摘要：Mysql出现问题：error while loading shared libraries: libaio解决方案。

本文分享自华为云社区《Mysql出现问题：error while loading shared libraries: libaio解决方案》，作者：小虚竹。

问题

初始化数据库时

mysqld --initialize --user mysql

报错：

mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

执行这行命令报错了，原因是：新的服务器环境，上面很多依赖都没有，所以安装软件的时候遇到一大堆小问题，解决它很简单，它缺少啥就安装啥。

解决方案

yum install -y libaio.so.1

又报错了：

Errors during downloading metadata for repository ‘epel’:
Status code: 404 for http://archives.fedoraproject.org/pub/archive/epel/8/Everything/x86_64/repodata/repomd.xml (IP: **)
Error: Failed to download metadata for repo ‘epel’: Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

原因是：第三方的镜像站中均已移除CentOS 8的源，Centos 8版本已停止更新相应依赖导致的，下载新的yum源即可搞定。

解决方案：备份之前的repo文件，命令：

mv /etc/yum.repos.d /etc/yum.repos.d.bak

创建源文件目录，命令：

mkdir -p /etc/yum.repos.d

下载新的yum源

curl https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo > /etc/yum.repos.d/Centos-vault-8.5.2111.repo
curl https://mirrors.aliyun.com/repo/epel-archive-8.repo > /etc/yum.repos.d/epel-archive-8.repo

如图所示操作：

再下载依赖：

yum install -y libaio.so.1

再安装

yum install -y libaio

提示成功后，初始化数据库：

mysqld --initialize --user mysql
