nginx 安装错误信息解决

可能出现错误在配置信息./configure --prefix=/usr/local/nginx 的时，出现错误：
/configure: error: the HTTP rewrite module requires the PCRE library.
解决方法：安装pcre
yum -y install pcre pcre-devel
-y 是跳过所有需要手动确认的环节
缺少ssl错误，错误信息如下：
./configure: error: the HTTP cache module requires md5 functions
from OpenSSL library. You can either disable the module by using
--without-http-cache option, or install the OpenSSL library into the system,
or build the OpenSSL library statically from the source with nginx by using
--with-http_ssl_module --with-openssl=<path> options.
解决方法：安装openssl
yum -y install openssl openssl-devel
缺少编译器，错误信息如下：
./configure: error: C compiler cc is not found
解决方法：安装gcc-c++
yum -y install gcc-c++ autoconf automake
autoconf是自动配置，automake是自动编译
缺少zlib包，错误信息如下：
./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using –without-http_gzip_module
option, or install the zlib library into the system, or build the zlib
library
statically from the source with nginx by using –with-zlib=<path> option.
解决方法：安装zlib
yum install -y zlib-devel
确实libxml2，错误信息如下：
./configure: error: the HTTP XSLT module requires the libxml2/libxslt
libraries. You can either do not enable the module or install the libraries.
解决方法：
yum -y install libxml2 libxml2-dev
yum -y install libxslt-devel
http_image_filter_module是nginx提供的集成图片处理模块，需要gd-devel的支持，错误信息如下：
./configure: error: the HTTP image filter module requires the GD library.
You can either do not enable the module or install the libraries.
解决方法：
yum -y install gd-devel
缺少ExtUtils，错误信息如下：
./configure: error: perl module ExtUtils::Embed is required
解决方法：
yum -y install perl-devel perl-ExtUtils-Embed
缺少GeoIP，错误信息如下：
./configure: error: the GeoIP module requires the GeoIP library.
You can either do not enable the module or install the library.
解决方法：
yum -y install GeoIP GeoIP-devel GeoIP-data
安装完成后启动安装成功后 /usr/local/nginx 目录下如下
fastcgi.conf koi-win nginx.conf.default
fastcgi.conf.default logs scgi_params
fastcgi_params mime.types scgi_params.default
fastcgi_params.default mime.types.default uwsgi_params
html nginx uwsgi_params.default
koi-utf nginx.conf win-utf
启动
确保系统的 80 端口没被其他程序占用，运行/usr/local/nginx/nginx 命令来启动 Nginx，
netstat -ano|grep 80
如果查不到结果后执行，有结果则忽略此步骤（ubuntu下必须用sudo启动，不然只能在前台运行）
sudo /usr/local/nginx/nginx
打开浏览器访问此机器的 IP，如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。
