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@001 ~]# cat /etc/centos-releaseCentOS Linux release 7.9. (Core)[root@001 ~]#
2.2 docker
[root@001 soft]# docker-compose -vDocker Compose version v2.16.0[root@001 soft]# docker -vDocker version 23.0.1, build a5ee5b1[root@001 soft]#
三 实施
相关镜像在docker hub 官网下载 /
3.1 安装docker 以及dockercompose
具体参看该文/nasooo/article/details/129753140
3.1 安装nginx
3.1.1 获取镜像
[root@001 soft]# docker pull nginx:stable-perl
[root@001 soft]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEnginx stable-perl b4c217053922 22 hours ago 190MB[root@001 soft]#
3.1.2 运行
[root@001 soft]# docker run -p 80:80 --name commonnginx -d nginx:stable-perl8a3487ef5818167e1475856cfd9707c55f713e8d146e08131671c78149c3fd07[root@001 soft]# docker ps -aCONTAINER ID IMAGECOMMAND CREATED STATUS PORTS NAMES8a3487ef5818 nginx:stable-perl "/docker-entrypoint.…" 3 seconds ago Up 2 seconds 0.0.0.0:80->80/tcp, :::80->80/tcp commonnginx[root@001 soft]#
3.1.3 验证
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@001 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@001 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@001 commonapp]# docker pull bitnami/php-fpm:7.4.327.4.32: Pulling from bitnami/php-fpm1d8866550bdd: Pull complete586e9578d6ca: Pull completeDigest: sha256:75b8ad4221f0215ad73947e342659a43d7d9bc382fd591a3ecfc3970706ff0a3Status: Downloaded newer image for bitnami/php-fpm:7.4.32docker.io/bitnami/php-fpm:7.4.32[root@001 commonapp]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEnginx stable-perl b4c217053922 25 hours ago 190MBbitnami/php-fpm 7.4.32 85b93689d207 5 months ago 329MB[root@001 commonapp]#
3.2.2 配置

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-fpmlocation ~ \.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@001 dockercomposescript]# docker-compose -f commonapp.yml up -d
[root@001 dockercomposescript]# docker ps -aCONTAINER ID IMAGECOMMAND CREATEDSTATUSPORTS NAMES6ea54c26796c nginx:stable-perl "/docker-entrypoint.…" 12 seconds ago Up 10 seconds 0.0.0.0:80->80/tcp, :::80->80/tcp commonappnginx935121a60fc6 bitnami/php-fpm:7.4.32 "php-fpm -F --pid /o…" 16 hours agoUp 16 hours9000/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>
3.4 安装mysql
3.4.1 获取镜像
3.4.2 配置
mysql:image: /mysql:5.7.33restart: alwayscontainer_name: commonappmysqlenvironment:MYSQL_ROOT_PASSWORD: xxxxx.123ports:- 3306:3306volumes:- /data/yunweipro/commonapp/mysql:/var/lib/mysql- /data/yunweipro/backup/commonapp/mysqlbackupdata:/data/backupcommand:--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@001 dockercomposescript]# mkdir -p /data/yunweipro/commonapp/mysql[root@001 dockercomposescript]# mkdir -p /data/yunweipro/backup/commonapp/mysqlbackupdata
3.4.3 运行

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';
