這篇文章主要介紹了PHP實現的mysql主從資料庫狀態檢測功能,結合具體執行個體形式分析了php檢測多個mysql主從資料庫連接狀態的相關實現技巧,需要的朋友可以參考下
本文執行個體講述了PHP實現的mysql主從資料庫狀態檢測功能。分享給大家供大家參考,具體如下:
執行個體:
<?php/** * 檢測多個主從資料庫是否掛掉 * 建立從資料庫$slave_db的二維數組,內容包含每個從伺服器的配置資料 */header("Content-Type: text/html; charset=utf-8");set_time_limit(0);$slave_db = array( 'db1'=>array( 'hostname' => '127.0.0.1', 'port' => 3306, 'database' => 'test', 'username' => 'root', 'password' => '111111', 'charset' => 'utf8', ), 'db2'=>array( 'hostname' => '127.0.0.2', 'port' => 3306, 'database' => 'test', 'username' => 'root', 'password' => '111111', 'charset' => 'utf8', ),);$content = '';foreach ($slave_db as $db_key) { $host = $db_key['hostname']; $port = $db_key['port']; $db_user = $db_key['username']; $db_pass = $db_key['password']; $slave_link = mysql_connect($host,$db_user,$db_pass); if(mysql_errno()) { $content .= "從資料庫( $host )無法串連 ! <br/>"; $content .= mysql_error() . "<br/>"; continue; } $sql = "show slave status"; $result = mysql_query($sql, $slave_link); $row = mysql_fetch_assoc($result); $Slave_IO_Running = $row['Slave_IO_Running']; $Slave_SQL_Running = $row['Slave_SQL_Running']; if ('Yes' == $Slave_IO_Running && 'Yes' == $Slave_SQL_Running) { } else { $content .= "從資料庫( $host )掛掉了! <br/>"; } mysql_free_result($result); mysql_close($slave_link);}//若報錯資訊不為空白,發送報錯郵件if(!empty($content)) { $title = '主從資料庫狀態檢測報錯 '; $content = date("Y-m-d H:i:s",time()) .

<?php$title = $_GET['title'];$content = $_GET['content'];$content = str_replace("<br/>", "\n", $content);error_log($title."\n",3,'error.log');error_log($content."\n",3,'error.log');echo 'ok';
