Error setting TTL index on collection :sessions
好蛋疼啊 我在公司不会报错··自己在家做会报这个错误····· 卡住了 网上找了··没有明确的答复啊·· 求帮助 app.use(session({ saveUninitialized: true, resave: false, secret: settings.cookieSecret, key: settings.db,//cookie name cookie: {maxAge: 1000 * 60 * 60 * 24 * 30},//30 days store: new MongoStore({ db: settings.db, host: settings.host, port: settings.port }) }));

Error: Error setting TTL index on collection : sessions
我也是同样的报错,不能设置这个索引.
然后我直接注释了那段代码,
然而并没有什么影响.
self.collection = collection;
// Make sure we have a TTL index on "expires", so mongod will automatically
// remove expired sessions. expireAfterSeconds is set to 0 because we want
// mongo to remove anything expired without any additional delay.
self.collection.ensureIndex({expires: 1}, {expireAfterSeconds: 0}, function(err, result) {
// nothing
// none of my bussines?
// 只是为了自动清楚过期会话嘛,mongodb版本更新后不一样了?
// https://github.com/nswbmw
/* if (err) {
throw new Error('Error setting TTL index on collection : ' + self.db_collection_name);
} */
callback && callback(self.collection);
}); db.sessions.ensureIndex({expires: 1}, {expireAfterSeconds: 0});
- 在shell中自行建立索引是可行的.
self.collection = collection;
- 是不是这个collection的指向不是sessions?
mongdb 2.6X
3.宿主机3.0和mongolab 2.6版本都会报这个错误. 4.按照(3)创建的索引起不到自动清除session的作用,session一直在增加.
