一、基础环境准备
| 容器 | 系统 | IP地址 | 软件 |
|---|---|---|---|
| nginx | centos 7.5 | 172.18.0.10 | wordpress-6.0.2-zh_CN.tar.gz、nginx-1.12.2.tar.gz |
| mysql | centos 7.5 | 172.18.0.20 | mysql-boost-5.7.25.tar.g |
| php | centos 7.5 | 172.18.0.30 | php-7.1.24.tar.gz |
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
#关闭防火墙和核心防护
docker pull centos:7
#从docker Hub公共仓库下载基础镜像
docker network create --subnet=172.18.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetwork
#设置自定义网络模式，模式为bridge模式，docker1的ip地址为172.18.0.1，显示的网络名称mynetwork。
docker network ls
#查看使用的网络模式
ifconfig
二、部署nginx（容器IP为172.18.0.10）
1、整个Dockerfile文件内容
mkdir /opt/nginx
cd /opt/nginx
#此目录上传nginx包
vim Dockerfile
#编写dockerfile文件
FROM centos:7
#指定基础镜像
MAINTAINER ydq
#指定维护者信息
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make
#安装依赖包，安装环境
RUN useradd -M -s /sbin/nologin nginx
#创建nginx用户
ADD nginx-1.12.2.tar.gz /opt
#将本地安装包上传到指定目录(自动解压)
WORKDIR /opt/nginx-1.12.2
#进入到/opt/nginx-1.12.2目录中
RUN ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module && make && make install
#开始编译安装,加上&&符号，只有前面执行完成，后面才会执行
ENV PATH=/usr/local/nginx/sbin:$PATH
#将nginx执行命令放入到环境变量中
ADD nginx.conf /usr/local/nginx/conf/nginx.conf
#在宿主机写好配置文件，然就将配置文件复制到容器中
ADD wordpress-6.0.2-zh_CN.tar.gz /usr/local/nginx/html
#上传论坛的包
RUN chmod 777 -R /usr/local/nginx/html
#给html文件所有权限
EXPOSE 80
#开放80端口
VOLUME ["/usr/local/nginx/html/"]
#挂载目录(相当于将/usr/local/nginx/html目录共享，会在宿主机上自动生成共享目录，主要目的是为了让容器之间共享这个文件)
CMD ["/usr/local/nginx/sbin/nginx","-g","daemon off;"]
#执行启动nginx命令,并且关闭nginx的后台启动，因为需要它占用前台，让docker不关闭。
2、配置nginx.conf文件
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
charset utf-8;
location / {
root html;
index index.html index.php;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location ~ \.php$ { #当访问以.php结尾的URL时，会连接到172.18.0.30的ip地址上
root html;
fastcgi_pass 172.18.0.30:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
}
}
3、构建镜像
在构建镜像前，确保一下文件压缩包都在。
docker build -t nginx:lnmp .
#构建nginx镜像(别忘记最后的点)
docker images
#查看镜像
docker run -d --name nginx -p 80:80 -m 500m --memory-swap 1g --net mynetwork --ip 172.18.0.10 nginx:lnmp
#启动容器
----------------------------
-m 500: #表示该容器内存最大为500MB
--memory-swap: #表示内存+swap总共1G，那swap也是500MB
//相当于是限制了内存的使用量，避免所占资源太多
----------------------
docker ps -a
#查看容器
curl 20.0.0.55
三、部署mysql
1、整个Docker文件内容
mkdir /opt/mysql
cd /opt/mysql
#上传mysql包到此目录下
vim Dockerfile
FROM centos:7
#基础镜像
MAINTAINER ydq
#维护人信息
RUN yum -y install ncurses ncurses-devel bison cmake pcre-devel zlib-devel gcc gcc-c++ make
#安装环境
RUN useradd -M -s /sbin/nologin mysql
#创建mysql用户
ADD mysql-boost-5.7.25.tar.gz /opt
#将mysql安装包上传(自带boost)
WORKDIR /opt/mysql-5.7.25
#切换到mysql解压后的目录
RUN cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS=all \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1 && make -j4 && make install
#编译安装
EXPOSE 3306
#开放端口
RUN chown -R mysql:mysql /usr/local/mysql/;chown mysql:mysql /etc/my.cnf
#设置权限
ENV PATH /usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
#设置环境变量
WORKDIR /usr/local/mysql/bin
#切换目录
RUN ./mysql \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
#初始化mysql
RUN cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
#复制mysql服务程序到启动文件中
VOLUME ["/usr/local/mysql"]
#设置共享目录
CMD ["/usr/sbin/init"]
#启动容器之后，可以使用systemctl工具(并且占用前台，保持容器不断)
2、准备my.conf文件
vim /opt/my.cnf
[client]
port = 3306
default-character-set=utf8
socket=/usr/local/mysql/mysql.sock
[mysql]
port = 3306
default-character-set=utf8
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 = 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
3、生成镜像
docker build -t mysql:lnmp .
#生成镜像
docker images
#查看镜像
4、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 172.18.0.20 mysql:lnmp
#生成容器
-----------------------------------------
--privileged: #让容器内拥有root权限
--device-write-bps: #限制写入到/dev/sda中每秒最大10M的速度。
-v /usr/local/mysql: #共享这个目录，其它容器可以使用--volumes-from 指定读取本容器的共享目录。然后也会生成一样的目录。
--net mynetwork: #指定--net网络模式，mynetwork为自定义网络模式。
--ip 172.18.0.20: #指定ip地址，自定义网络模式也可以指定ip地址。
-----------------------------------------
docker ps -a
#查看容器
5、验证mysql
docker exec -it mysql bash
#登录该容器
systemctl status mysqld
#查看mysql状态
四、PHP部署
1、整个Dockerfile文件内容
mkdir /opt/php
cd /opt/php
#将php包上传到该目录
