今天在 Linux 系統上移動 MySQL 的數據庫目錄
配置如下:
/etc/my.cnf
[mysqld]
datadir=/home/mysql
socket=/var/lib/mysql/mysql.sock
更改完配置文件重啟MYSQL的時候出現的以下問題
110222 11:15:07 mysqld_safe Starting mysqld daemon with databases from /home/mysql
110222 11:15:07 [Warning] Can't create test file /home/mysql/localhost.lower-test
110222 11:15:07 [Warning] Can't create test file /home/mysql/localhost.lower-test
/usr/libexec/mysqld: Can't find file: './mysql/plugin.frm' (errno: 13)
110222 11:15:07 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.
110222 11:15:07 InnoDB: Operating system error number 13 in a file operation.
InnoDB: The error means mysqld does not have the access rights to
InnoDB: the directory.
InnoDB: File name ./ibdata1
InnoDB: File operation call: 'open'.
InnoDB: Cannot continue operation.
110222 11:15:07 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended
當初以為只是文件或文件夾權限問題,把所有對應的目錄和文件的權限改成讀寫狀態...還是沒用...
在網上找了一會兒,找到解決方法了~
解決方法如下:
#在終端中先輸入下面這一行
chown -R mysql:mysql /home/data/mysql
#在輸入下面的一行就OK了
chcon -R -t mysqld_db_t /home/mysql
#重啟下MYSQL試試~
/etc/init.d/mysqld restart
