Dockerfile建立LNMP平臺並上線php項目

實驗環境

系統版本：CentOS Linux release 7.6.1810 (Core)x64

Docker版本：18.09.5

關閉防火牆並禁止開機自啓

systemctl stop firewalld.service
systemctl disable firewalld

關閉selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux

重啓 reboot

安裝docker

一、安裝docker-ce的yum源

//下載yum源到本地

wget http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

//移動yum源到/etc/yum.repos.d/目錄下

mv docker-ce.repo /etc/yum.repos.d/

二、從高到低排列顯示docker版本

yum list docker-ce --showduplicates | sort -r

三、安裝docker最新版

yum -y install docker-ce .x86_64

注：切記啓動docker並設置開機自啓！

準備須要的鏡像

構建Dockerfile-Mysql鏡像

注：由於本身構建的數據庫不夠簡潔因此建議使用官方鏡像！

docker run -d --name lnmp_mysql --net lnmp --mount src=mysql-vol,dst=/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=wordpress mysql:5.7 --character-set-server=utf8

注：由於使用的官網鏡像簡潔包小而且不容易出問題，因此直接下載運行了！

構建Dockerfile-php鏡像

一、提早建立好php配置文件

php-fpm.conf php.ini

注：以上兩個文件與dockerfile-php文件在同一目錄，裏邊配置信息根據需求改正便可！

二、建立Dockerfile-php文件

cat Dockerfile-php

FROM centos:7
MAINTAINER www.ctnrs.com
RUN yum install epel-release -y && \
yum install -y gcc gcc-c++ make gd-devel libxml2-devel \
libcurl-devel libjpeg-devel libpng-devel openssl-devel \
libmcrypt-devel libxslt-devel libtidy-devel autoconf \
iproute net-tools telnet wget curl && \
yum clean all && \
rm -rf /var/cache/yum/*

RUN wget http://docs.php.net/distributions/php-5.6.36.tar.gz && \
tar zxf php-5.6.36.tar.gz && \
cd php-5.6.36 && \
./configure --prefix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \
--enable-fpm --enable-opcache \
--with-mysql --with-mysqli --with-pdo-mysql \
--with-openssl --with-zlib --with-curl --with-gd \
--with-jpeg-dir --with-png-dir --with-freetype-dir \
--enable-mbstring --with-mcrypt --enable-hash && \
make -j 4 && make install && \
cp php.ini-production /usr/local/php/etc/php.ini && \
cp sapi/fpm/php-fpm.conf /usr/local/php/etc/php-fpm.conf && \
sed -i "90a \daemonize = no" /usr/local/php/etc/php-fpm.conf && \
mkdir /usr/local/php/log && \
cd / && rm -rf php* && \
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

ENV PATH $PATH:/usr/local/php/sbin
COPY php.ini /usr/local/php/etc/
COPY php-fpm.conf /usr/local/php/etc/
WORKDIR /usr/local/php
EXPOSE 9000
CMD ["php-fpm"]

三、生成php鏡像

docker build -t hph:v1 -f Dockerfile-php .



注：dockerfile構建的鏡像在運行時須要添加一些參數，例如：內存、cpu、掛載目錄、自定義網絡卷等等。

構建Dockerfile-Nginx鏡像

一、建立dockerfile-nginx配置文件

nginx.conf

注：以上兩個文件與dockerfile-nginx文件在同一目錄，裏邊配置信息根據需求改正便可！

二、建立Dockerfile-Nginx文件

cat Dockerfile-nginx

FROM centos:7
MAINTAINER www.ctnrs.com
RUN yum install -y gcc gcc-c++ make \
openssl-devel pcre-devel gd-devel \
iproute net-tools telnet wget curl && \
yum clean all && \
rm -rf /var/cache/yum/
RUN wget http://nginx.org/download/nginx-1.15.5.tar.gz && \
tar zxf nginx-1.15.5.tar.gz && \
cd nginx-1.15.5 && \
./configure --prefix=/usr/local/nginx \
--with-http_ssl_module \
--with-http_stub_status_module && \
make -j 4 && make install && \
rm -rf /usr/local/nginx/html/ && \
echo "ok" >> /usr/local/nginx/html/status.html && \
cd / && rm -rf nginx-1.12.2* && \
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
ENV PATH $PATH:/usr/local/nginx/sbin
COPY nginx.conf /usr/local/nginx/conf/nginx.conf
WORKDIR /usr/local/nginx
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

三、生成nginx鏡像

docker build -t nginx:v1 -f Dockerfile-nginx .



注：dockerfile構建的鏡像在運行時須要添加一些參數，例如：內存、cpu、掛載目錄、自定義網絡卷等等。

建立docker網絡

一、建立lnmp自定義網絡

docker network create lnmp

注：建立自定義網絡是爲了實現項目之間的隔離！

二、建立mysql容器

docker run -d --name lnmp_mysql --net lnmp --mount src=mysql-vol,dst=/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=wordpress mysql:5.7 --character-set-server=utf8

注：將已有鏡像mysql:5.7指定以上參數便可！

三、建立PHP容器

docker run -d --name lnmp_php --net lnmp --mount src=wwwroot,dst=/wwwroot php:v1

注：根據已有鏡像php:v1指定以上參數運行！

四、建立Nginx容器

docker run -d --name lnmp_nginx --net lnmp -p 88:80 --mount src=wwwroot,dst=/wwwroot nginx:v1

注：根據已有鏡像nginx:v1指定以上參數運行！

五、以wordpress博客爲例

wordpress官網地址：https://wordpress.org

下載最新版本：https://wordpress.org/latest.zip

LNMP平臺上線wordpress項目

一、切換到存放php源碼的目錄

cd /var/lib/docker/volumes/wwwroot/_data/

注：默認狀況下目錄爲空，因此須要將下載好的wordpress源碼放進去！

二、上傳wordpress源碼包到指定目錄

wordpress-5.2.1.zip

三、解壓源碼包

unzip wordpress-5.2.1.zip

四、將目錄裏的文件放到當前_data目錄

mv wordpress/* ./

注：與壓縮包和解壓包在同一目錄！
