- 高可用 Nginx 集群
- Nacos 集群(至少三个实例)
- 高可用数据库集群(取代 Nacos 内嵌数据库)
集群使用版本:
Nginx 1.24.0
Nacos 2.2.3
服务器 | IP | 服务器版本 |
---|---|---|
Nginx | 18.18.18.40 | CentOS-7.9 |
MySQL | 18.18.18.88 | CentOS-7.9 |
Nacos1 | 18.18.18.41 | CentOS-7.9 |
Nacos2 | 18.18.18.42 | CentOS-7.9 |
Nacos3 | 18.18.18.43 | CentOS-7.9 |
