基于dockerfile搭建LNMP

组件	自定义IP	所需组件
nginx	172.111.0.10	nginx+wordpress
mysql	172.111.0.20	mysql-5.7.20
php	172.111.0.30	php

LNMP介绍

L：Linux平台，操作系统，另外桑组件的运行平台

N：nginx 提供前端页面

M：MySQL，开源关系的数据库，主要是用来保存用户账号信息。

P：PHP，开发一种动态页面的编程语言，解释解析动态页面，起到中间件的作用。（nginx和数据库的中间，沟通nginx和数据库，已请求数据库上的信息）

lnmp：企业网站的应用模式之一。早期的论坛架构就是lnmp搭建的

实验部署

systemctl stop firewalld
setenforce 0
关闭防火墙和安全机制


cd /opt
mkdir nginx mysql php
cd nginx
拖入nginx   wordpress

vim Dockerfile

声明基础镜像
FROM centos:7

RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make && useradd -M -s /sbin/nologin nginx

ADD nginx-1.22.0.tar.gz /usr/local/src/

指定工作目录
WORKDIR /usr/local/src/nginx-1.22.0

配置和编译安装
RUN ./CONFIG \
--prefix=/usr/local/nginx \
user=nginx \
--group=nginx \
--with-http_stub_status_module && make -j 4 && make install


添加环境变量
ENV PATH /use/local/nginx/sbin:$PATH

接下来多开一个终端去配置nginx.conf文件

开另一个终端
vim nginx.conf

COPY nginx.conf /usr/local/nginx/conf/ 
ADD wordpress-6.4.2-zh_CN.tar.gz /usr/local/nginx/html
EXPOSE 80

创建容器内的数据卷，即可以对外给宿主机挂载，也可以对内给容器使用
VOLUME ["/usr/local/nginx/html"]

设定容器启动时的命令
CMD ["/usr/local/nginx/sbin/nginx","-g","daemon off;"]

wq！

镜像文件配置完毕，接下来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

docker build -t nginx:lnmp .

docker images

docker run -itd --name nginx -p 80:80 -v /opt/nginx:/opt/nginxlogs --network mynetwork --ip 172.111.0.10 nginx:lnmp

docker ps
curl 20.0.0.20
浏览器访问

nginx部署到此结束，下面我们来部署mysql

mysql的dockerfile

FROM centos:7
RUN yum -y install ncurses ncurses-devel bison cmake pcre-devel zlib-devel gcc gcc-c++ make &&\
useradd -M -s /sbin/nologin mysql
ADD mysql-boost-5.7.20.tar.gz /usr/local/scr/

-DWITH_SYSTEMD=1 && make -j 4 && make install
COPY my.cnf /etc/my.cnf
EXPOSE 3306
RUN chown -R mysql:mysql /usr/local/mysql && chown mysql:mysql /etc/my.cnf
WORKDIR /usr/local/mysql/bin/
RUN ./mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data && cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/ && systemctl enable mysqld
ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/bin:$PATH
VOLUME ["/usr/local/mysql"]
ENTRYPOINT ["/usr/sbin/init"]

mysql的my.cnf

[client]
port = 3306
socket=/usr/local/mysql/mysql.sock

 [mysqld]
user = mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port = 3306
character-set-server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket=/usr/local/mysql/mysql.sock
bind-address = 0.0.0.0
skip-name-resolve
max_connections=2048
default-storage-engine=INNODB
max_allowed_packet=16M
server-id = 1

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES

配置文件都配置完成，接下来就是创建镜像，容器（基于自定义网段）

docker run -itd --name mysql -p 3306:3306 --privileged -v /opt/mysql1:/opt/mysql --net mywork --ip 171.111.0.20 mysql:lnmp


docker exec -it mysql bash

最后，给数据库赋权

mysql> grant all privileges on wordpress.* to 'wordpress'@'%' identified by '123456';
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> grant all privileges on *.* to 'root'@'%' identified by '123456' 56';
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

到此，mysql部分配置完成

; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load balancing);
; - trigger alerts for the operating team (24/7).

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: you can prefix with '$prefix' to chroot to the pool prefix or one
; of its subdirectories. If the pool prefix is not set, the global prefix
; will be used instead.
; Note: chrooting is a great security feature and should be used whenever
;       possible. However, all PHP paths will be relative to the chroot
;       (error_log, sessions.save_path, ...).
; Default Value: not set

;catch_workers_output = yes

; Clear environment in FPM workers
; Prevents arbitrary environment variables from reaching FPM worker processes
; by clearing the environment in workers before env vars specified in this
; pool configuration are added.
; Setting to "no" will make all environment variables available to PHP code
; via getenv(), $_ENV and $_SERVER.
; Default Value: yes
;clear_env = no

; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; execute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
;security.limit_extensions = .php .php3 .php4 .php5 .php7

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.

;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp

; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
;   php_value/php_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call 'ini_set'.
;   php_admin_value/php_admin_flag - these directives won't be overwritten by
;                                     PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite previously defined php.ini values, but will append the new value
; instead.

; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr/local/php)

; Default Value: nothing is defined by default except the values in php.ini and
;                specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
;php_flag[display_errors] = off
;php_admin_value[error_log] = /var/log/fpm-php.www.log
;php_admin_flag[log_errors] = on
;php_admin_value[memory_limit] = 32M

php.ini----主配置文件

--1170行--修改
mysqli.default_socket = /usr/local/mysql/mysql.sock
--939行--取消注释，修改
date.timezone = Asia/Shanghai

以上php的配置文件完成，接下来就是创建 镜像和容器

docker build -t php:lnmp .

docker run -itd --name php -p 9000:9000 --volumes-from nignx --volumes-from mysql --network --ip 172.111.0.30 php:lnmp


docker exec -it php bash

最后去浏览器登录

至此，论坛搭建完毕
