阿里云RocketMQ安装

环境安装

1. 先确保已经安装了jdk、maven
2. 下载rocketMQ并且解压安装

// 安装包
https://mirror.bit.edu.cn/apache/rocketmq/4.7.0/rocketmq-all-4.7.0-bin-release.zip
// 源码
wget https://mirror.bit.edu.cn/apache/rocketmq/4.7.0/rocketmq-all-4.7.0-source-release.zip
unzip rocketmq-all-4.7.0-bin-release.zip

配置broker.conf

brokerIP1=XXXXXX

3. 启动Name Server
   守护进程方式启动name server

nohup sh mqnamesrv &

报错：
查看nohup.log日志，出现内存不足的情况。因为官方文件默认启动RocketMQ需要4G内存

// 修改runserver.sh
JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn125m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
// 修改runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn125m"

查看Name Server启动日志

[root@izbp1a2dsv8lw7ik396vokz bin]# tail -f nohup.out 
Java HotSpot(TM) 64-Bit Server VM warning: Using the DefNew young collector with the CMS collector is deprecated and will likely be removed in a future release
Java HotSpot(TM) 64-Bit Server VM warning: UseCMSCompactAtFullCollection is deprecated and will likely be removed in a future release.
The Name Server boot success. serializeType=JSON

4. 启动broker

nohup sh mqbroker -n xx.xx.xxx.xxx:9876 -c ../conf/broker.conf &

5.查看broker 启动日志

[root@izbp1a2dsv8lw7ik396vokz bin]# tail -f nohup.out 
Java HotSpot(TM) 64-Bit Server VM warning: Using the DefNew young collector with the CMS collector is deprecated and will likely be removed in a future release
