nginx安装

前言：

Nginx是一个异步框架的Web服务器，也可以用作反向代理，负载平衡器 和 HTTP缓存。该软件由Igor Sysoev 创建，并于2004年首次公开发布。 同名公司成立于2011年，以提供支持。 Nginx是一款免费的开源软件，根据类BSD许可证的条款发布。

安装编译工具、依赖包

[root@Mike-VM-Node-172_31_225_214 ~]#  yum -y install gcc gcc-c++ autoconf automake make zlib zlib-devel openssl openssl-devel pcre pcre-devel wget vim tar curl gd-devel

以上安装的是一些主要的依赖包，具体可根据自己情况或者报错信息提示安装或修改

创建用户和组

[root@Mike-VM-Node-172_31_225_214 ~]# useradd -M -s /sbin/nologin nginx

新建的用户组和用户主要是在编译配置的时候指定nginx运行的用户和用户组,这样指定后以后配置使用也方便

下载解压nginx

[root@Mike-VM-Node-172_31_225_214 ~]# cd /usr/local/
[root@Mike-VM-Node-172_31_225_214 /usr/local]# wget http://nginx.org/download/nginx-1.18.0.tar.gz
[root@Mike-VM-Node-172_31_225_214 /usr/local]# tar zxvf nginx-1.18.0.tar.gz 
[root@Mike-VM-Node-172_31_225_214 /usr/local]# rm -rf nginx-1.18.0.tar.gz

编译安装

[root@Mike-VM-Node-172_31_225_214 /usr/local]# cd nginx-1.18.0/
[root@Mike-VM-Node-172_31_225_214 /usr/local/nginx-1.18.0]# ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_v2_module --with-http_gzip_static_module --with-http_sub_module  --with-http_realip_module --with-http_image_filter_module --with-stream
[root@Mike-VM-Node-172_31_225_214 /usr/local/nginx-1.18.0]# make && make install

添加环境变量

[root@Mike-VM-Node-172_31_225_214 /usr/local/nginx-1.18.0]# ln -sv /usr/local/nginx/sbin/nginx /usr/local/sbin

设置 systemctl 脚本启动

[root@Mike-VM-Node-172_31_225_214 /usr/local/nginx-1.18.0]# cd 
[root@Mike-VM-Node-172_31_225_214 ~]# vim /usr/lib/systemd/system/nginx.service

[root@Mike-VM-Node-172_31_225_214 ~]#

启动 NGINX和添加防火墙 80 443 端口

[root@Mike-VM-Node-172_31_225_214 ~]# systemctl start nginx
[root@Mike-VM-Node-172_31_225_214 ~]# firewall-cmd --zone=public --add-port=80/tcp --permanent
[root@Mike-VM-Node-172_31_225_214 ~]# firewall-cmd --zone=public --add-port=443/tcp --permanent
[root@Mike-VM-Node-172_31_225_214 ~]# firewall-cmd --reload

如果iptables防火墙
[root@Mike-VM-Node-172_31_225_214 ~]# vim /etc/sysconfig/iptables

-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 443 -j ACCEPT

[root@Mike-VM-Node-172_31_225_214 ~]# systemctl restart iptables

修改nginx默认主配置文件

[root@Mike-VM-Node-172_31_225_214 ~]#

默认80端口已经被我重定向到百度首页，创建网站站点需要新建虚拟文件如下

[root@Mike-VM-Node-172_31_225_214 /usr/local/nginx/conf]# mkdir conf.d

如果有使用PHP代码是这样配置，如下

[root@Mike-VM-Node-172_31_225_214 /usr/local/nginx/conf/conf.d]# vim php.conf

server
    {
        listen 80;

        index index.html index.php index.htm default.html default.htm default.php;
        root  /www/nginx/html;

         error_log  /data/logs/nginx_log/php.com/error.log;
         access_log  /data/logs/nginx_logs/php.com/access.log;
        
        
       location ~ [^/]\.php(/|$)
        {

            fastcgi_pass  127.0.0.1:9000;
            fastcgi_index index.php;
            include fastcgi.conf;
        set $real_script_name $fastcgi_script_name;
        if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
        set $real_script_name $1;
        set $path_info $2;
       }
      fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
      fastcgi_param SCRIPT_NAME $real_script_name;
      fastcgi_param PATH_INFO $path_info;
      }

        location ~* \.(eot|otf|ttf|woff|woff2|svg)$ {
        add_header Access-Control-Allow-Origin *;
        }


        location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
        {
            expires      30d;
        }

        location ~ .*\.(js|css)?$
        {
            expires      12h;
        }

        location ~ /.well-known {
            allow all;
        }

        location ~ /\.

        }


    }

主配置文件下要把PHP虚拟配置注释打开（nginx.conf）不然不生效哦！！！！
