实践说明:基于RHEL7(CentOS7.9)部署docker环境(23.0.1、24.0.2),所构建的php7.4.33镜像应用于RHEL7-9(如AlmaLinux9.1),但因为docker的特性,适用场景是不限于此的。
文档形成时期:2017-2023年
因系统或软件版本不同,构建部署可能略有差异,但本文未做细分,对稍有经验者应不存在明显障碍。
因软件世界之复杂和个人能力之限,难免疏漏和错误,欢迎指正。
PHP7.4模组选择说明
php-7.4.33发布时间是2022.11.03,各模组安装可以参考这个时间。
官方php:7.4.33-fpm镜像的临时容器
通过临时容器获得默认配置和模组信息(可选):
创建临时容器的目的主要是获得默认配置、模组等信息。
docker run -itd --name phpfpm-7.4.33-tmp php:7.4.33-fpm
进入容器查看默认配置
docker exec -it phpfpm-7.4.33-tmp /bin/bash
准备国内源,建议用http而不是https
/etc/apt/sources.list阿里云源准备,放构建当前目录
deb https://mirrors.aliyun.com/debian/ bullseye main non-free contrib
deb-src https://mirrors.aliyun.com/debian/ bullseye main non-free contrib

创建自定义网络
创建自定义网络,并指定网段、网关,只有定义了网段,才可以使用此网络为容器分配固定IP
docker network create -d bridge --subnet 10.1.5.0/24 --gateway 10.1.5.1 custom_bridge_net
php7.4.33_Dockerfile
基于官方php:7.4.33-fpm镜像默认模组、wordpress对php环境的要求,第三方php7.4.33部署常见模组,以及曾经的生产环境常用模组,最终整理了比较完整模组安装的Dockerfile文件。

php模组部署说明
参考:php模组部署说明
构建镜像
cd /root/sh/Dockerfiles/Independent
docker buildx build -t tmtcha/php:7.4.33-fpm-v1.02 -f /root/sh/Dockerfiles/Independent/php7.4.33_Dockerfile .
注:偶尔因网络问题构建失败,可调整模组构建顺序后重试。
构建时间:1049.9s,约17分钟
运行容器
容器运行失败,可查看日志
docker logs 容器ID或名称
以构建的镜像运行一个临时的容器,为查看和拷贝配置等文件。
删除之前的临时容器(如果有):docker stop phpfpm-7.4.33-tmp; docker rm phpfpm-7.4.33-tmp
docker run -itd --name phpfpm-7.4.33-tmp tmtcha/php:7.4.33-fpm-v1.02
可以看到,默认加载配置是这样的:
[root@localhost ~]# docker exec phpfpm-7.4.33-tmp /bin/bash -c "php --ini"
Configuration File (php.ini) Path: /usr/local/etc/php
Loaded Configuration File: (none)

/usr/local/etc/php/conf.d/docker-php-ext-zip.ini,
/usr/local/etc/php/conf.d/xx-php-ext-memcached.ini
配置均在/usr/local/etc/中,默认没有php.ini主配置,但仍然加载了构建过程中启用模组的子配置,
停止临时docker容器
docker stop phpfpm-7.4.33-tmp
拷贝配置到宿主机持久化目录中:
宿主机中执行:
mkdir -p /opt/docker_lnmp/{php74_cfg,php74_log}
docker cp phpfpm-7.4.33-tmp:/usr/local/etc /opt/docker_lnmp/php74_cfg
docker cp -a phpfpm-7.4.33-tmp:/usr/local/php74/var/log /opt/docker_lnmp/php74_log
注:会拷贝到目标路径下的子目录,需要再手动拷贝出来,并纠正权限,比如log文件应该是php-fpm运行用户所有,有可读写权限,因为用的www账户,容器内和宿主机的uid/gid一样,所以在宿主机执行chown www:www -R /opt/docker_lnmp/php74_log 也可以。
php配置
cd /opt/docker_lnmp/php74_cfg
cp -a php/php.ini-production php/php.ini
vi php/php.ini
php日志路径变更为 error_log = /usr/local/php74/var/log/php_errors.log
修改内存限制,上传文件大小等必要配置,
upload_max_filesize = 32M
post_max_size = 32M
php-fpm配置
注,下面一些配置在php-fpm.conf中,一些在子配置www.conf,zz-docker.conf,docker.conf
user = www-data
group = www-data
改为
user = www
group = www
侦听端口变更为9002
listen = 127.0.0.1:9002
zz-docker.conf中有侦听配置,实践中发现优先于www.conf的配置生效。
listen = 9002
php-fpm日志路径变更为 error_log = /usr/local/php74/var/log/php-fpm.log
实践中发现docker.conf有日志路径输出配置:
error_log = /proc/self/fd/2
access.log = /proc/self/fd/2
这优先于php-fpm.conf中的配置生效,docker.conf中默认配置应该是为了便于通过docker观察日志输出,进入容器查看日志或手动挂载日志和docker的使用设计原则不符吧,应该尽可能通过docker去管理和查看服务。不过前面dockerfile和后面容器创建中关于日志自定义配置可以权当一个备用方案。
child processes视业务场景修改
内存限制
php_admin_value[memory_limit] = 128M
停止临时docker容器,或可删除
docker stop phpfpm-7.4.33-tmp; # docker rm phpfpm-7.4.33-tmp
正式生产的容器和镜像
启动容器
docker run -dit --privileged=true
-p 9002:9002
–network custom_bridge_net --ip 10.1.5.131
-v /opt/web:/opt/web
-v /opt/docker_lnmp/php74_cfg:/usr/local/etc
-v /opt/docker_lnmp/php74_log:/usr/local/php74/var/log
–name=phpfpm-7.4.33-v1.02 tmtcha/php:7.4.33-fpm-v1.02
创建容器后重启容器:docker restart phpfpm-7.4.33-v1.02
测验
容器内查看和调试
安装必要软件包
apt update
apt install net-tools vim procps inetutils-ping telnet
该环境搭配宿主机的nginx+mysql,成功访问。
最终模组结果
[root@localhost php74_cfg]# docker exec -it phpfpm-7.4.33-v1.02 /bin/bash -c "php -m"
