Sentry<\/a> is a real time event logging and aggregation platform. It allows to aggregate all events of your project in one place. It may be handy to get all logging messages and to have a possibility to track what’s going on with your application. You could use Sentry\u00a0with node.js, PHP, Go, Python, Java and some other languages\/applications.\u00a0Full list of available clients<\/a>.<\/p>\n

So let’s get started. First problem you encounter while installing Sentry on Centos 6.5. is Python version. It’s written with use of Django and requires \u00a0Python 2.7, while Centos shipped with version 2.6. \u00a0There are various ways to get Python on Centos, for instance, to compile it from the sources, which is obviously not the best way. \u00a0We will use pyenv<\/a>,\u00a0version management system for Python. Detailed description on how to install Python 2.7 on Centos 6.5<\/a> can be found in our previous post.<\/p>\n

One important note, it would be much better to create some system account and to use it for all following actions. Let’s call it sentry:<\/p>\n

adduser sentry ; su \u00a0- sentry<\/code><\/p>\n

Once Python 2.7 is installed, install Sentry:<\/p>\n

pip2.7 install sentry<\/code><\/p>\n

We are going to use MySQL so we need one more package for Sentry:<\/p>\n

pip2.7 install sentry[mysql]<\/code><\/p>\n

(If you encounter and issue make sure you have mysql-devel<\/em> installed).<\/p>\n

Init Sentry config:<\/p>\n

sentry init<\/code><\/p>\n

Modify the config to file with your real values for host, databases, etc:<\/p>\n

from sentry.conf.server import *\nimport os.path\nCONF_ROOT = os.path.dirname(__file__)\nDATABASES = {\n 'default': {\n 'ENGINE': 'django.db.backends.mysql',\n 'NAME': 'sentry',\n 'USER': 'sentry',\n 'PASSWORD': 'strongpasswprd',\n 'HOST': 'localhost',\n 'PORT': '3306',\n }\n}\nCELERY_ALWAYS_EAGER = False\nBROKER_URL = 'redis:\/\/localhost:6379'\nSENTRY_BUFFER = 'sentry.buffer.redis.RedisBuffer'\nSENTRY_REDIS_OPTIONS = {\n 'hosts': {\n 0: {\n 'host': '127.0.0.1',\n 'port': 6379,\n }\n }\n}\nUSE_X_FORWARDED_HOST = True\nSENTRY_WEB_HOST = '127.0.0.1'\nSENTRY_WEB_PORT = 9028\nSENTRY_WEB_OPTIONS = {\n 'secure_scheme_headers': {'X-FORWARDED-PROTO': 'https'},\n}\nEMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'\nEMAIL_HOST = 'sentry.example.com'\nEMAIL_HOST_PASSWORD = ''\nEMAIL_HOST_USER = ''\nEMAIL_PORT = 25\nEMAIL_USE_TLS = False\nSERVER_EMAIL = 'sentry@example.com'\nSECRET_KEY = '7mdR5dLYdS5dS5F4sfFswsEUfH8s45sdgtfisdqdYVgdIsbdduv6g7gggsgJFgXg=='\nTWITTER_CONSUMER_KEY = ''\nTWITTER_CONSUMER_SECRET = ''\nFACEBOOK_APP_ID = ''\nFACEBOOK_API_SECRET = ''\nGOOGLE_OAUTH2_CLIENT_ID = ''\nGOOGLE_OAUTH2_CLIENT_SECRET = ''\nGITHUB_APP_ID = ''\nGITHUB_API_SECRET = ''\nTRELLO_API_KEY = ''\nTRELLO_API_SECRET = ''\nBITBUCKET_CONSUMER_KEY = ''\nBITBUCKET_CONSUMER_SECRET = ''\nINSTALLED_APPS += ('nagios_sentry', )\n<\/pre>\n
If you don’t have Redis installed, install it and proceed:<\/p>\n
yum install redis<\/code><\/p>\n
Create MySQL database for Sentry:<\/p>\n
CREATE DATABASE sentry_database\u00a0CHARACTER SET utf8;\nGRANT ALL PRIVILEGES ON sentry_database\u00a0.* TO 'user'@'%' identified by 'passwd';\n<\/pre>\n
Run the migrations:<\/p>\n
sentry upgrade<\/code><\/p>\n
Now create admin user:<\/p>\n
sentry createsuperuser\nsetry repair --owner=<username>\n<\/pre>\n
We are ready to start Sentry.<\/p>\n
sentry start<\/code><\/p>\n
Now you can log in and start using Sentry.<\/p>\n
Few notes about performance and monitoring.<\/p>\n
