安装nvm之后，我怎么才能重新启动ssh会话呢？

nvm要求用户在安装后注销/返回以使更改生效。 我怎么能让这个在通过stream浪汉运行的任务中实现呢？ 这是我的尝试：

- name : Install nvm shell: curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.30.1/install.sh | bash failed_when: False register: nvm_installed - name: Kill open ssh sessions - ansible should log back in on next task shell: "ps -ef | grep sshd | grep `whoami` | awk '{print \"kill -9\", $2}' | sh" when: nvm_installed | changed failed_when: false - name : Install Node.js v 4.2.x command : nvm install v4.2 

但是我得到的错误：

 fatal: [default] => SSH Error: ssh_exchange_identification: Connection closed by remote host while connecting to 127.0.0.1:2222 It is sometimes useful to re-run the command using -vvvv, which prints SSH debug output to help diagnose the issue. TASK: [check if rpmforge installed] ******************************************* FATAL: no hosts matched or all hosts have already failed -- aborting 

命令vagrant ssh现在也失败，错误：

 ssh_exchange_identification: Connection closed by remote host 

我基于这里给出的答案 – https://stackoverflow.com/questions/26677064/create-and-use-group-without-restart

• testing厨房没有检测到winrm，并使用SSH客户端
• OS Xnetworking堆栈忽略IGMP成员身份查询
• ffmpeg继续监听端口
• 如何限制对在Exchange 2010中具有完整邮箱权限的用户的访问？
• 如何将脚本变成守护进程？ 所以在一个随机的脚本失败后，内核会重启它？

我想也许kill命令是杀死sshd守护进程本身？

 ps -ef | grep sshd | grep `whoami` root 2621 1247 0 11:30 ? 00:00:00 sshd: vagrant [priv] vagrant 2625 2621 0 11:30 ? 00:00:00 sshd: vagrant@notty root 3232 1247 4 11:34 ? 00:00:00 sshd: vagrant [priv] vagrant 3235 3232 0 11:34 ? 00:00:00 sshd: vagrant@pts/0 vagrant 3252 3236 0 11:34 pts/0 00:00:00 grep sshd 

UPDATE

我也尝试了以下内容：

 - name : Install nvm shell: "curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.30.1/install.sh | bash" register: nvm_installed failed_when: False - name : source bash profiles shell : source /home/vagrant/.bashrc when: nvm_installed register: sourced - name : Install Node.js v 4.2.x command : nvm install v4.2 when: sourced 

但得到以下错误：

 TASK: [Install Node.js v 4.2.x] *********************************************** failed: [default] => {"cmd": "nvm install v4.2", "failed": true, "rc": 2} msg: [Errno 2] No such file or directory FATAL: all hosts have already failed -- aborting PLAY RECAP ******************************************************************** to retry, use: --limit @/Users/lukemackenzie/playbook.retry default : ok=10 changed=3 unreachable=0 failed=1 Ansible failed to complete successfully. Any error output should be visible above. Please fix these errors and try again. 

如果我在托pipe机器上手动运行安装nvm步骤，则说明以下内容已被添加到.bashrc ：

 export NVM_DIR="/home/vagrant/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
