使用docker搭建nginx+php7.4环境

docker 安装nginx

我们可以使用docker search nginx命令查找 Docker Hub 上的 nginx 镜像,这里直接拉取官方的镜像

[yaoyuan@VM-20-5-centos ~]# docker pull nginx
Using default tag: latest
latest: Pulling from library/nginx
5eb5b503b376: Pull complete 
1ae07ab881bd: Pull complete

Status: Downloaded newer image for nginx:latest
docker.io/library/nginx:latest

等待下载完成后，我们就可以在本地镜像列表里查到 REPOSITORY 为 nginx 的镜像。

[yaoyuan@VM-20-5-centos ~]$ docker images
REPOSITORY                    TAG       IMAGE ID       CREATED        SIZE

wangbinxingkong/fast          latest    878667fbb389   6 months ago   51.4MB

使用nginx镜像开启nginx应用容器

[yaoyuan@VM-20-5-centos docker_data]$ pwd
/data/docker_data
[yaoyuan@VM-20-5-centos docker_data]$ docker run -p 80:80 -d --name nginx_wwwz88jcom  -v /data/docker_data/nginx/www:/usr/share/nginx/www nginx
3968ad4b0bd400209d97ac69ae19be9e8598f94f54ef1c5577849b18729e3397

-p 80:80：将容器的80端口映射到主机的80端口
-d 后台运行(守护进程)
--name mynginx：将容器命名为mynginx
-v 将主机中当前目录下的www挂载到容器的www目录

查看容器启动情况

[lighthouse@VM-20-5-centos www]$ docker ps -a
CONTAINER ID   IMAGE                         COMMAND                  CREATED         STATUS         PORTS                                                                      NAMES

通过浏览器访问,运行成功

Docker 安装 PHP

和nginx一样，我们可以先通过docker search php查找镜像，这里直接拉取官方的镜像,标签为7.1-fpm，其他版本的可自行选择

[yaoyuan@VM-20-5-centos www]$ docker pull php:7.4-fpm

docker.io/library/php:7.4-fpm

等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为php,标签为7.1-fpm的镜像。

[yaoyuan@VM-20-5-centos www]$ docker images

使用php镜像开启php-frm应用容器

[yaoyuan@VM-20-5-centos www]$ docker run -p 9000:9000 -d --name php-fpm_wwwz88jcom -v /data/docker_data/nginx/www:/usr/share/nginx/www php:7.4-fpm
268d0ec3a9975f140adf67531d6c4f0cb3400747a16239e0d47c8b730c4421ef
[yaoyuan@VM-20-5-centos www]$

-p 9000:9000 :将容器的9000端口映射到主机的9000端口
-d 后台运行(守护进程)
--name myphp-fpm：将容器命名为myphp-fpm
-v 将主机中当前目录下的www挂载到容器的www目录

查看容器启动情况

[yaoyuan@VM-20-5-centos www]$ docker ps -a
CONTAINER ID   IMAGE                         COMMAND                  CREATED          STATUS          PORTS                                                                      NAMES
268d0ec3a997   php:7.4-fpm                   "docker-php-entrypoi…"   2 minutes ago    Up 2 minutes    0.0.0.0:9000->9000/tcp                                                     php-fpm_wwwz88jcom
3968ad4b0bd4   nginx                         "/docker-entrypoint.…"   15 minutes ago   Up 15 minutes   0.0.0.0:80->80/tcp                                                         nginx_wwwz88jcom

到这里，可以看到nginx和php都运行成功(STATUS为up说明正在运行)

查看ip信息

[yaoyuan@VM-20-5-centos www]$ docker inspect php-fpm_wwwz88jcom | grep "IPAddress"
        "SecondaryIPAddresses": null,
        "IPAddress": "172.17.0.6",
                "IPAddress": "172.17.0.6",

修改nginx相关配置

容器里面是没有vim，不能直接修改配置文件。当然我们也可以在容器里面安装vim，这里介绍另一种方法

进入正在运行的nginx容器

[yaoyuan@VM-20-5-centos www]$ docker exec -it nginx_wwwz88jcom bash
root@3968ad4b0bd4:/#

配置文件地址 /etc/nginx/conf.d/default.conf

root@3968ad4b0bd4:/# cd /etc/nginx/conf.d/
root@3968ad4b0bd4:/etc/nginx/conf.d# ls
default.conf
root@3968ad4b0bd4:/etc/nginx/conf.d#

然后使用ctrl + p + q退出容器，使用exit的话会让容器停止。
使用专用的复制命令将配置文件复制到宿主机，然后在宿主机进行编辑

[yaoyuan@VM-20-5-centos conf.d]$ sudo docker cp nginx_wwwz88jcom:/etc/nginx/conf.d/default.conf /data/docker_data/nginx/conf.d/default.conf
[yaoyuan@VM-20-5-centos conf.d]$

在宿主机修改配置文件的php部分，内容如下：

location ~ \.php$ {
fastcgi_pass   172.17.0.6:9000; 
fastcgi_index  index.php;
fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/www$fastcgi_script_name;
fastcgi_param  SCRIPT_NAME      $fastcgi_script_name;
include        fastcgi_params;
}

其中的ip也可以修改为宿主机的ip或者上面docker命令查看的ip。

然后使用复制命令将宿主机的文件复制到容器

[yaoyuan@VM-20-5-centos conf.d]$ docker cp /data/docker_data/nginx/conf.d/default.conf nginx_wwwz88jcom:/etc/nginx/conf.d/default.conf

进入容器中，重新载入nginx配置文件

[yaoyuan@VM-20-5-centos conf.d]$ docker exec -it nginx_wwwz88jcom bash
root@3968ad4b0bd4:/# service nginx reload
Reloading nginx: nginx.

大功告成

使用docker搭建nginx+php7.4环境

如果php后续需要安装扩展。

https://hub.docker.com/_/php?tab=description 可以去docker php介绍里面看看。里面有开启扩展的方法

pecl install redis-5.1.1 #安装扩展
docker-php-ext-enable redis #开启扩展
