HomeDatabaseMysql TutorialUbuntu下MySQL的安装及远程连接配置等配置

Ubuntu下MySQL的安装,在Ubuntu命令行下输入 sudo apt-get install mysql-server 即可安装mysql服务,默认在安装mysql-server时,

一、Ubuntu下MySQL的安装

在Ubuntu命令行下输入 sudo apt-get install mysql-server 即可安装mysql服务,,默认在安装mysql-server时,会自动安装好mysql-client。

同时安装好的mysql配置文件位置:/etc/mysql/my.cnf

启动mysql的快捷图标为:/etc/init.d/mysql

二、编码问题的解决

查看当前MYSQL字符集[在mysql命令行模式下执行]:show variables like 'character%';

更改编码:sudo vim /etc/mysql/my.cnf

找到[client] 添加如下两句:

//默认字符集为utf8

default-character-set=utf8

找到[mysqld] 添加添加如下四句:(注意每一行的前后都不能有空格)

//默认字符集为utf8

default-character-set=utf8

//设定连接mysql数据库时使用utf8编码,以让mysql数据库为utf8运行

init_connect='SET NAMES utf8'

最后切换到vim的末行模式下执行wq退出vim编辑器.

停止数据库服务:sudo /etc/init.d/mysql stop

重新启动:         s udo /etc/init.d/mysql start

进入数据库:      mysql -uroot -p(你的密码)

查看编码:         show variables like '% character %';

此时应该就全是 utf8编码了。

三、 MySQL服务 加入开机自启动

加入开机自启动:        sudo update-rc.d mysql defaults

从开机自启动中移出:    sudo update-rc.d -f mysql remove

四、远程连接ubuntu下MySQL

vim /etc/mysql/my.cnf找到

bind-address = 127.0.0.1

这行,注释掉(如下)

#bind-address = 127.0.0.1

或者改为

bind-address = 0.0.0.0

允许任意IP访问,或者自己指定一个IP地址。

然后重启 MySQL

sudo /etc/init.d/mysql restart

授权用户能进行远程连接

grant all privileges on *.* to root@"%" identified by "password" with grant option;

flush privileges;

第一行命令解释如下,*.*:第一个*代表数据库名;第二个*代表表名。这里的意思是所有数据库里的所有表都授权给用户。root:授予root账号。“%”:表示授权的用户IP可以指定,这里代表任意的IP地址都能访问MySQL数据库。“password”:分配账号对应的密码,这里密码自己替换成你的mysql root帐号密码。

第二行命令是刷新权限信息,也即是让我们所作的设置马上生效。

此时再远程连接ubuntu下的MySQL应该能够连接上了。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
