Spring Boot实战之配置使用Sentry上报错误日志(一)

Spring Boot实战之配置使用Sentry上报错误日志(一)

本文介绍Sentry Server环境的安装与配置，本文基于Centos7进行测试

Sentry 是一款基于 Django实现的错误日志收集和聚合的平台，它是 Python 实现的，但是其日志监控功能却不局限于python，对诸如 Node.js, php,ruby, C#,java 等语言的项目都可以做到无缝集成，甚至可以用来对iOS, Android 移动客户端以及 Web前端异常进行跟踪。我们可以在程序中捕获异常，并发送到 Sentry服务端进行聚合统计、展示和报警。

一、安装mysql

1) 获取并安装mysql社区版本

wget http://repo.mysql.com//mysql57-community-release-el7-8.noarch.rpmrpm -ivh mysql57-community-release-el7-8.noarch.rpmyum install mysql-community-server

2) 启动mysql

service mysqld restart

3) 刚安装时，已经生成了root的初始密码，使用以下命令进行查看

grep 'temporary password' /var/log/mysqld.log2016-08-09T04:36:57.654274Z 1 [Note] A temporary password is generated for root@localhost: jDTcYtBnu4=v

4) 使用上面的密码进行登录

mysql -uroot -p

5) 将临时密码修改为自己的新密码

ALTER USER 'root'@'localhost' IDENTIFIED BY 'mypassword';

6) 新建数据库sentry，之后sentry的配置文件会用到

create database sentry;

二、安装epel源

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpmrpm -ivh epel-release-latest-7.noarch.rpm 

三、安装redis

yum -y install redis

 1) 启动redis

systemctl start redis.service

2) 其它基本命令(供参考)

#停止systemctl stop redis.service#重启systemctl restart redis.service#检查状态systemctl status redis.service#打开开机启动systemctl enable redis.service

四、python环境
本文测试环境为centos7,默认已经安装python 2.7.5版本。Python的版本要>= 2.7，如果系统的Python版本过低，需要升级python。

[root@sunt2 home]# python -V && pip -VPython 2.7.5-bash: pip: 未找到命令

1) 安装pip

wget https://bootstrap.pypa.io/get-pip.pypython get-pip.py

2) 安装virtualenv virtualenvwrapper

pip install virtualenv virtualenvwrapper

3) 修改~/.bashrc文件，设置环境变量，添加以下内容：

export WORKON_HOME=/var/sentryenvexport VIRTUALENVWRAPPER_PYTHON=/usr/bin/pythonexport VIRTUALENVWRAPPER_VIRTUALENV=/usr/bin/virtualenvsource /usr/bin/virtualenvwrapper.sh

4) 使环境变量生效

source ~/.bashrc

五、安装Sentry Server
1） 按顺序安装以下包

mkvirtualenv sentryyum install python-develyum install libffi-develyum install openssl-develeasy_install Cythonyum install libxslt-devel libxml2-develyum install postgresql-develpip install sentry[mysql]pip install sentryyum install mysql-develpip install sentry[mysql] --upgrade

2）启用virtualenv，进入Python环境

source /var/sentryenv/sentry/bin/activate

3）安装相关的Python库：

pip install redis hiredis nyduspip install redis hiredis nydus --upgradepip install geventpip install eventleteasy_install MySQL-python

4）初始化Sentry的配置文件，会在/var/sentryenv/sentry/etc下生成配置文件sentry.conf.py ：

mkdir -p /var/sentryenv/sentry/etc/var/sentryenv/sentry/bin/sentry  init /var/sentryenv/sentry/etc/

5）生成key

/var/sentryenv/sentry/bin/sentry config generate-secret-keyd5c=igv90h(r+zbtgd+ea=^%_fd!-x5b=fdyh4vv#%#i7_ll#k            #配置文件中使用

6）修改配置文件/var/sentryenv/sentry/etc/sentry.conf.py 如下

# This file is just Python, with a touch of Django which means# you can inherit and tweak settings to your hearts content.from sentry.conf.server import *import os.pathCONF_ROOT = os.path.dirname(__file__)DATABASES = {    'default': {        'ENGINE': 'django.db.backends.mysql',        'NAME': 'sentry',        'USER': 'root',        'PASSWORD': 'mypassword',        'HOST': 'localhost',        'PORT': '3306',        'AUTOCOMMIT': True,        'ATOMIC_REQUESTS': False,    }}SENTRY_USE_BIG_INTS = TrueSENTRY_SINGLE_ORGANIZATION = TrueDEBUG = FalseSENTRY_OPTIONS["redis.clusters"]={    'default':{        'hosts':{        0: {            'host': '127.0.0.1',            'port': 6379,        }     }   }}SENTRY_CACHE = 'sentry.cache.redis.RedisCache'BROKER_URL = 'redis://localhost:6379'SENTRY_RATELIMITER = 'sentry.ratelimits.redis.RedisRateLimiter'SENTRY_BUFFER = 'sentry.buffer.redis.RedisBuffer'SENTRY_QUOTAS = 'sentry.quotas.redis.RedisQuota'SENTRY_TSDB = 'sentry.tsdb.redis.RedisTSDB'SENTRY_DIGESTS = 'sentry.digests.backends.redis.RedisBackend'SENTRY_FILESTORE = 'django.core.files.storage.FileSystemStorage'SENTRY_FILESTORE_OPTIONS = {    'location': '/tmp/sentry-files',}SENTRY_OPTIONS['system.url-prefix']='http://192.168.1.112:9000'SENTRY_WEB_HOST = '0.0.0.0'SENTRY_WEB_PORT = 9000SENTRY_WEB_OPTIONS = {    'daemon':True    # 'workers': 3,  # the number of web workers    # 'protocol': 'uwsgi',  # Enable uwsgi protocol instead of http}SENTRY_OPTIONS['mail.mailgun-api-key']=''SENTRY_OPTIONS['system.secret-key']='d5c=igv90h(r+zbtgd+ea=^%_fd!-x5b=fdyh4vv#%#i7_ll#k'

更加详细配置可以参考https://github.com/getsentry/sentry/blob/master/src/sentry/conf/server.py#L351

7）配置完成之后，初始化Sentry数据库：

/var/sentryenv/sentry/bin/sentry --config=/var/sentryenv/sentry/etc/sentry.conf.py upgrade

初始化过程中提示要不要创建用户，创建用户并设置为超级用户。

8）启动Sentry server：

/var/sentryenv/sentry/bin/sentry --config=/var/sentryenv/sentry/etc/sentry.conf.py  start

9）打开端口号

firewall-cmd --zone=public --add-port=9000/tcp --permanentfirewall-cmd --reload

10）浏览器中输入http://192.168.1.112:9000/就可以看到 Sentry的主界面了：

11） 用刚才初始化的用户名和密码登陆。提示如下错误：

解决方法使用普通用户(非root用户登陆linux)，执行以下命令，然后再启动sentry

/var/sentryenv/sentry/bin/sentry --config=/var/sentryenv/sentry/etc/sentry.conf.py celery worker -B

到这边sentry server安装配置完成
