使用Docker 方式在Centos 7.0 安装配置Sentry

2017-12-21 15:04 701 查看

一、简介
sentry是一个强大的分布式报错信息收集平台，图形化程度很高，可以帮助我们直观的发现当前部署的系统存在哪些问题。
二、安装方式介绍
官网链接：https://docs.sentry.io/
官方提供了两种安装方式：Docker 和 python
注：我这里选择使用Docker 的方式来进行安装配置sentry，原因是官网说了python这种方式已经被Docker安装方式代替了，原话如下：

This method of installation is deprecated in favor of Docker 而且使用python安装sentry必须是python 2.7 以及以上版本，考虑到升级python 会影响系统其它应用，故此选择Docker的安装方式。三、安装配置过程1、准备工作在服务器安装好Centos 7.x 系统，我这里安装的是Centos 7.0 ，而且python在Centos 7.0上的版本就是2.7.52、安装docker官方Docker 安装方式帮助文档：https://docs.sentry.io/server/installation/docker/

安装epel源
#yum  install epel-release -y

安装pip
#yum install python-pip -y
查看版本：
#pip -V
pip 8.1.2 from /usr/lib/python2.7/site-packages (python 2.7)

3、安装docker-composeDocker Compose 是在使用Docker容器部署分布式应用时的工具，可以定义哪个容器运行哪个应用，使用Compose 你只需定义一个多容器应用的yml文件，然后使用一条命令即可部署运行所有容器。
参考链接：http://dockone.io/article/834
中文指南网：http://www.widuu.com/docker/compose/install.html

使用pip来安装docker compose
#pip install docker-compose

#pip list     #可以看到docker-compose 已经安装好了
backports.ssl-match-hostname (3.5.0.1)
cached-property (1.3.1)
certifi (2017.11.5)
chardet (3.0.4)
configobj (4.7.2)
decorator (3.4.0)
docker (2.6.1)
docker-compose (1.18.0)    #已安装
………………

#docker-compose  --version   #查看版本
docker-compose version 1.18.0, build 8dd22a9

4、配置安装属于自己的sentry

#mkdir /opt/case -pv
#cd /opt/case/
#git clone https://github.com/getsentry/onpremise.git #cd onpremise

根据onpremise目录中的README.md 内容来操作：
#cat README.md
………………
1. `mkdir -p data/{sentry,postgres}` - Make our local database and sentry config directories.
This directory is bind-mounted with postgres so you don't lose state!
2. `docker-compose run --rm web config generate-secret-key` - Generate a secret key.
Add it to `docker-compose.yml` in `base` as `SENTRY_SECRET_KEY`.
3. `docker-compose run --rm web upgrade` - Build the database.
Use the interactive prompts to create a user account.
4. `docker-compose up -d` - Lift all services (detached/background mode).
5. Access your instance at `localhost:9000`!
………………

#mkdir data/{sentry,postgres} -p

启动docker
#systemctl start  docker
加入开机自启动
#systemctl enable docker

正常启动之后，会有docker0网卡生成
#ifconfig
docker0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
inet 172.17.0.1  netmask 255.255.0.0  broadcast 0.0.0.0

RX errors 0  dropped 0  overruns 0  frame 0
TX packets 0  bytes 0 (0.0 B)
TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

在docker-compose.yml中的base位置添加 SENTRY_SECRET_KEY，使用如下命令生成
#docker-compose run --rm web config generate-secret-key        #需要很长时间，需要到外网拉取数据，如果中间断掉了，继续执行即可。

注：如果第一次没有生成SENTRY_SECRET_KEY，多执行几次直到生成为止，我就执行了4次，如下：
#docker-compose run --rm web config generate-secret-key
Starting onpremise_memcached_1 ...
Starting onpremise_redis_1 ...
Starting onpremise_memcached_1 ... done
Starting onpremise_smtp_1 ... done
_&vh6fx-80!q20g+jhvj5m6(!(-jy^x7t46_-7vtz2(=)+=#%v

将上面命令执行结束后生成的最后一行字符串，添加到docker-compose.yml 中，如下：
#cat docker-compose.yml
…………………………
version: '2'
services:
base:
restart: unless-stopped
build: .
environment:
# Run `docker-compose run web config generate-secret-key`
# to get the SENTRY_SECRET_KEY value.
# SENTRY_SECRET_KEY: ''
SENTRY_SECRET_KEY: '_&vh6fx-80!q20g+jhvj5m6(!(-jy^x7t46_-7vtz2(=)+=#%v'     #添加此行
SENTRY_MEMCACHED_HOST: memcached
SENTRY_REDIS_HOST: redis
SENTRY_POSTGRES_HOST: postgres
SENTRY_EMAIL_HOST: smtp
volumes:
- ./data/sentry:/var/lib/sentry/files

注：在执行下面一步的时候，需要关闭selinux并且配置docker-compose.yml，否则如果后面再关闭selinux，就会遇到启动报错，后面会介绍！
#cat  /etc/selinux/config
SELINUX=disabled           #改成disabled
在docker-compose.yml 中添加选项：privileged: true 如下样式：
#cat docker-compose.yml
………………
version: '2'
services:
base:
privileged: true                    #添加到这个位置
restart: unless-stopped
build: .
environment:
# Run `docker-compose run web config generate-secret-key`
# to get the SENTRY_SECRET_KEY value.
# SENTRY_SECRET_KEY: ''
SENTRY_SECRET_KEY: '_&vh6fx-80!q20g+jhvj5m6(!(-jy^x7t46_-7vtz2(=)+=#%v'
SENTRY_MEMCACHED_HOST: memcached
SENTRY_REDIS_HOST: redis
SENTRY_POSTGRES_HOST: postgres
SENTRY_EMAIL_HOST: smtp

smtp:

restart: unless-stopped

memcached:
privileged: true                    #添加到这位置，下面的服务也是添加到同样的位置，不在列出
restart: unless-stopped
image: memcached:1.4
………………

然后重启系统
#reboot

#docker-compose up -d          #拉起所有的服务    Lift all services (detached/background mode).

使用docker-compose 管理服务
#cd /opt/case/onpremise
#docker-compose start  #将上面的服务全部启动
Starting postgres  ... done
Starting redis     ... done
Starting smtp      ... done
Starting base      ... done

Starting web       ... done

#docker-compose ps     #查看是否启动ok，可以看到都是Up状态

onpremise_base_1        /entrypoint.sh run web           Up      9000/tcp
onpremise_cron_1        /entrypoint.sh run cron          Up      9000/tcp
onpremise_memcached_1   docker-entrypoint.sh memcached   Up      11211/tcp
onpremise_postgres_1    docker-entrypoint.sh postgres    Up      5432/tcp
onpremise_redis_1       docker-entrypoint.sh redis ...   Up      6379/tcp
onpremise_smtp_1        entrypoint.sh tini -- exim ...   Up      25/tcp
onpremise_web_1         /entrypoint.sh run web           Up      0.0.0.0:9000->9000/tcp
onpremise_worker_1      /entrypoint.sh run worker        Up      9000/tcp

Access your instance at `localhost:9000`! 即配置访问实例的ip和端口
#vi docker-compose.yml   #在web 配置项添加如下：
web:
privileged: true
restart: unless-stopped
extends: base
links:
- redis
- postgres
- memcached
- smtp
ports:
- '172.16.60.167:9000:9000'    #添加sentry所在服务器的ip地址

然后就可以在浏览器访问了http://172.16.60.167:900  输入上面设置的用户名和密码，就可以进入，如下图

第一次登陆需要进行一些简单的设置，点击“登陆”之后，出现如下界面，进行一些设置

设置好之后，直接点击右下角的“continue” 就会进入到主机面，如下：

至此sentry的安装配置告一段落，具体创建项目或者其他操作需要根据开发需要进行配置。四、遇到的问题

1、执行docker-compose start 报错
问题描述：
按照/opt/case/onpremise/README.md 中的1-5 操作之后，准备将selinux关闭，于是就在配置文件/etc/selinux/config中将参数改了---> SELINUX=disabled 重启
系统之后，再次执行#docker-compose start 报错 如下：
Starting postgres ... error
Starting redis ... error
Starting smtp ... error
Starting base ... error
Starting memcached ... error
Starting worker ... error
Starting cron ... error
Starting web ... error

ERROR: for memcached Cannot start service memcached: devmapper: Error mounting '/dev/mapper/docker-8:2-263372-b60cf0da925b9971fb7103e576b9e0f088451e8203ebb07ebadff4adaee2fb4e' on '/var/lib/docker/devicemapper/mnt/b60cf0da925b9971fb7103e576b9e0f088451e8203ebb07ebadff4adaee2fb4e': invalid argument

ERROR: for smtp Cannot start service smtp: devmapper: Error mounting '/dev/mapper/docker-8:2-263372-501013d66a63bfb0e331ee1e3d7924ceddfc5117a0eb13673cdc03c6ba629da0' on '/var/lib/docker/devicemapper/mnt/501013d66a63bfb0e331ee1e3d7924ceddfc5117a0eb13673cdc03c6ba629da0': invalid argument

ERROR: No containers to start
网上找了一些方法，但是不能解决问题，其中一个就是执行umount命令，如下
#umount /var/lib/docker/devicemapper/mnt/xxxx

后来在高人的指点下，说是selinux的问题。因为我是在配置SELINUX=disabled 之前执行的#docker-compose up -d

解决方法:
1、将selinux配置文件中的配置还原：SELINUX=enforcing 然后reboot系统，执行#docker-compose start 就可以正常启动了。
2、在/opt/case/onpremise/docker-compose.yml 中添加一个配置项：privileged: true
如下：
smtp:
privileged: true ##在每一个服务下面都要添加这个选项，一共8个
restart: unless-stopped
image: tianon/exim4

重启系统
#reboot

3、再将selinux 配置文件中改为disabled
SELINUX=disabled

4、执行docker-compose up
#docker-compose up -d #会重新创建服务
Recreating onpremise_smtp_1 ...
Recreating onpremise_postgres_1 ...
Recreating onpremise_memcached_1 ...
Recreating onpremise_redis_1 ...
Recreating onpremise_postgres_1 ... done
Recreating onpremise_web_1 ...
Recreating onpremise_cron_1 ...
Recreating onpremise_worker_1 ... done

5、启动
#docker-compose start
Starting postgres ... done
Starting redis ... done
Starting smtp ... done
Starting base ... done
Starting memcached ... done
Starting worker ... done
Starting cron ... done
Starting web ... done

注：后面再reboot之后，就不会出现执行docker-compose start 报错的问题了。

五、使用代理说明：如果是在生产环境部署sentry，就不希望自己之外的其他人访问，这个时候可以通过nginx设置认证登录或者代理的方式访问

这里介绍使用代理的方式：
#cat /opt/app/nginx/conf/conf.d/vhost.conf
upstream www {
server 172.168.100.26:9000;      #服务器内网ip地址
}
#-----------------------------------------------------------------------------
server {
listen       80;
server_name  sentry.test.com;
access_log   /opt/logs/nginx/sentry.test.com.access.log  main;
error_log    /opt/logs/nginx/sentry.test.com.error.log   warn;

location / {
proxy_pass          http://www; }

}

server {
listen       443;
server_name  sentry.test.com;
access_log   /opt/logs/nginx_ssl/sentry.test.com.access.log  ssl;
error_log    /opt/logs/nginx_ssl/sentry.test.com.error.log   warn;

ssl             on;
ssl_certificate         /opt/app/nginx/conf/ssl/test.com.pem;
ssl_certificate_key     /opt/app/nginx/conf/ssl/test.com.key;

location / {
proxy_pass      http://www; }
}
然后启动nginx服务
#/opt/app/nginx/sbin/nginx

#netstat -tunlp  | grep nginx
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
