note 126291 added to install.unix.nginx

To maximize the server performance with highest speed, with fewest resources, i have decided to compile PHP 8 manually from minimal Linux/Unix-based OS (my Linux distro is rpm-based packages) My system has successfully powered up by PHP 8.0.9 - with Opcache/JIT enabled & other several PHP extension module. Here is several experience that may save you several hours of research. 1. Before step (3) - Configure and build PHP - to ensure that no errors occurs, you can refer to my prerequisites library. sudo dnf install \ gcc gcc-c++ make cmake autoconfig \ zlib zlib-devel pcre pcre-devel \ libxml2-devel libxslt-devel \ bzip2-devel curl-devel libzip-devel\ sqlite-devel \ systemd-devel \ openssl-devel \ libffi-devel \ libpng libpng-devel libwebp libwebp-devel libjpeg libjpeg-devel libXpm libXpm-devel \ freetype-devel \ gmp-devel \ libldb-devel \ libc-client libc-client-devel \ openldap openldap-devel \ oniguruma oniguruma-devel \ net-snmp-devel readline-devel unixODBC-devel \ uw-imap uw-imap-devel uw-imap-static uw-imap-utils \ libicu-devel \ enchant2 enchant2-devel \ gd gd-devel \ libsodium libsodium-devel \ libtidy libtidy-devel You may not receive error when issuing ./configure, make && make install. Even when you manually build your PHP extension package later. 2. At step 5 - before modifying php.ini - you may double-check whether the current PHP is reading which php.ini file by this command php -ini | grep php.ini # My result. It is different from tutorial.
