安装mysql 5.7.19 rpm包报错：/usr/bin/perl is needed by mysql-community-server-5.7.19-1.el7.x86_64

一、问题描述

从mysql官网下载mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar，然后解压安装。安装顺序如下

rpm -ivh mysql-community-common-5.7.19-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.19-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-compat-5.7.19-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.19-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm

前四个都没有问题，但是安装第五个mysql-community-server-5.7.19-1.el7.x86_64.rpm时报错

rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm 
报错：

        perl(strict) is needed by mysql-community-server-5.7.19-1.el7.x86_64

二、问题原因

很简单，如错误信息显示，缺少net-tools.x86_64，libaio.x86_64，perl.x86_64三个依赖，使用yum安装即可。

三、问题解决

1.查找依赖对应包

yum search perl
yum search libaio 
yum search net-tools

2.yum安装对应包

yum -y install perl.x86_64
yum install -y libaio.x86_64
yum -y install net-tools.x86_64

总之，仔细看报错信息！
