docker graphite 部署

pennate

　　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
