Docker搭建LNMP+Wordpress的实验

[root@docker ~]# systemctl disable --now firewalld
[root@docker ~]# setenforce 0
setenforce: SELinux is disabled
[root@docker ~]# docker pull centos
#从公有仓库中下载 centos7 作为系统基础镜像
[root@docker ~]# docker images

三、部署Nginx

1、建立工作目录

[root@docker ~]# mkdir /opt/nginx
[root@docker ~]# cd /opt/nginx
[root@docker nginx]# rz -E
rz waiting to receive.
#上传 nginx 安装包 nginx-1.12.0.tar.gz
[root@docker nginx]# rz -E
rz waiting to receive.
#上传 wordpress 服务包 wordpress-4.9.4-zh_CN.tar.gz

2、编写Dockerfile

[root@docker nginx]# vim Dockerfile
 
FROM centos:7
MAINTAINER this is nginx image <lnmp>
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make;useradd -M -s /sbin/nologin nginx
ADD nginx-1.12.0.tar.gz /usr/local/src/
WORKDIR /usr/local/src/nginx-1.12.0
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
ADD nginx.conf /usr/local/nginx/conf/
ADD wordpress-4.9.4-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;" ]

3、准备nginx.conf配置文件

[root@docker nginx]# ls
Dockerfile  nginx-1.12.0.tar.gz  nginx.conf  wordpress-4.9.4-zh_CN.tar.gz
[root@docker nginx]# egrep -v "^(.)*#(.)*$" nginx.conf | grep -v "^$"
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    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;
        }
    }
}

4、设置自定义网段和创建镜像和容器

docker network create --subnet=172.111.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetwork
 
docker network ls
查看
[root@docker nginx]# docker build -t nginx:lnmp .
[root@docker nginx]# docker images

5、启动镜像容器

[root@benet23 nginx]# docker run -d --name nginx -p 80:80 -m 500m --memory-swap 1g --net mynetwork --ip 172.111.0.10 nginx:lnmp
24cbedd7982b1cf658cff4efd1ea75a5bfe252b6d01b2a222ed4cde63215479d
[root@benet23 nginx]# docker ps
CONTAINER ID   IMAG
