1.Download the MySQL JDBC driver from  http://www.mysql.com/downloads/connector/j/5.1.html.

2.Extract the JDBC driver JAR file from the downloaded file. For example:

tar zxvf mysql-connector-java-5.1.31.tar.gz

3.Copy the JDBC driver, renamed, to the relevant host. For example:

$ sudo cp mysql-connector-java-5.1.31/mysql-connector-java-5.1.31-bin.jar /usr/share/java/mysql-connector-java.jar

If the target directory does not yet exist on this host, you can create it before copying the JAR file. For example:

$ sudo mkdir -p /usr/share/java/
$ sudo cp mysql-connector-java-5.1.31/mysql-connector-java-5.1.31-bin.jar /usr/share/java/mysql-connector-java.jar
