1. 下载
http://pushmodule.slact.net/downloads/nginx_http_push_module-0.69.tar.gz
2. 编译nginx
1).解压nginx_http_push_module
tar -zxvf nginx_http_push_module-0.69.tar.gz
2).编译安装nginx_http_push_module
# ./configure --prefix=/usr/local/$NAME --sbin-path=/usr/local/sbin/$NAME.$VERSION --conf-path=/etc/nginx/nginx.conf --pid-path=/var/run/nginx.8.x.pid --http-log-path=/var/log/nginx/8.x.access.log --error-log-path=/var/log/nginx/8.x.error.log --user=nginx --group=nginx --with-openssl=/usr/lib/ssl/ --with-http_stub_status_module --with-http_flv_module --with-http_sub_module --add-module=/to/path/nginx_http_push_module
# sudo make
# sudo make install
3. 添加 nginx conf
location /pub {
set $push_channel_id $arg_id; #/?channel=239aff3 or some-such
push_publisher;
push_message_timeout 2h; # expire buffered messages after 2 hours
push_max_message_buffer_length 10; # store absolutely at most 10 messages
push_min_message_recipients 0; # minimum recipients before purge
}
location /sub {
set $push_channel_id $arg_id;
push_subscriber;
# how multiple subscriber requests to the same channel id are handled
# - last: only the most recent subscriber request is kept, 409 for others.
# - first: only the oldest subscriber request is kept, 409 for others.
# - broadcast: any number of subscriber requests may be long-polling.
push_subscriber_concurrency broadcast;
#/?channel=239aff3 or some-such
default_type text/plain;
}
4. http 客户端 例子

});
var dummy = new Dumbchat(chatEl.getElement("form"), chatEl.getElement("ul"), "http://www.domain.com/sub?id=1", Cookie.read('chatname')).connect();
//user renaming stuff

});
}
});
</script>
