linux中的keeplived源码装,keepalived源码安装及主备配置

发布时间：2025/3/20 linux 49 豆豆

生活随笔收集整理的这篇文章主要介绍了 linux中的keeplived源码装,keepalived源码安装及主备配置小编觉得挺不错的,现在分享给大家,帮大家做个参考.

keepavlied起初专门为LVS设计的，专门用来监控LVS集群系统中各个服务节点的状态，后来加入VRRP功能，因此除了配合LVS服务外，也可以作为其他服务(nginx，haproxy)的高可用软件。

keepalived服务两大用途：healthcheck 健康检查(针对RS) 、failover 高可用故障转移(主备)

keepalived的安装，主和备都需要安装

和LVS安装一样，最好也先给内核路径做一个软连接到/usr/src/linux[root@localhost ~]# ln -s /usr/src/kernels/2.6.32-573.8.1.el6.i686/ /usr/src/linux

[root@localhost ~]# cd /usr/local/src/

[root@localhost src]# wget [root@localhost src]# tar xf keepalived-1.1.19.tar.gz

[root@localhost src]# cd keepalived-1.1.19

[root@localhost keepalived-1.1.19]# ./configure

configure执行成功的结果：有3个Yes；支持IPVS框架，IPVS的同步支持，VRRP的框架支持；

Keepalived configuration

------------------------

Keepalived version : 1.1.19

Compiler : gcc

Compiler flags : -g -O2

Extra Lib : -lpopt -lssl -lcrypto

Use IPVS Framework : Yes

IPVS sync daemon support : Yes

Use VRRP Framework : Yes

Use Debug flags : No[root@localhost keepalived-1.1.19]# make

[root@localhost keepalived-1.1.19]# make install

配置keepalived[root@localhost keepalived-1.1.19]# cp /usr/local/etc/rc.d/init.d/keepalived /etc/init.d/

[root@localhost keepalived-1.1.19]# cp /usr/local/etc/sysconfig/keepalived /etc/sysconfig/

[root@localhost keepalived-1.1.19]# mkdir /etc/keepalived -p

[root@localhost keepalived-1.1.19]# cp /usr/local/etc/keepalived/keepalived.conf /etc/keepalived/

[root@localhost keepalived-1.1.19]# cp /usr/local/sbin/keepalived /usr/sbin/

[root@localhost keepalived-1.1.19]# /etc/init.d/keepalived start

主MASTER、备backup上配置文件：/etc/keepalived/keepalived.conf

主master配置：vrrp_instance VI_1 {

state MASTER

interface eth0

virtual_router_id 51

priority 150

advert_int 1

authentication {

auth_type PASS

auth_pass 1111

}

virtual_ipaddress {

192.168.20.100/24

}

备 backup 的配置:vrrp_instance VI_1 {

state BACKUP

interface eth0

virtual_router_id 51

priority 100
