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`
6.   
7.  `复制代码`

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)`
6.  `RX packets 288077 bytes 405462136 (386.6 MiB)`
7.  `RX errors 0 dropped 0 overruns 0 frame 0`
8.  `TX packets 14968 bytes 2189388 (2.0 MiB)`
9.  `TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0`
10.  
11. `lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536`
12. `inet 127.0.0.1 netmask 255.0.0.0`
13. `inet6 ::1 prefixlen 128 scopeid 0x10<host>`
14. `loop txqueuelen 1000 (Local Loopback)`
15. `RX packets 83 bytes 8297 (8.1 KiB)`
16. `RX errors 0 dropped 0 overruns 0 frame 0`
17. `TX packets 83 bytes 8297 (8.1 KiB)`
18. `TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0`
19. `复制代码`

更换yum源

[CentOS 7.x 安装阿里yum源][CentOS 7.x _yum]

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。
