问答 实现分布式session过程中遇到的一些问题
发布于 2780天前 作者 zrh091110225 6324 次浏览 复制 上一个帖子 下一个帖子
标签: 无

实现方式：
1. 主模块定义过滤器式的Session提供者为：@SessionBy(ShiroSessionProvider.class)
2. 实现方式：
自己实现一个RedisSessionDAO extends CachingSessionDAO
重写了doCreate(),readSession(),doReadSession(),doUpdate(),doDelete()通过redis读写session的方法

遇到的问题是：
如果是一台机器的话运行正常，如果两台机器均衡负载的时候会导致/home,/login页面循环重定向，查了很久也没有太多的头绪...

同一个redis进程吗

来自炫酷的 NutzCN

@wendal
搭了一个3mater,3slave的reids集群
代码中用的是redis.clients.jedis.JedisCluster操作redis的

把集群先撤了, 先把单机搞通.

PS: 为啥需要实现CachingSessionDAO, 像nutz.cn这样只实现CacheManager也是个办法

@wendal ok，你是觉得有可能是因为集群组从同步延迟导致？
恩。。。确实是可以只实现。
我试试

@wendal 有没有例子？ 我们贴下代码，帮忙看下有什么问题

本站的源码就是例子... 链接在页脚.

你看EnterpriseCacheSessionDAO, 几乎什么都不干.

循环重定向的问题还是木有解决，悲剧啊。
远程调试的时候无法重现问题...本地跟代码的时候也看不出问题...
现在知道的是调用/private/home接口的时候通过SecurityUtils.getSubject();拿到的身份认证subject.isAuthenticated()是false

服务信息

两台ECA均衡负载
单机redis缓存session

现象：

1.配置两台机器负载权重50，50。这样基本就是循环重定向。
2.配置两台机器负载权重20，80 。可以减少循环重定向出现的概率，但是避免不了问题。
3.先配置机器负载权重0:100然后登陆，再重新配置机器负载权重100:0不需要重新登陆。
4.本地起服务然后登陆，关闭服务重新起一次不需要重新登陆。

实现方式（参考的nutz.cn）：

使用ComboCacheManager替换了默认的CacheManager。
拷贝EnterpriseCacheSessionDAO替换CachingSessionDAO。

@wendal 呃...可以干掉试一下?

试啊... 尽量减少干预

我刚刚用论坛的代码测试一下, 环境如下:

win7 sp1 x64
tomcat 9.0.0.M9 分别位于D盘和E盘
redis 3.2 单机
mysql 5.7 单机

启动两个tomcat, 并使用nginx做简单均衡:

	upstream nutzbook {
		server 127.0.0.1:5080; # tomcat A
		server 127.0.0.1:6080; # tomcat B
	}

    server {
        listen       80;
        server_name  localhost;
        location / {
                        proxy_http_version 1.1;
                        client_max_body_size 1024m;
                        proxy_pass http://nutzbook;
                        proxy_set_header Host $http_host;
                        proxy_set_header        X-Real-IP       $remote_addr;
                        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
						proxy_set_header Upgrade $http_upgrade;
						proxy_set_header Connection $http_connection;
        }
    }

然后访问 http://127.0.0.1 登录, 刷新N次, 看到两个tomcat均有日志, 登录状态也没有变化.

@wendal刚试了一下把rememberMe相关的配置都去了，还是不行

rememberMeCookie = org.apache.shiro.web.servlet.SimpleCookie
rememberMeCookie.name=remember
rememberMeCookie.maxAge = 604800
rememberMeCookie.httpOnly = true
rememberMeManager = org.apache.shiro.web.mgt.CookieRememberMeManager
rememberMeManager.cookie = $rememberMeCookie
securityManager.rememberMeManager = $rememberMeManager

nutzcn论坛演示session集群

@wendal 我是在nutzwk项目上增量开发实现集群的，然后搬的nuzt-book的cachemanager的代码。之前有人实现过nutzwk的集群吗？

@wendal 我们用的是nutzwk框架，NutDaoRealm和登入的controller没有修改，只是修改了session的缓存，炒的是nutzbook

我猜测的流程是这样:

假设每次请求都轮换服务器(50/50配置)

访问A机器的login链接, 得到Session X, 然后该Session是已经登录成功的,所以, 重定向到home链接

这时候,分配到B机器, 访问home链接,得到Session Y, 但 X != Y, 且Y是没有登录的Session, 所以又触发重定向到login链接

最后,因为是第三次访问,所以又跳到A机器, 得到Session X.

问题的关键是 X != Y 即两台机器得到的Session不一样(猜测).

所以呢, 首先,要验证一下home和login在两台机器上的session id是否一致.

如果一致,那么肯定是Session的持久化有问题. PS: Shiro的Session持久化必须用JDK原生的序列化,不可用第三方的!!!

如果不一致,那么就是CacheManager的问题了.

@wendal 兽总，很奇怪，home和login打印出来的session id多是空的，不清楚啥原因
2016-09-19 13:05:35,599 cn.wizzer.modules.back.sys.controllers.LoginController.login(LoginController.java:62) INFO - login session id=
2016-09-19 13:05:42,564 cn.wizzer.modules.back.sys.controllers.HomeController.home(HomeController.java:36) INFO - home session id=

打印代码
@At("")
@Ok("beetl:/private/sys/home.html")
@RequiresAuthentication
public void home() {
log.infof("home session id=", SecurityUtils.getSubject().getSession().getId());
//SecurityUtils.getSubject().getSession().setTimeout(1000);
}

    @At("")
@Ok("re")
@Filters
public String login() {
    Subject subject = SecurityUtils.getSubject();
    log.infof("login session id=",subject.getSession().getId());
    if (subject.isAuthenticated()) {
        return "redirect:/private/home";
    } else {
        return "beetl:/private/sys/login.html";
    }
}

序列化的问题，检查session序列化到redis的代码

来自炫酷的 NutzCN

@wendal RedisCache这个是拿的是nutzbook的代码 代码如下，用的是jdk的序列化

@Override
public V get(K key) throws CacheException {
    if (DEBUG)
        log.infof("GET name=%s key=%s", name, key);
    try (Jedis jedis = _pool().getResource()) {
        byte[] buf = jedis.hget(nameByteArray, key.toString().getBytes());
        if (buf == null)
            return null;
        return (V) toObject(buf);
    }
}


    @Override
public V put(K key, V value) throws CacheException {
    if (DEBUG)
        log.infof("SET name=%s key=%s", name, key);
    // TODO 应使用pipeline
    //V prev = get(key);
    try (Jedis jedis = _pool().getResource()) {
        jedis.hset(nameByteArray, key.toString().getBytes(), toByteArray(value));
        return null;
    }
}


 public static final byte[] toByteArray(Object obj) {
    try {
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        ObjectOutputStream oos = new ObjectOutputStream(out);
        oos.writeObject(obj);
        oos.flush();
        oos.close();
        return out.toByteArray();
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }    }

public static final Object toObject(byte[] buf) {
    try {
        ByteArrayInputStream ins = new ByteArrayInputStream(buf);
        ObjectInputStream ois = new ObjectInputStream(ins);
        return ois.readObject();
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}

贴当前的shiro.ini

@qq_d6c9c504 sessionIdCookie怎么还有其他域名的信息？干掉

来自炫酷的 NutzCN

@wendal 你看下后面发的，已经注释掉了

为啥rememberMeCookie还在

来自炫酷的 NutzCN

@wendal 刚才我们干掉了也不行，后来我加日志发了一下覆盖了，我们在干掉试试

@wendal 干掉了也不行，还是一样sessionid为空

对比了一下nutzcn的shiro.ini, 似乎你们除了sessionIdGenerator之后都一样了

@wendal 是的，我们整了好几天也没发现有啥问题，登入进去之后，发现有时候使用里面的功能会重定向，大部分时候功能使用的时候不会重定向
