本文实例讲述了PHP实现的redis主从数据库状态检测功能。分享给大家供大家参考，具体如下：
实例：
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( $host )无法连接 ！
";
continue;
}
if(!empty($db_key['password'])) {
$pass = $redis->auth($db_key['password']);
if(!$pass) {
$content .= "redis从数据库( $host )密码错误 ！
";
continue;
}
}
try {
$config = $redis->info();
if('up' == $config['master_link_status']) {
} else {
$content .= "redis从数据库( $host )挂掉了！
";
}
}
catch(RedisException $e)
{
$content .= "redis从数据库( $host )报错：" . $e->getMessage()."
";
}
}
//若报错信息不为空，发送报错邮件
if(!empty($content)) {
$title = '主从redis数据库状态检测报错 ';
$content = date("Y-m-d H:i:s",time()) . "
" . $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("
", "\n", $content);
$message .= $content;
error_log($message,3,"error.log");
}
}
