Anemometer 安装使用&过程中遇到的问题

项目地址:https://github.com/box/Anemometer

演示地址:http://lab.fordba.com/anemometer/

Anemometer 是一个图形化显示从MySQL慢日志的工具。

结合pt-query-digest,Anemometer可以很轻松的帮你去分析慢查询日志,让你很容易就能找到哪些SQL需要优化。

2、安装 pt-query-digest工具

下载安装:

 https://www.percona.com/downloads/percona-toolkit/3.0.13/binary/redhat/7/x86_64/percona-toolkit-3.0.13-re85ce15-el7-x86_64-bundle.tar

 Wget https://www.percona.com/downloads/percona-toolkit/3.0.13/binary/redhat/7/x86_64/percona-toolkit-3.0.13-1.el7.x86_64.rpm

安装方式:

[root@localhost pt]# rpm -ivh percona-toolkit-3.0.10-1.el7.x86_64.rpm

警告:percona-toolkit-3.0.10-1.el7.x86_64.rpm: 头V4 DSA/SHA1 Signature, 密钥 ID cd2efd2a: NOKEY

验证 pt 工具安装成功:

[root@localhost data]# pt-query-digest --version

pt-query-digest 3.0.10
[root@localhost data]#

 

3、anemometer 依赖的 LAMP 环境

A、关闭 selinx

setenforce 0

sed -i 's/enforcing/disabled/g' /etc/sysconfig/selinux

B、打开防火墙的443,13306,80端口

iptables -I INPUT -p tcp --dport 443 -j ACCEPT

iptables -I INPUT -p tcp --dport 80 -j ACCEPT

iptables -I INPUT -p tcp --dport 13306 -j ACCEPT

# service iptables save

systemclt save iptables

C、安装 Apache

yum install httpd httpd-devel -y

D、安装 php

yum install -y php php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt libmcrypt-devel php-fpm php-dba

E、修改时区

vim /etc/php.ini

修改为

date.timezone = PRC # 注意,前面逗号去掉

F、验证 httpd 服务的状态

[root@localhost pt]# systemctl start httpd.  #启动

[root@localhost pt]# systemctl stop httpd    #关闭

[root@localhost pt]# systemctl restart httpd #重启

[root@localhost pt]# systemctl status httpd  #查看

Anemometer 安装使用&过程中遇到的问题_第1张图片

 

4、安装配置 anemometer

A、下载

下载:

git clone https://github.com/box/Anemometer.git

移动到对应路径:

mv Anemometer /var/www/html/anemometer

B、执行存储日志信息的 MySQL实例的初始化Anemometer 安装使用&过程中遇到的问题_第2张图片

执行 install.sql:

[root@localhost anemometer]# mysql -hlocalhost -uroot -proot -P3306 --default-character-set=utf8 < install.sql

该 install.sql 中创建的库slow_query_log,即实际慢日志记录所写入、存储的库。每个产生慢日志的 database源可以对应anemometer 写入实例中的一个 database,即修改 install.sql 内容。

问题 1:

执行脚本遇到问题,修改 用于记录分析后慢日志记录的 MySQL 实例的 sql_mode

root@localhost|mysql>select @@sql_mode;
+------------+
| @@sql_mode |
+------------+
|'ONLY_FULL_GROUP_BY,NO_AUTO_VALUE_ON_ZERO,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'|
+------------+
1 row in set (0.00 sec)

解决办法:

修改sql_mode 为空:

set global sql_mode='';

C、授权

在目标数据库(anemometer 应用所部署在的MySQL服务器,该 MySQL 用于存储分析统计后的 slow log 记录)上为 anemometer 应用授予相应权限

root@localhost|mysql>grant all privileges on *.* to 'anemometer'@'192.168.225.131';

Query OK, 0 rows affected (0.02 sec)  #ip 为anemometer应用部署的主机ip,我这里 anemometer和用于存储解析后的慢日志信息的 MySQL实例,在同一台机器上。

D、修改配置文件

增加explain读取用户密码信息

[root@localhost pt]# cd /var/www/html/anemometer/

[root@localhost anemometer]# cp conf/sample.config.inc.php conf/config.inc.php

[root@localhost anemometer]#  vim conf/config.inc.php

Anemometer 安装使用&过程中遇到的问题_第3张图片

E、修改配置文件

pt 工具解析后的慢日志信息存储实例相关信息

该配置文件指明,pt 分析后的慢日志信息存储的MySQL 实例和 user 相关信息

[root@localhost conf]# pwd

/var/www/html/anemometer/conf

vim datasource_localhost.inc.php

Anemometer 安装使用&过程中遇到的问题_第4张图片

F、访问

http://192.168.225.131/anemometer 

# IP 是部署 anemometer 应用的服务器 IP

Anemometer 安装使用&过程中遇到的问题_第5张图片

目前还没数据。因为还未导入目标 MySQL 实例的慢SQL信息。

 

G、导入慢日志

慢查询主机推送格式:

For pt-query-digest version < 2.2

pt-query-digest --user=anemometer --password=123456 \
--review h=db.example.com,D=slow_query_log,t=global_query_review \
--review-history h=db.example.com,D=slow_query_log,t=global_query_review_history \
--no-report --limit=0% \
--filter=" \$event->{Bytes} = length(\$event->{arg}) and \$event->{hostname}=\"$HOSTNAME\"" \
/var/lib/mysql/db.example.com-slow.log

For pt-query-digest version >= 2.2

pt-query-digest --user=anemometer --password=123456 \ 
--review h=192.168.225.129,P=3306,D=slow_query_log,t=global_query_review \
--history h=db.example.com,D=slow_query_log,t=global_query_review_history \
--no-report --limit=0% \
--filter=" \$event->{Bytes} = length(\$event->{arg}) and \$event->{hostname}=\"$HOSTNAME\"" \
/data/mysql/slow.log

环境实际执行命令如下:

pt-query-digest --user=root --password=xxxx --review h=localhost,P=3306,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\"" /data/contract-trade_slowlog_20190927.log

再次访问 anemometer,并执行查询:

Anemometer 安装使用&过程中遇到的问题_第6张图片

tips慢日志推送脚本示例:

#!/bin/bash
anemometer_host="127.0.0.1"          # anemometer应用服务器
anemometer_user="root"                   # anemometer 上部署用于存存储分析的慢日志信息的 MySQL 实例用户
anemometer_password="123456"    # anemometer 的 MySQL用户密码
anemometer_port=3306                    # anemometer 的 MySQL实例端口
anemometer_db="slow_query_log"  # anemometer 存储日志的 database

# 获取慢日志路径
slowlog_dir=/data/slowlog/
pt-query-digest=/bin/pt-query-digest
slowlog_file=$slowlog_dir/contract-trade_slowlog_`date +%Y%m%d`.log
pt_query_digest="$pt-query-digest —user=$slowlog_file —password=$anemometer_password --review h=$anemometer_host,P=$anemometer_port,D=$anemometer_db,t=global_query_review --history h=$anemometer_port,D=$anemometer_db,t=global_query_review_history --no-report --limit=0% --filter=" \$event->{Bytes} = length(\$event->{arg}) and \$event->{hostname}=\"$HOSTNAME\"" $slowlog_file

#删除两天前的日志
cd $slowlog_dir
/usr/bin/find ./ -name 'contract-trade_slowlog_*.log' -mtime +2|xargs rm -rf

 

配置过程中遇到的问题:

问题 2 :

[root@localhost anemometer]# pt-query-digest --user=root --password=root --review h=localhost,P=3306,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\"” /data/contract-trade_slowlog_20190927.log

Reading from STDIN ...

原因:

日志路径错误

解决方法:

[root@localhost anemometer]# pt-query-digest --user=root --password=root --review h=localhost,P=3306,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\"" ./contract-trade_slowlog_20190927.log

[root@localhost anemometer]#

 

 

问题 3 :

Pipeline process 5 (iteration) caused an error: DBD::mysql::st execute failed: Out of range value for column 'checksum' at row 1 [for Statement "REPLACE INTO `slow_query_log`.`global_query_review_history`(`checksum`, `sample`, `hostname_max`, `db_max`, `ts_min`, `ts_max`, `ts_cnt`, `query_time_sum`, 

……

Will retry pipeline process 4 (iteration) 2 more times.

……

Terminating pipeline because process 4 (iteration) caused too many errors.

截图如下:

原因:

sql_mode开始并未设为空,因为某些原因,也无法修改该MySQL实例的 sql_mode

root@localhost|(none)>show variables like 'sql_mode';
+---------------+-----------------------------------------------------------------------------------------------------------+
| Variable_name | Value                                                                                                     |

| sql_mode      | STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |
+---------------+-----------------------------------------------------------------------------------------------------------+
1 row in set (0.01 sec)

Pt 解析后的 checksum 值为字符串,

Anemometer 安装使用&过程中遇到的问题_第7张图片

而表的字段类型为 bigint。

处理方法:

alter table global_query_review_history modify checksum varchar(100) not null;

 

 

问题 4:

Pipeline process 5 (iteration) caused an error: Redundant argument in sprintf at /usr/bin/pt-query-digest line 2556. Will retry pipeline process 4 (iteration) 2 more times. Pipeline process 5 (iteration) caused an error: Redundant argument in sprintf at /usr/bin/pt-query-digest line 2556. Will retry pipeline process 4 (iteration) 2 more times. The pipeline caused an error: Pipeline process 5 (iteration) caused an error: Redundant argument in sprintf at /usr/bin/pt-query-digest line 2556. Terminating pipeline because process 4 (iteration) caused too many errors.

原因:

旧版本pt-query-digest 的 bug

解决方法:

# wget percona.com/get/percona-toolkit.tar.gz

# tar zxvf percona-toolkit-.tar.gz

# cd percona-toolkit-

# perl Makefile.PL

# make

# make test

# make install

 

 

问题 5:

执行perl Makefile.PL 报错

原因:

缺少依赖包

解决办法:

yum install perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker
