一 摘要

本文主要介绍基于docker docker-compose 安装 lnmp 三件套,以及用phpmysadmin 验证下部署可正确。

二 环境信息

2.1 操作系统

[root@2023001 ~]# cat /etc/centos-release
CentOS Linux release 7.9.2009 (Core)
[root@2023001 ~]#

2.2 docker

[root@2023001 soft]# docker-compose -v
Docker Compose version v2.16.0
[root@2023001 soft]# docker -v
Docker version 23.0.1, build a5ee5b1
[root@2023001 soft]#

三 实施

相关镜像在docker hub 官网下载 https://hub.docker.com/

3.1 安装docker 以及dockercompose

具体参看该文https://blog.csdn.net/nasooo/article/details/129753140

3.1 安装nginx

3.1.1 获取镜像

[root@2023001 soft]# docker pull nginx:stable-perl
[root@2023001 soft]# docker images
REPOSITORY   TAG           IMAGE ID       CREATED        SIZE
nginx        stable-perl   b4c217053922   22 hours ago   190MB
[root@2023001 soft]#

3.1.2 运行

[root@2023001 soft]# docker run -p 80:80 --name commonnginx -d nginx:stable-perl
8a3487ef5818167e1475856cfd9707c55f713e8d146e08131671c78149c3fd07
[root@2023001 soft]# docker ps -a
CONTAINER ID   IMAGE               COMMAND                  CREATED         STATUS         PORTS                               NAMES
8a3487ef5818   nginx:stable-perl   "/docker-entrypoint.…"   3 seconds ago   Up 2 seconds   0.0.0.0:80->80/tcp, :::80->80/tcp   commonnginx
[root@2023001 soft]#

3.1.3 验证

在这里插入图片描述

3.1.4 基于docker-compose 安装

3.1.4.1 docker-compose 脚本
version: '1.1'
services:
    nginx:
        image: nginx:stable-perl     # 镜像名称
        container_name: commonappnginx     # 容器名字
        restart: always     # 开机自动重启
        ports:     # 端口号绑定(宿主机:容器内)
            - '80:80'
            - '443:443'
        volumes:      # 目录映射(宿主机:容器内)
            - /data/yunweipro/commonapp/nginx/conf/nginx.conf:/etc/nginx/nginx.conf
            - /data/yunweipro/commonapp/nginx/conf.d:/etc/nginx/conf.d
            - /data/yunweipro/commonapp/nginx/html:/usr/share/nginx/html
            - /data/yunweipro/commonapp/nginx/logs:/var/log/nginx
3.1.4.2 目录结构
[root@2023001 commonapp]# tree -a
.
├── dockercomposescript
│   └── commonappnginx.yml
└── nginx
    ├── conf
    │   └── nginx.conf   
    ├── conf.d
    │   └── default.conf
    ├── html
    │   └── index.html
    └── logs
        ├── access.log
        └── error.log

启动之前,必须在该目录下 添加,一般先启动个同版本的容器 docker cp 出来

nginx.conf
default.conf
index.html
缺少这三个文件 ,nginx 会出现异常。
通过注释脚本每一行 定位错误

3.1.4.3 启动
[root@2023001 dockercomposescript]# docker-compose -f commonappnginx.yml up -d
3.1.4.4 验证目录映射

修改/data/yunweipro/commonapp/nginx/html/index.html

3.2 安装php-fpm

3.2.1 获取镜像

[root@2023001 commonapp]# docker pull bitnami/php-fpm:7.4.32
7.4.32: Pulling from bitnami/php-fpm
1d8866550bdd: Pull complete

Status: Downloaded newer image for bitnami/php-fpm:7.4.32

[root@2023001 commonapp]# docker images
REPOSITORY        TAG           IMAGE ID       CREATED        SIZE
nginx             stable-perl   b4c217053922   25 hours ago   190MB
bitnami/php-fpm   7.4.32        85b93689d207   5 months ago   329MB
[root@2023001 commonapp]#

3.2.2 配置

version: '2'
services:
    nginx:
        image: nginx:stable-perl     # 镜像名称
        container_name: commonappnginx     # 容器名字
        restart: always     # 开机自动重启
        ports:     # 端口号绑定(宿主机:容器内)
            - '80:80'
        volumes:      # 目录映射(宿主机:容器内)
            - /data/yunweipro/commonapp/nginx/conf/nginx.conf:/etc/nginx/nginx.conf
            - /data/yunweipro/commonapp/nginx/conf.d:/etc/nginx/conf.d
            - /data/yunweipro/commonapp/nginx/html:/usr/share/nginx/html
            - /data/yunweipro/commonapp/nginx/logs:/var/log/nginx
    php:
        image: bitnami/php-fpm:7.4.32     # 镜像名称
        container_name: php     # 容器名字
        restart: always     # 开机自动重启
#        ports:     # 端口号绑定(宿主机:容器内)
#            - '9000:9000'
        volumes:      # 目录映射(宿主机:容器内)
            - /data/yunweipro/commonapp/nginx/html:/usr/share/nginx/html

conf.d/default.conf 添加此段


    #当请求网站下php文件的时候,反向代理到php-fpm
    location ~ \.php$ {
        fastcgi_pass   php:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html/$fastcgi_script_name;
        include        fastcgi_params;
    }

3.2.3 运行

[root@2023001 dockercomposescript]# docker-compose -f commonapp.yml up -d
[root@2023001 dockercomposescript]# docker ps -a
CONTAINER ID   IMAGE                    COMMAND                  CREATED          STATUS          PORTS                               NAMES
6ea54c26796c   nginx:stable-perl        "/docker-entrypoint.…"   12 seconds ago   Up 10 seconds   0.0.0.0:80->80/tcp, :::80->80/tcp   commonappnginx
935121a60fc6   bitnami/php-fpm:7.4.32   "php-fpm -F --pid /o…"   16 hours ago     Up 16 hours     9000/tcp                            php

3.2.4 验证

在/data/yunweipro/commonapp/nginx/html 目录下 放个info.php 文件,文件内容如下

<html>
<head>
<title>PHP 测试</title>
</head>
<body><?php phpinfo(); ?></body>
</html>

在这里插入图片描述

3.4 安装mysql

3.4.1 获取镜像

3.4.2 配置

    mysql:
        image: registry.kxdigit.com/mysql:5.7.33
        restart: always
        container_name: commonappmysql
        environment:
        		MYSQL_ROOT_PASSWORD: xxxxx.123
        ports:
            - 3306:3306
        volumes:
            - /data/yunweipro/commonapp/mysql:/var/lib/mysql
            - /data/yunweipro/backup/commonapp/mysqlbackupdata:/data/backup
        command:
            --lower_case_table_names=1
            --transaction-isolation=READ-COMMITTED
            --max_allowed_packet=34M
            --innodb_log_file_size=256M
            --character-set-server=utf8
            --collation-server=utf8_bin
            --log-bin=mysql-bin
            --server-id=1

新建目录

[root@2023001 dockercomposescript]# mkdir -p /data/yunweipro/commonapp/mysql
[root@2023001 dockercomposescript]# mkdir -p /data/yunweipro/backup/commonapp/mysqlbackupdata

3.4.3 运行

[root@2023001 dockercomposescript]# docker-compose -f commonapp.yml up -d
[+] Running 3/3
 ⠿ Container commonappmysql  Started                                                                                                            0.9s

[root@2023001 dockercomposescript]#

3.5 安装phpmysadmin

我这里是下载phpmyadmin 文件然后放到 nginx 下运行,而不是直接安装phpmyadmin 容器

3.5.1 关键配置

config.inc.php 配置数据库地址

commonappmysql 即是上面mysql 的容器名。

$cfg['Servers'][$i]['host'] = 'commonappmysql';

3.5.2 验证
