prometheus stack workshop

安装Vagrant环境

• 下载安装 virtualbox 5.2 for OSX
• 下载安装 vagrant 2.1.2 for OSX

启动vagrant初始化VM

1. clone 代码仓库

git clone https://github.com/itwye/prometheus-stack-workshop.git

cd prometheus-stack-workshop

2. 使用vagrant 启动VM

# 在 prometheus-stack-workshop 目录下执行

vagrant up

因需要安装docker,docker-compose等，如网络下载速度慢，可能会执行很长时间,请耐心等待...！

Notes： 如果vagrant 初始化中途网络中断

在下载box阶段中断可以直接 vagrant up 重新下载 box

在shell脚本安装初始化系统阶段中断，可以使用 vagrant up --provision 重新初始化

3. VM启动后,登录进入VM，启动prometheus stack所有组件。

# -------------
# 查询VM状态
# -------------
$ vagrant status

Current machine states:

test-node                 running (virtualbox)

# -------------
# 登录test-node VM
# -------------
$ vagrant ssh test-node

# -------------
# 切换root用户
# -------------

vagrant@test-node:~$ sudo su -

# ------------
# 启动prometheus stack
# ------------

root@test-node:~# cd /home/vagrant/share/
root@test-node:~# docker-compose up -d

因需要拉取镜像，如网络下载速度慢，可能会执行很长时间，请耐心等待......！

如拉取镜像卡死，先ctrl+c , 再重新docker-compose up -d 即可。

# -----------
# 验证prometheus stack相关container是否启动成功
# -----------

root@test-node:/home/vagrant/share# docker ps

4. 在宿主机浏览器,确保测试环境已OK! (VM IP如你更改过了,下面请替换成你的IP)

(1) Prometheus:   http://192.168.33.118:9090

(2) Grafana:    http://192.168.33.118:3000/   (user/pwd: admin/admin)

(3) Alertmanager:    http://192.168.33.118:9093/

(4) Application metrics:   http://192.168.33.118:8000/

(5) Pushgateway:   http://192.168.33.118:9091/

如VM里容器运行正常，但如上方式不能访问，请在宿主机重启下VM IP网段所在网卡即可。

$ ifconfig

vboxnet3: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
	ether 0a:00:27:00:00:03
	inet 192.168.33.1 netmask 0xffffff00 broadcast 192.168.33.255

$ ifconfig vboxnet3 down
$ ifconfig vboxnet3 up
