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puttyXshellSecureCRTsecure 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WebSSH客户端运行,并提示您使用任何支持AJAX/JavaScriptCSS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;debianubuntu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

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

https://192.168.3.160:6175/
