+## 运维管理(operation)
+
+### 1   集群搭建
+
+#### 1.1 单Master模式
+
+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,可以用于本地测试。
+
+##### 1)启动 NameServer
+
+```bash
+### 首先启动Name Server,例如机器IP为:192.161.1:9876
+$ nohup sh mqnamesrv &
+ 
+### 验证Name Server 是否启动成功
+$ tail -f ~/logs/rocketmqlogs/namesrv.log
+The Name Server boot success...
+```
+
+##### 2)启动 Broker
+
+```bash
+### 启动Broker,例如机器IP为:192.161.1:9876
+$ nohup sh bin/mqbroker -n localhost:9876 &
+### 验证Name Server 是否启动成功
+$ tail -f ~/logs/rocketmqlogs/Broker.log 
+The broker[%s, 172.30.30.233:10911] boot success...
+```
+
+#### 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,这种模式的优缺点如下:
+
+- 
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,由于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。
+
+##### 1)启动NameServer
+
+NameServer需要先于Broker启动,生产环境 
需要启动多个保证高可用,一般规模的集群启动3个NameServer即可,各节点的启动命令相同,命令如下:
+
+```bash
+### 首先启动Name Server,例如机器IP为:192.161.1:9876
+$ nohup sh mqnamesrv &
+ 
+### 验证Name Server 是否启动成功
+$ tail -f ~/logs/rocketmqlogs/namesrv.log
+The Name Server boot success...
+```
+
+##### 2)启动Broker集群
+
+```bash
+### 在机器A,启动第一个Master
+$ nohup sh mqbroker -n 192.161.1:9876 -c 
$ROCKETMQ_HOME/conf/2m-noslave/broker-a.properties &
+ 
+### 在机器B,启动第二个Master
+$ nohup sh mqbroker -n 192.161.1:9876 -c 
$ROCKETMQ_HOME/conf/2m-noslave/broker-b.properties &
+
+...
+```
+
+如上启动命令是在单个NameServer情况下使用的。对于多个NameServer的集群,Broker启动命令中 -n后面的地址列表用分号隔开即可,例如 
192.161.1:9876;192.161.2:9876。
+
+#### 1.3 多Master多Slave模式-异步复制
+
+每个Master配置一个Slave,有多对Master-Slave,HA采用异步复制方式,主备有短暂消息延迟,毫秒级,这种模式的优缺点如下:
+
+- 
优点:即使磁盘损坏,消息丢失的非常少,且消息实时性不会受影响,因为Master宕机后,消费者仍然可以从Slave消费,此过程对应用透明。不需要人工干预。性能同多Master模式几乎一样;
+
+- 缺点:Master宕机,磁盘损坏情况,会丢失少量消息。
+
+##### 1)启动NameServer
+
+```bash
+### 首先启动Name Server,例如机器IP为:192.161.1:9876
+$ nohup sh mqnamesrv &
+ 
+### 验证Name Server 是否启动成功
+$ tail -f ~/logs/rocketmqlogs/namesrv.log
+The Name Server boot success...
+```
+
+##### 2)启动Broker集群
+
+```bash
+### 在机器A,启动第一个Master
+$ nohup sh mqbroker -n 192.161.1:9876 -c 
$ROCKETMQ_HOME/conf/2m-2s-async/broker-a.properties &
+ 
+### 在机器B,启动第二个Master
+$ nohup sh mqbroker -n 192.161.1:9876 -c 
$ROCKETMQ_HOME/conf/2m-2s-async/broker-b.properties &
+ 
+### 在机器C,启动第一个Slave
+$ nohup sh mqbroker -n 192.161.1:9876 -c 
$ROCKETMQ_HOME/conf/2m-2s-async/broker-a-s.properties &
+ 
+### 在机器D,启动第二个Slave
+$ nohup sh mqbroker -n 192.161.1:9876 -c 
$ROCKETMQ_HOME/conf/2m-2s-async/broker-b-s.properties &
+```
+
+#### 1.4 多Master多Slave模式-同步双写
+
+每个Master配置一个Slave,有多对Master-Slave,HA采用同步双写方式,主备都写成功,向应用返回成功,这种模式的优缺点如下:
+
+- 优点:数据与服务都无单点,Master宕机情况下,消息无延迟,服务可用性与数据可用性都非常高;
+
+- 缺点:性能比异步复制模式略低,大约低10%左右,发送单个消息的RT会略高。目前主宕机后,备机不能自动切换为主机,后续会支持自动切换功能。
+
+##### 1)启动NameServer
+
+```bash
+### 首先启动Name Server,例如机器IP为:192.161.1:9876
+$ nohup sh mqnamesrv &
+ 
+### 验证Name Server 是否启动成功
+$ tail -f ~/logs/rocketmqlogs/namesrv.log
+The Name Server boot success...
+```
+
+##### 2)启动Broker集群
+
+```bash
+### 在机器A,启动第一个Master
+$ nohup sh mqbroker -n 192.161.1:9876 -c 
$ROCKETMQ_HOME/conf/2m-2s-sync/broker-a.properties &
+ 
+### 在机器B,启动第二个Master
+$ nohup sh mqbroker -n 192.161.1:9876 -c 
$ROCKETMQ_HOME/conf/2m-2s-sync/broker-b.properties &
+ 
+### 在机器C,启动第一个Slave
+$ nohup sh mqbroker -n 192.161.1:9876 -c 
$ROCKETMQ_HOME/conf/2m-2s-sync/broker-a-s.properties &
+ 
+### 在机器D,启动第二个Slave
+$ nohup sh mqbroker -n 192.161.1:9876 -c 
$ROCKETMQ_HOME/conf/2m-2s-sync/broker-b-s.properties &
+```
+
+以上Broker与Slave配对是通过指定相同的BrokerName参数来配对,Master的BrokerId必须是0,Slave的BrokerId必须是大于0的数。另外一个Master下面可以挂载多个Slave,同一Master下的多个Slave通过指定不同的BrokerId来区分。$ROCKETMQ_HOME指的RocketMQ安装目录,需要用户自己设置此环境变量。
+
+### 2 mqadmin管理工具
+
+> 注意:
+>
+> 1. 执行命令方法:`./mqadmin {command} {args}`
+> 2. 几乎所有命令都需要配置-n表示namesrv地址,格式为ip:port
+> 3. 几乎所有命令都可以通过-h获取帮助
+> 4. 
如果既有Broker地址(-b)配置项又有clusterName(-c)配置项,则优先以Broker地址执行命令,如果不配置Broker地址,则对集群中所有主机执行命令,只支持一个Broker地址。-b格式为ip:port,port默认是10911
+> 5. 
在tools下可以看到很多命令,但并不是所有命令都能使用,只有在MQAdminStartup中初始化的命令才能使用,你也可以修改这个类,增加或自定义命令
+> 6. 由于版本更新问题,少部分命令可能未及时更新,遇到错误请直接阅读相关命令源码

+### 3   运维常见问题
+
+#### 3.1 RocketMQ的mqadmin命令报错问题
+
+>  问题描述:有时候在部署完RocketMQ集群后,尝试执行“mqadmin”一些运维命令,会出现下面的异常信息:
+>
+> ```java
+> org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to 
<null> failed
+> ```
+
+解决方法:可以在部署RocketMQ集群的虚拟机上执行`export 
NAMESRV_ADDR=ip:9876`(ip指的是集群中部署NameServer组件的机器ip地址)命令之后再使用“mqadmin”的相关命令进行查询,即可得到结果。
+
+#### 3.2 RocketMQ生产端和消费端版本不一致导致不能正常消费的问题
+
+> 问题描述:同一个生产端发出消息,A消费端可消费,B消费端却无法消费,rocketMQ Console中出现:
+>
+> ```java
+> Not found the consumer group consume stats, because return offset table is 
empty, maybe the consumer not consume any message的异常消息。
+> ```
+
+  解决方案:RocketMQ 的jar包:rocketmq-client等包应该保持生产端,消费端使用相同的version。
+
+#### 3.3  新增一个topic的消费组时,无法消费历史消息的问题
+
+> 问题描述:当同一个topic的新增消费组启动时,消费的消息是当前的offset的消息,并未获取历史消息。    
+
+解决方案:rocketmq默认策略是从消息队列尾部,即跳过历史消息。如果想消费历史消息,则需要设置:`org.apache.rocketmq.client.consumer.DefaultMQPushConsumer#setConsumeFromWhere`。常用的有以下三种配置:
+
+- 默认配置,一个新的订阅组第一次启动从队列的最后位置开始消费,后续再启动接着上次消费的进度开始消费,即跳过历史消息;
+
+```java
+consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_LAST_OFFSET);
+```
+
+- 一个新的订阅组第一次启动从队列的最前位置开始消费,后续再启动接着上次消费的进度开始消费,即消费Broker未过期的历史消息;
+
+```java
+consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);
+```
+
+- 
一个新的订阅组第一次启动从指定时间点开始消费,后续再启动接着上次消费的进度开始消费,和consumer.setConsumeTimestamp()配合使用,默认是半个小时以前;
+
+```java
+consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_TIMESTAMP);
+```
+
+#### 3.4 如何开启从Slave读数据功能
+
+在某些情况下,Consumer需要将消费位点重置到1-2天前,这时在内存有限的Master 
Broker上,CommitLog会承载比较重的IO压力,影响到该Broker的其它消息的读与写。可以开启`slaveReadEnable=true`,当Master
 
Broker发现Consumer的消费位点与CommitLog的最新值的差值的容量超过该机器内存的百分比(`accessMessageInMemoryMaxRatio=40%`),会推荐Consumer从Slave
 Broker中去读取数据,降低Master Broker的IO。
+
+#### 3.5 性能调优问题
+
+异步刷盘建议使用自旋锁,同步刷盘建议使用重入锁,调整Broker配置项`useReentrantLockWhenPutMessage`,默认为false;异步刷盘建议开启`TransientStorePoolEnable`;建议关闭transferMsgByHeap,提高拉消息效率;同步刷盘建议适当增大`sendMessageThreadPoolNums`,具体配置需要经过压测。
+
+#### 3.6 在RocketMQ中msgId和offsetMsgId的含义与区别
+
+我们使用RocketMQ完成生产者客户端消息发送后,通常会看到如下日志打印信息:
