前言：MySQL監(jiān)控也用過好多產(chǎn)品，包括zabbix、Lepus、PMM，想比較而言，PMM監(jiān)控更加全面，安裝配置也更加簡(jiǎn)單。

一、Server端安裝

server端安裝非常簡(jiǎn)單，我們采用docker的方式來(lái)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 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 8538 8531 0 10:38 ? 00:00:03 /usr/bin/docker-containerd-current -l unix:///var/run/docker/libcontainerd/docker-containerd.sock --metrics-interval=0 --start-timeout 2m --state-dir /var/run/docker/libcontainerd/containerd --shim docker-containerd-shim --runtime docker-runc --runtime-args --systemd-cgroup=true

root 9095 8531 0 10:56 ? 00:00:00 /usr/libexec/docker/docker-proxy-current -proto tcp -host-ip 0.0.0.0 -host-port 80 -container-ip 172.17.0.2 -container-port 80

root 9100 8538 0 10:56 ? 00:00:00 /usr/bin/docker-containerd-shim-current 7c5656534fed82420cba57ec9ab3f929b242802dae2dcf3fbb400859d2517b6d /var/run/docker/libcontainerd/7c5656534fed82420cba57ec9ab3f929b242802dae2dcf3fbb400859d2517b6d /usr/libexec/docker/docker-runc-current

root 9660 2640 0 11:25 pts/1 00:00:00 grep --color=auto docker

二、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

三、常用操作命令

PMM Client相關(guān)

purge Purge metrics data on PMM server.刪除PMM server端監(jiān)控信息

repair Repair installation.重新安裝

uninstall Removes all monitoring services with the best effort.刪除所有服務(wù)

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

五、排錯(cuò)

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
