-bash: centos: command not found

-bash: centos: command not found是由于系统无法找到centos命令引起的。这种情况通常是由于环境变量PATH设置不正确导致的。您可以尝试以下解决办法：

1. 在命令行中输入export PATH=/bin:/usr/bin:$PATH来修改环境变量PATH。这样可以暂时解决问题。请注意，这种方法只在当前会话中有效，关闭终端后需要重新设置。

2. 您还可以检查是否在/etc/profile文件中设置了错误的PATH属性。您可以通过在命令行中输入vi /etc/profile来查看和编辑该文件。确保PATH设置正确，例如export PATH=$PATH:/usr/java1.8/bin:/usr/java1.8/jre/bin。

3. 最后，关闭终端并重新打开，然后尝试执行命令。这样应该能够解决问题。

centos：-bash: redis: command not found

根据提供的引用内容，出现-bash: redis: command not found错误的原因是redis-server命令没有被正确安装或者环境变量没有被正确设置。解决方案如下：

1. 确认redis-server是否已经正确安装，可以通过执行以下命令进行确认：

whereis redis-server

如果输出结果中没有redis-server，则需要重新安装redis。

2. 如果redis-server已经正确安装，可以尝试通过以下命令添加redis-server命令的路径到环境变量中：

export PATH=/usr/local/bin:$PATH

其中/usr/local/bin是redis-server命令所在的路径，可以根据实际情况进行修改。

3. 如果以上两种方法都无法解决问题，可以尝试重新编译安装redis，并执行make install命令进行安装。

centos -bash: service: command not found

As an AI language model, I don't have access to the environment or server you are using. However, the error message "command not found" usually indicates that the command or utility you are trying to use is not installed on your system, or it is not included in your system's PATH environment variable.

To resolve this issue, you can try installing the missing command or utility using the package manager available on your system. For CentOS, you can use the yum package manager to install the missing utility. For example, if you are trying to use the "service" command, you can install it by running the following command as the root user:

sudo yum install -y systemd

This will install the systemd package, which provides the "service" command on CentOS. Once the installation is complete, you should be able to use the "service" command without any issues.
