nGrinder 集群模式配置

        前文已经介绍了nGrinder 集群模式基本框架，本文就要涉及具体配置了！

        假设你们已经对nGrinder 单一模式配置方法有所了解。

• 在nGrinder集群模式下多个Controller端使用同一DB和文件系统.因此首先要作的就是搭建好共享文件系统，确认${NGRINDER_HOME} 文件夹。

          在${NGRINDER_HOME}/system.conf 也要有以下配置

# if you want to enable ngrinder controller clustering. please enable below.
ngrinder.cluster.mode = true
 
# cache cluster uri of all clustered controller servers.
# only the controller and agents in same region will work together.
ngrinder.cluster.uris=xx.xx.xx.xx;xx.xx.xx.xx
 
# cache cluster listener port.
ngrinder.cluster.listener.port=40003

• 第二步就要在每一个Controller端添加本地文件夹${NGRINDER_EX_HOME} 。不像${NGRINDER_HOME}，这个文件夹必须手动建立，文件system-ex.conf 配置以下

# region setting of this controller.
# When running ngrinder as cluster mode, the ${NGRINDER_HOME} should be shared by multiple controllers.
# We expect this to be done by running ${NGRINDER_HOME} on NFS.
# However this option is not to set here. Because each controller in cluster must have system-ex.conf
# which should be stored in ${NGRINDER_EX_HOME} in the local so that each node cluster looks different value. 
# Please locate followings this on the ${NGRINDER_EX_HOME}(by default .ngrinder_ex)/system-ex.conf
ngrinder.cluster.region=Beijing

通过以上配置，咱们只要将全部Controller 从新启动，就能够了！

在集群模式下，Agent的配置也会有所不一样。Agent只有设置IP和区域（与Controller 区域相同）才能链接对应Controller。

全部Agent配置文件" ~/.ngrinder-agent"

agent.console.ip=controller ip
agent.console.port= controller port
agent.region={controller region}

若是是用户要配置本身所属Agent

agent.console.ip=controller ip
agent.console.port= controller port
agent.region={controller region}
