通过以下命令，完成对
mysql数据库的初始化和相关配置[root@Centos mysql]# mysqld --initialize [root@Centos mysql]# chown mysql:mysql /usr/local/mysql -R [root@Centos mysql]# systemctl start mysqld.service [root@Centos mysql]# systemctl enable mysqld如果执行
mysqld --initialize的时候报错,就需要安装libaio[root@Centos mysql]# mysqld --initialize mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory解决方式：
[root@Centos mysql]# yum install -y libaio如果提示日志提示：
[ERROR] [MY-012271] [InnoDB] The innodb_system data file 'ibdata1' must be writable
解决方式：设置权限
[root@Centos mysql]# find / -name ibdata1 /var/lib/mysql/ibdata1 [root@Centos mysql]# chmod -R 777 /var/lib/mysql 通过
cat /var/log/mysqld.log | grep password命令查看数据库的密码
