wordpress昇級php版本-使用docker phpFPM

1.上wordpress docker 找到要的版本

wordpress docker hub

2.把Dockerfile下方下載wordpress tar功能拿掉

COPY docker-entrypoint.sh /usr/local/bin/
 

ENTRYPOINT ["docker-entrypoint.sh"]
CMD ["php-fpm"]

3.倒數第三行加上執行權限

RUN chmod +x /usr/local/bin/docker-entrypoint.sh

4.最上方把www-data uid 跟gid都變成48

(host的apache user權限)(可用id -u apache)

FROM php:7.4-fpm

RUN usermod -u 48 www-data
RUN groupmod -g 48 www-data

5.把docker-entrypoint.sh只留執行php-fpm部份

#!/usr/bin/env bash
set -Eeuo pipefail

if [[ "$1" == apache2* ]] || [ "$1" = 'php-fpm' ]; then
        uid="$(id -u)"
        gid="$(id -g)"
        if [ "$uid" = '0' ]; then
                case "$1" in
                        apache2*)
                                user="${APACHE_RUN_USER:-www-data}"
                                group="${APACHE_RUN_GROUP:-www-data}"

                                # strip off any '#' symbol ('#1000' is valid sy$
                                pound='#'
                                user="${user#$pound}"
                                group="${group#$pound}"
                                ;;
                        *) # php-fpm
                                user='www-data'
                                group='www-data'
                                ;;
                esac
        else
                user="$uid"
                group="$gid"
        fi

fi

exec "$@"

COPY docker-entrypoint.sh /usr/local/bin/

RUN chmod +x /usr/local/bin/docker-entrypoint.sh

ENTRYPOINT ["docker-entrypoint.sh"]
CMD ["php-fpm"]

6.建立docker-compose.yml

version: "3.5"

services:

 #localhost:5050
  phpfpm:
    container_name: phpfpm7.4
    build: ./fpm
    environment:
      TZ: Asia/Taipei
    networks:
      phpfpm:
        ipv4_address: 162.17.239.2
    ports:
      - "127.0.0.1:9001:9000"

    restart: unless-stopped
    volumes:
      - /var/www:/var/www
    logging:
      options:
        max-size: 3G

networks:
  phpfpm:
   driver: bridge
   ipam:
      driver: default
      config:
        - subnet: 162.17.239.0/24

這裡設定一個docker network 讓php可以連的到host的mariadb database
這是一個test的php source

<?php
$server = "162.17.239.1";         # Host MySQL/MariaDB 伺服器 
$dbuser = "root";       # 使用者帳號 
$dbpassword = "byebye123"; # 使用者密碼 
$dbname = "wordpress";    # 資料庫名稱

# 連接 MySQL/MariaDB 資料庫
$connection = new mysqli($server, $dbuser, $dbpassword, $dbname);

# 檢查連線是否成功
if ($connection->connect_error) {
  die("連線失敗：" . $connection->connect_error);
}

# MySQL/MariaDB 指令
$sqlQuery = "select 1+1 as s from dual";

# 執行 MySQL/MariaDB 指令
if ($connection->query($sqlQuery) === TRUE) {
  echo "查詢成功";
} else {
  echo "執行失敗：" . $connection->error;
}

# 關閉 MySQL/MariaDB 連線
$connection->close();
?>

ps.可以使用netcat來檢查連線是否有通

sudo docker exec -ti phpfpm7.4 bash
apt update
apt install -y netcat
nc -zvw3 162.17.239.1 3306

ps.記得把mariadb的帳號開啟可以讓“`162.17.239.%“`連入

7.修改wordpress/wp-config.php

DB_HOST為162.17.239.1

8.修改virtualhost設定

ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9001/var/www/mywordpress/$1
