        mysql移動數據存放目錄及問題

        2013-12-29 19:24:47 本站原創 佚名 【字體: {SQL_我要評論()}

        我計劃更換數據庫的存放目錄,下面是我的操作步驟

        1:首先創建新的數據存放路徑并授予權限

        #socket =/mnt/resource/mysqldate/mysql.sock
        socket =/mnt/mntsdc2formysql/mysqldata/mysql.sock

        5:啟動mysql

        [root@pacteralinux mysqldata]#

        至此,mysql數據存放路徑移動完成!

        其中,有幾個小疑問

        • 我看到有的博文里面說需要修改啟動腳本/etc/init.d/mysqld的datadir參數,我看了一下該腳本,如下

        1
        2
        3
        4
        5
        6
        7
        8
        9
        10
        11
        12
        13
        14
        15
        16
        17
        18
        19
        20
        21
        22
        basedir=
        datadir=
        # Default value, in seconds, afterwhich the script should timeout waiting
        # for server start.
        # Value here is overriden by value in my.cnf.
        # 0 means don't wait at all
        # Negative numbers mean to wait indefinitely
        service_startup_timeout=900
        # Lock directory for RedHat / SuSE.
        lockdir='/var/lock/subsys'
        lock_file_path="$lockdir/mysql"
        # The following variables are only set for letting mysql.server find things.
        # Set some defaults
        mysqld_pid_file_path=
        if test -z "$basedir"
        then
          basedir=/usr/local/mysql
          bindir=/usr/local/mysql/bin
          if test -z "$datadir"
          then
            datadir=/mnt/resource/mysqldate
          fi

        我看到datadir還是之前的那個路徑,不知道要不要改!

        • 還有,我看到有人說新路徑要設置為777權限,設置為755權限報錯,但是我的卻沒有報錯

         

        在這個過程中出現的問題

        問題描述:當我在mysql-front工具上連接mysql數據庫時沒有問題,但是當我在命令行連接時報錯:

        1
        2
        3
        [root@pacteralinux weixindemo]# mysql -u root -p
        Enter password:
        ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/mnt/resource/mysqldate/mysql.sock' (2)

        很奇怪,這個路徑不是改過嘛,看代碼:

        1
        2
        #socket =/mnt/resource/mysqldate/mysql.sock
        socket =/mnt/mntsdc2formysql/mysqldata/mysql.sock

        但是為什么還是報以前的路徑錯誤,以為問題出在啟動腳本上/etc/init.d/mysqld ,但是看了下,啟動腳本里面沒有設置socket相關項了!沒辦法,還是把/etc/init.d/mysqld的datedir改為現在的安裝路徑

        1
        2
        3
        [root@pacteralinux ~]# vi /etc/init.d/mysqld
        basedir=/mnt/resource/mysqldate
        datadir=

        重啟還是報同樣的錯,沒辦法,看下錯誤日志吧:
