centos8安裝mysql8.0出現的問題
[root@hecs-70178 mysql8.0.11] ./bin/mysqld --user=mysql --basedir=/usr/local/mysql/mysql8.0.11/ --datadir=/usr/local/mysql/mysql8.0.11/data/ --initialize
./bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
在執行初始化的時候發現了錯誤libaio包還沒安裝
這個時候就去安裝libaio包
yum install libaio
發現又有報錯
Errors during downloading metadata for repository 'AppStream':
- Status code: 404 for https://repo.huaweicloud.com/centos/8/AppStream/x86_64/os/repodata/repomd.xml (IP: 59.39.0.154)
Error: Failed to download metadata for repo 'AppStream': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
這里出現的問題是centos8 yum源的配置問題，因為國內被墻了就會導致404
這個時候可以看這個大哥的文章

只要更換了yum源以后再次yum就可以裝了libaio包了
安裝了libaiio以后
