包php5在Ubuntu 16.04 LTS上没有安装候选(Package php5 has no installation candidate on Ubuntu 16.04 LTS)
我已经将我的系统升级到ubuntu 16.04 LTS，现在我已经发布了这个更新的版本安装PHP 7并删除了PHP 5，如何在ubuntu 16.04 LTS上安装PHP 5.4？
我试过了：
sudo apt-get install php5我收到了这个错误：
Reading package lists... Done Building dependency tree Reading state information... Done Package php5 is not available but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package php5 has no installation candidateI have upgraded my system to ubuntu 16.04 LTS, now I have issue this newer version install PHP 7 and remove the PHP 5, How I can install PHP 5.4 on ubuntu 16.04 LTS?
I tried:
sudo apt-get install php5and I got this error:
Reading package lists... Done Building dependency tree Reading state information... Done Package php5 is not available but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package php5 has no installation candidate

使用类似Mongoid的ODM可以减轻您的痛苦。 将它添加到您的
Gemfile：gem 'mongoid'并运行
bundle install。 确保浏览安装指南以添加所有必要的配置。 然后在您的模型/类中包含以下行：class Product include Mongoid::Document ... end您将能够立即查询像
Product.find(id)这样的记录。Using an ODM like Mongoid will ease your pain. Add it to your
Gemfile:gem 'mongoid'and run
bundle install. Make sure you skimmed through the installation guide to add all the necessary configs. Then include the following line to your model/class, say:class Product include Mongoid::Document ... endYou'll be able to query the records like
Product.find(id)right after.

mongo db中的会话表(session table in mongo db)[2021-09-09]
TTL是好的，然而所有修复都没有。 --repair不是设计为在数据库上定期运行，实际上可能每3个月或其他一次。 它会执行许多内部操作，如果经常运行，会严重损害服务器性能。 现在关于在这样的环境中重用磁盘空间; 删除记录时，它将释放“阻止”。 如果另一个文档适合该“块”，它将重用该空间，否则它将实际创建一个新的范围，意味着一个新的“块”又名更多的空间。 因此，如果你想在这里节省磁盘空间，你需要确保文件不会相互超过，幸运的是你有一个相对静态的模式： { _id: {}, token: {}, ... -
