通过docker构建基于LNMP的WordPress项目

目录

1.准备nginx

2.准备mysql

3.准备php

4.构建各镜像

5.运行wordpress

---

1、项目环境：
1.1	（1）公司在实际的生产环境中，需要使用Docker 技术在一台主机上创建LNMP服务并运行Wordpress网站平台。然后对此服务进行相关的性能调优和管理工作。 （2）环境描述 主机 操作系统 IP地址 主要软件 Docker CentOS 7.3 x86_64 192.168.1.101 Docker 19.03
2、任务需求
2.1	（1）使用Docker构建LNMP环境并运行Wordpress网站平台。 （2）限制Nginx容器最多使用500Mb的内存和1G的Swap。 （3）限制Mysql容器写 /dev/sda 的速率为 10 MB/s。 （4）将所有容器进行快照，然后将Docker镜像打包成tar包备份到本地。

1.准备nginx

注：可以以上篇博客中nginx构建为基础

上传nginx.conf文件、上传阿里云镜像、上传html目录

2.准备mysql

cd /opt
mkdir mysql

COPY  my.cnf /etc/my.cnf
RUN useradd -M -s /sbin/nologin mysql &&\
    chown -R mysql:mysql /usr/local/mysql/ &&\
    chown mysql:mysql /etc/my.cnf &&\
    /usr/local/mysql/bin/mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
ENV PATH=$PATH:/usr/local/mysql/bin:/usr/local/mysql/lib
EXPOSE 3306
CMD ["/usr/local/mysql/bin/mysqld"]

vim my.cnf
[client]
port = 3306
socket=/usr/local/mysql/mysql.sock

[mysqld]
user = mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port = 3306
character-set-server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket=/usr/local/mysql/mysql.sock
bind-address = 0.0.0.0

上传阿里云镜像、mysql压缩包

3.准备php

vim Dockerfile
FROM centos:7 as first
ADD php-7.1.10.tar.bz2 /opt/
COPY CentOS-Base.repo /etc/yum.repos.d/
RUN yum -y install gd \
libjpeg libjpeg-devel \
libpng libpng-devel \
freetype freetype-devel \
libxml2 libxml2-devel \
zlib zlib-devel \
curl curl-devel \
openssl openssl-devel \
gcc gcc-c++ make pcre-devel && \
    yum clean all && \
    cd /opt/php-7.1.10/ && \
    ./configure \
--prefix=/usr/local/php \
--with-mysql-sock=/usr/local/mysql/mysql.sock \
--with-mysqli \
--with-zlib \
--with-curl \
--with-gd \
--with-jpeg-dir \
--with-png-dir \
--with-freetype-dir \
--with-openssl \
--enable-fpm \
--enable-mbstring \
--enable-xml \
--enable-session \
--enable-ftp \
--enable-pdo \
--enable-tokenizer \
--enable-zip && make -j 2 && make install
COPY php.ini /usr/local/php/lib/php.ini
COPY php-fpm.conf /usr/local/php/etc/php-fpm.conf
COPY www.conf /usr/local/php/etc/php-fpm.d/www.conf

FROM centos:7
COPY --from=first /usr/local/php/ /usr/local/php/
COPY CentOS-Base.repo /etc/yum.repos.d/
RUN useradd -M -s /sbin/nologin nginx &&\
yum -y install gd \
libjpeg-devel \
libpng-devel \
freetype-devel \
libxml2-devel \
zlib-devel \
curl-devel \
openssl-devel &&\
yum clean all
EXPOSE 9000
CMD ["/usr/local/php/sbin/php-fpm", "-F"]

上传php压缩包、阿里云镜像、php-fpm.conf  php.ini  www.conf

4.构建各镜像

cd /opt/nginx_bian    #构建nginx镜像
docker build -t nginx:lnmp .

cd /opt/php    #构建php镜像
docker build -t php:lnmp .

docker network create --subnet=172.18.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetwork   #自定义网络
docker network ls 

测试nginx、php

cd /opt/nginx_bian/

docker run --name nginx -d -p 80:80 -v /opt/nginx_bian/html:/usr/local/nginx/html/ --network mynetwork --ip 172.18.0.10 nginx:lnmp
docker ps -a

docker run --name php -d -p 9000:9000 --volumes-from nginx --network mynetwork --ip 172.18.0.30 php:lnnmp

docker ps -a

docker run --name php -d -p 9000:9000 --volumes-from nginx --network mynetwork --ip 172.18.0.30 php:lnnmp
docker ps -a

cd /opt/mysql
docker build -t mysql:lnmp .  #构建mysql镜像

docker run --name mysql -d --privileged -v /usr/local/mysql --network mynetwork --ip 172.18.0.20 mysql:lnmp   #启动容器
docker ps -a

mysql配置

docker exec -it mysql bash
mysqladmin -u root -p password "abc123"  #设置密码
mysql -u root -pabc123  #登录mysql
grant all on *.* to 'root'@'%' identified by 'abc123';
quit
exit
docker stop php
docker rm php

docker run --name php -d -p 9000:9000 --volumes-from nginx --volumes-from mysql --network mynetwork --ip 172.18.0.30 php:lnnmp

浏览器验证

5.运行wordpress

浏览器访问：http://192.168.9.113/wordpress/index.php

docker exec -it mysql bash
mysql -u root -pabc123
create database wordpress;
grant all on wordpress.* to 'wordpress'@'%' identified by 'admin123';
flush privileges;
quit
exit
cd /opt/nginx_bian/html
chmod 777 wordpress/
