安装MySQL

 安装MySQL和php-mysql

[root@sample ~]# yum -y install mysql-server  
[root@sample ~]# yum -y install php-mysql 

配置MySQL

[root@sample ~]#vim /etc/my.cnf  编辑MySQL的配置文件
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).

  找到

old_passwords=1 

这一行,在这一行的下面添加新的规则,让MySQL的默认编码为UTF-8,添加

default-character-set = utf8 

这一行
然后在配置文件的文尾填加如下语句:
[mysql]

default-character-set = utf8

启动MySQL服务

[root@sample ~]# chkconfig mysqld on

设置MySQL服务随系统启动自启动

[root@sample ~]# chkconfig --list mysqld

确认MySQL自启动

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

   如果2--5为on的状态就OK

[root@sample ~]#/etc/rc.d/init.d/mysqld start

启动MySQL服务

Initializing MySQL database:         [ OK ]
Starting MySQL:              [ OK ]

开放 MySQL 服务远程访问

修改数据库配置:

授权root用户进行远程连接,注意替换 “password” 为 root 用户真正的密码:

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

第二行命令使设置生效,可以马上连接。

PS:Ubuntu系统下则需要:

vim /etc/mysql/my.cnf

找到:

bind-address = 127.0.0.1

改为:

bind-address = 0.0.0.0
#允许任意ip地址访问

也可以指定IP地址。然后重启MySQL:

sudo /etc/init.d/mysqld restart
