Jconsole 测试.

1 下载并安装

d:\Program Files\Java\jdk1.8.0_111\

JDK自带，Windows下图形界面，监控分析Java程序

2 查看jmx进程号

[root@hongquan ~]# ps -eaf|grep jmx

org.tanukisoftware.wrapper.WrapperSimpleApp io.mycat.MycatStartup start

root 41638 37788 0 01:18 pts/8 00:00:00 grep jmx

查看进程号34501的tcp端口号

[root@hongquan ~]# netstat -ntpl|grep 34501

tcp 0 0 127.0.0.1:32000 0.0.0.0:* LISTEN 34501/java

tcp 0 0 :::45438 :::* LISTEN 34501/java

tcp 0 0 :::1984 :::* LISTEN 34501/java

tcp 0 0 :::8066 :::* LISTEN 34501/java

tcp 0 0 :::54856 :::* LISTEN 34501/java

tcp 0 0 :::9066 :::* LISTEN 34501/java

3 添加新帐号jconsole用来连接

[root@hongquan ~]# useradd jconsole

[root@hongquan ~]# gpasswd -ajconsole root

Adding user jconsole to group root

[root@hongquan ~]# passwd jconsole

Changing password for user jconsole.

New password:

BAD PASSWORD: it is based on a dictionary word

Retype new password:

passwd: all authentication tokens updated successfully.

4 连接root@10.0.1.134:1984

D:\program files\Java\jdk1.8.0_111\bin

双击jconsole.exe打开

[root@hongquan conf]# more wrapper.conf |grep 1984

wrapper.java.additional.7=-Dcom.sun.management.jmxremote.port=1984

[root@hongquan conf]# vim wrapper.conf

[root@hongquan conf]# more wrapper.conf |grep 1984

wrapper.java.additional.7=-Dcom.sun.management.jmxremote.port=51984

修改51984

用Jconsole连接报错，将mycat的wrapper.conf配置更改如下：

重启mycat

[root@hongquan bin]# ./mycat restart

Stopping Mycat-server...

Stopped Mycat-server.

Starting Mycat-server...
