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()

import com.joshdholtz.sentry.Sentry;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

Sentry.init(this, “http://10.0.0.180”, “http://340137fc1dc6443e99d9d02b8f1638d0:cfd6587578e742948b60d72442fb4ac8@10.0.0.180/6”);
Sentry.captureMessage(“OMG this works woooo”);

int a = 1 / 0;
}
