1 搭建私有镜像仓库
1) 拉起镜像仓库
docker run -d \
-v /opt/registry:/var/lib/registry \
-p 5000:5000 \
--restart=always \
--name registry \
registry
2）修改配置仓库是之能够被我们使用
vi /etc/docker/daemon.json
{"registry-mirrors": ["http://04be47cf.m.daocloud.io"],"insecure-registries":["192.168.184.130:5000"]}
systemctl daemon-reload
systemctl restart docker
3）测试仓库是否可用
curl http://192.168.184.130:5000/v2/_catalog
{"repositories":[]} 说明成功2 创建镜像构建目录
mkdir /tmp/php
3 下载php软件包
wget http://cn2.php.net/distributions/php-7.1.5.tar.gz -P /tmp/php
4 编写Dockerfile文件
cd /tmp/php cat Dockerfile FROM centos:7 MAINTAINER swift RUN yum install -y install epel-release && \ yum -y install git wget lrzsz vim libxml2 libxml2-devel openssl openssl-devel curl curl-devel libjpeg-turbo libjpeg-turbo-devel libpng-devel libpng freetype-devel freetype icu libicu-devel libicu libmcrypt libmcrypt-devel libxslt libxslt-devel php-MySQL && \ yum -y groupinstall "Development Tools" && \ yum provides "*/applydeltarpm" && \ yum install deltarpm -y && \ yum clean all && \ groupadd www && \ useradd -g www www ADD php-7.1.5.tar.gz /usr/local/src/ RUN cd /usr/local/src/php-7.1.5 && \ ./configure --prefix=/usr/local/php71 \ --with-config-file-path=/usr/local/php71/etc \ --with-config-file-scan-dir=/usr/local/php71/conf.d \ --enable-fpm --with-fpm-user=www \ --with-fpm-group=www \ --with-mysql=mysqlnd \ --with-mysqli=mysqlnd \ --with-pdo-mysql=mysqlnd \ --with-iconv-dir \ --with-freetype-dir=/usr/local/freetype \ --with-jpeg-dir \ --with-png-dir \ --with-zlib \ --with-libxml-dir=/usr \ --enable-xml \ --disable-rpath \ --enable-bcmath \ --enable-shmop \ --enable-sysvsem \ --enable-inline-optimization \ --with-curl \ --enable-mbregex \ --enable-mbstring \ --with-mcrypt \ --enable-ftp \ --with-gd \ --enable-gd-native-ttf \ --with-openssl \ --with-mhash \ --enable-pcntl \ --enable-sockets \ --with-xmlrpc \ --enable-zip \ --enable-soap \ --with-gettext \ --disable-fileinfo \ --enable-opcache \ --enable-intl \ --with-xsl && \ make -j 4 && make install && \ cp /usr/local/php71/etc/php-fpm.conf.default /usr/local/php71/etc/php-fpm.conf && \ cp ./php.ini-production /usr/local/php71/etc/php.ini && \ cp /usr/local/php71/etc/php-fpm.d/www.conf.default /usr/local/php71/etc/php-fpm.d/www.conf && \ cp ./sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm && \ chmod +x /etc/init.d/php-fpm && \ rm -rf /usr/loacl/src/php-7.1.5 EXPOSE 9000 CMD ["/etc/init.d/php-fpm","start"]
5 构建php镜像
docker build -t 192.168.184.130:5000/lnmp-7-php71:base .
6 查看查看已经构建的镜像并上传到私有仓库
1）查看镜像
# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
192.168.184.130:5000/lnmp-7-php71 base 9c85344d010f 8 minutes ago 1.26GB
2）给镜像打tag
docker tag 192.168.184.130:5000/lnmp-7-php71:base 192.168.184.130:5000/lnmp-7-php71:v3
3）上传到私有仓库
docker push 192.168.184.130:5000/lnmp-7-php71:v3
4）查看镜像仓库
curl http://192.168.184.130:5000/v2/lnmp-7-php71/tags/list
{"name":"lnmp-7-php71","tags":["base","v3","redis","redisv1","redisv2"]}7 测试使用镜像
1) run起来一个php
docker run -d -p 9000:9000 --name php-test 192.168.184.130:5000/lnmp-7-php71:v3
2）查看docker是否运行
# docker ps | grep php-test
5ad6cbbaf728 192.168.184.130:5000/lnmp-7-php71:v3 "/bin/sh -c '/etc/in…" 5 minutes ago Up 5 minutes 0.0.0.0:9000->9000/tcp, 9006/tcp php-test
3）查看端口
# ss -anlptu | grep 9000
tcp LISTEN 0 128 :::9000 :::* users:(("docker-proxy",pid=7340,fd=4))
4）查看日志
# docker logs php-test -f
Starting php-fpm done8 添加redis扩展
1）创建php-redisDocker文件目录
#mkdir redis
2) 以php-test 192.168.184.130:5000/lnmp-7-php71:v3为基础镜像添加redis扩展
# cat Dockerfile
FROM 192.168.184.130:5000/lnmp-7-php71:v3
MAINTAINER swift
RUN cd /usr/local/src && \
git clone https://github.com/phpredis/phpredis.git phpredis71 && \
cd phpredis71 && \
/usr/local/php71/bin/phpize && \
./configure --with-php-config=/usr/local/php71/bin/php-config && \
make && make install
3) build镜像
#docker build -t 192.168.184.130:5000/lnmp-7-php71:redis .
4）给镜像打tag
#docker tag 192.168.184.130:5000/lnmp-7-php71:redis 192.168.184.130:5000/lnmp-7-php71:redisv2
5）上传到私有仓库
#docker push 192.168.184.130:5000/lnmp-7-php71:redisv2
6）创建php.ini配置文件
#cat php.ini
extension=redis.so
7）创建测试容器验证
#docker run -d -p 9006:9000 -v /root/redis/php.ini:/usr/local/php71/etc/php.ini --name php-test-redis 192.168.184.130:5000/lnmp-7-php71:redisv2
8）查看redis模块是否加载
#docker exec -it php-test-redis bash -c '/usr/local/php71/bin/php -m | grep redis'
redis
