一.环境及准备工作
1.项目环境
公司在实际的生产环境中，需要使用 Docker 技术在一台主机上创建 LNMP 服务并运行 Wordpress 网站平台。然后对此服务进行相关的性能调优和管理工作。
所有安装包下载：
wget http://101.34.22.188/lnmp_wordpress/mysql-boost-5.7.20.tar.gz
wget http://101.34.22.188/lnmp_wordpress/nginx-1.12.0.tar.gz
wget http://101.34.22.188/lnmp_wordpress/php-7.1.10.tar.bz2
wget http://101.34.22.188/lnmp_wordpress/wordpress-4.9.4-zh_CN.tar.gz
或者
wget -r -np http://101.34.22.188/lnmp_wordpress/
2.服务器环境
| 容器 | 操作系统 | IP地址 | 主要软件 |
|---|---|---|---|
| nginx | CentOS 7 | 172.20.0.10 | Docker-Nginx |
| mysql | CentOS 7 | 172.20.0.20 | Docker-Mysql |
| php | CentOS 7 | 172.20.0.30 | Docker-php |
3.任务需求
（1）使用 Docker 构建 LNMP 环境并运行 Wordpress 网站平台
（2）限制 Nginx 容器最多使用 500MB 的内存和 1G 的 Swap
（3）限制 Mysql 容器写 /dev/sda 的速率为 10 MB/s
（4）将所有容器进行快照，然后将 Docker 镜像打包成 tar 包备份到本地
二.Linux 系统基础镜像
规划三台操作系统的内存及大小4+4G
提前关闭防火墙
#关闭防火墙
systemctl stop firewalld.service
setenforce 0
提前安装好Docker容器，具体安装步骤可以查看以下：
https://blog.csdn.net/Katie_ff/article/details/132304161?spm=1001.2014.3001.5501
下载完之后提前下载centos7的镜像
docker pull centos:7
三.docker构建Nginx
1.建立工作目录上传安装包
mkdir /opt/nginx
cd /opt/nginx
#上传 nginx 安装包 nginx-1.12.0.tar.gz和wordpress 服务包 wordpress-4.9.4-zh_CN.tar.gz
ls
nginx-1.12.0.tar.gz wordpress-4.9.4-zh_CN.tar.gz
2.编写 Dockerfile 脚本
vim Dockerfile
FROM centos:7
MAINTAINER this is nginx image
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:$PATH
ADD nginx.conf /usr/local/nginx/conf/
ADD wordpress-4.9.4-zh_CN.tar.gz /usr/local/nginx/html
RUN chmod 777 -R /usr/local/nginx/html/
EXPOSE 80
VOLUME [ "/usr/local/nginx/html/" ]
CMD [ "/usr/local/nginx/sbin/nginx","-g","daemon off;" ]
3.准备 nginx.conf 配置文件
vim nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
charset utf-8;
location / {
root html;
index index.html index.php;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location ~ \.php$ {
root html;
#此地址是php端地址
fastcgi_pass 172.20.0.30:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
}
}
egrep -v "^(.)*#(.)*$" nginx.conf | grep -v "^$"
4.生成镜像
docker build -t nginx:lnmp .
docker images
5.创建自定义网络
docker network create --subnet=172.20.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetwork
docker network ls
ifconfig docker1
6.启动镜像容器
docker run -d --name nginx -p 80:80 -m 500m --memory-swap 1g --net mynetwork --ip 172.20.0.10 nginx:lnmp
docker ps
docker inspect nginx
7.验证 nginx
#进入容器验证
[root@nginx nginx]# curl http://192.168.245.116:80
Welcome to nginx!
Welcome to nginx!
If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.
For online documentation and support please refer to
nginx.org.
Commercial support is available at
nginx.com.
Thank you for using nginx.
四.docker构建Mysql
1. 建立工作目录
mkdir /opt/mysql
cd /opt/mysql/
#传入mysql安装包mysql-boost-5.7.20.tar.gz
2. 编写 Dockerfile
vim Dockerfile
FROM centos:7
MAINTAINER this is mysql image
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/src/

ADD 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/lib:$PATH
VOLUME [ "/usr/local/mysql" ]
CMD ["/usr/sbin/init"]
3. 准备 my.cnf 文件
vim 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
4. 生成镜像
docker build -t mysql:lnmp .
docker images
5. 启动镜像容器
docker run --name=mysql -d --privileged --device-write-bps /dev/sda:10M -v /usr/local/mysql --net mynetwork --ip 172.20.0.20 mysql:lnmp
docker ps -a
6. 验证 mysql
docker exec -it mysql bash
systemctl status mysqld
五、docker构建Php
1. 建立工作目录
mkdir /opt/php
cd /opt/php/
#传入php安装包php-7.1.10.tar.bz2
2. 编写 Dockerfile 脚本
vim Dockerfile
FROM centos:7
MAINTAINER this is php image
RUN yum install -y gd \
libjpeg libjpeg-devel \
libpng libpng-devel \
freetype freetype-devel \
libxml2 libxml2-devel \
zlib zlib-devel \
curl curl-devel \
openssl openssl-devel \
gcc gcc-c++ make pcre-devel;useradd -M -s /sbin/nologin nginx
ADD php-7.1.10.tar.bz2 /usr/local/src/
WORKDIR /usr/local/src/php-7.1.10
RUN ./configure \

--enable-tokenizer \
--enable-zip ; make -j 4 ; make install
ENV PATH /usr/local/php/bin:/usr/local/php/sbin:$PATH
ADD php.ini /usr/local/php/lib/
ADD php-fpm.conf /usr/local/php/etc/
ADD www.conf /usr/local/php/etc/php-fpm.d/
EXPOSE 9000
CMD /usr/local/php/sbin/php-fpm -F
3. 准备 php.ini、php-fpm.conf、www.conf 配置文件
3.1 php.ini
该配置文件模板位于安装目录的 php-7.1.10/php.ini-development 位置
vim php.ini
#939行,取消注释，修改
date.timezone = Asia/Shanghai
#1170行,修改
mysqli.default_socket = /usr/local/mysql/mysql.sock
egrep -v "^;" php.ini | egrep -v "^$"
3.2 php-fpm.conf
该配置文件位于 /usr/local/php/etc/php-fpm.conf.default
vim php-fpm.conf
#17行，删除注释符号“;”
pid = run/php-fpm.pid
egrep -v "^;" php-fpm.conf | egrep -v "^$"
3.3 www.conf
该配置文件位于 cd /usr/local/php/etc/php-fpm.d/
vim www.conf
user = nginx
group = nginx
#36行，修改监听IP和端口为容器IP:9000端口
listen = 172.20.0.30:9000
egrep -v "^;" www.conf | egrep -v "^$"
[www]
user = nginx
group = nginx
listen = 172.20.0.30:9000

pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
4. 生成镜像
docker build -t php:lnmp .
docker images
5. 启动镜像容器
docker run -itd --name php --net mynetwork --ip 172.20.0.30 -p 9000:9000 --volumes-from nginx --volumes-from mysql php:lnmp
docker ps
6. 验证 php
docker exec -it php bash
ps -aux
六、启动 wordpress 服务
1. mysql 授权
#进入 mysql 容器
docker exec -it mysql bash
mysql -u root -p
Enter password:
#初始密码为空直接回车
mysql> create database wordpress;
Query OK, 1 row affected (0.00 sec)
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';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
2.浏览器访问测试
访问 http://192.168.245.116/wordpress/index.php
