 # sydapi4j
 
 加密机 java 接口，基于 jna。
+
+
+
+## 启动 Slave
+在作为负载机的 Slave 机器上进行配置，主要有两种方式：
+
+方法一：配置 jmeter.properties 文件
+编辑 $JMETER_HOME/bin/jmeter.properties 文件，确认或取消注释以下配置：
+```
+server.rmi.ssl.disable=true        # 禁用SSL，简化内网配置
+server.rmi.localport=1099          # 固定RMI端口，方便防火墙放行
+java.rmi.server.hostname=Slave_IP  # 绑定本机网卡IP，避免多网卡问题
+```
+
+配置完成后，在 Slave 的 bin 目录下启动服务：
+
+Windows: 双击 jmeter-server.bat
+Linux/Mac: 运行 ./jmeter-server
+
+./jmeter-server -Djava.rmi.server.hostname=172.1.41.24 -Dserver.rmi.localport=1099
