I have debian machine and currently apache prefork. I would like to switch to worker mode. I found in phpinfo that these modules are installed: 

core 
mod_so 
mod_watchdog 
http_core 
mod_log_config 
mod_logio 
mod_version 
mod_unixd 
mod_access_compat 
mod_alias 
mod_auth_basic 
mod_authn_core 
mod_authn_file 
mod_authz_core 
mod_authz_host 
mod_authz_user 
mod_autoindex 
mod_deflate 
mod_dir 
mod_env 
mod_filter 
mod_mime 
prefork 
mod_negotiation 
mod_php7 
mod_reqtimeout 
mod_rewrite 
mod_setenvif 
mod_socache_shmcb 
mod_ssl 
mod_status

How can I find out, if all modules will work correctly with worker mode please?

Don't use mod_php with MPM worker or event, it's not thread-safe. Switch to mod_proxy_fcgi and php-fpm, read Running PHP on Apache httpd. - Freddy
hi, am I able to find out, which modules are thread-safe? - peter
I believe the modules that come with Apache are considered all safe, go throught the list and check the Module Index. yourself. Read Apache HTTP Server 2.x Thread Safety Issues and disable all modules you don't actually use. - Freddy
