< 5 docker-test - [root]: > mkdir -p /apps/compose_lnmp/nginx
< 5 docker-test - [root]: >  cd !$
< 5  docker-test - [root]: /apps/compose_lnmp/nginx >

2、下载nginx软件包，创建dockerfile

< 6  docker-test - [root]: /apps/compose_lnmp/nginx > # wget http://nginx.org/download/nginx-1.14.2.tar.gz

< 7  docker-test - [root]: /apps/compose_lnmp/nginx > # vim Dockerfile

FROM centos:7
MAINTAINER gujiwork
RUN yum install -y gcc gcc-c++ make openssl-devel pcre-devel
ADD nginx-1.14.2.tar.gz /tmp
RUN cd /tmp/nginx-1.14.2 && ./configure --prefix=/usr/local/nginx && make -j 4 && make install
COPY nginx.conf  /usr/local/nginx/conf

EXPOSE 80
WORKDIR /usr/local/nginx
CMD ["./sbin/nginx", "-g", "daemon off;"]

3、这里面用到了nginx.conf，放到compose_lnmp/nginx目录下，将 fastcgi_pass 127.0.0.1:9000改成php容器名， fastcgi_pass php-cgi:9000;

#user  nginx;
worker_processes  2;
worker_cpu_affinity 0101 1010;

#error_log  logs/error.log;
error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {
    worker_connections  10240;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    server_tokens off;  

    #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  logs/access.log  main;

    sendfile        on;
    tcp_nopush on;
    tcp_nodelay on;
    server_names_hash_bucket_size 128;
    server_names_hash_max_size 512;
    client_header_timeout 15s;
    client_body_timeout 15s;
    send_timeout 60s;

    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

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

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {
            root           html;
            fastcgi_pass   php-cgi:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi_params;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }

    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}
include vhost/*.conf;
}

4、创建MySQL目录，数据和配置文件做持久化，这里我们使用mysql官方镜像，因此不需要写dockerfile

< 39  docker-test - [root]: /apps/compose_lnmp > # tree  mysql/
mysql/
|-- conf
|   `-- my.cnf
`-- data

< 40  docker-test - [root]: /apps/compose_lnmp > # cat mysql/conf/my.cnf 
[mysqld]
user=mysql
port=3306
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.socket
pid-file=/var/run/mysql/mysql.pid
log_error=/var/log/mysql/error.log
character_set_server = utf8
max_connections=3600

5、创建php目录及dockerfile，php.ini主要修改了时区为shanghai

< 49  docker-test - [root]: /apps/compose_lnmp > # tree  php/
php/
|-- Dockfile
|-- php-5.6.31.tar.gz
`-- php.ini

< 50  docker-test - [root]: /apps/compose_lnmp > # cat php/Dockfile 
FROM centos:7
MAINTAINER gujiwork
RUN yum install -y gcc gcc-c++ gd-devel libxml2-devel libcurl-devel libjpeg-devel libpng-devel openssl-devel make
ADD php-5.6.31.tar.gz /tmp/
RUN cd /tmp/php-5.6.31 && \
    ./configure --prefix=/usr/local/php \
    --with-config-file-path=/usr/local/php/etc \
    --with-mysql --with-mysqli \
    --with-openssl --with-zlib --with-curl --with-gd \
    --with-jpeg-dir --with-png-dir --with-iconv \
    --enable-fpm --enable-zip --enable-mbstring && \
    make -j 4 && make install && \
    cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf && \
    sed -i "s/127.0.0.1/0.0.0.0/" /usr/local/php/etc/php-fpm.conf && \
    cp ./sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm && \
    chmod +x /etc/init.d/php-fpm 
COPY php.ini /usr/local/php/etc

EXPOSE 9000
CMD /etc/init.d/php-fpm start && tail -F /var/log/messages

6、创建docker-compose维护文件

< 53  docker-test - [root]: /apps/compose_lnmp > # cat docker-compose.yml 
version: '3'
services:
  nginx:
    hostname: nginx
    build:
      context: ./nginx
      dockerfile: Dockerfile
    ports:
      - 80:80
    links:
      - php:php-cgi
    volumes:
      - ./wwwroot:/usr/local/nginx/html

  php:
    hostname: php
    build: ./php
    links:
      - mysql:mysql-db
    volumes:
      - ./wwwroot:/usr/local/nginx/html

  mysql:
    hostname: mysql
    image: mysql:5.6
    ports:
      - 3306:3306
    volumes:
      - ./mysql/conf:/etc/mysql/conf.d
      - ./mysql/data:/var/lib/mysql
    #command: --character-set-server=utf8
    environment:
      MYSQL_ROOT_PASSWORD: 123456
      MYSQL_DATABASE: wordpress
      MYSQL_USER: user
      MYSQL_PASSWORD: user123

7、创建web挂载目录，整体目录结构如下

< 56  docker-test - [root]: /apps/compose_lnmp > # tree .
.
|-- docker-compose.yml
|-- mysql
|   |-- conf
|   |   `-- my.cnf
|   `-- data
|-- nginx
|   |-- Dockerfile
|   |-- nginx-1.14.2.tar.gz
|   `-- nginx.conf
|-- php
|   |-- Dockfile
|   |-- php-5.6.31.tar.gz
|   `-- php.ini
`-- wwwroot

6 directories, 8 files

8、执行build构建镜像

< 81  docker-test - [root]: /apps/compose_lnmp > # docker-compose  build

9、出现success表示构建成功

make[1]: Leaving directory `/tmp/nginx-1.14.2'
Removing intermediate container b7fb79c4671e
---> b756345aac5b
Step 6/9 : COPY nginx.conf /usr/local/nginx/conf

Removing intermediate container a2db489f2b5b
---> 76ae0759f3b1
Successfully built 76ae0759f3b1

10、启动服务测试

< 82  docker-test - [root]: /apps/compose_lnmp > # docker-compose  up -d
Creating network "compose_lnmp_default" with the default driver
