20200202 ActiveMQ 2. ActiveMQ安装和控制台

Linux 安装 ActiveMQ

安装步骤：

1. 下载安装包（Linux格式）

官网下载

2. 解压到/opt目录

tar -zxvf apache-activemq-5.15.11-bin.tar.gz

3. 根目录下新建文件夹myactivemq

mkdir /myactivemq

4. 将解压后的activemq目录拷贝到myactivemq

cp -r /opt/apache-activemq-5.15.11 /myactivemq/

5. 普通启动与带运行日志启动
   启动命令在bin目录下

# 普通启动
[root@hwjsLinux bin]# ./activemq start
INFO: Loading '/myactivemq/apache-activemq-5.15.11//bin/env'
INFO: Using java '/usr/bin/java'
INFO: Starting - inspect logfiles specified in logging.properties and log4j.properties to get details
INFO: pidfile created : '/myactivemq/apache-activemq-5.15.11//data/activemq.pid' (pid '2720')

在最后一行可以看到pid为2720

# 带运行日志启动
./activemq start > /myactivemq/run.log

6. 验证启动成功

activemq默认启动端口是61616

# 查询activemq的进程状态
[root@hwjsLinux bin]# ps -ef | grep activemq
root       2720      1 12 17:38 pts/0    00:00:06 /usr/bin/java -Xms64M -Xmx1G -Djava.util.logging.config.file=logging.properties -Djava.security.auth.login.config=/myactivemq/apache-activemq-5.15.11//conf/login.config -Dcom.sun.management.jmxremote -Djava.awt.headless=true -Djava.io.tmpdir=/myactivemq/apache-activemq-5.15.11//tmp -Dactivemq.classpath=/myactivemq/apache-activemq-5.15.11//conf:/myactivemq/apache-activemq-5.15.11//../lib/: -Dactivemq.home=/myactivemq/apache-activemq-5.15.11/ -Dactivemq.base=/myactivemq/apache-activemq-5.15.11/ -Dactivemq.conf=/myactivemq/apache-activemq-5.15.11//conf -Dactivemq.data=/myactivemq/apache-activemq-5.15.11//data -jar /myactivemq/apache-activemq-5.15.11//bin/activemq.jar start
root       2779   2574  0 17:39 pts/0    00:00:00 grep --color=auto activemq


## 排除grep命令产生的进程状态
[root@hwjsLinux bin]# ps -ef | grep activemq | grep -v grep
root       2720      1  8 17:38 pts/0    00:00:06 /usr/bin/java -Xms64M -Xmx1G -Djava.util.logging.config.file=logging.properties -Djava.security.auth.login.config=/myactivemq/apache-activemq-5.15.11//conf/login.config -Dcom.sun.management.jmxremote -Djava.awt.headless=true -Djava.io.tmpdir=/myactivemq/apache-activemq-5.15.11//tmp -Dactivemq.classpath=/myactivemq/apache-activemq-5.15.11//conf:/myactivemq/apache-activemq-5.15.11//../lib/: -Dactivemq.home=/myactivemq/apache-activemq-5.15.11/ -Dactivemq.base=/myactivemq/apache-activemq-5.15.11/ -Dactivemq.conf=/myactivemq/apache-activemq-5.15.11//conf -Dactivemq.data=/myactivemq/apache-activemq-5.15.11//data -jar /myactivemq/apache-activemq-5.15.11//bin/activemq.jar start

通过端口号查询可以查到pid：

# 通过端口号查询，使用netstat命令
[root@hwjsLinux bin]# netstat -anp | grep 61616
tcp6       0      0 :::61616                :::*                    LISTEN      2720/java           

[root@hwjsLinux bin]# lsof -i:61616
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
java    2720 root  130u  IPv6  37552      0t0  TCP *:61616 (LISTEN)

7. 关闭与重启命令

# 关闭
./activemq stop

# 重启
./activemq restart

ActiveMQ 控制台

这里是以Windows内的VMWare内的Linux启动ActiveMQ服务，然后使用Windows浏览器访问ActiveMQ 控制台。

1. 获取Linux的IP地址

这里VMWare使用的是NAT模式，由ifconfig命令结果可知，ip地址为192.168.181.128

[root@hwjsLinux bin]# ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.181.128  netmask 255.255.255.0  broadcast 192.168.181.255
        inet6 fe80::4797:731b:a68d:fbac  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:1a:9c:db  txqueuelen 1000  (Ethernet)

        TX packets 3449  bytes 415807 (406.0 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>

        TX packets 174  bytes 66971 (65.4 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

virbr0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 192.168.122.1  netmask 255.255.255.0  broadcast 192.168.122.255
        ether 52:54:00:fa:ab:93  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

2. Windows浏览器访问ActiveMQ服务

• 61616 是后台进程的端口号，用来提供JMS服务
• 8161 是前台web访问的端口号，用来提供管理控制台服务

根据1.中的IP地址，得出访问地址为：

http://192.168.181.128:8161/

默认用户名/密码为admin/admin

解决无法访问的问题

1. Windows无法ping通Linux的IP地址
   需要启动服务中的VMware DHCP Service和VMware NAT Service
2. 可以ping通，Linux内可以访问到ActiveMQ服务，Windows浏览器访问不到
   需要配置Linux防火墙，这里因为是测试，所以直接关闭防火墙

systemctl stop firewalld.service
