Install and use MySQL in activemq 5.5 in centos 6

Copy the file from .tar.gz to the/home/software/Apache-activemq directory and run the following command:

 

# Cd/home/software/Apache-activemq

# Tar zxvf apache-activemq-5.5.0-bin .tar.gz

# Cp-A apache-activemq-5.5.0/usr/local/activemq

# Cd/usr/local/activemq

 

I use MySQL as the storage of messages. Modify/usr/local/activemq/CONF/activemq. XML as follows:

Before starting, you need to create the database activemq and do not configure <property name = "poolpreparedstatements" value = "true"/> with reference to the activemq-jdbc.xml.

# Bin/activemq start

Open it in the browser: Send it to the message for testing. If the message can be sent normally, there should be no major problems.
