環境軟體介紹

1. docker
2. nginx
3. mysql
4. php7.4
5. laravel7

docker搭建的lnmp目錄結構：

docker
│ └── nginx
│ │ └── default.conf #nginx組態檔
│ └── www
│ └── lmrs-2008 #lmrs的laravel專案代碼

docker搭建nginx

我們可以使用docker search nginx命令查找 Docker Hub 上的 nginx 鏡像,這里直接拉取官方的鏡像

我這邊遇到一個問題
Error response from daemon: Get https://index.docker.io/v1/search?q=php&n=25: x509: certificate has expired or is not yet valid
解決：
yum install -y ntpdate
ntpdate ntp3.aliyun.com

[root@localhost ~]# docker pull nginx

等待下載完成后，我們就可以在本地鏡像串列里查到 REPOSITORY 為 nginx 的鏡像，

[root@localhost www]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
docker.io/nginx     latest              62d49f9bab67        12 days ago         133 MB

創建nginx配置

[root@localhost ~]# mkdir docker
[root@localhost ~]# mkdir docker/nginx
[root@localhost ~]# cd /docker/nginx
[root@localhost ~]# touch default.conf
[root@localhost ~]# vim default.conf

server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;
    root /docker/www/lmrs-2008/public;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /docker/www/lmrs-2008/public;
    }

    location ~ \.php$ {
        root /docker/www/lmrs-2008/public;
        fastcgi_pass   172.17.0.3:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

使用nginx鏡像開啟nginx應用容器

docker run -p 80:80 -d --name nginx -v /docker/nginx/default.conf:/etc/nginx/conf.d/default.conf -v /docker/www:/docker/www --privileged=true nginx

[root@localhost ~]# docker run -p 80:80 -d --name nginx -v /docker/nginx/default.conf:/etc/nginx/conf.d/default.conf -v /docker/www:/docker/www  --privileged=true nginx

-p 80:80：將容器的80埠映射到主機的80埠
-d 后臺運行(守護行程)
--name nginx：將容器命名為nginx
-v 將主機中當前目錄下的www掛載到容器的www目錄

#查看docker目前的容器
[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
8781afd1bf13        nginx               "/docker-entrypoin..."   About an hour ago   Up 17 minutes       0.0.0.0:80->80/tcp                  nginx

docker安裝php

和nginx一樣，我們可以先通過docker search php查找鏡像，這里直接拉取官方的鏡像,標簽為7.4-fpm，其他版本的可自行選擇

[root@localhost ~]# docker pull php:7.4-fpm

等待下載完成后，我們就可以在本地鏡像串列里查到REPOSITORY為php,標簽為7.4-fpm的鏡像，

[root@localhost docker]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
docker.io/nginx     latest              62d49f9bab67        12 days ago         133 MB
docker.io/php       7.4-fpm             41b17b0f90e6        2 weeks ago         405 MB

使用php鏡像開啟php-frm應用容器

docker run -p 9000:9000 -d --name php -v /docker/www:/docker/www --privileged=true php:7.4-fpm

[root@localhost docker]# docker run -p 9000:9000 -d --name php -v /docker/www:/docker/www --privileged=true php:7.4-fpm
-p 9000:9000 :將容器的9000埠映射到主機的9000埠
-d 后臺運行(守護行程)
--name php：將容器命名為php
-v 將主機中當前目錄下的www掛載到容器的www目錄

查看容器啟動情況

[root@localhost docker]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
cbf73ca0f17c        php:7.4-fpm         "docker-php-entryp..."   About an hour ago   Up About an hour    0.0.0.0:9000->9000/tcp              php
8781afd1bf13        nginx               "/docker-entrypoin..."   About an hour ago   Up 23 minutes       0.0.0.0:80->80/tcp                  nginx

到這里，可以看到nginx和php都運行成功(STATUS為up說明正在運行)

查看ip資訊

[root@localhost docker]# docker inspect php | grep "IPAddress"
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.3",
                    "IPAddress": "172.17.0.3",

查看nginx配置的php-fpm服務ip是否一致：

location ~ \.php$ {
    root /docker/www/lmrs-2008/public;
    fastcgi_pass   172.17.0.3:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}

以上配置中fastcgi_pass 172.17.0.3:9000;需要與我們查看的php容器的ip一致，

完成以上配置并且確定容器啟動沒有問題，可以進行測驗： 進入瀏覽器 輸入ip訪問
訪問laravel可能出現目錄權限問題，以下是解決方式：

[root@localhost docker]# cd /docker/www
[root@localhost www]# chmod -R 777 lmrs-2008

docker 搭建mysql

和nginx一樣，我們可以先通過docker search mysql查找鏡像，這里直接拉取官方的鏡像

[root@localhost docker]# docker pull mysql

等待下載完成后，我們就可以在本地鏡像串列里查到REPOSITORY為mysql的鏡像

[root@localhost docker]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
docker.io/mysql     latest              0627ec6901db        6 days ago          556 MB
docker.io/nginx     latest              62d49f9bab67        12 days ago         133 MB
docker.io/php       7.4-fpm             41b17b0f90e6        2 weeks ago         405 MB

使用php鏡像開啟php-frm應用容器

docker run -p 3306:3306 -d --name mysql -v /etc/my.cnf:/etc/mysql/my.cnf --privileged=true -e MYSQL_ROOT_PASSWORD=root mysql

[root@localhost docker]# docker run -p 3306:3306 -d --name mysql -v /etc/my.cnf:/etc/mysql/my.cnf --privileged=true -e MYSQL_ROOT_PASSWORD=root mysql

-p 3306:3306 :將容器的3306埠映射到主機的3306埠
-d 后臺運行(守護行程)
--name mysql：將容器命名為mysql
-v 將主機中的mysql配置掛載到容器的/etc/mysql/my.cnf

進入容器，連接mysql配置一個自己的用戶，用于專案使用，

[root@localhost docker]# docker exec -it mysql bash
root@0ead771c95b4:/#

#連接mysql，密碼就是我們在構建容器時鏡像設定的MYSQL_ROOT_PASSWORD引數值
root@0ead771c95b4:/# mysql -uroot -p
