四台机器的系统情况：
OS:CentOS7.3
MySQL:5.7.21
MHA:0.58
网卡名：ens3
master slave安装mha4mysql-node-0.58
# yum install perl-CPAN perl-DBD-MySQL perl-Config-Tiny perl-Email-Date-Format perl-Log-Dispatch perl-Mail-Sender perl-Mail-Sendmail perl-MIME-Lite perl-MIME-Types perl-Parallel-ForkManager perl-Params-Validate perl-Time-HiRes # cd /tmp/mha # wget https://github.com/yoshinorim/mha4mysql-node/releases/download/v0.58/mha4mysql-node-0.58.tar.gz # tar -zxvf mha4mysql-node-0.58.tar.gz # cd mha4mysql-node-0.58 # perl Makefile.PL # make # make install
manger节点安装 mha4mysql-manager-0.58,在安装 mha manager 之前，必须要先安装 mha node，参照上面完成安装后，再进行下面的操作。
# cd /tmp/mha # wget https://github.com/yoshinorim/mha4mysql-manager/releases/download/v0.58/mha4mysql-manager-0.58.tar.gz # tar -zxvf mha4mysql-manager-0.58.tar.gz # cd mha4mysql-manager-0.58 # perl Makefile.PL # make # make install
