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.
