CentOS7 本地部署RocketMQ

lcc0556
描述项 内容
操作系统 CentOS Linux release 7.9.2009 (Core)
JDK jdk-21.0.3
RocketMQ rocketmq-all-5.2.0

file

1. 环境准备

安装JDK：http://dba.qishuo.xin/?p=3964

2. 下载RocketMQ

下载二进制包

cd /media
wget https://dist.apache.org/repos/dist/release/rocketmq/5.2.0/rocketmq-all-5.2.0-bin-release.zip

file

3. 解压文件

cd /media
unzip -n rocketmq-all-5.2.0-bin-release.zip -d /usr/local/
mv /usr/local/rocketmq-all-5.2.0-bin-release /usr/local/rocketmq
# 为了解决broker.log日志一直打印/usr/local/rocketmq/conf/acl is not exist,在这里手动创建一个空目录
mkdir -p /usr/local/rocketmq/conf/acl

file

4. 参数配置

4.1. 内存及JAVA_HOME配置

JAVA_HOME 配置为：/usr/local/java/jdk-21.0.3
内存配置为：-server -Xms256m -Xmx256m -Xmn256m -XX:PermSize=128m-XX:MaxPermSize=128m

(1)在目录/usr/local/rocketmq/bin下找到文件：runserver.sh、runbroker.sh、tools.sh

file

(2)修改配置runserver.sh：runserver.sh
file

(3)修改配置runbroker.sh：vim runbroker.sh
file

(4)修改配置tools.sh：tools.sh
file

4.2. 修改日志保存目录

启动NameServer、Broker服务后，默认的日志会保存在启动服务的用户根目录中。要修改日志的位置，仍然是对runnamesrv.sh和runserver.sh两个文件做修改，在末尾处添加如下内容：

#rewrite user home
JAVA_OPT="${JAVA_OPT} -Duser.home=新目录(如:/usr/local/rocketmq)"

5. 编辑启动脚本

5.1. 创建NameServer服务文件

进入/lib/systemd/system目录下，创建rocketmq-namesrv.service文件(touch rocketmq-namesrv.service)，内容如下：

[Unit]
Description=RocketMQ Namesrv
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=sample
User=root
ExecStart=/usr/local/rocketmq/bin/mqnamesrv
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
Restart=0
LimitNOFILE=65536

[Install]
WantedBy=multi-user.target

5.2. 创建broker服务文件

进入/lib/systemd/system目录下，创建rocketmq-broker.service文件(touch rocketmq-broker.service)，内容如下：

[Unit]
Description=rocketmq-broker
After=network.target

[Service]
Type=sample
User=root
ExecStart=/usr/local/rocketmq/bin/mqbroker -n localhost:9876 --enable-proxy
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
Restart=0
LimitNOFILE=65536

[Install]
WantedBy=multi-user.target

6. 启动NameServer与Broker

6.1. 重新加载systemd守护进程的配置文件

systemctl daemon-reload

6.2. 停止与启动NameServer

systemctl stop rocketmq-namesrv.service
systemctl start rocketmq-namesrv.service
systemctl status rocketmq-namesrv.service

file

6.3. 停止与启动Broker

systemctl stop rocketmq-broker.service
systemctl start rocketmq-broker.service
systemctl status rocketmq-broker.service

file

6.4. 设置开机自启动

systemctl enable rocketmq-broker.service
systemctl enable rocketmq-namesrv.service

6.5. 防火墙端口开放

rocketmq 常用默认端口：9876、10911、10909

  • 9876：NameServer通信端口。客户端通过该端口与NameServer通信。

  • 10911：remotingServer使用的监听端口，主要用途：

    1. producer发送的消息
    2. conumser在消费失败或者消费超时发送的消息
    3. consumer拉取消息
    4. 10912是主broker用于监听从broker请求的监听端口。

使用中遇到的场景：10911端口未开发，消费者订阅进行消费时，无消息可消费，查看客户端日志发现getConsumerIdListByGroup exception失败。

  • 10909：fastRemotingServer使用的监听端口，与remotingServer类似，vipChannelEnabled开启时，消息发送到fastRemotingServer。也可称为vip通道端口。
firewall-cmd --zone=public --add-port=9876/tcp --permanent
firewall-cmd --zone=public --add-port=10909/tcp --permanent
firewall-cmd --zone=public --add-port=10911/tcp --permanent
firewall-cmd --reload

7. 测试RocketMQ

7.1. 发送消息

# 1.设置环境变量
export NAMESRV_ADDR=localhost:9876
# 2.使用安装包的Demo发送消息
cd /usr/local/rocketmq
sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer

7.2. 接受消息

# 1.设置环境变量
export NAMESRV_ADDR=localhost:9876
# 2.接收消息
cd /usr/local/rocketmq
sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer

8. RocketMQ的Web管理控制台(Dashboard)

8.1. 下载源码并打成jar包

gitHub地址：https://github.com/apache/rocketmq-dashboard

cd rocketmq-dashboard
mvn clean package -Dmaven.test.skip=true
java -jar target/rocketmq-dashboard-1.0.1-SNAPSHOT.jar

8.2. 启动jar包

 nohup java -jar /usr/local/rocketmq/rocketmq-dashboard-1.0.1-SNAPSHOT.jar --server.port=8082 --rocketma.config.namesrvAddr=172.16.5.74:9876 > /usr/local/rocketmq/logs/dashboard.log 2>&1 &

8.3. 登录Web
