# Service Tomcat restart
2. modify the configuration file
# Vim/usr/local/tomcat/CONF/server. xml
<Host name = "localhost" appbase = "webapps"
Unpackwars = "true" autodeploy = "true"> specify the default site location
<Context Path = "/test" docbase = "/usr/local/tomcat/webapps/test" reloadable = "true"> Configuration/test directory
