需要使用root用戶安裝
1.安裝node.js
node.js安裝包獲取，請搜索。

tar zxvf node-v0.12.7.tar.gz
cd node-v0.12.7
./configure 
make && make install

2.安裝npm
wget --no-check-certificate https://npmjs.org/install.sh && sh install.sh
3.防止npm被墻，使用cnpm替代
npm install -g cnpm --registry=https://registry.npm.taobao.org

vi ~/.log.io/harvester.conf
exports.config = {
nodeName: "test_server_01",
logStreams: {
tomcat: [
"/home/test/local/tomcat/logs/catalina.out"
],
tomcat8030: [
"/home/test/local/tomcat8030/logs/catalina.out"
]
},
server: {
host: ‘0.0.0.0‘,
port: 28777
}
}
 

8.修改log.io的一處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.啟動客戶端
nohup log.io-harvester &
