初期設定　（ファイアウォールの停止とSELinux (Security-Enhanced Linux)を無効にする。）

初期設定として

ファイアウォールの停止とSELinux (Security-Enhanced Linux)を無効にする。

１．ファイアウォール

ネットワーク内の上位にファイアウォールがおり、ホスト側で必要ない場合は停止しておきます。

# systemctl stop firewalld
# systemctl disable firewalld

1 2	# systemctl stop firewalld # systemctl disable firewalld

２．SELinux (Security-Enhanced Linux)

SELinux (Security-Enhanced Linux)を無効にする場合は以下のように設定します。

#vi /etc/selinux/config
     1
     2  # This file controls the state of SELinux on the system.
     3  # SELINUX= can take one of these three values:
     4  #     enforcing - SELinux security policy is enforced.
     5  #     permissive - SELinux prints warnings instead of enforcing.
     6  #     disabled - No SELinux policy is loaded.
     7  SELINUX=disabled
          // disabledに変更
     8  # SELINUXTYPE= can take one of three two values:
     9  #     targeted - Targeted processes are protected,
    10  #     minimum - Modification of targeted policy. Only selected processes are protected.
    11  #     mls - Multi Level Security protection.
    12  SELINUXTYPE=targeted
    13
# reboot
    // 一旦再起動

#vi /etc/selinux/config
