How to Setup a WebDAV Server Using Apache on CentOS 7<\/strong><\/p>\n

CentOS Linux Guides Server Apps Web Servers<\/strong><\/p>\n

WebDAV stands for “Web-based Distributed Authoring and Versioning”. It’s an extension of the HTTP protocol that allows users to manage and share files stored on a WebDAV-enabled web server.<\/p>\n

This tutorial will show you how to setup a WebDAV server using Apache on a Vultr CentOS 7 server instance.<\/p>\n

Prerequisites
\nA Vultr CentOS 7 server instance.
\nA non-root sudo user. You can learn more about how to create a sudo user in this Vultr tutorial.
\nStep one: Update the system
\nsudo yum install epel-release
\nsudo yum update -y
\nsudo shutdown -r now
\nAfter the reboot, use the same sudo user to log in.<\/p>\n

Step two: Install Apache
\nInstall Apache using YUM:<\/p>\n

sudo yum install httpd
\nDisable Apache’s default welcome page:<\/p>\n

sudo sed -i ‘s\/^\/#&\/g’ \/etc\/httpd\/conf.d\/welcome.conf
\nPrevent the Apache web server from displaying files within the web directory:<\/p>\n

sudo sed -i “s\/Options Indexes FollowSymLinks\/Options FollowSymLinks\/” \/etc\/httpd\/conf\/httpd.conf
\nStart the Apache web server:<\/p>\n

sudo systemctl start httpd.service
\nsudo systemctl enable httpd.service
\nStep three: Setup WebDAV
\nFor Apache, there are three WebDAV-related modules which will be loaded by default when a Apache web server getting started. You can confirm that with this command:<\/p>\n

sudo httpd -M | grep dav
\nYou should be presented with:<\/p>\n

dav_module (shared)
\ndav_fs_module (shared)
\ndav_lock_module (shared)
\nNext, create a dedicated directory for WebDAV:<\/p>\n

sudo mkdir \/var\/www\/html\/webdav
\nsudo chown -R apache:apache \/var\/www\/html
\nsudo chmod -R 755 \/var\/www\/html
\nFor security purposes, you need to create a user account, say it is “user001”, to access the WebDAV server, and then input your desired password. Later, you will use this user account to log into your WebDAV server.<\/p>\n

sudo htpasswd -c \/etc\/httpd\/.htpasswd user001
\nModify the owner and permissions in order to enhance security:<\/p>\n

sudo chown root:apache \/etc\/httpd\/.htpasswd
\nsudo chmod 640 \/etc\/httpd\/.htpasswd
\nStep four: Create a virtual host for WebDAV
\nsudo vi \/etc\/httpd\/conf.d\/webdav.conf
\nPopulate the file with:<\/p>\n

DavLockDB \/var\/www\/html\/DavLock
\n<VirtualHost *:80>
\nServerAdmin webmaster@localhost
\nDocumentRoot \/var\/www\/html\/webdav\/
\nErrorLog \/var\/log\/httpd\/error.log
\nCustomLog \/var\/log\/httpd\/access.log combined
\nAlias \/webdav \/var\/www\/html\/webdav
\n<Directory \/var\/www\/html\/webdav>
\nDAV On
\nAuthType Basic
\nAuthName “webdav”
\nAuthUserFile \/etc\/httpd\/.htpasswd
\nRequire valid-user
\n<\/Directory>
\n<\/VirtualHost>
\nSave and quit:<\/p>\n

:wq!
\nRestart Apache to put your changes into effect:<\/p>\n

sudo systemctl restart httpd.service
\nStep five: Modify firewall rules
\nsudo firewall-cmd –zone=public –permanent –add-service=http
\nsudo firewall-cmd –reload
\nStep six: Test the functionality of the WebDAV server from a local machine
\nIn 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:<\/p>\n

sudo yum install cadaver
\nHaving cadaver installed, use the following command to access the WebDAV server:<\/p>\n

cadaver http:\/\/<your-server-ip>\/webdav\/
\nUse the username “user001” and the password you setup earlier to log in.<\/p>\n

In the cadaver shell, you can upload and organize files as you wish. Here are some examples.<\/p>\n

To upload a local file “\/home\/user\/abc.txt” to the WebDAV server:<\/p>\n

dav:\/webdav\/> put \/home\/user\/abc.txt
\nTo create a directory “dir1” on the WebDAV server:<\/p>\n

dav:\/webdav\/> mkdir dir1
\nTo quit the cadaver shell:<\/p>\n

dav:\/webdav\/> exit
\nIf you want to learn more about cadaver, you can look up the cadaver manual in the Bash shell:<\/p>\n

man cadaver
\nor<\/p>\n

cadaver -h<\/p>\n

 <\/p>\n

 <\/p>\n

Once it is done, you shall disable Apache’s default welcome page.<\/p>\n

[root@linuxhelp ~]# sed -i ‘s\/^\/#&\/g’ \/etc\/httpd\/conf.d\/welcome.conf<\/p>\n

Also, prevent the Apache web server from displaying files within the web directory.<\/p>\n

[root@linuxhelp ~]# sed -i “s\/Options Indexes FollowSymLinks\/Options FollowSymLinks\/” \/etc\/httpd\/conf\/httpd.conf<\/p>\n

After that, start and enable the Apache web server.<\/p>\n

[root@linuxhelp ~]# systemctl start httpd.service
\n[root@linuxhelp ~]# systemctl enable httpd.service
\nCreated symlink from \/etc\/systemd\/system\/multi-user.target.wants\/httpd.service to \/usr\/lib\/systemd\/system\/httpd.service.
\nSetup WebDAV<\/p>\n

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

[root@linuxhelp ~]# httpd -M | grep dav
\ndav_module (shared)
\ndav_fs_module (shared)
\ndav_lock_module (shared)<\/p>\n

Next, create a dedicated directory for WebDAV:<\/p>\n

[root@linuxhelp ~]# mkdir \/var\/www\/html\/webdav
\n[root@linuxhelp ~]# chown -R apache:apache \/var\/www\/html
\n[root@linuxhelp ~]# chmod -R 755 \/var\/www\/html<\/p>\n

For security purposes, you need to create a user account.<\/p>\n

[root@linuxhelp ~]# htpasswd -c \/etc\/httpd\/.htpasswd user1
\nNew password:
\nRe-type new password:
\nAdding password for user user1<\/p>\n

And also, you need to modify the owner and permissions in order to enhance security<\/p>\n

[root@linuxhelp ~]# chown root:apache \/etc\/httpd\/.htpasswd
\n[root@linuxhelp ~]# chmod 640 \/etc\/httpd\/.htpasswd<\/p>\n

Once it is done, you need to create a VirtialHost for WebDAV.<\/p>\n

[root@linuxhelp ~]# vi \/etc\/httpd\/conf.d\/webdav.conf
\nDavLockDB \/var\/www\/html\/DavLock
\n<VirtualHost *:80>
\nServerAdmin webmaster@localhost
\nDocumentRoot \/var\/www\/html\/webdav\/
\nErrorLog \/var\/log\/httpd\/error.log
\nCustomLog \/var\/log\/httpd\/access.log combined
\nAlias \/webdav \/var\/www\/html\/webdav
\n<Directory \/var\/www\/html\/webdav>
\nDAV On
\nAuthType Basic
\nAuthName “webdav”
\nAuthUserFile \/etc\/httpd\/.htpasswd
\nRequire valid-user
\n<\/Directory>
\n<\/VirtualHost><\/p>\n

Once the VirtualHost is configured, you need to restart Apache to put your changes into effect.<\/p>\n

[root@linuxhelp ~]# systemctl restart httpd.service<\/p>\n

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<\/p>\n

[root@linuxhelp ~]# yum install cadaver

\ncadaver.x86_64 0:0.23.3-9.el7<\/p>\n

Complete!<\/p>\n

Having cadaver installed, use the following command to access the WebDAV server.<\/p>\n

[root@linuxhelp ~]# cadaver http:\/\/192.168.7.234\/webdav\/
\nAuthentication required for webdav on server `192.168.7.234′:
\nUsername: user1
\nPassword:
\ndav:\/webdav\/><\/p>\n

In the cadaver shell, you can upload and organize files as you wish. Here are some examples. To upload a local file<\/p>\n

dav:\/webdav\/> put \/root\/Desktop\/linuxhelp.txt
\nUploading \/root\/Desktop\/linuxhelp.txt to `\/webdav\/linuxhelp.txt’: succeeded.<\/p>\n

To create a directory “dir1” on the WebDAV server<\/p>\n

dav:\/webdav\/> mkdir dir<\/p>\n

To quit the cadaver shell<\/p>\n

dav:\/webdav\/> exit
\nConnection to `192.168.7.234′ closed.
\nIf 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
