在SQL SERVER 2005下还原数据库 1、新建数据库A，右键还原数据库，此时目标数据库为A，选择备份文件B_db_201311040200.BAK，还原时提示“备份集中的数据库备份与现有的A数据库不同 ” 2、google一下，有人说是文件名不同，即B的数据库文件为B.MDF，要还原到A.MDF上，所以报错 3、删除A库，在根目录【数据库】上右键，还原数据库，先选择源文件，然后再目标数据库中会自动出现B，选择B之后即可还原成功 问题：如果要还原出一个名称不同的库该怎么处理？ 1)还原后修改名称？ 来源： oschina 链接： https://my.oschina.net/u/557089/blog/174087

今天跑的一个php脚本遇到了一个MySQL server has gone away问题的问题 原因是遍历循环生成excel并打包的时间过长，超过了mysql的 wait-timeout时间，导致mysql断开了链接。 两种方法可以解决： 1.增加你的 wait-timeout值，这个参数是在my.cnf(在Windows下台下面是my.ini）中设置，（这个值的单位是秒，意思是当一个数据库连接在10秒钟内没有任何操作的话，就会强行关闭） 2.检查 MySQL的链接状态，使其重新链接 //数据库操作类中间的一个函数 function ping(){ if(!mysql_ping($this->link)){ mysql_close($this->link); //注意：一定要先执行数据库关闭，这是关键 $this->connect(); } } $DB->ping();//导致数据库连接关闭,检查并重新连接 $threeResult = $DB->fetch_arrays($sql); 经过这样处理后，可以非常有效的解决MySQL server has gone away这样的问题，而且不会对系统造成额外的开销 来源： oschina 链接： https://my.oschina.net/u/188211/blog/162441

After writing some data to a redis server, I could read the data from a client. However, how can I find the data directory on the file system? Quickest method: use redis-cli. redis-cli config get dir If you have authentication configured, you will need to pass that in using -a password Replacing "password" with your password. Find your Redis configuration directory, probably /etc/redis . Then look in the config file called redis.conf and find the line that starts dir . It will look similar to this: dir /etc/redis/database This will do the job slowly but surely if you can't be bothered to look

I am trying to access localhost:8080 but it is showing me I need to enter user name and pass word. I remember messing up with the server some 4 months ago while I was trying to develop a web application and hosting my domain name on my pc, Unfortunately I become unsuccessful. While working with servlets I was tring some security features and till some time i did not see and of these pop up windows asking for authentication. I tried to enter the password that I was playing with but non of those are working. Is there anyway i could get out of this problem? This is http authentication. You can

I use a clode server to test my django small project , I type in manage.py runserver & ,and then I log out my cloude server ,I can visit mysite normally but when I reload my cloude server , I don't know how to stop the development server, I had to kill the process to stop it, is there anyway to stop the development? The answer is findable via Google -- and answered in other forums. Example solution is available on the Unix & Linux StackExchange site . To be explicit, you could do: ps auxw | grep runserver This will return the process and its respective PID, such as: de 7956 1.8 0.6 540204

My first question is, I often read about people using multiple dedicated servers to run their websites, and process queries from users. But how do they exactly do this? I mean, when I enter a domain name, a DNS resolves maps that to an IP address, but I am lost after that.. is there some kind of master/slave architecture there to load balance incoming requests amongst the (potentially) hundreds of servers? If that's the case, how do the various servers, share data (database for e.g.)? Will they be connected to the same hard disk? ultramonkey will give you a good description of how to load
