OpenWebUi update so quickly so have to write a post to record it. I deploy it with docker with default set. so this article is show the process in the openWebUI deploied by docker. ssh the server execute the command sudo docker run --rm --volume /var/run/docker.sock:/var/run/docker.sock containrrr/watchtower --run-once open-webui execute the command sudo docker image ls if you find the image list contain two open-webui .and one' tag is <none> then update success. if your server disk space is small like me .you can delete the docker image to save the disk space used the command sudo docker rmi <IMAGE ID>. please notice used the image id to prevent to delete the docker image that just updated image.
本篇文章主要是介绍基于IP的哈希的负载均衡与故障绑定的设定与检查。 一.负载均衡的设定 1.同一台ESXI，上面有两台虚拟机，当然虚拟机的IP地址不相同。这两台虚拟机连接到同一个端口组。该端口组所在的标准虚拟交换机有两个上行链路并且启用了基于IP的哈希的负载均衡与故障绑定的设定。如下图： 2.该端口组也设置了基于IP的哈希的负载均衡与故障绑定。如下图： 3.完成设置后，大概的简略图如下所示： 二.负载均衡的验证 特别声明： 1.必须使用以下的方法验证，才能验证出来。 就是要虚拟机和实体机不同的主机之间互相访问。 2.通过ESXI主机上的监控可以发现，流量分别走了不同的网卡。如下图： 这里要特别注意。 但网络上说，不同的主机同时访问同一台主机的时候，也会走不同的上行链路，我这边没有验证成功。又有说，从外部主机访问内部主机时，是外部主机主导的上行链路的选择，所以我从一台虚拟机去同时访问两台外部主机时，发现也没有分别走不同的上行链路。
