mysql_install_db --defaults-file=/etc/my.cnf --user=mysql

mysql_install_db --defaults-file=/etc/my.cnf --user=mysql

到底懂不懂系统

mysql_install_db --defaults-file=/etc/my.cnf --user=mysql

使用该命令初始化必须保证my.cnf中的目录创建

还要配置属主
chown -R mysql.mysql /data/mysql

chown -R mysql.mysql /data/mysql_backup

初始化好， mysql -uroot -p   应该无需密码
