使用Sentry集中化日志管理
在调试程序中，通过日志分期来排查BUG是一个重要手段，它可以说是程序调试的利器。
关于日志管理
随着应用组件变多，那么各coder对输出日志五花八门，有写入stdout，有写stderr, 有写到syslog，也有写到xxx.log的。那么这将导致平台应用日志分布在各个地方，无法统一管理。
为什么使用Sentry
Sentry是一个集中式日志管理系统。它具备以下优点：
- 多项目，多用户
- 界面友好
- 可以配置异常出发规则，例如发送邮件
- 支持主流语言接口
安装
参考 https://docs.getsentry.com/on-premise/server/installation/
Requirements
- Linux Server
- PostgreSQL
- redis-server
- Python 2/3
- Nginx
步骤
安装依赖包
sudo apt-get install python-setuptools python-pip python-dev libxslt1-dev libxml2-dev libz-dev libffi-dev libssl-dev libpq-dev libyaml-dev
安装Sentry
pip install -U sentry==8.0.0rc2
配置
vim sentry.conf.py
DATABASES = { 'default': { 'ENGINE': 'sentry.db.postgres', 'NAME': 'sentry', 'USER': 'postgres', 'PASSWORD': '123456', 'HOST': 'localhost', 'PORT': '5432', } }
EMAIL_HOST = 'smtp.exmail.qq.com' EMAIL_HOST_PASSWORD = 'HE*******' EMAIL_HOST_USER = 'hewx@doordu.com' EMAIL_PORT = 25 EMAIL_USE_TLS = False
设置配置文件路径到环境变量
export SENTRY_CONF=/home/hewx/workbench/sentry
初始化数据库
sentry update
配置Web Server
sudo apt-get install nginx-full sudo vim /etc/nginx/sites-enabled/default
location / { proxy_pass http://localhost:9000; proxy_redirect off;
proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; }
启动
启动Wokers
sentry celery worker -B
启动Web服务
sentry start
实例
PHP
使用浏览器访问sentry，并创建一个项目
参考PHP使用指令http://10.0.0.180/sentry/45183e54fa36/settings/install/php/
<?php
require_once "vendor/autoload.php";
$client = new Raven_Client('http://5d68caa5e36c4eaa8f7c0601a521fab6:b5917e01d45f4656ab2d943264b90377@10.0.0.180/3');
$error_handler = new Raven_ErrorHandler($client); $error_handler->registerExceptionHandler(); $error_handler->registerErrorHandler(); $error_handler->registerShutdownFunction();
$client->captureMessage("这里发生了一个错误");
$i = 1 / 0;
?>
Python
pip install raven
from raven import Client
client = Client('http://f1ba62aa87cb4fc1a36d9e4f96017e99:96f5feef13dc4d45825e73548cd5b784@10.0.0.180/4')
try: 1 / 0 except ZeroDivisionError: client.captureException()
JavaScript

int a = 1 / 0; } ......
