Jmeter分布式压测原理
- 总控机器的节点master，其他产生压力的机器叫“肉鸡” server
- master会把压测脚本发送到 server上面
- 执行的时候，server上只需要把jmeter-server打开就可以了，不用启动jmeter
- 结束后，server会把压测数据回传给master,然后master汇总输出报告
- 在master和slaves机器上分别按照相同版本的jdk和jmeter
- 在master机器上
1) 修改配置文件，进入jmeter/bin目录下
vim jmeter.properties
remote_hosts=192.168.0.102:8899,192.168.0.101:8899（slaves机器的ip和端口）
server.rmi.ssl.disable=true（禁用ssl）
如果master即作为master也作为slaves
remote_hosts=192.168.0.102:8899,192.168.0.101:8899,master的ip:8899
server_port=8899
server.rmi.ssl.disable=true（禁用ssl）
2) 启动jmeter服务
./jmeter-server（linux）
jmeter-server.bat（windows）
3) 检查是否启动成功
ps -ef|grep jmeter-server
- 在slaves机器上
1) 修改配置文件，进入jmeter/bin目录下
vim jmeter.properties
remote_hosts=127.0.0.1
server_port=8899
server.rmi.ssl.disable=true（禁用ssl）
2) 启动jmeter服务
./jmeter-server（linux）
jmeter-server.bat（windows）
3) 检查是否启动成功
ps -ef|grep jmeter-server
- 分布式执行
GUI模式 ：运行——》远程启动、远程启动全部
non-GUO模式：命令行增加-r参数
jmeter -n -t /Users/jack/Desktop/remote.jmx -r -l /Users/jack/Desktop/jtl/result.jtl -e -o /Users/jack/Desktop/result
JMeter分布式部署遇到的报错问题
Error in rconfigure() method java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: eu.luminis.jmeter.wssampler.OpenWebSocketSampler (no security manager: RMI class loader disabled)
- 情况1
自己配置上禁用ssl了
- 情况2
控制机器和被控制机器插件、或jmeter版本不一致.
