centos cannot find the php command what to do?

-bash: php: command not found Command not found

This problem is actually very simple. If you enter a command in the terminal and the system prompts If you say Command not found, it is either because you have not installed the corresponding software package, or because of a path setting problem. If it is because of a software package problem, there is nothing else to say, just install the corresponding software package. In another case, the user's path needs to be set.

-bash: ls: command not found 或者 -bash: ll: command not found

Cause: When setting environment variables, the editing profile file was not written correctly, resulting in commands such as ls not being recognized on the command line.

Solution:

export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
bash: PHP: command not found

Solution:

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

Then, echo $PATH and see, you will see it.

usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/php/bin

At this time, you can directly type php -i in any directory of the system to execute it.

-bash:unzip: command not found

Download the RPM package of wget: http://mirrors.163.com/centos/6.2/os/x86_64/Packages/wget-1.12-1.4.el6.x86_64.rpm

rpm ivh wget-1.12-1.4.el6.x86_64.rpm Just install it.

2. yum installation

yum -y install wget
