KeepAlived服务正在运行，但不执行check haproxy脚本
KeepAlived服务正在运行，但不执行check haproxy脚本
提问于 2022-05-15 18:40:13
我已经配置了一个故障转移负载均衡器，以便它在我的主服务器崩溃时充当备份。因此，我已经设置了一个保存器，当它无法找到运行在其他机器上的服务HAProxy时，就将浮动虚拟IP地址切换到另一台机器。conf文件中提到的IP地址出现在我的eth1接口上。

pidof pidof haproxy输出
主要的
root@ubuntu-s-1vcpu-1gb-blr1-01:~# pidof haproxy 726 719
次要
root@ubuntu-s-2vcpu-4gb-blr1-01:~# pidof haproxy 328842 328841
注意:我手动运行了/etc/备存/master.sh.sh脚本，它成功地运行了。
EDIT1:即使我使用pidof -s haproxy，它也不起作用

重新安装KeepAlived包解决了我的问题。
移除保存的：
sudo apt-get remove -y keepalived
sudo apt-get remove --auto-remove -y keepalived安装KEEPALIVED
sudo apt-get update
sudo apt-get install -y keepalived页面原文内容由Server Fault提供。腾讯云小微IT领域专用引擎提供翻译支持
