sentry¶

配置¶

安装¶

安装sentry前，需要先安装mysql 和redis. sentry可以用pip 安装:

> pip install sentry

启动¶

先启动mysql:

> /etc/init.d/mysqld restart

再创建一份sentry新配置文件:

> sentry init <配置文件名>

修改配置文件，配置database信息，如下:

DATABASES = {
        'default': {
            # You can swap out the engine for MySQL easily by changing this value
            # to ``django.db.backends.mysql`` or to PostgreSQL with
            # ``django.db.backends.postgresql_psycopg2``

            # If you change this, you'll also need to install the appropriate python
            # package: psycopg2 (Postgres) or mysql-python

            'ENGINE': 'django.db.backends.mysql',
            'NAME': '数据库名',
            'USER': '账号名',
            'PASSWORD': 'msyql密码',
            'HOST': 'localhost',
            'PORT': '3307',
            }
}

接下来需要先搞好mysql:

# 创建数据库
mysql> create database 数据库

# 创建账号
mysql> create user 用户@主机 IDENTIFIED by '密码'

# 给这个用户授权

mysql> grant all on sentry.* to user@'localhost'

接下来搞好redis, sentry 内部用redis是用来做缓存的，提高性能. Redis启动略过，sentry里redis配置如下:

SENTRY_BUFFER = 'sentry.buffer.redis.RedisBuffer'
SENTRY_REDIS_OPTIONS = {
    'hosts': {
        0: {
            'host': '127.0.0.1',
            'port': 6379,
        }
    }
}

接下来在启动sentry 之前，可以选择两种worker处理方式:

一种是celery队列异步处理。这种方式除了启动sentry web 外，还要启动多个celery worker进程，注意，这些celery worker 进程可能会crash掉，所以需要用supervisor 来监控

另一种是不用celery队列，来了一个event事件，同步处理，性能可能差些。但是不用起celery worker进程了，不用担心celery crash 掉

如果是用celery队列，那么先启动celery worker:

# 起3个worker
> sentry --config=./sentry.settings.py celery worker -B &
> sentry --config=./sentry.settings.py celery worker -B &
> sentry --config=./sentry.settings.py celery worker -B &

接下来就是启动main server:

> sentry --config=./sentry.settings.py start

然后创建superuser:

> sentry --config=senry.settings.py createsuperuser

整个过程完成，现在可以用web登陆sentry了

报警邮件¶

configure as this:

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.163.com'
EMAIL_HOST_PASSWORD = 'yourpassword'
EMAIL_HOST_USER = 'service@163.com'
EMAIL_PORT = your_port
EMAIL_USE_TLS = True
SERVER_EMAIL = 'service@163.com'

Cannot receive email notifytion After configure email:

Enter email test web(http://localhost:9000/manage/status/mail/) and type [send a test email]. If it report STARTTLS extension not supported by server , you must set EMAIL_USE_TLS = False in your sentry configure

问题¶

启动时报错: Transaction managed block ended with pending COMMIT/ROLLBACK:

$> sentry start

Performing upgrade before service startup...

      > djcelery:0001_initial
      TransactionManagementError: Transaction managed block ended with pending COMMIT/ROLLBACK

这是因为权限问题, sentry配置文件里的user, 没有足够的权限操作sentry数据库, 用超级账号调用:

mysql> grant all on sentry.* to user@'localhost'

sentry After start sentry web, cannot mark event to reslove:

This maybe cause by SENTRY_URL_PREFIX configure. If your add resversal proxy in front of sentry, you must set SENTRY_URL_PREFIX to the IP of resversal proxy
