阿里云安装RocketMQ

• 说明：

  • 我的阿里云是centos 6.9
  • jdk 1.8.0_192-b12（安装教程参照：https://www.cnblogs.com/kingsonfu/p/9801556.html）
  • maven apache-maven-3.6.1（安装教程参照：https://www.cnblogs.com/yangyuke1994/p/10592055.html）　　

1. 安装jdk，配置环境变量

2. 安装maven，配置环境变量

3. 下载部署RocketMQ

   • 新建rocketmq目录，下载依赖 wget http://mirror.bit.edu.cn/apache/rocketmq/4.5.2/rocketmq-all-4.5.2-source-release.zip
   • 解压 unzip rocketmq-all-4.5.2-source-release.zip
   • 如果提示 -bash: unzip: command not found，说明没有找到命令，安装unzip即可 yum install -y unzip zip
   • 进入 rocketmq-all-4.5.2-source-release 目录构建项目 mvn -Prelease-all -DskipTests clean install -U （构建过程比较耗时，需要下载很多依赖）

4. 启动namesrv

   • 修改runserver.sh的默认内存（如果是土豪配置，可以忽略） /rocketmq/rocketmq-all-4.5.2-source-release/distribution/target/rocketmq-4.5.2/rocketmq-4.5.2/bin

     #这是RocketMQ默认值
     JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
     
     #这是修改后的值
     JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

   • 启动服务 nohup sh mqnamesrv > /dev/null 2>&1 &
   • 查看namesrv服务日志，确认是否成功启动，默认日志路径 ${user.home}/logs/rocketmqlogs/namesrv.log，如下所示表明启动成功

     2019-08-28 10:42:11 INFO main - tls.client.authServer = false
     2019-08-28 10:42:11 INFO main - tls.client.trustCertPath = null
     2019-08-28 10:42:12 INFO main - Using OpenSSL provider
     2019-08-28 10:42:12 INFO main - SSLContext created for server
     2019-08-28 10:42:12 INFO main - Try to start service thread:FileWatchService started:false lastThread:null
     2019-08-28 10:42:12 INFO main - The Name Server boot success. serializeType=JSON
     2019-08-28 10:42:12 INFO FileWatchService - FileWatchService service started
     2019-08-28 10:42:12 INFO NettyEventExecutor - NettyEventExecutor service started

5. 启动broker

   • 修改broker启动脚本的默认内存配置

     #这是默认值
     JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"
     
     #这是修改后的值
     JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512g"

   • 创建broker.conf配置文件，内容如下

     namesrvAddr={你自己的阿里云服务器外网IP或者内网IP}:9876
     brokerIP1={你自己的阿里云服务器外网IP}
     brokerName=james
     brokerClusterName=DefaultCluster
     brokerId=0
     autoCreateTopicEnable=true
     autoCreateSubscriptionGroup=true

   • 启动服务 nohup sh mqbroker -c broker.conf> /dev/null 2>&1 &

   • 查看broker启动日志

   • 出现上面这种情况，首先去阿里云上检查是否对外暴露了9876端口，如果没有，在阿里云上添加对外暴露9876端口（安全组 -> 配置规则 -> 添加安全组规则）
   • 添加完毕，后重启broker服务，提示如下，就说明启动成功

     2019-08-28 11:10:54 INFO PullRequestHoldService - PullRequestHoldService service started
     2019-08-28 11:10:54 INFO brokerOutApi_thread_1 - register broker[0]to name server 你的阿里云服务器IP:9876 OK
     2019-08-28 11:10:54 INFO main - The broker[james, 47.105.147.14:10911] boot success. serializeType=JSON and name server is 你的阿里云服务器IP:9876

   • 输入 jps 命令，查看Java进程

     #说明 NamesrvStartup，BrokerStartup两个服务启动成功
     21251 Jps
     21175 BrokerStartup
     20989 NamesrvStartup

6. 特别注意：

   • nameserver端口默认为 9876
   • broker监听端口默认为 10911
   • 这两个端口务必一定要在阿里云安全组里对外暴露

7. 关闭namesrv服务 sh mqshutdown namesrv，关闭broker服务 sh mqshutdown broker

8. 安装 rocketmq-console 控制台

• • https://github.com/apache/rocketmq-externals.git

  • 选择 rocketmq-console 模块中加入maven，修改resources目录下的application.properties文件

    server.contextPath=
    server.port=8080
    
    ### SSL setting
    #server.ssl.key-store=classpath:rmqcngkeystore.jks

    #if this value is empty,use env value rocketmq.config.namesrvAddr  NAMESRV_ADDR | now, you can set it in ops page.default localhost:9876
    rocketmq.config.namesrvAddr=你的阿里云服务器IP:9876
    #if you use rocketmq version < 3.5.8, rocketmq.config.isVIPChannel should be false.default true
    rocketmq.config.isVIPChannel=false
    #rocketmq-console's data path:dashboard/monitor
    rocketmq.config.dataPath=/tmp/rocketmq-console/data
    #set it false if you don't want use dashboard.default true
    rocketmq.config.enableDashBoardCollect=true
    #set the message track trace topic if you don't want use the default one
    rocketmq.config.msgTrackTopicName=james
    rocketmq.config.ticketKey=ticket
    
    #Must create userInfo file: ${rocketmq.config.dataPath}/users.properties if the login is required
