redhat 5.5安装mha

安装manager节点依赖包：
shell> yum install perl-DBD-MySQL
shell> yum install perl-Config-Tiny
shell> yum install perl-Log-Dispatch
shell> yum install perl-Parallel-ForkManager

安装perl-Log-Dispatch的时候报错：
# rpm -ivh perl-Log-Dispatch-2.26-1.el5.rf.noarch.rpm
warning: perl-Log-Dispatch-2.26-1.el5.rf.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 6b8d79e6
error: Failed dependencies:
perl(Params::Validate) >= 0.15 is needed by perl-Log-Dispatch-2.26-1.el5.rf.noarch

缺少perl-perl-Params-Validate-*

常用的搜索、下载rpm的网站：
http://apt.sw.be/
http://rpm.pbone.net/

下载perl-Params-Validate-0.95-5.1.x86_64.rpm，安装：

warning: perl-Params-Validate-0.95-5.1.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID d91ca522
error: Failed dependencies:
perl(Attribute::Handlers) >= 0.79 is needed by perl-Params-Validate-0.95-5.1.x86_64

这是因为安装了旧版本的GPG keys造成的，解决办法就是
rpm --import /etc/pki/rpm-gpg/RPM*
加上安装参数，重新安装：
[root@bssnusb04 ~]# rpm -ivh perl-Params-Validate-0.95-5.1.x86_64.rpm --force --nodeps
warning: perl-Params-Validate-0.95-5.1.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID d91ca522
