一、安裝keepalived 1.2.2
yum -y install gcc make openssl openssl-devel wget kernel-devel
mkdir -p /usr/local/src/hasoft
cd /usr/local/src/hasoft
wget
tar -zxvf keepalived-1.2.2.tar.gz
cd keepalived-1.2.2
./configure --prefix=/usr/local/keepalived --with-kernel-dir=/usr/src/kernels/2.6.18-238.19.1.el5-i686/
make && make install
二、整理管理檔案
cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/
三、服務設定開機啟動
chkconfig keepalived on
或者echo "/usr/local/keepalived/sbin/keepalived" >> /etc/rc.local
四、配置
1. 主-備模式
節點a 192.168.0.11 (主節點),節點b 192.168.0.12(備用節點),虛擬ip(對外提供服務的ip 192.168.0.200,192.168.0.201)
節點a上的配置檔案/usr/local/keepalived/etc/keepalived/keepalived.conf:
global_defs
notification_email_from [email protected] #傳送通知郵件
smtp_server localhost
smtp_connect_timeout 30
router_id nodea #路由id,唯一標識本節點
} vrrp_instance vi_1
virtual_ipaddress
} 節點b上的配置檔案/usr/local/keepalived/etc/keepalived/keepalived.conf:
global_defs
notification_email_from [email protected] #傳送通知郵件
smtp_server localhost
smtp_connect_timeout 30
router_id nodeb #路由id,唯一標識本節點
} vrrp_instance vi_1
virtual_ipaddress
} 2. 雙主模式
雙主模式允許兩台機器均處於工作狀態並互相作為備份。
搭建keepalived雙主模式的要素：
1. 必須有兩個虛擬ip, 分別繫結至兩個節點上
2. 每個節點作為某個虛擬ip的主節點，並同時作為另外乙個虛擬ip的備用節點。
3. 當某個節點產生故障時，兩個虛擬ip自動繫結至正常節點上
也就是說，兩個節點的配置應該是交叉的，對同個虛擬ip，交叉互為主備。
節點a上的配置檔案/usr/local/keepalived/etc/keepalived/keepalived.conf:
global_defs
notification_email_from [email protected]
smtp_server localhost
smtp_connect_timeout 30
router_id nodea
} vrrp_instance vi_1
virtual_ipaddress
} vrrp_instance vi_2
virtual_ipaddress
} 節點b上的配置檔案/usr/local/keepalived/etc/keepalived/keepalived.conf:
global_defs
notification_email_from [email protected]
smtp_server localhost
smtp_connect_timeout 30
router_id nodeb
} vrrp_instance vi_1
virtual_ipaddress
} vrrp_instance vi_2
virtual_ipaddress
} 五、啟動keepalived服務
service keepalived start
或者/etc/init.d/keepalived start
或者/usr/local/keepalived/sbin/keepalived
#需要分別啟動nodea,nodeb上的keepalived服務
六、驗證服務
1. 執行命令ip addr|a|address檢視eth0上的ip
2. 停止nodea或nodeb, 檢查ip是否能夠成功漂移到正常的節點
