Swoole and Workerman's optimization method for master-slave replication and read-write separation between PHP and MySQL

Swoole and Workerman's optimization method for master-slave replication and read-write separation of PHP and MySQL requires specific code examples

Abstract: With the increasing number of web applications With the continuous growth of complexity and user scale, the demand for database performance is also getting higher and higher. In PHP applications, master-slave replication and read-write separation are commonly used database optimization techniques. This article will introduce how to use the Swoole and Workerman frameworks to implement these technologies, while providing specific code examples.

1. Master-slave replication

Master-slave replication refers to executing database write operations (INSERT, UPDATE, DELETE) only on the master server, and then transmits the logs of these write operations to The slave server plays back the logs of these write operations on its own database. The advantage of this is that it can reduce the pressure on the main server and improve the read and write performance of the database.

Implementing master-slave replication in the Swoole and Workerman frameworks can be carried out through the following steps:

1. Configure the connection information of the master-slave server

Needs to be in the code Configure the connection information of the master server and slave server, including the address, port, user name, password, etc. of the master server.

2. Using the coroutine features provided by Swoole and Workerman

The Swoole and Workerman frameworks provide coroutine features to implement asynchronous task execution. When performing write operations on the main server, you can use coroutines to perform asynchronous operations to improve the processing capabilities of the main server.

3. Transmit the log of write operations to the slave server

After performing write operations on the master server, record these write operations and transmit them to the slave server. You can use the asynchronous network communication feature provided by Swoole to send the log of write operations to the slave server.

4. Perform write operation playback on the slave server

After the slave server receives the write operation log sent from the master server, it plays back these write operations and stores them in its own executed on the database.

The specific code examples are as follows:

// 主服务器的代码

SwooleCoroutine::create(function () {
    // 配置主服务器的连接信息
    $masterServer = new SwooleCoroutineMySQL();
    $masterServer->connect([
        'host' => '主服务器地址',
        'port' => '主服务器端口',
        'user' => '用户名',
        'password' => '密码',
        'database' => '数据库名',
    ]);

    // 执行写操作
    $result = $masterServer->query('INSERT INTO table_name (column1, column2) VALUES (value1, value2)');

    // 将写操作的日志传送给从服务器
    $slaveServer = new SwooleCoroutineMySQL();
    $slaveServer->connect([
        'host' => '从服务器地址',
        'port' => '从服务器端口',
        'user' => '用户名',
        'password' => '密码',
        'database' => '数据库名',
    ]);
    $slaveServer->query('INSERT INTO table_name (column1, column2) VALUES (value1, value2)');
});

// 从服务器的代码

SwooleCoroutine::create(function () {
    // 配置从服务器的连接信息
    $slaveServer = new SwooleCoroutineMySQL();
    $slaveServer->connect([
        'host' => '从服务器地址',
        'port' => '从服务器端口',
        'user' => '用户名',
        'password' => '密码',
        'database' => '数据库名',
    ]);

    // 接收主服务器传送过来的写操作日志
    $log = // 获取从主服务器传送过来的写操作日志

    // 执行写操作回放
    $slaveServer->query($log);
});

2. Reading and writing separation

Reading and writing separation refers to the separation of read operations (SELECT) and write operations (INSERT, UPDATE) of the database , DELETE) are executed on the master server and slave server respectively. The master server handles write operations, while the slave server handles read operations. The advantage of this is that it can improve the read and write performance of the database and increase the user's access speed.

Achieving read-write separation in the Swoole and Workerman frameworks can be carried out through the following steps:

1. Configure the connection information of the master server and slave server

Required Configure the connection information of the master server and slave server in the code, including the address, port, user name, password, etc. of the master server.

2. Select the server according to the operation type

Before each database operation, select the server to connect according to the operation type. If it is a read operation, connect to the slave server; if it is a write operation, connect to the master server.

3. Perform database operations

Perform corresponding database operations according to the selected server. For read operations, you can use the asynchronous network communication feature provided by Swoole to achieve concurrent processing.

The specific code examples are as follows:

// 读写分离的代码

SwooleCoroutine::create(function () {
    // 配置主服务器和从服务器的连接信息
    $masterServer = new SwooleCoroutineMySQL();
    $masterServer->connect([
        'host' => '主服务器地址',
        'port' => '主服务器端口',
        'user' => '用户名',
        'password' => '密码',
        'database' => '数据库名',
    ]);

    $slaveServer = new SwooleCoroutineMySQL();
    $slaveServer->connect([
        'host' => '从服务器地址',
        'port' => '从服务器端口',
        'user' => '用户名',
        'password' => '密码',
        'database' => '数据库名',
    ]);

    // 根据操作类型选择服务器
    $operationType = // 获取数据库操作类型（读或写）
    if ($operationType == 'read') {
        $server = $slaveServer;
    } else if ($operationType == 'write') {
        $server = $masterServer;
    }

    // 执行数据库操作
    $result = $server->query('SELECT * FROM table_name');
});

Summary: By using the Swoole and Workerman frameworks, we can easily implement the optimization method of master-slave replication and read-write separation of PHP and MySQL. These technologies can greatly improve database performance and increase user access speed. At the same time, the scientific and reasonable configuration and use of these technologies can better cope with the needs of large-scale Web applications and provide users with better services.
