Steps to Install NextCloud on Cloud Server (Nginx, Redis Cache)

NextCloud is like your own Dropbox. Possibly you know about OwnCloud. That OwnCloud’s founder have quit to start up a new fork and a new company called NextCloud. OwnCloud had 2 types of softwares – free and paid. NextCloud is different than OwnCloud at some points, has no paid software but paid hosting. Here Are the Steps to Install NextCloud on Cloud Server With Nginx Server, Redis Cache, 2 FA, HTTPS.

NextCloud Official Resources

You’ll not need the resources at all, yet we are giving the appropriate resources for advance configuration, optimisation, bug reporting etc :

https://github.com/nextcloud/server
https://docs.nextcloud.com/server/11/admin_manual/installation/index.html

Steps to Install NextCloud on Cloud Server

We are using Ubuntu 16.04 LTS as server OS. Follow this guide up to step 2.3 on the table of contents to create a LEMP server. If you are using CentOS, simply use CentMinMod script to create LEMP server. Also create a database, database user following that guide.

So we are starting with Nginx, MySQL installed on server. First install Redis :

apt install redis-server php7.0-redis
nano /etc/redis/redis.conf

1 2	apt install redis-server php7.0-redis nano /etc/redis/redis.conf

Change the maximum memory size. Run these commands :

service redis-server restart
service nginx restart
service php7.0-fpm restart
redis-cli monitor

1

2

3

4

service redis-server restart

service nginx restart

service php7.0-fpm restart

redis-cli monitor

We need to add binlog-format = mixed on my.cnf :

nano /etc/mysql/my.cnf 
# in the [mysqld] block add
# binlog-format = mixed 
service mysql restart

1

2

3

4

nano /etc/mysql/my.cnf

# in the [mysqld] block add

# binlog-format = mixed

service mysql restart

Our default config file i.e. /etc/nginx/sites-enabled/default should look like this :

server {
listen 80;
server_name example.com;
return 301 https://example.com$request_uri;
location '/.well-known/acme-challenge' {

unzip nextcloud-11.0.0.zip

mv nextcloud example.com

sudo chown -R www-data:www-data /var/www/html/example.com

Now after restarting Nginx, open your domain/subdomain on browser which is example.com here, there will be a web GUI based wizard.

Steps to Install NextCloud on Cloud Server (Nginx, Redis Cache)

We will now configure Redis as the cache server for Nextcloud :

nano /var/www/html/example.com/config/config.php
# populate with this data. Add the following lines above the last line with `);` :
'memcache.distributed' => '\OC\Memcache\Redis',
'memcache.local' => '\OC\Memcache\Redis',
'filelocking.enabled' => 'true',
'memcache.locking' => '\OC\Memcache\Redis',
'redis' => array(
     'host' => 'localhost',
     'timeout' => 0,
     'dbindex' => 0,
     'port' => 6379,
     ),

'filelocking.enabled' => 'true',

'memcache.locking' => '\OC\Memcache\Redis',

'redis' => array(

'host' => 'localhost',

'timeout' => 0,

'dbindex' => 0,

'port' => 6379,

),

Nextcloud will give you option on Web GUI to encrypt the data and Two Factor Authentication.
