How to Install and Configure Nextcloud on CentOS 7 / RHEL 7

Install and Configure Nextcloud on CentOS / RHEL 7

Nextcloud is functionally very similar to the widely used Dropbox, with the primary functional difference being that Nextcloud is free and open-source, and thereby allowing anyone to install and operate it without charge on a private server. 

In contrast to proprietary services like Dropbox, the open architecture allows adding additional functionality to the server in form of so-called applications.

Nextcloud is an actively maintained fork of ownCloud.

Some of the Key features of Nextcloud are listed below:

• File access & sharing 
• Security & control 
• Mobile & desktop clients  
• External storage 
• Calendar & Contacts  
• Secure audio & video calls
• Collabora Online Office
• Videos of Nextcloud in action

yum install wget bzip2 -y

After that download the file from nextcloud official website - ClickHere

wget https://download.nextcloud.com/server/releases/nextcloud-9.0.53.tar.bz2

When your download is complete just extract the downloaded "nextcloud-9.0.53.tar.bz2" file to Web Server document root (/var/www/html) using bellow command.

tar -jxpvf nextcloud-9.0.53.tar.bz2 -C /var/www/html/

Open the ports in firewall for nextcloud (or you can stop the firewall) using bellow command.

[root@nextcloud ~]# firewall-cmd --permanent --zone=public --add-service=http
[root@nextcloud ~]# firewall-cmd --permanent --zone=public --add-service=https
[root@nextcloud ~]# firewall-cmd --reload

In my Case I am putting selinux in disabled mod  using below command you can use it as permissive mod

setenforce 0

For Permanently disabled edit the following line and find this line"SELINUX=enforcing" to disabled

vi /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted
