docker安装php-fpm,并与集成到nginx中

运行php-fpm容器：

docker run -d \
--name php-fpm \
-p 59000:9000 \
-v /home/docker/nginx/html:/var/www/html  \
php:7.3.5-fpm-alpine3.9 \
php-fpm

/home/docker/nginx/html是宿主机映射到nginx卷对应的目录。

找到nginx的默认配置文件conf.d/defautl.conf：

server {
    listen       80;
    server_name  localhost;
 
    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;
 
    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }
 
    #error_page  404              /404.html;
 
    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
 
    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}
 
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        root           /var/www/html/;
        fastcgi_pass   192.168.56.100:59000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
 
    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

注意：# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000之后的配置节被注释了，取消注释，并对配置作如下修改：

fastcgi_pass改为php-fpm的侦听地址和端口，这里192.168.56.100是宿主机的地址，59000是宿主机的映射端口，参看上面的容器运行指令。

fastcgi_param SCRIPT_FILENAME改为php-fpm容器内部存放web文件的目录+脚本文件名，这里是/var/www/html/$fastcgi_script_name，注意/var/www/html是php-fpm容器内对应的web文件存放目录。
