　　Java环境参考：http://visitor.blog.运维网.com/11247238/1956799
　　Tomcat部署参考：http://visitor.blog.运维网.com/11247238/1956809

　　从官网下载Tomcat对应版本的catalina-jmx-remote.jar（这个使用Tomcat 7.0.81版本）

　　Tomcat下载地址：http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.81/bin/apache-tomcat-7.0.81.tar.gz
　　JMX下载地址：http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.81/bin/extras/catalina-jmx-remote.jar
　　catalina-jmx-remote.jar包下载完成后放到Tomcat的lib目录下
[root@test01 lib]# pwd
/usr/local/tomcat/lib
[root@test01 lib]# wget

　　在bin/catalina.sh添加如下内容（Windows环境catalina.bat文件）

[root@test01 lib]# cd /usr/local/tomcat/bin/
[root@test01 bin]# vim catalina.sh
CATALINA_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.management.jmxremote.password.file=/usr/local/softinstall/tomcat/conf/jmxremote.password
  -Dcom.sun.management.jmxremote.access.file=/usr/local/softinstall/tomcat/conf/jmxremote.access"　　

　　编辑访问授权文件

[root@test01 lib]# cd /usr/local/tomcat/conf/
[root@test01 conf]# vim jmxremote.access
[root@test01 conf]# cat jmxremote.access
monitorRole readonly
controlRole readwrite

　　编辑密码文件

[root@test01 conf]# vim jmxremote.password
[root@test01 conf]# cat jmxremote.password
monitorRole tomcat
controlRole tomcat　　注意：密码文件应该是只读的，只能由Tomcat运行用户。
　　更改密码文件权限，否则汇报如下错误：
　　Error: Password file read access must be restricted: /usr/local/tomcat/conf/jmxremote.password
[root@test01 conf]# chmod 0400 jmxremote.password
[root@test01 conf]# ll jmxremote.password
-r-------- 1 root root 36 Aug 25 15:47 jmxremote.password

　　启动Tomcat

[root@test01 conf]# ../bin/startup.sh
Using CATALINA_BASE: /usr/local/softinstall/tomcat
Using CATALINA_HOME: /usr/local/softinstall/tomcat
Using CATALINA_TMPDIR: /usr/local/softinstall/tomcat/temp
