CentOS 7服务器下Nginx安装配置

1、安装编译工具及库文件

$ yum -y install make zlib zlib-devel gcc gcc-c++ libtool  openssl openssl-devel pcre pcre-devel  //PCRE 做用是让 Nginx 支持 Rewrite 功能

2、安装Nginx

一、下载Nginx至文件夹/usr/local内

$ cd /usr/local/     //进入目标目录
$ wget http://nginx.org/download/nginx-1.14.2.tar.gz  //下载nginx,选择稳定版本

二、解压缩文件包

$ tar zxvf nginx-1.14.2.tar.gz

三、进入安装目录，编译安装

$ cd nginx-1.14.2
$ ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-pcre  --with-http_ssl_module
$ make
$ make install

安装完成后的摘要信息：

Configuration summary
  + using system PCRE library
  + using system OpenSSL library
  + 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"

默认安装到/usr/local/nginx目录。

四、查看Nginx版本

$ /usr/local/nginx/sbin/nginx -v

输出结果以下：
nginx version: nginx/1.14.2
到此，nginx安装完成。

五、启动、关闭Nginx

检查配置文件是否正确

$ /usr/local/nginx/sbin/nginx -t
$ /usr/local/nginx/sbin/nginx -V     //能够看到编译选项

启动Nginx

$ /usr/local/nginx/sbin/nginx     // 启动
$ /usr/local/nginx/conf/nginx.conf  //配置文件

从新载入配置文件

$ /usr/local/nginx/sbin/nginx -s reload

重启Nginx，不会改变启动时指定的配置文件

$ /usr/local/nginx/sbin/nginx -s reopen

中止Nginx

$ /usr/local/nginx/sbin/nginx -s stop

或

$ pkill nginx

3、Nginx配置

具体配置可搜索，这里不作介绍
配置文件nginx.conf,位置
/usr/local/nginx/conf/nginx.conf

4、防火墙配置

CentOS7默认的防火墙为firewall
开启端口80方法：

$ firewall-cmd --zone=public --add-port=80/tcp --permanent  //--permanent永久生效，没有此参数重启后失效
$ firewall-cmd --reload  //从新载入
$ firewall-cmd --zone=public --query-port=80/tcp  //查看
//$ firewall-cmd --permanent --query-port=80/tcp //或者这样查看
$ firewall-cmd --zone=public --remove-port=80/tcp --permanent  //删除端口
