扩容集群 #

使用命令 spex cluster scale --name <cluster-name> --host <host-ip> 扩容集群。

示例: 在 demo 集群扩容 IP 为 10.0.1.2 的 ShardingSphere-Proxy 节点。

$ spex cluster scale --name demo --host 10.0.1.2

2.执行命令 spex cluster install -n demo --type proxy --host 10.0.1.2 安装新增节点 。

[root@community /]# spex cluster install -n demo --type proxy --host 10.0.1.2
ShardingSphere-Proxy
check proxy install dir exist!      
Completed.......

3.执行命令 spex cluster start --name demo --type proxy --host 10.0.1.2 启动新增节点。

[root@community /]# spex cluster start --name demo --type proxy --host 10.0.1.2
ShardingSphere-Proxy
start proxy      
10.0.1.2:3388 =>success
