zstack 版本升级

概述

今天看了下官网的zstack的安装镜像，发现2018-3-24有一次发布，因为本地是测试环境，而且我没有尝试过升级zstack，所以就打算升级一下zstack

升级前要知道的事情

首先官网上说zstack是支持两种升级方式，一种是增量升级一种是离线升级，增量方便，虽然不知道两种方式区别是什么，但是我选择了增量升级，可能就是软件源一个用线上，一个就是直接用本地的iso了吧，而且在升级前要对数据库做一个备份。还要知道一点的是，你只需要升级你的管理节点就好了，计算节点会自动升级的

备份数据库

ssh进管理节点输入下面命令dump出数据库
zstack-ctl dump_mysql

[root@MiWiFi-R1CM-srv ~]# zstack-ctl dump_mysql 
Backup mysql successfully! You can check the file at /var/lib/zstack/mysql-backup/zstack-backup-db-2018-03-26_14-22-38.gz

升级

接着wget下安装包
wget http://cdn.zstack.io/product_downloads/zstack-enterprise/enterprise2.3/ZStack-installer-2.3.0.495.bin
下载完成输入下面命令直接升级
bash ZStack-installer-2.3.0.495.bin -u
记住全程要可以连上互联网，不然使用离线升级，整个升级过程很流畅，速度也挺快，可能是因为版本之间变化不大的缘故吧

[root@MiWiFi-R1CM-srv ~]# bash ZStack-installer-2.3.0.495.bin -u

而且升级的时候我还开着一些虚拟机，也没有出现一些异常
