【问题描述】：

目前，我正在尝试在我的机器上使用 NGINX 运行 KEEPALIVED。我的用例包括监控 NGINX 服务器的故障转移行为，因为任何一个实例都可能出现故障，我需要让其他实例处于活动状态来处理传入请求。

下面是我的keepalived.conf文件，

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    priority 100
     track_script {
            chk_http_port
        }
    virtual_ipaddress {
        10.100.160.143
    }
}

vrrp_script chk_http_port {
        script "pidof nginx"
        interval 2

}

以下是我在位置 /var/logs/messages 遇到的错误

Keepalived_vrrp[33045]: Cant find interface eth0 for vrrp_instance VI_1 !!!

【解决方案1】：

您可能需要检查网络接口的名称。使用 ifconfig 列出所有网络接口，然后查找“eth0”。如果你的机器上不存在“eth0”，那么你需要在你的keepalived.conf中指定一个现有接口的名称
