安装
准备：
jdk1.8
maven 3.3.9以上，我这里用的是3.3.9
登录linux服务器
下载rocketMq安装包
wget http://mirrors.tuna.tsinghua.edu.cn/apache/rocketmq/4.3.0/rocketmq-all-4.3.0-source-release.zip
unzip rocketmq-all-4.3.0-source-release.zip
安装maven
wget http://mirrors.cnnic.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz
配置maven环境变量
MAVEN_HOME=/usr/local/maven
export MAVEN_HOME
export PATH=${PATH}:${MAVEN_HOME}/bin
生效配置文件
source /etc/profile
检查maven是否成功
^C[root@supervisordruid1 ~]# mvn -v
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
Maven home: /root/maven/apache-maven-3.3.9
Java version: 1.7.0_51, vendor: Oracle Corporation
Java home: /usr/local/jdk/jdk1.7.0_51/jre

OS name: "linux", version: "2.6.32-754.3.5.el6.x86_64", arch: "amd64", family: "unix"
通过maven编译部署
cd rocketmq-all-4.3.0-source-release
mvn -Prelease-all -DskipTests clean install -U
可能报错
[root@supervisordruid1 rocketmq-all-4.3.0]# mvn -Prelease-all -DskipTests clean install -U
-bash: bin/mvn: 没有那个文件或目录
将jdk改为1.8

进入distribution/target/apache-rocketmq目录
cd distribution/target/apache-rocketmq
启动的时候先启动 namesrv，然后启动 broker
启动 NameServer：
先进入 RocketMQ 安装目录下的 distribution/target/apache-rocketmq 目录
# 启动命令,并且常驻内存
$ nohup sh bin/mqnamesrv & 或者 sh mqnamesrv
# 查看启动日志能看到：The Name Server boot success字样则成功
$ tail -f ~/logs/rocketmqlogs/namesrv.log
nohup sh mqnamesrv & ：属于后台启动
sh mqnamesrv ：属于终端启动，直接输出日志信息，按 ctrl+c 可直接关闭退出
启动 Broker
# 启动命令，并且常驻内存:注意ip地址要配置成为服务的ip地址，保证地址以及端口能够访问
> nohup sh bin/mqbroker -n localhost:9876 &
# 查看启动日志
> tail -f ~/logs/rocketmqlogs/broker.log
nohup sh bin/mqbroker -n localhost:9876 & ：属于后台启动
sh bin/mqbroker -n localhost:9876 ：属于终端启动，直接输出日志信息，按 ctrl+c 可直接关闭退出
我启动的时候报错：
[root@supervisordruid2 apache-rocketmq]# sh bin/mqbroker -n localhost:9876
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000005c0000000, 8589934592, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 8589934592 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /root/rocketMq/rocketmq-all-4.3.0/distribution/target/apache-rocketmq/hs_err_pid7473.log
[root@supervisordruid2 bin]# vi runserver.sh
找到如下配置，进行修改
JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
|
|
|
JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn125m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
[root@supervisordruid2 bin]# vi runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"
找到如下配置，进行修改
|
|
|
JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn125m"
然后再次启动 broker 时就成功了,broker 注册到了 nameserver 上了（localhost:9876
[root@supervisordruid2 apache-rocketmq]# sh bin/mqbroker -n localhost:9876
The broker[supervisordruid2, 172.17.42.1:10911] boot success. serializeType=JSON and name server is localhost:9876

我这里的原因是因为防火墙没开
vi /etc/sysconfig/iptables
添加
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
开启防火墙报错：
iptables: Applying firewall rules: iptables-restore v1.4.7: no command specified
Error occurred at line: 26
[root@supervisordruid2 apache-rocketmq]# service iptables restart
iptables: Setting chains to policy ACCEPT: filter nat [ OK ]
iptables: Flushing firewall rules: [ OK ]

iptables: Applying firewall rules: iptables-restore v1.4.7: no command specified
Error occurred at line: 26
Try `iptables-restore -h' or 'iptables-restore --help' for more information.
[FAILED]
因为防火墙的配置文件在修改的过程中多了回车空格导致的。
通过命令查看防火墙状态
[root@supervisordruid2 apache-rocketmq]# /etc/init.d/iptables status
Table: filter
Chain INPUT (policy ACCEPT)
num target prot opt source destination
1 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:9876

5 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:9876
之后重新启动rocket produer和consumer
运行还是会报错：rocketmq org.apache.rocketmq.remoting.exception.RemotingConnectException:connect to failed
rocketmq org.apache.rocketmq.remoting.exception.RemotingConnectException:connect to failed
这是由于跨域造成的:
修改服务器中broker的配置，添加服务器IP(公网)即可
vim /home/prod/rocketmq-all-4.3.0/distribution/target/apache-rocketmq/conf/broker.conf
新增一行:
brokerIP1=xx.xx.xx.xx # 你的公网IP，即你的mq安装的哪个服务器的ip，不是你java程序的ip
然后重启 mqnamesrv，记得先杀死进程
> nohup sh bin/mqnamesrv &
> tail -f ~/logs/rocketmqlogs/namesrv.log
The Name Server boot success...
然后重启Broker， 记得先杀死进程
注意，重点是: -c conf/broker.conf
> nohup sh bin/mqbroker -n localhost:9876 -c conf/broker.conf &
> tail -f ~/logs/rocketmqlogs/broker.log
The broker[%s, 172.30.30.233:10911] boot success..
至此终于能够正常启动了，producer和consumer正常。
producer 输出：

consumer输出
