This instance of DokuWiki is installed along with NGINX on Fedora Server 29. This page describes the installation process for future references.

dnf install nginx php-fpm php-json
systemctl start nginx
systemctl enable php-fpm
systemctl enable nginx

firewall-cmd --list-all
firewall-cmd --permanent --remove-service=cockpit
firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --add-service=https
firewall-cmd --reload

vim /etc/nginx/nginx.conf

    root /var/www/html;

systemctl reload nginx

The RPM package sets the user and group to apache. I want it to run under nginx instead.

vim /etc/php-fpm.d/www.conf 

    user nginx
    group nginx

systemctl reload php-fpm

wget https://download.dokuwiki.org/src/dokuwiki/dokuwiki-stable.tgz
tar xf dokuwiki-stable.tgz 
cd /var/www/html
cp -r ~/dokuwiki-2018-04-22b/ wiki
chown nginx:nginx -R wiki

Fedora has SELinux enabled by default, which prevents DokuWiki from modifying files under /var/www.

I didn't go this route because it looks dangerous.

sestatus 
getenforce 
setenforce 0

dnf install policycoreutils-python-utils
semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/wiki/.*'
cd wiki
ls -Z
restorecon -v -R .

I didn't test this but it should work.

semanage permissive -a httpd_t

DokuWiki installation process needs password inputs, so installing HTTPS certificates MUST come before that.

dnf install certbot-nginx
certbot --nginx

crontab -e

    0 0,12 * * * python -c 'import random; import time; time.sleep(random.random() * 3600)' && certbot renew

crontab -l

Before going through install.php, I configured NGINX as follows.

vim /etc/nginx/nginx.conf

    http {
        types_hash_max_size 4096;
        server {
            location = / {
                return 302 https://$host/wiki/;
            }
            location ~ /(conf|bin|inc)/ {
                deny all;
            }
            location ~ /data/ {
                internal;
            }
        }
    }

systemctl reload nginx

After going through install.php, remove it.

I followed https://www.dokuwiki.org/rewrite#nginx and the following options were needed.

vim conf/local.php

    $conf['basedir'] = '/wiki/';
    $conf['userewrite'] = '1';
    $conf['useslash'] = 1;

vim /etc/nginx/nginx.conf

    http {
        server {
            location /wiki/ {
                index doku.php;
                try_files $uri $uri/ @dokuwiki;
            }
            location @dokuwiki {
                rewrite	^/wiki/_media/(.*)		/wiki/lib/exe/fetch.php?media=$1 last;
                rewrite	^/wiki/_detail/(.*)		/wiki/lib/exe/detail.php?media=$1 last;
                rewrite	^/wiki/_export/([^/]+)/(.*)	/wiki/doku.php?do=export_$1&id=$2 last;
                rewrite	^/wiki/(?!lib/)(.*)		/wiki/doku.php?id=$1&$args last;
            }
        }
    }
