参考:

1. 启动参数java -server -Xms256M -Xmx256M -Xss256K -XX:MetaspaceSize=256M -XX:MaxMetaspaceSize=256M -Dfile.encoding=UTF-8 -Dsun.jun.encoding=UTF-8 -Djava.security.egd=file:/dev/./urandom -Dio.netty.leakDetectionLevel=advanced -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.rmi.port=1919 -Dcom.sun.management.jmxremote.port=1919 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.access.file=/etc/jmx/jmxremote.access -Dcom.sun.management.jmxremote.password.file=/etc/jmx/jmxremote.password -Djava.rmi.server.hostname=服务器公网ip -jar foo.jar

2. authenticate文件配置

jmxremote.access

guest readonly admin readwrite

jmxremote.password

guest guestpwd admin adminpwd注意: 文件(jmxremote.access, jmxremote.password)内容不能有注释

文件授权chmod 600 jmxremote.access

chmod 600 jmxremote.password

chown root:root jmxremote.access

chown root:root jmxremote.password注意不能随便改, chmod 777都不行 否则启动会报错Error: Password file read access must be restricted: /etc/jmx/jmxremote.password sun.management.AgentConfigurationError at sun.management.jmxremote.ConnectorBootstrap.checkPasswordFile(ConnectorBootstrap.java:577) at sun.management.jmxremote.ConnectorBootstrap.startRemoteConnectorServer(ConnectorBootstrap.java:426) at sun.management.Agent.startAgent(Agent.java:262) at sun.management.Agent.startAgent(Agent.java:452)
