Docker构建之旅
　　##构建三个docker，php、nginx、mysql三个镜像
###1，先从docker仓库里面拉取centos镜像，和mysql镜像

docker pull docker.io/centos
docker pill docker.io/mysql
　　###2，创建一个网络，我们一会使用这个网络进行container之间的联系。
docker network create --subnet 172.16.1.0/24 testnetwork
　　###3，构建nginx的Dockerfile文件

[root@Docker docker_file]# vim Dockerfile_nginx
FROM centos
VOLUME ["/code"]
COPY ./nginx.repo /etc/yum.repos.d/
RUN yum clean all && \
yum -y install nginx  httpd-tools && \
yum clean all && \
htpasswd -b -c /etc/http_blog.pass zsf zsf && \
groupadd -g 8888 www && useradd -u 8888 -g www -M -s /sbin/nologin www
COPY nginx.conf /etc/nginx/nginx.conf
COPY blog.sentinel.conf /etc/nginx/conf.d/
COPY edu.sentinel.conf /etc/nginx/conf.d/
COPY lt.sentinel.conf /etc/nginx/conf.d/
EXPOSE 80 81 82
CMD ["nginx","-g","daemon off;"]
　　###4，构建php的Dockerfile文件

[root@Docker docker_file]# vim php_file
FROM centos
RUN rpm -Uvh http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm && \
rpm -Uvh http://mirror.webtatic.com/yum/el7/webtatic-release.rpm && \
yum -y install php71w php71w-cli php71w-common php71w-devel \
php71w-embedded php71w-gd php71w-mcrypt php71w-mbstring \
php71w-pdo php71w-xml php71w-fpm php71w-mysqlnd php71w-opcache \
php71w-pecl-memcached php71w-pecl-redis php71w-pecl-mongodb httpd-tools && \
yum clean all && groupadd -g 8888 www && useradd -u 8888 -g www -M -s /sbin/nologin www
COPY www.conf /etc/php-fpm.d/
COPY php-fpm.conf /etc/
EXPOSE 9000
CMD ["/usr/sbin/php-fpm"]
　　###5，在Nginx里面配置了三个web服务，分别是blog，edu，lt，构建对应的配置文件
nginx的主配置文件
```nginx.conf
　　[root@Docker docker_file]# cat nginx.conf
　　user  www;
worker_processes  1;
　　error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;
　　events {
worker_connections  1024;
}
　　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"';

access_log  /var/log/nginx/access.log  main;
sendfile        on;
#tcp_nopush     on;
keepalive_timeout  65;
#gzip  on;
include /etc/nginx/vhost/*.conf;
include /etc/nginx/conf.d/*.conf;
　　}


**blog站点的配置文件**
```nginx.conf
[root@Docker docker_file]# cat blog.sentinel.conf
server {
listen 80;
server_name 10.0.0.107;
root /code/wordpress;
access_log /var/log/nginx/blog.access.log main;
index index.php;
client_max_body_size 300m;
location  ~* \.php$ {
root /code/wordpress;
fastcgi_pass 172.16.1.100:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~* ^/wp-admin {
auth_basic "please user password";
auth_basic_user_file /etc/http_blog.pass;
index index.php;
}   
}
　　edusoho--nginx的配置文件
　　```nginx.conf
[root@Docker docker_file]# cat edu.sentinel.conf
server {
listen 81;

server_name 172.16.1.7;
client_max_body_size 300m;
root /code/edusoho/web;
access_log /var/log/nginx/edu.sentinel.org.log;
error_log /var/log/nginx/edu.sentinel.org.log;
location / {
index app.php;
try_files $uri @rewriteapp;
}
location @rewriteapp {
rewrite ^(.*)$ /app.php/$1 last;
}
location ~ ^/udisk {
internal;
root /code/edusoho/app/data/;
}
location ~ ^/(app|app_dev)\.php(/|$) {
fastcgi_pass   172.16.1.100:9000;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  HTTPS              off;
fastcgi_param HTTP_X-Sendfile-Type X-Accel-Redirect;
fastcgi_param HTTP_X-Accel-Mapping /udisk=/code/edusoho/app/data/udisk;
fastcgi_buffer_size 128k;
fastcgi_buffers 8 128k;
}
location ~ ^/files/.*\.(php|php5)$ {
deny all;
}
location ~ \.php$ {
fastcgi_pass   172.16.1.100:9000;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  HTTPS              off;
}
　　}


**lt的nginx配置文件**
```nginx
[root@Docker docker_file]# cat lt.sentinel.conf
server {
listen 82;
server_name 172.16.1.7;
root /code/lt;
index index.php;
location ~* \.php$ {
root /code/lt;
fastcgi_pass 172.16.1.100:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_index index.php;
include fastcgi_params;
}
}
6，php的相关配置文件
　　php的主配置文件
　　```nginx.conf
[root@Docker docker_file]# cat php-fpm.conf
daemonize = no


**www.conf的配置文件**
```nginx.conf
[root@Docker docker_file]# cat www.conf | grep -E "user|group|listen"
user = www
group = www
listen = 172.16.1.100:9000
listen.allowed_clients = 172.16.1.5
　　##然后开始构建镜像
构建nginx的镜像
[root@Docker docker_file]# docker build -f Dockerfile_nginx -t nginx/php:1.5 .
　　构建php代码
[root@Docker docker_file]# docker build -f php_file -t php:8.8 .

运行docker镜像，测试结果
　　构建一个nginx的容器container
[root@Docker docker_file]# docker run -d --network testnetwork --ip 172.16.1.5 -p 10.0.0.250:80-82:80-82 -v /code:/code --name nginx nginx/php:1.5
构建完成之后执行命令
[root@Docker docker_file]# docker exec -it nginx chown -R www.www /code
　　构建一个PHP的容器container
[root@Docker docker_file]# docker run -d --volumes-from nginx -p 9000:9000 --network testnetwork --ip 172.16.1.100 --name php php:8.8
　　构建mysql镜像
[root@Docker tmp]# docker run -it --network testnetwork --ip 172.16.1.10 --name mysql -v /data/db/mariadb:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d docker.io/mysql

root@6106cebefb38:/# mysql -uroot -p
