实验
实验：用dockerfile搭建LNMP论坛
架构：
一台docker虚拟机
docker部署nginx 1.22 指定ip地址172.111.0.10
docker部署mysql 8.0.30 指定ip地址172.111.0.20
docker部署php 8.1.27 指定ip地址172.111.0.30
docker只能单节点部署，就是只能在一台机器上部署，跨机器容器无法通信，需要k8s。
docker做高可用只能在节点上增加同一服务的容器数量 。
实验步骤：
1.在opt目录下 mkdir nginx mysql php
nginx镜像
cd nginx/
把nginx和wordpress两个安装包拖入进去
vim Dockerfile
FROM centos:7
MAINTAINER this is nginx <lnmp>
RUN rm -rf /etc/yum.repos.d/*
ADD http://mirrors.aliyun.com/repo/Centos-7.repo /etc/yum.repos.d/Centos-7.repo
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make
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_stub_status_module && make -j 4 && make install
ENV PATH /usr/local/nginx/sbin/:$PATH
#设置环境变量做系统识别
COPY nginx.conf /usr/local/nginx/conf/
ADD wordpress-6.4.2-zh_CN.tar.gz /usr/local/nginx/html/
RUN chmod 777 -R /usr/local/nginx/html/
EXPOSE 80
VOLUME ["/usr/local/nginx/html/"]
CMD ["/usr/local/nginx/sbin/nginx","-g","daemon off;"]
还需要在nginx目录下新建一个nginx.conf的配置文件
vim nginx.conf
worker_processes 1;
events {worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';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;}
}
}docker build -t nginx:lnmp .
创建自定义网络
docker network create --subnet=172.111.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetwork
创建容器
docker run -itd --name nginx -p 80:80 -m 1g -v /opt/nhtml:/opt/nginx --net mynetwork --ip 172.111.0.10 nginx:lnmp
docker exec -it nginx bash
在容器里面
yum -y install net-tools
netstat -antp | grep 80
看nginx的端口是否起来
cd /usr/local/nginx/html
看一下wordpress文件是否存在
访问虚拟机本机ip192.168.233.22
mysql镜像
cd mysql/
把mysql的安装包拖进来
写一个my.cnf的配置文件
vim my.cnf
[client]
port = 3306
socket=/usr/local/mysql/mysql.sock[mysqld]
user = mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data

VOLUME ["/usr/local/mysql"]

docker build -t nginx:lnmp .
创建容器
docker run -itd --name mysql -p 3306:3306 --privileged -v /opt/mysql1:/opt/mysql --net mynetwork --ip 172.111.0.20 mysql:lnmp
docker exec -it mysql bash
进入数据库
mysql -u root -p
create database wordpress;
CREATE USER 'root'@'%' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
CREATE USER 'wordpress'@'%' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpress'@'%';
flush privileges;
php镜像
cd php/
把php的安装包拖入进来并且把三个配置文件也拖进来
vim Dockerfile

查看nginx和mysql文件是否在和php在local目录下
cd mysql/
查看mysql.sock文件是否存在
cd /usr/local/nginx/html
查看wordpress文件是否存在
yum -y install net-tools
netstat -antp | grep 9000
查看端口是否起来
