前言:PMM作为MySQL的监控系统,主要是用promethues和grafana两个工具进行定制的监控。

PMM分两个版本:PMM1和PMM2,PMM1控制力度比较好一些,PMM2界面比较丰富友好一些。该工具分PMM Server和PMM Client。

PMM2的安装

安装PMM Server with Docker

1.拉取镜像

sudo docker pull percona/pmm-server:2

2.创建一个永久数据容器

sudo docker create --volume /srv \
--name pmm-data percona/pmm-server:2 /bin/true

3.运行镜像,启动PMM Server

sudo docker run --detach --restart always \
--publish 443:443 --publish 80:80 \
--volumes-from pmm-data --name pmm-server \
percona/pmm-server:2

4.web浏览器中,访问服务器http://xx.xx.xx.xx:80,访问默认用户密码:admin / admin,第一次进去要修改下密码。

安装PMM Client

1.用yum安装,配置仓库

sudo yum install -y https://repo.percona.com/yum/percona-release-latest.noarch.rpm

2.安装PMM Client 包

sudo yum install -y pmm2-client

 或直接用rpm包安装

1.下载rpm包
wget https://downloads.percona.com/downloads/pmm2/2.16.0/binary/redhat/7/x86_64/pmm2-client-2.16.0-6.el7.x86_64.rpm

2.安装rpm包
rpm -ivh pmm2-client-2.16.0-6.el7.x86_64.rpm

配置

1.注册节点到PMM服务

pmm-admin config --server-insecure-tls --server-url=https://admin:admin@X.X.X.X:443

  1)x.x.x.x is the address of your PMM Server.

  2)443是默认端口

  3)admin/admin是登录PMM Server页面的用户名密码

2.配置和加服务,首先创建用户

CREATE USER \'pmm\'@\'localhost\' IDENTIFIED BY \'pass\' WITH MAX_USER_CONNECTIONS 10;
GRANT SELECT, PROCESS, SUPER, REPLICATION CLIENT, RELOAD ON *.* TO \'pmm\'@\'localhost\';

3.选择和配置一个数据源

   .慢查询数据源,需配置的配置文件参数(预备工作)

slow_query_log=ON
log_output=FILE
long_query_time=1
log_slow_admin_statements=ON
log_slow_slave_statements=ON
#动态设置
SET GLOBAL slow_query_log = 1; SET GLOBAL log_output = \'FILE\'; SET GLOBAL long_query_time = 1; SET GLOBAL log_slow_admin_statements = 1; SET GLOBAL log_slow_slave_statements = 1;

   .Performance Schema数据源,需配置的配置文件参数(预备工作)

performance_schema=ON
performance-schema-instrument=\'statement/%=ON\'
performance-schema-consumer-statements-digest=ON
innodb_monitor_enable=all

#动态设置,performance_schema cannot be set in a session and must be set at server start-up
UPDATE performance_schema.setup_consumers
SET ENABLED = \'YES\' WHERE NAME LIKE \'%statements%\';
SET GLOBAL innodb_monitor_enable = all;

4.添加MySQL Service

pmm-admin add mysql --query-source=slowlog --size-slow-logs=1GB --username=pmm --password=pass MYSQL_NODE 192.168.1.123:3306
pmm-admin add mysql --query-source=perfschema --username=pmm --password=pass --service-name=MYSQL_NODE 192.168.1.123:3306
#服务名(MYSQL_NODE) and 被监控的服务地址/端口 (191.168.1.123:3306).

5.检查服务

pmm-admin inventory list services

6.从监控删除服务

pmm-admin remove <service-type> <service-name>

维护工作

删除PMM Server

1.停止pmm-server容器
docker stop pmm-server 2.删除容器 docker rm pmm-server pmm-data 3.删除镜像 docker rmi $(docker images | grep "percona/pmm-server" | awk {\'print $3\'})
