Nginx+Tomcat动静分离及Nginx优化
目的:nginx处理用户请求的静态页面,tomcat处理用户请求jsp页面,来实现动态分离,nginx处理静态页面效率远高于tomcat,这样一来就能更好的提高并发,处理性能。
准备软件:
下载jdk1.7:http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
下载tomcat8.0:http://tomcat.apache.org/download-80.cgi
下载nginx1.4.4:http://nginx.org/en/download.html

#默认tomcat是root身份运行的,这样不安全,我们设置来用普通用户
