shell客户端连接不上（安卓shell终端工具使用）

Linux Shell Web超级终端工具shellinabox

Shell是Linux内核应用程序，是指“为使用者提供操作界面”的软件，也是命令解析器，它类似于Windows操作系统DOS下的cmd.exe应用程序。它接收用户命令，然后调用相应的应用程序，用户一般管理Linux服务器都是习惯用putty、Xshell、SecureCRT、secure shell等客户端端工具，但是使用这些客户端都是需要在本地安装后才能使用，如果换其它电脑也是需要重新安装，这样非常使用起来非常麻烦，所以，我们今天就来介绍一块非常方便的shell客户端工具，使用系统自带的浏览器来管理Linux服务终端，是一款能随时在任何终端上面管理，这一款运行在linux下面的工具 shellinabox，只需要在Linux服务器上面安装并配置好shellinabox。

shellinabox是由Markus Gutschke创建的基于Web的终端模拟器。它具有内置的Shell Web服务端，在指定端口上作为基于Web的SSH客户端运行，并提示您使用任何支持AJAX/JavaScript和CSS的浏览器远程访问和控制Linux Server SSH Shell，而无需任何其他浏览器插件，使用非常方便，不过安装和配置是需要有点点Linux基础，如果觉得自己完全不懂Linux，可以建议去购买《Linux就该这么学》这本教程，非常适合初学者入门，或者去此教程的官网查看详细的资料，直接在百度输入此书名就可以直接进入官网。

shellinbox是一款在Linux服务器下有一个内建的web server作为基本的web ssh client，允许你通过指定的端口访问linux服务器的ssh shell，只要你的浏览器支持AJAX/JS/CSS就可以访问，不过现在主流的操作系统自带的浏览器都支持，shellinabox是一款开源的轻量级软件，在安装shellinabox之前要确定Linux服务端是否安装了openssl库；debian和ubuntu官方还提供有deb安装包，而centos也有rpm包，也可以通过yum源安装，安装及配置也比较简单，下面我们来详细的安装和配置shellinabox。

一、在RHEL、 CentOS系统上面安装及配置步骤如下

# yum install openssl shellinabox

二、配置shellinaboxd

192.168.3.160是SSH服务器IP地址，

# vim /etc/sysconfig/shellinaboxd

# TCP port that shellinboxd’s webserver listens on

PORT=6175

# specify the IP address of a destination SSH server

OPTS=”-s /:SSH:192.168.3.160″ #(https协议)

#OPTS=”-t -s /:SSH:192.168.3.160″ #(http协议)

# if you want to restrict access to shellinaboxd from localhost only

#下面配置是仅主机访问，其它主机不能访问

#OPTS=”-s /:SSH:192.168.3.160 –localhost-only”

shellinaboxd默认端口是：4200,我这里修改为6175。

Shellinaboxd常用参数使用的帮助手册

# shellinaboxd –help

List of command line options:

-b, –background[=PIDFILE] run in background

-c, –cert=CERTDIR set certificate dir (default: $PWD)

–cert-fd=FD set certificate file from fd

–css=FILE attach contents to CSS style sheet

–cgi[=PORTMIN-PORTMAX] run as CGI

-d, –debug enable debug mode

-f, –static-file=URL:FILE serve static file from URL path

-g, –group=GID switch to this group (default: nobody)

-h, –help print this message

–linkify=[none|normal|aggressive] default is “normal”

–localhost-only only listen on 127.0.0.1

–no-beep suppress all audio output

-n, –numeric do not resolve hostnames

-m, –messages-origin=ORIGIN allow iframe message passing from origin

–pidfile=PIDFILE publish pid of daemon process

-p, –port=PORT select a port (default: 4200)

-s, –service=SERVICE define one or more services

-t, –disable-ssl disable transparent SSL support

–disable-ssl-menu disallow changing transport mode

–disable-utmp-logging disable logging to utmp and wtmp

-q, –quiet turn off all messages

–unixdomain-only=PATH:USER:GROUP:CHMOD listen on unix socket

-u, –user=UID switch to this user (default: nobody)

–user-css=STYLES defines user-selectable CSS options

-v, –verbose enable logging messages

–version prints version information

–disable-peer-check disable peer check on a session

三、启动、停止、自启动服务

Centos 6

# service shellinaboxd start //启动服务

# service shellinaboxd stop //停止服务

# service shellinaboxd restart //重启服务

# chkconfig shellinaboxd on //自启服务

Centos 7

# systemctl start shellinaboxd.service

# systemctl stop shellinaboxd.service

# systemctl restart shellinaboxd.service

# systemctl enable shellinaboxd.service

强制关闭 Shellinaboxd

查找到 Shellinaboxd 的进程 pid ，kill 即可

# ps -aux|grep shellinaboxd | grep -v grep | awk ‘{print $1}’

也可在启动时加上 -p 参数，将进程 pid 保存到指定的文件中，需要关闭时读取它并进行 kill

四、查看服务状态

# netstat -nap | grep shellinabox

tcp 0 0 0.0.0.0:6175 0.0.0.0:* LISTEN 118916/shellinaboxd

默认60s不登录自动断开
