zabbix通过php脚本模拟业务访问redis验证nosql的可用性
背景： redis通过shell脚本进行监控，没有问题，应用报警连不上redis，此时需要通过php模拟web环境进行redis的操作来确认web服务器是否能正常和redis通信 1.配置nginx，让监控redis的php脚本能通过url访问到redis # nginx.conf的配置修改 location ~ ^/php { root /data/www/html; location ~ php(.+\.php)(.*)$ { fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; expires -1; if ($request_uri ~ "^(.*)(\?.*)$") { set $path_info $1; } fastcgi_param PATH_INFO $path_info; set $path_info $request_uri; } index watchphp.php; } 2.编写监控脚本 # mkdir -p /data/www/html/php # vim /data/www/html/php/redis_monitor.php <?php /* redis_monitor.php author:reblue520 通过类似 http://127.0.0.1/php/eus_redis_monitor.php?func_name='store_redis' php web的访问来判断redis的可用性 */ //通过获取/data/www/machine_no/.machine_no获取机房进行redis的判断 //$machine_no = trim(file_get_contents("/data/www/machine_no/.machine_no")); //empty($machineNo) && $machine_no = 'ws'; //echo "machineno=$machine_no"; // 获取机房编号 /* $file_path = "/data/www/machine_no/.machine_no"; if(file_exists($file_path)) { $machine_no = file_get_contents($file_path); $machine_no= str_replace("\r\n","<br />",$machine_no); if (empty($machine_no)){ $machine_no = 'ws'; } } */ function conn_redis($redis_domain, $redis_port, $redis_pass){ //创建 Redis 对象 $redis = new Redis(); // global $redis; $redis->connect($redis_domain, $redis_port); $redis->auth($redis_pass); //设置 redis 字符串数据，并返回该设置的字符串 $redis->set("tutorial-name", "Redis-tutorial"); $result = $redis->get("tutorial-name"); return $result; } function eus_store_redis() { global $machine_no; $res = conn_redis('store-cart.chinasoft.com', 6379, 'pass'); if ($res == "Redis-tutorial") { echo "store_success"; }else { echo "store_fail"; } } function ws_store_redis() { global $machine_no; $res = conn_redis('cart.chinasoft.com', 6379, 'pass'); if ($res == "Redis-tutorial") { echo "store_success"; }else { echo "store_fail"; } } function platform_redis() { $res = conn_redis('cbs_out.chinasoft.com', 9376, 'pass'); if ($res == "Redis-tutorial") { echo "platform_success"; }else { echo "platform_fail"; } } function cbs_redis() { $res = conn_redis('cbs_out.chinasoft.com', 9376, 'pass'); if ($res == "Redis-tutorial") { echo "cbs_success"; }else { echo "cbs_fail"; } } // 通过get参数获取不同的应用redis $func_name = $_GET['func_name']; if ($func_name == "store_redis") { eus_store_redis(); }elseif($func_name == "platform_redis"){ platform_redis(); }elseif($func_name == "cbs_redis"){ cbs_redis(); } ?> 3.监控的配置 [root@zabbix:/data/www/html/php]# cat /usr/local/zabbix_agents_3.2.0/conf/zabbix_agentd/redis_monitor.conf UserParameter=redis.store_redis,/usr/bin/curl -s http://127.0.0.1/php/eus_redis_monitor.php?func_name='store_redis' UserParameter=redis.cbs_redis,/usr/bin/curl -s http://127.0.0.1/php/eus_redis_monitor.php?func_name='cbs_redis' UserParameter=redis.platform_redis,/usr/bin/curl -s http://127.0.0.1/php/eus_redis_monitor.php?func_name='platform_redis' 4.模板
