个人安装php开发环境心得——nginx安装篇

1. 安装wget为了使用wget下载nginx 先安装wget，在configure时需要加上ssl参数，如下：
./configure --with-ssl=openssl
否则会报错，configure: error: –with-ssl was given, but GNUTLS is not available.
2. 下载nginxnginx最初下载的是1.2.4版。安装nginx前需要安装pcre，下载pcre 8.20，安装后开始./configure nginx, 在make阶段曝出如下错误：

objs/ngx_modules.o \
-lpcre -lssl -lcrypto -lz
Undefined symbols for architecture x86_64:
"_pcre_free_study", referenced from:
_ngx_pcre_free_studies in ngx_regex.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
make[1]: * [objs/nginx] Error 1
make: * [build] Error 2

3. 安装macports查找文档得知应该是安装pcre出错，官方文档建议：
Undefined symbols for architecture x86_64: "_pcre_free_study", referenced from: _ngx_pcre_free_studies in ngx_regex.o

在Nginx官方的问题列表里面有这个问题的具体描述，详细请看这里compilation fails on Mac OS X 10.7.2，其实就是库的位置没有找到。
1. Remove the PCRE version installed into /usr/local and reinstall one from macports. This is recommended solution.
2. Force /usr/local/lib to be before /usr/lib in library search path with ./configure --with-ld-opt="-I /usr/local/lib". This may work, but likely you'll be facing the same problem in other places as well.
具体过程首先安装macports，然后利用port安装pcre。安装macports可以编译源码，也可以直接使用dmg安装。Installing MacPorts上有详细的安装说明。安装pcre就很简单了，一行命令。
据此选用方案1, 下载macports，安装完成后，输入port install pcre，提示sudo：port：command not found，说明没有配置port的$PATH
在命令行下输入echo $PATH
显示：/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
到Shell下查看~/.profile文件，会发现MacPorts在安装时已经把环境变量写入到该文件中了
在命令行下输入
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
或者将该profile导入/etc/profiles文件中，port命令即可使用
输入port install pcre
Error: Insufficient privileges to write to MacPorts install prefix.
说明没有root权限
sudo port install pcre即可
安装完成后试图编译nginx，仍然提示出错，去官网查询，显示地址：http://trac.nginx.org/nginx/ticket/161
Downloading 1.0.15 and building yields a successful install.
将ngix版本退回1.0.15 重新./configure make & make install 安装完成。
