Sentry 由python开发，django为框架的跨平台多语言/框架的日志聚合平台，功能十分强悍。截至目前最新版本是8.22.0
$ python -c "import sentry; print(sentry.__version__)"
8.22.0
下面以Centos7平台下分三部处理sentry:
- 安装
- 配置
- 使用
一.安装
首先安装sentry所依赖的PostgreSQL数据库。
# 在系统中添加官网提供的对应版本的Yum仓库, 如下是9.6版本
sudo yum install https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-6-x86_64/pgdg-centos96-9.6-3.noarch.rpm
# 然后安装PostgreSQL数据库
yum update # 这一步可省略
yum -y install vim python-setuptools python-dev libxslt1-dev gcc libffi-dev libjpeg-dev libxml2-dev libxslt-dev libyaml-dev libpq-dev
yum install postgresql96-server postgresql96-contrib postgresql-devel
接下来配置PostgreSQL依赖的环境，然后启动数据库
sudo mkdir -p /data/pgsql # 数据库物理文件的存放目录
sudo chown postgres:postgres /data/pgsql # 所属组/成员
sudo su - postgres
cp /etc/skel/.bash* /var/lib/pgsql
编辑 /var/lib/pgsql/.bashrc文件，设置PGDATE环境变量并添加pgsql的bin路径到PATH变量。
export PGDATA=/data/pgsql
export PATH=/usr/pgsql-9.6/bin:$PATH
使环境生效：
source .bashrc
然后初始化数据库并启动：
$ [postgres@me ~]$ initdb # 初始化
$ [postgres@me ~]$ ls /data/pgsql/
..
$ [postgres@me ~]$ pg_ctl start
查看 tail /data/pgsql/pg_log/postgresql-*.log 日志信息:
接下来为Sentry提供PostgreSQL数据库信息：
[postgres@me ~]$ psql
psql (9.6.1)
Type "help" for help.
postgres=# \l
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
-----------+----------+----------+-------------+-------------+-----------------------
postgres | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
template0 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres +
| | | | | postgres=CTc/postgres
template1 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres +
| | | | | postgres=CTc/postgres
(3 rows)
postgres=# CREATE USER sentry WITH PASSWORD '*****';
CREATE ROLE
postgres=# CREATE DATABASE sentry OWNER sentry;
CREATE DATABASE
postgres=# GRANT ALL PRIVILEGES ON DATABASE sentry to sentry;
GRANT
ALTER USER sentry WITH SUPERUSER;
ALTER ROLE
postgres=# \q
这些依赖安装和配置成功后就开始安装sentry：
$ sudo pip install sentry
...
Error: pg_config executable not found
结果报错了， pg_config executable not found, 在这里pg_config executable not found有解决方案，原因就是pg_config可执行文件不在PATH环境变量里， pg_config就是上面安装PostgreSQL的文件。
$ which pg_config
... 没有
在.bashrc下添加PATH：
export PATH=$PATH:/usr/pgsql-9.6/bin/
然后激活环境： source ~/.bashrc
接下来安装：
pip install psycopg2 sentry
# 查看是否安装成功
python -c "import sentry;print(sentry.__version__)"
安装并启动redis
yum -y install redis
/usr/bin/redis-server /etc/redis.conf
二. 配置
首先初始化sentry生成配置文件：
[root@me ~]sentry init /etc/sentry
[root@me ~]cd /etc/sentry
[root@me /etc/sentry]$ tree
.
├── config.yml
└── sentry.conf.py
其中在sentry.conf.py下配置 PostgreSQL DATABASES 和 BROKER_URL：
DATABASES = {
'default': {
'ENGINE': 'sentry.db.postgres',
'NAME': 'sentry',
'USER': 'app',
'PASSWORD': '*****',
'HOST': 'localhost',
'PORT': '5432',
'AUTOCOMMIT': True,
'ATOMIC_REQUESTS': False,
}
}
BROKER_URL = "redis://:password@localhost:6379/2"
config.yaml 文件配置如下：
# While a lot of configuration in Sentry can be changed via the UI, for all
# new-style config (as of 8.0) you can also declare values here in this file
# to enforce defaults or to ensure they cannot be changed via the UI. For more
# information see the Sentry documentation.
###############
# Mail Server #
###############
mail.backend: 'smtp' # Use dummy if you want to disable email entirely
mail.host: 'smtp.263.net'
mail.port: 465
mail.username: 'support@xxx.cn'
mail.password: '****'
mail.use-tls: true
# The email address to send on behalf of
mail.from: 'support@***.cn'
# If you'd like to configure email replies, enable this.
# mail.enable-replies: false
# When email-replies are enabled, this value is used in the Reply-To header
# mail.reply-hostname: ''
# If you're using mailgun for inbound mail, set your API key and configure a
# route to forward to /api/hooks/mailgun/inbound/
# mail.mailgun-api-key: ''
###################
# System Settings #
###################
# If this file ever becomes compromised, it's important to regenerate your a new key
# Changing this value will result in all current sessions being invalidated.
# A new key can be generated with `$ sentry config generate-secret-key`
system.secret-key: '(80z$b)5u)oxq^kkzr^1r5%6^_4y3hrv0+!nlp!q1w+^fb#yux'
# The ``redis.clusters`` setting is used, unsurprisingly, to configure Redis
# clusters. These clusters can be then referred to by name when configuring
# backends such as the cache, digests, or TSDB backend.
redis.clusters:
default:
hosts:
0:
host: 127.0.0.1
port: 6379
password: '*****'
这里注意，如果邮件使用SSL, 则需要 SMTP SSL email backend for Django
pip install django-smtp-ssl
sentry数据库初始化，然后将sentry的用户权限改为普通
SENTRY_CONF=/etc/sentry sentry upgrade
psql
ALTER USER sentry WITH NOSUPERUSER;
ALTER ROLE
postgres=# \q
然后配置 supervisor文件：
[root@me ~]# vim /etc/supervisord.d/sentry.ini
[program:sentry-web]
environment=SENTRY_CONF="/etc/sentry"
command=sentry run web
autostart=true
autorestart=true
user=sentry
stdout_logfile=/home/sentry/logs/web.log
stderr_logfile=/home/sentry/logs/web.log
[program:sentry-worker]
environment=SENTRY_CONF="/etc/sentry"
command=sentry run worker
autostart=true
autorestart=true
user=sentry
stdout_logfile=/home/sentry/logs/worker.log
stderr_logfile=/home/sentry/logs/worker.log
[program:sentry-cron]
environment=SENTRY_CONF="/etc/sentry"
command=sentry run cron
autostart=true
autorestart=true
user=sentry
stdout_logfile=/home/sentry/logs/cron.log
stderr_logfile=/home/sentry/logs/cron.log
生效并启动配置：
supervisord -c /etc/supervisor.conf #启动supervisord
supervisorctl -c /etc/supervisor.conf reread # 读取配置
supervisorctl -c /etc/supervisor.conf update # 启动
supervisorctl -c /etc/supervisor.conf status # 查看
supervisorctl -c /etc/supervisor.conf restart all #重启所有任务
这里总结下supervisord常见的问题和解决方案：
1. 当 supervisord 启动异常时，可 `supervisord -n` 前台启动查看详细信息
2. 一般supervisor异常分两种，配置不对或权限的问题。
3. 善用日志信息，首先要在supervisord.conf设置的日志下查看详情。
配置计划任务，清除历史数据
$ crontab -e
0 3 * * * sentry cleanup --days=30
