disable default webpage

Once it is done, you shall disable Apache’s default welcome page.

[root@rmohan.com ~]# sed -i ‘s/^/#&/g’ /etc/httpd/conf.d/welcome.conf

Also, prevent the Apache web server from displaying files within the web directory.

[root@rmohan.com ~]# sed -i “s/Options Indexes FollowSymLinks/Options FollowSymLinks/” /etc/httpd/conf/httpd.conf

After that, start and enable the Apache web server.

[root@rmohan.com ~]# systemctl start httpd.service
[root@rmohan.com ~]# systemctl enable httpd.service
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
Setup WebDAV

For Apache, there are three WebDAV-related modules which will be loaded by default when an Apache web server is getting started.

[root@rmohan.com ~]# httpd -M | grep dav
dav_module (shared)
dav_fs_module (shared)
dav_lock_module (shared)

Next, create a dedicated directory for WebDAV:

[root@rmohan.com ~]# mkdir /var/www/html/webdav
[root@rmohan.com ~]# chown -R apache:apache /var/www/html
[root@rmohan.com ~]# chmod -R 755 /var/www/html

For security purposes, you need to create a user account.

[root@rmohan.com ~]# htpasswd -c /etc/httpd/.htpasswd user1
New password:
Re-type new password:
Adding password for user user1

And also, you need to modify the owner and permissions in order to enhance security

[root@rmohan.com ~]# chown root:apache /etc/httpd/.htpasswd
[root@rmohan.com ~]# chmod 640 /etc/httpd/.htpasswd

Once it is done, you need to create a VirtialHost for WebDAV.

[root@rmohan.com ~]# vi /etc/httpd/conf.d/webdav.conf
DavLockDB /var/www/html/DavLock
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html/webdav/
ErrorLog /var/log/httpd/error.log
CustomLog /var/log/httpd/access.log combined
Alias /webdav /var/www/html/webdav
<Directory /var/www/html/webdav>
DAV On
AuthType Basic
AuthName “webdav”
AuthUserFile /etc/httpd/.htpasswd
Require valid-user
</Directory>
</VirtualHost>

Once the VirtualHost is configured, you need to restart Apache to put your changes into effect.

[root@rmohan.com ~]# systemctl restart httpd.service

Test the functionality of the WebDAV server from a local machine. In order to take advantage of WebDAV, you need to use a qualified client. For example, you can install a program called cadaver on a CentOS 7 desktop

[root@rmohan.com ~]# yum install cadaver
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* base: mirror.dhakacom.com
* epel: mirror2.totbb.net
* extras: mirrors.viethosting.com
* updates: centos-hn.viettelidc.com.vn

cadaver.x86_64 0:0.23.3-9.el7

Complete!

Having cadaver installed, use the following command to access the WebDAV server.

[root@rmohan.com ~]# cadaver http://192.168.7.234/webdav/
Authentication required for webdav on server `192.168.7.234′:
Username: user1
Password:
dav:/webdav/>

In the cadaver shell, you can upload and organize files as you wish. Here are some examples. To upload a local file

dav:/webdav/> put /root/Desktop/rmohan.com.txt
Uploading /root/Desktop/rmohan.com.txt to `/webdav/rmohan.com.txt’: succeeded.

To create a directory “dir1” on the WebDAV server

dav:/webdav/> mkdir dir

To quit the cadaver shell

dav:/webdav/> exit
Connection to `192.168.7.234′ closed.
If you want to learn more about cadaver, you can look up the cadaver manual in the Bash shell. With this, the tutorial on setting up a WebDAV Server Using Apache on CentOS 7 comes to an end.
