本文档详细介绍了在CentOS7上安装keepalived 2.0.18的步骤，包括解压安装包、解决编译警告、配置系统服务以及启动和验证虚拟IP的设置。在编译过程中遇到IPv6不支持的问题，通过指定配置解决了警告。

参考：慕课网

（1）将安装包传到 /home/software 并进行解压

tar -zxvf keepalived-2.0.18.tar.gz

（2）编译运行

 cd keepalived-2.0.18/

./configure --prefix=/usr/local/keepalived --sysconf=/etc

出现警告：*** WARNING - this build will not support IPVS with IPv6. Please install libnl/libnl-3 dev libraries to support IPv6 with IPVS

yum -y install libnl libnl-devel

然后重新执行 ./configure --prefix=/usr/local/keepalived --sysconf=/etc

make && make install

（3）查看keepalived安装目录和配置文件路径

[root@localhost keepalived-2.0.18]# whereis keepalived
keepalived: /etc/keepalived /usr/local/keepalived

（4）添加到systemd管理

# 将初始化脚本拷贝到系统初始化目录下
cp /home/software/keepalived-2.0.18/keepalived/etc/init.d/keepalived /etc/init.d/

# 将keepalived配置文件拷贝到etc下
cp /home/software/keepalived-2.0.18/keepalived/etc/sysconfig/keepalived /etc/sysconfig/

# 重新加载
systemctl daemon-reload

（5）修改 keepalived.conf（只有修改了才可以正常启动）

vi /etc/keepalived/keepalived.conf

全部内容如下

! Configuration File for keepalived

global_defs {
   # 路由id：当安装keepalived节点主机的标识符，全局唯一
   #router_id LVS_DEVEL
   router_id keep_171
}

# 
vrrp_instance VI_1 {
    # 表示的状态，当前的171为nginx的主节点，MASTER/BACKUP
    state MASTER
    # 当前实例绑定的网卡
    #interface eth0
    interface ens33
    # 保证主备节点一致
    virtual_router_id 51
    # 优先级/权重，谁的优先级高，在MASTER挂掉，就成为MASTER
    priority 100
    # 主备之间同步检查的时间间隔，默认1s
    advert_int 1
    # 认证授权的密码，防止非法节点的进入
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    # 虚拟ip
    virtual_ipaddress {
       # 192.168.200.16
       # 192.168.200.17
       # 192.168.200.18
	192.168.1.161
    }
}

（6）启动
