之前的时候写过Centos yum 安装nginx 后增加模块,源码安装的时候一笔带过，最近在学习Nginx其中的一些知识点，所以记录一下手动安装的过程，以及相关的配置。

安装

Nginx 一般可以去官网下载，Nginx,Nginx也有对应的商业版本Nginx Plus, 还有一些其他的基于Nginx开发的版本，Tengine和OpenResty都是比较有名的。

下载

Nginx下载,如下图，进入到下载页面，使用stable version稳定版。

从上面的帮助可以看到，主要的编译配置分为3类

  • 配置文件位置指定
  • 指定使用和不使用的模块with（增加编译）、without（移除编译）
  • 优化参数、第三方模块，日志位置等

#编译,指定位置
./configure --prefix=/home/nginx

可能会出现报错

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

根据提示，可以安装对应的库，或者在编译的时候选择移除对应的模块，或者选择从源码编译

#安装 pcre library
yum -y install pcre-devel

再次编译提示缺少 zlib

./configure: error: the HTTP gzip module requires the zlib library.

编译生成了中间文件 objs,通过查看ngx_modules.c,可以知道nginx编译了哪些模块
执行make编译make install 安装
安装完成进入 /home/nginx/启动nginx以后

在生产环境中，要根据实际的情况增加第三方模块
