传统数仓

###### 服务器信息

### 生产环境

ip     101.192.3.179

### 开发环境

ip     101.192.7.76

###### pmm构构图

pmm监控工具自带监控linux,mysql,mongodb
pmm重要组件 grafana,prometheus
https://grafana.com/ //grafana作为数据展示
https://prometheus.io/ //数据采集数据库

###### mysql数据库服务配置

https://www.percona.com/doc/percona-monitoring-and-management/conf-mysql.html

innodb_monitor_enable = all

docker run -d -p 80:80 --volumes-from pmm-data --name pmm-server -e server_user=pmm -e server_password=123456 -e metrics_memory=786432 --restart always --init percona/pmm-server:1.2.0

pmm 1.2.0需要加 metrics_memory=786432

https://www.percona.com/forums/questions-discussions/percona-monitoring-and-management/49047-pmm-1-2-0-a-lot-of-data-is-not-shown

###### pmm监控工具安装
参考:https://www.percona.com/doc/percona-monitoring-and-management/deploy/index.html
       https://docs.docker.com/engine/installation/linux/centos

### 第一步:安装docker

1.yum remove docker docker-common container-selinux docker-selinux docker-engine

yum install -y yum-utils

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

yum makecache fast

yum list docker-ce.x86_64 --showduplicates |sort -r

yum install docker-ce.x86_64

### 修改默认存储路径

vim /usr/lib/systemd/system/docker.service

execstart=/usr/bin/dockerd -g /apps/docker/pmm (线上环境179的配置)

1. mkdir /home/docker（你想要docker存放image的目录）

2. systemctl stop docker

3. vi /usr/lib/systemd/system/docker.service

4. 添加 -g /home/docker (本地开发环境10.0.2.76的配置)

[unit]
description=docker application container engine
documentation=https://docs.docker.com
after=network.target docker.socket
requires=docker.socket

[service]
type=notify
execstart=/usr/bin/docker daemon -g /home/docker -h fd://
mountflags=slave
limitnofile=1048576
limitnproc=1048576
limitcore=infinity

[install]
wantedby=multi-user.target

### 启动

systemctl start docker

### 第二步:安装pmm服务端安装

# 配置加速镜像

1.curl -ssl https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://396e823a.m.daocloud.io //开启镜像加速,由于docker镜像被墙

[root@pgxl-71 ~]# curl -ssl https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://396e823a.m.daocloud.io
docker version >= 1.12
{"registry-mirrors": ["http://396e823a.m.daocloud.io"]}
success.
you need to restart docker to take effect: sudo systemctl restart docker

systemctl restart docker // docker重启

# 添加pmm-server镜像

docker pull percona/pmm-server:latest

# 添加数据容器

2.create a pmm data container //数据目录
$ docker create \
-v /opt/prometheus/data \
-v /opt/consul-data \
-v /var/lib/mysql \
-v /var/lib/grafana \
--name pmm-data \
percona/pmm-server:1.1.3 /bin/true

# 启动pmm-server容器
3.create and run the pmm server container //创建pmm server
$ docker run -d \
-p 80:80 \
--volumes-from pmm-data \
--name pmm-server \
-e server_user=admin \
-e server_password=password \
--restart always \
--init \
percona/pmm-server:1.1.3

### 第三步:安装pmm客户端安装
参考:https://www.percona.com/doc/percona-monitoring-and-management/deploy/client/yum.html#install-client-yum
1.yum install http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm
yum install pmm-client

[root@pgxl-71 ~]# pmm-admin --help
usage:
pmm-admin [flags]
pmm-admin [command]

available commands:
config configure pmm client.
add add service to monitoring.
remove remove service from monitoring.
list list monitoring services for this system.
info display pmm client information (works offline).
check-network check network connectivity between client and server.
ping check if pmm server is alive.
start start monitoring service.
stop stop monitoring service.
restart restart monitoring service.
show-passwords show pmm client password information (works offline).
purge purge metrics data on pmm server.
repair repair installation.
uninstall removes all monitoring services with the best effort.

flags:
-c, --config-file string pmm config file (default "/usr/local/percona/pmm-client/pmm.yml")
-v, --version show version

use "pmm-admin [command] --help" for more information about a command.

2.添加mongodb监控服务,自动会添加linux相关监控
##### 客户端配置
pmm-admin config --server 10.0.0.148 --server-user admin --server-password password --client-name hostname //

##### mongo服务器配置
pmm-admin add mongodb --cluster cluster1 --uri mongodb://root:123456@localhost:27017/admin
//cluster1 为自定义集群名
//--uri mongodb://root:123456@localhost:27017/admin 为monogo链地址

3.添加mysql监控服务,自动会添加linux相关监控
pmm-admin config --server 101.0.0.10 --server-user admin --server-password password --client-name hostname

以上3,4操作都会写入配置文件 /usr/local/percona/pmm-client/pmm.yml
pmm-admin 已经封装对prometheus修改

pmm-admin add mysql --user root --socket /apps/dbdat/mysql-5.7.17/mysql.sock --password 123456 mysql143

4.添加redis监控服务(生产线已不使用该方式)

wget https://github.com/oliver006/redis_exporter/releases/download/v0.11/redis_exporter-v0.11.linux-amd64.tar.gz
tar -zxvf redis_exporter-v0.11.linux-amd64.tar.gz

[root@pgxl-76 tmp]# ./redis_exporter --help
usage of ./redis_exporter:
-check-keys string
comma separated list of keys to export value and length/size
-debug
output verbose debug information
-log-format string
log format, valid options are txt and json (default "txt")
-namespace string
namespace for metrics (default "redis")
-redis.addr string
address of one or more redis nodes, separated by separator (default "redis://localhost:6379")
-redis.alias string
redis instance alias for one or more redis nodes, separated by separator
-redis.password string
password for one or more redis nodes, separated by separator
-separator string
separator used to split redis.addr, redis.password and redis.alias into several elements. (default ",")
-version
show version information and exit
-web.listen-address string
address to listen on for web interface and telemetry. (default ":9121")
-web.telemetry-path string
path under which to expose metrics. (default "/metrics")

启动客户端 ./redis_exporter -redis.addr redis://localhost:6379

redis_exporter 由于没有集成到pmm服务,所以需要修改prometheus,登入pmm服务端
[root@pgxl-76 tmp]# docker exec -it pmm-server /bin/bash
[root@a5914a0f9617 opt]# vim /etc/prometheus.yml //添加以下
- job_name: redis_exporter
static_configs:
- targets: ['10.0.2.76:9121']

5添加linux监控

pmm-admin config --server 10.0.5.179 --server-user pmm --server-password xxxxxxx --client-name pgxl182
pmm-admin add linux:metrics

###邮箱报警添加
进入docker
docker exec -it pmm-server /bin/bash

编缉grafana.ini
vim /etc/grafana/grafana.ini

[smtp]
enabled = true
host = smtp.healthmall.cn:25
user = liuqian@healthmall.cn
password = 123456
from_address = liuqian@healthmall.cn
from_name = grafana

### 钉钉报警配置

http://docs.grafana.org/alerting/notifications/

在钉钉上创作一个内部群，并添加webhook机器人。

dingding/dingtalk
instructions in chinese.

in dingtalk pc client:

click “more” icon on left bottom of the panel.

click “robot manage” item in the pop menu, there will be a new panel call “robot manage”.

in the “robot manage” panel, select “customised: customised robot with webhook”.

in the next new panel named “robot detail”, click “add” button.

in “add robot” panel, input a nickname for the robot and select a “message group” which the robot will join in. click “next”.

there will be a webhook url in the panel, looks like this: https://oapi.dingtalk.com/robot/send?access_token=xxxxxxxxx. copy this url to the grafana dingtalk setting page and then click “finish”.

dingtalk supports the following “message type”: text, link and markdown. only the text message type is supported.

升级
docker pull percona/pmm-server:latest
docker stop pmm-server && docker rm pmm-server
docker run -d -p 80:80 -p 9090:9090 --volumes-from pmm-data --name pmm-server -e server_user=pmm -e server_password=ngiisi0q4g9gfqwz89folkjsi --restart always --init percona/pmm-server:latest
