启动时可能遇到java mysql的时区问题
unrecognized or represents more than one time zone. You must configure either the server or JDBC driver
解决方案：需要在Url后面添加一个参数：?serverTimezone=UTC
jdbc_connection_string => "jdbc:mysql://127.0.0.1:3306/data?serverTimezone=UTC"
运行出现you must change the "path.data" setting.
修改启动命令： /bin/logstash -f xxxxx.conf
为： /bin/logstash -f xxxxxx.conf --path.data=/root/
