1. 部署步骤与流程

  • 环境准备:

    CentOS 7:内核最好在 4 核以上;内存在 4G 以上;硬盘 60G。

    否则很容易在创建镜像的过程中出错,提示内存不足。


  1.1 关闭防火墙

1 systemctl stop firewalld 
2 systemctl disable firewalld
3 setenforce 0

 

Blog.083 Docker 部署 LNMP + Wordpress_nginx

 


  1.2 安装 Docker

    详见之前的博客:Blog.079 Docker 安装、基本管理与网络模式 


  1.3 Docker 部署 Nginx 

  (容器IP 为 172.18.0.10)

 

1 docker network create --subnet=172.18.0.0/16 --opt "com.docker.network.bridge.name"="docker1"  mynetwork #自定义一个网卡,网卡名为 docker1 ,网络模式 mynetwork, ip地址池172.18.0.0

    可以用 ifconfig docker1 查看是否创建成功。

 

1 mkdir /opt/nginx
2 cd /opt/nginx/
3 
4 ##上传 nginx-1.12.0.tar.gz、wordpress-4.9.4-zh_CN.tar.gz 到 /opt/nginx/ 目录中
5 mkdir /opt/nginx/html
6 tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C /opt/nginx/html

 

1 ##在 /opt/nginx 目录下解压软件包
2 
3 tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C /opt/nginx/html

 

Blog.083 Docker 部署 LNMP + Wordpress_mysql_02

 

  • 在 /opt/nginx 目录下创建
 1 vim Dockerfile
 2 
 3 FROM centos:7
 4 MAINTAINER this is nginx image <abc>
 5 RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make
 6 RUN useradd -M -s /sbin/nologin nginx
 7 ADD nginx-1.12.0.tar.gz /usr/local/src/
 8 WORKDIR /usr/local/src/nginx-1.12.0
 9 RUN ./configure \
10 --prefix=/usr/local/nginx \
11 --user=nginx \
12 --group=nginx \
13 --with-http_stub_status_module && make && make install
14 ENV PATH /usr/local/nginx/sbin:$PATH
15 ADD nginx.conf /usr/local/nginx/conf/
16 ADD wordpress-4.9.4-zh_CN.tar.gz /usr/local/nginx/html/
17 RUN chmod 777 -R /usr/local/nginx/html/
18 EXPOSE 80
19 EXPOSE 443
20 ENTRYPOINT [ "/usr/local/nginx/sbin/nginx", "-g", "daemon off;" ]

 

  • 在 /opt/nginx 目录下,传入其他已经装好的 nginx.conf 文件,并修改如下部分:
 1 worker_processes  1;
 2 events {
 3     worker_connections  1024;
 4 }
 5 http {
 6     include       mime.types;
 7     default_type  application/octet-stream;
 8     sendfile        on;
 9     keepalive_timeout  65;
10     server {
11         listen       80;
12         server_name  localhost;
13 
14         ##配置网页的字符集编码为utf8
15 
16         charset utf8;
17         location / {
18             root   html;
19 
20        ##修改,配合首页文件有 index.php
21 
22             index  index.html index.php;
23         }
24         error_page   500 502 503 504  /50x.html;
25         location = /50x.html {
26             root   html;
27         }
28 
29         ##配置nginx支持php
30 
31         location ~ \.php$ {
32             root           html;
33         ##fastcgi_pass 配置php所在容器的ip以及端口
34 
35             fastcgi_pass   172.18.0.30:9000;
36             fastcgi_index  index.php;
37 
38         ##配置传递脚本文件请求路径。
39              $fastcgi_script_name 前配置的是nginx的网页文件。
40 
41             fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
42             include        fastcgi_params;
43         }
44     }
45 }    

 

  • 构建镜像,success 成功后再创建容器
1 docker build -t nginx:lnmp .
2 
3 docker run -d --name nginx -p 80:80 -v /opt/nginx/html:/usr/local/nginx/html --net mynetwork --ip 172.18.0.10 nginx:lnmp

  1.6 测试访问网页

 1 ##启动容器,需要从nginx容器和mysql容器中获取数据
 2 
 3 docker run --name=php -d -p 9000:9000 --volumes-from mysql --volumes-from nginx --net mynetwork --ip 172.18.0.30 php:lnmp
 4 
 5 ##进入容器,进行用户授权
 6 
 7 docker exec -it mysql /bin/bash
 8 mysql -u root -p mysql
 9 密码直接回车
10 
11 ##进入 MySQL
12 
13 mysql> create database wordpress;
14 Query OK, 1 row affected (0.00 sec)
15 
16 mysql> grant all privileges on wordpress.* to 'wordpress'@'%' identified by '123456';
17 Query OK, 0 rows affected, 1 warning (0.00 sec)
18 
19 mysql> grant all privileges on *.* to 'root'@'%' identified by 'abc123';
20 Query OK, 0 rows affected, 1 warning (0.00 sec)
21 
22 mysql> flush privileges;
23 Query OK, 0 rows affected (0.01 sec)
