docker搭建nginx+php环境的两种方式

# 搜索nginx镜像
docker search nginx
# 拉取nginx镜像
docker pull nginx
# 检查镜像是否拉取成功
docker images
# 运行一个测试的nginx
docker run -d --name nginxtest nginx
# 把容器里的nginx目录复制出来,配置是放在/etc/nginx
docker cp nginxtest:/etc/nginx ./
# 把容器里的log目录复制出来,日志是放在/var/log
docker cp nginxtest:/var/log ./
# 删除测试的nginx-test
docker rm -f nginxtest
# 查看nginx配置结构

# 拉取php镜像
docker pull php:7.4.28-fpm
# 检查镜像是否拉取成功
docker images
# 运行一个测试的nginx
docker run -d --name phptest php:7.4.28-fpm
# 把容器里的php目录复制出来,进容器php -i | grep php.ini可查看配置文件目录
docker cp phptest:/usr/local/etc/php ./
# 删除测试的php-test
docker rm -f phptest
# 查看php目录
[root@localhost ~]# tree php

方式一：

# 生成php容器
docker run -p 9000:9000 -d --name myphp \
-v /data/www:/usr/share/nginx/www \
-v /data/php/conf.d/php.ini:/usr/local/etc/php/php.ini \
php:7.4.28-fpm;

# 查询IPAddress
docker inspect myphp

[root@localhost www]# cat /data/nginx/conf.d/default.conf 
server {
    listen  80 default_server;
    server_name  localhost;

    root  /usr/share/nginx/www;
    location / {
        index index.html index.htm index.php;
    }

    location ~ \.php$ {
        fastcgi_pass   172.17.0.3:9000;  # docker inspect myphp查询的IPAddress改这里
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

# 生成nginx容器
docker run -p 80:80 -itd --name mynginx \
-v /data/www:/usr/share/nginx/www \
-v /data/nginx/conf.d/default.conf:/etc/nginx/conf.d/default.conf \
-v /data/nginx/log:/var/log/nginx \
nginx:latest;

方式二：
