另类--kafka集群中jmx端口设置

# 监控kafka集群
# 有一个问题，需要在kafka-server-start.sh文件中配置端口，有如下三种办法
# 第一种：复制并修改kafka目录，比如kafka-1,kafka-2,kafka-3,然后再每个目录下修改kafka-server-start.sh文件
# 第二种：在启动脚本start.sh中添加指定端口
# 第三种：多复制几个kafka-server-start.sh文件，然后进行修改，最后在start.sh中修改一下

# 以下三种方法任选其一即可

# 第一种方式办法，相应行修改成如下形式，注意端口号不同
# 使用的是不同目录下的不同kafka-server-start.sh文件
# start.sh文件也需要做相应的修改
# kafka-1/bin/kafka-server-start.sh
