oa服务器和网卡绑定问题

oa服务器和网卡绑定问题,第1张

oa服务器网卡需插上网线可以绑定。根据查询相关资料信息,oa服务器网卡必须插上网线,不允许使用无线网卡,使用有线网络连接,插上网线连通到局域网内,可以实现上网绑定。oa服务器是不需要显示屏的电脑,可以存放oa的程序。

系统版本

[root@ ~]# cat /etc/redhat-release

CentOS release 6.8 (Final)

[root@ ~]# uname -r

2.6.32-642.6.1.el6.x86_64

网卡说明

eth0   192.168.1.8(服务器外网卡)

eth1   服务器网卡(内网)

eth2   服务器网卡(内网)

[root@ ~]# /etc/init.d/iptables stop

[root@ ~]#  chkconfig iptables off

关闭selinux

[root@ ~]#setenforce 0

[root@ ~]#sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/‘ /etc/selinux/config

禁用NetworkManager

[root@ ~]# /etc/init.d/NetworkManager stop

Stopping NetworkManager daemon:           [  OK  ]

[root@ ~]# chkconfig NetworkManager off

[root@ ~]# /etc/init.d/network restart

双网卡绑定配置过程

[root@ ~]# cd /etc/sysconfig/network-scripts/

编辑eth1网卡

[root@ network-scripts]# cat >ifcfg-eth1 <>DEVICE=eth1

>ONBOOT=yes

>BOOTPROTO=none

>USERCTL=no

>MASTER=bind0

>EOF

编辑eth2网卡

[root@ network-scripts]# cat >ifcfg-eth2

ONBOOT=yes

BOOTPROTO=none

USERCTL=no

MASTER=bind0

EOF

编辑bind0网卡

[root@ network-scripts]# cat >ifcfg-bind0 <>DEVICE=bind0

>TYPE=Ethernet

>ONBOOT=yes

>BOOTPROTO=none

>IPADDR=10.0.0.8

>NETMASK=255.255.255.0

>GATEWAY=10.0.0.254

>IPV6INIT=no

>USERCTL=no

>EOF

配置bond参数

[root@ network-scripts]# cat >/etc/modprobe.conf <>alias bind0 bonding

>options bind0 miimon=100 mode=6

>EOF

加入开机自启动(/etc/rc.local)

[root@ network-scripts]# cat >>/etc/rc.local <>ifenslave bind0 eth1 eth2

>EOF

重启网络服务

[root@LVS-2 network-scripts]# service network restart

配置使绑定立即生效

[root@LVS-2 network-scripts]# ifenslave bind0 eth1 eth2

测试联通

[root@LVS-2 network-scripts]# ping 10.0.0.8

PING 10.0.0.8 (10.0.0.8) 56(84) bytes of data.

64 bytes from 10.0.0.8: icmp_seq=1 ttl=64 time=0.089 ms

64 bytes from 10.0.0.8: icmp_seq=2 ttl=64 time=0.046 ms

^C

--- 10.0.0.8 ping statistics ---

2 packets transmitted, 2 received, 0% packet loss, time 1921ms

rtt min/avg/max/mdev = 0.046/0.067/0.089/0.023 ms

此时会发现系统多一个网卡

[root@LVS-2 network-scripts]# ifconfig bind0

bind0

网络云中存储服务器网卡配置,配置网络平面网卡的绑定方式:通过源目的IP和端口负荷分担算法使绑定后的带宽高于单个网口的带宽。

存储服务器是指为特定目标而设计,因此配置方式也不同。它可能是拥有一点额外的存储,也可能拥有很大的存储空间的服务器。
