向mysql配置文件my.cnf中添加免除授权
[root@localhost ~]# vim /etc/my.cnf
skip-grant-tables添加后报错缺少东西那就去下
root@localhost mysql]# mysql
mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory
[root@localhost mysql]# dnf -y install libncurses.so.5*
上次元数据过期检查：1:01:05 前，执行于 2022年07月26日 星期二 18时49分17秒。
依赖关系解决。
已安装:ncurses-compat-libs-6.1-9.20180224.el8.x86_64 完毕！
再次登录
