How to enable compression on the server?

Question

htaccess

Hello.
PageSpeed ​​says enable compression, how to implement it correctly?
In server settings enabled mod_deflate
in htaccess added:

<ifModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/plain text/xml application/xml application/xhtml+xml text/css text/javascript application/javascript application/x-javascript
</ifModule>

now htaccess looks like this:

<ifModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/plain text/xml application/xml application/xhtml+xml text/css text/javascript application/javascript application/x-javascript
</ifModule>

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule .* index.php [L]

But PageSpeed ​​still swears and says enable compression

1. is there mod_deflate?
2. Are these settings ignored in .htaccess files by Apache?
