Nginx + PHP部署
创建php容器，设置端口映射、目录映射
[root@ergeth23set3asr56erty45 ~]# docker run --name php-fpm -id -v ~/nginx/www:/usr/share/nginx/html php:7.4-fpm 命令说明：
- -d: 后台运行容器，并返回容器ID；
- --name php-fpm : 将容器命名为 php-fpm
- -v ~/nginx/www:/usr/share/nginx/html : 将主机中项目的目录 www 挂载到容器的 /usr/share/nginx/html
创建 ~/nginx/conf/conf.d 目录：
[root@ergeth23set3asr56erty45 ~]# mkdir ~/nginx/conf/conf.d
在该目录下添加 ~/nginx/conf/conf.d/runoob-test-php.conf 文件，内容如下：
server {
listen 80;
server_name localhost;
location / {
root /usr/share/nginx/html;
index index.html index.htm index.php;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location ~ \.php$ {
fastcgi_pass php:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html/$fastcgi_script_name;
include fastcgi_params;
}
}配置文件说明：
- php:9000: 表示 php-fpm 服务的 URL，下面我们会具体说明。
- /www/: 是 myphp-fpm 中 php 文件的存储路径，映射到本地的 ~/nginx/www 目录。
启动 nginx：
[root@ergeth23set3asr56erty45 ~]# docker run --name runoob-php-nginx -p 80:80 -d -v ~/nginx/www:/usr/share/nginx/html:ro -v ~/nginx/conf/conf.d:/etc/nginx/conf.d:ro nginx- -p 80:80: 端口映射，把 nginx 中的 80 映射到本地的 80 端口 ,格式为：主机(宿主)端口:容器端口, -p 80[主机端口]：80[ nginx容器端口]。
- ~/nginx/www: 是本地 html 文件的存储目录，/usr/share/nginx/html 是容器内 html 文件的存储目录。
- ~/nginx/conf/conf.d: 是本地 nginx 配置文件的存储目录，/etc/nginx/conf.d 是容器内 nginx 配置文件的存储目录。
- --link myphp-fpm:php: 把 myphp-fpm 的网络并入 nginx，并通过修改 nginx 的 /etc/hosts，把域名 php 映射成 127.0.0.1，让 nginx 通过 php:9000 访问 php-fpm。
接下来我们在 ~/nginx/www 目录下创建 index.php，代码如下：
浏览器打开 http://127.0.0.1:8083/index.php，显示如下：
