1、VMwareは仮想マシンを作成するには
2、インストールCentOS7
システム言語を選択
パーティション計画は、デフォルトの自動パーティショニングを選択し、手動で分割することができます:
ネットワークとホスト名を設定します。
ここで指定した名前ホスト:centos7を、ネットワーク接続を開くと、システムはインストールが完了した後に設定された他のネットワークパラメータのを待ちます。
日付と時刻を設定します。
システムのインストールを開始します。
rootユーザのパスワードを設定して、パスワードが単純すぎている場合、あなたは2回連続完了左上隅をクリックする必要があります。
システムのインストールが完了するのを待ちます
システムのインストールが完了し、再起動
3、設定
3.1ネットワーク設定
CentOS7では、インストールを最小限にifconfigコマンドを使用することはできません、カード情報を表示するコマンドです
ip addr
ネットワークカードのどこに「ens33」名、IPアドレスやその他の情報を変更します
vi /etc/sysconfig/network-scripts/ifcfg-ens33
実際の状況の内容を変更します。
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static #启用静态ip地址
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=8d497804-9ffa-4edc-951a-5ddd8d2ed504
DEVICE=ens33
ONBOOT=yes #自动启用网络连接
IPADDR0=192.168.0.201 #IP地址
PREFIXO0=24 #子网掩码
GATEWAY0=192.168.0.1 #网关
DNS1=192.168.0.1 #DNS
変更した後の良好な保存して終了し、ネットワークを再起動し、ネットワーク接続が正常であるかどうかをテストします:
[root@centos7 ~]# service network restart
Restarting network (via systemctl): [ OK ]
[root@centos7 ~]# ping www.baidu.com

3.2インストールのifconfigコマンド
ifconfigコマンドが含まれているコンポーネントを参照してください。
yum provides ifconfig
或
yum whatprovides ifconfig
ifconfigコマンドは、ネットのツールに依存して、インストール
yum install -y net-tools
インストールのvimエディタ3.3
yum install -y vim-enhanced
3.4 wgetのインストール
yum install -y wget
3.5閉じるSELinuxの
SELinuxの設定ファイルの編集
vim /etc/selinux/config
2行をコメントアウトし、コードの最後の行を加えた1
#SELINUX=enforcing
#SELINUXTYPE=targeted
SELINUX=disabled
保存して、設定が有効になっている閉じて、それはシステムを再起動するのが最善である、後で再起動することができます
setenforce 0
閉じるCentOSの3.6は、ファイアウォール、ファイアウォールが付属して、iptablesの有効
# 停止firewall
[root@centos7 /]# systemctl stop firewalld
# 关闭firewall自动启动
[root@centos7 /]# systemctl disable firewalld.service
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
iptablesファイアウォールをインストールします。
yum install -y iptables-services
デフォルトの設定ファイルを使用してiptablesは、あなたがこのプロファイルにルールを増やすことができます
[root@centos7 ~]# vim /etc/sysconfig/iptables
# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter

iptablesは、再起動、およびカイから起動するように項目を追加、ステータスのiptablesを表示します
[root@centos7 ~]# systemctl restart iptables.service
[root@centos7 ~]# systemctl enable iptables.service
Created symlink from /etc/systemd/system/basic.target.wants/iptables.service to /usr/lib/systemd/system/iptables.service.
