前言：MySQL監控也用過好多產品，包括zabbix、Lepus、PMM，想比較而言，PMM監控更加全面，安裝配置也更加簡單。

一、Server端安裝

server端安裝非常簡單，我們采用docker的方式來部署。

1.拉取鏡像

docker pull percona/pmm-server:latest

2.創建PMM數據容器

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.創建PMM服務器容器

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.查看服務啟動

[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.收集數據

pmm-admin add mysql --user=pmm --password=xxxx --port=3306

三、常用操作命令

PMM Client相關

[root@Mariadb-04 tmp]# pmm-admin --help

Usage:

pmm-admin [flags]

check-network Check network connectivity between client and server. 檢查網絡

ping Check if PMM server is alive. ping server端

start Start monitoring service.開啟服務

stop Stop monitoring service.停止服務

restart Restart monitoring service.重啟服務

show-passwords Show PMM Client password information (works offline).顯示客戶端密碼

purge Purge metrics data on PMM server.刪除PMM server端監控信息

repair Repair installation.重新安裝

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

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相關

[root@db-monitor-01 tmp]# docker --help

Usage: docker COMMAND

Options:

--config string Location of client config files (default "/root/.docker")

-D, --debug Enable debug mode

五、排錯

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"

類似于如上錯誤解決方法：

vim /etc/docker/daemon.json

{ "insecure-registries":["myregistry.example.com:5000"] }

Restart docker daemon

systemctl restart docker.service
