NGINX_HTTP_Push_Module是一个Nginx服务器模块，可以实现服务器端的长连接和推送（但是推送一次后会结束进程，尚未实现持续的推送）。
NGINX_HTTP_Push_Module是一个Nginx服务器模块，可以实现服务器端的长连接和推送（但是推送一次后会结束进程，尚未实现持续的推送）。



http://pushmodule.slact.net可以下载该模块。

如果已安装Nginx，需要重新编译安装Nginx，要用命令"./configure --add-module=/home/hfahe/ngnix_http_push_module"来配置，然后执行make和make install来安装Nginx。

安装完成后，在Nginx配置文件的Server段里添加两个路径配置：

location /publish {
    set $push_channel_id $arg_id;
    push_publisher;
    push_store_messages on;
    push_message_timeout 2h;
    push_max_message_buffer_length 10;
}
location /activity {
    push_subscriber;
    set $push_channel_id $arg_id;
    push_subscriber_concurrency broadcast;
    default_type text/plain;
}

重启Nginx后，请求http://localhost/activity?id=10000的地址，可以看到浏览器处于请求堵塞阶段。



use LWP::UserAgent; use HTTP::Request::Common; my $ua = new LWP::UserAgent; my $response = $ua->request(   POST 'http://localhost//publish?id=10000',   Content_Type => 'text/html',   Content => 'Server Push' ); my $content = $response->content; print $content;

Can't locate LWP/UserAgent.pm in @INC (@INC contains: /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.8/i386-linux-thread-multi /usr/lib/perl5/5.8.8 .) at post.per line 1.

Can't locate LWP/UserAgent.pm in @INC
It looks as though @INC for you doesn't include a version of perl with LWP::UserAgent.pm installed, whereas @INC for the webserver (usually 'nobody') does use a version of perl with the module.

for this install libwww-perl this will fix it ask Admin to do it


所以:

apt-get install libwww-perl
Centos:
yum install perl-libwww-perl
etting up Install Process
