MHA-MySQL高可用架构安装过程中遇到的错误以及解决方法

错误1：安装perl-DBD-MySQL的过程中遇到了一个报错，提示缺少libmysqlclient.so.18，缺少一个MySQL依赖的组件。

Error: Package: perl-DBD-MySQL-4.023-6.el7.x86_64 (base)
           Requires: libmysqlclient.so.18()(64bit)
Error: Package: perl-DBD-MySQL-4.023-6.el7.x86_64 (base)
           Requires: libmysqlclient.so.18(libmysqlclient_18)(64bit)

解决：

wget https://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql-community-libs-compat-5.7.31-1.el7.x86_64.rpm && rpm -ivh mysql-community-libs-compat-5.7.31-1.el7.x86_64.rpm
yum install perl-DBD-MySQL -y

错误2：安装manager时执行perl Makefile.PL时，出现

Warning: prerequisite Parallel::ForkManager 0 not found.

原因是cpanm模块未安装

wget https://raw.githubusercontent.com/miyagawa/cpanminus/master/cpanm
cp /root/cpanm /usr/bin/cpanm
 chmod +x /usr/bin/cpanm
 cpanm Parallel::ForkManager #下载缺失的模块

之后进行编译安装就可成功执行

[root@manager mha4mysql-node-0.57]# perl Makefile.PL
