   cd /usr/local
   mkdir mysql

4. 在/usr/local/mysql目錄下使用rz -be命令上傳mysql-8.0.15-1.el7.x86_64.rpm-bundle.tar

5. tar -xvf mysql-8.0.15-1.el7.x86_64.rpm-bundle.tar
   得到文件如圖：

6. rpm -qa | grep mariadb 命令查看 mariadb 的安裝包

7. rpm -e mariadb-libs-5.5.60-1.el7_5.x86_64 --nodeps 卸載mariadb

8. 再次執行6查看

9. rpm -ivh mysql-community-common-8.0.15-1.el7.x86_64.rpm --nodeps --force 命令安裝 common

12. 初始化
    mysqld --initialize;
    [root@1234 mysql]# mysqld --initialize;
    mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
    yum install -y libaio安裝依賴

    mysqld --initialize;
    chown mysql:mysql /var/lib/mysql -R;
    systemctl start mysqld;

13. cat /var/log/mysqld.log | grep password查看密碼
