parted -l

(3) fdisk /dev/sdb. d(delete) => n(new) => w(sync). When creating a partition, press enter to any quessions.

/dev/sdb1 /mnt/buffalo ext4    defaults        0 0

4. Creating subversion repositories

(1) Install subversion and mod_dav_svn which is Subversion Apache HTTP Server Module.

yum install mod_dav_svn subversion

(2) Create repositories.

cd /mnt/buffalo
mkdir ./svn_repo/rep1
mkdir ./svn_repo/rep2
svnadmin create ./svn_repo/rep1
svnadmin create ./svn_repo/rep2

(3) open repository configuration files by “vi /mnt/buffalo/svn_repo/rep1/conf/svnserve.conf” “vi /mnt/buffalo/svn_repo/rep2/conf/svnserve.conf” and add the following to [general] section.

anon-access = none
auth-access = write
authz-db = authz

(4) open authentication configuration files by “vi /mnt/buffalo/svn_repo/rep1/conf/authz” “vi /mnt/buffalo/svn_repo/rep2/conf/ authz” and add the followings.

[/]
* = rw

(5) create a httpd configuration file by “vi /etc/httpd/conf.d/subversion.conf” and add the followings.

LoadModule dav_svn_module     modules/mod_dav_svn.so
LoadModule authz_svn_module   modules/mod_authz_svn.so

<Location /svn>
  DAV svn
  SVNListParentPath on
  SVNParentPath /mnt/buffalo/svn_repo

  Satisfy Any
  AuthType Basic
  AuthName "Authorization Realm"
  AuthUserFile /mnt/buffalo/svn_repo/users
  Require valid-user
</Location>

(6) open a service configuration file “/etc/systemd/system/svnserve.service” and add the followings.

[Unit]

(9) allow http access to subversion.

firewall-cmd --zone=public --add-service=http --permanent
firewall-cmd --reload

(10) change owner of directory for subversion repository.

chown -R apache /mnt/buffalo/svn_repo
