离线安装

安装环境redhat7.4+MHA0.58+MySQL5.7.30

1、下载MHA Node and MHA Manager安装包

https://github.com/yoshinorim

2、配置SSH互信

3、安装 MHA Node

3.1安装目标：

在master、slave、management server节点都需要安装

3.2 在 RHEL/CentOS 操作系统下, 安装如下(两种方式，任选其一)

3.2.1  rpm包安装(https://pkgs.org/)

## If you have not installed DBD::mysql, install it like below, or install from source.

# yum install perl-DBD-MySQL

## Get MHA Node rpm package from "Downloads" section.

 yum -y localinstall mha4mysql-node-0.58-0.el7.centos.noarch.rpm

4、安装 MHA Manager

在master节点安装即可

4.1需要提前安装如下：

MHA Node package

DBD::mysql

Config::Tiny

Log::Dispatch

Parallel::ForkManager

Time::HiRes (included from Perl v5.7.3)

4.2 在 RHEL/CentOS 操作系统下, 安装如下(两种方式，任选其一)

4.2.1 rpm包安装

## Install dependent Perl modules

 yum install perl-DBD-MySQL

 yum install perl-Config-Tiny

 yum install perl-Log-Dispatch

 yum install perl-Parallel-ForkManager

## Install MHA Node, since MHA Manager uses some modules provided by MHA Node.

rpm -ivh mha4mysql-node-X.Y-0.noarch.rpm

## Finally you can install MHA Manager

 rpm -ivh mha4mysql-manager-X.Y-0.noarch.rpm
