How to reboot CentOS 7 with Ansible?

Apache 2.4 and php-fpm does not trigger apache http basic auth for php pages
apache,proxy,php-fpm,fcgi,centos7
After hours of research I understood that the reason that this occurs is because the ProxyPassMatch directive is the first directive to be processed, and this causes apache to ignore the other directives for the .php extensions. To be able to use other apache directives with php-fpm via the proxy_fcgi_module...

SMTP (port 25) Plesk 12 on CentOS 7 “None of the authentication methods supported by your server”

Server doesn't provide auth, it may be because of "smtpd_tls_auth_only = yes" in /etc/postfix/main.cf. "smtpd_tls_auth_only = yes" forbid authentication on non-secure connection like port 25. You can just change it to "no", or try using secure port 465 in Android Mail Client. It's quite easy to check your SMTP server...

Cloud Init Fails to Install Packages on CentOS 7 in EC2
Evidently there was a bug fixed with later versions of the image. If this is happening to you, it may be a legitimate bug in Cloud-Init or your servers implementation of it. A package upgrade may fix the problem, also an update to the image will fix it globally.
Php has its own /tmp in /tmp/systemd-private-nABCDE/tmp when accessed through nginx
