Graphite简介
Graphite是一个Python编写的企业级开源监控工具，采用django框架，用来收集服务器所有的即时状态，用户请求信息，Memcached命中率,RabbitMQ消息服务器的状态，操作系统的负载状态。Graphite服务器大约每分钟需要有4800次的跟新操作，它采用简单的文本协议和绘图功能，可以方便的使用在任何操作系统上。Graphite 自己本身并不收集具体的数据，这些数据收集的具体工作通常由第三方工具或插件完成（如 Ganglia, collectd, statsd, Collectl 等)。
简单来说，Graphite主要做两件事情：
- 实时监控第三方工具传来的数据
- 根据数据绘制图形
Graphite包含3个组件，carbon，whisper，graphite webapp其中：
- carbon - 用于监控数据的 Twisted 守护进程
- whisper - 用于存放和操作数据的库
- graphite webapp - 用于绘制图形的Django webapp
关于Graphite的详细官方文档可以参考Graphite Documentation。
Graphite安装
我安装的环境是CentOS 7、python 2.7.5
1、修改yum源配置：
yum install wget mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup cd /etc/yum.repos.d/ wget http://mirrors.163.com/.help/CentOS6-Base-163.repo yum makecache yum -y update
2、安装pip、carbon 和whisper
yum -y install epel-release #安装epel扩展源pip才能安装 yum -y install python-pip yum -y install python-devel yum -y install gcc
yum -y install unzip pip install carbon pip install whisper
3、安装graphite-web
yum -y install libffi-devel zlib-devel openssl-devel install uwsgi-plugin-python pip install graphite-web
pip uninstall django
pip install django==1.8
4、修改配置文件
cd /opt/graphite/conf/ ls #查看所有文件，拷贝去除example cp aggregation-rules.conf.example aggregation-rules.conf cp blacklist.conf.example blacklist.conf cp carbon.amqp.conf.example carbon.amqp.conf cp carbon.conf.example carbon.conf cp dashboard.conf.example dashboard.conf cp graphite.wsgi.example graphite.wsgi cp graphTemplates.conf.example graphTemplates.conf cp relay-rules.conf.example relay-rules.conf cp rewrite-rules.conf.example rewrite-rules.conf cp storage-aggregation.conf.example storage-aggregation.conf cp storage-schemas.conf.example storage-schemas.conf cp whitelist.conf.example whitelist.conf cd /opt/graphite/webapp/graphite cp local_settings.py.example local_settings.py cd ../
mv content static vi uwsgi.ini
拷贝如下代码进去，保存退出
[uwsgi] # Django-related settings socket = :8000 buffer-size = 40000 plugins=python # the base directory (full path) chdir = /opt/graphite/webapp # Django s wsgi file module = graphite.wsgi # process-related settings # master master = true # maximum number of worker processes processes = 1 # ... with appropriate permissions - may be needed # chmod-socket = 664 # clear environment on exit vacuum = true
5、安装uwsgi和nginx
yum -y install uwsgi cd /home/admin/ wget http://nginx.org/download/nginx-1.4.7.tar.gz tar zxvf nginx-1.4.7.tar.gz cd nginx-1.4.7 ./configure --with-openssl=/usr/include/openssl vi objs/Makefile #把第3行的“ -Werror ” 删除，保存，关闭 make make install vi /usr/local/nginx/conf/nginx.conf
拷贝如下代码进去，保存退出
user root;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.*;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 8001;
server_name localhost;
charset utf-8;
#access_log logs/host.access.log main;
location / {
include uwsgi_params;
uwsgi_pass 127.0.0.1:8000;
uwsgi_read_timeout 2;
}
location /static {
root /opt/graphite/webapp;
}
}
}6、在网站上找到项目，创建manage.py，好进行数据库的操作，和测试显示项目中的问题
cd /opt/graphite/webapp/
vi manage.py 拷贝如下代码进去，保存退出
1 #!/usr/bin/env python 2 import os 3 import sys 4 5 6 if __name__ == "__main__": 7 os.environ.setdefault("DJANGO_SETTINGS_MODULE", "graphite.settings") 8 9 from django.core.management import execute_from_command_line 10 11 execute_from_command_line(sys.argv)
pip install scandir python manage.py migrate vi /opt/graphite/webapp/graphite/local_settings.py #取消SECRET_KEY、TIME_ZONE注释，并且修改值： SECRET_KEY = '@2o8&38gcsb(p*o*dy(fmh!_3-30a1qwq$sadb+6vk243%wj0#' TIME_ZONE = 'Asia/Shanghai' #保存退出
7、通过manage.py shell修改网站登录的用户名和密码
python manage.py shell >>> from django.contrib.auth.models import User >>> user_list=[x for x in User.objects.all()] >>> print user_list #如果user_list不为空 >>>user=user_list[0] >>>user.username='admin' >>>user.set_password='123123' >>>user.save() #如果user_list为空 >>>quit() python manage.py createsuperuser #根据提示创建你的用户 Username (leave blank to use 'root'): admin Email address: 123123@qq.com Password: #输入后不会显示，我输的123123 Password (again): #输入后不会显示
8、启动carbon，carbon会在默认的2003端口接收数据。
python /opt/graphite/bin/carbon-cache.py start uwsgi --ini /opt/graphite/webapp/uwsgi.ini #再新建一个窗口，启动nginx，或者让uwsgi后台运行，建议测试的时候新建窗口，错误好捕获。启动nginx之前，先关闭防火墙或者开启8001端口。我做测试，就关闭防火墙了。 systemctl disable firewalld #停用防火墙 systemctl stop firewalld #禁止防火墙 /usr/local/nginx/sbin/nginx #启动nginx /usr/local/nginx/sbin/nginx -s reload #重启nginx
9、浏览网址http://127.0.0.1:8001，出现如下画面，安装成功，如果失败，注意查看nginx的错误日志和uwsgi的提示
