# Linux镜像安装一键式重置密码插件启动失败怎么办？
#### 操作场景
Linux镜像安装一键式重置密码插件启动失败，请参考本章节处理。
#### 问题描述
用户通过执行命令**sudo sh setup.sh**安装一键式重置密码插件，有如下报错：
```
begin install CloudResetPwdAgent
===============cp LinuxCloudResetPwdAgent======================
===============vi /etc/profile======================
===============begin install CloudrResetPwdAgent===================
Detected RHEL or Fedora:
Installing the cloudResetPwdAgent daemon using systemd...
creating default service file...
Reading file /etc/systemd/system/cloudResetPwdAgent.service
Job for cloudResetPwdAgent.service failed because the control process exited with error code.
See "systemctl status cloudResetPwdAgent.service" and "journalctl -xe" for details.
Failed to start service cloudResetPwdAgent
/CloudResetPwdAgent/CloudResetPwdAgent.Linux
cloudResetPwdAgent install successfully.
```
同时/var/log/message文件中有如下报错：
```
systemd[1]: Starting cloudResetPwdAgent...
systemd[2324]: cloudResetPwdAgent.service: Failed to execute command: Permission denied
systemd[2324]: cloudResetPwdAgent.service: Failed at step EXEC spawning /CloudrResetPwdAgent/bin/./cloudResetPwdAgent.script: Permission denied
systemd[1]: cloudResetPwdAgent.service: Control process exited, code=exited status=203
systemd[1]: cloudResetPwdAgent.service: Failed with result 'exit-code'.
systemd[1]: Failed to start cloudResetPwdAgent.
```
则由于SELinux开启时，重置密码插件不能在根目录下执行，需要关闭SELinux。
#### 处理方法
1. 执行以下命令，临时关闭SELinux。 
   **setenforce 0**
   
   
2. 再次执行[关闭Selinux](https://support.huaweicloud.com/ecs_faq/ecs_faq_1209.html)操作，确保虚拟机重启后生效。
3. 执行以下命令，重新安装重置密码插件。 
   **sudo sh setup.sh**
   - 如果脚本执行成功打印"cloudResetPwdAgent install successfully."，且未打印"Failed to start service cloudResetPwdAgent"，表示安装成功。
   
   - 否则安装失败，请检查安装环境是否符合要求，并重试安装操作。
