官方文档：https://github.com/NarrativeScience/Log.io/wiki/v0.3.4-Build-Recipe-(Ubuntu-14.04)
The following recipe was used to build a Log.io environment on a fresh Ubuntu 14.04 install (ami-864d84ee), using node.js v0.10.29
1.安装node.js和cnpm
详细步骤：https://blog.51cto.com/qiangsh/2095944
2.安装log.iocnpm install -g log.io --user "root"
----root为用户名，这里必须指定一个用户名。因为 log.io 需要在用户的根目录里面建立目录，存放配置信息。
报错信息：

解决方法：
wget http://people.centos.org/tru/devtools-2/devtools-2.repo
yum install devtoolset-2-gcc devtoolset-2-gcc-c++ scl-utils
export CC=/opt/rh/devtoolset-2/root/usr/bin/gcc
export CPP=/opt/rh/devtoolset-2/root/usr/bin/cpp
export CXX=/opt/rh/devtoolset-2/root/usr/bin/c++
scl enable devtoolset-2 bash3.上三步在server和client端都要安装，安装完成后，会在~/.log.io/目录下生成以下几个文件
harvester.conf #客户端配置
log_server.conf
web_server.conf #服务端配置 4.服务端配置
vim web_server.conf
exports.config = {
host: '0.0.0.0',
port: 28778,
// Enable HTTP Basic Authentication
auth: {
user: "admin",
pass: "123456"
},
/*
// Enable HTTPS/SSL
ssl: {
key: '/path/to/privatekey.pem',
cert: '/path/to/certificate.pem'
},
*/
/*
// Restrict access to websocket (socket.io)
// Uses socket.io 'origins' syntax
restrictSocket: '*:*',
*/
/*
// Restrict access to http server (express)
restrictHTTP: [
"192.168.29.39",
"10.0.*"
]
*/
} 5.客户端配置,设置日志收集来源
vim /root/.log.io/harvester.conf
exports.config = {
nodeName: "nodeB", ####修改节点名称（自定义）
logStreams: {
nginx_access: [ ####日志服务的名称（自定义）
"/var/log/nginx/access.log", ###日记存储路径
],
nginx_error: [ ####日志服务的名称（自定义）
"/var/log/nginx/error.log" ###日记存储路径
]
},
server: {
host: '10.10.0.2', ####log.io Server端的IP
port: 28777 ####log.io Server端的端口（默认端口）
}
} 6.启动服务端nohup log.io-server &
7.启动客户端nohup log.io-harvester &
8.修改log.io的一处bug
vi /usr/local/lib/node_modules/log.io/lib/harvester.js
if (event === 'change') {
return fs.stat(path, function(err, stat) {
var tmp_total = !err ? (stat.size || 0) : 0;
if (tmp_total > 0) {
_this._readNewLogs(path, tmp_total, currSize);
return currSize = tmp_total;
} else {
return tmp_total;
}
});
}9.其他问题
给npm设置代理
npm config set proxy=http://127.0.0.1:8087
npm config set registry=http://registry.npmjs.org 切换npm源，可以用淘宝的
