jconsole监控linux系统的jvm使用

1.在linux系统下载安装jdk和tomcat

2.配置tomcat参数

[[email protected] ~]# vim /usr/local/tomcat-7.0.64Front/bin/catalina.sh

JAVA_OPTS="$JAVA_OPTS

-Dcom.sun.management.jmxremote     --远程登陆

-Dcom.sun.management.jmxremote.port=9004   -开放端口

-Dcom.sun.management.jmxremote.authenticate=true   --用户密码认证

-Dcom.sun.management.jmxremote.ssl=false        --不启用ssl

-Dcom.sun.management.jmxremote.access.file=/usr/local/jdk1.7.0_80/jre/lib/management/

jmxremote.access      --访问权限

-Dcom.sun.management.jmxremote.password.file=/usr/local/jdk1.7.0_80/jre/lib/management/

jmxremote.password    --访问密码

"

[[email protected] ~]# cd /usr/local/jdk1.7.0_80/jre/lib/management/

[[email protected] management]# cp -a jmxremote.password.template  jmxremote.password

[[email protected] management]# vim jmxremote.password

tingyun  system   --用户名和密码

[[email protected] management]# vim jmxremote.access

#monitorRole   readonly    --注释

#              unregister

tingyun readwrite   --用户授权(readonly  只读   readwrite  读写)

[[email protected] management]# chmod  600 jmxremote.password jmxremote.access

[[email protected] management]# /usr/local/tomcat-7.0.64Front/bin/shutdown.sh

[[email protected] management]# /usr/local/tomcat-7.0.64Front/bin/startup.sh

[[email protected] management]# netstat -antulp | grep 9004
