php(php-fpm)Docker基础镜像打包详解

1、启动纯静ubuntu容器

sudo docker run -it --name ubuntu-phpfpm7.3-0.1 registry.cn-beijing.aliyuncs.com/jd100-pub/ubuntu:20190304 /bin/bash

> 759668f30865

2、修改源

echo 'deb http://archive.ubuntu.com/ubuntu/ bionic main restricted

deb http://archive.ubuntu.com/ubuntu/ bionic-updates main restricted

deb http://archive.ubuntu.com/ubuntu/ bionic universe

deb-src http://archive.ubuntu.com/ubuntu/ bionic universe

deb http://archive.ubuntu.com/ubuntu/ bionic-updates universe

deb-src http://archive.ubuntu.com/ubuntu/ bionic-updates universe

deb http://archive.ubuntu.com/ubuntu/ bionic multiverse

deb http://archive.ubuntu.com/ubuntu/ bionic-updates multiverse

deb http://archive.ubuntu.com/ubuntu/ bionic-backports main restricted universe multiverse

deb http://security.ubuntu.com/ubuntu/ bionic-security main restricted

deb http://security.ubuntu.com/ubuntu/ bionic-security universe

deb-src http://security.ubuntu.com/ubuntu/ bionic-security universe

deb http://security.ubuntu.com/ubuntu/ bionic-security multiverse

' >/etc/apt/sources.list;

apt-get update

apt-get install software-properties-common

add-apt-repository ppa:ondrej/php

add-apt-repository ppa:ondrej/nginx

apt-get update

apt-get install -y php7.3-fpm （要求选择时区的时候选择 欧洲 （8Europe）/ 伦敦（27. London））

apt-get install -y nginx (nginx version: nginx/1.14.2)

(相关信息：php-pear

Creating config file /etc/php/7.3/fpm/php.ini with new version

）

========================

apt-get --purge remove php-common

apt-get install php-common php-mysql php-redis php-mbstring php-fpm php-gd php-tokenizer php-curl php-cli openssl

lume需要的扩展：

Mcrypt PHP Extension mcrypt (7.3版本使用openssl替代mcrypt ）

OpenSSL PHP Extension

查找安装php常用的扩展，容器：36cabe4eea3a

========================

查看php-fpm:

whereis php-fpm

/usr/sbin/php-fpm7.3 （启动fpm，启动时报ERROR: unable to bind listening socket for address '/run/php/php7.3-fpm.sock': No such file or directory, 此时先mkdir /run/php即可）

启动nginx

优化nginx配置

events {

use epoll;

worker_connections 51200;

multi_accept on;

}

gzip on;

gzip_disable "msie6";

gzip_vary on;

gzip_proxied any;

# gzip_comp_level 6;

gzip_min_length 1k;

gzip_buffers 16 8k;

gzip_http_version 1.1;

gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

优化php-fpm

cat /etc/php/7.3/fpm/php-fpm.conf

新建开机启动脚本（需要开机启动的加入到里面）

/opt/autorun/reboot.sh

（新建步骤：

1、在宿主机中新建/opt/autorun/reboot.sh

#!/bin/bash

/usr/sbin/php-fpm7.3

nginx

2、容器中新建目录

mkdir /opt/autorun/

3、sudo docker cp reboot.sh 91b004bc998c:/opt/autorun/reboot.sh

3d87c9b09b8d-镜像id

chmod 777 /opt/autorun/reboot.sh

将容器打基础镜像

1、sudo docker commit 759668f30865 ubuntu_nginx1.42_phpfpm7.3:0.2

2、使用Dockerfile测试试用（course-service目录下）

修改Dockerfile使用指定镜像

sudo docker build -t test-php7.3:1.0 .

3、启动测试

sudo docker run -d --name test-php-v1.0 -p 9003:80 test-php7.3:1.0

直接访问宿主机：http://172.16.0.215:9003/

(测试过程命令）

sudo docker cp index.php 3943df1e1fa7:/var/www/html

sudo docker cp default 3943df1e1fa7:/etc/nginx/sites-enabled/default

sudo docker cp php.ini 3943df1e1fa7:/etc/php/7.3/fpm/php.ini

nginx use www-data

php-fpm

chown -R www-data /var/www/html/

chgrp -R www-data /var/www/html/

sudo docker run -it --name test-php-v1.2 -p 9003:80 ubuntu_nginx1.42_phpfpm7.3:0.2

sudo docker build -t ubuntu-php7.3:0.14 .

通过添加reboot.sh做启动操作

FROM ubuntu-php7.3:0.13

CMD ["sh", "/opt/autorun/reboot.sh"]

遇到的问题：

配置apache2.4修改documentRoot出现You don't have permission to access / on this server

没有配置/etc/apache2/apache2.conf中的目录

docker启动后避免自动退出：

tail -f /dev/null

相关文件

reboot.sh

#!/bin/bash

/usr/sbin/php-fpm7.3

nginx

tail -f /dev/null

或者：

#!/bin/bash

/usr/sbin/php-fpm7.3

nginx -g "daemon off;"

apt-cache search php

注意大坑：fpm与nginx通讯使用9000端口形式，不要使用socket形式，出错率很高
