这篇文章主要介绍了php在linux下检测mysql同步状态的方法,是Linux下使用php检测mysql同步状态的实用技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了php在linux下检测mysql同步状态的方法。分享给大家供大家参考。具体分析如下：
这里通过两个实例来介绍mysql同步状态检测实现方法。代码如下:
复制代码 代码如下:
#!/bin/sh
#check MySQL_Slave Status
#crontab time 00:10
MYSQL_USER="root"
MYSQL_PWD="123456"
MYSQL_SLAVE_LOG="/tmp/check_mysql_slave.log"
EMAIL="1351010****@139.com"
MYSQL_PORT=`netstat -na|grep "LISTEN"|grep "3306"|awk -F[:" "]+ '{print $5}'`
MYSQL_IP=`ifconfig eth0|grep "inet addr" | awk -F[:" "]+ '{print $4}'`
MYSQL_SLAVE_STATUS=$(/usr/local/webserver/mysql/bin/mysql -u root -psylc23hua -S /tmp/mysql.sock -e
"show slave statusG" | grep -i "running")
IO_ENV=`echo $MYSQL_SLAVE_STATUS | grep IO | awk ' {print $2}'`
SQL_ENV=`echo $MYSQL_SLAVE_STATUS | grep SQL | awk '{print $2}'`
NOW=$(date -d today +'%Y-%m-%d %H:%M:%S')
if [ "$MYSQL_PORT" = "3306" ];then
echo "mysql is running!"
else
mail -s "warn!server: $MYSQL_IP mysql is down" "$EMAIL"
fi
if [ "$IO_ENV" = "Yes" -a "$SQL_ENV" = "Yes" ];then
echo "Slave is running!"
else
echo "[ $NOW ] Slave is not running!" >> "$MYSQL_SLAVE_LOG"
cat "$MYSQL_SLAVE_LOG" | mail -s "WARN! ${MySQL_IP}_replicate_error" "$EMAIL"
fi
exit 0
复制代码 代码如下:
if(emptyempty($_REQUEST["key"])) die(':) missing key');
if($_REQUEST["key"] != 'xupeng') die(':) error key');
include("mysql_instance.php");
include("check_status_api.php");
define("USERNAME", "用户名");
define("PASSWORD", "密码");
define("DEBUGMODE", false);
$instances = get_instances();
if($instances){
echo
END;
echo "

if(!DEBUGMODE){
echo "
n";
}else{
echo "
n";
}
foreach($instances as $host){
$res = check_mysql_replication_status($host, USERNAME, PASSWORD);
if(!DEBUGMODE){
switch($res["result"]){
case -4:
$memo = "未知异常";
break;
case -3:
$memo = "查询失败";
break;
case -2:
$memo = "无法连接端口";
break;
case -1:
$memo = "状态未知";
break;
case 0:
$memo = "OK";
break;
case 1:
$memo = "同步失败";
if($res["Slave_IO_Running"] "Yes"){
$memo .= $res["Last_IO_Error"] . "(" . $res
["Last_IO_Errno"] . ")";
}
if($res["Slave_SQL_Running"] "Yes"){
$memo .= $res["Last_SQL_Error"] . "(" . $res
["Last_SQL_Errno"] . ")";
}
break;
case 2:
$memo = "数据库未设置同步";
break;
}
echo "
n";
}else{
echo "
n";
}
}
echo "
