nginx安装

本文主要是介绍nginx安装，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

1 安装依赖库

yum install -y gcc gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel 

2 下载nginx

在nginx下载页面获取一个最新的稳定版本的下载链接，使用wget下载,然后解压缩

cd  /usr/local
wget http://nginx.org/download/nginx-1.20.2.tar.gz
tar -zxvf nginx-1.20.2.tar.gz

3 安装nginx

• ./configure
  检测系统中的环境，可以通过在 configure 后加上参数来对下一步编译进行控制，比如可以通过--prefix指定安装路径，--with-http_ssl_module添加ssl模块支持https，执行完会生成Makefile文件

–prefix 指定安装路径

./configure
...

Configuration summary
  + using system PCRE library
  + OpenSSL library is not used
  + using system zlib library

  nginx path prefix: "/usr/local/nginx"
  nginx binary file: "/usr/local/nginx/sbin/nginx"
  nginx modules path: "/usr/local/nginx/modules"
  nginx configuration prefix: "/usr/local/nginx/conf"
  nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
  nginx pid file: "/usr/local/nginx/logs/nginx.pid"
  nginx error log file: "/usr/local/nginx/logs/error.log"
  nginx http access log file: "/usr/local/nginx/logs/access.log"
  nginx http client request body temporary files: "client_body_temp"
  nginx http proxy temporary files: "proxy_temp"
  nginx http fastcgi temporary files: "fastcgi_temp"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

./configure --prefix=/usr/local/nginx20 --with-http_ssl_module
...
Configuration summary
  + using system PCRE library
  + using system OpenSSL library
  + using system zlib library

  nginx path prefix: "/usr/local/nginx20"
  nginx binary file: "/usr/local/nginx20/sbin/nginx"
  nginx modules path: "/usr/local/nginx20/modules"
  nginx configuration prefix: "/usr/local/nginx20/conf"
  nginx configuration file: "/usr/local/nginx20/conf/nginx.conf"
  nginx pid file: "/usr/local/nginx20/logs/nginx.pid"
  nginx error log file: "/usr/local/nginx20/logs/error.log"
  nginx http access log file: "/usr/local/nginx20/logs/access.log"
  nginx http client request body temporary files: "client_body_temp"
  nginx http proxy temporary files: "proxy_temp"
  nginx http fastcgi temporary files: "fastcgi_temp"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

• make && make install
  编译并且安装，安装完会在prefix路径生成指定文件夹

 make && make install

4 启动nginx

启动时可以先使用./nginx -t 检查nginx配置语法是否正确，使用./nginx启动，./nginx -s reload重启，./nginx -s stop停止服务

cd nginx20/sbin
./nginx

5 其他

nginx使用的过程中缺失模块，./nginx -V查看当前configure ，然后在当前配置基础上添加相应配置，make编译(不需要make install 安装) ，将obj文件夹中的nginx替换掉安装路径sbin中nginx文件。

./nginx -V
