本文档详细介绍了Nginx配置文件nginx.conf的设置方法，包括服务进程数量、错误日志记录、多路复用IO、并发连接数等参数。此外，还深入探讨了基于Spring框架的Shiro-Redis配置，包括Shiro的安全管理、匿名过滤、登录认证、会话管理和缓存管理等关键组件。

nginx配置(nginx.conf)

#服务进程数量，一般等于CPU数量
worker_processes  1;

error_log  /save/savefe-nginx-logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
	#epoll是多路复用IO(I/O Multiplexing)中的一种方式,但是仅用于linux2.6以上内核,可以大大提高nginx的性能.Linux建议使用epoll，FreeBSD建议使用kqueue.
    use epoll;
	#一个worker_processe允许的最近并发连接数量
    worker_connections  1024;
}

 tomcat配置（没啥配置，就配了个JVM,catalina.sh）

 

JAVA_OPTS="-Xms1g -Xmx1g -Xmn512m -XX:PermSize=256m -XX:MaxPermSize=512m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+UseCMSCompactAtFullCollection -XX:CMSFullGCsBeforeCompaction=0 -XX:CMSInitiatingOccupancyFraction=70"

 

shiro-redis配置(基于spring)

 

1、maven

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.2.4</version>
</dependency>

<dependency>
    <groupId>org.crazycake</groupId>
    <artifactId>shiro-redis</artifactId>
    <version>2.4.2.1-RELEASE</version>
</dependency>

 2、beans-shiro-redis.xml
