mysql利用phpmyadmin实现数据库同步更新
以前我们设置数据同步更新需要两台mysql数据库实现主从配置了,下面我来介绍高版本的phpmyadmin就可以快速实现这个功能了,下面我以图文给大家介绍。
台作为从服务器来实现的。在这里我把我做的过程共享一
下,有不对的地方,往各网友指出.
系统:centos linux服务器一台 IP:192.168.0.8 windows2003服
务器一台IP:192.168.0.9
软件:centos linux 服务器安装一台mysql-server5.0 windows2003
安装一个叫Apmserv软件自带一个mysql5.1,phpmyadmin(图形
管理MYSQL数据库)
一,先在主服务建立一个用户,用来同步数据所用,我这里采
用一个图型管理MYSQL数据库软件来建立(phpmyadmin)
在这里注意一点:这个用户管理权限一定要有replicaiion
slave 既是复制权限:
二,我用在从服务器windows2003用刚建的用户admin是否可以
连接到linux(主服器)Apmserv用法我在这里不作详细说明。
在从服务器中运行:mysql -h 192.168.0.8 -u admin -p 然后输入密码
(注意:因为在mysql这个命定在windos系统下是没有的,所以要加一个环境变量)
三,配置主服务器配置文件:vim /etc/my.cnf
server-id=1
log-bin
这二行是新加的
重启mysql
mysql -u root -p
show master status;
(这样表明主服务器配置成功)
四,从服务器配置文件也是my.cnf
server-id=2 从服务器ID号
master-host 主服务器地址
master-port 端口号
master-user 复制需要的用户名
master-password 复制需要的用户名所对应密码
replicate-do-db 所需要复制的数据库
然后重启数据库
mysql>show slave statusG;
主从服务器分别新建一个test1数据库,在主服务器数据插入数 据从服务器可以马上同步的到. * 主服务器IP地址改变时,从服务器。要实现同步只修改/etc/my.cnf是没有用的。需要用到以下命令:
stop slave; reset slave; change master to MASTER_HOST='master_ip', -> MASTER_USER='replication_user_name', -> MASTER_PASSWORD='replication_password', -> MASTER_LOG_FILE='recorded_log_file_name', -> MASTER_LOG_POS=recorded_log_position;
start slave; |
替换其中的master_ip,master_user,master_password为master ip地址,具有复制权限的用户,密码
把recorded_log_file_name替换为上面记录的file,recorded_log_position为上面记录的position

The primary key of a table is one or more columns that uniquely identify each record in the table. Here are the steps to set a primary key: Log in to phpMyAdmin. Select database and table. Check the column you want to use as the primary key. Click "Save Changes". Primary keys provide data integrity, lookup speed, and relationship modeling benefits.

Adding a foreign key in phpMyAdmin can be achieved by following these steps: Select the parent table that contains the foreign key. Edit the parent table structure and add new columns in "Columns". Enable foreign key constraints and select the referencing table and key. Set update/delete operations. save Changes.

The WordPress database is housed in a MySQL database that stores all website data and can be accessed through your hosting provider’s dashboard, FTP, or phpMyAdmin. The database name is related to the website URL or username, and access requires the use of database credentials, including name, username, password, and hostname, which are typically stored in the "wp-config.php" file.

The default username and password for PHPMyAdmin are root and empty. For security reasons, it is recommended to change the default password. Method to change password: 1. Log in to PHPMyAdmin; 2. Select "privileges"; 3. Enter the new password and save it. When you forget your password, you can reset it by stopping the MySQL service and editing the configuration file: 1. Add the skip-grant-tables line; 2. Log in to the MySQL command line and reset the root password; 3. Refresh the permission table; 4. Delete skip-grant-tables line, restart the MySQL service.

Default location for PHPMyAdmin log files: Linux/Unix/macOS:/var/log/phpmyadminWindows: C:\xampp\phpMyAdmin\logs\ Log file purpose: Troubleshooting Audit Security

Steps to delete a data table in phpMyAdmin: Select the database and data table; click the "Action" tab; select the "Delete" option; confirm and perform the deletion operation.

Reasons and solutions for access denied by phpMyAdmin: Authentication failed: Check whether the username and password are correct. Server configuration error: adjust firewall settings and check whether the database port is correct. Permissions issue: Granting users access to the database. Session timeout: Refresh the browser page and reconnect. phpMyAdmin configuration error: Check the configuration file and file permissions to make sure the required Apache modules are enabled. Server issue: Wait for a while and try again or contact your hosting provider.

phpMyAdmin is susceptible to multiple vulnerabilities, including: 1. SQL injection vulnerability; 2. Cross-site scripting (XSS) vulnerability; 3. Remote code execution (RCE) vulnerability; 4. Local file inclusion (LFI) vulnerability; 5. Information disclosure Vulnerability; 6. Privilege escalation vulnerability.
