# 安装RocketMQ

准备工作

开通端口

firewall-cmd --zone=public --add-port=9876/tcp --permanent
firewall-cmd --zone=public --add-port=10911/tcp --permanent
firewall-cmd --zone=public --add-port=19876/tcp --permanent
firewall-cmd --reload

创建目录

mkdir -p /home/docker/rocketmq/namesrv/logs
mkdir -p /home/docker/rocketmq/broker1/conf
mkdir -p /home/docker/rocketmq/broker1/logs
mkdir -p /home/docker/rocketmq/broker1/store

创建配置文件

cd /home/docker/rocketmq/broker1/conf
touch broker.conf
vim broker.conf

配置文件

# 所属集群名称,如果节点较多可以配置多个
brokerClusterName = DefaultCluster
#broker名称,master和slave使用相同的名称,表明他们的主从关系
brokerName = broker1
#0表示Master,大于0表示不同的slave
brokerId = 0
#表示几点做消息删除动作,默认是凌晨4点
deleteWhen = 04
#在磁盘上保留消息的时长,单位是小时
fileReservedTime = 48
#有三个值:SYNC_MASTER,ASYNC_MASTER,SLAVE;同步和异步表示Master和Slave之间同步数据的机制;
brokerRole = ASYNC_MASTER
#刷盘策略,取值为:ASYNC_FLUSH,SYNC_FLUSH表示同步刷盘和异步刷盘;SYNC_FLUSH消息写入磁盘后才返回成功状态,ASYNC_FLUSH不需要;
flushDiskType = ASYNC_FLUSH
# 设置broker节点所在服务器的ip地址(**这个非常重要,主从模式下,从节点会根据主节点的brokerIP2来同步数据,如果不配置,主从无法同步,brokerIP1设置为自己外网能访问的ip,服务器双网卡情况下必须配置,比如阿里云这种,主节点需要配置ip1和ip2,从节点只需要配置ip1即可)
# 此ip由使用环境决定 本机使用 127 局域网使用 192 外网使用 外网ip
brokerIP1 = 192.168.1.71
#nameServer地址,分号分割
namesrvAddr = 127.0.0.1:9876
#Broker 对外服务的监听端口,
listenPort = 10911
#是否允许Broker自动创建Topic
autoCreateTopicEnable = true
#是否允许 Broker 自动创建订阅组
autoCreateSubscriptionGroup = true
#linux开启epoll
useEpollNativeSelector = true

分配权限(最重要) 为所有目录包括子目录分配读写权限 没有写权限无法存储 会报错无法启动

chmod -R 777 /docker/rocketmq

chmod -R 777 /home/docker/rocketmq/namesrv/logs
