HBase集群绑定双网卡操作流程

问题导读

1.本文绑定双网卡包含了哪些步骤？

2.如何绑定双网卡？

一、停止集群服务

登录regionserver服务器，使用hadp用户操作

hbase-daemon.sh stopregionserver

hadoop-daemon.shstop tasktracker

hadoop-daemon.shstop datanode

/software/servers/zookeeper-3.4.3/bin/zkServer.shstop

二、绑定双网卡

登录regionserver服务器，使用root用户操作

1.备份

mkdir/etc/sysconfig/network-scripts/backup

mv/etc/sysconfig/network-scripts/ifcfg-eth0/etc/sysconfig/network-scripts/backup/

mv/etc/sysconfig/network-scripts/ifcfg-eth1/etc/sysconfig/network-scripts/backup/

mkdir/etc/modprobe.d/backup

cp /etc/modprobe.d/dist.conf/etc/modprobe.d/backup/

mkdir /etc/backup

cp /etc/rc.local/etc/backup

2.绑定双网卡，注意：一定要填写实际IP

shell# vim/etc/sysconfig/network-scripts/ifcfg-bond0

DEVICE=bond0

BOOTPROTO=static

ONBOOT=yes

IPADDR=172.XX.XX.XX

NETMASK=255.XX.XX.0

GATEWAY=172.XX.XX.XX   

USERCTL=no

TYPE=Ethernet

shell# vim/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=none

ONBOOT=yes

MASTER=bond0

SLAVE=yes

USERCTL=no

TYPE=Ethernet

shell# vim/etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1

BOOTPROTO=none

ONBOOT=yes

MASTER=bond0

SLAVE=yes

USERCTL=no

TYPE=Ethernet

shell# vim/etc/modprobe.d/dist.conf

alias bond0 bonding

options bond0 mode=0miimon=100

shell# vim/etc/rc.local

ifenslave bond0 eth0eth1

3.接入物理双网线

4.启动网卡检测状态

打开ilo进行操作

ifconfig eth0 up

ifconfig eth1 up

service networkrestart

ifconfig

5.回滚，在有必要时执行

rm -rf/etc/sysconfig/network-scripts/ifcfg-bond0

rm -rf/etc/sysconfig/network-scripts/ifcfg-eth0

rm -rf/etc/sysconfig/network-scripts/ifcfg-eth1

mv/etc/sysconfig/network-scripts/backup/ifcfg-eth0/etc/sysconfig/network-scripts/

mv/etc/sysconfig/network-scripts/backup/ifcfg-eth1/etc/sysconfig/network-scripts/

rmdir/etc/sysconfig/network-scripts/backup

rm -rf/etc/modprobe.d/dist.conf

mv/etc/modprobe.d/backup/dist.conf /etc/modprobe.d/

rmdir/etc/modprobe.d/backup

rm -rf /etc/rc.local

mv/etc/backup/rc.local /etc/

rmdir /etc/backup

三、启动集群服务

登录regionserver服务器，使用hadp用户操作

/software/servers/zookeeper-3.4.3/bin/zkServer.shstart

hadoop-daemon.shstart datanode

hadoop-daemon.shstart tasktracker

hbase-daemon.shstart regionserver
