This article introduces the knowledge of "how to upgrade nginx to support HTTP/2 server push". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Upgrade nginx to 1.14.0

1. Configure the official yum source of nginx. Create a configuration file / etc/yum.repos.d/nginx.repo and write the following

[nginx] name=nginx repobaseurl= http://nginx.org/packages/centos/7/$basearch/gpgcheck=0enabled=1

2. Update nginx

Yum update

3. Restart nginx

Systemctl restart nginx

4. Verify the nginx version

$curl-I 127.0.0.1http/1.1 301 moved permanentlyserver: nginx/1.14.0

Modify nginx configuration

Add http2_push_preload on; to the original configuration. When nginx detects the link response header, it actively pushes the resource to the client.

Location. Php$ {#... Omit other configurations http2_push_preload on; # plus this line}

Modify wordpress theme

The http2_push_preload of nginx requires the cooperation of application services. For example, if I want to push the index.js file actively, I need to add the following response header:

Link:; as=script; rel=preload

You can also push multiple files at the same time, such as:

Link:; as=script; rel=preload,; as=style; rel=preload

For wordpress, you can add the following code:

Function add_http2_push_header () {$preload_resource_array = array ('; as=script; rel=preload','; as=style; rel=preload'); $preload_link_value = join (',', $preload_resource_array); header ('link:'. $preload_link_value);} add_action ('send_headers',' add_http2_push_header')

Browser verification

Server push is not supported before upgrading.

After the upgrade, server push is supported.
