如何查看CentOS下nginx、apache、mysql和php的编译参数？
在升级nginx、apache、mysql和php的版本时，我们经常需要知道nginx、apache、mysql和php之前的编译参数是什么，以确保在升级过程中编译参数一致。这里我们将详细讲解nginx、apache、mysql、php源码编译的软件参数查看方法。
nginx编译参考：
[root@localhost]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.10.0

configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-ipv6
apache编译参考：
[root@localhost]#cat /usr/local/apache/build/config.nice
#! /bin/sh
#

"./configure"
"--prefix=/usr/local/httpd"
"--with-apr=/usr/local/apr"
"--with-apr-util=/usr/local/apr-util"
"--with-pcre"
"--with-mpm=event"
"--enable-rewrite"
"--enable-proxy"
"--with-z"
"--enable-so"
"$@"
mysql编译参考：
[root@localhost]# cat /usr/local/mysql/bin/mysqlbug | grep configure
# This is set by configure

php编译参考：
[root@localhost]# /usr/local/php/bin/php -i |grep configure
