一.添加master 部署高可用k8s架构 1.拷贝/opt/kubernetes目录到新的master上(注意如果新机上部署了etcd要排除掉) scp -r /opt/kubernetes/ root@192.168.24.12:/opt/ 2.拷贝主件服务 scp /usr/lib/systemd/system/{kube-apiserver.service,kube-controller-manager.service,kube-scheduler.service} root@192.1…

一.安装nginx 我们这边默认安装的nginx的是1.12.2的版本,所以我们需要安装1.16.1版本的nginx的,才好,所以我们这边先更新yum源,步骤如下: 1.添加yum源: [root@shtw-nk08 sbin]# cd /etc/yum.repos.d/ [root@shtw-nk08 sbin]# vim nginx.repo [nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/cen…

一.MHA的简单介绍MHA是由perl语言编写的,用外挂脚本的方式实现mysql主从复制的高可用性.MHA可以自动检测mysql是否宕机,如果宕机,在10-30s内完成new master的选举,应用所有差异的binlog日志到所有slave,将所有的slave切换到新的master上来.MHA除了自动检测mysql是否宕机,还能够交互式的切换master,在日常的数据库维护中,这个功能还是挺有用的.由于MHA本身只负责数据库主从的切换,但是应用程序并不知道数据库的master变了.针对这种情况…
