安裝實時查看日誌工具 log.io

 

官網：http://logio.org/

1、環境

[root@centos ~]# cat /etc/system-release
CentOS release 6.5 (Final)
[root@centos ~]# uname -a
Linux centos 2.6.32-431.11.31.el6.ucloud.x86_64 #1 SMP Tue Mar 7 20:19:50 EST 2017 x86_64 x86_64 x86_64 GNU/Linux

 

2、安裝

　　一、安裝 npm

　　　　我使用的是epel源的rpm包，若是沒有epel源，能夠 yum install -y epel.repo

　　　　

[root@centos ~]# yum install -y npm
[root@centos ~]# npm -v
1.3.6

 

 

3、安裝log.io

npm install -g log.io --user "root"

 

若是安裝時報以下錯誤：

npm http GET https://registry.npmjs.org/log.io
npm http GET https://registry.npmjs.org/log.io
npm http GET https://registry.npmjs.org/log.io

解決辦法參考：https://stackoverflow.com/questions/21855035/ssl-error-cert-untrusted-while-using-npm-command

在命令行執行：

npm config set strict-ssl false

 

而後再次嘗試安裝log.io：

[root@centos ~]# npm install -g log.io --user "root"

 

若是成功安裝會有以下文件：

[root@centos ~]# ls /root/.log.io/
harvester.conf  log_server.conf  web_server.conf
[root@centos ~]# which log.io-server 
/usr/bin/log.io-server
[root@centos ~]# which log.io-harvester
/usr/bin/log.io-harvester
