4. attr directive in rpm spec

attr directive in rpm spec


  • I understand what %attr and %defattr are doing in general.

    What I am not clear on is what %attr does to sub files and folder when a directory is specified.

    Does it apply it to all the files and folders recursively, or does it apply it to only the top level folder.

    I am working on my install for NextCloud on CentOS and because they do not seem to have the clean RPM posted anywhere, I am trying to replicate what they have listed in their github repo for it.

    Specifically here:

    %files 
%defattr(0640,root,%{nc_group},0750)
%attr(0755,root,%{nc_group}) %{nc_dir}
%attr(0755,%{nc_user},%{nc_group}) %{nc_dir}/occ
%attr(0750,%{nc_user},%{nc_group}) %{nc_dir}/apps
%attr(0750,%{nc_user},%{nc_group}) %{nc_dir}/assets
%attr(0750,%{nc_user},%{nc_group}) %{nc_dir}/updater
%attr(0775,%{nc_user},%{nc_group}) %{nc_data_dir}
%attr(0775,%{nc_user},%{nc_group}) %{nc_config_dir}

    That %defattr means all files are chmod 0640 while all directories are chmod 0750 and everything is chown root:apache

    It seems that the directories subsequently specified are chown apache:apache and some are chmod 755. But are those supposed to be recursive?

  • This is my not cleaned up nor annotated notes so far to give perspective.

    yum -y update
yum install -y wget nano firewalld
yum install -y epel-release
systemctl start firewalld
systemctl enable firewalld


Install packages
yum -y install httpd php-gd php-pdo php-pear php-mbstring php-xml php-pear-Net-Curl php-mcrypt php-intl php-ldap php-smbclient php-imap php-mysql php-pear-MDB2 php-pear-MDB2-Driver-mysqli bzip2


Create directory
mkdir -p /var/www/html/nextcloud

Get NextCloud
wget https://download.nextcloud.com/server/releases/nextcloud-10.0.1.tar.bz2

Extract NextCloud
tar xvf nextcloud-10.0.1.tar.bz2 -C /var/www/html

Create directories not created by extract
mkdir -p /var/www/html/nextcloud/data
mkdir -p /var/www/html/nextcloud/etc
mkdir -p /var/www/html/nextcloud/assets

wget -O /etc/httpd/conf.d/nextcloud.conf https://raw.githubusercontent.com/nextcloud/server-packages/master/centos/nextcloud.conf

default everything to root:apache
chown -R root:apache /var/www/html/nextcloud/.

set default directory and file permissions
find /var/www/html/nextcloud -type d -exec chmod 0750 {} \;
find /var/www/html/nextcloud -type f -exec chmod 0640 {} \;

relax restrictions for selected folders and files that need more access
chmod 0755 /var/www/html/nextcloud


change ownership of folders and files

  • getting back to this setup now.

    I would assume that the way the %attr works based on reading it is that all files in the listed folder get the listed permissions.
