Você pode querer executar
fixfiles -R openvpn restore
Um ls -alZ deve fornecer algo assim (mostrando que seus arquivos estão no contexto correto do selinux agora):
[root@server openvpn]# ls -alZ /etc/openvpn/
drwxr-xr-x. root root system_u:object_r:openvpn_etc_t:s0 .
drwxr-xr-x. root root system_u:object_r:etc_t:s0 ..
drwxr-xr-x. root root unconfined_u:object_r:openvpn_etc_t:s0 certs
-rw-r--r--. root root unconfined_u:object_r:openvpn_etc_t:s0 dh2048.pem
drwxr-xr-x. root root unconfined_u:object_r:openvpn_etc_t:s0 easy-rsa
-rw-------. root root unconfined_u:object_r:openvpn_etc_rw_t:s0 ipp.txt
-rw-------. root root unconfined_u:object_r:openvpn_etc_t:s0 ta.key
-rw-------. openvpn openvpn unconfined_u:object_r:openvpn_etc_t:s0 server.conf
Se você tiver uma declaração como
status openvpn-status.log
no seu arquivo de configuração openvpn, você pode notar que o servidor ainda não será iniciado. Uma espiada no /var/log/audit/audit.log irá revelar
type=AVC msg=audit(1413580155.710:1265): avc: denied { write } for pid=19725 comm="openvpn" name="openvpn-status.log" dev="dm-1" ino=54153273 scontext=system_u:system_r:openvpn_t:s0 tcontext=unconfined_u:object_r:openvpn_etc_t:s0 tclass=file
Mudar o contexto deste arquivo para rw faz o truque:
chcon -t openvpn_etc_rw_t openvpn-status.log
e
[root@server openvpn]# ls -alZ openvpn-status.log
-rw-------. root root unconfined_u:object_r:openvpn_etc_t:s0 openvpn-status.log
se tornará
-rw-------. root root unconfined_u:object_r:openvpn_etc_rw_t:s0 openvpn-status.log
Depois da chamada
service openvpn@server start
funcionou perfeitamente.
[root@server openvpn]# service openvpn@server status
