Sådan installeres DokuWiki på CentOS 7

DokuWiki is an open source wiki software written in PHP that doesn't require a database. It stores data in text files. DokuWiki source code is publicly hosted on GitHub. This guide will show you how to install DokuWiki on a fresh CentOS 7 Vultr instance.

Requirements

Make sure your server meets the following requirements.

• Web server software that supports PHP (Apache, Nginx, IIS, Lighttpd, LiteSpeed)
• PHP version 5.6 or later

Before you Begin

Check the CentOS version.

cat /etc/centos-release
# CentOS Linux release 7.4.1708 (Core)

Create a new non-root user account with sudo access and switch to it.

useradd -c "John Doe" johndoe && passwd johndoe
usermod -aG wheel johndoe
su - johndoe

NOTE: Replace johndoe with your username.

Set up the timezone.

timedatectl list-timezones
sudo timedatectl set-timezone 'Region/City'

Ensure that your system is up to date.

sudo yum update -y

Install required and useful packages.

sudo yum install -y wget vim bash-completion

Disable SELinux.

sudo setenforce 0

Step 1 - Install PHP and PHP extensions

I denne vejledning vil vi bruge PHP 7.1, som ikke er tilgængelig i standard CentOS-depoterne, så du bliver nødt til at bruge et tredjeparts-depot, såsom Webtatic. Følg denne Vultr-artikel for at installere PHP 7, før du fortsætter med denne artikel.

Installer PHP 7.1 og nødvendige PHP-udvidelser.

sudo yum install -y php71w php71w-cli php71w-fpm php71w-gd php71w-xml php71w-zip

Tjek versionen.

php --version

# PHP 7.1.14 (cli) (built: Feb  4 2018 09:05:29) ( NTS )
# Copyright (c) 1997-2018 The PHP Group
# Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies

Start og aktiver PHP-FPM.

sudo systemctl start php-fpm.service
sudo systemctl enable php-fpm.service

Trin 2 - Installer og konfigurer Nginx

Hvis du foretrækker Apache eller en anden populær webserver, kan du bruge en af ​​dem i stedet for Nginx.

Installer Nginx.

sudo yum install -y nginx

Tjek versionen.

nginx -v
# nginx version: nginx/1.12.2

Start og aktiver Nginx.

sudo systemctl start nginx.service
sudo systemctl enable nginx.service

Konfigurer Nginx.

sudo vim /etc/nginx/conf.d/dokuwiki.conf

Kopier/indsæt følgende Nginx-konfiguration og gem den.

server {
    listen [::]:80;
    listen 80;

    server_name wiki.example.com; # Replace with your hostname
    root /var/www/dokuwiki;
    index index.html index.htm index.php doku.php;

    client_max_body_size 15M;
    client_body_buffer_size 128K;

    location / {
        try_files $uri $uri/ @dokuwiki;
    }

    location ^~ /conf/ { return 403; }
    location ^~ /data/ { return 403; }
    location ~ /\.ht { deny all; }

    location @dokuwiki {
        rewrite ^/_media/(.*) /lib/exe/fetch.php?media=$1 last;
        rewrite ^/_detail/(.*) /lib/exe/detail.php?media=$1 last;
        rewrite ^/_export/([^/]+)/(.*) /doku.php?do=export_$1&id=$2 last;
        rewrite ^/(.*) /doku.php?id=$1 last;
    }
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index  index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

Tjek konfigurationen.

sudo nginx -t

Genindlæs Nginx.

sudo systemctl reload nginx.service

Trin 3 - Installer DokuWiki

Opret en dokumentrodmappe.

sudo mkdir -p /var/www/dokuwiki

Skift ejerskab af /var/www/dokuwikibiblioteket til johndoe.

sudo chown -R johndoe:johndoe /var/www/dokuwiki

Naviger til dokumentroden.

cd /var/www/dokuwiki

Download the newest stable release of DokuWiki from the DokuWiki download page.

wget https://download.dokuwiki.org/src/dokuwiki/dokuwiki-stable.tgz

Unpack the DokuWiki tarball.

tar xvf dokuwiki-stable.tgz
rm dokuwiki-stable.tgz
mv dokuwiki-2017-02-19e/* . && mv dokuwiki-2017-02-19e/.* .
rmdir dokuwiki-2017-02-19e/

Change ownership of the /var/www/dokuwiki directory to nginx.

sudo chown -R nginx:nginx /var/www/dokuwiki

Run sudo vim /etc/php-fpm.d/www.conf and set the user and group to nginx.

sudo vim /etc/php-fpm.d/www.conf
# user = nginx
# group = nginx

Restart php-fpm.service.

sudo systemctl restart php-fpm.service

As the last step, run the DokuWiki setup script install.php in your browser and setup DokuWiki. The script checks for the availability of required PHP functions and checks for needed file permissions. It also creates an initial administrator account and an initial ACL policy. To run the installer, open http://wiki.example.com/install.php in the browser and follow the instructions.

Upon successful configuration, delete the install.php file from the DokuWiki root directory.

sudo rm /var/www/dokuwiki/install.php

Congratulations, DokuWiki is installed and you will be able to access and edit a functional wiki at http://wiki.example.com/. Enjoy your new DokuWiki installation.
