TTY)。所以它们失败的原因也是相同的：<br>默认情况下，当你执行不带命令的 ssh 连接时，会为你分配一个 TTY。因为此时你应该是想要运行一个 shell 会话。<br>但是当你通过 ssh 在远程主机上执行命令时，并不会为这个远程会话分配 TTY。此时 ssh 会立即退出远程主机，所以需要交互的命令也随之结束。<br>好在我们可以通过 -t 参数显式的告诉 ssh，我们需要一个 TTY 远程 shell 进行交互！<br>添加 -t 参数后，ssh 会保持登录状态，直到你退出需要交互的命令。</p>\n<h2 id=\"执行本地脚本\"><a href=\"#执行本地脚本\" class=\"headerlink\"

class=\"code\"><pre><span class=\"line\"><span class=\"meta\">$</span><span class=\"bash\"> cat test.sh</span> </span><br><span class=\"line\">ls</span><br><span class=\"line\">pwd</span><br><span class=\"line\"> </span><br><span class=\"line\"><span class=\"meta\">$</span><span class=\"bash\"> ssh root@10.153.195.138 &lt; test.sh</span> </span><br><span class=\"line\">anaconda-ks.cfg</span><br><span class=\"line\">/root</span><br></pre></td></tr></table></figure>\n\n<p>通过重定向 stdin，本地的脚本 test.sh 在远程服务器上被执行。</p>\n<p><strong>2、为脚本传递参数：</strong></p>\n<figure class=\"highlight shell\"><table><tr><td class=\"code\"><pre><span class=\"line\"><span class=\"meta\">$</span><span class=\"bash\"> cat test.sh</span> </span><br><span class=\"line\">echo $1</span><br><span class=\"line\">echo $2</span><br><span class=\"line\"> </span><br><span class=\"line\">在本地执行结构如下：</span><br><span class=\"line\"><span class=\"meta\">$</span><span class=\"bash\"> sh test.sh a b</span></span><br><span class=\"line\">a</span><br><span class=\"line\">b</span><br><span class=\"line\"></span><br><span class=\"line\">通过重定向远程执行，会报错</span><br><span class=\"line\"><span class=\"meta\">$</span><span class=\"bash\"> ssh root@10.153.195.138 &lt; test.sh a b</span></span><br><span class=\"line\">bash: a: command not found</span><br></pre></td></tr></table></figure>\n\n<p>看来上面的方法都无法为脚本传递参数。<br>要想在这种情况下(远程执行本地的脚本)执行带有参数的脚本，需要为 bash 指定 -s 参数：</p>\n<figure class=\"highlight shell\"><table><tr><td class=\"code\"><pre><span class=\"line\"><span class=\"meta\">$</span><span class=\"bash\"> ssh root@10.153.195.138 <span class=\"string\">&#x27;bash -s&#x27;</span> &lt; test.sh a b</span></span><br><span class=\"line\">a</span><br><span class=\"line\">b</span><br></pre></td></tr></table></figure>\n\n<p>除此之外，我们还可以通过替换的方式传参，然后远程执行，例如：</p>\n<figure class=\"highlight plain\"><table><tr><td class=\"code\"><pre><span class=\"line\">cat .&#x2F;rollback_remote.sh | sed -e &quot;s&#x2F;#module#&#x2F;$&#123;MODULE_NAME&#125;&#x2F;g&quot; -e &quot;s&#x2F;#runarg#&#x2F;$&#123;RUN_ARG&#125;&#x2F;g&quot; | ssh $IP</span><br></pre></td></tr></table></figure>\n\n<h2 id=\"执行远程服务器上的脚本\"><a href=\"#执行远程服务器上的脚本\" class=\"headerlink\" title=\"执行远程服务器上的脚本\"></a>执行远程服务器上的脚本</h2><p>除了执行本地的脚本，还有一种情况是脚本文件存放在远程服务器上，而我们需要远程的执行它！此时在远程服务器上用户 nick 的家目录中有一个脚本 test.sh。文件的内容如下：</p>\n<figure class=\"highlight shell\"><table><tr><td class=\"code\"><pre><span class=\"line\">ls</span><br><span class=\"line\">pwd</span><br><span class=\"line\">执行下面的命令即可（注：一定是绝对路径）：</span><br><span class=\"line\"><span class=\"meta\">$</span><span class=\"bash\"> ssh nick@xxx.xxx.xxx.xxx <span class=\"string\">&quot;/home/nick/test.sh&quot;</span></span></span><br></pre></td></tr></table></figure>\n\n<p>下面我们也尝试为脚本传递参数。在远程主机上的 test.sh 文件的末尾添加两行：</p>\n<figure class=\"highlight shell\"><table><tr><td class=\"code\"><pre><span class=\"line\">echo $0</span><br><span class=\"line\">echo $1</span><br><span class=\"line\">然后尝试执行下面的命令：</span><br><span class=\"line\"> </span><br><span class=\"line\"><span class=\"meta\">$</span><span class=\"bash\"> ssh nick@xxx.xxx.xxx.xxx /home/nick/test.sh helloworld</span></span><br></pre></td></tr></table></figure>\n\n<p>可以正确得到结果。</p>\n<h2 id=\"执行多行命令\"><a href=\"#执行多行命令\" class=\"headerlink\"

class=\"line\">/root</span><br></pre></td></tr></table></figure>\n\n<p>你可以用单引号或双引号开头，然后写上几行命令，最后再用相同的引号来结束。</p>\n<p>当我们在命令中引用了变量时会怎么样呢？</p>\n<figure class=\"highlight shell\"><table><tr><td class=\"code\"><pre><span class=\"line\"><span class=\"meta\">$</span><span class=\"bash\"> name=<span class=\"built_in\">test</span></span></span><br><span class=\"line\"><span

就是之前我写过的那个关于expect有关的文章，问题是jenkins中默认的shell解释器只有bash，不能更改解释器的。所以就很难受，国内的百度基本都是搬运过来的内容，毫无意义，浪费时间，在国外博客浪荡几天之后终于找到了解决方案。</p>\n<p>下面我来分享一下，大致意思呢就是执行完ssh 连接远程主机之后需要执行的命令，可以进行如下操作，命令不要照抄，换成你自己的user名和ip地址。</p>\n<p><strong>【我在我自己电脑和服务器之间都配置了ssh免密码登录 直接使用ssh IP地址就可以登录了，强烈建议配置ssh，非常方便】</strong></p>\n<h4 id=\"登录远程主机执行单条命令\"><a href=\"#登录远程主机执行单条命令\"

那些前缀也可以，但是看着就恶心。这样我们就可以使用以下几个方案,原内容如下，我做了备注，这样比较一目了然。</p>\n<h4 id=\"登录远程主机执行多条命令\"><a href=\"#登录远程主机执行多条命令\" class=\"headerlink\" title=\"登录远程主机执行多条命令\"></a>登录远程主机执行多条命令</h4><p>\u000b<img

。</p>\n<h2 id=\"测试\"><a href=\"#测试\" class=\"headerlink\"
