MySQL 安装与使用（一）

操作系统：CentOS release 5.10 （Final）

文件准备：

MySQL-server-community-5.1.73-1.rhel5.i386.rpm

MySQL-client-community-5.1.73-1.rhel5.i386.rpm

一、安装MySQL

rpm包安装：

切换到包所在目录，执行：

rpm -i MySQL-server-community-5.1.73-1.rhel5.i386.rpm

rpm -i MySQL-client-community-5.1.73-1.rhel5.i386.rpm

完成后MySQL的顶级安装目录为/usr。注意，如果只是安装了MySQL-server的话，在这些路径中像mysql、mysqladmin等是没有的，也是无法使用的。

二、安装完成后的相关配置

1.运行mysql_install_db 程序设置含有确定如何让用户连接服务器的权限的初始MySQL授权表。

/usr/bin/mysql_install_db --user=root

mysql_install_db脚本创建数据目录、拥有所有数据库权限的mysql数据库和可以用来测试MySQL的test数据库。脚本为root账户和匿名用户账户创建授权表条目。

2.启动数据库。

/usr/bin/mysqld_safe --user=mysql &

3.配置数据库

为数据库设定一个密码(初始为空)：

/usr/bin/mysqladmin -u root password 'new-password'

卸掉test数据库：

/usr/bin/mysqladmin -u root drop test

以上两个操作可以由mysql_secure_installation脚本代替：

/usr/bin/mysql_secure_installation

其功能包括：

Change the root password?

Remove anonymous users?

Disallow root login remotely?

Remove test database and access to it?

Reload privilege tables now?

4.关闭数据库

/etc/init.d/mysql stop

或

mysqadmin shutdown -uroot -p

5.自动启动数据库

如果④中/etc/init.d/mysql存在或有效，则数据库很可能是已经自动启动的，用以下方法确认：

[root@localhost ~]# chkconfig --list | grep mysql

mysql           0:off   1:off   2:on    3:on    4:on    5:on    6:off

如果能够列出mysql的启动状态，而且至少3和4为on，则说明mysql能够自动启动。如不能，接着配置：

cd /usr/share/mysql/

cp mysql.server /etc/init.d/mysql

chmod +x /etc/init.d/mysql

chkconfig --addMySQL

chkconfig --level 345MySQL on

在配置自动启动数据库可能会遇到的问题：

当执行

/etc/init.d/mysql

时出现

Starting MySQL.Manager of pid-file quit without updating file [Failed]

查询日志：

cat /var/lib/mysql/localhost.localdomain.err

有错误

/usr/sbin/mysqld: File './mysql-bin.index' not found (Errcode: 13)
140507 21:38:01 [ERROR] Aborting

而这时，执行

/etc/init.d/mysql --user=root

带上参数user是没问题的（--user=root或--user=mysql）

解决办法：

chgrp -R mysql /var/lib/mysql/

chown -R mysql /var/lib/mysql/

/var/lib/mysql/ 是mysql-bin.index所在的文件夹。

6.匿名账户

①为匿名用户指定密码，可以用SET PASSWORD或UPDATE。在两种情况中，一定要使用PASSWORD()函数为密

码加密。

使用SET PASSWORD方法:

shell> mysql -u root

mysql> SET PASSWORD FOR ''@'localhost' = PASSWORD('newpwd');

mysql> SET PASSWORD FOR ''@'host_name' = PASSWORD('newpwd');

使用UPDATE直接修改用户表：

shell> mysql -u root

mysql> UPDATE mysql.user SET Password = PASSWORD('newpwd')

    ->     WHERE User = '';

mysql> FLUSH PRIVILEGES;

在user表中直接使用UPDATE更新密码后，必须让服务器用FLUSH PRIVILEGES重新读授权表。否则，重新启动服务器

前，不会使用更改。

②删除匿名账户

shell> mysql -u root

mysql> DELETE FROM mysql.user WHERE User = '';

mysql> FLUSH PRIVILEGES;

7.为root账户指定密码

①使用SET PASSWORD语句：

shell> mysql -u root

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpwd');

mysql> SET PASSWORD FOR 'root'@'host_name' = PASSWORD('newpwd');

②使用mysqladmin命令行客户端程序：

shell> mysqladmin -u root password "newpwd"

shell> mysqladmin -u root -h host_name password "newpwd"

③使用UPDATE语句：

shell> mysql -u root

mysql> UPDATE mysql.user SET Password = PASSWORD('newpwd')

    ->     WHERE User = 'root';

mysql> FLUSH PRIVILEGES;

6.远程连接

①MySQL出于安全因素考虑，默认配置只允许本地登录，打开MySQL配置文件 /etc/mysql/my.cnf，找到 bind-address = 127.0.0.1 修改为 bind-address = 0.0.0.0；

②添加一个远程用户，grant all on *.* to 'userRemote'@'192.168.1.111' identified by '123456' with grant option;

grant all on *.* to 'userRemote'@'192.168.1.111' identified by '' with grant option

这样userRemote就可以从地址192.168.1.111来登录MySQL，如果想不限IP，可以将IP地址设为%，这样这个用户从任意地址都可以访问。

③打开对应防火墙(临时)，iptables -I INPUT 2 -p tcp --dport 3306 -j ACCEPT。

iptables -I INPUT  -p tcp --dport  -j ACCEPT
