# CentOS7 安装log.io服务 #

> 官网： [http://logio.org/][http_logio.org]

*  添加epel源

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

## 安裝Log.io: ##

*  服务架构，安装依赖

![这里写图片描述][70]

# 安装开发工具包或者 yum install gcc-c++
    yum install npm nodejs
    
    # npm是jabascript的软件包管理器，允许管理应用程序的依赖关系，也允许用户从npm注册表安装node.js应用程序。输入一个用户名来安装，筆者使用了“yunwei”用户
    npm install -g log.io --user "root"

## 配置 Log.io ##

> Log.io的Installed目录是〜/ .log.io，它是用户主目录下的一个隐藏目录，在prevoius步骤中用于安装，它有三个配置文件来控制它的工作性质。

*  harvester.conf

> 这是收割机的配置文件，它不过是一个日志转发器，它不断监视日志文件的变化，向服务器发送新日志。

# vi ~/.log.io/harvester.conf
    # cat harvester.conf 
    exports.config = {
      nodeName: "log.io",
      logStreams: {
        systeminfo: [
          "/var/log/messages",
          "/var/log/secure"
        ],
        logioaccess: [
          "/var/log/nginx/logio.aniu.so.access.log"
        ],
        logiolog: [
          "/root/.log.io/log.io-server.log"
        ]
      },
      server: {
        host: '192.168.0.24',
        port: 28777
      }
    }
    
    # 编辑log_server.conf 
    [root@ecs-01 .log.io]# cat log_server.conf 
    exports.config = {
      host: '192.168.0.24',
      port: 28777
    }
    
    # 编辑web_server.conf
    [root@nkmapi-1 .log.io]# cat web_server.conf 
    exports.config = {
      host: '0.0.0.0',
      port: 28778,
    
      /* 
      // Enable HTTP Basic Authentication
      auth: {
        user: "admin",
        pass: "1234"
      },
      */
    
      /* 
      // 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.*", # 笔者只改了这里 其他没改
        "192.168.0.*"
      ]
      */
    
    }

*  配置启动脚本

# cat /etc/init.d/log.io 
    #!/bin/bash 
    start() {
           echo "Starting log.io process..."
           /usr/bin/nohup /usr/bin/log.io-server >> /root/.log.io/log.io-server.log 2>&1 &
           /usr/bin/nohup /usr/bin/log.io-harvester >> /root/.log.io/log.io-harvester.log 2>&1 &
    }
    
    stop() {
          echo "Stopping io-log process..."
          pkill node
    }                             
    
    status() {
          echo "Status io-log process..."
          netstat -tlp | grep node
    }
    
    case "$1" in
         start)
         start
         ;;
         stop)
         stop
         ;;
         status)
         status
         ;;
         restart)
         echo "Restart log.io process..."
         $0 stop
         $0 start
         ;;
         *)
         echo "Usage: start|stop|restart|status"
         ;;
    esac

*  启动logio

# 正常安装配置完成，启动logio
    /etc/init.d/log.io start

*  浏览器查看

## 收集tomcat实时日志 ##

*  centos6/7 上java api客户端执行：

# 配置epel源
    yum install npm nodejs gcc-c++
    npm config set strict-ssl false
    npm install -g log.io --user "root"

*  配置log.io配置

# 注意client端只需要修改harvester配置文件即可
    # cat harvester.conf 
    exports.config = {
      nodeName: "liquidation-master",
      logStreams: {
        tomcat_8082: [
          "/data/tomcats/tomcat-8082/logs/catalina.out"
        ]
      },
      server: {
        host: '192.168.0.24',
        port: 28777
      }
    }

*  收集日志的服务器，也要安装log.io,正常笔者认为启动harvester即可，但是没成功，笔者还是每个客户端都启动了两个服务
