我试图从命令行自动创建密码.我已经尝试过以下但仍然一直要求输入密码.
echo "test101" | htpasswd -c ~/temp/password admin
如何在htpasswd不输入密码的情况下从命令行生成自动化？
我从我的本地仓库删除了python .pyc文件,我认为我做的是从远程github删除.
我推动了所有变化.这些文件仍然在repo上,但不在我的本地机器上.如何从github仓库中删除文件？
我尝试了以下方法:
git rm classes/file.pyc
git add .
git
乃至:
git rm --cached classes/file.pyc
然后,当我尝试检出文件时,我收到此错误.
enter code here`error: pathspec 'classes/redis_ha.pyc' did not match any file(s) known to git.
我现在不知道还能做什么.截至目前,我有一个完全损坏的git repo.
似乎安装flask-login有问题.尽管使用下面的安装成功
pip install flask-login
我的app.py文件:
from flaskext.login import LoginManager
lm = LoginManager()
我收到此错误:
ImportError: No module named login
那我该如何解决呢
日志存储对我来说是100%的灾难.我在同一台机器上使用LS 1.4.1和ES 1.02.
以下是我启动logstash索引器的方法:
/usr/local/share/logstash-1.4.1/bin/logstash -f /usr/local/share/logstash.indexer.config
input {
redis {
host => "redis.queue.do.development.sf.test.com"
data_type => "list"
key => "logstash"
codec => json
}
}
output {
stdout { }
elasticsearch {
bind_host => "127.0.0.1"
port => "9300"
}
}
ES我设置:
network.bind_host: 127.0.0.1
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["127.0.0.1:9300"]
哇..这就是我得到的:
/usr/local/share/logstash-1.4.1/bin/logstash -f /usr/local/share/logstash.indexer.config
Using milestone 2 input plugin 'redis'. This plugin should be stable, but if you see strange behavior, please let us know! For more information on plugin milestones, see http://logstash.net/docs/1.4.1/plugin-milestones …我没有获得redis node.js文档以使用redis auth.
根据这个例子:
var redis = require("redis"),
client = redis.createClient();
// This command is magical. Client stashes the password and will issue on every connect.
client.auth("somepass");
在我的代码中,我有以下内容:
var redis = require("redis");
r = redis.createClient(6379,'xxx.xxx.xxx.xxx');
r.auth("yyyyyyyy");
app.get('/', function(req, res){
r.set("foo", 'bar');
res.writeHead(200, {'Content-Type': 'image/gif'});
res.end('Hello');
});
这是我得到的错误:
Express server listening on port 8070 in development mode
/home/ubuntu/workspace/rtbopsConfig/rtbServers/rtbNodejsServer/node_modules/redis/index.js:468
throw callback_err;
^

at …我是Chef,ruby,ruby DSL和erb的新手.我来自python.在ruby erb模板中,我想做这样的事情.
<% if node[:monit][:server]=='nginx' -%>
ALL OF MY NGINX TEXT
<% end -%>
<% if node[:monit][:server]=='redis' -%>
ALL OF MY REDIS TEXT
<% end -%>
很明显,我错过了正确的语法.
谢谢
我正在使用Flask.
我正在做一个ajax帖子,我需要检查是否存在密钥.
我尝试了这个,但没有奏效.
if request.args.has_key('campaign_id_crid'):
print True
什么是更好的测试方法？
我试图在模板语法中评估下面的数组:
FAIL
{{ cols.length }}
我得到以下错误.
platform-browser.umd.js:1900 ORIGINAL EXCEPTION: TypeError: Cannot read property 'length' of undefined
但我会迭代所以我知道该部分有效:
SUCCESS
<th *ngFor="let h of cols">
{{h}}
</th>

我正在尝试使用以下内容在hdfs中列出我的目录:
ubuntu@ubuntu:~$ hadoop fs -ls hdfs://127.0.0.1:50075/
ls: Failed on local exception: com.google.protobuf.InvalidProtocolBufferException:
Protocol message end-group tag did not match expected tag.;
Host Details : local host is: "ubuntu/127.0.0.1"; destination host is: "ubuntu":50075;
这是我的/ etc/hosts文件
127.0.0.1 ubuntu localhost
#127.0.1.1 ubuntu
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
如何正确使用hdfs://列出我的目录？
