源码安装，/configure 没有权限是什么问题

Directory and file names:
--prefix=PREFIX install architecture-independent files in PREFIX
--主安装目目录 [/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[same as prefix]
--bindir=DIR user executables in DIR [EPREFIX/bin]
--bin目录
--sbindir=DIR system admin executables in DIR [EPREFIX/sbin]
--sbin目录
--libexecdir=DIR program executables in DIR [EPREFIX/libexec]
--datadir=DIR read-only architecture-independent data in DIR
[PREFIX/share]
--sysconfdir=DIR read-only single-machine data in DIR [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data in DIR
[PREFIX/com]
--localstatedir=DIR modifiable single-machine data in DIR [PREFIX/var]
--libdir=DIR object code libraries in DIR [EPREFIX/lib]
--includedir=DIR C header files in DIR [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc in DIR [/usr/include]
--infodir=DIR info documentation in DIR [PREFIX/info]
--mandir=DIR man documentation in DIR [PREFIX/man]
--srcdir=DIR find the sources in DIR [configure dir or ..]
--program-prefix=PREFIX prepend PREFIX to installed program names
--program-suffix=SUFFIX append SUFFIX to installed program names
--program-transform-name=PROGRAM
run sed PROGRAM on installed program names

些参数具体意思意思
面帮助文档
--bindir=DIR user executables in DIR [EPREFIX/bin]
1.默认bin目录哪bin
--sbindir=DIR system admin executables in DIR [EPREFIX/sbin]
2.默认sbin目录哪sbin
3.EPREFIXPREFIX区别致意思相路径绝路径

问问题要求linux 系统搭建两套Apache+mysql+php环境
Apachemysql都搞定剩PHP
4.知道PHP安装路径哪些目录公用些必须区
注意我说两套环境完全用源码包安装两套说两Apache目录及配置文件同mysql（包括数据库目录配置文件路径等等）剩PHP装两套貌似些默认目录公用放着比php.ini文件默认放/usr/local/bin面现两套系统所放路径懂我意思
