Install RocketMQ

Here we use the source code to compile and install. For reference, pull the source code from github to compile, and then use maven to compile

Pulling code and compiling through maven

# Select git code download directory and pull the source code (you can pull the branch of the latest version: release-4.1.0-incoming)
$ git clone -b release-4.1.0-incubating https://github.com/apache/incubator-rocketmq.git
# Switch to file directory
$ cd incubator-rocketmq
# Compile with maven, download the jar package and wait for the compilation to succeed
$ mvn -Prelease-all -DskipTests clean install -U
# Switch to the bin directory of the compiled directory to prepare to start the server
$ cd distribution/target/apache-rocketmq/bin

Start name Server (cluster can be set)

# Start the command and stay in memory
$ nohup sh mqnamesrv &
# If you check the startup log, you can see that The Name Server boot success is successful
$ tail -f ~/logs/rocketmqlogs/namesrv.log

Start broker (cluster, master and slave can be set)

# Start the command and stay in memory: note that the ip address should be configured as the ip address of the service to ensure that the address and port can be accessed (official problem)
$ nohup sh mqbroker -n "192.168.1.113:9876" -c ../conf/2m-noslave/broker-a.properties > broker.out &
# When I started, I reported an error because the corresponding runbroker configuration set the memory size of the virtual machine to 4g. I didn't have enough memory, so I changed it to 2g as follows
JAVA_OPT="${JAVA_OPT} -server -Xms2g -Xmx2g -Xmn1g"
# View startup log
$ tail -f ~/logs/rocketmqlogs/broker.log 

Close RcocketMQ related services

# Stop broker service
$ sh mqshutdown broker
# Customizing the nameserver service
$  sh mqshutdown namesrv

Sending and receiving messages to MQ

# Execute under the bin directory to introduce the server address into the environment variable
$ export NAMESRV_ADDR=192.168.1.113:9876
# Case producer production message implemented by java code
$ sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
# Using java code to realize case consumer consumption message
$ sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer

Monitoring MQ

# Call command monitoring in bin directory of target
$ sh mqadmin clusterList -n 192.168.1.113:9876
