In Linux, how does one set up a Web environment to disable iptables and selinux?

Disable iptables and selinux when you configure LNMP and samba. it was previously used to solve the problem, and it was disabled for whatever reason, so as to avoid trouble. If this problem occurs in the past few days, I would like to return and ask: 1. if a simple lnmp production server is set up, shut them down... disable iptables and selinux when you configure LNMP and samba. it was previously used to solve the problem, and it was disabled for whatever reason, so as to avoid trouble.
If this problem occurs in the past few days, I would like to return and ask:

1. if a simple lnmp production server is set up, does it reduce the security of the server? Are you sure you want to disable it? How should we set them?

By the way, I have another question. Why can't I use eaccelerator for php5.6?

It is convenient to turn it off, but you need to pay attention to whether all software has vulnerabilities that can be exploited. To put it simply, if there is no sensitive information on the server, it is better to turn it off during development and enable and configure it after going online.

PHP now has the official opcache code cache extension, and other similar extensions are basically dying.
