这篇文章与使用 YUM 安装 Sensu相结合，用于安装、配置和启动 Sensu 及相关服务：

sudo yum install -y erlang && \
sudo rpm -Uvh http://www.rabbitmq.com/releases/rabbitmq-server/v3.5.0/rabbitmq-server-3.5.0-1.noarch.rpm && \
sudo yum install -y redis && \
echo '[sensu]
name=sensu
baseurl=http://sensu.global.ssl.fastly.net/yum/$basearch/
gpgcheck=0
enabled=1' | sudo tee /etc/yum.repos.d/sensu.repo && \
sudo yum install -y sensu && \
sudo yum install -y uchiwa && \
for s in rabbitmq-server redis.service sensu-server sensu-api uchiwa; do sudo systemctl restart $s; done && \
sudo rabbitmqctl add_vhost /sensu && \
sudo rabbitmqctl add_user sensu secret && \
sudo rabbitmqctl set_permissions -p /sensu sensu ".*" ".*" ".*"

分析

  • 导航到 :3000 显示 uchiwa 仪表板并指示Connection error. Is the Sensu API running?
  • /var/log/sensu/sensu-api.log 表示
{"timestamp":"2016-07-03T22:58:58.532905+0000","level":"warn","message":"config file does not exist or is not readable","file":"/etc/sensu/config.json"}
{"timestamp":"2016-07-03T22:58:58.533069+0000","level":"warn","message":"ignoring config file","file":"/etc/sensu/config.json"}

  • config.json 似乎不存在（/etc/sensu/config.json: No such file or directory）
  • 下载示例 config.json并重新启动 sensu-api 并没有解决问题

  • redis端口正在监听：

  • rabbitmq 端口：

  • Uchiwa 无法连接到数据中心

  • 导航到<IPADDRESS>:4567结果：
{"error":"redis and transport connections not initialized"}
  • redis 回复
sudo redis-cli ping
PONG
  • redis密码已设置，但问题仍然存在
sudo redis-cli
127.0.0.1:6379> auth secret
OK
