现在，我们安装了所有必需的组件。唯一的配置更改我们仍然需要做的是告诉Nginx使用我们的PHP处理器的动态内容。我们在服务器块级别上执行此操作（服务器块类似于Apache的虚拟主机）。
一、修改nginx.conf
whereis nginx搜索nginx
[root@localhost~]# whereis nginx
nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx /usr/share/man/man3/nginx.3pm.gz /usr/share/man/man8/nginx.8.gz
[root@localhost ~]# cd /etc/nginx
[root@localhost nginx]# ls
conf.d fastcgi.conf fastcgi_params koi-utf mime.types nginx.conf scgi_params uwsgi_params win-utf
default.d fastcgi.conf.default fastcgi_params.default koi-win mime.types.default nginx.conf.default scgi_params.default uwsgi_params.default
[root@localhost nginx]# vim nginx.conf
vi nginx.conf打开配置
以下配置文件中，被>>><<<标注的地方，为必须要更改的地方，如下5点
[root@localhost nginx]# vi nginx.conf
# For more information on configuration, see:
# * Official English Documentation: http://nginx.org/en/docs/
# * Official Russian Documentation: http://nginx.org/ru/docs/
user root; 1. >>>改成有权限的自定义账户，也可以是root<<< 【可暂时不改】
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;

keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf;
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name xxx; 2. >>>自定义服务名称<<< 【可暂时不改】
root /***/***/***; 3. >>>项目根目录地址<<< 【可暂时不改】
index index.php index.html; 4. >>>必须新增这一行，不然报403<<< 【可暂时不改】
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
}
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 5. 直接复制如下代码块，在server { } 模块里，表示动态访问php 【必须添加】
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
# Settings for a TLS enabled server.
#
# server {

# listen [::]:443 ssl http2 default_server;
# server_name _;

#
# ssl_certificate "/etc/pki/nginx/server.crt";
# ssl_certificate_key "/etc/pki/nginx/private/server.key";
# ssl_session_cache shared:SSL:1m;

# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
#
# # Load configuration files for the default server block.
# include /etc/nginx/default.d/*.conf;
#

#
# error_page 404 /404.html;
# location = /40x.html {
# }
#
# error_page 500 502 503 504 /50x.html;
# location = /50x.html {
# }
# }
}
ps aux | grep "nginx:worker process" | awk '{print $1}'查看nginx账户，本文直接使用root
[root@localhost ~]# ps aux | grep "nginx:worker process" | awk '{print $1}'
root
vim保存退出 ，建议查看是否修改成功，然后重启nginx
二、重启Nginx
注意~~~修改了配置文件后，最好检查下修改过的配置文件是否正确，以免重启后Nginx出现错误，影响服务器稳定运行。
nginx -t -c /xxx/xxx/nginx.conf检查Nginx配置是否正确
[root@localhost ~]# 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
nginx -s reload重启，有错误会报错，没错误表明重启成功
[root@localhost ~]# nginx -s reload
[root@localhost ~]#
当然也可以kill进程，然后重新启动
[root@localhost ~]# ps -ef | grep nginx
root 14136 1 0 09:24 ? 00:00:00 nginx: master process nginx -c /etc/nginx/nginx.conf
root 14242 14192 0 10:29 pts/1 00:00:00 tail -f /var/log/nginx/error.log
root 14661 14136 0 14:35 ? 00:00:00 nginx: worker process
root 14698 14021 0 14:38 pts/0 00:00:00 grep --color=auto nginx
[root@localhost ~]# kill 14136
[root@localhost ~]# ps -ef | grep nginx
root 14242 14192 0 10:29 pts/1 00:00:00 tail -f /var/log/nginx/error.log
root 14700 14021 0 14:38 pts/0 00:00:00 grep --color=auto nginx
[root@localhost ~]# nginx -c /etc/nginx/nginx.conf
[root@localhost ~]# ps -ef | grep nginx
root 14242 14192 0 10:29 pts/1 00:00:00 tail -f /var/log/nginx/error.log
root 14702 1 0 14:39 ? 00:00:00 nginx: master process nginx -c /etc/nginx/nginx.conf
root 14703 14702 0 14:39 ? 00:00:00 nginx: worker process
root 14709 14021 0 14:39 pts/0 00:00:00 grep --color=auto nginx
三、Web服务器上测试PHP处理
在/usr/share/nginx/html下面，新建test.php文件
[root@localhost ~]# vi /usr/share/nginx/html/test.php
输入如下php代码。
<?php phpinfo(); ?>
查看
[root@localhost ~]# cd /usr/share/nginx
[root@localhost nginx]# ll
total 8
drwxr-xr-x 2 root root 4096 Oct 8 15:25 html
drwxr-xr-x 2 root root 4096 Sep 26 14:56 modules
[root@localhost nginx]# cd html
[root@localhost html]# ls
404.html 50x.html index.html nginx-logo.png poweredby.png test.php
测试，配置正确，如下图
