Linux – BASP

BASP (Broadcom Advanced Server Program)
Step 0:簡介
Step 1:安裝
Step 2:設定
Step 3:SLB with 負載平衡(loading balance) +容錯(Failover/Failback)
Step 4:SLB without 容錯(fallback)
Step 5:SLB with VLAN

Step 0:簡介

BASP是由 Broadcom這幾提供的 Bonding(可以將不同的網路 port 變成同一個 port)，除了提供負載平衡(load-balancing)，容錯(fault-tolerance)的功能外，還能有 VLAN(Switch 的功能，主要是將實體的裝置分割成不同區塊,可以減少封包的碰撞) 的功能。

Step 1:安裝

系統預設沒有安裝這個套件,我們必須到 http://www.broadcom.com 下載.

[root@unsvr ~]# cp basplnx-6.3.1.i386.tgz /tmp
[root@unsvr ~]# tar xvfz basplnx-6.3.1.i386.tgz
[root@unsvr ~]# cd basplnx-6.3.1
[root@unsvr basplnx-6.3.1]# make install
[root@unsvr basplnx-6.3.1]depmod –a
[root@unsvr basplnx-6.3.1]insmod basp

Step 2:設定

[root@unsvr ~]# cd /etc/sysconfig/network-scripts
[root@unsvr ~]# vi ifcfg-eth0
DEVICE= eth0
BOOTPROTO=static
ONBOOT=yes

[root@unsvr ~]# vi ifcfg-eth0
DEVICE= eth1
BOOTPROTO=static
ONBOOT=yes

Step 3:SLB with 負載平衡(loading balance) +容錯(Failover/Failback)

高可用性 系統資源（例如磁碟或 IP 位址）會自動地從故障的伺服器移轉至提供服務的伺服器。這種過程稱作 錯誤移轉 （Failover）。
容錯回復 當故障的伺服器修復並且重回線上時，會自動地重新平衡叢集中的工作負載。這被稱為 錯誤回復 （Failback）。

[root@unsvr ~]# cd /etc/basp
[root@unsvr basp]# cp sample/team-sample /etc/basp
[root@unsvr basp]# vi team-sample
TEAM_ID=0
TEAM_TYPE=0
TEAM_NAME=TeamSample
# Set to 1 to enable the probe packets feature. Set to 0 or remove to
# disable probe packets
LIVE_LINK_ENABLE=0
# 1st physical interface in the team
TEAM_PA0_NAME=eth0
TEAM_PA0_ROLE=0
# 2nd physical interface in the team
TEAM_PA1_NAME=eth1
TEAM_PA1_ROLE=0
# 1st virtual interface in the team
TEAM_VA0_NAME=sw0
TEAM_VA0_VLAN=0
TEAM_VA0_IP=192.2.1.10
TEAM_VA0_NETMASK=255.255.255.0
[root@unsvr basp]# /etc/init.d/basp start

or

[root@unsvr basp]# baspif /etc/basp/team-sample start
[root@unsvr basp]# baspif /etc/basp/team-sample stop

Step 4:SLB without 容錯(fallback)

[root@unsvr basp]# cd /etc/basp
[root@unsvr basp]# cp sample/team-sample /etc/basp
[root@unsvr basp]# cp sample/team-sample /etc/basp
[root@unsvr basp]# vi team-sample
TEAM_TYPE=3
TEAM_NAME=TeamSample
# Set to 1 to enable the probe packets feature. Set to 0 or remove to
# disable probe packets
LIVE_LINK_ENABLE=0
# 1st physical interface in the team
TEAM_PA0_NAME=eth0
TEAM_PA0_ROLE=0
# 2nd physical interface in the team
TEAM_PA1_NAME=eth1
TEAM_PA1_ROLE=0
# 1st virtual interface in the team
TEAM_VA0_NAME=sw0
TEAM_VA0_VLAN=0
TEAM_VA0_IP=192.2.1.10
TEAM_VA0_NETMASK=255.255.255.0
[root@unsvr basp]# /etc/init.d/basp start

or

[root@unsvr basp]# baspif /etc/basp/team-sample start
[root@unsvr basp]# baspif /etc/basp/team-sample stop
