docker 部署
centos命令：
关闭防火墙
systemctl stop firewalld.service
查看网络
ip addr
docker run -d -p 9090:9090 \
-v /root/prometheus.yml:/etc/prometheus/prometheus.yml \
--name prometheus \
--net=host \

grafana部署
## 普通启动，挂载数据盘
docker run -d --name grafana -p 3000:3000 -v /data/grafana:/var/lib/grafana grafana/grafana
## 复制出配置文件
docker cp grafan:/etc/grafana/grafana.ini /data/grafana-data/etc/
修改http_port = 80
docker rm 旧的容器
docker run --user root -d --name grafana -p 3000:80 -v /data/grafana-data/etc:/etc/grafana/ -v /data/grafana-data/grafana:/var/lib/grafana grafana/grafana
部署consul
docker pull consul
mkdir -p /data/consul/{conf,data}
docker run --name consul -p 8500:8500 -v /data/consul/conf/:/consul/conf/ -v /data/consul/data/:/consul/data/ -d consul
docker run --name consul -d -p 8500:8500 -p 8300:8300 -p 8301:8301 -p 8302:8302 -p 8600:8600 consul:1.2.2 agent -server -bootstrap-expect 2 -ui -bind=0.0.0.0 -client=0.0.0.0
在CentOS 7下使用类似nginx之类的web server，启动docker时有时会报以下错误：
docker0: iptables: No chain/target/match by that name.
解决方法：
service docker restart
重启docker后:
iptables -L
可以看到iptables里面多出了Chain Docker的选项。
经验为：在启动firewalld之后，iptables被激活，此时没有docker chain，重启docker后被加入到iptable里面。
注册服务到consul：
curl -X PUT -d '{"id": "redis-xxx","name": "redis-xxx","address": "127.0.0.1","port": 9121,"tags": ["test"],"checks": [{"http": "http://127.0.0.1:9121/","interval": "5s"}]}' http://127.0.0.1:8500/v1/agent/service/register
curl -X PUT -d '{"id": "exporter","name": "exporter","address": "192.168.2.133","port": 31247,"tags": ["test"],"checks": [{"http": "http://192.168.2.133:31247/","interval": "5s"}]}' http://119.3.242.247:32011/v1/agent/service/register
删除
curl -X PUT http://119.3.242.247:32011/v1/agent/service/deregister/redis-xxx
