In the config' /etc/nginx/sites-enabled/default, the directives listen are like
this:
listen 80;
listen [::]:80 default_server;But I found this in the nginx doc' (http://wiki.nginx.org/HttpCoreModule#listen), " When you enable the address [::]:80, binding port 80 using IPv6, in the listen directive, in Linux, by default, the IPv4 port 80 is also enabled. Meaning that nginx listens for both IPv4 and IPv6 incoming traffic. Therefore if you erroneously specify also a IPv4 address you'll get an already bind address error when reloading nginx configuration. " SOLUTION 1 - remove directive "liste 80;", (pay attentioon if you need to set up a second virtual host, you will have to separate IPv4 and IPv6 stacks; see solutions 2 and 3) SOLUTION 2: - separate IPv4 and v6 stacks using net.ipv6.bindv6only and set its value to 1. SOLUTION 3: - separate IPv4 and v6 stacks using the ipv6only option and replace this line: - listen [::]:80 default_server; + listen [::]:80 default_server ipv6only=on; I personnaly use the third solution. -- Jean-Marc <jean-m...@6jf.be>
