linux，在tomcat bin目录下，使用 shutdown.sh 关闭时，报错： SEVERE: Could not contact [localhost:8005] (base port [8005] and offset [0]). Tomcat may not be running. Jul 17, 2019 10:02:02 AM org.apache.catalina.startup.Catalina stopServer SEVERE: Error stopping Catalina java.net.ConnectException: Connection refused (Connection refused) at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:589) at java.net.Socket.connect(Socket.java:538) at java.net.Socket.(Socket.java:434) at java.net.Socket.(Socket.java:211) at org.apache.catalina.startup.Catalina.stopServer(Catalina.java:513) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.catalina.startup.Bootstrap.stopServer(Bootstrap.java:390) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:480)

这个问题是Tomcat内存导致的，可以修改下Tomcat内存，切换到bin目录下面,使用

vi catalina.sh

修改catalina.sh文件，在位置cygwin=false前,插入以下内容

JAVA_OPTS="-Xms512m -Xmx1024m -Xss2048K -XX:PermSize=256m -XX:MaxPermSize=512m"

重启Tomcat即可。
