#mysql:command not found

1、問題描述

　　一、在linux中已經安裝好mysql，經過#ps -ef |ｇrep mysql 能顯示mysql已經啓動，但去進入mysql命令頁面出現以下問題：

1 　　[root@root ~]# mysql u -p
2 -bash: mysql: command not found

 　　查找mysql是否已經啓動

1 [root@root ~]# ps -ef  | grep mysql
2 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.pid
3 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.pid
4 root      1440  1288  0 18:28 pts/1    00:00:00 grep mysql

　　二、查找問題產生緣由：

　　緣由:這是因爲系統默認會查找/usr/bin下的命令，若是這個命令不在這個目錄下，固然會找不到命令，咱們須要作的就是映射一個連接到/usr/bin目錄下，至關於創建一個連接文件。
首先得知道mysql命令或mysqladmin命令的完整路徑，好比mysql的路徑是：/usr/local/mysql/bin/mysql，【此路經是mysql實際安裝路徑】咱們則能夠這樣執行命令　　

1 [root@root bin]# ln -fs /usr/local/mysql/bin/mysql /usr/bin/

　　三、鏈接mysql　　

 1 [root@root bin]# mysql -u -p
