2, the installation package uploaded to the system linux / opt directory and extract the
cd / opt into / opt directory
rz -y open upload window
Upload window interface shown below:
3, a new directory in the root directory myActivemq
cd / into the root directory
Create a directory mkdir myActivemq
4, the compressed copied to their new directory and decompress
cp /opt/apache-activemq-5.15.10-bin.tar.gz / myActivemq archive copy
cd /myActivemq/
tar -zxvf apache-activemq-5.15.10-bin.tar.gz decompressor
The decompressed directory contents below:
Unzip into the directory:

To see what there is inside:
ls
among them:
lib: storage jar package variety, such as the need for persistent connections mysql database, need to put mysql driver jar package
bin: to store a variety of programs
5, ordinary start activemq program
