一、
root@localhost ~]# /usr/local/mysql/mysqld
-bash: /usr/local/mysql/mysqld: 沒有那個文件或目錄
這個就是命令沒找到了
二、
[root@localhost ~]# /usr/local/mysql/bin/mysqld
mysqld: Can't change dir to '/var/lib/mysql/' (Errcode: 2 - No such file or directory)
這個'/var/lib/mysql/'目錄不存在。你可以手動建立，然后再次啟動mysqld。如提示權限問題可以使用sudo

經過兩天的安裝終于完成了，首先我試過這種cmake編譯安裝，編譯時間太長高達幾十分鐘，最后內存直接崩掉（我是筆記本上的虛擬機資源很少）出現很多問題，各種包的安裝還有包的版本兼容問題，最后放棄這個種安裝方式，選用了不用編譯安裝的包就是二進制的包，安裝過程簡單下載解壓后直接可以配置具體流程這個網址http://www.jb51.net/article/87160.htm?pc???我解決了 摸摸噠！
