在調試程序中，通過日志分期來排查BUG是一個重要手段，它可以說是程序調試的利器。
關於日志管理
隨着應用組件變多，那么各coder對輸出日志五花八門，有寫入stdout，有寫stderr, 有寫到syslog，也有寫到xxx.log的。那么這將導致平台應用日志分布在各個地方，無法統一管理。
為什么使用Sentry
Sentry是一個集中式日志管理系統。它具備以下優點：
- 多項目，多用戶
- 界面友好
- 可以配置異常出發規則，例如發送郵件
- 支持主流語言接口
安裝
參考
https://docs.getsentry.com/on-premise/server/installation/
Requirements
- Linux Server
- PostgreSQL
- redis-server
- Python 2/3
- Nginx
步驟
安裝依賴包
sudo apt-get install python-setuptools python-pip python-dev libxslt1-dev libxml2-dev libz-dev libffi-dev libssl-dev libpq-dev libyaml-dev
安裝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
設置配置文件路徑到環境變量
export SENTRY_CONF=/home/hewx/workbench/sentry
初始化數據庫
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; }
啟動
啟動Wokers
sentry celery worker -B
啟動Web服務
sentry start
實例
PHP
使用瀏覽器訪問sentry，並創建一個項目
參考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("這里發生了一個錯誤"); $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()
