Linux下rocketmq异步主从搭建

主节点 192.168.0.1 从节点 192.168.0.2

1. 创建目录

mkdir -p /data/rocketmq
cd /data/rocketmq

1.1master

cd /data/rocketmq
unzip rocketmq-all-4.8.0-bin-release
mv rocketmq-all-4.8.0-bin-release master

1.2slave

cd /data/rocketmq
unzip rocketmq-all-4.8.0-bin-release
mv rocketmq-all-4.8.0-bin-release slave

2.修改运行内存限制

编辑rocketmq文件夹下bin目录下的runserver.sh和runbroker.sh脚本

runserver.sh脚本修改内容:

JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

runbroker.sh脚本修改内容:

JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn128m"
JAVA_OPT="${JAVA_OPT} -XX:MaxDirectMemorySize=512m"

3.修改配置文件

3.1主节点

cd /data/rocketmq/master/conf/2m-2s-async
vim broker-a.properties
#集群名称,主从要一样
brokerClusterName=DefaultCluster
#broker名称,主从要一样,根据BrokerRole来确定谁是主谁是从
brokerName=broker-a
#brokerID 0是主,>0是从
brokerId=0
#删除日志时间为凌晨4点
deleteWhen=04
#文件保留时间48小时
fileReservedTime=48
#主从关系,异步复制
brokerRole=ASYNC_MASTER
#刷盘模式,异步刷盘
flushDiskType=ASYNC_FLUSH

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

namesrvAddr地址,分号分割

namesrvAddr=192.168.0.1:9876;192.168.0.2:9876

当前 broker 监听的 IP

brokerIP1=192.168.0.1

存储 commit log 的路径

storePathCommitLog=/data/rocketmq/master/store/commitlog/

存储 consume queue 的路径

storePathConsumerQueue=/data/rocketmq/master/store/consumequeue/

消息索引存储路径

storePathIndex=/data/rocketmq/master/store/index
checkpoint 文件存储路径
storeCheckpoint=/data/rocketmq/master/store/checkpoint
abort 文件存储路径
abortFile=/data/rocketmq/master/store/abort

存储根路径

storePathRootDir=/data/rocketmq/master/store

commit log 的映射文件大小,默认1G

mappedFileSizeCommitLog=1024 * 1024 * 1024

3.2从节点

cd /data/rocketmq/slave/conf/2m-2s-async/
vim broker-a-s.properties
#集群名称,主从要一样
brokerClusterName=DefaultCluster
#broker名称,主从要一样,根据BrokerRole来确定谁是主谁是从
brokerName=broker-a
#brokerID 0是主,>0是从
brokerId=1
#删除日志时间为凌晨4点
deleteWhen=04
#文件保留时间48小时
fileReservedTime=48
#角色是从节点
brokerRole=SLAVE
#刷盘模式,异步刷盘
flushDiskType=ASYNC_FLUSH

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

namesrvAddr地址,分号分割

namesrvAddr=192.168.0.1:9876;192.168.0.2:9876

当前 broker 监听的 IP

brokerIP1=192.168.0.2

存储 commit log 的路径

storePathCommitLog=/data/rocketmq/slave/store/commitlog/

存储 consume queue 的路径

storePathConsumerQueue=/data/rocketmq/slave/store/consumequeue/

消息索引存储路径

storePathIndex=/data/rocketmq/slave/store/index
checkpoint 文件存储路径
storeCheckpoint=/data/rocketmq/slave/store/checkpoint
abort 文件存储路径
abortFile=/data/rocketmq/slave/store/abort

存储根路径

storePathRootDir=/data/rocketmq/slave/store

commit log 的映射文件大小,默认1G

mappedFileSizeCommitLog=1024 * 1024 * 1024

启动主节点

cd /data/rocketmq/master/bin/
#启动NameServer
nohup sh ./mqnamesrv  >/dev/null 2>&1 &
#启动主Broker
nohup sh  ./mqbroker  -c  ../conf/2m-2s-async/broker-a.properties  >/dev/null  2>&1  &

启动从节点

cd /data/rocketmq/slave/bin/
#启动NameServer
nohup sh ./mqnamesrv  >/dev/null 2>&1 &
#启动主Broker
nohup sh  ./mqbroker  -c  ../conf/2m-2s-async/broker-a-s.properties  >/dev/null  2>&1  &
