Hal-Hal Yang Harus Dilakukan Setelah Install CentOS Server

1. Setting IP Static (jika belum)

# system-config-network

Dengan perintah diatas anda dapat menyeting ip ,gateway dan dns

2.Matikan Firewall-tui

# system-config-firewall-tui

Anda Harus mendisable firewall default nya
contoh:

[root@server1 ~]# iptables -L

Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

3. Matikan SELinux

#vi /etc/selinux/config

 script nya :

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled                                             <<-----menjadi -="" are="" disable="" level="" mls="" multi="" of="" one="" processes="" protected="" protection.="" security="" selinuxtype="targeted</pre" take="" targeted="" these="" two="" values:="">

 4.Samakan Hostname
Cek dengan perintah seperti dibawah

root@server1 ~ # hostname

server1.com
root@server1 ~ # hostname -f
server1.com.com

jika belum sama seperti di atas coba

#vi /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
192.168.12.50   server1.com     server1                                         <<---tambahkan ::1="" localhost.localdomain="" localhost6.localdomain6="" localhost6="" localhost="" pre="">


#Reboot
 5.Update system


#yum update
