Centos 配置系列之 mysql

一、安裝 MySQL

首先來進行 MySQL 的安裝。打開超級終端，輸入：

<span class="sh_symbol">[</span>root@localhost <span class="sh_symbol">~]</span># yum install mysql mysql<span class="sh_symbol">-</span>server

安裝完畢，讓 MySQL 能夠隨系統自動啓動：

<span class="sh_symbol">[</span>root@localhost <span class="sh_symbol">~]</span># chkconfig <span class="sh_symbol">--</span>levels <span class="sh_number">235</span> mysqld on
<span class="sh_symbol">[</span>root@localhost <span class="sh_symbol">~]</span># <span class="sh_regexp">/etc/i</span>nit<span class="sh_symbol">.</span><span class="sh_normal">d</span><span class="sh_symbol">/</span>mysqld start

設置 MySQL 數據 root 賬戶的密碼：

<span class="sh_symbol">[</span>root@localhost <span class="sh_symbol">~]</span># mysql_secure_installation

當出現如下提示時候直接按回車：

Enter current password <span class="sh_keyword">for</span> root

出現如下再次回車：

Set root password<span class="sh_symbol">?</span> <span class="sh_symbol">[</span><span class="sh_normal">Y</span><span class="sh_symbol">/</span>n<span class="sh_symbol">]</span>

出現如下提示輸入你需要設置的密碼，回車後在輸入一次確認：

New password<span class="sh_symbol">:</span>

接下來還會有四個確認，分別是：

Remove anonymous users<span class="sh_symbol">?</span> <span class="sh_symbol">[</span><span class="sh_normal">Y</span><span class="sh_symbol">/</span>n<span class="sh_symbol">]</span>
Disallow root login remotely<span class="sh_symbol">?</span> <span class="sh_symbol">[</span><span class="sh_normal">Y</span><span class="sh_symbol">/</span>n<span class="sh_symbol">]</span>
Remove test database and access to it<span class="sh_symbol">?</span> <span class="sh_symbol">[</span><span class="sh_normal">Y</span><span class="sh_symbol">/</span>n<span class="sh_symbol">]</span>
Reload privilege tables now<span class="sh_symbol">?</span> <span class="sh_symbol">[</span><span class="sh_normal">Y</span><span class="sh_symbol">/</span>n<span class="sh_symbol">]</span>

直接回車即可。

二、創建新用戶

//登錄MYSQL
@>mysql -u root -p
@>密碼
//創建用戶
mysql> insert into mysql.user(Host,User,Password) values("localhost","phplamp",password("1234"));
//刷新系統權限表
mysql>flush privileges;

這樣就創建了一個名爲：phplamp  密碼爲：1234  的用戶。

三、授予權限
>grant all privileges on phplampDB.* to phplamp@localhost identified by '1234';
//刷新系統權限表
mysql>flush privileges;
mysql>其它操作

/*
如果想指定部分權限給一用戶，可以這樣來寫:
mysql>grant select,update on phplampDB.* to phplamp@localhost identified by '1234';
//刷新系統權限表。
mysql>flush privileges;
*/
