软件安装好了，想查看当初编译时的参数，怎么搞？
1、Nginx，可以通过 -V 参数查看Nginx版本及编译参数
/usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.10.2
built by gcc 4.4.6 20110731 (Red Hat 4.4.6-4) (GCC)
configure arguments: –prefix=/usr/local/nginx/ –with-http_image_filter_module –with-http_gunzip_module –with-http_gzip_static_module –with-http_dav_module –with-http_auth_request_module –with-http_secure_link_module –with-http_slice_module –with-http_stub_status_module –with-stream –with-pcre=/usr/local/tools/pcre-8.38 –with-zlib=/usr/local/tools/zlib-1.2.8
2、Apache，编译参数存放在 apache 的 config.nice 文件，前提时，没有做过 make clean
locate config.nice | grep apache | xargs cat
#! /bin/sh
#
# Created by configure“./configure” \
“–with-apr=/usr/local/apr/” \
“–with-apr-util=/usr/local/apr-util/” \
“–with-pcre=/usr/local/pcre/” \
“ap_cv_void_ptr_lt_long=no” \
“–enable-proxy” \
“–enable-proxy-connect” \
“–enable-proxy-ftp” \
“–enable-proxy-http” \
“–enable-proxy-scgi” \
“–enable-proxy-ajp” \
“–enable-proxy-balancer” \
“$@”
3、MySQL，利用 msyqlbug 工具，查看MySQL信息
VISUAL=vim; export VISUAL; mysqlbug

4、PHP，可以通过 -i 参数可以打印PHP全局变量和安装信息
/usr/bin/php -i | grep configure
Configure Command => ‘./configure’ ‘–prefix=/usr/local/php/’ ‘–enable-fpm’ ‘–enable-opcache’ ‘–enable-inline-optimization’ ‘–with-libxml-dir=/usr/local/libxml2/’ ‘–with-curl=/usr/local/curl/’ ‘–enable-dba’ ‘–with-gd’ ‘–enable-gd-native-ttf’ ‘–enable-gd-jis-conv’ ‘–with-jpeg-dir=/usr/local/jpeg/’ ‘–with-png-dir=/usr/local/libpng/’ ‘–with-zlib-dir=/usr/local/zlib/’ ‘–with-freetype-dir=/usr/local/freetype/’ ‘–with-pcre-regex=/usr/local/pcre/’ ‘–with-pcre-jit’ ‘–with-pcre-dir=/usr/local/pcre/’ ‘–enable-mbstring’ ‘–enable-pcntl’ ‘–enable-soap’ ‘–enable-shmop’ ‘–enable-sockets’ ‘–enable-sysvsem’ ‘–enable-zip’ ‘–enable-mysqlnd’ ‘–with-mysqli=mysqlnd’ ‘–with-pdo-mysql=mysqlnd’
