Example:
<?php /** * 检测多个主从redis数据库是否挂掉 * 建立从数据库$redis_db的二维数组,内容包含每个从服务器的配置数据 */ header("Content-Type: text/html; charset=utf-8"); set_time_limit(0); $redis_db = array( 'db1'=>array( 'hostname' => '127.0.0.1', 'port' => 6379, 'password' => '', ), 'db2'=>array( 'hostname' => '192.168.2.179', 'port' => 6379, 'password' => '111111', ), ); $content = ''; foreach ($redis_db as $db_key) { $host = $db_key['hostname']; $port = $db_key['port']; $redis = new Redis(); //连接本地的 Redis 服务 $status= $redis->connect($host, $port); if(!$status) { $content .= "redis从数据库( $host )无法连接 ! <br/>"; continue; } if(!empty($db_key['password'])) { $pass = $redis->auth($db_key['password']); if(!$pass) { $content .= "redis从数据库( $host )密码错误 ! <br/>"; continue; } } try { $config = $redis->info(); if('up' == $config['master_link_status']) { } else { $content .= "redis从数据库( $host )挂掉了! <br/>"; } } catch(RedisException $e) { $content .= "redis从数据库( $host )报错:" . $e->getMessage()."<br/>"; } } //若报错信息不为空,发送报错邮件 if(!empty($content)) { $title = '主从redis数据库状态检测报错 '; $content = date("Y-m-d H:i:s",time()) . "<br/>" . $content; $sendurl = "http://localhost/api.com/test.php?title=".$title."&content=".$content; $result = file_get_contents($sendurl); if('ok' != $result) { $message = date("Y-m-d H:i:s",time()).' redisSlave.php 主从redis数据库状态检测报错 邮件发送失败!'."\n"; $content = str_replace("<br/>", "\n", $content); $message .= $content; error_log($message,3,"error.log"); } }##Related recommendations:
