记录一次搭建Nacos集群的问题

Java环境：jdk1.8.0_231

Nacos版本：nacos-server-2.2.0.zip

虽然官方推荐的是3个节点，我们还是使用的是2个节点，首先解压创建nacos_config库，导入nacos/conf目录下的mysql-schema.sql SQL文件，如下表：

配置好数据库，application.properties如下图：

#*************** Config Module Related Configurations ***************#
### If use MySQL as datasource:
spring.datasource.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_config
db.password.0=nacos

再打开配置集群文件cluster.conf.example文件，删除.example扩展名，文件cluster.conf如下图:

#2024-10-09T14:03:58.303
127.0.0.1:8848
127.0.0.2:8848

点击nacos/bin目录下的startup.cmd报librocksdbjni错误如下图：

解决方法：下载vc_redist.x64.exe安装提取码：hfeh

OK重新启动，这次报错数据库连接的问题，如下图：

我们开通一下端口
