MAC Osx PHP安装指导

php.ini的位置

Mac OS X中没有默认的php.ini文件，但是有对应的模版文件php.ini.default，位于/private/etc/php.ini.default 或者说 /etc/php.ini/default ，可以自行拷贝一份进行修改。

sudo cp /private/etc/php.ini.default /private/etc/php.ini

mac编译apache时出现 checking whether the C compiler works... no 的解决办法

在MAC下编译apache时执行 ./configure 出现如下错误。
checking for gcc... /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain/usr/bin/cc

checking whether the C compiler works... no
configure: error: in /Users/hufeiyan/ws/httpd-2.2.26': configure: error: C compiler cannot create executables See config.log' for more details

查看config.log有如下描述：(config.log文件在apache的文件夹下)

configure:4480: result: /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain/usr/bin/cc
configure:4709: checking for C compiler version

configure:4775: $? = 127
configure:4813: result: no

解决办法：

在命令行执行如下命令：

sudo ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/ /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain

其中/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/是固定写法，/Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain 可以在config.log中找到

如何解决:sorry,i cannot run apxs.possible reasons follow

.在编译安装php5.2的时候出现下面错误:sorry,i cannot run apxs.possible reasons follow:

Sorry, I cannot run apxs.  Possible reasons follow:

1. Perl is not installed
2. apxs was not found. Try to pass the path using --with-apxs2=/path/to/apxs
3. Apache was not built using --enable-so (the apxs usage page is displayed)

解决方法:根据英文提示我们可以看到如下几点:perl没有安装,指定正确的apxs路径

于是进行如下操作:

yum install perl* 之前是yum install perl

终端输入：find / -name apxs 得到的路径是:/usr/sbin/apxs

于是修改--with-apsx2=/usr/sbin/apxs指定到正确路径

最后正确执行

configure: error: xml2-config not found. Please check your&nb

安装php时的报错

checking libxml2 install dir... no
checking for xml2-config path...
configure: error: xml2-config not found. Please check your libxml2 installation.

安装完之后查找xml2-config文件是否存在
[root@XKWB3403 php-5.3.8]# find / -name "xml2-config"
/usr/bin/xml2-config

重新安装libxml2和libxml2-devel包

brew install libxml2

如果还是报错。就执行下边的命令：
首先进入php的安装文件的目录：

cd /path/php;
然后使用下边的命令：

./configure --with-libxml-dir=/usr/local/Cellar/libxml2/2.9.3/

没有特殊情况的话，会出现下边的成功提示：

Thank you for using PHP.

更新brew

调用brew update如果出现下边的错误：

Error: The /usr/local directory is not writable.
Even if this directory was writable when you installed Homebrew, other
software may change permissions on this directory. For example, upgrading
to OS X El Capitan has been known to do this. Some versions of the
"InstantOn" component of Airfoil or running Cocktail cleanup/optimizations
are known to do this as well.

You should probably change the ownership and permissions of /usr/local
back to your user account.
  sudo chown -R $(whoami):admin /usr/local

在终端中运行sudo chown -R $(whoami):admin /usr/local后，然后运行brew update.
