1. 获取 nginx 镜像

docker search nginx
docker pull nginx

1. 使用nginx镜像开启 nginx 应用容器

docker run -d --name nginx -p 8080:80 -v /tmp:/usr/share/nginx/html docker.io/nginx

说明

1. -d 后台运行
2. --name 自定义容器名称
3. -p 8080:80 宿主机的8080 映射到容器的80端口
4. -v 宿主机 tmp 目录映射容器地址(nginx服务器项目默认路径)

在/tmp 目录下新建一个 index.html 里面打个 hello nginx
访问 127.0.0.1:8080 正确的情况下会出现该文件内容

1. 获取 php-fpm 镜像

docker search php-fpm
docker pull bitnami/php-fpm

4.运行 php-fpm

docker run -d -v /tmp:/usr/share/nginx/html --name php-fpm docker.io/bitnami/php-fpm

1. 查看 php-fpm IP

docker inspect php-fpm | grep "IPAddress"

1. 修改 nginx 配置文件 使他跟 php-fpm 关联起来

#copy 配置文件
docker cp nginx:/etc/nginx/conf.d/default.conf ./default.conf
vim ./default.conf
#copy 下面的
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 index.php;
    }
    #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           html;
        fastcgi_pass   172.17.0.2:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html/$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;
    #}
}
# 修改 fastcgi_pass   127.0.0.1:9000;  为：
# fastcgi_pass   172.17.0.2:9000;
# 其中 172.17.0.2 是 上面查看 IP 获取的 每次都不一样
#覆盖到 nginx
docker cp ./default.conf nginx:/etc/nginx/conf.d/default.conf
#重启 nginx
docker restart nginx

1. 新建 /tmp/index.php

<?php
    echo phpinfo();

1. 访问本地 127.0.0.1 即可
2. docker 常用命令

进入容器

docker exec -it nginx /bin/bash

复制容器内的配置到宿主机器

docker cp nginx:/etc/nginx/conf.d/default.conf ./default.conf

复制宿主机器文件到容器

docker cp ./default.conf myNginx:/etc/nginx/conf.d/default.conf

docker 重启容器

docker restart nginx

停止所有容器

docker stop $(docker ps -a -q)

删除所有容器

docker rm $(docker ps -a -q)
