是否可以在RHEL 5上打开所有MySQL-5.6并安装MySQL-5.1
是否可以在RHEL 5上打开所有MySQL-5.6并安装MySQL-5.1
提问于 2014-07-22 12:12:32
我已经在RHEL5上安装了MySQL5.6.x社区版。一切都很顺利。因为它是我的测试服务器。为了找出执行时间上的差异，我必须再次安装MySQL5.1社区版本。所以，我决定先卸载MySQL5.6。为此，我遵循以下步骤：
1. uninstall MySQL server and client
# sudo yum erase mysql
2. Uninstall mysql libraries
# sudo yum remove mysql-libs
3. clean db cache
# sudo yum clean dbcache
4. find each and every instance of MySQL
# sudo find / -name mysql*;
5. remove each and every instance of MySQL and Even libmysqlclient.so too.
# sudo rm -r /directory path
6. install shared library
# sudo rpm -ivh /u000/mysql_installer/MySQL-shared-community-5.1.73-1.rhel5.x86_64.rpm
Result: successful 100%
6. install shared compat if you face any issue
# sudo rpm -ivh /u000/mysql_installer/MySQL-shared-compat-5.1.73-1.rhel5.x86_64.rpm
Result: successful 100%
7. install mysql server
# sudo rpm -ivh /u000/mysql_installer/MySQL-server-community-5.1.73-1.rhel5.x86_64.rpm但是，我遇到了很多冲突错误，如下所示：

您还没有卸载MySQL-server-5.6.19-1.rhel5.x86_64和MySQL-server，可能还有其他。请不要手动删除包文件，因为这只会使事情更成问题。
I 引用一个类似的答案我写了一段时间 ago：
搜索现在安装的与mysql相关的包：
rpm -qa | grep -i mysql删除像mysql、mysql服务器、mysql客户端、mysql共享、mysql共享-compat、mysql-libs之类的包。yum remove mysql-server etc.您不需要删除mysql库绑定，比如python、php等等，除非它们与前面的一些包有依赖关系。
然后，按照您的做法安装所需的版本。
您遇到问题的原因是，取决于安装源(官方存储库、发行版存储库、第三方，.)包的名称可能略有不同，您可能会陷入某种依赖地狱，在供应商/存储库之间移动时会造成一些麻烦。这也可能有点误导，因为mysql包可能包括别名和转换包。固定和优先次序可以使它更顺畅，但它并不总是微不足道的。
警告:如果您试图重用配置文件和/或数据文件(删除时不会删除这些文件)，请小心，因为在某些情况下，由于二进制格式的更改(除非特别注意)，将等级从5.6降到5.5/5.1可能不兼容。
提示:如果您希望在不同版本之间迁移时具有更大的灵活性，则可以使用自动内容二进制包。它真的很适合测试。您失去了简单的升级和包管理，但您获得了许多控制(例如，降级，在一个错误)。MySQL砂箱也是一个非常好的工具来管理不同版本和拓扑的测试。
