: "on", error_log: "/var/log/nginx/error.log"}, nginx_sites: none }

Note: Please make sure the HTTP directives passed are valid, as this role won't check for the validity of the directives. See the nginx documentation for details.

3. Install nginx and add a site to the configuration.

   • hosts: all

     roles:

     • role: nginx, nginx_http_params: sendfile: "on" access_log: "/var/log/nginx/access.log" nginx_sites:
       • server: file_name: bar listen: 8080 location1: {name: "/", try_files: "$uri $uri/ /index.html"} location2: {name: /images/, try_files: "$uri $uri/ /index.html"}

Note: Each site added is represented by list of hashes, and the configurations generated are populated in /etc/nginx/conf.d/

The file name for the specific site configurtaion is specified in the hash with the key "file_name", any valid server directives can be added to hash. For location directive add the key "location" suffixed by a unique number, the value for the location is hash, please make sure they are valid location directives.

4. Install Nginx and add 2 sites (different method)
