注意：安装前先用rpm -q jprofiler查询linux上是否已安装jprofiler
1.到官网下载linux安装包，如：jprofiler_linux_7_1_1.rpm
2.上传该安装包到linxu服务器上/opt目录下，重命名： mv jprofiler_linux_7_1_1.rpm jprofiler7.rmp
（重命名步骤为可选操作，是为了安装时能生成简单的文件目录 jprofiler7）
3.安装： rpm -ivh jprofiler_linux_7_1_1.rpm
4.安装完毕后，在etc/profile中添加：
#Jprofiler Conf
JPROFILER_HOME=/opt/jprofiler7/bin/linux-x64
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$JPROFILER_HOME
5.以tomcat服务为例，在catalina.sh中添加：
#Jprofiler Conf
JAVA_OPTS="$JAVA_OPTS -agentlib:jprofilerti=port=8849-Xbootclasspath/a:/opt/jprofiler7/bin/agent.jar"
6.在startup.sh中添加：
#Jprofiler Conf
CATALINA_OPTS="-agentpath:/opt/jprofiler7/bin/linux-x64/libjprofilerti.so=port=8849,nowait$CATALINA_OPTS"
export CATALINA_OPTS
1.测试环境
服务器：RedHat Linux 3.4.3-9.EL4（内核版本 2.6.9-5.EL），Tomcat5.5.20，Sun JDK 1.5.0_09，JProfiler 4.3.2 for linux（安装包：jprofiler_linux_4_3_2.sh）
客户端：Windows XP，JProfiler 4.3.2 for windows（安装包：jprofiler_windows_4_3_2.exe）
2.JProfiler软件下载地址 http://www.ej-technologies.com/
3.客户端 JProfiler 安装 略
4.服务器端 JProfiler 安装：
把 jprofiler_linux_4.3.2.sh 上传到到服务器，假设路径为 /opt/jprofiler
# cd /opt/jprofiler
# chmod +x *.sh
# ./jprofiler_linux_4.3.2.sh -c
按照提示来安装，提示都很简单，不在多说。安装路径选择 /opt/jprofiler4
注意，这里的 -c 意思是用字符方式来安装，如果机器上没有 X 则加上该参数.
5.客户端连接配置
1). 运行 JProfiler 。第一次打开会有向导，忽略它。
2). 选择 Session->Integration Wizard->New Remote Integratation
3). 选择 On a remote computer；Platform of remote computer 选择 Linux x86/AMD 64；Next
4). 输入服务器 IP ；Next
5). 输入服务器上的 jprofiler 的安装路径，如 /opt/jprofiler4 ；next
6). 选择服务器的 JDK 环境，这里是：Sun，1.5.0，hotspot；next
7). 输入端口：这里是默认值 8849；next
8). 选择启动模式：这里选第一种 wait for a connection from the jprofiler GUI；next
9). 这里会列出需要在服务器端做的配置:
Integration type: [Generic application]
Selected JVM: Sun 1.5.0 (hotspot)
Startup mode: Wait for JProfiler GUI
(1) Please insert
-agentlib:jprofilerti=port=8849 -Xbootclasspath/a:/opt/jprofiler4/bin/agent.jar
into the start command of your remote application right after the java command.
(2) Please add
/opt/jprofiler4/bin/linux-x86
to the environment variable LD_LIBRARY_PATH.
A remote session named Remote application on 192.168.40.15 will be created that connects to a running instance of the remote application that is started with the modified start command.
6.服务器端的配置
(1)修改系统环境配置文件 /etc/profile ,增加
JPROFILER_HOME=/opt/jprofiler4/bin/linux-x86
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$JPROFILER_HOME
(2)修改TOMCAT启动文件catalina.sh，添加-agentlib:jprofilerti=port=8849 -Xbootclasspath/a:/opt/jprofiler4/bin/agent.jar 内容到CATALINA_OPTS中；
“-agentlib:jprofilerti=port=8849 -Xbootclasspath/a:/opt/jprofiler4/bin/agent.jar ” 此内容由客户端软件生成
CATALINA_OPTS="$CATALINA_OPTS -Xms128m -Xmx128m $JPDA_OPTS -agentlib:jprofilerti=port=8849 -Xbootclasspath/a:/opt/jprofiler4/bin/agent.jar"
7.Reboot Linux and startup Tomcat using startup.sh;
The log of tomcat which is $CATALINA_HOME/logs/catalina.out will show:
JProfiler> Protocol version 23
JProfiler> Using JVMTI
JProfiler> 32-bit library
JProfiler> Listening on port: 8849.
JProfiler> Native library initialized
JProfiler> Waiting for a connection from the JProfiler GUI 
8.启动客户端软件
点击jprofiler菜单 session>start center>Open Session
Available session configurations中列出了刚才配置的连接，选中使用就OK了！！
9.The log of tomcat which is $CATALINA_HOME/logs/catalina.out will show:
JProfiler> Using dynamic instrumentation
JProfiler> Time measurement: elapsed time
JProfiler> CPU profiling enabled
JProfiler> Hotspot compiler enabled
JProfiler> Starting org/apache/catalina/startup/Bootstrap
10.当中断JProfiler连接时
The log of tomcat which is $CATALINA_HOME/logs/catalina.out will show:
JProfiler> Disconnected. Waiting for reconnection.
JProfiler> Listening on port: 8849.
