Dockerfile镜像LNMP的实战

一、环境准备

1、关闭防火墙

[root@localhost ~]# systemctl status firewalld.service 
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)
[root@localhost ~]# setenforce 0
setenforce: SELinux is disabled

2、拉取centos:7镜像

[root@localhost ~]# docker pull centos:7
7: Pulling from library/centos
2d473b07cdd5: Pull complete 
Digest: sha256:9d4bcbbb213dfd745b58be38b13b996ebb5ac315fe75711bd618426a630e0987
Status: Downloaded newer image for centos:7
docker.io/library/centos:7
[root@localhost ~]# docker images
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
nginx        latest    d3efa07f874b   3 days ago    132MB
centos       7         eeb6ee3f44bd   4 weeks ago   204MB

3、自定义网络

二、部署nginx（容器IP 为 172.18.0.10）

mkdir /opt/nginx
cd /opt/nginx/

上传 nginx-1.12.0.tar.gz、wordpress-4.9.4-zh_CN.tar.gz 到 /opt/nginx/ 目录中
mkdir /opt/nginx/html
tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C /opt/nginx/html

vim Dockerfile

FROM centos:7
MAINTAINER this is nginx image <wl>
RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make
RUN 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 && 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
EXPOSE 443
ENTRYPOINT [ "/usr/local/nginx/sbin/nginx", "-g", "daemon off;" ]


docker build -t nginx:lnmp .

docker run -d --name nginx -p 80:80 -v /opt/nginx/html:/usr/local/nginx/html --net mynetwork --ip 172.18.0.10 nginx:lnmp　　

 

三、部署mysql（容器IP 为 172.18.0.20） 

mkdir /opt/mysqld
cd /opt/mysqld

上传 mysql-boost-5.7.20.tar.gz 到 /opt/mysqld 目录中

vim Dockerfile

FROM centos:7
MAINTAINER this is mysql image <wl>
RUN yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake make
RUN 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 \

RUN chown -R mysql:mysql /usr/local/mysql/
ADD my.cnf /etc/my.cnf
RUN chown mysql:mysql /etc/my.cnf
ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
WORKDIR /usr/local/mysql/
RUN bin/mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
RUN cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
EXPOSE 3306
RUN systemctl enable mysqld
VOLUME [ "/usr/local/mysql" ]
CMD /usr/sbin/init

 

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

[mysql]
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
server-id = 1

docker build -t mysql:lnmp .

docker run --name=mysql -d --privileged -v /usr/local/mysql --net mynetwork --ip 172.18.0.20 mysql:lnmp /usr/sbin/init　　

四、部署php（容器IP 为 172.18.0.30） 

mkdir /opt/php
cd /opt/php

上传 php-7.1.10.tar.bz2 到 /opt/php 目录中

vim Dockerfile

FROM centos:7
MAINTAINER this is php image <wl>
RUN yum -y install gd \
