Shell 是核心應用程式，是指“為使用者提供操作介面”的軟體，也是命令解析器，它類似於Windows作業系統DOS下的cmd.exe應用程式。它接收使用者命令，然後呼叫相應的應用程式，使用者一般管理Linux伺服器都是習慣用putty、Xshell、SecureCRT、secure shell等客戶端端工具，但是使用這些客戶端都是需要在本地安裝後才能使用，如果換其它電腦也是需要重新安裝，這樣非常使用起來非常麻煩，所以，我們今天就來介紹一塊非常方便的shell客戶端工具，使用系統自帶的瀏覽器來管理Linux服務終端，是一款能隨時在任何終端上面管理，這一款執行在linux下面的工具 shellinabox，只需要在Linux伺服器上面安裝並配置好shellinabox。

shellinabox 是由Markus Gutschke建立的基於Web的終端模擬器。它具有內建的Shell Web服務端，在指定埠上作為基於Web的SSH客戶端執行，並提示您使用任何支援AJAX/JavaScript和CSS的瀏覽器遠端訪問和控制Linux Server SSH Shell，而無需任何其他瀏覽器外掛，使用非常方便，不過安裝和配置是需要有點點Linux基礎，如果覺得自己完全不懂Linux，可以建議去購買這本教程，非常適合初學者入門，或者去此教程的官網檢視詳細的資料，直接在百度輸入此書名就可以直接進入官網。

shellinbox 是一款在Linux伺服器下有一個內建的web server作為基本的web ssh client，允許你透過指定的埠訪問linux伺服器的ssh shell，只要你的瀏覽器支援AJAX/JS/CSS就可以訪問，不過現在主流的作業系統自帶的瀏覽器都支援，shellinabox是一款開源的輕量級軟體，在安裝shellinabox之前要確定Linux服務端是否安裝了openssl庫；debian和ubuntu官方還提供有deb安裝包，而centos也有rpm包，也可以透過yum源安裝，安裝及配置也比較簡單，下面我們來詳細的安裝和配置shellinabox。

一、在RHEL、 CentOS系統上面安裝及配置步驟如下

# yum install openssl shellinabox

二、配置shellinaboxd

192.168.3.160 是SSH伺服器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 協議)

#OPTS="-t -s /:SSH:192.168.3.160" #(http 協議)

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

# 下面配置是僅主機訪問，其它主機不能訪問

#OPTS="-s /:SSH:192.168.3.160 --localhost-only"

shellinaboxd 預設埠是：4200,我這裡修改為6175。

Shellinaboxd 常用引數使用的幫助手冊

# 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-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、啟動、停止、自啟動服務

Centos 6

# service shellinaboxd start // 啟動服務

# service shellinaboxd stop // 停止服務

# service shellinaboxd restart // 重啟服務

# chkconfig shellinaboxd on // 自啟服務

Centos 7

# systemctl start shellinaboxd.service

# systemctl stop shellinaboxd.service

# systemctl restart shellinaboxd.service

# systemctl enable shellinaboxd.service

強制關閉 Shellinaboxd

查詢到 Shellinaboxd 的程式 pid ，kill 即可

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

也可在啟動時加上 -p 引數，將程式 pid 儲存到指定的檔案中，需要關閉時讀取它並進行 kill

四、檢視服務狀態

# 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/
