今天就跟大家聊聊有关怎么在Linux中修改MySQL数据库数据文件路径,可能很多人都不太了解,为了让大家更加了解,小编给大家总结了以下内容,希望大家根据这篇文章可以有所收获。 步骤: 1、创建目标路径 mkdir -p /home/mysql_data 2、关闭MySQL systemctl stop mysqld 3、复制数据文件 cp -arp /var/lib/mysql /home/mysql_data 4、修改配置文件/etc/my.cnf 将datadir和socket中的原路径修改为目标路径 datadir=/home/mysql_data/mysql socket=/home/mysql_data/mysql/mysql.sock 5、启动MySQL服务 systemctl start mysqld NOTE: 1、报错如下: 2019-12-22T08:32:42.430564Z 0 [ERROR] InnoDB: Operating system error number 13 in a file operation. 2019-12-22T08:32:42.430599Z 0 [ERROR] InnoDB: The error means mysqld does not have the access rights to the directory. 2019-12-22T08:32:42.430616Z 0 [Note] InnoDB: Creating shared tablespace for temporary tables 2019-12-22T08:32:42.430898Z 0 [ERROR] InnoDB: The innodb_temporary data file 'ibtmp1' must be writable 2019-12-22T08:32:42.430923Z 0 [ERROR] InnoDB: The innodb_temporary data file 'ibtmp1' must be writable 2019-12-22T08:32:42.430936Z 0 [ERROR] InnoDB: Could not create the shared innodb_temporary. 2019-12-22T08:32:42.430952Z 0 [ERROR] InnoDB: Plugin initialization aborted with error Generic error 2019-12-22T08:32:43.038973Z 0 [ERROR] InnoDB: Operating system error number 13 in a file operation. 2019-12-22T08:32:43.039021Z 0 [ERROR] InnoDB: The error means mysqld does not have the access rights to the directory. 2019-12-22T08:32:43.039037Z 0 [ERROR] Plugin 'InnoDB' init function returned error. 2019-12-22T08:32:43.039046Z 0 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. 2019-12-22T08:32:43.039056Z 0 [ERROR] Failed to initialize builtin plugins. 2019-12-22T08:32:43.039063Z 0 [ERROR] Aborting 解决: 执行命令: setenforce 1 再重新启动 2、报错如下: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' 解决: 修改配置文件my.cnf,添加或修改如下配置: [client] socket = /home/mysql_data/mysql/mysql.sock 看完上述内容,你们对怎么在Linux中修改MySQL数据库数据文件路径有进一步的了解吗?
