自定义Dockerfile 搭建LNMP架构

自定义Dockerfile搭建LNMP架构

1. 创建挂载目录,将wordpress解压到挂载目录

wget https://cn.wordpress.org/latest-zh_CN.tar.gz 
mkdir /tmp/html
tar -xf latest-zh_CN.tar.gz -C /tmp/
cd /tmp/html 
mv /tmp/wordpress/* .

2. 创建网桥

docker network create lnmp

3. 构建PHP镜像

# 创建PHP镜像的Dockerfile
FROM centos:7
RUN rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
RUN rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
RUN yum -y install php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-fpm php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml
RUN useradd www
ADD www.conf /etc/php-fpm.d/
EXPOSE 9000
CMD php-fpm -F

# 创建Dockerfile推送的配置文件
vim www.conf
[www]
user = www
group = www
listen = 9000
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
request_terminate_timeout = 0

# 生成PHP镜像
docker build -t "lnmp_php" . 

4. 构建Nginx镜像

# 创建Nginx镜像的Dockerfile
FROM centos:7
COPY nginx.repo /etc/yum.repos.d/
RUN yum makecache
RUN yum -y install nginx
RUN useradd www
ADD default.conf /etc/nginx/conf.d/
ADD nginx.conf /etc/nginx/
EXPOSE 80 443
WORKDIR /root
CMD nginx -g "daemon off;"


# 创建Nginx的yum源文件
vim nginx.conf
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true


# 创建Nginx的主配置文件
vim nginx.conf
user  www;										
worker_processes  auto;						
worker_cpu_affinity auto;								

error_log  /var/log/nginx/error.log notice;				
pid        /var/run/nginx.pid;							
worker_rlimit_nofile 35535;							

events {
    use epoll;										
    worker_connections  10240;							
}

http {
    include       /etc/nginx/mime.types;					
    default_type  application/octet-stream;						

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    log_format json_access '{"@timestamp":"$time_iso8601",'
                      '"host":"$server_addr",'
                      '"clientip":"$remote_addr",'
                      '"size":$body_bytes_sent,'
                      '"responsetime":$request_time,'
                      '"upstreamtime":"$upstream_response_time",'
                      '"upstreamhost":"$upstream_addr",'
                      '"http_host":"$host",'
                      '"url":"$uri",'
                      '"domain":"$host",'
                      '"xff":"$http_x_forwarded_for",'
                      '"referer":"$http_referer",'
                      '"status":"$status"}';

    access_log  /var/log/nginx/access.log  json_access;			

    server_tokens off;									
    client_max_body_size 200m;	
    						
    sendfile        on;								
    tcp_nopush     on;										

    keepalive_timeout  65;							

    gzip on;											
    gzip_disable "MSIE [1-6]\.";								
    gzip_http_version 1.1;										
    gzip_comp_level 2;											
    gzip_buffers 16 8k;										
    gzip_min_length 1024;										
    gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript image/jpeg;			
    include /etc/nginx/conf.d/*.conf;					
}


# 创建Nginx的server文件
vim default.conf
server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;

    root   /usr/share/nginx/html;

    location / {
        index  index.php index.html index.htm;
    }

    location ~ \.php$ {
        fastcgi_pass   php:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

# 生成nginx镜像
docker build -t "lnmp_nginx" . 

5. 下载官网上的MySQL镜像

dokcer pull mysql:5.7 

6. 查看本地所有的镜像

[root@docker01 ~]# docker images
REPOSITORY   TAG       IMAGE ID       CREATED          SIZE
lnmp_php     latest    71403cb24b4d   44 minutes ago   568MB
lnmp_nginx   latest    46461885c43a   46 minutes ago   615MB
mysql        5.7       8cf625070931   10 days ago      448MB
centos       7         8652b9f0cb4c   8 months ago     204MB

7. 创建所有的容器

# 创建Mysql容器
docker run -d -e MYSQL_ROOT_PASSWORD=123 -e MYSQL_DATABASE=wordpress --network lnmp --name mysql mysql:5.7 

# 创建Nginx容器
docker run -d -v /tmp/html:/usr/share/nginx/html --network lnmp --name php  lnmp_php

# 创建PHP容器
docker run -d  -p 80:80 -v /tmp/html/:/usr/share/nginx/html --network lnmp --name nginx lnmp_nginx


# 查看所有正在运行的容器 
[root@docker01 ~]# docker  ps
CONTAINER ID   IMAGE        COMMAND                  CREATED          STATUS          PORTS                                        NAMES
f5ef77c4dfb9   lnmp_nginx   "/bin/sh -c 'nginx -…"   43 minutes ago   Up 43 minutes   0.0.0.0:80->80/tcp, :::80->80/tcp, 443/tcp   nginx
85a54baaf950   lnmp_php     "/bin/sh -c 'php-fpm…"   43 minutes ago   Up 43 minutes   9000/tcp                                     php
cb5a1d14d1e8   mysql:5.7    "docker-entrypoint.s…"   43 minutes ago   Up 43 minutes   3306/tcp, 33060/tcp                          mysql

8. 根据浏览器图形界面提示，创建wp-config.php文件

13. 打开浏览器输入ip: 192.168.15.80
步骤如图所示

14. 创建浏览器指定的wp-config.php文件
[root@docker01 ~]# cd /tmp/html/
# 将浏览器生成的配置文件内容复制到wp-conf.php文件中
[root@docker01 html]# vim wp-config.php
