基础篇-Docker安装Prometheus

Docker安装Prometheus

详细操作

• 安装docker服务

yum -y install gcc gcc-c++ yum-utils
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum -y install docker-ce docker-ce-cli containerd.io

systemctl start docker
systemctl status docker
docker --version

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

• 下载相关镜像

docker pull prom/node-exporter
docker pull prom/mysqld-exporter
docker pull prom/alertmanager
docker pull oliver006/redis_exporter 
docker pull prom/prometheus
docker pull grafana/grafana

• 启动相关容器

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

docker run -d --name mysqld_exporter \
--restart=always -p 9104:9104 \
-e DATA_SOURCE_NAME="ucds:ucds@(192.168.27.52:3306)/"  \
prom/mysqld-exporter

#不带密码
docker run -d --name redis_exporter -p 9121:9121 oliver006/redis_exporter --redis.addr redis://192.168.27.44:27001
 
# 带密码
docker run -d --name redis_exporter -p 9121:9121 oliver006/redis_exporter --redis.addr redis://192.168.27.44:27001 --redis.password 'abc123'
