背景:
在Linux环境下安装Alfresco,配置数据库连接其它节点的MySQL,当启动alfresco服务的时候日志报错“HOST **** is not allowed to connect to this MySQL server”,这是因为你的MySQL数据库不允许帐号从远程登陆,只能在localhost。
解决方法:
1。 修改user表字段值。只要在localhost的那台电脑,登入mysql后,更改 "mysql" 数据库里的 "user" 表里的 "host" 字段,把值从"localhost"改称"%",如下图所示:
也可以执行下面命令修改user表中的host字段值:
1)登录
mysql -u root -p
2)进入mysql数据库
mysql>use mysql;
3)更新字段值
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;
注意:改完表要重启MYSQL服务
2. 可以直接授权,让用户Alfresco可以从任何主机连接到mysql服务器
GRANT ALL PRIVILEGES ON *.* TO 'Alfresco'@'%' IDENTIFIED BY 'Alfresco' WITH GRANT OPTION;
如果想允许用户Alfresco从ip为192.168.67.129的主机连接到mysql服务器,并使用Alfresco作为密码
GRANT ALL PRIVILEGES ON *.* TO 'Alfresco'@'192.168.0.105' IDENTIFIED BY 'Alfresco' WITH GRANT OPTION;
其实上述解决方法就是在MySQL数据库的设置,熟悉MySQL,这些问题很容易处理。

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.
