1.安装nginx

[python]

1. yum install yum-priorities -y  
2. wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm  
3. rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm  
4. yum install nginx
   

1. systemctl start nginx.service #启动nginx  
2. systemctl stop nginx.service #停止  
3. systemctl restart nginx.service #重启  
4. systemctl enable nginx.service #设置开机启动  
   

2.更改nginx端口号（根据自己需求）

1. cd /etc/nginx/conf.d/  
2. vim default.conf  
3. 把listen 80改成listen 81 
4. systemctl restart nginx.service #重启nginx 
   

3.访问http://ip:81即可看到nginx首页

4.下一步安装php-fpm

           yum install php-fpm 

1. systemctl start php-fpm.service #启动php-fpm  
2. systemctl enable php-fpm.service #设置开机启动 
   

5.更改nginx配置文件识别php vi /etc/nginx/conf.d/default.conf，把之前的#给去掉就可以了，顺手改一下fastcgi_param

      location ~ \.php$ {

                                        root           html;

                                       fastcgi_pass   127.0.0.1:9000;   

                                       fastcgi_index  index.php;  

                                      fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html/$fastcgi_script_name; 

                                      include        fastcgi_params;

                                  } 

6.

在 /usr/share/nginx/html中新建一个test.PHP  <?php echo 123;?>

访问http://ip:81/test.php即可看到php页面

7.负载配置   

               upstream site{  

                                     server 172.16.170.138;

                                     server 172.16.170.139; 

                                      }

                server { 

                                   listen       80;

                                  server_name  localhost; 

                                  #charset koi8-r;  

                                 #access_log  /var/log/nginx/log/host.access.log  main;  

                location / {  

                                root   /usr/share/nginx/html;

                                index  index.html index.htm; 

                                proxy_pass http://site; 

                                 }
