wrapper | JVM exited while loading the application.
jvm 1 | Invalid maximum heap size: -Xmx4G

jvm 1 | Error: Could not create the Java Virtual Machine.
jvm 1 | Error: A fatal exception has occurred. Program will exit.

解决办法：

#最大内存不足Xmx4G，设置相关启动的配置文件
vi /usr/local/mycat/conf/wrapper.conf

wrapper.java.additional.10=-Xmx4G
wrapper.java.additional.11=-Xms1G
改为：
wrapper.java.additional.10=-Xmx512M
wrapper.java.additional.11=-Xms64M

再次启动，正常：
#启动 mycat ，正常
