Let's first go to / etc/hosts to add information

vim /etc/hosts

Add the following information:

Pass apache-rocketmq.tar.gz to / usr/local/software through XFTP tool

Then add / usr / local / Apache rocketmq directory, and extract Apache rocketmq.tar.gz to this directory

[root@bogon apache-rocketmq]#  mkdir /usr/local/apache-rocketmq && tar -zxvf apache-rocketmq.tar.gz -C /usr/local/apache-rocketmq

Create another soft connection

[root@bogon local]# ln -s apache-rocketmq rocketmq

Create storage path

[root@bogon local]# mkdir /usr/local/rocketmq/store
[root@bogon local]# mkdir /usr/local/rocketmq/store/commitlog
[root@bogon local]# mkdir /usr/local/rocketmq/store/consumequeue
[root@bogon local]# mkdir /usr/local/rocketmq/store/index

Change profile:

vim /usr/local/rocketmq/conf/2m-2s-async/broker-a.properties

Change to the following:

#Cluster name
brokerClusterName=rocketmq-cluster
#broker name. Note that different configuration files are filled in differently
brokerName=broker-a
#0 for Master, > 0 for Slave
brokerId=0
#nameServer address, semicolon split

After modifying the log configuration, we go to the usr/local directory

[root@rocketmq-nameserver1 local]# mkdir -p /usr/local/rocketmq/logs
[root@rocketmq-nameserver1 local]# cd /usr/local/rocketmq/conf && sed -i 's#${user.home}#/usr/local/rocketmq#g' *.xml

Then modify the parameters of the startup script

[root@rocketmq-nameserver1 bin]# vim /usr/local/rocketmq/bin/runbroker.sh
[root@rocketmq-nameserver1 bin]# vim /usr/local/rocketmq/bin/runserver.sh

Change the memory configuration in both files to 1G

We can start rocketmq now. The starting sequence is to start NameServer first and then broker server

First, enter the directory / usr/local/rocketmq/bin and enter the following command

[root@rocketmq-nameserver1 bin]# nohup sh mqnamesrv &

When we input jsp, if namesrvstartup appears, the NameServer starts successfully

Then start the broker server by entering the following command

[root@rocketmq-nameserver1 bin]# nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-2s-async/broker-a.properties >/dev/null 2>&1 &

Enter jps again, and you can see that the broker server is started
