1 安装Percona Toolkit
去官网下载
2. 安装Anemometer
下载地址:https://github.com/box/Anemometer
3.下载PHP 相关模块
yum -y install php*
主要看这些模块:
php-common-5.3.3-1.el5
php-bcmath-5.3.3-1.el5
php-mysql-5.3.3-1.el5
php-dba-5.3.3-1.el5
php-cli-5.3.3-1.el5
php-gd-5.3.3-1.el5
php-5.3.3-1.el5
php-pdo-5.3.3-1.el5
4.启动apache服务
rpm -qa|grep http
httpd-2.2.3-45.el5
5..执行setup 脚本,创建用户:
[root@/var/www/html/anemometer]mysql -uroot -pxxx < install.sql
[root@/var/www/html/anemometer]mysql -uroot -pxxx
mysql > grant all on slow_query_log.* to ‘anemometer‘@‘%‘ identified by ‘123456‘;
mysql > grant all on slow_query_log.* to ‘anemometer‘@‘localhost‘ identified by ‘123456‘;
mysql > grant select on *.* to ‘anemometer‘@‘%‘;
mysql > grant all on slow_query_log.* to ‘anemometer‘@‘localhost‘;
mysql > grant select on *.* to ‘anemometer‘@‘localhost‘;
6.修改PHP配置文件:
vim /etc/php.ini
7.修改WEB页面:
cd /var/www/html/anemometer/conf
cp sample.config.inc.php config.inc.php
vi config.inc.php
以及
8. 修改APACHE配置文件“
cat /etc/httpd/conf/httpd.conf |grep "ServerName" |grep -v ‘^#‘
ServerName 10.1.11.99:80
重启HTTP,访问不了,报错如下:
tail -f /etc/httpd/logs/error_log
解决方法如下:
9:访问页面:
10.1.11.99/anemometer
11.导入慢查询日志
pt-query-digest --user=anemometer --password=123456 --socket=/tmp/mysql3306.sock --review h=localhost,D=slow_query_log,t=global_query_review --history h=localhost,D=slow_query_log,t=global_query_review_history --no-report --limit=0% --filter=" \$event->{Bytes} = length(\$event->{arg}) and \$event->{hostname}=\"$HOSTNAME\"" /opt/soft/slow_query_2015-09-24.log

使用Anemometer基于pt-query-digest将MySQL慢查询可视化
