一、项目介绍

1.1、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/

1.2、 服务器环境

容器 操作系统 IP地址 主要软件

nginx	CentOS 7.9 x86_64	172.111.0.10	Docker-Nginx
mysql	Centos 7.9 x86_64	172.111.0.20	Docker-Mysql
php	Centos 7.9 x86_64	172.111.0.30	Docker-php
宿主机	Centos 7.9 x86_64	192.168.11.11	Docker 19.03

1.3、 任务需求

• 使用 Docker 构建 LNMP 环境并运行 Wordpress 网站平台。
• 限制 Nginx 容器最多使用 500MB 的内存和 1G 的 Swap。
• 限制 Mysql 容器写 /dev/sda 的速率为 10 MB/s。
• 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。

[root@docker ~]# systemctl disable --now firewalld
[root@docker ~]# setenforce 0
setenforce: SELinux is disabled
[root@docker ~]# docker pull centos:7
#从公有仓库中下载 centos7 作为系统基础镜像
[root@docker ~]# docker images
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
centos       7         eeb6ee3f44bd   4 weeks ago   204MB

二、部署Nginx

2.1、建立工作目录

在docker容器中拉取centoos7作为基础镜像
docker pull centos：7[root@localhost ~]$ mkdir /opt/nginx[root@localhost ~]$ cd /opt/nginx/[root@localhost /opt/nginx]$ lsnginx-1.24.0.tar.gz

2.2、 编写 Dockerfile 脚本

[root@localhost /opt/nginx/html]$ touch Dockerfile
[root@localhost /opt/nginx/html]$ ls
Dockerfile  wordpress[root@docker nginx]# vim Dockerfile
FROM centos:7 AS first
MAINTAINER this is nginx image <wl 20231021>ADD nginx-1.24.0.tar.gz /opt/
RUN yum -y install pcre-devel zlib-devel openssl-devel gcc gcc-c++ make && \
useradd -M -s /sbin/nologin nginx && \
cd /opt/nginx-1.24.0 && \
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module && \
make && \
make installFROM centos:7
COPY --from=first /usr/local/nginx/ /usr/local/nginx/
RUN useradd -M -s /sbin/nologin nginxEXPOSE 80
EXPOSE 443CMD ["/usr/local/nginx/sbin/nginx", "-g", "daemon off;"]

2.3、准备 nginx.conf 配置文件

vim nginx.conf#user  nobody;
worker_processes  2;#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;#pid        logs/nginx.pid;events {use epollworker_connections  1024;
}http {include       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  logs/access.log  main;sendfile        on;#tcp_nopush     on;#keepalive_timeout  0;keepalive_timeout  65;#gzip  on;server {listen       80;server_name  www.byyb;charset utf-8;#access_log  logs/host.access.log  main;location / {root   html;index  index.php index.html;}#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   172.18.0.30:9000;fastcgi_index  index.php;fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$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;#    }#}}

2.4、生成镜像

[root@docker nginx]# docker build -t nginx:lnmp .
[root@docker nginx]# docker images
REPOSITORY   TAG       IMAGE ID       CREATED         SIZE
nginx        lnmp      35a6404fcfa1   5 seconds ago   522MB
centos       7         eeb6ee3f44bd   4 weeks ago     204MB

2.5、创建自定义网络

docker network create --subnet=172.18.0.0/16 --opt "com.dockerwork.bridge.name"="docker1"  lnmpnetwork启动镜像容器
docker run -d --name nginx -p 80:80 -v /opt/nginx/html/:/usr/local/nginx/html/ -v /opt/nginx/nginx.conf:/usr/local/nginx/conf/nginx.conf --network lnmpnetwork --ip 172.18.0.10 nginx:lnmp

三、部署Mysql

3.1、建立工作目录

[root@docker nginx]# mkdir /opt/mysql
[root@docker nginx]# cd /opt/mysql/
[root@docker mysql]# rz -E
rz waiting to receive.
#传入mysql安装包mysql-boost-5.7.41.tar.gz

3.2、编写 Dockerfile

[root@docker mysql]# vim Dockerfile FROM centos:7 AS first
MAINTAINER this is mysql image <wl 20231021>
ADD mysql-boost-5.7.41.tar.gz /opt/
RUN yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake make openssl-devel && \
cd /opt/mysql-5.7.41/ && \
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \

-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1 && make -j 2 && make installFROM centos:7
COPY --from=first /usr/local/mysql/ /usr/local/mysql/
ADD myf /etc/myf
ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
RUN useradd -M -s /sbin/nologin  mysql && \
chown mysql:mysql /etc/myf && \
chown -R mysql:mysql /usr/local/mysql/ && \
/usr/local/mysql/bin/mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
EXPOSE 3306
CMD ["/usr/local/mysql/bin/mysqld"]

3.3、准备 myf 文件

[root@docker mysql]# vim myf[client]
port = 3306
socket=/usr/local/mysql/mysql.sock[mysql]
port = 3306
socket = /usr/local/mysql/mysql.sock
auto-rehash[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 = 1sql_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

3.4、创建镜像

docker build -t mysql:lnmp .
#名称:标签

3.5、 使用新的镜像运行容器并测试

docker run -d --name mysql --privileged -v /usr/local/mysql --network lnmpnetwork --ip 172.18.0.20 mysql:lnmp- `--name=mysql`：指定容器的名称为mysql。
- `-d`：以后台模式运行容器。
- `--privileged`：在容器内部启用特权模式，可以执行一些底层操作。
- `-v /usr/local/mysql`：将宿主机的`/usr/local/mysql`目录挂载到容器的相应位置。
- `--net mynetwork`：将容器连接到名为mynetwork的网络。

四、部署PHP

4.1、创建工作目录并上传代码包

mkdir /opt/php
cd /opt/php上传 php-7.1.10.tar.bz2 到 /opt/php 目录中

4.2、 编写 Dockerfile 脚本

vim DockerfileFROM centos:7 AS first
MAINTAINER this is php image <wl 20231021>
ADD php-7.1.10.tar.bz2 /opt/
RUN yum -y install gd \

cp /opt/php-7.1.10/php.ini-development /usr/local/php/lib/php.ini && \
sed -i -e '939c date.timezone = Asia/Shanghai'  -e '1170c mysqli.default_socket = /usr/local/mysql/mysql.sock' /usr/local/php/lib/php.ini && \
cd /usr/local/php/etc/ && \
cp  php-fpm.conf.default php-fpm.conf && \
sed -i '17 s/^;//' php-fpm.conf && \

cp www.conf.default www.conf && \
sed -i -e '23c user = nginx' -e '24c group = nginx' -e '36c listen = 172.18.0.30:9000' -e '62c listen.allowed_clients = 172.18.0.10' www.confFROM centos:7
COPY --from=first /usr/local/php/ /usr/local/php/
RUN yum -y install gd \
libjpeg-devel \
libpng-devel \
freetype-devel \
libxml2-devel \
zlib-devel \

openssl-devel && \
useradd -M -s /sbin/nologin nginx && \
rm -rf /var/cache/yum/*
EXPOSE 9000
