1. VM網(wǎng)絡(luò)設(shè)置

點(diǎn)擊NAT設(shè)置
圖2
記住網(wǎng)關(guān)和子網(wǎng)ip秽荞，后面會(huì)用
2. CentOs網(wǎng)絡(luò)設(shè)置
[root@localhost download]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# ls
ifcfg-ens33 ifdown-eth ifdown-post ifdown-Team ifup-aliases ifup-ipv6 ifup-post ifup-Team init.ipv6-global
ifcfg-lo ifdown-ippp ifdown-ppp ifdown-TeamPort ifup-bnep ifup-isdn ifup-ppp ifup-TeamPort network-functions
ifdown ifdown-ipv6 ifdown-routes ifdown-tunnel ifup-eth ifup-plip ifup-routes ifup-tunnel network-functions-ipv6
ifdown-bnep ifdown-isdn ifdown-sit ifup ifup-ippp ifup-plusb ifup-sit ifup-wireless
用vim打開 ifcfg-ens33
修改我圈中的這幾項(xiàng)寝杖，網(wǎng)關(guān)和子網(wǎng)ip與之前一一對(duì)應(yīng)起來。
重啟網(wǎng)絡(luò)模塊
service network restart
3. 檢測(cè)網(wǎng)絡(luò)是否配置成功
ping百度
[root@localhost network-scripts]# ping baidu.com
PING baidu.com (220.181.57.216) 56(84) bytes of data.

查看ip
此命令需要先安裝net工具包yum install net-tools -y
[root@localhost network-scripts]# ifconfig

更換yum源
安裝vim
yum install vim -y
4. SSH工具連接
安裝openssh-server
yum install openssh-server -y
開放22端口或者關(guān)閉防火墻(二選一)
開放端口
firewall-cmd --zone=public --add-port=22/tcp --permanent
其中：
–zone #作用域
–add-port=80/tcp #添加端口，格式為：端口/通訊協(xié)議
–permanent #永久生效萄传，沒有此參數(shù)重啟后失效
關(guān)閉防火墻
//臨時(shí)關(guān)閉
systemctl stop firewalld
//禁止開機(jī)啟動(dòng)
systemctl disable firewalld
關(guān)閉SELinux
#臨時(shí)關(guān)閉
setenforce 0
#永久關(guān)閉
vi /etc/selinux/config
開始連接
我用的是XShell工具
什么？ssh還連接不上？
在VM里還原默認(rèn)網(wǎng)絡(luò)配置龄句，然后注意把NAT模式的子網(wǎng)ip也對(duì)應(yīng)做修改。
