linux下安装rocketmq消息中间件

本项目安装需要事先安装maven项目

1.下载(/user/local目录下)

下载地址：https://github.com/apache/rocketmq

本地下载的tar包是基础包，只能通过maven打包可以打包出rocketmq启动的项目。会生成在/rocketmq-all-4.2.0/distribution/target目录下apache-rocketmq文件，里面包含启动文件

wget https://github.com/apache/rocketmq/archive/rocketmq-all-4.2.0.tar.gz

2.解压

tar -zxvf rocketmq-all-4.2.0.tar.gz

3.maven编译生成rocketmq依赖的架包(包含生成rocketmq启动的项目)在usr/local/rocketmq-all-4.2.0目录下

mvn -Dmaven.test.skip=true clean package install assembly:assembly   -p release-all  -u

mvn install:install-file -Dfile=lucene-analyzers-common-6.3.0.jar -DgroupId=org.apache.lucene -DartifactId=lucene-analyzers-common-6.3.0 -Dversion=6.3.0 -Dpackaging=jar

用该命令，上面两个命令有问题
mvn -Prelease-all -DskipTests clean install -U

最后显示编译完成

编译完成后发现在/usr/local/rocketmq-all-4.2.0/distribution/target目录下apache-rocketmq文件,所有启动的项目命令都在这个项目里面里

4.配置系统环境变量

vi /etc/profile

添加如下两行

export rocketmq=/usr/local/rocketmq-rocketmq-all-4.2.0/distribution/target/apache-rocketmq
export PATH=$PATH:$rocketmq/bin

5.让系统环境变量生效

source /etc/profile

6.启动mqnameserver(/usr/local/rocketmq-rocketmq-all-4.2.0/distribution/target/apache-rocketmq/bin目录下)

创建rocketmq日志文件夹(/usr/local/logs/rocketmqlogs文件)

cd /usr/local/logs/

mkdir rocketmqlogs

nohup sh mqnamesrv > ~/logs/rocketmqlogs/namesrv.log 2>&1 &

启动后 可根据ps -ef|grep rocketmq查看进程

root     18706 18702  0 20:22 pts/0    00:00:00 sh /usr/local/rocketmq-rocketmq-all-4.2.0/distribution/target/apache-rocketmq/bin/runserver.sh org.apache.rocketmq.namesrv.NamesrvStartup

root     18884 18657  0 21:31 pts/0    00:00:00 grep --color=auto rocketmq
[2]+  Exit 1                  nohup sh mqnamesrv > ~/logs/rocketmqlogs/namesrv.log 2>&1

7.启动mqbroker(/usr/local/rocketmq-rocketmq-all-4.2.0/distribution/target/apache-rocketmq/bin目录下)

nohup sh mqbroker -n localhost:9876 autoCreateTopicEnable=true > ~/logs/rocketmqlogs/broker.log 2>&1 &

注意：localhost可以换成你刚才启动mqnamesrv的ip
