【Docker实战】基于Dockerfile搭建LNMP+wordpress

一、项目背景和要求

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

二、架构：


nginx	172.111.0.10	docker-nginx
mysql	172.111.0.20	docker-mysql
PHP	172.111.0.30	docker-PHP

三、部署过程

#关闭防火墙和selinux
systemctl stop firewalld 
systemctl disable firewalld
setenforce 0

1、创建自定义网络：

docker network create --subnet=172.111.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetwork

2、部署nginx

基于Dockerfile创建nginx镜像：
容器ip：172.111.0.10

cd /opt
mkdir nginx mysql php
cd nginx

将nginx的安装包放到nginx目录中
在这里插入图片描述

vim nginx.conf
创建nginx.conf文件，后续要将nginx.conf文件COPY到容器中

worker_processes  1;
events {worker_connections  1024;
}
http {include       mime.types;default_type  application/octet-stream;sendfile        on;keepalive_timeout  65;server {listen       80;server_name  localhost;charset utf-8;location / {root   html;index  index.html index.php;}error_page   500 502 503 504  /50x.html;location = /50x.html {root   html;}location ~ \.php$ {root           html;fastcgi_pass   172.111.0.30:9000;fastcgi_index  index.php;fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;include        fastcgi_params;}
}
}

nginx Dockerfile：

FROM centos:7
RUN yum -y install gcc pcre-devel openssl-devel zlib-devel openssl openssl-devel
ADD nginx-1.22.0.tar.gz /usr/local/src/
RUN useradd -M -s /sbin/nologin nginx
WORKDIR /usr/local/src/nginx-1.22.0
RUN ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream --with-stream_ssl_module --with-stream_realip_module && make -j 4 && make install
ENV PATH /usr/local/nginx/sbin:$PATH
COPY nginx.conf /usr/local/nginx/conf/
ADD wordpress-6.4.2-zh_CN.tar.gz /usr/local/nginx/html
RUN chmod -R 777 /usr/local/nginx/html
EXPOSE 80
VOLUME ["/usr/local/nginx/html/"]
CMD ["/usr/local/nginx/sbin/nginx","-g","daemon off;"]

在这里插入图片描述

创建nginx容器：

docker build -t nginx:lnmp .

启动nginx容器：

docker run -itd --name nginx1 -p 80:80 -v /opt/nginx:/opt/nginxlogs --net mynetwork --ip 172.111.0.10 nginx:lnmp

检测：
20.0.0.51:80

3、部署mysql

基于Dockerfile创建mysql镜像：
在这里插入图片描述

cd /opt/mysql
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
skip-name-resolve
max_connections=2048
default-storage-engine=INNODB
max_allowed_packet=16M
server-id = 1
general_log=ON
general_log_file=/usr/local/mysql/data/mysql_general.logsql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES

在这里插入图片描述

mysql Dockerfile：

FROM centos:7
RUN yum -y install ncurses ncurses-devel bison cmake pcre-devel zlib-devel gcc gcc-c++ make && useradd -M -s /sbin/nologin mysql
ADD mysql-boost-5.7.20.tar.gz /usr/local/src
WORKDIR /usr/local/src/mysql-5.7.20/
RUN cmake \

mysql -u root -p

create database wordpress;
grant all privileges on wordpress.* to 'wordpress'@'%' identified by '123456';
grant all privileges on *.* to 'root'@'%' identified by '123456';
