實例講解啟動mysql server失敗的解決方法

啟動mysql server 失敗,查看/var/log/mysqld.err



080329 16:01:29 [ERROR] Cant start server : Bind on unix socket: No such file or directory


080329 16:01:29 [ERROR] Do you already have another mysqld server running on socket: /var/run/mysqld/mysqld.sock ?


080329 16:01:29 [ERROR] Aborting


080329 16:01:29 InnoDB: Starting shutdown…


080329 16:01:30 InnoDB: Shutdown completed; log sequence number 0 4646872


080329 16:01:30 [Note] /usr/sbin/mysqld: Shutdown complete


百思不得其解,後來查看/var/db/pkg/dev-db/mysql-5.0.56/CONTENTS 文件,或者執行equery f mysql(兩種方法非Gentoo Linux 發佈不適用),得知安裝文件中包含/var/run/mysqld,而這個目錄不存在,回憶起之前曾清空過/var/run目錄,一直以為這下面的內容都是動態創建,刪除之後重啟系統即可,看來對mysql 來說還不是這麼回事。



創建此目錄,並chown,問題解決。



# mkdir /var/run/mysqld


# chown mysql:mysql /var/run/mysqld
