安装perl和DBI-mysql出现的一些问题

安装perl后， 因为想要运行innotop，mytop之类的perl文件。 所以出现了一系列问题：

1. Can't locate Time/HiRes.pm in

原因：perl包没有安装完全。

解决办法：

.pm实际上是Perl的包，只需安装如下软件包即可：

yum install perl-Time-HiRes

2. failed: Can't locate DBD/mysql.pm in

原因1： 可能是perl-DBD-MySQL没安装。

yum install perl-DBD-MySQL

虽然我用yum安装了perl-DBD-MySQL, 但是还是不不成功。 依然是报这个错误。

问题没有解决。

原因2： DBD-mysql没有安装，下载DBD-mysql。

解压：tar xzvf DBD-mysql**.tar.gz
进入该目录：cd DBD-mysql*

下面的要注意了：

perl Makefile.PL --mysql_config=/usr/lib64/mysql/mysql_config

如果不在lib64目录下的话， 请find下它。

接下来是更蛋疼的事情-----make。

make

结果出现了：

在dbdimp.c里面出现了一系列的错误。

我查找了/usr/include， 结果发现没有mysql相关的头文件。 哎， 赶紧装相关的头文件吧。

方法一： 编译mysql源码安装mysql。

请参考
编译安装mysql

方法二： yum 安装mysql-devel (我当然推荐这种方法啦)

yum install mysql-devel

查看/usr/include目录， 有了/usr/include/mysql文件夹。

接下来正常进行：

make
make test
make install

发现问题解决了。
