1、官方下载
wget http://www.keepalived.org/software/keepalived-XXXX.tar.gz
2、解压，编译安装
tar zxvf keepalived-XXXX.tar.gz ./configure --prefix=/usr/local/keepalived --with-kernel-dir=/usr/src/kernels/2.6.XXXXXXXX/ make && make install cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/ cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/ mkdir /etc/keepalived cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/ cp /usr/local/keepalived/sbin/keepalived /usr/sbin/ service keepalived start
在使用./configure 时，出现了以下错误：
checking openssl/ssl.h usability... no checking openssl/ssl.h presence... no checking for openssl/ssl.h... no configure: error: !!! OpenSSL is not properly installed on your system. !!! !!! Can not include OpenSSL headers files. !!!
解决方法：安装openssl和openssl-devel包，然后从新编译配置文件
[root@wlm keepalived-1.3.2]# yum install openssl openssl-devel [root@wlm keepalived-1.3.2]# ./configure --prefix=/usr/local/keepalived --with-kernel-dir=/usr/src/kernels/2.6.XXXXXXXX/ Keepalived configuration ------------------------ Keepalived version : 1.3.2 Compiler : gcc Preprocessor flags : Compiler flags : -Wall -Wunused -Wstrict-prototypes -Wextra -g -O2 Linker flags : Extra Lib : -ldl -lssl -lcrypto Use IPVS Framework : Yes IPVS use libnl : No IPVS syncd attributes : No IPVS 64 bit stats : No fwmark socket support : Yes Use VRRP Framework : Yes Use VRRP VMAC : Yes Use VRRP authentication : Yes With ip rules/routes : Yes SNMP vrrp support : No SNMP checker support : No SNMP RFCv2 support : No SNMP RFCv3 support : No DBUS support : No SHA1 support : No Use Debug flags : No Stacktrace support : No Memory alloc check : No libnl version : None Use IPv4 devconf : No Use libiptc : No Use libipset : No init type : systemd Build genhash : Yes Build documentation : No
3、配置
Master与Backup 的配置文件
Master：
! Configuration File for keepalived
global_defs {
notification_email {
15251076067@163.com
}
notification_email_from king_819@163.com
smtp_server smtp.163.com
smtp_connect_timeout 30
router_id LVS_DEVEL
}
# VIP1
vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 51
mcast_src_ip 192.168.18.211
priority 100
advert_int 5
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.18.200
}
}BackUP：
! Configuration File for keepalived
global_defs {
notification_email {
15251076067@163.com
}
notification_email_from king_819@163.com
smtp_server smtp.163.com
smtp_connect_timeout 30
router_id LVS_DEVEL
}
# VIP1
vrrp_instance VI_1 {
state BACKUP
interface eth0
virtual_router_id 51
mcast_src_ip 192.168.18.212
priority 90
advert_int 5
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.18.200
}
}以下是在CentOS上使用yum安装配置：
1、安装
yum install keepalived -y
2、MASTER和BACKUP配置
MASTER
[root@wlm ~]# vim /etc/keepalived/keepalived.conf
! Configuration File for keepalived
global_defs {
notification_email {
acassen@firewall.loc
failover@firewall.loc
sysadmin@firewall.loc
}
notification_email_from Alexandre.Cassen@firewall.loc
smtp_server 192.168.200.1
smtp_connect_timeout 30
router_id LVS_DEVEL
}
vrrp_instance VI_1 {
state MASTER # 配置为主
interface eno16777736 # 设置网卡
virtual_router_id 51 # 虚拟路由ID，全局唯一
priority 100 # 优先级，权重值
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
10.10.10.50 # IP地址
}
}BACKUP
! Configuration File for keepalived
global_defs {
notification_email {
871703234@qq.com
}
notification_email_from 871703234@qq.com
smtp_server smtp.qq.com
smtp_connect_timeout 30
router_id LVS_DEVEL
}
vrrp_instance VI_1 {
state BACKUP
interface eno16777736
virtual_router_id 51
priority 90
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
10.10.10.50
}
}3、验证
两台重启服务
[root@wlm ~]# systemctl restart keepalived.service
使用ip add sh命令查看，在主的上面
[root@wlm keepalived]# ip add sh 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:a3:4b:3e brd ff:ff:ff:ff:ff:ff inet 10.10.10.10/24 brd 10.10.10.255 scope global eno16777736 valid_lft forever preferred_lft forever inet 10.10.10.50/32 scope global eno16777736 valid_lft forever preferred_lft forever inet6 fe80::20c:29ff:fea3:4b3e/64 scope link valid_lft forever preferred_lft forever
使用systemctl stop keepalived.service,VIP会自动切换到备用的上面去。
