1. 下载安装

下载：官网下载

将压缩文件放到 Centos 中
解压：tar -zxvf apache-activemq-5.15.9-bin.tar.gz -C /var
改名：mv /var/apache-activemq-5.15.9/ /var/activemq/

切换目录：cd /var/activemq/

启动：./bin/activemq start

[root@localhost activemq]# ./bin/activemq start
INFO: Loading '/var/activemq//bin/env'
INFO: Using java '/usr/java/jdk1.8.0_211/bin/java'
INFO: Starting - inspect logfiles specified in logging.properties and log4j.properties to get details
INFO: pidfile created : '/var/activemq//data/activemq.pid' (pid '4823')

停止./bin/activemq stop

[root@localhost activemq]# ./bin/activemq stop
INFO: Loading '/var/activemq//bin/env'

2. 创建服务

2.1 创建一个 systemd 服务文件

vi /usr/lib/systemd/system/activemq.service

放入内容

[Unit]
Description=ActiveMQ service
After=network.target

[Service]
Type=forking
ExecStart=/var/activemq/bin/activemq start
ExecStop=/var/activemq/bin/activemq stop
User=root
Group=root
Restart=always
RestartSec=9
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=activemq

[Install]
WantedBy=multi-user.target

加载服务：systemctl daemon-reload

2.2 修改 ActiveMQ 配置

找到 Java 目录：whereis java

[root@localhost activemq]# whereis java
java: /usr/java/jdk1.8.0_211/bin/java

设置 activemq 配置文件 /var/activemq/bin/env 中的 JAVA_HOME

# 注意 JAVA_HOME 前面的 # 要去掉
JAVA_HOME="/usr/java/jdk1.8.0_211"
JAVACMD="auto"

2.3 通过 systemctl 管理 ActiveMQ 启停

启动 activemq 服务: systemctl start activemq
查看服务状态: systemctl status activemq

[root@localhost bin]# systemctl status activemq
● activemq.service - ActiveMQ service
   Loaded: loaded (/usr/lib/systemd/system/activemq.service; enabled; vendor preset: disabled)
   Active: active (running) since Sun 2019-06-23 14:07:25 CST; 1min 59s ago
  Process: 4989 ExecStart=/var/activemq/bin/activemq start (code=exited, status=0/SUCCESS)

Hint: Some lines were ellipsized, use -l to show in full.

创建软链接：ln -s /usr/lib/systemd/system/activemq.service /etc/systemd/system/multi-user.target.wants/activemq.service

开启开机自启：systemctl enable activemq
检测是否开启成功(enable)： systemctl list-unit-files |grep activemq

[root@localhost bin]# systemctl list-unit-files |grep activemq
activemq.service                              enabled 

3. 防火墙配置

Web管理端口默认为8161（admin/admin），通讯端口默认为61616

添加并重启防火墙

firewall-cmd --zone=public --add-port=8161/tcp --permanent
firewall-cmd --zone=public --add-port=61616/tcp --permanent
systemctl restart firewalld.service

或者直接关闭防火墙: systemctl stop firewalld.service

4. web管理系统配置

4.1 端口和登陆

配置文件：/home/activemq/apache-activemq-5.15.9/conf/jetty.xml
端口修改

<bean id="jettyPort" class="org.apache.activemq.web.WebConsolePort" init-method="start">
  <!-- the default port number for the web console -->
  <property name="host" value="0.0.0.0"/>
  <!--此处即为管理平台的端口-->
  <property name="port" value="8161"/>
</bean>

关闭登陆

<bean id="securityConstraint" class="org.eclipse.jetty.util.security.Constraint">
  <property name="name" value="BASIC" />
  <property name="roles" value="user,admin" />
  <!-- 改为false即可关闭登陆 -->
  <property name="authenticate" value="true" />
</bean>

4.2 登陆账号

配置文件：/home/activemq/apache-activemq-5.15.9/conf/jetty-realm.properties
账号修改

# 在此即可维护账号密码，格式：
# 用户名:密码,角色
# Defines users that can access the web (console, demo, etc.)
# username: password [,rolename ...]
admin: admin, admin
user: 123, user
