vmware虚拟机和centos连接不上

1. VM网络设置

 点击NAT设置 

记住网关和子网ip，后面会用

2. CentOs网络设置

[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打开 ifcfg-ens33

 修改我圈中的这几项，网关和子网ip与之前一一对应起来。

重启网络模块

service network restart

3. 检测网络是否配置成功

ping百度

1. [root@localhost network-scripts]# ping baidu.com

2. PING baidu.com (220.181.57.216) 56(84) bytes of data.

3. 64 bytes from 220.181.57.216 (220.181.57.216): icmp_seq=1 ttl=128 time=18.5 ms

4. 64 bytes from 220.181.57.216 (220.181.57.216): icmp_seq=2 ttl=128 time=18.7 ms

5. 64 bytes from 220.181.57.216 (220.181.57.216): icmp_seq=3 ttl=128 time=17.7 ms

查看ip

此命令需要先安装net工具包yum install net-tools -y

1. [root@localhost network-scripts]# ifconfig

2. ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

3. inet 192.168.27.132 netmask 255.255.255.0 broadcast 192.168.27.255

4. inet6 fe80::99b3:c79:5377:c3fe prefixlen 64 scopeid 0x20<link>

5. ether 00:0c:29:7b:59:07 txqueuelen 1000 (Ethernet)

更换yum源

CentOS 7.x 安装阿里yum源

安装vim

yum install vim -y

4. SSH工具连接

安装openssh-server

yum install openssh-server -y

开放22端口或者关闭防火墙(二选一)

开放端口

1. firewall-cmd --zone=public --add-port=22/tcp --permanent

2. 其中：

3. –zone #作用域

4. –add-port=80/tcp #添加端口，格式为：端口/通讯协议

5. –permanent #永久生效，没有此参数重启后失效

6. 复制代码

关闭防火墙

1. //临时关闭

2. systemctl stop firewalld

3. //禁止开机启动

4. systemctl disable firewalld

5. 复制代码

关闭SELinux

1. #临时关闭

2. setenforce 

开始连接

我用的是XShell工具

什么？ssh还连接不上？

在VM里还原默认网络配置，然后注意把NAT模式的子网ip也对应做修改。
