docker部署lnmp环境

Posted 2022-01-31 徐中祥

Dokcer部署php项目

一,LNMP环境搭建

1，网段规划：172.18.10.0/24

172.18.10.10	nginx容器
172.18.10.20	mysql容器
172.18.10.30	php容器
172.18.10.40	crawl容器

2，镜像版本选择

Nginx : nginx:latest
mysql : mysql:latest
PHP   : php:7.3-fpm
python: python:3.7

3，拉取镜像

docker pull nginx
docker pull mysql
docker pull php:7.3-fpm
docker pull python:3.7

4，设置网络

创建一个自定义桥接网络

docker network create  -d bridge  --subnet 172.18.10.0/24 --gateway 172.18.10.1 LNMP

5，nginx容器配置

# 运行一个测试容器
docker run  -itd --name  test-nginx nginx

# 拷贝配置文件
docker cp test-nginx:/etc/nginx /data/ngx_config
# 拷贝网站目录
docker cp test-nginx:/usr/share/nginx/html /data/ngx_www

# 删除测试容器
docker rm -f test-nginx

# 运行nginx容器
docker run -itd --name nginx-01 -v /data/ngx_config:/etc/nginx -v /data/ngx_www:/code -v /data/ngx_logs:/var/log/nginx -p 80:80 -p 8080:8080 --network LNMP  --ip 172.18.10.10 nginx:latest

6，MySQL容器配置

# 运行测试MySQL容器
docker run -itd --name test-mysql -e MYSQL_ROOT_PASSWORD=1QAZ2WSX_www mysql:latest

# 拷贝MySQL配置文件
docker cp test-mysql:/etc/mysql/conf.d /data/sql_config

# 删除测试容器
docker rm -f test-mysql

# 运行MySQL容器
docker run -it -d -p3306:3306 -v /data/sql_config:/etc/mysql/conf.d -v /data/sql_data:/var/lib/mysql -v /etc/localtime:/etc/localtime --name mysql-01 -e MYSQL_ROOT_PASSWORD=1QAZ2WSX_www --network LNMP --ip 172.18.10.20 mysql:latest

7，Dockerfile构建php镜像

[root@docker project]# cat dockerfile-php 
# 从官方基础版本构建
FROM php:7.3-fpm

RUN docker-php-ext-install -j$(nproc) gettext sockets pdo mysqli pcntl pdo_mysql iconv

RUN apt-get update  && apt-get install -y zlib1g-dev libicu-dev g++ telnet vim iputils-ping net-tools  libfreetype6-dev libjpeg62-turbo-dev  libpng-dev

# mysqli扩展
RUN cd /usr/local/bin/ \\
    && ./docker-php-ext-install gd mysqli \\
    && ./docker-php-ext-enable gd mysqli

# GD 扩展
#RUN rm -r /var/lib/apt/lists/* \\
#    && docker-php-ext-configure gd --with-jpeg=/usr/include/ --with-freetype=/usr/include/ \\
#    && docker-php-ext-install -j$(nproc) gd

# insl 扩展 
RUN docker-php-ext-configure intl && docker-php-ext-install intl

# imagick 扩展
#RUN export CFLAGS="$PHP_CFLAGS" CPPFLAGS="$PHP_CPPFLAGS" LDFLAGS="$PHP_LDFLAGS" \\
#    && apt-get install -y --no-install-recommends libmagickwand-dev \\
#    && rm -r /var/lib/apt/lists/* \\
#    && pecl install imagick-3.4.4 \\
#    && docker-php-ext-enable imagick

# mcrypt 扩展 
#RUN apt-get install -y --no-install-recommends libmcrypt-dev \\
#    && rm -r /var/lib/apt/lists/* \\
#    && pecl install mcrypt-1.0.2 \\
#    && docker-php-ext-enable mcrypt

# redis 扩展
RUN pecl install redis && docker-php-ext-enable redis

# xdebug 扩展
RUN pecl install xdebug && docker-php-ext-enable xdebug

# yaf 扩展
RUN pecl install yaf-3.1.4 && docker-php-ext-enable yaf

# swoole 扩展
#RUN pecl install swoole-4.4.0 && docker-php-ext-enable swoole

# opcache 扩展 
#RUN docker-php-ext-configure opcache --enable-opcache && docker-php-ext-install opcache


# 镜像信息
LABEL Author="xiaoxu"
LABEL Version="2021.6"
LABEL Description="PHP 7.4-fpm"


$(构建php镜像)
docker build -f dockerfile-php -t myphp .

• php容器配置

# 创建测试容器
docker run -itd --name test-php php:7.3-fpm
# 拷贝php配置文件
docker cp test-php:/usr/local/ /data/php_config/
# 删除测试容器
docker rm -f test-php

# 运行php容器
docker run -itd --name  php-01 -p 9000:9000 -v /data/ngx_www:/code -v /data/php_config:/usr/local/ -v /etc/localtime:/etc/localtime --network LNMP  --ip 172.18.10.30 php:v1

7，配置nginx连接php

# vim /data/ngx_config/conf.d/default.conf 
index  index.php index.html index.htm; #添加文件类型

    location ~ \\.php$ 
        root   /usr/share/nginx/html; #修改请求文件路径
        fastcgi_pass   172.18.10.30:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
        include        fastcgi_params;
    
    
# 测试nginx和php连接
echo "LNMP" > /data/ngx_www/index.html
cat > /data/ngx_www/test.php << EOF
<?php
    phpinfo();
?>
EOF

# 重启nginx容器
docker restart nginx-01 

9，搭建wordpress

# 下载并解压到代码发布目录
wget https://wordpress.org/latest.zip && unzip -d /data/ngx_www/ latest.zip

# 修改网站配置文件
vim /data/ngx_config/conf.d/default.conf 
    location / 
        root   /code/wordpress;
        index  index.html index.htm index.php;
    
    location ~ \\.php$ 
        fastcgi_pass   172.18.10.30:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /code/wordpress$fastcgi_script_name;
        include        fastcgi_params;
    


# 重启nginx
docker restart nginx-01

# 数据库授权用户
docker exec -it mysql-01 /bin/bash
mysql -uroot -p1QAZ2WSX_www
create database wordpress charset utf8mb4;
create user 'wp'@'%' identified by '1QAZ2WSX_www';
GRANT ALL PRIVILEGES ON wordpress.* TO 'wp'@'%' WITH GRANT OPTION;
ALTER USER 'wp'@'%' IDENTIFIED WITH mysql_native_password BY '1QAZ2WSX_www';
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '1QAZ2WSX_www';
flush privileges;



# 修改wordpress连接数据库代码
cd /data/ngx_www/wordpress/ && cp wp-config-sample.php wp-config.php && vim wp-config.php 

/** The name of the database for WordPress */
define( 'DB_NAME', 'wordpress' );
/** MySQL database username */
define( 'DB_USER', 'wp' );
/** MySQL database password */
define( 'DB_PASSWORD', '1QAZ2WSX_www' );
/** MySQL hostname */
define( 'DB_HOST', '172.18.10.20' );
/** Database Charset to use in creating database tables. */
define( 'DB_CHARSET', 'utf8mb4' );


# 修改文件
sed -i "s/mysql_connect/mysqli_connect/g" /data/ngx_www/wordpress/wp-includes/wp-db.php

10，测试php连接数据库

# vim /data/ngx_www/wordpress/test.php 
<?php
    $servername = "172.18.10.20";
    $username = "wp";
    $password = "1QAZ2WSX_www";
    // 创建连接
    $conn = mysqli_connect($servername, $username, $password);
    // 检测连接
    if (!$conn) 
         die("Connection failed: " . mysqli_connect_error());
    
    echo "php连接MySQ成功...";
?>
