MHA安装遇到的问题解决

MHA依赖了很多的包，如果某个包未安装在运行时都会报错，比如我就遇到如下各种的报错，对perl也不熟，蛋疼的很，记下来帮助其他朋友少走弯路

需要安装的包

yum install -y perl-DBD-MySQL perl-Config-Tiny perl-Log-Dispatch perl-Parallel-ForkManager perl-YAML-Tiny perl-PAR-Dist perl-Module-ScanDeps perl-Module-CoreList perl-Module-Build perl-CPAN perl-CPANPLUS perl-File-Remove perl-Module-Install

yum install perl-DBD-MySQL perl-Config-Tiny perl-Log-Dispatch perl-Parallel-ForkManager perl-Time-HiRes -y

上面是网上见到最多的，但是并不是所有的都在你的yum源中，缺少的也没关系

在执行perl Makefile.PL时会检查都有哪些包安装了，哪些没安装，仔细看一下log如下

include /u01/zjk/mha4mysql-manager-master/inc/Module/Install.pm
include inc/Module/Install/Metadata.pm
include inc/Module/Install/Base.pm
include inc/Module/Install/Scripts.pm
include inc/Module/Install/Makefile.pm
include inc/Module/Install/AutoInstall.pm
include inc/Module/Install/Include.pm
include inc/Module/AutoInstall.pm

在执行make时还会安装一些没有的包，但是有些依然报错，因为yum源上根本就没有，报错也是应该的

*** Installing dependencies...

*** Installing MHA::NodeConst...
*** Could not find a version 0 or above for MHA::NodeConst; skipping.
*** Module::AutoInstall installation finished.

接下来就是运行可执行程序时，因为上面有些包没安装就各种报错了

本错误的解决是 sudo cpanm Socket 从日志看是socket模块出了问题，要么太老要么没装

下载安装DBD::MySQL包安装就好了 http://search.cpan.org/CPAN/authors/id/C/CA/CAPTTOFU/DBD-mysql-4.038.tar.gz

解决：

上面我之所以报了这么多的错，是因为没遇到报错我就下载对应的包，手动安装在机器上，这样无脑的试下去，最后发现实在太多了，最后发现了下面这么个神奇，号称perl最好的安装包工具cpanm, 接下来需要安装这个工具，每次安装包时会报响应依赖也安装了，比较方便
sudo wget http://xrl.us/cpanm -O /usr/bin/cpanm; chmod +x /usr/bin/cpanm
安装好cpanm后就可以用他直接进行安装包了
sudo cpanm Module::Runtime 会把相应依赖一起装了的
