Eu tenho um CentOS 6.3 instalado com httpd em execução e vsftpd , mas não consigo equilibrar a permissão entre o usuário capaz de fazer o upload pelo ftp e o funcionamento de seu website.
O que eu faço:
I create a user with their home directory as '/home/username'
I create a sub folder called 'html' for their website
I chown their directory 'chown -R username:apache /home/username'
I chmod their directory 'chmod -R 750 /home/username'
I chcon their directory 'chcon -R -t httpd_sys_rw_content_t /home/username'
e seu site carrega muito bem, mas eles não conseguem fazer o ftp, mas se eu fizer o seguinte, eles poderão fazer o ftp, mas o site deles não carrega:
chcon -R -t user_home_dir_t /home/username
Se eu desabilitar o selinux, o usuário poderá fazer o ftp e o site ser carregado. então qual é a resposta para manter o selinux?
EDITAR
Curiosamente, segui os comentários de Michael abaixo e apenas corri restorecon e funcionou. Mas então eu reiniciei e agora vsftp está bem e httpd pode ler bem, mas o httpd não pode escrever.
Esta é minha ls -Z response
drwxr-x---. itmanx apache unconfined_u:object_r:user_home_dir_t:s0 itmanx

Nenhuma das opções acima.
Você defina os valores booleanos do SELinux que permitem que o httpd e o vsftpd acessem os diretórios home dos usuários.
setsebool -P httpd_enable_homedirs on
setsebool -P ftp_home_dir on
E depois de toda a sua brincadeira, você provavelmente deve corrigir os contextos de segurança confusos:
restorecon -r -v /home
