今天發現原先虛擬機器的centos系統下的資料庫mysql 竟然一直啟動不起來  檢查啦好久實在是不知道什麼原因  配置檔案也修改過啦。。還是搞不定  後來想想 算了 反正也沒什麼資料  重新編譯安裝下吧。。。    

      按照之前慣例還是選擇使用原始碼編輯安裝 可是等安裝完後要進入資料庫的時候竟然提示說找不到 libmysqlclient.so.15這個檔案  應該是一個庫檔案吧。。。如下提示：

[[email protected] mysql]# bin/mysql -u root -p

bin/mysql: error while loading shared libraries: libmysqlclient.so.15: cannot open shared object   file: No such file or directory

       可是使用find命令查找了下在資料庫安裝目錄下是有libmysqlclient.so.15.0.0及libmysqlclient.so.15這兩個檔案的啊 

[[email protected] mysql]# find . -name libmysqlclient.so.15                           
./lib/mysql/libmysqlclient.so.15                                                                  

[[email protected] mysql]# find . -name libmysqlclient.so.15.0.0                     
./lib/mysql/libmysqlclient.so.15.0.0                                                            

       折騰了會  想想可能是由於系統庫 /usr/lib/關聯起來的原因吧  故覺得試試做了個連結操作

[[email protected] mysql]#sudo ln -s /usr/local/mysql/lib/mysql/libmysqlclient.so.15 /usr/lib/libmysqlclient.so.15                                                                                                         

       還好終於搞定啦。。。但是為什麼會這樣呢 之前貌似都遇到過。。。 

[[email protected] mysql]# bin/mysql -u root -p
