This page covers how to install vichan.

Base Requirements[edit | edit source]

  1. PHP >= 7.4
  2. MySQL/MariaDB server
  3. mbstring
  4. PHP GD
  5. PHP PDO
  6. PHP BCMath
  7. Composer
  8. A Unix-like OS

We try to make sure vichan is compatible with all major web servers. vichan does not include an Apache `.htaccess` file nor does it need one.

Recommended[edit | edit source]

  1. MySQL/MariaDB server >= 5.5.3
  2. ImageMagick (command-line ImageMagick or GraphicsMagick preferred).
  3. APCu (Alternative PHP Cache), Memcached or Redis
  4. Gifsicle

If you have zero experience running a website, has a nice guide on how to set up a web server.

Ubuntu is by far the easiest OS to use to set up any server, providing bleeding edge updates. However, if you seek assurance against 0-day exploits, a stable distro such as Debian or Alpine is preferred. Although they are slower to update their repositories, they are much less likely to be impacted by security vulnerabilities.

Downloading Vichan[edit | edit source]

It is recommended that you utilize git clone to install vichan. This will install the latest version of the software.

Make sure you have navigated in your terminal to whichever directory your webserver is in (commonly /var/www/), or cd /var/www/.

Then clone the repository by entering git clone FolderName (with FolderName being optional). You may need to install git first.

After this finishes, if you did not specify a destination folder you may opt to move the resulting folder (named vichan) to something else (mv vichan NewFolderName).

Next, enter your vichan folder (cd vichan) and run composer (composer install).

If you do not have all needed dependencies installed, composer may fail, in which case it will tell you what is needed.

Configuring the Web server[edit | edit source]

Vichan does not require much of a modified configuration to work.

If you are on the fence on which server to use, Nginx is more commonly used and is notably faster on larger websites. Apache, on the other hand, works more "out of the box" and may be easier to understand if less experienced with running a server. Both servers work well with vichan. If you're using constrained hardware, Lighttpd is a third software that is tailored towards light resource usage.

Apache[edit | edit source]

After installing apache, a simple config like this will work well. This should be located within your /etc/apache2/sites-available directory (this is in /etc/httpd/sites-available for centos or fedora):

<VirtualHost *:80>
	ServerAlias # Optional
	<Directory /var/www/YourVichanFolder>
    		Options -Indexes +FollowSymLinks
    		AllowOverride All
    		Require all granted

	ServerAdmin webmaster@localhost
	DocumentRoot /var/www/YourVichanFolder
	ErrorLog ${APACHE_LOG_DIR}/error.log
	CustomLog ${APACHE_LOG_DIR}/access.log combined

    ErrorDocument 403 /static/403.html
    ErrorDocument 404 /static/404.html

The following site config disables directory listing. Then utilize a2ensite yoursiteconfig and reload apache to start your website.

Nginx[edit | edit source]

A nginx config similar to the following will work for vichan. Make sure that php-fpm is installed (apt-get install php-fpm or dnf install php-fpm).

server {
    root /var/www/YourVichanFolder;

    location / {
        try_files $uri $uri/ =404;
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php8.3-fpm.sock; # Replace with the version of php you are running.
    error_page 403 /static/403.html;
    error_page 404 /static/404.html;

You may also want to edit either the above config or nginx.conf (within the server or http block respectively) to add the following line, which will allow files larger than 1mb.

client_max_body_size 100M; #100 megabytes

Lighttpd[edit | edit source]

server.modules += ("mod_fastcgi")
static-file.exclude-extensions = (".php", ".pl", ".cgi", ".fcgi")
# If using a TCP port:
fastcgi.server = ( ".php" =>
                            ( "localhost" =>
                                            "host" => "",
                                            "port" => "9000"
# If using a Unix socket:
fastcgi.server = ( ".php" =>
                            ( "localhost" =>
                                            "socket"            =>              "/run/lighttpd/lighttpd-fastcgi-php-" + PID + ".socket",
                                            "bin-path"  =>              "/usr/bin/php-cgi"
server.document-root = var.basedir + "/path/to/vichan"
index-file.names = ("index.php", "index.html", "index.htm", "default.htm")

Cloudflare[edit | edit source]

MySQL[edit | edit source]

Vichan will not create a database for you, so you will have to do it yourself. You can use this guide if you do not know how creating users in MySQL/MariaDB works. Or this guide for databases.

All that is needed is to create a user (or use an existing user), create the database, then give that user all permissions for said database.

File Permissions[edit | edit source]

The following files and folders either need to be given to www-data or given 777 permissions:

  • the root vichan directory (non-recursively)
  • inc/secrets.php
  • templates/cache (recursively)
  • tmp/cache (recursively)

Install.php[edit | edit source]

After all above steps are followed, then install.php will begin to function. If it shows a white screen, make sure you ran composer. If you already ran it, check your php-fpm or apache logs to see what is going on.

Install.php will first show the following screen. Make sure to read and accept the agreement.
