我已经在 CENTOS 6.5 上成功安装了 InifiniDB。InfiniDB 是与 MySQL“兼容”的柱状数据库（相同的端口等：我什至设法安装了最新版本的 MySQLWorkbench，并且与 InifiniDB 一起工作很有魅力 - 相信只需处理另一个安装的 MySQL）。

安装没有 MySQL，因为我不需要它:)

我尝试从 RStudio Server 安装 RMySQL，但无法安装：安装程序希望在某处找到 MySQL 的副本，但我没有。

请参阅下面的安装日志。我将 :/usr/local/Calpont/mysql/bin 放在我的 PATH 中，但这没有任何效果。

请考虑到这个灵感来自 InfiniDB 本身：见这里http://infinidb.co/system/files/Calpont%20InfiniDB_Quick%20Start_for%20R.pdf 我猜主要问题，比较错误和 InfiniDB 论文，是他们建议创建以下全局变量：

(From InfiniDB paper) RMySQL must be configured with the correct MySQL directory 
(which comes with InfiniDB) and the developer library directory. 
o Example in Ubuntu or CentOS: 
export MYSQL_INC=”/usr/include/mysql/”
export MYSQL_LIB=”/usr/local/Calpont/mysql/lib/mysql”

但是我在 CENTOS 上的安装在 /usr/include/mysql/ 没有 mysql 文件夹。

有什么建议么？

Configuration error:
  could not find the MySQL installation include and/or library
  directories.  Manually specify the location of the MySQL
  libraries and the header files and re-run R CMD INSTALL.

INSTRUCTIONS:

1. Define and export the 2 shell variables PKG_CPPFLAGS and
   PKG_LIBS to include the directory for header files (*.h)
   and libraries, for example (using Bourne shell syntax):

      export PKG_CPPFLAGS="-I<MySQL-include-dir>"
      export PKG_LIBS="-L<MySQL-lib-dir> -lmysqlclient"

   Re-run the R INSTALL command:

      R CMD INSTALL RMySQL_<version>.tar.gz

2. Alternatively, you may pass the configure arguments
      --with-mysql-dir=<base-dir> (distribution directory)
   or
      --with-mysql-inc=<base-inc> (where MySQL header files reside)
      --with-mysql-lib=<base-lib> (where MySQL libraries reside)
   in the call to R INSTALL --configure-args='...' 

   R CMD INSTALL --configure-args='--with-mysql-dir=DIR' RMySQL_<version>.tar.gz

您确实需要安装 mysql-devel。请参阅 InfiniDB 网站上 R 快速入门指南的第 3 步。它声明如下：

在客户端机器上安装 MySQL 开发人员库。可从http://www.mysql.com和http://dev.mysql.com 获得，或者您可以使用像 apt-get 这样的包安装程序。如果您已经安装了 MySQL 服务器，请确保客户端头文件和库文件包含在安装中。

Ubuntu 中的示例：

sudo apt-get install mysql-client libmysqlclient-dev

CentOS 中的示例

sudo yum install mysql mysql-devel

如果您还有其他问题，请随时在 InfiniDB 论坛中发帖。

我找到了一个解决方案。

首先，我的前提是能够在不添加 MySQL 安装的情况下将 RMySQL 与 InfiniDB 一起使用。

（根据维基百科）“通过 MySQL 接口访问 InfiniDB”。最近一篇关于 R 和 InifiniDB 的 InfiniDB 网站上的论文（“R 统计计算快速入门指南”）列出了在 R 中使用 RMySQL 安装和使用 InfiniDB 的简单说明，没有提及任何先决条件。

我发现这是不正确的。在我的 CENTOS 安装中，我无法编译 RMySQL 包。缺少的 mysql.h 阻止了它。

我找到的解决方案是用 yum 安装 mysql-devel。Yum 还安装了 mysql 客户端程序和共享库作为依赖项。

另一方面，使用 yum 的总安装量为 3MB，我仍然可以说我不需要安装 MySQL 服务器（至少！），因为 RMySQL+InfiniDB 只需要 MySQL 库即可工作。
