|
|
|
|
* 从最新的nacos:nacos-server/latest 镜像以后,移除了数据库主从镜像,具体原因请参考[移除主从镜像配置](https://github.com/nacos-group/nacos-docker/wiki/%E7%A7%BB%E9%99%A4%E6%95%B0%E6%8D%AE%E5%BA%93%E4%B8%BB%E4%BB%8E%E9%95%9C%E5%83%8F%E9%85%8D%E7%BD%AE)
|
2021-06-30 01:53:58 +00:00
|
|
|
|
* 从Nacos 1.3.1版本开始,数据库存储已经升级到8.0, 并且它向下兼容
|
|
|
|
|
|
* 例子演示中使用的数据库是为了方便定制了官方Mysql镜像, 自动初始化的数据库脚本.
|
|
|
|
|
|
* 如果你使用自定义数据库, 第一次启动Nacos前需要手动初始化 [数据库脚本](https://github.com/alibaba/nacos/blob/develop/distribution/conf/nacos-mysql.sql) .

## 高级配置
|
|
|
|
|
|
|
|
|
|
|
|
如果上面的属性列表无法满足你的需求时,可以挂载`custom.properties`到`/home/nacos/init.d/` 目录,然后在里面像使用Spring Boot的`application.properties`文件一样配置属性, 并且这个文件配置的属性**优先级高于application.properties**
|
|
|
|
|
|
|
|
|
|
|
|
参考例子: [cluster-hostname.yaml](/example/cluster-hostname)

## Nacos + Grafana + Prometheus
|
|
|
|
|
|
|
|
|
|
|
|
使用参考：[Nacos monitor-guide](https://nacos.io/zh-cn/docs/monitor-guide.html)
|
|
|
|
|
|
|
|
|
|
|
|
**Note**: 当使用Grafana创建数据源的时候地址必须是: **http://prometheus:9090**
|
