dockerfile搭建部署LNMP

实验步骤：

nginx部分

mysql部分

php部分

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
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
sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

vim Dockerfile

FROM centos:7

--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
VOLUME ["/usr/local/mysql"]
ENTRYPOINT ["./mysqld"]

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

docker run -itd --name php --net mynetwork --ip 172.111.0.30 -p 9000:9000 --volumes-from nginx --volumes-from mysql php:lnmp

docker exec -it php bash

cd /usr/local/

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
