1. 编辑本机IP地址

cd /etc/sysconfig/network-scripts
ifcfg-eth0
…
…
vi ifcfg-eth0

如下为教学示例

如下为本机配置

TYPE=“Ethernet”
PROXY_METHOD=“none”
BROWSER_ONLY=“no”
BOOTPROTO=“static”
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”
DEVICE=“ens33”
ONBOOT=“yes”
IPADDR=192.168.121.101
NETMASK=255.255.255.0
GATEWAY=192.168.121.2
DNS1=114.114.114.114
DNS2=8.8.8.8

2. 删除 70**** 文件

暂时不清楚是什么逻辑，20201116删除后可以正常连接，待验证

oot root 628 Nov 16 05:37 70-persistent-ipoib.rules
[[email protected] rules.d]# rm 70-persistent-ipoib.rules
rm: remove regular file ‘70-persistent-ipoib.rules’? n

0:02:c9:03:00:31:78:f2", NAME=“mlx4_ib3”

删除当前目录==/etc/udev/rules.d==
下的这个文件
70-persistent-ipoib.rules

3 /etc/sysconfig/network

有主机名称，改为自定义的文字

NETWORKING=yes
HOSTNAME=node01

各个ip

重启电脑

init 6

禁用启用VMnet8

很重要的一点，原理未知，待查！！！

配置VMware 使用静态ip地址

关闭防火墙

Linux下打开和关闭防火墙bai
1.及时生效,重启后复原du
关闭:service iptables stop
开启:service iptalbes start
查看状态:service iptables status
(关闭状态的话会提zhi示firewal is not running)

2.非及时性生效,重启后永久性dao生效

关闭:chkconfig iptbales off
开启:chkconfig iptables on
查看状态:chkconfig iptables --list

3. 关闭firewall防火墙
   [[email protected] html]# systemctl stop firewalld #停止firewall防火墙
   [[email protected] html]# systemctl disable firewalld #禁止firewall开机启动
   [[email protected] html]# systemctl status firewalld

system status firewalld
