1、安装keepalived（yum）
- keepalived主网站不提供任何Linux发行版的软件包，它只提供源代码和代码库。
- 大多数Linux发行版都提供keepalived包作为主线包，包维护人员在维护和报告有关它的问题方面做得很好。
1.1、安装前的准备
1、时间同步
#安装ntpdate yum install ntpdate -y #同步时间 ntpdate ntp1.aliyun.com
2、关闭防火墙
#查看防护墙状态 systemctl status firewalld.service #关闭防火墙 systemctl stop firewalld.service systemctl disable firewalld.service
3、禁用selinux
#查看selinux的状态 getenforce #临时有效 setenforce 0 #永久有效。改系统文件/etc/sysconfig/selinux，然后重启机器 sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
4、开启网路接口的多播功能
#开启用于集群服务的网络接口的多播功能(MULTICAST状态) ip link set multicast on dev ens33
1.2、安装keepalived
1、安装keepalived
- CentoS 6.4版本之后，keepalived服务由base仓库提供。
yum install keepalived
2、查看keepalived服务的主要文件
]# rpm -ql keepalived /etc/keepalived/keepalived.conf #主配置文件 /etc/sysconfig/keepalived #Unit File的环境文件 /usr/lib/systemd/system/keepalived.service #Unit File /usr/sbin/keepalived #主程序文件 ......

2.2、安装keepalived
1、安装依赖
yum install gcc openssl-devel libnl libnl3-devel -y
2、安装keepalived
]# wget https://www.keepalived.org/software/keepalived-2.1.5.tar.gz --no-check-certificate ]# tar zvfx keepalived-2.1.5.tar.gz ]# cd keepalived-2.1.5/ ]# mkdir -pv /apps/keepalived-2.1.5 ]# ./configure --prefix=/apps/keepalived-2.1.5 ]# make && make install
- 问题：在执行make的时候由很多警告信息（不知道是否有影响）
