官网
log.io是运行在node.js之上的
可通过浏览器访问服务器日志
类似于tail -f命令
它只负责实时传输数据
而不会去存储历史数据
大白话：可以使用web网页在线看log，但不能看历史的log
开始安装：
1 # 安装log.io 2 cnpm install -g log.io --"root" 3 4 # 可以使用淘宝的npm镜像 5 cnpm --registry https://registry.npm.taobao.org install -g log.io --user "root"
注意：此处可能会报错，如下：

解决方案：
1 # z shell 2 yum install -y zsh 3 4 zsh 5 6 # install n 7 cnpm install -g n 8 9 # install node 6.17.1 10 n 6.17.1 11 12 # 查看node版本是否切换为6.17.1 13 node -v 14 15 # 重新安装cnpm 16 npm install -g cnpm --registry=https://registry.npm.taobao.org 17 18 # now, install log.io 19 cnpm install -g log.io 20 21 问题描述：https://github.com/NarrativeScience/Log.io/issues/205
配置文件在~/.log.io目录下
harvester.conf：客户端配置文件
log_server.conf：服务端配置文件
web_server.conf：Web端配置文件
修改客户端配置文件
1 vim ~/.log.io/harvester.conf
启动
1 # 先启动服务端 2 log.io-server 3 4 # 再启动客户端 5 log.io-harvester
再访问
