环境:阿里云CentOS7.9
docker部署
1、确定是CentOS7及以上版本
cat /etc/redhat-release
2、如有旧版本,需要先卸载旧版本
yum remove docker
3、yum安装gcc相关以及需要的软件包
yum -y install gcc gcc-c++ yum-utils
4、配置国内docker-ce的yum源(采用的是阿里云)
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
5、配置完yum源后可以切换到/etc/yum.repos.d/目录下,查看下是否存在docker-ce.repo,存在的话说明配置成功
6、更新yum软件包索引
yum makecache fast
7、安装docker
yum -y install docker-ce docker-ce-cli containerd.io
8、启动docker
systemctl start docker
systemctl status docker
9、查看docker版本
docker --version
Docker version 26.1.4, build 5650f9b
10、配置镜像加速器
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://cz1numin.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
11、docker info命令查看一下是否新增了阿里云的地址,确保配置成功
Prometheus部署
1、下载镜像包
docker pull prom/node-exporter
docker pull prom/mysqld-exporter
docker pull oliver006/redis_exporter
docker pull prom/prometheus
docker pull grafana/grafana
prom/node-exporter
:用于收集主机系统信息和指标的prom/mysqld-exporter
:用于收集数据库系统信息和指标的oliver006/redis_exporter
:用于收集redis信息和指标的grafana/grafana
:是一个用于可视化和分析监控指标的开源平台。prom/prometheus
:是一个开源的监控系统,用于收集和存储时间序列数据,并提供基于数据的查询、报警和可视化功能。
2、启动容器
2.1启动**
node-exporter
**
docker run -d --name node-exporter \
--restart=always -p 9100:9100 \
-v /proc:/host/proc:ro \
-v /sys:/host/sys:ro \
-v /:/rootfs:ro prom/node-exporter
访问地址:http://47.119.27.111:9100/metrics
2.2启动 **
mysqld-exporter
**
docker run -d --name mysqld_exporter \
--restart=always -p 9104:9104 \
-e DATA_SOURCE_NAME="root:Password123@(192.168.0.230:3306)/" \
prom/mysqld-exporter
访问地址:http://47.119.27.111:9104/metrics
2.3启动 **
redis_exporter
**
#不带密码
docker run -d --name redis_exporter -p 9121:9121 oliver006/redis_exporter --redis.addr redis://192.168.0.230:6379
# 绑定集群中一个redis实例就可以了
# 带密码
docker run -d --name redis_exporter -p 9121:9121 oliver006/redis_exporter --redis.addr redis://192.168.0.230:6379 --redis.password '123123'
访问地址:http://47.119.27.111:9121/metrics
2.4查看容器IP
查看当前运行的网络列表
docker network ls
NETWORK ID NAME DRIVER SCOPE
16dab27fe490 bridge bridge local
05a7e6db54e6 host host local
f2da59c2d4f9 none null local
查看指定网络中的容器和其IP地址
docker network inspect <网络ID或网络名称>

"MacAddress": "02:42:ac:11:00:03",
"IPv4Address": "172.17.0.3/16",
"IPv6Address": ""

2.5启动Prometheus
新建目录prometheus,编辑配置文件prometheus.yml
mkdir /opt/prometheus
cd /opt/prometheus/
vim prometheus.yml
global:
scrape_interval: 60s
evaluation_interval: 60s
scrape_configs:
- job_name: prometheus
static_configs:
- targets: ['localhost:9090']
labels:
instance: prometheus
- job_name: node
static_configs:
- targets: ['172.17.0.2:9100']
labels:
instance: node-exporter
- job_name: redis
static_configs:
- targets: ['172.17.0.4:9121']
labels:
instance: redis_exporter
- job_name: mysqld
static_configs:
- targets: ['172.17.0.3:9104']
labels:
instance: mysql-exporter
启动(注意:宿主机的路径必须是绝对路径:
/opt/prometheus/prometheus.yml
,否则会报错)
docker run -d --name prometheus --restart=always -p 9090:9090 -v /opt/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus
访问地址:http://47.119.27.111:9090/graph
访问targets地址:http://47.119.27.111:9090/targets
2.6启动grafana
新建空文件夹grafana-storage,用来存储数据
mkdir /opt/grafana-storage
添加权限
chmod 777 -R /opt/grafana-storage
启动
docker run -d --name grafana --restart=always \
-p 3000:3000 --name=grafana \
-v /opt/grafana-storage:/var/lib/grafana grafana/grafana
访问地址:http://47.119.27.111:3000/login
配置Grafana
默认登录:admin/admin
设置----》Data sources----》Add data source
选择Prometheus
Name:Prometheus
URL【Prometheus的ip(docker容器私网ip)+端口】:http://172.17.0.5:9090
