如何进行Centos 7.3 x64安装nginx与反向代理的应用，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。

Centos 7.3 x64安装nginx-1.13.1

一、安装必要所需环境：

# yum install autoconf automake gcc gcc-c++ libtool make pkgconfig zlib-devel

# yum install pcre pcre-devel php-devel httpd-devel

# yum install zlib zlib-devel

# yum install openssl openssl-devel

#  groupadd nginx

#  useradd -g nginx nginx

#  mkdir /software

#  cd /software

# wget http://nginx.org/download/nginx-1.13.1.tar.gz

# tar xzf nginx-1.13.1.tar.gz

# cd nginx-1.13.1

安装相关依赖包

[root@ns1 nginx-1.13.1]#  yum install libxml2-devel libxslt-devel gd-devel

[root@ns1 nginx-1.13.1]#  yum install perl perl-devel perl-ExtUtils-Embed  libatomic_ops-devel

[root@ns1 nginx-1.13.1]# ./configure --user=nginx --group=nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --with-select_module --with-poll_module --with-file-aio --with-ipv6 --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_p_w_picpath_filter_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_auth_request_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_stub_status_module --with-http_perl_module --with-mail --with-mail_ssl_module --with-cpp_test_module  --with-cpu-opt=CPU --with-pcre  --with-pcre-jit  --with-zlib-asm=CPU --with-libatomic --with-debug --with-ld-opt="-Wl,-E" --http-client-body-temp-path=/var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi --http-scgi-temp-path=/var/tmp/nginx/scgi

[root@ns1 nginx-1.13.1]#

将启动脚本（见附件）上传到/etc/init.d/ 目录下面

# chmod +x /etc/init.d/nginx

# chkconfig --add nginx

# chkconfig nginx on

# chkconfig --list nginx

# mkdir -p /var/tmp/nginx/client

编辑配置文件，红色字体为修改或添加后的项目

  #   location / {

  #     root  html;

  #     index  index.html index.htm;

  #   }

  #}

}

检测配置文件是否有语法错误

[root@host-cn tmp]# nginx -t -c  /etc/nginx/nginx.conf

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

加入防火墙允许

[root@ns1 nginx]# firewall-cmd --add-service=http --permanent

[root@ns1 nginx]# firewall-cmd --reload

[root@ns1 nginx]# systemctl restart firewalld

启动nginx服务

[root@ns1 nginx]# service nginx start

再用户就可以使用IP 110.110.220.54直接访问网站了。

反向代理的应用

公司同事，用tomcat发布了2个项目，可以用IP访问他的项目

A项目地址  http://110.110.220.54:8080/dy/jsp/index.jsp

B项目地址  http://110.110.220.54:8080/dy/position/login.jsp

现在使用nginx，用公司域名www.dongying.com来发布他的项目，方法如下：

绿色部分为项目A，设定正常后用www.dongying.com来访问。

橙色部分为项目B，设定正常后用www.dongying.com:8080/dy/position/login.jsp来访问。

  server {

listen 80;

server_name www.dongying.com;

charset utf-8;

   location / {

      proxy_pass http://www.dongying.com:8080/dgmy/jsp/;

      index index.html index.htm index.jsp login.jsp;

         }

  location ~ \.(gif|jpg|jpeg|png|bmp|swf|css|js)$

        {

          access_log off;

          expires 1d;

          root /opt/tomcat/webapps/dy/;

          break;

      }

 location /dy/position/ {

      proxy_pass http://www.dongying.com:8080/dy/position/login.jsp;

      proxy_set_header      Host $host;

      proxy_set_header  X-Real-IP  $remote_addr;

      proxy_set_header      X-Forwarded-For $proxy_add_x_forwarded_for;

      client_max_body_size  100m;

      root  html;

      index  index.html index.htm index.jsp login.jsp;

    }
