#mysql:command not found

一、問題描述

　　1、在linux中已經安裝好mysql，通過#ps -ef |ｇrep mysql 能顯示mysql已經啟動，但去進入mysql命令頁面出現如下問題：

1 　　[[email protected] ~]# mysql u -p2 -bash: mysql: command not found

 　　尋找mysql是否已經啟動

1 [[email protected] ~]# ps -ef  | grep mysql2 root      1172     1  0 18:28 ?        00:00:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/service/mysql --pid-file=/service/mysql/root.pid3 mysql     1285  1172  9 18:28 ?        00:00:01 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/service/mysql --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/service/mysql/root.err --pid-file=/service/mysql/root.pid4 root      1440  1288  0 18:28 pts/1    00:00:00 grep mysql

　　2、尋找問題產生原因：

　　原因:這是由於系統預設會尋找/usr/bin下的命令，如果這個命令不在這個目錄下，當然會找不到命令，我們需要做的就是映射一個連結到/usr/bin目錄下，相當於建立一個連結檔案。
首先得知道mysql命令或mysqladmin命令的完整路徑，比如mysql的路徑是：/usr/local/mysql/bin/mysql，【此路經是mysql實際安裝路徑】我們則可以這樣執行命令　　

1 [[email protected] bin]# ln -fs /usr/local/mysql/bin/mysql /usr/bin/

　　3、串連mysql
