CentOS出現：bash: apxs: command not found 的解決方法

出現錯誤訊息 bash: apxs: command not found 是因為你的 Centos系统是最简单安装，并没有自带apxs，所以你要补充安装。

登录SSH：
yum install httpd-devel.x86_64

若你是 32bits CPU, 請用

yum install httpd-devel.i686

apxs is an Apachec extension tool.

I realize that this tool, is by default, not installed under CentOS (or perhaps even RedHat).
To fix this, just install it using yum by:

yum install httpd-devel.i386
where apxs is installed under "httpd-devel" package.
