حل مشكلة whm Could not open /etc/resolv.conf: Permission denied
CentOS 7.5 - name server entry in resolv.conf
resolv.config readonly

عند استلام السيرفر لاول مرة فى حالة انه centos 7 هيتم استخدام الاوامر التالية

حيث عند عمل تعديل لـ ملف resolv.conf لا يقبل

لذا يتم اعطاء الصلاحيات مع استخدام اخر كود فى هذه الموضوع

Just change permissions temporarily:

كود:

---

sudo chmod 744 /etc/resolv.conf

---

Add nameservers of your VPN provider by editing the file with text editor:

كود:

---

nameserver ip_of_nameserver_one
nameserver ip_of_nameserver_two

---

Save the file,then revert permissions.

كود:

---

sudo chmod 644 /etc/resolv.conf
sudo chattr +i /etc/resolv.conf

---

The last command will add immutable bit, so the file doesn't get overwritten. After you set immutable bit, even the root account will not be able to write to the file. If you wish to edit the file again latter on, and remove immutable bit, use this command:

كود:

---

sudo chattr -i /etc/resolv.conf

---
