docker 安装 lnmp环境

linux安装docker 参考

环境软件介绍

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

docker搭建的lnmp目录结构：

docker
│ └── nginx
│ │ └── default.conf #nginx配置文件
│ └── www
│ └── lmrs-2008 #lmrs的laravel项目代码

docker搭建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

我这边遇到一个问题
Error response from daemon: Get https://index.docker.io/v1/search?q=php&n=25: x509: certificate has expired or is not yet valid
解决：
yum install -y ntpdate
ntpdate ntp3.aliyun.com

[root@localhost ~]# docker pull nginx

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。

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

创建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镜像开启nginx应用容器

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：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 nginx：将容器命名为nginx
-v 将主机中当前目录下的www挂载到容器的www目录

#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

查看映射路径：docker inspect 容器id或name | grep Mounts -A 20

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7.4-fpm，其他版本的可自行选择

[root@localhost ~]# docker pull 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7.4-fpm的镜像。

[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镜像开启php-frm应用容器

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 :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 php：将容器命名为php
-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

[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

[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服务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;需要与我们查看的php容器的ip一致。

完成以上配置并且确定容器启动没有问题，可以进行测试： 进入浏览器 输入ip访问
访问laravel可能出现目录权限问题，以下是解决方式：

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

docker 搭建mysql

和nginx一样，我们可以先通过docker search mysql查找镜像，这里直接拉取官方的镜像

[root@localhost docker]# docker pull mysql

---

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

[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mysql 镜像开启mysql 应用容器

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 :将容器的3306端口映射到主机的3306端口
-d 后台运行(守护进程)
--name mysql：将容器命名为mysql
-v 将主机中的mysql配置挂载到容器的/etc/mysql/my.cnf

---

进入容器，连接mysql配置一个自己的用户，用于项目使用。

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

#连接mysql，密码就是我们在构建容器时镜像设置的MYSQL_ROOT_PASSWORD参数值
root@0ead771c95b4:/# mysql -uroot -p
Enter password:
