LightDB分布式部署
-
分布式部署模式
# 1.常规模式
1台服务器作为协调者节点，N(N>1)台服务器作为工作节点,每个节点都按照高可用方式进行部署
比如，一个协调节点，2个工作节点，
* 工作节点按照一主一从高可用方式部署，则一共需要[(1+2)*2=6台]服务器
* 工作节点按照一主一从一witness方式部署，则一共需要[(1+2)*3=9台]服务器
# 2.多机单实例
1台服务器作为协调者节点，N(N>1)台服务器作为工作节点,每个节点都按照单机模式部署
# 3.单机多实例
使用1台服务器同时安装协调者节点和工作节点的实例，所有实例均按照单机模式部署
生产环境仅建议使用常规模式部署。-
