docker graphite 部署
docker graphite 部署
docker graphite
一、获取graphite-centos docker image
sudo docker pull steeef/graphite-centos
(参见：https://registry.hub.docker.com/u/steeef/graphite-centos/）
二、运行一个graphite容器
docker run -d \ --name graphite \ -v /data/uxin/graphite:/var/lib/graphite/storage/whisper \ -p 8880:80 \ -p 2003:2003 \ -p 2004:2004 \ -p 7002:7002 \ steeef/graphite-centos
三、在容器中执行bash
1.进入graphite容器：
sudo docker exec -t -i graphite /bin/bash
2.修改graphite配置：
1）修改graphite显示时间：
TIME_ZONE = \'Asia/Shanghai\'
2）修改系统时区
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
3.为nginx的登录增加用户名和密码（见另一篇博文）
4.重新启动服务
将/etc/supervisor.conf中关于nginx的启动去掉，改为在/tmp/start.sh中启动nginx，并且nginx.conf配置ngingx的启动方式为daemon启动，需要将daemon off注释掉。
这样做的原因是使用supervisor来启动nginx会将CPU占用率位置在90%以上。
执行启动所有服务/tmp/start.sh
四、使用docker停止、重新启动容器
sudo docker stop graphite sudo docker restart graphite sudo docker top graphite
