阿里云使用笔记-第六篇-CentOS搭建Sentry日志监控平台

一,前言

由于前端项目运行在用户各自电脑的浏览器上,
对于浏览器差异所导致的问题,正常情况下是没有办法拿到的
我们可以使用日志监控平台对客户端产生的问题进行收集统计,以便及时处理

搭建Sentry(哨兵)日志平台,对前端项目日志进行上报并及时处理解决问题

---

二,安装docker

安装:

yum -y install docker-ce

启动:

systemctl start docker

测试:

docker run hello-world

[root@Brave ~]# docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
1b930d010525: Pull complete 
Digest: sha256:2557e3c07ed1e38f26e389462d03ed943586f744621577a99efb77324b0fe535
Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:
 https://hub.docker.com/
For more examples and ideas, visit:
 https://docs.docker.com/get-started/

查看docker版本

docker --version

[root@Brave ~]# docker --version
Docker version 18.09.3, build 774a1f4

---

如果需要删除旧版本docker:

卸载旧版本Docker

yum remove docker  docker-common  docker-selinux  docker-engine

安装依赖

yum install -y yum-utils   device-mapper-persistent-data   lvm2

添加docker yum源

yum-config-manager     --add-repo     https://download.docker.com/linux/centos/docker-ce.repo

可选操作：允许拓展最新的不稳定的repository

yum-config-manager --enable docker-ce-edge

---

三,安装epel, python-pip, docker-compose, git

[root@Brave ~]# pip install --upgrade pip
yum install epel-release
yum  install -y python-pip
pip  install docker-compose
yum install git

---

四,获取sentry

获取sentry:

git clone https://github.com/getsentry/onpremise.git

查看README.md文件:https://github.com/getsentry/onpremise

五,安装sentry

按照readme文件中提供的安装顺序

1,创建卷

[root@Brave ~]# cd onpremise/
[root@Brave onpremise]# docker volume create --name=sentry-data && docker volume create --name=sentry-postgres
sentry-data
sentry-postgres

2,创建环境配置

[root@Brave onpremise]# cp -n .env.example .env

3, Build

[root@Brave onpremise]# docker-compose build
smtp uses an image, skipping
memcached uses an image, skipping
redis uses an image, skipping
postgres uses an image, skipping

bj==04k)47l5m=ll%ju!zfmfywn8cow+misgx&w=gh86jg)nmk

拷贝最后一行的秘钥:

bj==04k)47l5m=ll%ju!zfmfywn8cow+misgx&w=gh86jg)nmk

5,替换秘钥

打开文件:

vi docker-compose.yml 

添加秘钥到SENTRY_SECRET_KEY:

esc :wq+回车保存退出

6,运行 docker-compose run --rm web upgrade
该过程会要求输入 用户邮箱 和 密码

六,开放阿里云端口

进入权限组,为sentry开放9000端口

七,访问Sentry

打开http://ip:9000 访问sentry

可以看到sentry支持的语言很多

八,结尾

这样,Sentry就安装完成了,对于中小公司的项目Sentry一般是没有问题的
同类产品还可以考虑使用潘多拉,有更好的性能支持扩展和更高的流量

前端有了sentry这样的日志上报平台,
可以对客户端发生的异常做收集,及时处理浏览器差异导致的问题,
有效到获取到应用上线发布后在客户端发生的问题,
及时修复提高程序健壮性,改善用户体验
