多实例部署

配置和执行文件分开，tomcat安装目录仅留下bin和lib目录，instance目录下放原conf，新建bin,logs,webapps,work空目录

instance/bin 创建 start-instance.sh

export CATALINA_HOME=/usr/local/tomcat/tomcat7
export CATALINA_BASE=/usr/local/tomcat/instance
/usr/local/tomcat/tomcat7/bin/startup.sh

instance/bin 创建 stop-instance.sh

export CATALINA_HOME=/usr/local/tomcat/tomcat7
export CATALINA_BASE=/usr/local/tomcat/instance
/usr/local/tomcat/tomcat7/bin/shutdown.sh

Performance

设置Jasper development为false

Is Jasper used in development mode? If true, the frequency at which JSPs are checked for modification may be specified via the modificationTestInterval parameter.
