PMM 监控MySQL

Posted 2020-10-17

Percona Monitoring and Management
也就是percona公司的数据库监控和管理的开源工具。
Percona Monitoring and Management (PMM) is a free and open-source platform for managing and monitoring mysql? and MongoDB? performance. You can run PMM in your own environment for maximum security and reliability. It provides thorough time-based analysis for MySQL, MariaDB? and MongoDB servers to ensure that your data works as efficiently as possible.
今天介绍pmm监控MySQL服务器
一、首先安装pmm server
我们这边使用docker安装pmm server 方便快捷
使用Docker运行PMM服务器
PMM服务器的Docker映像位于percona / pmm-server公共存储库中。如果您打算从Docker镜像运行PMM Server，则主机必须能够运行Docker 1.12.6或更高版本，并具有网络访问权限。
注意：确保主机的防火墙和路由规则不限制Docker容器

监控服务器安装docker
yum install -y docker
systemctl start docker
设置阿里云镜像库加速docker下载
mkdir -p /etc/docker
cat >/etc/docker/daemon.json <<EOF

{
"registry-mirrors": ["https://kli7phym.mirror.aliyuncs.com"]
}
EOF
systemctl daemon-reload
systemctl restart docker
第1步。拉取PMM服务器映像

docker pull percona / pmm-server：latest
第2步。创建一个PMM数据容器

docker create \
-v /opt/prometheus/data \
-v /opt/consul-data \
-v /var/lib/mysql \
-v /var/lib/grafana \
--name pmm-data \
percona/pmm-server:latest /bin/true

第三步。创建和运行 PMM Server Container

docker run -d -p 80:80 --volumes-from pmm-data --name pmm-server1 --restart always percona/pmm-server:latest
至此 pmm 构建完毕

二、被监控MySQL服务端安装pmm-client
(pmm-client与percona-toolkit请自行到percona官方下载)
在要被监控的MySQL服务器上安装
安装pmm-client
yum localinstall pmm-client-1.5.2-1.x86_64.rpm
安装percona工具
yum localinstall percona-toolkit-3.0.5-1.el7.x86_64.rpm

客户端连接pmm server
[[email protected] opt]# pmm-admin config --server 192.168.56.20
OK, PMM server is alive.

PMM Server | 192.168.56.20
Client Name | mysql
Client Address | 192.168.56.20
增加pmm-client监控账号
GRANT ALL PRIVILEGES ON?.?TO ‘pmm‘@‘192.168.56.%‘ IDENTIFIED BY ‘pmm‘;
flush privileges;

增加pmm客户端监控mysql到pmm服务器
pmm-admin add mysql --user pmm --password pmm --host 192.168.56.20 --port 3306

[[email protected] opt]# pmm-admin list
pmm-admin 1.5.2

PMM Server | 192.168.56.20
Client Name | mysql
Client Address | 192.168.56.20
Service Manager | linux-systemd

mysql:metrics mysql 42002 YES pmm:@tcp(192.168.56.20:3306)

访问pmm-server
192.168.56.20
