前言：MySQL監(jiān)控也用過好多產(chǎn)品岩馍，包括zabbix、Lepus抖韩、PMM蛀恩，想比較而言，PMM監(jiān)控更加全面帽蝶，安裝配置也更加簡(jiǎn)單赦肋。
一块攒、Server端安裝
server端安裝非常簡(jiǎn)單励稳，我們采用docker的方式來部署。
1.拉取鏡像
docker pull percona/pmm-server:latest
2.創(chuàng)建PMM數(shù)據(jù)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.創(chuàng)建PMM服務(wù)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.查看服務(wù)啟動(dòng)
[root@db-monitor-01 tmp]# ps -ef|grep docker

root 9660 2640 0 11:25 pts/1 00:00:00 grep --color=auto docker
二囱井、Client安裝
1.安裝rpm包
rpm -ivh pmm-client-1.9.1-1.el7.x86_64.rpm
2.連接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.收集數(shù)據(jù)
pmm-admin add mysql --user=pmm --password=xxxx --port=3306

Aug 17 21:07:24 localhost dockerd: time="2016-08-17T21:07:24.864612251+08:00" level=error msg="Attempting next endpoint for push after error: Get https://192.168.41.80:5001/v2/: dial tcp 192.168.41.80:5001: getsockopt: connection refused"
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"
類似于如上錯(cuò)誤解決方法：
vim /etc/docker/daemon.json
{ "insecure-registries":["myregistry.example.com:5000"] }
Restart docker daemon
systemctl restart docker.service
