Nacos2.2.3之MySQL8.X持久化详细配置过程

1. 官网与下载

1. 官网

官网：https://nacos.io/zh-cn/docs/quick-start.html

Nacos文档：https://nacos.io/zh-cn/docs/quick-start.html

GitHub: https://github.com/alibaba/nacos/releases

2. Naocs是什么？

Nacos /nɑ:kəʊs/ 是 Dynamic Naming and Configuration Service的首字母简称，一个更易于构建云原生应用的动态服务发现、配置管理和服务管理平台。

Nacos 致力于帮助您发现、配置和管理微服务。Nacos 提供了一组简单易用的特性集，帮助您快速实现动态服务发现、服务配置、服务元数据及流量管理。

Nacos 帮助您更敏捷和容易地构建、交付和管理微服务平台。 Nacos 是构建以“服务”为中心的现代应用架构 (例如微服务范式、云原生范式) 的服务基础设施。

3. 下载

您可以在Nacos的release notes及博客中找到每个版本支持的功能的介绍及下载，截止到2024-03-02 官方推荐的稳定版本为2.2.3。

Github中下载

github直接下载链接

Windows: https://github.com/alibaba/nacos/releases/download/2.2.3/nacos-server-2.2.3.zip

Linux: https://github.com/alibaba/nacos/releases/download/2.2.3/nacos-server-2.2.3.tar.gz

2. 安装与持久化配置

1. Naocs默认使用的是嵌入式数据库derby；

2. 这里改为MySQL8作为持久化存储，Naocs也仅支持derby与mysql的，其他数据库存储需要自行编译支持，可参考nacos github中提供的插件来支持其他数据库的持久化

3. Nacos 从 2.2.0 版本开始,可通过 SPI 机制注入多数据源实现插件,并在引入对应数据源进行源码编译后,便可在 Nacos 启动时通过读取 application.properties 配置文件中 spring.datasource.platform 配置项选择加载对应多数据源插件；

4. 多数据源支持github地址：https://github.com/alibaba/nacos/blob/feature_multiple_datasource_support/README.md；

5. 下面以Windows版本为例配置Nacos2.2.3的持久化，Linux配置类似。

1. 解压安装

将下载后的nacos-server-2.2.3.zip解压到指定目录，如:H:\0002024CloudDeploy\nacos-2.2.3

2. 创建数据库

根据nacos-2.2.3/conf目录下的mysql-schema.sql创建数据库

1. 连接数据库

1. 打开命令行创建并进入到H:\0002024CloudDeploy\nacos-2.2.3\conf目录下；
2. 然后输入命令mysql -P 3307 -u root -p连接数据，注意这里使用 -P 3307指定连接MySQL的端口为3307，如果是默认的3306可以不写

H:\0002024CloudDeploy\nacos-2.2.3\conf>mysql -P 3307 -u root -p
Enter password: ******* # 这里输入密码回车，如下：
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 421
Server version: 8.0.29 MySQL Community Server - GPLCopyright (c) 2000, 2022, Oracle and/or its affiliates.Oracle is a registered trademark of Oracle Corporation and/or its
affiliates. Other names may be trademarks of their respective
owners.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.mysql>

2. 创建nacos数据库

mysql> create database nacos_config default character set utf8mb4 collate utf8mb4_general_ci;
Query OK, 1 row affected (0.01 sec)mysql>

3. 导入脚本

# 切换到 nacos_config数据库
mysql> use nacos_config;
Database changed
# 导入脚本
mysql> source mysql-schema.sql;
Query OK, 0 rows affected, 3 warnings (0.05 sec)Query OK, 0 rows affected, 3 warnings (0.04 sec)Query OK, 0 rows affected, 3 warnings (0.04 sec)Query OK, 0 rows affected, 3 warnings (0.04 sec)Query OK, 0 rows affected, 4 warnings (0.05 sec)Query OK, 0 rows affected, 9 warnings (0.04 sec)Query OK, 0 rows affected, 4 warnings (0.05 sec)Query OK, 0 rows affected, 9 warnings (0.04 sec)Query OK, 0 rows affected, 5 warnings (0.04 sec)Query OK, 0 rows affected (0.03 sec)Query OK, 0 rows affected (0.03 sec)Query OK, 0 rows affected (0.05 sec)Query OK, 1 row affected (0.01 sec)Query OK, 1 row affected (0.01 sec)mysql>

4. 查看表

nacos有12张表，如下

mysql> show tables;
+------------------------+
| Tables_in_nacos_config |
+------------------------+
| config_info            |
| config_info_aggr       |
| config_info_beta       |
| config_info_tag        |
| config_tags_relation   |
| group_capacity         |
| his_config_info        |
| permissions            |
| roles                  |
| tenant_capacity        |
| tenant_info            |
| users                  |
+------------------------+
12 rows in set (0.01 sec)mysql>

3. 持久化配置

1. nacos本身也是一个SpringBoot应用，所以配置在application.properties

2. nacos持久还配置在nacos-2.2.3/conf/application.properties中进行设置

1. application.properties修改前

application.properties中大概从33行开始，可以看到Config Module Related Configurations注释部分

#*************** Config Module Related Configurations ***************#
### If use MySQL as datasource:
### Deprecated configuration property, it is recommended to use `spring.sql.init.platform` replaced.
# spring.datasource.platform=mysql
# spring.sql.init.platform=mysql### Count of DB:
# db.num=1### Connect URL of DB:
# db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
# db.user.0=nacos
# db.password.0=nacos### Connection pool configuration: hikariCP

2. application.properties修改后

1. 将db.开头的相关注释去掉；

2. 注意spring.datasource.platform配置属性已弃用，建议使用spring.sql.init.platform替换。

#*************** Config Module Related Configurations ***************#
### If use MySQL as datasource:
### Deprecated configuration property, it is recommended to use `spring.sql.init.platform` replaced.
# spring.datasource.platform=mysql
spring.sql.init.platform=mysql### Count of DB:
# db.num=1
db.num=1
### Connect URL of DB:
db.url.0=jdbc:mysql://127.0.0.1:3307/my_nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=GMT%2B8&useSSL=false&useInformationSchema=true
db.user.0=root
db.password.0=你的密码### Connection pool configuration: hikariCP

3. 启动

Nacos默认是以集群的方式启动的，如果需要单机启动，则在命令行中指定-m standalone参数来启动

1. 启动

1. 打开命令行创口，进入nacos安装的bin目录下；
2. 执行命令startup.cmd -m standalone启动

1. 未配置MySQL8.X持久化前显示的是嵌入式存储

2. 配置MySQL8.X持久化后显示使用的是外部存储

2. 打开浏览器访问

特别注意：

2.2.2版本之前的Nacos默认控制台，无论服务端是否开启鉴权，都会存在一个登录页；这导致很多用户被误导认为Nacos默认是存在鉴权的。在社区安全工程师的建议下，Nacos自2.2.2版本开始，在未开启鉴权时，默认控制台将不需要登录即可访问，同时在控制台中给予提示，提醒用户当前集群未开启鉴权。

在用户开启鉴权后，控制台才需要进行登录访问。 同时针对不同的鉴权插件，提供新的接口方法，用于提示控制台是否开启登录页；同时在2.2.3版本后，Nacos可支持关闭开源控制台，并引导到用户自定义的Nacos控制台，详情可查看Nacos鉴权插件-服务端插件及控制台手册-关闭登录功能

1. Naocs2.2.2版本前需要登录

访问： http://localhost:8848/nacos ，需要登录

1. 输入用户名密码登录后如下：，默认用户名/密码：nacos/nacos
2. 登录后才进入到默认的配置管理列表页面中

2. nacos2.2.2版本之后无需登录

访问： http://localhost:8848/nacos，直接进入到配置列表页面中，可看到提示没有开启鉴权

如需要开启鉴权，点击下图红色区域的文档连接查看与配置即可

3. 关于Naocs鉴权

1. 关于nacos的鉴权，请查看官网 https://nacos.io/zh-cn/docs/v2/guide/user/auth.html
2. 鉴权配置不当，nacos无法启动

1. 开启鉴权访问

在application.properties中开启开启鉴权相关配置 ，如下

### If turn on auth system:
nacos.core.auth.system.type=nacos
# 1. 开启鉴权， 默认为 false 
nacos.core.auth.enabled=true ### ...
### 2. nacos.core.auth.server.identity.key与nacos.core.auth.server.identity.value默认为空，如果开启了nacos.core.auth.enabled=true 则必须配置这两项，否则启动报错
### Since 1.4.1, worked when nacos.core.auth.enabled=true and nacos.core.auth.enable.userAgentAuthWhite=false.
### The two properties is the white list for auth and used by identity the request from other server.
### 自1.4.1起，在nacos.core.auth.enabled=true和nacos.core.auth.eenable.userAgentAuthWhite=false时起效
### 这两个属性是身份验证的白名单，用于标识来自其他服务器的请求，按需修改配置，如这里都配置为nacos
nacos.core.auth.server.identity.key=nacos
nacos.core.auth.server.identity.value=nacos### ....
### 3. 配置nacos.core.auth.plugin.nacos.token.secret.key，2.2.2起默认为空，必须否则启动时报错
### The default token (Base64 String): 自定义密钥时，推荐将配置项设置为Base64编码的字符串，且原始密钥长度不得低于32字符
nacos.core.auth.plugin.nacos.token.secret.key=VGhpc0lzTXlDdXN0b21TZWNyZXRLZXkwMTIzNDU2Nzg=

开启鉴权配置后，访问时会出现跟2.2.2版本以前一样的的登录界面

2. 鉴权配置不当常见错误

1. 仅开启了鉴权nacos.core.auth.enabled=true ,而未设置nacos.core.auth.server.identity.key与nacos.core.auth.server.identity.value

注意

• Nacos是一个内部微服务组件，需要在可信的内部网络中运行，不可暴露在公网环境，防止带来安全风险。
• Nacos提供简单的鉴权实现，为防止业务错用的弱鉴权体系，不是防止恶意攻击的强鉴权体系。
• 如果运行在不可信的网络环境或者有强鉴权诉求，请参考官方简单实现做进行自定义插件开发。
