to deploy the project to the Linux system :( premise: the jdk, tomcat, mysql are installed)
installed http services on Linux, the command:

service httpd start
setting boot command:
chkconfig httpd ON
View open state to start, the command:
chkconfig --list httpd

test:
Open the ip address of the page, enter the virtual machine server,
you can jump to the Apache 2 Test Page page, then prove http service installed.
Open eclipse myeclipse or
find the items you need to deploy a

whether the normal access success.
After a successful visit:
find projects ip address of the database connection,
the connection to the database ip address changed to: localhost or Linux ip address.
The database name to Linux in the corresponding database name,
and then transferred to the Linux form the corresponding database.
