docker ——dockerfile镜像构建LNMP

(目录)

一、构建自定义docker网络

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
 
docker network create --subnet=172.18.0.0/16 --opt "com.docker.network.bridge.name"="docker1"  mynetwork

二、构建nginx容器（172.18.0.10）

1.mkdir /opt/nginx
cd /opt/nginx/
把nginx-1.12.0.tar.gz和wordpress-4.9.4-zh_CN.tar.gz安装包移进来
mkdir /opt/nginx/html
tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C /opt/nginx/html
 
2.vim Dockerfile
 
#基于基础镜像
FROM centos:7
#用户信息
MAINTAINER this is nginx image <gxs>
#添加环境包
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make
RUN useradd -M -s /sbin/nologin nginx
#上传nginx软件压缩包，并解压
ADD nginx-1.12.0.tar.gz /usr/local/src/
#指定工作目录
WORKDIR /usr/local/src/nginx-1.12.0
RUN ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module && make && make install
ENV PATH /usr/local/nginx/sbin:$PATH      #指定路径
ADD nginx.conf /usr/local/nginx/conf/     #指定修改后的nginx配置文件
ADD wordpress-4.9.4-zh_CN.tar.gz /usr/local/nginx/html/ #指定网页内容
RUN chmod 777 -R /usr/local/nginx/html/
EXPOSE 80                 #指定http端口
EXPOSE 443                #指定https端口
CMD nginx -g "daemon off;"
 
3.修改nginx配置文件（与php对接）
在本机或者其他主机安装nginx，把nginx配置文件移进本机
vim nginx.conf
...
location / {
            root   html;
            index  index.html index.php;
        }
...
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;
        }
...
 
4.创建新镜像
docker build -t nginx:lnmp .
 
5.启动容器
docker run -d --name nginx -p 80:80 -m 500m --memory-swap 1g -v /opt/nginx/html:/usr/local/nginx/html --net mynetwork --ip 172.18.0.10 nginx:lnmp    #限制Nginx容器最多使用500Mb的内存和1G的Swap

==在本机或者其他主机安装nginx，把nginx配置文件移进本机（nginx.conf）== 创建新镜像

三、构建mysql（172.18.0.20）

1.mkdir /opt/mysql
cd /opt/mysql
把boost_1_59_0.tar.gz和mysql-5.7.17.tar.gz移动到本目录
 
2.vim Dockerfile
 
FROM centos:7
MAINTAINER this is mysql image <lnmp>
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/
WORKDIR /usr/local/src/mysql-5.7.20/
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
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.在当前目录创建mysql配置文件
vim 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
 
[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
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.创建新镜像
docker build -t mysql:lnmp .
 
5.启动容器，并进行初始化
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

四、构建php（172.18.0.30）

1.mkdir /opt/php
cd /opt/php
上传 php-7.1.10.tar.bz2 到/opt/php目录中
 
2.vim Dockerfile
 
FROM centos:7
MAINTAINER this is php image <gxs>
RUN yum -y install 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
RUN 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 \
--prefix=/usr/local/php \
--with-mysql-sock=/usr/local/mysql/mysql.sock \
--with-mysqli \
--with-zlib \
--with-curl \
--with-gd \
--with-jpeg-dir \
--with-png-dir \
--with-freetype-dir \
--with-openssl \
--enable-fpm \
--enable-mbstring \
--enable-xml \
--enable-session \
--enable-ftp \
--enable-pdo \
--enable-tokenizer \
--enable-zip && make && 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.创建新镜像
docker build -t php:lnmp .
 
4.创建新容器
docker run --name=php -d -p 9000:9000 --volumes-from mysql --volumes-from nginx --net mynetwork --ip 172.18.0.30 php:lnmp

准备php.ini、php-fpm.conf、www.conf配置文件

从其他机器安装php后，scp配置文件到容器宿主机并进行修改 php.ini

[root@docker php]# 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

php-fpm.conf

[root@docker php]# vim php-fpm.conf
 
#17行，删除注释符号“;”
pid = run/php-fpm.pid

www.conf

[root@docker php]# vim www.conf
 
#23、24行，修改用户和组
user = nginx
group = nginx
#36行，修改监听IP和端口为容器IP:9000端口
listen = 172.111.0.30:9000

五、进入数据库容器给与权限

docker exec -it mysql /bin/bash
 
mysql
create database wordpress;
grant all privileges on wordpress.* to 'wordpress'@'%' identified by 'zxc123';
grant all privileges on *.* to 'root'@'%' identified by 'zxc123';
flush privileges;

六、浏览器访问
