CentOS系统中安装MySQL和开启MySQL远程访问的方法_MySQL
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
