拓扑图

需求

编写Dockerfile，搭建lnmp架构

步骤

1、拉取相关Docker镜像

docker pull nginx:latest
docker pull mysql:5.7.32
docker pull php:7.4-fpm
docker pull tomcat:8

2、创建相关目录

mkdir -p /lnmp/{mysql,nginx,php}/{conf,data,log}

3、部署MySQL容器

1）创建MySQL变量文件

cat > /lnmp/mysql/conf/mysql-init.sql <<EOF   
CREATE DATABASE wordpress;
CREATE DATABASE wecenter;
CREATE DATABASE zrlog;

grant all on wordpress.* to woadm@'%' identified by 'Wjx123.com';
grant all on wecenter.* to weadm@'%' identified by 'Wjx123.com';
grant all on zrlog.* to zradm@'%' identified by 'Wjx123.com';

FLUSH PRIVILEGES;
EOF

2）编写Dockerfile

[root@docker mysql]# vim Dockerfile
FROM mysql:5.7.32
ENV MYSQL_ROOT_PASSWORD=Wjx123.com
ADD conf/mysql-init.sql /docker-entrypoint-initdb.d/

3）构建MySQL镜像

[root@docker mysql]# docker build -t mysql:wjx .

4）启动容器

docker run -d \
	--name mysql \
    --restart always \
	 mysql:wjx

4、部署php容器

1）创建apt源

cat > /lnmp/php/conf/sources.list <<EOF
deb http://mirrors.aliyun.com/debian/ bullseye main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ bullseye main non-free contrib
deb http://mirrors.aliyun.com/debian-security/ bullseye-security main
deb-src http://mirrors.aliyun.com/debian-security/ bullseye-security main
deb http://mirrors.aliyun.com/debian/ bullseye-updates main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ bullseye-updates main non-free contrib
deb http://mirrors.aliyun.com/debian/ bullseye-backports main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ bullseye-backports main non-free contrib
EOF

cat > /lnmp/php/conf/php.ini <<EOF
upload_max_filesize = 50M
post_max_size = 50M
EOF

2）编写Dockerfile

[root@docker php]# vim Dockerfile
FROM php:7.4-fpm
ADD conf/sources.list /etc/apt/
ADD conf/php.ini /usr/local/etc/php/conf.d/
RUN apt update && \
	apt install -y libwebp-dev libjpeg-dev libpng-dev libfreetype6-dev libzip-dev zlib1g-dev &&\
	docker-php-ext-configure gd --enable-gd --with-freetype --with-webp --with-jpeg  && \
	docker-php-ext-install gd mysqli pdo_mysql

3）构建php镜像

[root@docker php]# docker build -t php:wjx .

4）运行php容器

docker run -d \
	--restart always \
	--name php-fpm \
	--link mysql \
	-v /lnmp/nginx/data/:/web/www/ \
	php:wjx

5）修改php文件权限

chown -R 33.33 /lnmp/nginx/data/wecenter
chown -R 33.33 /lnmp/nginx/data/wordpress

5、部署nginx容器

# 编写nginx配置文件
vim /lnmp/nginx/conf/wordpress.conf
server {
	 server_name wordpress.wjx.com;
     listen 80;
 	 client_max_body_size 50M;
 	 root /web/www/wordpress;
 	 index index.php index.html;
 	 
 location ~ \.php$ {
 	fastcgi_pass  php-fpm:9000;
	 fastcgi_index index.php;
 	fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;
	 include    fastcgi_params;
 }
}

vim /lnmp/nginx/conf/wecenter.conf
server {
	server_name wecenter.wjx.com;
	 listen 80;
 	client_max_body_size 50M;
 	root /web/www/wecenter;
 	index index.php index.html;
 location ~ \.php$ {
 	fastcgi_pass  php-fpm:9000;
 	fastcgi_index index.php;
 	fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;
	 include    fastcgi_params;
 	}
}

#加压网页文件到指定目录
tar xf wordpress-zh_CN.tar.gz -C /lnmp/nginx/data/
unzip WeCenter_3-2-2.zip
mv WeCenter_3-2-2.zip /lnmp/nginx/data/wecenter

# 运行web01的nginx容器
docker run -d \
	--restart always \
	--name web01 \
	--link php-fpm \
	-v /lnmp/nginx/conf:/etc/nginx/conf.d \
	-v /lnmp/nginx/data/:/web/www/ \
	-v /lnmp/nginx/log/web01:/var/log/nginx \
	-p 80:80 \
	nginx:latest

6、部署Tomcat的容器

#上传zrlog到指定目录
ls /lnmp/nginx/data/zrlog
ROOT.war
#编写配置文件
cat /lnmp/nginx/conf/server.xml
......
<Host name="zrlog.wjx.com"  appBase="/web/zrlog"
      unpackWARs="true" autoDeploy="true">
   <Valve className="org.apache.catalina.valves.AccessLogValve"
directory="logs"
       prefix="zrlog_access_log" suffix=".txt"
              pattern="%h %l %u %t &quot;%r&quot; %s %b" />
  </Host>
</Engine>
</Service>
</Server>
#启动tom01容器
docker run -d \
	--restart always \
	--name tom01 \
	--link mysql \
	-v /lnmp/nginx/conf/server.xml:/usr/local/tomcat/conf/server.xml \
	-v /lnmp/nginx/data/zrlog:/web/zrlog \
	-p 8080:8080 \
	tomcat:8

7、访问网页
