首先安装lnmp环境,要求php-5.3以上版本. 参考:http://isadba.com/?p=82 或者参考http://isadba.com/?p=572 然后下载anemometer git clonehttps://github.com/box

然后下载anemometer
git clone https://github.com/box/anemometer.git anemometer
配置lnmp将下载下来的anemometer部署到lamp上面,可以通过web打开页面,会提示你没有配置网站.

安装percona的toolkit工具
yum install
yum install percona-toolkit -y
修改配置文件
cd /var/www/anemometer/conf/
cp sample.config.inc.php config.inc.php
修改35-40行的数据库配置,连接到anemometer的数据库,当然,你数据库也需要授权.
#使用pt-query-digest工具,将一些慢查询数据导入数据库
pt-query-digest –user=anemometer –password=anemometerpass–review h=192.168.11.28,d=slow_query_log,t=global_query_review \
–history h=192.168.11.28,d=slow_query_log,t=global_query_review_history \
–no-report –limit=0% –filter=” \$event->{bytes} = length(\$event->{arg}) and \$event->{hostname}=\”$hostname\” \
/usr/local/mariamysql/data/localhost-slow.log
执行命令以后,h=192.168.11.28,d=slow_query_log,t=global_query_review_history和global_query_review表已经已经有一些数据了,你可以尝试手工查询.
现在可以再通过web访问anemometer,就能看到相关信息了.
到这一步,anemometer算是跑通了,下一步就是真正的部署使用.
现在的环境是,有多台mysql服务器的slow log需要监控.
我们有三种方案.
1、手工导入的install.sql里面的global_query_review_history表包含了hostname_max和db_max,通过hostname_max区分把多个数据源存放到一个表里.
2、每台mysql把处理后的binlog数据放到当前服务器,然后anemometer连接对应的服务器获取数据.
3、所有的mysql把处理后的binlog数据统一存放到anemometer所在的数据库上,然后通过表名或者数据库名字区分.
如果选择第二种或者第三种方案,需要定义多个数据源,并且anemometer_collect.sh.里面对应的history_db_name要对应.
在conf/config.inc.php总修改数据源的配置,注意可以不同的数据源指向的是不同的db,一般可以按照项目区分.

$conf['datasources']['192.168.11.28'] = array('host' => '192.168.11.28','port' => 3306,'db' => 'slow_query_log','user' => 'anemometer','password' => 'anemometerpass','tables' => array('global_query_review' => 'fact','global_query_review_history' => 'dimension'),'source_type' => 'slow_query_log');$conf['datasources']['192.168.11.17'] = array('host' => '192.168.11.28','port' => 3306,'db' => 'slow_query_log_192_168_11_17','user' => 'anemometer','password' => 'anemometerpass','tables' => array('global_query_review' => 'fact','global_query_review_history' => 'dimension'),'source_type' => 'slow_query_log');在所有mysql上部署scripts/anemometer_collect.sh收集慢查询日志.
anemometer_collect.sh脚本有几个注意点
1、path里面是否有mysql的bin路径
2、如果history_db_name需要根据不同机器做修改,和config.inc.php定义的对应
3、注意原始慢查询日志路径是否正确
4、通过设置long_query_time设置慢查询的时长
5、所有mysql服务器上需要安装percona-toolkit的工具箱.
并且在anemometer_collect.sh当前目录下增加下面两个配置文件.
连接到本地mysql服务器的账号,需要有super权限.
[root@localhost scripts]# cat anemometer-localhost.cnf[client]user=rootpassword=host=localhostsocket=/tmp/mysql.sock连接到anemometer服务器数据库的账号,需要对anemometer_collect.sh脚本中history_db_name对应的数据库有all privileges权限.
[root@localhost scripts]# cat anemometer-server.cnf[client]user=anemometerpassword=anemometerpass使用下面命令调试脚本.
sh -x ./anemometer_collect.sh --interval 30 --history-db-host 192.168.11.17 --defaults-file ./anemometer-localhost.cnf --history-defaults-file ./anemometer-server.cnf调试通过以后,在crontab添加如下命令,实现定期采集慢查询日志到数据库存储.间隔可以根据自己的需求设置,我的设置基本上是采集所有的慢查询日志.
*/1 * * * * /opt/anemometer_collect.sh –interval 59 –history-db-host 192.168.11.28 –defaults-file /opt/anemometer-localhost.cnf –history-defaults-file /opt/anemometer-server.cnf
由于anemometer不能跟踪sql是哪个账号,哪个主机的请求,所以我们有必要保存原始日志,来做例外分析.
下面是我修改后的anemometer_collect.sh,增加了可定制的慢查询问题,mysql path,慢查询时长变量设置,保存历史的慢查询日志.
