linux升级nacos2.2.2版本，MySQL做持久化
下载最新版本包
点击此处下载最新的资源包上传到服务区
执行安装
- 停止已有的服务，备份现有nacos包（可忽略）
- 解压nacos-server-2.2.2.tar.gz到对应目录，修改配置文件application.properties
nacos默认使用derby做持久化，或者想使用mysql做持久化，根据下面配置文件修改对应位置，注意：db.user.0和db.passowrd.0和nacos登陆界面用户名和密码要保持一致，否则会启动失败

5.相关问题说明
报类似错：Unknown column ‘encrypted_data_key‘ in ‘field list
看提示是数据表缺少encrypted_data_key字段，那就手动为据表添加该字段为保证用户敏感配置数据的安全，Nacos 提供了配置加密的新特性。降低了用户使用的风险，也不需要再对配置进行单独的加密处理。
数据库表 config_info、config_info_beta、his_config_info中需要新增字段 encrypted_data_key ，用来存储每一个配置项加密使用的秘钥。新版本的默认创建表的sql中已经添加该字段。
ALTER TABLE config_info ADD COLUMN `encrypted_data_key` text NOT NULL COMMENT '秘钥';ALTER TABLE his_config_info ADD COLUMN `encrypted_data_key` text NOT NULL COMMENT '秘钥';ALTER TABLE config_info_beta ADD COLUMN `encrypted_data_key` text NOT NULL COMMENT '秘钥';报类似错：Error creating bean with name ‘authFilterRegistration‘ defined in class path resource
解决方法：启动按单机模式启动即可
sh startup.sh -m standalone
