这是来自文档......
if __name__ == "__main__":
# Interactive mode
run(host='localhost', port=8049, debug=True)
这是我得到的错误.我错过了什么？
Bottle server starting up (using WSGIRefServer(debug=True))...

Hit Ctrl-C to quit.

我有服务器问题让兔子集群.
我在ec2上启动了两个节点.
在第一个启动的节点上,我这样做.
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app
I boot another node.
sudo service rabbitmq-server stop
#Copy cookie from the first server booted
sudo su - -c 'echo -n "cookie" > /var/lib/rabbitmq/.erlang.cookie'
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl cluster rabbit@server1
1)sever1正在运行2)需要打开哪些端口？我有22,4369,5672
sudo rabbitmqctl cluster rabbit@aws-rabbit-server-east-development-20121102162143
Clustering node 'rabbit@aws-rabbit-server-east-development-20121103033005' with ['rabbit@aws-rabbit-server-east-development-20121102162143'] ...

那些文档可能会遗漏什么,或者我错过了什么？
我有一个列表,看起来像这样:
data = [
[u'2012-10-31', '20', 9801, '0', '0', '0', '0'],
[u'2012-10-31', '21', 9266, '0', '0', '0', '0'],
[u'2012-10-31', '22', 10526, '0', '0', '0', '0'],
[u'2012-10-31', '23', 9570, '0', '0', '0', '0'],
[u'2012-10-31', '1', 5256, '0', '0', '0', '0'],
[u'2012-10-31', '0', 5020, '0', '0', '0', '0'],
# and so on...
]
我需要先按日期排序,这是索引0和小时是索引1.如何在python中进行排序？
我在mysql中有一个datetime字段.
我需要在这两种日期范围之间选择YYYY-MM-DD HH格式
"2012-12-20 10"和"2012-12-23 15"
我如何在mysql中执行此操作,其中utcdt是我的datetime字段？
SELECT DISTINCT utcdt
FROM rtb
WHERE
utcdt>=UNIX_TIMESTAMP("2012-12-20 10") and utcdt<=UNIX_TIMESTAMP("2012-12-23 15")
我有一个如下所示的列表:
list=[
('2013-01-04', u'crid2557171372', 1),
('2013-01-04', u'crid9904536154', 719677),
('2013-01-04', u'crid7990924609', 577352),
('2013-01-04', u'crid7990924609', 399058),
('2013-01-04', u'crid9904536154', 385260),
('2013-01-04', u'crid2557171372', 78873)
]
问题是第二个col具有dup id但不同的计数.我需要有一个列表来汇总计数,所以列表看起来像这样.在python中有一组cluase吗？
list=[
('2013-01-04', u'crid9904536154', 1104937),
('2013-01-04', u'crid7990924609', 976410),
('2013-01-04', u'crid2557171372', 78874)
]
我无法在ubuntu 12.04上更改mysql的默认目录.
我尝试了什么:
服务mysql停止
我移动了/ var/lb/mysql/data/mysql
datadir =/data/mysql #my.cnf
服务mysql启动
输出:
/ var/log/mysql #service mysql start start:作业无法启动
当我尝试重新启动时:
/var/log/mysql# service mysql start
start: Job failed to start
我正在尝试使用 sed 替换文件中的路径。
sudo sed 's/a/b/g' -i /tmp/test
然而变量是
a = /var/lib and
b = /data/lib
如何逃脱斜线？
我正在使用python 2.7并用于requests获取网页.
我想知道获取的对象是否已更改.
r = requests.get(url,headers=None,proxies=None,timeout=int(parms['timeout']))
html = r.text
if checksum(html)!=checksum_last:
then do something
else:
do nothing
我将校验和保存在数据库中.如何创建校验和？
谢谢
我知道如何将DF保存为csv文件.我想将csv作为字符串,我不想保存,然后加载.
df.to_csv('test.csv',index=True)
my_csv = open('test.csv').read()
print type(my_csv)
<type 'str'>
相反,我会评价以下内容:
my_csv = df.to_csv()
如何在Angular 2 RC4中获取查询参数？我尝试了文档,但没有任何意义.
例如
http://localhost:3000/models/initials/mid_c1e1c31e6eff42f1982af4124a823b36?test=4
在ngOnInit如何获取参数的值test？
private sub: Subscription;
ngOnInit() {
this.sub = this.route.params.subscribe(params => {
console.log(params);
let id = params['test'];
console.log(id);
});
}
这是我导航到我想要获取查询参数的路线:
this._router.navigate(['models/initials/'+model_id+'?test=4']);
