查看配置文件：http://www.cndba.cn/cndba/leo1990/article/2668

[root@www.cndba.cn support-files]# more /etc/my.cnf |grep -v ^#
[mysqld]
port            = 3307
socket          = /tmp/mysql.sock
basedir         = /usr/local/mysql
datadir         = /data1/mysql/data

查了很长时间发现，创建数据文件mysql_install_db 的时候指定datadir目录是/data/mysql,而/etc/my.cnf 缺省的路径：/data1/mysql/datahttp://www.cndba.cn/cndba/leo1990/article/2668http://www.cndba.cn/cndba/leo1990/article/2668

[root@www.cndba.cn mysql]# scripts/mysql_install_db --user=mysql --datadir=/data/mysql

解决方法：

将配置人家/etc/my.cnf中datadir 目录改为：/data/mysql 即可
[root@www.cndba.cn support-files]# service mysql start
Starting MariaDB.180227 01:56:37 mysqld_safe Logging to '/data/mysql/log/error.log'.
180227 01:56:37 mysqld_safe Starting mysqld daemon with databases from /data/mysql
.                                                          [  OK  ]
