前言：MySQL监控也用过好多产品，包括zabbix、Lepus、PMM，想比较而言，PMM监控更加全面，安装配置也更加简单。
一、Server端安装
server端安装非常简单，我们采用docker的方式来部署。
1.拉取镜像
docker pull percona/pmm-server:latest
2.创建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
3.创建PMM服务器容器
docker run -d -p 80:80 \
--volumes-from pmm-data \
--name pmm-server \
-e SERVER_USER=test \
-e SERVER_PASSWORD=test \
-e ORCHESTRATOR_ENABLED=true \
--restart always \
percona/pmm-server:latest
4.查看服务启动
[root@db-monitor-01 tmp]# ps -ef|grep docker
root 8531 1 0 10:38 ? 00:00:05 /usr/bin/dockerd-current --add-runtime docker-runc=/usr/libexec/docker/docker-runc-current --default-runtime=docker-runc --exec-opt native.cgroupdriver=systemd --userland-proxy-path=/usr/libexec/docker/docker-proxy-current --seccomp-profile=/etc/docker/seccomp.json --selinux-enabled --log-driver=journald --signature-verification=false --storage-driver overlay2

root 9660 2640 0 11:25 pts/1 00:00:00 grep --color=auto docker
二、Client安装
1.安装rpm包
rpm -ivh pmm-client-1.9.1-1.el7.x86_64.rpm
2.连接server
pmm-admin config --server server_ip --bind-address=client_ip --client-address=client_ip --server-user=admin --server-password=xxx --client-name=xxx
3.收集数据
pmm-admin add mysql --user=pmm --password=xxxx --port=3306
三、常用操作命令
PMM Client相关
[root@Mariadb-04 tmp]# pmm-admin --help
Usage:
pmm-admin [flags]
pmm-admin [command]

ping Check if PMM server is alive. ping server端
start Start monitoring service.开启服务
stop Stop monitoring service.停止服务
restart Restart monitoring service.重启服务
show-passwords Show PMM Client password information (works offline).显示客户端密码
purge Purge metrics data on PMM server.删除PMM server端监控信息
repair Repair installation.重新安装
uninstall Removes all monitoring services with the best effort.删除所有服务
help Help about any command
Flags:
-c, --config-file string PMM config file (default "/usr/local/percona/pmm-client/pmm.yml")
-h, --help help for pmm-admin
--verbose verbose output
-v, --version show version
Use "pmm-admin [command] --help" for more information about a command.
Docker相关

Aug 17 21:07:24 localhost dockerd: time="2016-08-17T21:07:24.864884008+08:00" level=error msg="Attempting next endpoint for push after error: Get https://192.168.41.80:5001/v1/_ping: dial tcp 192.168.41.80:5001: getsockopt: connection refused"
类似于如上错误解决方法：
vim /etc/docker/daemon.json
{ "insecure-registries":["myregistry.example.com:5000"] }
Restart docker daemon
systemctl restart docker.service
