wan3574489

我是根據(jù)http://ahbydz.com/bbs/thread-2523-1-1.html這個(gè)來進(jìn)行安裝的,   安裝完畢產(chǎn)生
    '無(wú)法連接mysql，請(qǐng)檢查mysql是否已啟動(dòng)及用戶密碼是否設(shè)置正確'錯(cuò)誤  然后發(fā)現(xiàn)mysql沒有被安裝成功, 查看mysql日志,
    '
130308 12:50:17 mysqld_safe Starting mysqld daemon with databases from /www/wdlinux/mysql-5.1.63/var
130308 12:50:17 [ERROR] Fatal error: Can't change to run as user 'mysql' ;  Please check that the user exists!

130308 12:50:17 [ERROR] Aborting

130308 12:50:17 [Note] /www/wdlinux/mysql-5.1.63/libexec/mysqld: Shutdown complete

130308 12:50:17 mysqld_safe mysqld from pid file /www/wdlinux/mysql-5.1.63/var/xxxxxxxxx.pid ended
'

根據(jù)錯(cuò)誤提示,我新建了一個(gè)mysql用戶,然后又產(chǎn)生錯(cuò)誤:
'
130308 13:20:46 mysqld_safe Starting mysqld daemon with databases from /www/wdlinux/mysql-5.1.63/var
^G/www/wdlinux/mysql-5.1.63/libexec/mysqld: Can't find file: './mysql/plugin.frm' (errno: 13)

130308 13:20:46 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.

130308 13:20:46 [ERROR] /www/wdlinux/mysql-5.1.63/libexec/mysqld: Can't create/write to file '/www/wdlinux/mysql-5.1.63/var/xxxx.pid' (Errcode: 13)

130308 13:20:46 [ERROR] Can't start server: can't create PID file: Permission denied

130308 13:20:46 mysqld_safe mysqld from pid file /www/wdlinux/mysql-5.1.63/var/xxxx.pid ended


'
然后根據(jù)錯(cuò)誤提示,更改用戶權(quán)限,新建一個(gè)xxxx.pid文件,好了，mysql啟動(dòng)成功！

重置了mysql的root密碼,然后更改php配置文件,更改mysql連接配置,打開網(wǎng)站顯示錯(cuò)誤:'一條mysql錯(cuò)誤'!


求解決方法？
