• Download the tomcat version of Catalina-jmx-remote.jar from the official website (this uses Tomcat 7.0.81 version)

Tomcat:http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.81/bin/apache-tomcat-7.0.81.tar.gz

Jmx:http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.81/bin/extras/catalina-jmx-remote.jar

Catalina-jmx-remote.jar package is downloaded and placed in Tomcat's Lib directory

[Email protected] lib]# pwd/usr/local/tomcat/lib[[email protected] lib]# wget

• Add the following in bin/catalina.sh (Windows environment Catalina.bat file)

[Email protected] lib]# cd/usr/local/tomcat/bin/[[email protected] bin]# vim catalina.shcatalina_opts= "$CATALINA _ Opts-dcom.sun.management.jmxremote-dcom.sun.management.jmxremote.port=7090-dcom.sun.management.jmxremote.ssl= False-djava.rmi.server.hostname=192.168.100.1-dcom.sun.management.jmxremote.authenticate=true-dcom.sun.manage Ment.jmxremote.password.file=/usr/local/softinstall/tomcat/conf/jmxremote.password- Dcom.sun.management.jmxremote.access.file=/usr/local/softinstall/tomcat/conf/jmxremote.access "

• Edit Access Authorization File

[[email protected] lib]# cd/usr/local/tomcat/conf/[[email protected] conf]# vim Jmxremote.access[[email protected] conf ]# Cat Jmxremote.accessmonitorrole Readonlycontrolrole ReadWrite

• Edit Password file

[Email protected] conf]# vim Jmxremote.password [[email protected] conf]# cat Jmxremote.passwordmonitorrole Tomcatcontrolrole Tomcat

Note: The password file should be read-only and can only be run by Tomcat.

Change Password file permissions, otherwise report the following error:

Error:password file read access must be restricted:/usr/local/tomcat/conf/jmxremote.password

[[email protected] conf]# chmod 0400 jmxremote.password[[email protected] conf]# ll jmxremote.password-r--------1 root R Oot 15:47 Jmxremote.password
