部署RocketMQ双主双从异步复制模式

2m-2s-async。多主多从异步复制2m-2s-sync。多主多从同步复制2m-noslave。多主无从

保证主从分布在不同的节点上

RocketMQ二进制安装包
http://rocketmq.apache.org/dowloading/releases/

拷贝至两台机器，解压下载的安装包

第一台机器修改:

rocketmq-all-4.8.0-bin-release/conf/2m-2s-async目录下的broker-a.properties、broker-b-s.properties

第二台机器修改:

rocketmq-all-4.8.0-bin-release/conf/2m-2s-async目录下的broker-b.properties、broker-a-s.properties

在两台机器上创建/home/rocketmq/data、/home/rocketmq/logs目录

vi ~/.bashrc

添加rocketmq环境变量

export ROCKETMQ_HOME=/home/rocketmq/rocketmq-all-4.8.0-bin-release
export PATH=$PATH:$ROCKETMQ_HOME/bin
source ~/.bashrc

确保安装jdk1.8的环境,并配置PATH与JAVA_HOME
两台机器都执行：
进入bin目录：

nohup sh mqnamesrv > /home/rocketmq/logs/mqnamesrv.log 2>&1 &

进入bin目录
修改runbroker.sh,找到下面两行JVM参数，可以调大或调小内存

JAVA_OPT="${JAVA_OPT} -server -Xms2g -Xmx2g -Xmn1g"
JAVA_OPT="${JAVA_OPT} -XX:MaxDirectMemorySize=2g"

修改runserver.sh,找到下面一行JVM参数，可以调大或调小内存

JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:metaspaceSize=64m -XX:MaxmetaspaceSize=160m"

第一台机器启动broker-a：

nohup sh mqbroker -c /home/rocketmq/rocketmq-all-4.8.0-bin-release/conf/2m-2s-async/broker-a.properties > /home/rocketmq/logs/mqbroker-a.log 2>&1 &

第二台机器启动broker-a-s:

nohup sh mqbroker -c /home/rocketmq/rocketmq-all-4.8.0-bin-release/conf/2m-2s-async/broker-a-s.properties > /home/rocketmq/logs/mqbroker-a-s.log 2>&1 &

第二台机器启动broker-b：

nohup sh mqbroker -c /home/rocketmq/rocketmq-all-4.8.0-bin-release/conf/2m-2s-async/broker-b.properties > /home/rocketmq/logs/mqbroker-b.log 2>&1 &

第一台机器启动broker-b-s：

nohup sh mqbroker -c /home/rocketmq/rocketmq-all-4.8.0-bin-release/conf/2m-2s-async/broker-b-s.properties > /home/rocketmq/logs/mqbroker-b-s.log 2>&1 &

sh mqshutdown namesrv
sh mqshutdown broker
