Centos7设定网络
新安装的centos7，网络默认是不启动的，需要人为的手工修改配置文件，在这里把这个过程简要的记录一下。
- 设定ip地址与mac地址自定义
[root@web ~]# cd /etc/sysconfig/network-scripts [root@web network-scripts]# ls ifcfg-ens160 ifdown-ippp ifdown-routes ifup ifup-ipv6 ifup-ppp ifup-tunnel ifcfg-lo ifdown-ipv6 ifdown-sit ifup-aliases ifup-isdn ifup-routes ifup-wireless ifdown ifdown-isdn ifdown-Team ifup-bnep ifup-plip ifup-sit init.ipv6-global ifdown-bnep ifdown-post ifdown-TeamPort ifup-eth ifup-plusb ifup-Team network-functions ifdown-eth ifdown-ppp ifdown-tunnel ifup-ippp ifup-post ifup-TeamPort network-functions-ipv6 [root@web network-scripts]# more ifcfg-ens160 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no 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=ens160 UUID=028745b4-7fff-408f-ad04-e488da3c100a DEVICE=ens160 ONBOOT=yes BOOTPROTO=static IPADDR=172.17.109.3 PREFIX=24 GATEWAY=172.17.109.1 DNS1=172.17.5.1 MACADDR=18:a9:05:4e:ad:02 IPV6_PRIVACY=no
[root@web network-scripts]# systemctl restart network
- 配置静态路由
[root@web network-scripts]# vi route-ens160 [root@web network-scripts]# cat route-ens160 172.0.0.0/8 via 172.17.109.254 dev ens160 [root@web network-scripts]# systemctl restart network [root@web network-scripts]# ip route default via 172.17.109.1 dev ens160 proto static metric 100 172.0.0.0/8 via 172.17.109.254 dev ens160 proto static metric 100 172.17.109.0/24 dev ens160 proto kernel scope link src 172.17.109.3 metric 100
- 安装wget及设定阿里云yum镜象源
[root@web yum.repos.d]# yum install wget [root@web yum.repos.d]# wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo --2019-10-19 03:57:56-- http://mirrors.aliyun.com/repo/Centos-7.repo 正在解析主机 mirrors.aliyun.com (mirrors.aliyun.com)... 14.215.83.248, 113.96.109.96, 183.2.199.241, ... 正在连接 mirrors.aliyun.com (mirrors.aliyun.com)|14.215.83.248|:80... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK 长度：2523 (2.5K) [application/octet-stream] 正在保存至: “CentOS-Base.repo” 100%[==========================================================================>] 2,523 --.-K/s 用时 0s 2019-10-19 03:57:56 (147 MB/s) - 已保存 “CentOS-Base.repo” [2523/2523]) [root@web yum.repos.d]# yum makecache 已加载插件：fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com base | 3.6 kB 00:00:00 extras | 2.9 kB 00:00:00 updates | 2.9 kB 00:00:00 元数据缓存已建立 [root@web yum.repos.d]# yum update
- 安装 net-tools工具包后，可以使用netstat ifconfig 等网络命令
[root@web yum.repos.d]# yum install net-tools
- 启用firewalld防火墙
[root@web yum.repos.d]# systemctl enable firewalld [root@web yum.repos.d]# systemctl restart firewalld [root@web yum.repos.d]# firewall-cmd --list-all public (active) target: default icmp-block-inversion: no interfaces: ens160 sources: services: dhcpv6-client ssh ports: protocols: masquerade: no forward-ports: source-ports: icmp-blocks: rich rules:
