In this Howto I will show you to install Nextcloud 15 on a Plesk VPS with nginx only

If we have root access to the server, we can also use redis-server as memcache.

The following command installs the appropriate package:

sudo apt-get install redis-server

Prepare vHost:

In Plesk we create the subdomain under domains:

 

 

and secure it with LetsEncrypt:

 

 

Within the subdomain we use the file manager:

 

 

and remove all files and directories:

 

 

Now we have to download the Nextcloud-Webinstaller from the following URL to our workstation:

Nextcloud Webinstaller

Afterwards we upload it to our Webspace in Plesk:

 

In Apache/NGINX settings of the subdomain, we set the following values for Additional nginx directives (Customize Domain / Subdomain):

rewrite ^/.well-known/host-meta /public.php?service=host-meta last;
rewrite ^/.well-known/host-meta.json /public.php?service=host-meta-json last;
rewrite ^/.well-known/webfinger /public.php?service=webfinger last;
add_header Strict-Transport-Security "max-age=15768000; includeSubDomains; preload;";

location = /.well-known/carddav {
	return 301 $scheme://$host/remote.php/dav;
}

location = /.well-known/caldav {
	return 301 $scheme://$host/remote.php/dav;
}

location = /robots.txt {
	allow all;
	log_not_found off;
	access_log off;
}

# Enable gzip but do not remove ETag headers

gzip_vary on;

}

location ~ ^\/(?:updater|ocs-provider)(?:$|\/) {
	try_files $uri/ =404;
	index index.php;
}

# Adding the cache control header for js and css files

location ~ \.(?:css|js|woff2?|svg|gif)$ {
	try_files $uri /index.php$request_uri;
	add_header Cache-Control "public, max-age=15778463";
	add_header X-Content-Type-Options nosniff;
	add_header X-XSS-Protection "1; mode=block";
	add_header X-Robots-Tag none;
	add_header X-Download-Options noopen;
	add_header X-Permitted-Cross-Domain-Policies none;
	add_header Referrer-Policy no-referrer;
}

location ~ \.(?:png|html|ttf|ico|jpg|jpeg)$ {
	try_files $uri /index.php$request_uri;
}

 

NGINX-Settings:

 

 

In PHP settings we set the version to 7.2.x or 7.3.x and enter the following value under OPEN-Base-Dir:

 

{WEBSPACEROOT}{/}{:}{TMP}{/}:/dev/urandom:/proc/meminfo

 

in section disable_functions you have to delete opcache_get_status and insert none.

Don’t forget to adjust the upload_max_filesize and post_max_size values.

as example we can use the following values if you want to upload files not greater than 2 GB:

 

 

Then set pm to dynamic and adjust, as example:
 

 

At the bottom of the page under Additional configuration instructions, we set following parameters:

 

opcache.enable_cli=1
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.memory_consumption=128
opcache.save_comments=1
opcache.revalidate_freq=1

[php-fpm-pool-settings]
env[PATH] = /usr/local/bin:/usr/bin:/bin

 

Among the hosting settings, we have to set the 301 redirect (http to https) and run php set to FPM Application served by nginx:

 

 

Prepare Database

 

Add a database within the subdomain:

 

 

and accept or adjust the following settings and write them down for later use:

 

 

Finish the installation

 

Via the web browser, we call our Nextcloud-Webinstaller and complete the Installation now:

https://nextcloud.your-domain.tld/setup-nextcloud.php

In the next step, we enter a single „.“ into the field:

And after another click on „Next“, we should see the success of the installation:

The next step is to adjust the settings:

 

If we are logged in, we have to edit the config.php in config directory in Plesk via File Manager and insert the following block for the cache (if redis is installed):

 

'memcache.distributed' => '\\OC\\Memcache\\Redis',
'memcache.local' => '\OC\Memcache\Redis',
'memcache.locking' => '\\OC\\Memcache\\Redis',
'redis' => array(
'host' => 'localhost',
'port' => 6379,
),

 

If we have ssh-access (as root or Plesk-User), then we can create a CRON job (adjust user):

 
as root:

sudo crontab -u admin -e

 

as Plesk-User:

crontab -e

and enter the following line (customize domain and subdomain):

 

*/15 * * * * php -f /var/www/vhosts/domain.tld/nextcloud.domain.tld/cron.php

 

Sometimes it is also possible to add a task via the GUI:

Otherwise, we use an external WebCron service, for example EasyCron.

The URL that needs to be called is:

 

https://nextcloud.domain.tld/nextcloud/cron.php

 
Among the basic settings, we check Nextcloud for errors and subsequently also in Plesk in the subdomain under logs.

you should see a warning for bigint indentifiers

because of this you have to execute the following command in your shell:

sudo -u admin php /var/www/vhosts/your-domain.tld/nextcloud.your-domain.tld/occ db:convert-filecache-bigint

After this errors or warnings should no longer be displayed.

If you have problems or questions, suggestions, don’t hesitate to contact me.

See you and happy Nextclouding 🙂
