RocketMQ 异步复制集群部署安装

1.RacketMQ多种部署模式

RocketMQ Broker集群部署方式主要有以下几种：（Slave 不可写，但可读）
1.1.单个Master
这种方式风险较大，一旦Broker 重启或者宕机时，会导致整个服务不可用，不建议线上环境使用。
1.2.多Master模式
一个集群无 Slave，全是 Master，例如 2 个 Master 或者 3 个 Master。

优点：配置简单，单个Master 宕机或重启维护对应用无影响，在磁盘配置为 RAID10 时，即使机器宕机不可恢复情况下，由与 RAID10 磁盘非常可靠，消息也不会丢（异步刷盘丢失少量消息，同步刷盘一条不丢）。性能最高。

缺点：单台机器宕机期间，这台机器上未被消费的消息在机器恢复之前不可订阅，消息实时性会受到受到影响。

优点：即使磁盘损坏，消息丢失的非常少，且消息实时性不会受影响，因为 Master 宕机后，消费者仍然可以从 Slave 消费，此过程对应用透明。不需要人工干预。性能同多 Master 模式几乎一样。

缺点：Master 宕机，磁盘损坏情况，会丢失少量消息。

# 先启动 NameServer，例如机器 IP 为：”10.162.23.70:9876;10.162.23.71:9876”
# nohup ./bin/mqnamesrv >/dev/null 2>&1 &
# 在机器 A，启动第一个 Master
# nohup ./bin/mqbroker -n “10.162.23.70:9876;10.162.23.71:9876” -c ./conf/2m-2s-async/broker-a.properties >/dev/null 2>&1 &
# 在机器 B，启动第二个 Master
# nohup ./bin/mqbroker -n “10.162.23.70:9876;10.162.23.71:9876” -c ./conf/2m-2s-async/broker-b.properties >/dev/null 2>&1 &
#在机器 C，启动第一个 Slave
nohup ./bin/mqbroker -n “10.162.23.70:9876;10.162.23.71:9876” -c ./conf/2m-2s-async/broker-a-s.properties >/dev/null 2>&1 &
# 在机器 D，启动第二个 Slave
# nohup ./bin/mqbroker -n “10.162.23.70:9876;10.162.23.71:9876” -c ./conf/2m-2s-async/broker-b-s.properties >/dev/null 2>&1 &
1.4.多Master多Slave模式，同步双写
每个 Master 配置一个 Slave，有多对Master-Slave，HA 采用同步双写方式，主备都写成功，向应用返回成功。

优点：数据与服务都无单点，Master宕机情况下，消息无延迟，服务可用性与数据可用性都非常高

缺点：性能比异步复制模式略低，大约低 10%左右，发送单个消息的 RT 会略高。目前主宕机后，备机不能自动切换为主机，后续会支持自动切换功能。

# 先启动 NameServer，例如机器 IP 为：”10.162.23.70:9876;10.162.23.71:9876”
# nohup ./bin/mqnamesrv >/dev/null 2>&1 &
# 在机器 A，启动第一个 Master
# nohup ./bin/mqbroker -n “10.162.23.70:9876;10.162.23.71:9876” -c ./conf/2m-2s-sync/broker-a.properties >/dev/null 2>&1 &
# 在机器 B，启动第二个 Master
# nohup ./bin/mqbroker -n “10.162.23.70:9876;10.162.23.71:9876” -c ./conf/2m-2s-sync/broker-b.properties >/dev/null 2>&1 &
# 在机器 C，启动第一个 Slave
# nohup ./bin/mqbroker -n “10.162.23.70:9876;10.162.23.71:9876” -c ./conf/2m-2s-sync/broker-a-s.properties >/dev/null 2>&1 &
# 在机器 D，启动第二个 Slave
# nohup ./bin/mqbroker -n “10.162.23.70:9876;10.162.23.71:9876” -c ./conf/2m-2s-sync/broker-b-s.properties >/dev/null 2>&1 &

注：
以上 Broker 与 Slave 配对是通过指定相同的brokerName 参数来配对，Master 的 BrokerId 必须是 0，Slave 的BrokerId 必须是大与 0 的数。另外一个 Master 下面可以挂载多个 Slave，同一 Master 下的多个 Slave 通过指定不同的 BrokerId 来区分。
除此之外，nameserver也需要集群。我们的环境采用多nameserver多master多slave异步复制模式
