8. After the installation process finishes and Alfresco services are started issue the below commands in order to open the following firewall ports to allow external hosts in your network to connect to the web application.

# firewall-cmd --add-port=8080/tcp -permanent
# firewall-cmd --add-port=8443/tcp -permanent
# firewall-cmd --add-port=7070/tcp -permanent
# firewall-cmd --reload

In case you need to add other firewall rules to open ports in order to access custom Alfresco services issue the ss command to get a list of all the services running on your machine.

# ss -tulpn

9. To access Alfresco web services, open a browser and use the following URLs (replace the IP Address or domain accordingly). Login with admin user and the password configured for Admin through the installation process.

http://IP-or-domain.tld:8080/share/

Step 2: Configure Nginx as Frontend Web Server for Alfresco

10. In order to install Nginx server on the system, first add Epel Repositories on CentOS/RHEL by issuing the below command:

# yum install epel-release

11. After Epel repos are added into the system proceed with Nginx web server installation by issuing the following command:

# yum install nginx [On RHEL/CentOS Systems]
# apt-get install nginx [On Debian/Ubuntu Systems] 

12. On the next step open Nginx configuration file from /etc/nginx/nginx.conf with a text editor and make the following changes:

location / {
proxy_pass http://127.0.0.1:8080;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
Configure Nginx for Alfresco

Configure Nginx for Alfresco

Go below and make sure you comment the second location statement by placing a # in front of the following lines:

#location / {
# }

13. After you’re done, save and close Nginx configuration file and restart daemon to reflect change by issuing the following command:

# systemctl restart nginx.service

14. In order to access Alfresco web interface add a new firewall rule to open port 80 on your machine and navigate to the below URL. Also, make sure Selinux policy is disabled on RHEL/CentOS systems.

# firewall-cmd --add-service=http -permanent
# firewall-cmd --reload
# setenforce 0

To completely disable Selinux policy on the system, open /etc/selinux/config file and set the line SELINUX from enforcing to disabled.

15. Now you can access Alfresco through Nginx.

 http://IP-or-domain.tld/share/ http://IP-or-domain.tld/alfresco/
http://IP-or-domain.tld/alfresco/webdav 

15. In case you want to securely visit Alfresco web interface through Nginx proxy with SSL, create a Self-Signed Certificate for Nginx on /etc/nginx/ssl/ directory and fill the certificate with your custom settings as illustrated on below screenshot:

# mkdir /etc/nginx/ssl
# cd /etc/nginx/ssl/
# openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout alfresco.key -out alfresco.crt
Create SSL Certificate for Alfresco

Create SSL Certificate for Alfresco

Pay attention to Certificate Common Name to match your domain hostname.

17. Next, open Nginx configuration file for editing and add the following block before the last closing curly bracket (the } symbol).

# vi /etc/nginx/nginx.conf

Nginx SSL block excerpt:

server {
listen 443;
server_name _;
ssl_certificate /etc/nginx/ssl/alfresco.crt;
ssl_certificate_key /etc/nginx/ssl/alfresco.key;
ssl on;
ssl_session_cache builtin:1000 shared:SSL:10m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
ssl_prefer_server_ciphers on;
access_log /var/log/nginx/ssl.access.log;
location / {
proxy_pass http://127.0.0.1:8080;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
## This is the last curly bracket before editing the file. }

18. Finally, restart Nginx daemon to apply changes, add a new firewall rule for 443 port.

# systemctl restart nginx
# firewall-cmd -add-service=https --permanent
# firewall-cmd --reload

and instruct the browser to your domain URL using the HTTPS protocol.

https://IP_or_domain.tld/share/
https://IP_or_domain.tld/alfresco/
Configure Alfresco as Domain

19. In order to enable Alfresco and Nginx daemons system-wide run the below command:

# systemctl enable nginx alfresco

That’s all! Alfresco offers integration with MS Office and LibreOffice via CIFs protocol providing a familiar workflow for users.
